Guidelines for prevention of hospital acquired infections PubMed Central Mehta, Yatin; Gupta, Abhinav; Todi, Subhash; Myatra, SN; Samaddar, D. P.; Patil, Vijaya; Bhattacharya, Pradip Kumar; Ramasubban, Suresh 2014-01-01 These guidelines, written for clinicians, contains evidence-based recommendations for the prevention of hospital acquired infections Hospital acquired infections are a major cause of mortality and morbidity and provide challenge to clinicians. Measures of infection control include identifying patients at risk of nosocomial infections, observing hand hygiene, following standard precautions to reduce transmission and strategies to reduce VAP, CR-BSI, CAUTI. Environmental factors and architectural lay out also need to be emphasized upon. Infection prevention in special subsets of patients - burns patients, include identifying sources of organism, identification of organisms, isolation if required, antibiotic prophylaxis to be used selectively, early removal of necrotic tissue, prevention of tetanus, early nutrition and surveillance. Immunodeficient and Transplant recipients are at a higher risk of opportunistic infections. The post tranplant timetable is divided into three time periods for determining risk of infections. Room ventilation, cleaning and decontamination, protective clothing with care regarding food requires special consideration. Monitoring and Surveillance are prioritized depending upon the needs. Designated infection control teams should supervise the process and help in collection and compilation of data. Antibiotic Stewardship Recommendations include constituting a team, close coordination between teams, audit, formulary restriction, de-escalation, optimizing dosing, active use of information technology among other measure. The recommendations in these guidelines are intended to support, and not replace, good clinical judgment. The recommendations are rated by a letter that indicates the strength of the recommendation and a Roman numeral that indicates the quality of evidence supporting the recommendation, so that readers can ascertain how best to apply the recommendations in their practice environments.

PubMed Bender, Jeffrey M; Virgallito, Mary; Newland, Jason G; Sammons, Julia S; Thorell, Emily A; Coffin, Susan E; Pavia, Andrew T; Sandora, Thomas J; Hersh, Adam L 2015-05-01 We surveyed hospital epidemiologists at 28 Children's Hospital Association member hospitals regarding their infection prevention and control programs. We found substantial variability between children's hospitals in both the structure and the practice of these programs. Research and the development of evidence-based guidelines addressing infection prevention in pediatrics are needed. 4. State of Infection Prevention in US Hospitals Enrolled in NHSN PubMed Central Pogorzelska-Maziarz, Monika; Herzig, Carolyn T. A.; Weiner, Lindsey M.; Furuya, E. Yoko; Dick, Andrew; Larson, Elaine 2014-01-01 Background This report provides a national cross-sectional snapshot of infection prevention and control programs and clinician compliance with the implementation of processes to prevent healthcare associated infections (HAI) in intensive care units (ICUs). Methods All hospitals, except for Veterans Affairs hospitals, enrolled in the National Healthcare Safety Network (NHSN) were eligible to participate. Participation included: 1) completion of a survey that assessed presence of evidence-based prevention policies and clinician adherence, and 2) joining our NHSN research group. Descriptive statistics were computed. Facility characteristics and HAI rates by ICU type were compared between respondents and nonrespondents. Results Of the 3,374 eligible hospitals, 975 hospitals provided data (29% response rate) on 1,653 ICUs; and, there were complete data on the presence of policies in 1,534 ICUs. The average number of infection preventionists (IPs) per 100 beds was 1.2. Certification of IP staff varied across institutions and the average hours per week of data management and secretarial support were generally low. There was variation in the presence of policies and clinician adherence to these policies. There were no differences in HAI rates between respondents and non-respondents. Conclusions Guidelines around IP staffing in acute care hospitals should be updated. In future publications we will analyze the associations between HAI rates and infection prevention and control program characteristics, presence of and clinician adherence to evidence-based policies.

PubMed Apisarnthanarak, Anucha; Mundy, Linda M; Khawcharoenporn, Thana; Glen Mayhall, C 2013-02-01 The devastating clinical and economic implications of floods exemplify the need for effective global infection prevention and control (IPC) strategies for natural disasters. Reopening of hospitals after excessive flooding requires a balance between meeting the medical needs of the surrounding communities and restoration of a safe hospital environment. Postflood hospital preparedness plans are a key issue for infection control epidemiologists, healthcare providers, patients, and hospital administrators. We provide recent IPC experiences related to reopening of a hospital after extensive black-water floods necessitated hospital closures in Thailand and the United States. These experiences provide a foundation for the future design, execution, and analysis of black-water flood preparedness plans by IPC stakeholders. 6. Infection Control and Prevention: A Review of Hospital-Acquired Infections and the Economic Implications PubMed Central Reed, Deoine; Kemmerly, Sandra A. 2009-01-01 The Centers for Disease Control and Prevention estimates that 2 million patients suffer from hospital-acquired infections every year and nearly 100,000 of them die. Most of these medical errors are preventable. Hospital-acquired infections result in up to $4.5 billion in additional healthcare expenses annually. The U.S. government has responded to this financial loss by focusing on healthcare quality report cards and by taking strong action to curb healthcare spending. The Medicare Program has proposed changes to the Hospital Inpatient Prospective Payment System and Fiscal Year Rates: Proposed Rule CMS 1488-P-Healthcare-associated infection. Payment will be linked to performance. Under the new rule, payment will be withheld from hospitals for care associated with treating certain catheter-associated urinary tract infections, vascular catheter-associated infections, and mediastinitis after coronary artery bypass graft surgery. Infection-prevention strategies are essential. In the healthcare setting, the infection control department is categorized as nonrevenue-producing. Funds dedicated to resources such as staff, educational programs, and prevention measures are vastly limited. Hospital leaders will need to balance the upfront cost needed to prevent hospital-related infections with the non-reimbursed expense accrued secondary to potentially preventable infections. The purpose of this paper is to present case studies and cost analysis of hospital-acquired infections and present strategies that reduce infections and cost. PMID:21603406 7.

Economics and preventing hospital-acquired infection: broadening the perspective. PubMed Graves, Nicholas; Halton, Kate; Lairson, David 2007-02-01 To present a hypothetical model of the change in economic costs and health benefits to society that result from nosocomial infection control programs. We use a modeling framework to represent how 2 types of costs change with nosocomial infection control programs: costs incurred by the hospital sector and community health services, as well as the private costs to patients. We also demonstrate how to value the health benefits of nosocomial infection control programs, using quality-adjusted life years. Hypothetical modeling to incorporate the societal perspective. A cohort of 50,000 simulated patients at risk of surgical site infection following total hip replacement. A total of 8 hypothetical interventions that change costs and health outcomes among the cohort by preventing cases of surgical site infection following total hip replacement. We demonstrate that when infection control interventions reduce economic costs and increase health benefits, they should be adopted without further question. If, however, interventions increase economic costs and increase health benefits, then the trade-off between costs and benefits should be examined. Decision-makers should assess the cost per unit of health benefit from infection control programs, consider the impact on health budgets, and compare infection control with alternative uses of scarce healthcare resources. 9. [Infection prevention in Dutch hospitals; results say more than process indicators]. PubMed Bonten, Marc J M; Friedrich, Alexander; Kluytmans, Jan A J W; Vandenbroucke-Grauls, Christina M J E; Voss, Andreas; Vos, Margreet C 2014-01-01 The Dutch Health Care Inspectorate investigated the preparedness of Dutch hospitals for the emergence of antibiotic resistance, and concluded that hospitals are not well prepared and are insufficiently aware that infection prevention is a prerequisite for patient safety. These conclusions are based on observations of process indicators of current practice guidelines, without including the available outcome indicators that demonstrate the persistently low incidence of infections with antibiotic resistant bacteria in Dutch hospitals. The conclusions may have negative effects on the quality of infection prevention in Dutch hospitals. Therefore, it is advisable to use outcome indicators rather than process indicators to evaluate the quality of infection prevention. 10. Hospital ward design and prevention of hospital-acquired infections: A prospective clinical trial. PubMed Ellison, Jennifer; Southern, Danielle; Holton, Donna; Henderson, Elizabeth; Wallace, Jean; Faris, Peter; Ghali, William A; Conly, John 2014-09-01 Renovation of a general medical ward provided an opportunity to study health care facility design as a factor for preventing hospital-acquired infections. To determine whether a hospital ward designed with predominantly single rooms was associated with lower event rates of hospital-acquired infection and colonization. A prospective controlled trial with patient allocation incorporating randomness was designed with outcomes on multiple 'historic design' wards (mainly four-bed rooms with shared bathrooms) compared with outcomes on a newly renovated 'new design' ward (predominantly single rooms with private bathrooms). Using Poisson regression analysis and adjusting for time at risk, there were no differences (P=0.18) in the primary outcome (2.96 versus 1.85 events/1000 patient-days, respectively). After adjustment for age, sex, Charlson score, admitted from care facility, previous hospitalization within six months, isolation requirement and the duration on antibiotics, the incidence rate ratio was 1.44 (95% CI 0.71 to 2.94) for the new design versus the historic design wards. A restricted analysis on the numbers of events occurring in single-bed versus multibed wings within the new design ward revealed an event incidence density of 1.89 versus 3.47 events/1000 patient-days, respectively (P=0.18), and an incidence rate ratio of 0.54 (95% CI 0.15 to 1.30). No difference in the incidence density of hospitalacquired infections or colonizations was observed for medical patients admitted to a new design ward versus historic design wards. A restricted analysis of events occurring in singlebed versus multibed wings suggests that ward design warrants further study. 11. Infection prevention needs assessment in Colorado hospitals: rural and urban settings. PubMed Reese, Sara M; Gilmartin, Heather; Rich, Karen L; Price, Connie S 2014-06-01 The purpose of our study was to conduct a needs assessment for infection prevention programs in both rural and urban hospitals in Colorado. Infection control professionals (ICPs) from Colorado hospitals participated in an online survey on training, personnel, and experience; ICP time allocation; and types of surveillance. Responses were evaluated and compared based on hospital status (rural or urban). Additionally, rural ICPs participated in an interview about resources and training. Surveys were received from 62 hospitals (77.5% response); 33 rural (75.0% response) and 29 urban (80.6% response). Fifty-two percent of rural ICPs reported multiple job responsibilities compared with 17.2% of urban ICPs. Median length of experience for rural ICPs was 4.0 years compared with 11.5 years for urban ICPs (P = .008). Fifty-one percent of rural ICPs reported no access to infectious disease physicians (0.0% urban) and 81.8% of rural hospitals reported no antimicrobial stewardship programs (31.0% urban). Through the interviews it was revealed that priorities for rural ICPs were training and communication. Our study revealed numerous differences between infection prevention programs in rural versus urban hospitals. An infection prevention outreach program established in Colorado could potentially address the challenges faced by rural hospital infection prevention departments.

Prevention of hospital-acquired infections by selective digestive decontamination. PubMed Reed, R Lawrence 2011-06-01 Selective decontamination of the digestive tract (SDD) has been advocated to prevent ventilator-associated pneumonia (VAP) and possibly other nosocomial infections. However, its incorporation into standard health care practices has been limited. Comprehensive literature search using www.pubmed.gov and derivative cross-references. The abundance of basic science and clinical literature largely supports the concept that the incidence of VAP declines after the introduction of SDD, although there are some controversial aspects. Several meta-analyses and recent controlled clinical trials have supported the benefit of SDD. A few years ago, the Institute for Healthcare Improvement introduced the "ventilator bundle," a set of simple evidence-based measures designed to reduce the incidence of pneumonia. These measures have been implemented rapidly throughout the country. Of the four initial measures (elevation of the head of the bed, daily "sedation vacations" with assessment of readiness for endotracheal extubation, prophylaxis against stress-related gastric mucosal hemorrhage, and deep venous thrombosis prophylaxis), only the first two affect the development of VAP either directly or indirectly. The evidence supporting SDD as a prevention measure for VAP is at least as good as that supporting the ventilator bundle, if not better. At many centers, a topical oral antiseptic (e.g., chlorhexidine) has been incorporated as a fifth element of the ventilator bundle. 13. Infection Prevention in the Hospital from Past to Present: Evolving Roles and Shifting Priorities. PubMed Doll, Michelle; Hewlett, Angela L; Bearman, Gonzalo 2016-05-01 Hospital epidemiologists are vital components of integrated health centers. This central place in the healthcare landscape has rapidly evolved over a half century. Early hospital epidemiologists possessed a visionary focus on patient safety many decades prior to the quality revolution of the 1990s. A systematic and scientific approach to infection prevention has facilitated the evolution of hospital epidemiology, along with advances in technology, and increasing public attention to infectious complications in the hospital. Currently, the growing expansion of tasks and moving regulatory targets strain existing resources. These challenges threaten to limit the effectiveness of some infection-prevention activities, while also providing important opportunities for improving care. It will be increasingly important to advocate for appropriate resources to address a diverse set of changing infection prevention priorities. 14. Strategies to Prevent Surgical Site Infections in Acute Care Hospitals: 2014 Update PubMed Central Anderson, Deverick J.; Podgorny, Kelly; BerrÃos-Torres, Sandra I.; Bratzler, Dale W.; Dellinger, E. Patchen; Greene, Linda; Nyquist, Ann-Christine; Saiman, Lisa; Yokoe, Deborah S.; Maragakis, Lisa L.; Kaye, Keith S. 2014-01-01 PURPOSE Previously published guidelines are available that provide comprehensive recommendations for detecting and preventing healthcare-associated infections (HAIs). The intent of this document is to highlight practical recommendations in a concise format designed to assist acute care hospitals in implementing and prioritizing their surgical site infection (SSI) prevention efforts. This document updates “Strategies to Prevent Surgical Site Infections in Acute Care Hospitals,â€1 published in 2008.

An image-guided tool to prevent hospital acquired infections NASA Astrophysics Data System (ADS) Nagy, Melinda; Szilágyi, László; Lehotsky, Ãkos; Haidegger, Tamás; Benyó, Balázs 2011-03-01 Hospital Acquired Infections (HAI) represent the fourth leading cause of death in the United States, and claims hundreds of thousands of lives annually in the rest of the world. This paper presents a novel low-cost mobile device|called Stery-Hand|that helps to avoid HAI by improving hand hygiene control through providing an objective evaluation of the quality of hand washing. The use of the system is intuitive: having performed hand washing with a soap mixed with UV re ective powder, the skin appears brighter in UV illumination on the disinfected surfaces. Washed hands are inserted into the Stery-Hand box, where a digital image is taken under UV lighting. Automated image processing algorithms are employed in three steps to evaluate the quality of hand washing. First, the contour of the hand is extracted in order to distinguish the hand from the background. Next, a semi-supervised clustering algorithm classies the pixels of the hand into three groups, corresponding to clean, partially clean and dirty areas. The clustering algorithm is derived from the histogrambased quick fuzzy c-means approach, using a priori information extracted from reference images, evaluated by experts. Finally, the identied areas are adjusted to suppress shading eects, and quantied in order to give a verdict on hand disinfection quality. The proposed methodology was validated through tests using hundreds of images recorded in our laboratory. The proposed system was found robust and accurate, producing correct estimation for over 98% of the test cases. Stery-Hand may be employed in general practice, and it may also serve educational purposes. 16. State of infection prevention in US hospitals enrolled in the National Health and Safety Network.

Vital Signs: Preventing Antibiotic-Resistant Infections in Hospitals - United States, 2014. PubMed Weiner, Lindsey M; Fridkin, Scott K; Aponte-Torres, Zuleika; Avery, Lacey; Coffin, Nicole; Dudeck, Margaret A; Edwards, Jonathan R; Jernigan, John A; Konnor, Rebecca; Soe, Minn M; Peterson, Kelly; McDonald, L Clifford 2016-03-11 Health care-associated antibiotic-resistant (AR) infections increase patient morbidity and mortality and might be impossible to successfully treat with any antibiotic. CDC assessed health care-associated infections (HAI), including Clostridium difficile infections (CDI), and the role of six AR bacteria of highest concern nationwide in several types of health care facilities. During 2014, approximately 4,000 short-term acute care hospitals, 501 long-term acute care hospitals, and 1,135 inpatient rehabilitation facilities in all 50 states reported data on specific infections to the National Healthcare Safety Network. National standardized infection ratios and their percentage reduction from a baseline year for each HAI type, by facility type, were calculated. The proportions of AR pathogens and HAIs caused by any of six resistant bacteria highlighted by CDC in 2013 as urgent or serious threats were determined. In 2014, the reductions in incidence in short-term acute care hospitals and long-term acute care hospitals were 50% and 9%, respectively, for central line-associated bloodstream infection; 0% (short-term acute care hospitals), 11% (long-term acute care hospitals), and 14% (inpatient rehabilitation facilities) for catheter-associated urinary tract infection; 17% (short-term acute care hospitals) for surgical site infection, and 8% (short-term acute care hospitals) for CDI. Combining HAIs other than CDI across all settings, 47.9% of Staphylococcus aureus isolates were methicillin resistant, 29.5% of enterococci were vancomycin-resistant, 17.8% of Enterobacteriaceae were extended-spectrum betalactamase phenotype, 3.6% of Enterobacteriaceae were carbapenem resistant, 15.9% of Pseudomonas aeruginosa isolates were multidrug resistant, and 52.6% of Acinetobacter species were multidrug resistant. The likelihood of HAIs caused by any of the six resistant bacteria ranged from 12% in inpatient rehabilitation facilities to 29% in long-term acute care hospitals. Although 18.

PubMed Borg, M A; Waisfisz, B; Frank, U 2015-05-01 It has been suggested that organizational culture (OC) is an important driver of infection prevention and control (IPC) behaviour among healthcare workers. This study examined OC in seven European hospitals using a validated assessment tool based on Hofstede's model, and identified significant variations in OC scores. Hospitals with low prevalence of meticillin-resistant Staphylococcus aureus (MRSA) exhibited high scores for change facilitation and change readiness, whereas hospitals with high prevalence of MRSA exhibited low scores for these determinants. It is possible to use tools, available outside health care, to study OC within hospitals and gain better insight into IPC behaviour change strategies.

Waterborne microorganisms and biofilms related to hospital infections: strategies for prevention and control in healthcare facilities. PubMed Capelletti, Raquel Vannucci; Moraes, Ângela Maria 2016-02-01 Water is the main stimulus for the development of microorganisms, and its flow has an important role in the spreading of contaminants. In hospitals, the water distribution system requires special attention since it can be a source of pathogens, including those in the form of biofilms often correlated with resistance of microorganisms to various treatments. In this paper, information relevant to cases of nosocomial infections involving water circuits as a source of contaminants is compiled, with emphasis on the importance of microbiological control strategies to prevent the installation, spreading and growth of microorganisms in hospitals. An overview of the worldwide situation is provided, with emphasis on Brazilian hospitals. Different approaches normally used to control the occurrence of nosocomial infections due to waterborne contaminants are analyzed, and the use of the polysaccharide chitosan for this specific application is briefly discussed. 23. Economic Evaluation of Interventions for Prevention of Hospital Acquired Infections: A Systematic Review PubMed Central Kwetkat, Anja 2016-01-01 Objective This systematic review sought to assess the costs and benefits of interventions preventing hospital-acquired infections and to evaluate methodological and reporting quality. Methods We systematically searched Medline via PubMed and the National Health Service Economic Evaluation Database from 2009 to 2014. We included quasi-experimental and randomized trails published in English or German evaluating the economic impact of interventions preventing the four most frequent hospital-acquired infections (urinary tract infections, surgical wound infections, pneumonia, and primary bloodstream infections). Characteristics and results of the included articles were extracted using a standardized data collection form. Study and reporting quality were evaluated using SIGN and CHEERS checklists. All costs were adjusted to 2013 US$. Savings-to-cost ratios and difference values with interquartile ranges (IQRs) per month were calculated, and the effects of study characteristics on the cost-benefit results were analyzed. Results Our search returned 2067 articles, of which 27 met the inclusion criteria. The median savings-to-cost ratio across all studies reporting both costs and savings values was US $7.0 (IQR 4.2–30.9), and the median net global saving was US $13,179 (IQR 5,106–65,850) per month. The studies’ reporting quality was low. Only 14 articles reported more than half of CHEERS items appropriately. Similarly, an assessment of methodological quality found that only four studies (14.8%) were considered high quality. Conclusions Prevention programs for hospital acquired infections have very positive cost-benefit ratios. Improved reporting quality in health economics publications is required. PMID:26731736 24. Value of Public Health Funding in Preventing Hospital Bloodstream Infections in the United States. PubMed Whittington, Melanie D; Bradley, Cathy J; Atherly, Adam J; Campbell, Jonathan D; Lindrooth, Richard C 2017-11-01 To estimate the association of 1 activity of the Prevention and Public Health Fund with hospital bloodstream infections and calculate the return on investment (ROI). The activity was funded for 1 year (2013). A difference-in-differences specification evaluated hospital standardized infection ratios (SIRs) before funding allocation (years 2011 and 2012) and after funding allocation (years 2013 and 2014) in the 15 US states that received the funding compared with hospital SIRs in states that did not receive the funding. We estimated the association of the funded public health activity with SIRs for bloodstream infections. We calculated the ROI by dividing cost offsets from infections averted by the amount invested. The funding was associated with a 33% (P  80% agreement was achieved on all competency statements and terminal objectives. The final matrix of competencies and terminal objectives developed through this process may be used as a content framework for educational curricula and training materials for hospital-based health care personnel. The process also may be of use in determining the core competencies and terminal objectives regarding infection prevention and control for health care personnel in other settings. Validation of these results is an important next step. 26. Knowledge sharing and organizational learning in the context of hospital infection prevention. PubMed Rangachari, Pavani 2010-01-01 Recently, hospitals that have been successful in preventing infections have labeled their improvement approaches as either the Toyota Production System (TPS) approach or the Positive Deviance (PD) approach. PD has been distinguished from TPS as being a bottom-up approach to improvement, as against top-down. Facilities that have employed both approaches have suggested that PD may be more effective than TPS for infection prevention. This article integrates organizational learning, institutional, and knowledge network theories to develop a theoretical framework for understanding the structure and evolution of effective knowledge-sharing networks in health care organizations, that is, networks most conducive to learning and improvement. Contrary to arguments put forth by hospital success stories, the framework suggests that networks rich in brokerage and hierarchy (ie, topdown, "TPS-like" structures) may be more effective for learning and improvement in health care organizations, compared with a networks rich in density (ie, bottom-up, "PD-like" structures). The theoretical framework and ensuing analysis help identify several gaps in the literature related to organization learning and improvement in the infection prevention context. This, in turn, helps put forth recommendations for health management research and practice. 27. Clostridium Difficile Infection in Acute Care Hospitals: Systematic Review and Best Practices for Prevention. PubMed Louh, Irene K; Greendyke, William G; Hermann, Emilia A; Davidson, Karina W; Falzon, Louise; Vawdrey, David K; Shaffer, Jonathan A; Calfee, David P; Furuya, E Yoko; Ting, Henry H 2017-04-01 OBJECTIVE Prevention of Clostridium difficile infection (CDI) in acute-care hospitals is a priority for hospitals and clinicians. We performed a qualitative systematic review to update the evidence on interventions to prevent CDI published since 2009. DESIGN We searched Ovid, MEDLINE, EMBASE, The Cochrane Library, CINAHL, the ISI Web of Knowledge, and grey literature databases from January 1, 2009 to August 1, 2015. SETTING We included studies performed in acute-care hospitals. PATIENTS OR PARTICIPANTS We included studies conducted on hospitalized patients that investigated the impact of specific interventions on CDI rates. INTERVENTIONS We used the QIMinimum Quality Criteria Set (QI-MQCS) to assess the quality of included studies. Interventions were grouped thematically: environmental disinfection, antimicrobial stewardship, hand hygiene, chlorhexidine bathing, probiotics, bundled approaches, and others. A meta-analysis was performed when possible. RESULTS Of 3,236 articles screened, 261 met the criteria for full-text review and 46 studies were ultimately included. The average quality rating was 82% according to the QI-MQCS. The most effective interventions, resulting in a 45% to 85% reduction in CDI, included daily to twice daily disinfection of high-touch surfaces (including bed rails) and terminal cleaning of patient rooms with chlorine-based products. Bundled interventions and antimicrobial stewardship showed promise for reducing CDI rates. Chlorhexidine bathing and intensified hand-hygiene practices were not effective for reducing CDI rates. CONCLUSIONS Daily and terminal cleaning of patient rooms using chlorine-based products were most effective in reducing CDI rates in hospitals. Further studies are needed to identify the components of bundled interventions that reduce CDI rates. Infect Control Hosp Epidemiol 2017;38:476-482. 28.

Variables for adherence to the central line bundle, organizational context, and central line-associated bloodstream infections (CLABSIs) were selected for this secondary data analysis from 614 US hospitals that participated in the Prevention of Nosocomial Infection and Cost-effectiveness-Refined study. One half of the dataset was used for exploration of the concepts, the second half for confirmation of the measurement models and testing of the structural model. The final model resulted in a good fit to the data (χ (1215) = 1906.86, P < .00; comparative fit index = 0.94; root mean square of error of approximation = 0.04). A significant relationship was noted between adherence to the central line bundle interventions and organizational context (β = 0.23, P < .01), whereas the relationship between context and CLABSIs was not significant (β = -0.20, P = .78). This study supports a relationship between greater adherence to HAI interventions and higher levels of organizational context and highlights the complexity of measuring organizational context. Given the importance of preventing HAIs, ongoing research is needed to reveal the exact aspects of context that influence interventions and outcomes. 29. [Patient-oriented prevention and control of hospital-acquired infections (author's transl)]. PubMed Daschner, F 1979-11-15 The incidence of hospital-acquired infections varies between 2 and 15% (on average 5 to 8%). Most common nosocomial infections are urinary tract infections, wound infections, respiratory tract infections, septicemia and infections of the skin and subcutaneous tissue. Nosocomial infections arise essentially via two routes: endogenously from the bodies own flora or exogenously via direct or indirect contact with the patient. Bacteria are most commonly transmitted from patient to patient by hands. Air as a vehicle, by which bacteria are transmitted, plays a relatively minor role. Priorities in hospital infection control are: hand washing and hand desinfection, improvement of certain nursing techniques, isolation of infected or susceptible patients, an infection control team with a nurse epidemiologist, surveillance and control of antibiotic therapy regimens, especially of antibiotic prophylaxis. Routine floor desinfection could not be shown to significantly reduce the hospital infection rate. 30. CLOSTRIDIUM DIFFICILE INFECTION IN ACUTE CARE HOSPITALS: SYSTEMATIC REVIEW AND BEST PRACTICES FOR PREVENTION PubMed Central Louh, Irene K.; Greendyke, William G.; Hermann, Emilia A.; Davidson, Karina W.; Falzon, Louise; Vawdrey, David K.; Shaffer, Jonathan A.; Calfee, David P.; Furuya, E. Yoko; Ting, Henry H. 2017-01-01 Objective Prevention of Clostridium difficile infection (CDI) in acute care hospitals is a priority for hospitals and clinicians. We performed a qualitative systematic review to update the evidence on interventions to prevent CDI published since 2009. Design We searched Ovid, MEDLINE, EMBASE, The Cochrane Library, CINAHL, ISI Web of Knowledge, and grey literature databases from January 1, 2009 to August 1, 2015. Setting We included studies performed in acute care hospitals. Patients or participants We included studies conducted on hospitalized patients that investigated the impact of specific interventions on CDI rates. Interventions We used the QI-Minimum Quality Criteria Set (QI-MQCS) to assess the quality of included studies. Interventions were grouped thematically: environmental disinfection, antimicrobial stewardship, hand hygiene, chlorhexidine bathing, probiotics, bundled approaches, and others. A meta-analysis was performed when possible. Results Of 3236 articles screened, 261 met the criteria for full-text review and 46 studies were ultimately included. The average quality rating was 82% on the QI-MQCS. The most effective interventions, resulting in a 45% to 85% reduction in CDI, included daily to twice daily disinfection of high-touch surfaces (including bed rails) and terminal cleaning of patient rooms with chlorine-based products. Bundled interventions and antimicrobial stewardship showed promise for reducing CDI rates. Chlorhexidine bathing and intensified hand hygiene practices were not effective for reducing CDI rates. Conclusions Daily and terminal cleaning of patient rooms using chlorine-based products were most effective in reducing CDI rates in hospitals. Further studies are needed to identify the components of bundled interventions that reduce CDI rates. PMID:28300019 31. Hospital adoption of automated surveillance technology and the implementation of infection prevention and control programs. PubMed Halpin, Helen; Shortell, Stephen M; Milstein, Arnold; Vanneman, Megan 2011-05-01 This research analyzes the relationship between hospital use of automated surveillance technology (AST) for identification and control of hospital-acquired infections (HAI) and implementation of evidence-based infection control practices. Our hypothesis is that hospitals that use AST have made more progress implementing infection control practices than hospitals that rely on manual surveillance. A survey of all acute general care hospitals in California was conducted from October 2008 through January 2009. A structured computerassisted telephone interview was conducted with the quality director of each hospital. The final sample includes 241 general acute care hospitals (response rate, 83%). Approximately one third (32.4%) of California's hospitals use AST for monitoring HAI. Adoption of AST is statistically significant and positively associated with the depth of implementation of evidence-based practices for methicillin-resistant Staphylococcus aureus and ventilator-associated pneumonia and adoption of contact precautions and surgical care infection practices. Use of AST is also statistically significantly associated with the breadth of hospital implementation of evidence-based practices across all 5 targeted HAI. Our findings suggest that hospitals using AST can achieve greater depth and breadth in implementing evidenced-based infection control practices.

Hygiene training of food handlers in hospital settings: important factor in the prevention of nosocomial infections. PubMed Lazarević, Konstansa; Stojanović, Dusica; Bogdanović, Dragan; Dolićanin, Zana 2013-09-01 The aim of this study was to evaluate the effects of food hygiene training of food handlers on sanitary-hygienic conditions in hospital kitchens, based on microbiological analysis of smears taken in hospital kitchens. The study was conducted in the 1995-2009 period at the Clinical Centre Nis, Serbia. The food hygiene training was conducted in February 2005, by an infection control officer. 1,076 smears in the central kitchen and 4,025 smears in distributive kitchens were taken from hands and work clothes, work surfaces, equipment, and kitchen utensils. Microbiological analysis of smears was carried out in an accredited laboratory of the Public Health Institute Nis (Serbia). A significantly lower percentage of smears with isolates of bacteria (p < 0.001) taken from hands and work clothes, work surfaces, equipment and kitchen utensils in the central and distributive kitchens was observed in the period following the food safety education programme (2005-2009). The most commonly isolated bacteria was: Enterobacter spp., Acinetobacter spp., Citrobacter spp., and E. coli. Our results confirmed that food hygiene training improved hygiene and is also an important component for the prevention of nosocomial infection. 33. Nitric oxide charged catheters as a potential strategy for prevention of hospital acquired infections PubMed Central Regev-Shoshani, Gili; KO, Mary; Moshe, Maya; Ozalvo, Rachel; Shavit-Grievink, Liat; Baniel, Jack; Kedar, Daniel; Yossepowitch, Ofer; Lifshitz, David; Nadu, Andrei; Greenberg, David; Av-Gay, Yossef 2017-01-01 Background Catheter-Associated Hospital-Acquired Infections (HAI's) are caused by biofilm-forming bacteria. Using a novel approach, we generated anti-infective barrier on catheters by charging them with Nitric Oxide (NO), a naturally-produced gas molecule. NO is slowly released from the catheter upon contact with physiological fluids, and prevents bacterial colonization and biofilm formation onto catheter surfaces. Aims and methods The aim of the study was to assess the anti-infective properties of NO-charged catheters exposed to low concentration (up to 103 CFU/ml) of microbial cells in-vitro. We assessed NO-charged tracheal tubes using Pseudomonas aeruginosa, dialysis and biliary catheters using Escherichia coli, and urinary catheters using E. coli, Candida albicans or Enterococcus faecalis. Safety and tolerability of NO-charged urinary catheters were evaluated in a phase 1 clinical study in 12 patients. Six patients were catheterized with NO-charged catheters (NO-group), followed by 6 patients catheterized with regular control catheters (CTgroup). Comparison of safety parameters between the study groups was performed. Results NO-charged tracheal, dialysis biliary and urinary catheters prevented P. aeruginosa, E. coli and C. albicans attachment and colonization onto their surfaces and eradicated corresponding planktonic microbial cells in the surrounding media after 24–48 hours, while E. faecalis colonization onto urinary catheters was reduced by 1 log compared to controls. All patients catheterized with an NO-charged urinary catheter successfully completed the study without experiencing NO-related AE's or serious AE's (SAE's). Conclusion These data highlight the potential of NO-based technology as potential platform for preventing catheter-associated HAI's. PMID:28410367 34. Strategies for the prevention of hospital-acquired infections in the neonatal intensive care unit. PubMed Borghesi, A; Stronati, M 2008-04-01 Nosocomial infections are among the leading causes of mortality and morbidity in neonatal intensive care units. Prevention of healthcare-associated infections is based on strategies that aim to limit susceptibility to infections by enhancing host defences, interrupting transmission of organisms by healthcare workers and by promoting the judicious use of antimicrobials. Several strategies are available and include: hand hygiene practices; prevention of central venous catheter-related bloodstream infections; judicious use of antimicrobials for therapy and prophylaxis; enhancement of host defences; skin care; and early enteral feeding with human milk. 35. Hospital organisation, management, and structure for prevention of health-care-associated infection: a systematic review and expert consensus.

We did a systematic review to identify crucial elements for the organisation of effective infection-prevention programmes in hospitals and key components for implementation of monitoring. 92 studies published from 1996 to 2012 were assessed and ten key components identified: organisation of infection control at the hospital level; bed occupancy, staffing, workload, and employment of pool or agency nurses; availability of and ease of access to materials and equipment and optimum ergonomics; appropriate use of guidelines; education and training; auditing; surveillance and feedback; multimodal and multidisciplinary prevention programmes that include behavioural change; engagement of champions; and positive organisational culture. These components comprise manageable and widely applicable ways to reduce health-care-associated infections and improve patients' safety. Copyright © 2015 Elsevier Ltd. All rights reserved. 36. Taking advantage of public reporting: An infection composite score to assist evaluating hospital performance for infection prevention efforts. PubMed Fakih, Mohamad G; Skierczynski, Boguslow; Bufalino, Angelo; Groves, Clariecia; Roberts, Phillip; Heavens, Michelle; Hendrich, Ann; Haydar, Ziad 2016-12-01 The standardized infection ratio (SIR) evaluates individual publicly reported health care-associated infections, but it may not assess overall performance. We piloted an infection composite score (ICS) in 82 hospitals of a single health system. The ICS is a combined score for central line-associated bloodstream infections, catheter-associated urinary tract infections, colon and abdominal hysterectomy surgical site infections, and hospital-onset methicillin-resistant Staphylococcus aureus bacteremia and Clostridium difficile infections. Individual facility ICSs were calculated by normalizing each of the 6 SIR events to the system SIR for baseline and performance periods (ICS ib and ICS ip , respectively). A hospital ICS ib reflected its baseline performance compared with system baseline, whereas a ICS ip provided information of its outcome changes compared with system baseline. Both the ICS ib (baseline 2013) and ICS ip (performance 2014) were calculated for 63 hospitals (reporting at least 4 of the 6 event types). The ICS ip improved in 36 of 63 (57.1%) hospitals in 2014 when compared with the ICS ib in 2013. The ICS ib 2013 median was 0.96 (range, 0.13-2.94) versus the 2014 ICS ip median of 0.92 (range, 0-6.55). Variation was more evident in hospitals with ≤100 beds. The system performance score (ICS sp ) in 2014 was 0.95, a 5% improvement compared with 2013. The proposed ICS may help large health systems and state hospital associations better evaluate key infectious outcomes, comparing them with historic and concurrent performance of peers.

Implementation of tuberculosis infection control measures in designated hospitals in Zhejiang Province, China: are we doing enough to prevent nosocomial tuberculosis infections? PubMed Central Chen, Bin; Liu, Min; Gu, Hua; Wang, Xiaomeng; Qiu, Wei; Shen, Jian; Jiang, Jianmin 2016-01-01 Objectives Tuberculosis (TB) infection control measures are very important to prevent nosocomial transmission and protect healthcare workers (HCWs) in hospitals. The TB infection control situation in TB treatment institutions in southeastern China has not been studied previously. Therefore, the aim of this study was to investigate the implementation of TB infection control measures in TB-designated hospitals in Zhejiang Province, China. Design Cross-sectional survey using observation and interviews. Setting All TB-designated hospitals (n=88) in Zhejiang Province, China in 2014. Primary and secondary outcome measures Managerial, administrative, environmental and personal infection control measures were assessed using descriptive analyses and univariate logistic regression analysis. Results The TB-designated hospitals treated a median of 3030 outpatients (IQR 764–7094) and 279 patients with confirmed TB (IQR 154–459) annually, and 160 patients with TB (IQR 79–426) were hospitalised in the TB wards. Most infection control measures were performed by the TB-designated hospitals. Measures including regular monitoring of TB infection control in high-risk areas (49%), shortening the wait times (42%), and providing a separate waiting area for patients with suspected TB (46%) were sometimes neglected. N95 respirators were available in 85 (97%) hospitals, although only 44 (50%) hospitals checked that they fit. Hospitals with more TB staff and higher admission rates of patients with TB were more likely to set a dedicated sputum collection area and to conduct annual respirator fit testing. Conclusions TB infection control measures were generally implemented by the TB-designated hospitals. Measures including separation of suspected patients, regular monitoring of infection control practices, and regular fit testing of respirators should be strengthened. Infection measures for sputum collection and respirator fit testing should be improved in hospitals with lower admission 38.

PubMed Borg, M A; Hulscher, M; Scicluna, E A; Richards, J; Azanowsky, J-M; Xuereb, D; Huis, A; Moro, M L; Maltezou, H C; Frank, U 2014-08-01 There is evidence that meticillin-resistant Staphylococcus aureus (MRSA) bacteraemia can be reduced with improved infection control and antibiotic stewardship. To survey infection control and antibiotic stewardship practices within European hospitals and to identify initiatives that correlate with reduced MRSA prevalence. Online questionnaires were sent to European hospitals about their surveillance, hand hygiene, intravenous device management, admission screening, isolation, antibiotic prescribing, hospital demographics and MRSA blood culture isolates during 2010. In all, 269 replies were received from hospitals in 29 European countries. Lower MRSA prevalence showed significant association with presence of incidence surveillance, performance of root cause analysis, mandatory training requirements for hand hygiene, accountability measures for persistent non-compliance, and multistakeholder teamwork in antibiotic prescribing. Presence of policies on intravenous catheter insertion and management showed no variation between different MRSA prevalence groups. However, low-prevalence hospitals reported more competency assessment programmes in insertion and maintenance of peripheral and central venous catheters. Hospitals from the UK and Ireland reported the highest uptake of infection control and antibiotic stewardship practices that were significantly associated with low MRSA prevalence, whereas Southern European hospitals exhibited the lowest. In multiple regression analysis, isolation of high-risk patients, performance of root cause analysis, obligatory training for nurses in hand hygiene, and undertaking joint ward rounds including microbiologists and infectious disease physicians remained significantly associated with lower MRSA prevalence. Proactive infection control and antibiotic stewardship initiatives that instilled accountability, ownership, teamwork, and validated competence among healthcare workers were associated with improved MRSA outcomes.

40. Strategy and technology to prevent hospital-acquired infections: Lessons from SARS, Ebola, and MERS in Asia and West Africa. PubMed Rajakaruna, Sanjeewa Jayachandra; Liu, Wen-Bin; Ding, Yi-Bo; Cao, Guang-Wen 2017-10-27 Hospital-acquired infections (HAIs) are serious problems for healthcare systems, especially in developing countries where public health infrastructure and technology for infection preventions remain undeveloped. Here, we characterized how strategy and technology could be mobilized to improve the effectiveness of infection prevention and control in hospitals during the outbreaks of Ebola, Middle East respiratory syndrome (MERS), and severe acute respiratory syndrome (SARS) in Asia and West Africa. Published literature on the hospital-borne outbreaks of SARS, Ebola, and MERS in Asia and West Africa was comprehensively reviewed. The results showed that healthcare systems and hospital management in affected healthcare facilities had poor strategies and inadequate technologies and human resources for the prevention and control of HAIs, which led to increased morbidity, mortality, and unnecessary costs. We recommend that governments worldwide enforce disaster risk management, even when no outbreaks are imminent. Quarantine and ventilation functions should be taken into consideration in architectural design of hospitals and healthcare facilities. We also recommend that health authorities invest in training healthcare workers for disease outbreak response, as their preparedness is essential to reducing disaster risk. « 1 2 3 4 5 » « 1 2 3 4 5 » 41. Examining the online approaches used by hospitals in Sydney, Australia to inform patients about healthcare associated infections and infection prevention strategies. PubMed Park, J; Seale, H 2017-12-21 Provision of information plays a critical role in supporting patients to be engaged or empowered to be involved with infection prevention measures in hospitals. This explorative study evaluated the suitability, readability and accessibility of information on healthcare associated infections (HCAIs) and infection prevention strategies targeted at patients from the websites of 19 acute care public hospitals in Sydney, Australia. We included hospitals with greater than 200 beds in the sample. We examined online information targeted at patients on HCAIs and infection prevention and compared it using the Suitability Assessment of Material (SAM) and Simple Measure of Gobbledygook (SMOG) readability formulas for suitability, readability and accessibility. Thirty-six webpages were identified as being relevant and containing information about HCAIs or infection prevention. Based on the SAM/SMOG scores, only three webpages were found to be 'superior'. Many of the webpages scored poorly in content, literacy, graphics, learning stimulation and cultural appropriateness. In comparison, most of the webpages scored well in the layout and typography. The majority (97%) of the materials were written at a level higher than the recommended reading grade level. Lastly, the websites scored poorly on the ability to locate the information easily, as messages about HCAIs/infection prevention were usually embedded into other topics. While providing information online is only one approach to delivering messages about infection prevention, it is becoming increasingly important in today's technology society. Hospitals are neglecting to use best practices when designing their online resources and current websites are difficult to navigate. The findings point to the need to review patient information on HCAIs regarding suitability, readability and accessibility. 42. Determining the status quo of infection prevention and control standards in the hospitals of iran: a case study in 23 hospitals.

The current study aimed to determine the status quo of international standards of PCI in hospitals located in the north of Iran. This cross-sectional study was conducted in 23 hospitals. Data collection tool was a questionnaire with confirmed validity and reliability. . In this regard, 260 managers, section supervisors and infection control nurses participated in the study according to census basis. SPSS software version 16 was employed to analyze the data through descriptive and analytical statistics. Among the studied hospitals, 18 hospitals were public. Hospitals enjoyed 77.2% of leadership and programming, 80.8% of focus of programs, 67.4% of isolating methods, 88.2% of hand health and protection techniques, 78.8% of improving patient's safety and quality, 90.3% of training personnel, and 78.7% of the average status quo of PCI standards. This study revealed that PCI standards were significantly observed in the studied hospitals and that there were necessary conditions for full deployment of nosocomial infection surveillance. 43. Implementation of the updated 2015 Commission for Hospital Hygiene and Infection Prevention (KRINKO) recommendations "Prevention and control of catheter-associated urinary tract infections" in the hospitals in Frankfurt/Main, Germany. PubMed Heudorf, Ursel; Grünewald, Miriam; Otto, Ulla 2016-01-01 The Commission for Hospital Hygiene and Infection Prevention (KRINKO) updated the recommendations for the prevention of catheter-associated urinary tract infections in 2015. This article will describe the implementation of these recommendations in Frankfurt's hospitals in autumn, 2015. In two non-ICU wards of each of Frankfurt's 17 hospitals, inspections were performed using a checklist based on the new KRINKO recommendations. In one large hospital, a total of 5 wards were inspected. The inspections covered the structure and process quality (operating instructions, training, indication, the placement and maintenance of catheters) and the demonstration of the preparation for insertion of a catheter using an empty bed and an imaginary patient, or insertion in a model. Operating instructions were available in all hospital wards; approximately half of the wards regularly performed training sessions. The indications were largely in line with the recommendations of the KRINKO. Alternatives to urinary tract catheters were available and were used more often than the urinary tract catheters themselves (15.9% vs. 13.5%). In accordance with the recommendations, catheters were placed without antibiotic prophylaxis or the instillation of antiseptic or antimicrobial substances or catheter flushing solutions. The demonstration of catheter placement was conscientiously performed. Need for improvement was seen in the daily documentation and the regular verification of continuing indication for a urinary catheter, as well as the omission of regular catheter change. Overall, the recommendations of the KRINKO on the prevention of catheter-associated urinary tract infections were adequately implemented. However, it cannot be ruled out that in situations with time pressure and staff shortage, the handling of urinary tract catheters may be of lower quality than that observed during the inspections, when catheter insertion was done by two nurses. Against this background, a sufficient 44. Positive impact of infection prevention on the management of nosocomial outbreaks at an academic hospital. PubMed Dik, Jan-Willem H; Sinha, Bhanu; Lokate, Mariëtte; Lo-Ten-Foe, Jerome R; Dinkelacker, Ariane G; Postma, Maarten J; Friedrich, Alexander W 2016-10-01 Infection prevention (IP) measures are vital to prevent (nosocomial) outbreaks. Financial evaluations of these are scarce. An incremental cost analysis for an academic IP unit was performed. On a yearly basis, we evaluated: IP measures; costs thereof; numbers of patients at risk for causing nosocomial outbreaks; predicted outbreak patients; and actual outbreak patients. IP costs rose on average yearly with €150,000; however, more IP actions were undertaken. Numbers of patients colonized with high-risk microorganisms increased. The trend of actual outbreak patients remained stable. Predicted prevented outbreak patients saved costs, leading to a positive return on investment of 1.94. This study shows that investments in IP can prevent outbreak cases, thereby saving enough money to earn back these investments. 45. Portable Ultraviolet Light Surface-Disinfecting Devices for Prevention of Hospital-Acquired Infections: A Health Technology Assessment PubMed Central Nikitovic-Jokic, Milica; Kabali, Conrad; Li, Chunmei; Higgins, Caroline 2018-01-01 Background Hospital-acquired infections (HAIs) are infections that patients contract while in the hospital that were neither present nor developing at the time of admission. In Canada an estimated 10% of adults with short-term hospitalization have HAIs. According to 2003 Canadian data, between 4% and 6% of these patients die from these infections. The most common HAIs in Ontario are caused by Clostridium difficile. The standard method of reducing and preventing these infections is decontamination of patient rooms through manual cleaning and disinfection. Several portable no-touch ultraviolet (UV) light systems have been proposed to supplement current hospital cleaning and disinfecting practices. Methods We searched for studies published from inception of UV disinfection technology to January 23, 2017. We compared portable UV surface-disinfecting devices used together with standard hospital room cleaning and disinfecting versus standard hospital cleaning and disinfecting alone. The primary outcome was HAI from C. difficile. Other outcomes were combined HAIs, colonization (i.e., carrying an infectious agent without exhibiting disease symptoms), and the HAI-associated mortality rate. We used Grading of Recommendations Assessment, Development, and Evaluation (GRADE) to rate the quality of evidence of included studies. We also performed a 5-year budget impact analysis from the hospital's perspective. This assessment was limited to portable devices and did not examine wall mounted devices, which are used in some hospitals. Results The database search for the clinical review yielded 10 peer-reviewed publications that met eligibility criteria. Three studies focused on mercury UV-C–based technology, seven on pulsed xenon UV technology. Findings were either inconsistent or produced very low-quality evidence using the GRADE rating system. The intervention was effective in reducing the rate of the composite outcome of HAIs (combined) and colonization (but quality of evidence 46.

The study data came from 5877 assessments distributed among selected practices. The results revealed the following adherence rates among the practices selected: 91.6% for recording the indication and permanence time of the CVC, 51.5% for adhering to the care and maintenance of the dressing at the CVC insertion site and its devices, 10.7% for hand hygiene practices while performing procedures related to the CVC, and 0.0% for the practices related to the insertion of the central venous catheter (CVC). The results demonstrate the need for further elaboration of strategies that ensure sustainable compliance practices for prevention and control BSI-ACVC in the institution being assessed. 47. Environmental scan of infection prevention and control practices for containment of hospital-acquired infectious disease outbreaks in acute care hospital settings across Canada.

However, the value and efficacy of ward closures remains uncertain. To understand the current practices and perceptions with respect to ward closure for hospital-acquired infectious disease outbreaks in acute care hospital settings across Canada. A Web-based environmental scan survey was developed by a team of infection prevention and control (IPC) experts and distributed to 235 IPC professionals at acute care sites across Canada. Data were analyzed using a mixed-methods approach of descriptive statistics and thematic analysis. A total of 110 completed responses showed that 70% of sites reported at least 1 outbreak during 2013, 44% of these sites reported the use of ward closure. Ward closure was considered an "appropriate," "sometimes appropriate," or "not appropriate" strategy to control outbreaks by 50%, 45%, and 5% of participants, respectively. System capacity issues and overall risk assessment were main factors influencing the decision to close hospital wards following an outbreak. Results suggest the use of ward closure for containment of hospital-acquired infectious disease outbreaks in Canadian acute care health settings is mixed, with outbreak control methods varying. The successful implementation of ward closure was dependent on overall support for the IPC team within hospital administration.

Cleaning Hospital Room Surfaces to Prevent Health Care–Associated Infections PubMed Central Han, Jennifer H.; Sullivan, Nancy; Leas, Brian F.; Pegues, David A.; Kaczmarek, Janice L.; Umscheid, Craig A. 2015-01-01 The cleaning of hard surfaces in hospital rooms is critical for reducing health care–associated infections. This review describes the evidence examining current methods of cleaning, disinfecting, and monitoring cleanliness of patient rooms, as well as contextual factors that may affect implementation and effectiveness. Key informants were interviewed, and a systematic search for publications since 1990 was done with the use of several bibliographic and gray literature resources. Studies examining surface contamination, colonization, or infection with Clostridium difficile, methicillin-resistant Staphylococcus aureus, or vancomycinresistant enterococci were included. Eighty studies were identified—76 primary studies and 4 systematic reviews. Forty-nine studies examined cleaning methods, 14 evaluated monitoring strategies, and 17 addressed challenges or facilitators to implementation. Only 5 studies were randomized, controlled trials, and surface contamination was the most commonly assessed outcome. Comparative effectiveness studies of disinfecting methods and monitoring strategies were uncommon. Future research should evaluate and compare newly emerging strategies, such as self-disinfecting coatings for disinfecting and adenosine triphosphate and ultraviolet/fluorescent surface markers for monitoring. Studies should also assess patient-centered outcomes, such as infection, when possible. Other challenges include identifying high-touch surfaces that confer the greatest risk for pathogen transmission; developing standard thresholds for defining cleanliness; and using methods to adjust for confounders, such as hand hygiene, when examining the effect of disinfecting methods.

PubMed Armour, Brian S; Ouyang, Lijing; Thibadeau, Judy; Grosse, Scott D; Campbell, Vincent A; Joseph, David 2009-07-01 The preventive health care needs of people with disabilities often go unmet, resulting in medical complications that may require hospitalization. Such complications could be due, in part, to difficulty accessing care or the quality of ambulatory care services received. To use hospitalizations for urinary tract infections (UTIs) as a marker of the potential quality of ambulatory care services received by people affected by spina bifida. MarketScan inpatient and outpatient medical claims data for 2000 through 2003 were used to identify hospitalizations for UTI, which is an ambulatory care sensitive condition, for people affected by spina bifida and to calculate inpatient discharge rates, average lengths of stay, and average medical care expenditures for such hospitalizations. People affected by spina bifida averaged 0.5 hospitalizations per year, and there were 22.8 inpatient admissions with UTI per 1000 persons with spina bifida during the period 2000-2003, in comparison to an average of 0.44 admission with UTI per 1000 persons for those without spina bifida. If the number of UTI hospitalizations among people affected by spina bifida were reduced by 50%, expenditures could be reduced by $4.4 million per 1000 patients. Consensus on the evaluation and management of bacteriuria could enhance clinical care and reduce the disparity in UTI discharge rates among people affected by spina bifida compared to those without spina bifida. National evidence-based guidelines are needed. 50. Decontamination of Hospital Surfaces With Multijet Cold Plasma: A Method to Enhance Infection Prevention and Control? PubMed Cahill, Orla J; Claro, Tânia; Cafolla, Attilio A; Stevens, Niall T; Daniels, Stephen; Humphreys, Hilary 2017-10-01 OBJECTIVE To evaluate the efficacy of a multijet cold-plasma system and its efficacy in decontaminating 2 surfaces commonly found in hospitals DESIGN An in vitro study of common causes of healthcare-acquired infection METHODS Log10 9 cultures of methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, extended spectrum β-lactamase-producing Escherichia coli, and Acinetobacter baumannii were applied to 5-cm2 sections of stainless steel and mattress. Human serum albumin (HSA) was used as a proxy marker for organic material, and atomic force microscopy (AFM) was used to study the impact on bacterial cell structure. The inoculated surfaces were exposed to a cold-airplasma-generating multijet prototype for 15, 20, 30, and 45 seconds. RESULTS After 45 seconds, at least 3 to 4 log reductions were achieved for all bacteria on the mattress, while 3 to 6 log reductions were observed on stainless steel. The presence of HSA had no appreciable effect on bacterial eradication. The surfaces with bacteria exposed to AFM showed significant morphological changes indicative of "etching" due to the action of highly charged ions produced by the plasma. CONCLUSION This multijet cold-plasma prototype has the potential to augment current environmental decontamination approaches but needs further evaluation in a clinical setting to confirm its effectiveness.

PubMed VanSteelandt, Amanda; Conly, John; Ghali, William; Mather, Charles 2015-01-01 The physical design of hospital wards is associated with transmission of pathogenic organisms and hospital-acquired infections. A novel hospital unit, the Medical Ward of the 21st Century (W21C), optimizes features for infection prevention and control practices. Ethnographic research on the W21C versus conventional hospital wards examined the experiential and behavioural elements of the different designs. Three recurring themes emerged regarding the design features on the W21C and included visual cues, 'having a place for things', and less sharing of spaces and materials. Observational data of healthcare worker practices demonstrated significantly higher compliance with hand hygiene opportunities on the W21C compared with older hospital units. These findings suggest how the physical design of a hospital ward may enhance infection prevention and control practices. 52. Infection prevention and control interventions in the first outbreak of methicillin-resistant Staphylococcus aureus infections in an equine hospital in Sweden PubMed Central 2012-01-01 Background The first outbreak of methicillin-resistant Staphylococcus aureus (MRSA) infection in horses in Sweden occurred in 2008 at the University Animal Hospital and highlighted the need for improved infection prevention and control. The present study describes interventions and infection prevention control in an equine hospital setting July 2008 - April 2010. Method This descriptive study of interventions is based on examination of policy documents, medical records, notes from meetings and cost estimates. MRSA cases were identified through clinical sampling and telephone enquiries about horses post-surgery. Prospective sampling in the hospital environment with culture for MRSA and genotyping of isolates by spa-typing and pulsed-field gel electrophoresis (PFGE) were performed. Results Interventions focused on interruption of indirect contact spread of MRSA between horses via staff and equipment and included: Temporary suspension of elective surgery; and identification and isolation of MRSA-infected horses; collaboration was initiated between authorities in animal and human public health, human medicine infection control and the veterinary hospital; extensive cleaning and disinfection was performed; basic hygiene and cleaning policies, staff training, equipment modification and interior renovation were implemented over seven months. Ten (11%) of 92 surfaces sampled between July 2008 and April 2010 tested positive for MRSA spa-type 011, seven of which were from the first of nine sampling occasions. PFGE typing showed the isolates to be the outbreak strain (9 of 10) or a closely related strain. Two new cases of MRSA infection occurred 14 and 19 months later, but had no proven connections to the outbreak cases. Conclusions Collaboration between relevant authorities and the veterinary hospital and formation of an infection control committee with an executive working group were required to move the intervention process forward.

Preventing ventriculostomy-related infections with antibiotic-impregnated drains in hospitals: a two-centre Dutch study. PubMed Verberk, J D M; Berkelbach van der Sprenkel, J W; Arts, M P; Dennesen, P J W; Bonten, M J M; van Mourik, M S M 2016-04-01 This observational cohort study assessed the effect of the introduction of antibiotic-impregnated external ventricular drains (AI-EVDs), as opposed to plain silicone EVDs, on the occurrence of ventriculostomy-related infections (VRIs) in two Dutch hospitals, with no other changes to their clinical practice. VRI was defined using the criteria of the Centers for Disease Control and Prevention, and with a culture-based definition. A propensity-score-adjusted competing risks survival analysis showed that introduction of AI-EVDs did not significantly decrease the risk of VRIs in routine care, nor affect the bacterial aetiology, even after adjustment for confounding and competing events.

Medical and health economic evaluation of prevention- and control measures related to MRSA infections or -colonisations at hospitals. PubMed Korczak, Dieter; Schöffmann, Christine 2010-03-16 Methicillin-resistant Staphylococcus aureus (MRSA) are dangerous agents of nosocomial infections. In 2007 the prevalence of MRSA is 20.3% in Germany (Oxacilline-resistance according to EUCAST-criteria [EUCAST = European Committee on Antimicrobial Susceptibility Testing]). Which measurements are effective in the prevention and control of MRSA-infections in the hospital?How effective are contact precautions, screening, decolonisation, education and surveillance?Which recommendations can be given to health care politics on the basis of cost-effectiveness studies?Have there been any adverse effects on patients and clinical staff?What kind of liability problems exist? Based on a systematic review of the literature studies are included which have been published in German or English language since 2004. 1,508 articles have been found. After having surveyed the full text, 33 medical, eight economic and four ethical/juridical studies are included for the Health Technology Assessment (HTA) report. The key result of the HTA report is that different measurements are effective in the prevention and control of MRSA-infections in hospitals, though the majority of the studies has a low quality. Effective are the conduction of differentiated screening measurements if they take into account the specific endemic situation, the use of antibiotic-control programs and the introduction and control of hygienic measurements. The break even point of preventive and control measurements cannot be defined because the study results differ too much. In the future it has to be more considered that MRSA-infections and contact precautions lead to a psycho-social strain for patients. It is hardly possible to describe causal efficacies because in the majority of the studies confounders are not sufficiently considered. In many cases bundles of measurements have been established but not analyzed individually. The internal and external validity of the studies is too weak to evaluate single interventions 56. Strategies to promote infection prevention and control in acute care hospitals with the help of infection control link nurses: A systematic literature review. PubMed Peter, Daniel; Meng, Michael; Kugler, Christiane; Mattner, Frauke 2018-02-01 Infection control link nurses (ICLNs) are important backup personnel for the prevention and control of infections in hospitals. To identify facilitators and barriers for the implementation of and long-term collaboration with ICLNs. We conducted a systematic literature review, following the preferred reporting items for systematic reviews and metaanalyses guidelines. Inclusion criteria were defined as description of de novo implementation of an ICLN system, strengthening of an existing ICLN system, or analysis of an ICLN system. In 10 publications, facilitators and barriers were identified for mode of selection of ICLN candidates, characteristics and responsibilities of ICLNs, composition of a training curriculum, educational strategies, and external influencing factors. Experienced nurses with an interest in infection control seemed appropriate candidates. The importance of psychological skills in addition to technical knowledge was emphasized. A clear definition of responsibilities was important. Viable tasks for ICLNs included surveillance and teaching activities and the implementation of prevention measures. Ongoing teaching was superior to a single course. Management support was pivotal for success. Research on ICLNs is scarce. The potential to decrease health care-associated infections with the help of ICLNs has been demonstrated. The training in psychological skills in addition to technical knowledge deserves more attention. Copyright © 2018 Association for Professionals in Infection Control and Epidemiology, Inc.

PubMed Duerink, D O; Farida, H; Nagelkerke, N J D; Wahyono, H; Keuter, M; Lestari, E S; Hadi, U; Van den Broek, P J 2006-09-01 Standard precautions can prevent transmission of micro-organisms. This study investigated hand hygiene, handling of needles and use of personal protective equipment in an Indonesian teaching hospital, and performed a multi-faceted intervention study to improve compliance. An intervention was performed in an internal medicine ward and a paediatric ward, consisting of development of a protocol for standard precautions, installation of washstands, educational activities and performance feedback. Before, during and after the intervention, observers monitored compliance with hand hygiene, safe handling of needles and use of gloves, gowns and masks. A gynaecology ward served as the control. Unobtrusive observations were performed to check for an influence of the observers on the overt observations. In total, 7,160 activities were observed. Compliance with hand hygiene increased from 46% to 77% in the internal medicine ward and from 22% to 62% in the paediatric ward. Before the intervention, no safe recapping of needles was recorded in either ward. After the intervention, 20% of needles were recapped safely. Inappropriate gown use decreased in the internal medicine ward. There were no significant changes in use of gloves and masks. There may have been an effect of the overt observations in the paediatric ward, but there was no effect in the internal medicine ward. There were no significant changes in the control ward, except for a decrease in the use of gloves. In conclusion, compliance with hand hygiene procedures improved significantly due to an intervention project focused on education and improved facilities. Compliance with safe handling of needles improved slightly due to introduction of the one-handed method for safe recapping of used needles. 58. Compliance with the National Palestinian Infection Prevention and Control Protocol at Governmental Paediatric Hospitals in Gaza Governorates PubMed Central Eljedi, Ashraf; Dalo, Shareef 2014-01-01 Objectives: Nosocomial infections are a significant burden for both patients and the healthcare system. For this reason, infection prevention and control (IPC) practices are extremely important. The Palestinian Ministry of Health adopted the national IPC Protocol in 2004. This study aimed to assess the compliance of healthcare providers (HCPs) with the Protocol in three governmental paediatric hospitals in Gaza governorates. Methods: This descriptive cross-sectional study was conducted from February to November 2010. Data were collected from a sample of doctors, nurses and physiotherapists (N = 334) using a self-administered questionnaire and observation checklists to record HCP practices and assess the hospital environment. Results: The response rate was 92%. The most important reasons for non-compliance with the IPC Protocol were the absence of an education programme (61.5%), lack of knowledge (52.4%) and the scarcity of required supplies (46.9%). Only 2.3% of respondents had a copy of the IPC Protocol, while 65.8% did not know of its

existence. Only 16.9% had participated in training sessions regarding general IPC practices. The observation checklist regarding HCP practices revealed low levels of compliance in hand washing (45.9%), wearing gloves (40.7%) and using antiseptics/disinfectants (49.16%). The health facilities checklist indicated that there was a lack of certain essential equipment and materials, such as covered waste containers and heavy-duty gloves. Conclusion: Due to the lack of HPC knowledge, the authors recommend that the IPC Protocol be made available in all hospitals. In addition, a qualified team should implement intensive IPC education and training programmes and facilities should provide the required equipment and materials. PMID:25097774 59.

The association of hospital prevention processes and patient risk factors with the risk of Clostridium difficile infection: a population-based cohort study. PubMed Daneman, N; Guttmann, A; Wang, X; Ma, X; Gibson, D; Stukel, T A 2015-07-01 Clostridium difficile is the most common cause of healthcare-acquired infection; the real-world impacts of some proposed C. difficile prevention processes are unknown. We conducted a population-based retrospective cohort study of all patients admitted to acute care hospitals between April 2011 and March 2012 in Ontario, Canada. Hospital prevention practices were determined by survey of infection control programmes; responses were linked to patient-level risk factors and C. difficile outcomes in Ontario administrative databases. Multivariable generalised estimating equation (GEE) regression models were used to assess the impact of selected understudied hospital prevention processes on the patient-level risk of C. difficile infection, accounting for patient risk factors, baseline C. difficile rates and structural hospital characteristics. C. difficile infections complicated 2341 of 653 896 admissions (3.6 per 1000 admissions). Implementation of the selected C. difficile prevention practices was variable across the 159 hospitals with isolation of all patients at onset of diarrhoea reported by 43 (27%), auditing of antibiotic stewardship compliance by 26 (16%), auditing of cleaning practices by 115 (72%), on-site diagnostic testing by 74 (47%), vancomycin as first-line treatment by 24 (15%) and reporting rates to senior leadership by 52 (33%). None of these processes were associated with a significantly reduced risk of C. difficile after adjustment for baseline C. difficile rates, structural hospital characteristics and patient-level factors. Patient-level factors were strongly associated with C. difficile risk, including age, comorbidities, non-elective and medical admissions. In the largest study to date, selected hospital prevention strategies were not associated with a statistically significant reduction in patients' risk of C. difficile infection. These prevention strategies have either limited effectiveness or were ineffectively implemented during the study « 1 2 3 4 5 » « 2 3 4 5 6 » 61. Effects of a catheter-associated urinary tract infection prevention campaign on infection rate, catheter utilization, and health care workers' perspective at a community safety net hospital. PubMed Gray, Dorinne; Nussle, Richard; Cruz, Abner; Kane, Gail; Toomey, Michael; Bay, Curtis; Ostovar, Gholamabbas Amin 2016-01-01 Preventing catheter-associated urinary tract infections is in the forefront of health care quality. However, nurse and physician engagement is a common barrier in infection prevention efforts. After implementation of a multidisciplinary catheter-associated urinary tract infection (CAUTI) prevention campaign, we studied the impact of our campaign and showed its association with reducing the CAUTI rate and catheter utilization and the positive effect on health care workers' engagement and perspectives. CAUTI prevention campaigns can lead to lower infection rates and change health care workers' perspective. Copyright © 2016 Association for Professionals in Infection Control and Epidemiology, Inc.

Addressing Infection Prevention and Control in the First U.S. Community Hospital to Care for Patients With Ebola Virus Disease: Context for National Recommendations and Future Strategies. PubMed Cummings, Kristin J; Choi, Mary J; Esswein, Eric J; de Perio, Marie A; Harney, Joshua M; Chung, Wendy M; Lakey, David L; Liddell, Allison M; Rollin, Pierre E 2016-05-10 Health care personnel (HCP) caring for patients with Ebola virus disease (EVD) are at increased risk for infection with the virus. In 2014, a Texas hospital became the first U.S. community hospital to care for a patient with EVD; 2 nurses were infected while providing care. This article describes infection control measures developed to strengthen the hospital's capacity to safely diagnose and treat patients with EVD. After admission of the first patient with EVD, a multidisciplinary team from the Centers for Disease Control and Prevention (CDC) joined the hospital's infection preventionists to implement a system of occupational safety and health controls for direct patient care, handling of clinical specimens, and managing regulated medical waste. Existing engineering and administrative controls were strengthened. The personal protective equipment (PPE) ensemble was standardized, HCP were trained on donning and doffing PPE, and a system of trained observers supervising PPE donning and doffing was implemented. Caring for patients with EVD placed substantial demands on a community hospital. The experiences of the authors and others informed national policies for the care of patients with EVD and protection of HCP, including new guidance for PPE, a rapid system for deploying CDC staff to assist hospitals ("Ebola Response Team"), and a framework for a tiered approach to hospital preparedness. The designation of regional Ebola treatment centers and the establishment of the National Ebola Training and Education Center address the need for HCP to be prepared to safely care for patients with EVD and other high-consequence emerging infectious diseases. 64. Prevention and control of catheter-associated urinary tract infections - implementation of the recommendations of the Commission for Hospital Hygiene and Infection Prevention (KRINKO) in nursing homes for the elderly in Frankfurt am Main, Germany. PubMed Heudorf, Ursel; Gasteyer, Stefanie; Müller, Maria; Samoiski, Yvonne; Serra, Nicole; Westphal, Tim 2016-01-01 Urinary tract infections range among the most frequent infections not only in hospital patients but also in residents of long-term care facilities for the elderly. Urinary catheters are the greatest risk factor for urinary tract infections. In the guidance paper on the "prevention of infections in nursing homes" (2005) as well as in the updated recommendations for the "prevention and control of catheter-associated urinary tract infections" (2015), the Commission for Hospital Hygiene and Infection Prevention (KRINKO) has recommended adequate preventive measures. In 2015, the implementation of these KRINKO recommendations was investigated. All of Frankfurt's 40 nursing homes were evaluated using a checklist based on the KRINKO recommendations. The evaluation included assessing the availability of operating instructions, appropriate indications for the placement of catheters etc. Age, sex and duration of catheterization, as well as current and previous infections within the past 6 months were documented for every resident with a catheter. In 35 (87.5%) of the nursing homes, operating instructions for the handling of urinary tract catheters were available. The decision as to whether a catheter is indicated is made by physicians, while its placement is often delegated to the nursing service. Typically, silicon catheters are used. In three-quarters of the nursing homes, regular intervals of 4-6 weeks for changing catheters were reported. On the respective survey day, 7.3% of the residents were catheterized. On the survey day, 3.6% (4.2%) and in the previous 6 months a total of 28% (28.9%) of the residents had a urinary tract infection (prevalence of antibiotic therapy in parentheses). Ciprofloxacin was used most often followed by cefuroxime and cotrimoxazole. In the current evaluation, fewer nursing home residents were catheterized than in previous years and the rate of urinary tract infections was low. This indicates an increasingly cautious and apparently appropriate 65. Tuberculosis prevention versus hospitalization: taxpayers save with prevention. PubMed Marks, Suzanne Marie; Taylor, Zachary; Miller, Bess I 2002-08-01 This study describes who pays for inpatient tuberculosis (TB) care and factors associated with payer source. The authors analyzed TB hospitalization costs for a prospective cohort of active TB patients at 10 U.S. sites. Private insurance paid for 9 percent and private hospitals for 6 percent of TB hospitalization costs. Public sources (federal, state, and local governments and public hospitals) paid more than 85 percent of TB hospitalization costs. Preventive services (treatment for latent TB infection; housing, food, and social work for homeless persons; substance abuse treatment for substance abusers; and antiretroviral medication for HIV-infected persons) targeted to those at high risk for TB hospitalization could save taxpayers between $4 million and $118 million. Since public resources are used to pay nearly all the costs of late-stage TB care, the public sector could save by shifting resources currently used for inpatient care to target preventive services to persons at high risk for TB hospitalization. 66.

PubMed Heudorf, U; Exner, M 2011-03-01 In 2009, the new directive of the German Commission for Hospital Hygiene and Infection Prevention (Kommission für Krankenhaushygiene und Infektionsprävention, KRINKO) entitled Human and Organizational Requirements for the Prevention of Nosocomial Infections was published, including detailed information on the needs of hygiene professionals in hospital settings. Compared to the needs calculated according to the above policy, the current staff hygiene health professionals (HHPs) in the hospitals of Frankfurt am Main (Frankfurt/M), Germany, was on average 27.6%: 36% in the large hospitals (>600 beds), 21.6% in medium hospitals (300-600 beds), and 19.8% in small hospitals ( 0.05). In conclusion, delay initiation of antiviral therapy and medical complications (pneumonia and rhinosinusitis) were more common among hospitalized children with influenza B than outpatient children with influenza B in the studied population. « 9 10 11 12 13 » « 10 11 12 13 14 » 221. Recently published papers: A review of novel strategies in the prevention of hospital-acquired infections, the ability of intensivists to perform echocardiography, and the benefit of polymyxin B haemoperfusion in abdominal sepsis PubMed Central 2009-01-01 Chlorhexidine bed baths seem to reduce the incidence of methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococcus detected by surveillance cultures. There is also some evidence on the benefit of chlorhexidine mouthwashes in the prevention of ventilator-associated pneumonias. Acid-suppressing drugs increase the incidence of hospitalacquired pneumonias in non-intensive care unit patients, although this association has not been shown in the intensive care setting. Intensivists can be trained to perform basic echocardiography in a short period of time, but their errors could lead to incorrect changes in management. Polymyxin B haemoperfusion was shown in interim analysis to improve patients with abdominal sepsis to such an extent that the EUPHAS randomised controlled trial was halted on ethical grounds, although other authors have criticised this decision. 222.

Role of disinfection in the Infection Prevention Multibarrier System. PubMed Kramer, Axel 2007-09-13 The role of disinfection in infection prevention has been analyzed over the past 50 years both in the form of benefit-risk evaluations as well as in an epidemiological sense. This has served as the basis for not only national and international guidelines and recommendations, but has also created the legal and normative framework for regulation of infection control (and hence of disinfection) in numerous and acts and ordinances. Likewise, today the efficacy of disinfection measures, user safety and environmental compatibility in line with the state of the art are assured. Compliance as regards the conductance of disinfection measures has increased accordingly. The user is able to select and correctly employ the disinfectant most suited to the intended disinfection procedure. The quality of the apparatus used has vastly improved since the coming into force of the German Medical Devices Act (MPG). And finally the preconditions for conductance of disinfection have become so matter of fact that it is easy to forget just what progress has been made here. This applies e.g. to the facilities now available for hand hygiene, for decontamination of instruments, laundry and bedpans with washer-disinfectors as well as for surface disinfection and drinking water disinfection. But it is the human being who continues to pose the greatest risk. Risk awareness does not always result in proper action being taken: it is hard to really grasp something that one cannot experience. As such, hand disinfection is often dispensed with, and without any sense of having done something wrong, the debate about the evidence of the usefulness of floor disinfection continues, and often medical practitioners fail to resort to exclusive automated decontamination of medical devices because of the costs incurred. Hospitals, nursing homes and rehabilitation establishments are obliged to set up a quality management system, and to continue developing this. This calls for a quality assurance system 224. Long-term effect of infection prevention practices and case mix on cesarean surgical site infections.

A multivariable autoregressive integrated moving average model was used to perform time series analysis on a 96-month retrospective cohort of patients who underwent cesarean delivery (January 2003-December 2010) in a U.S. tertiary care hospital. We identified 8,668 women who underwent cesarean delivery. Median age was 26 years (range 12-53 years), 3,093 (35.7%) of patients had body mass indexes (BMIs) of 35 or greater, 2,561 (29.5%) were of white race, and 303 (3.5%) had a surgical site infection. Over the study period, there was a significant increase in the proportion of patients who underwent cesarean delivery who had BMIs of 35 or higher, hypertension or mild preeclampsia, and severe preeclampsia or eclampsia. A nonseasonal autoregressive integrated moving average model with a linear trend and no autocorrelation was identified. In the multivariable autoregressive integrated moving average model of postcesarean surgical site infections, implementation of a policy to administer prophylactic antibiotics within 1 hour before incision, instead of at the time of cord clamp, led to a 48% reduction in cesarean delivery surgical site infections (Δ=-5.4 surgical site infections per 100 cesarean deliveries; P 80% of transvaginal ultrasound probe handles are contaminated with disease causing pathogens since handle disinfection is omitted from standard reprocessing protocols.

Diagnosis, Treatment, and Prevention of Urinary Tract Infection. PubMed Pietrucha-Dilanchian, Paula; Hooton, Thomas M 2016-12-01 UTI may involve the lower or upper urinary tract and may be uncomplicated or complicated. The emphasis of this chapter is uncomplicated UTI. The diagnosis of uncomplicated cystitis (bladder infection) and pyelonephritis (kidney infection) is usually easily made based on the clinical presentation, whereas the diagnosis in patients with complicated UTI is often more complex. Thus uncomplicated cystitis is usually manifested by dysuria, frequency and/or urgency without fever, and pyelonephritis is usually manifested by fever and back pain/costovertebral angle tenderness. However, pyuria is usually present with UTI, regardless of location, and its absence suggests that another condition may be causing the patient's symptoms. Treatment of cystitis is usually straightforward with one of several effective short-course antimicrobial regimens, although antimicrobial resistance continues to increase and can complicate treatment choices in certain areas. Likewise, antimicrobial resistance has complicated our management of uncomplicated pyelonephritis since resistance of uropathogens to the fluoroquinolone class, the mainstay of oral treatment for pyelonephritis, is increasing worldwide, and some of the other agents used for cystitis are not recommended for pyelonephritis due to low tissue levels. The goal of prevention of recurrent cystitis is to minimize the use of antimicrobials and there are several research efforts in progress to develop effective and safe antimicrobial-sparing preventive approaches for this common condition. 462. Disability Adjusted Life Year (DALY) of Central-Line Bloodstream Infection (CLABSI) in a University Hospital in a Developing Country, Brazil. PubMed da Rocha, Jaqueline Abel; do Valle, Fernanda Moreth; da Silva, Natalia Chilinque Zambão; Nunes Silva, Ana Sheila Duarte; Vaz, Suzana Dos Santos; de Araújo, Wildo Navegantes; Martins, Ianick Souto 2017-05-01 Central-line bloodstream infection (CLABSI) increases hospital mortality. A cohort study was conducted in a Brazilian hospital to estimate the disability-adjusted life year (DALY) of CLABSI using modified World Health Organization (WHO) methodology. CLABSI DALY was 20.44 per 1,000 inpatients, most were the result of premature death (20.42 per 1,000 inpatients). DALY can be useful to guide and measure the impact of healthcare infection prevention. Infect Control Hosp Epidemiol 2017;38:606-609. 463. Cost-effectiveness of strategies to prevent methicillin-resistant Staphylococcus aureus transmission and infection in an intensive care unit. PubMed Gidengil, Courtney A; Gay, Charlene; Huang, Susan S; Platt, Richard; Yokoe, Deborah; Lee, Grace M 2015-01-01 OBJECTIVE To create a national policy model to evaluate the projected cost-effectiveness of multiple hospital-based strategies to prevent methicillin-resistant Staphylococcus aureus (MRSA) transmission and infection. DESIGN Cost-effectiveness analysis using a Markov microsimulation model that simulates the natural history of MRSA acquisition and infection. PATIENTS AND SETTING Hypothetical cohort of 10,000 adult patients admitted to a US intensive care unit. METHODS We compared 7 strategies to standard precautions using a hospital perspective: (1) active surveillance cultures; (2) active surveillance cultures plus selective decolonization; (3) universal contact precautions (UCP); (4) universal chlorhexidine gluconate baths; (5) universal decolonization; (6) UCP + chlorhexidine gluconate baths; and (7) UCP+decolonization. For each strategy, both efficacy and compliance were considered. Outcomes of interest were: (1) MRSA colonization averted; (2) MRSA infection averted; (3) incremental cost per colonization averted; (4) incremental cost per infection averted. RESULTS A total of 1989 cases of colonization and 544 MRSA invasive infections occurred under standard precautions per 10,000 patients. Universal decolonization was the least expensive strategy and was more effective compared with all strategies except UCP+decolonization and UCP+chlorhexidine gluconate. UCP+decolonization was more effective than universal decolonization but would cost $2469 per colonization averted and $9007 per infection averted. If MRSA colonization prevalence decreases from 12% to 5%, active surveillance cultures plus selective decolonization becomes the least expensive strategy. CONCLUSIONS Universal decolonization is cost-saving, preventing 44% of cases of MRSA colonization and 45% of cases of MRSA infection. Our model provides useful guidance for decision makers choosing between multiple available hospital-based strategies to prevent MRSA transmission. 464. Hospital acquired blood stream infection as an adverse outcome for patients admitted to hospital with other principle diagnosis. PubMed Al-Hazmi, Hamdan H; Al-Zahrani, Tariq; Elmalky, Ahmed M 2014-11-01 Hospital acquired infections (HAI) have emerged as an important public health problem and are a leading cause of morbidity and mortality worldwide. They affect both developed and resource-poor countries and constitute a significant burden both for the patient and for the health care system. Specific objectives in this study are assessment of HAI rate among patients admitted with other principle diagnosis, to identifying the causative agents of hospital acquired infections and to identify some possible risk factors associated with each type of infection, both health related and non-health related. The study was done on selected diagnosis groups during year 2010. The infections were found among 250 patients (43.6% males) have been exposed to episodes of infections. Median age of patients was 56. Data were abstracted from the archived patients' files in medical record department using the annually infection control log-book prepared by the infection control department. The Data collected were demographic information about the patients (age and sex), clinical condition (diagnosis and the length of hospital stay) and possible risk factors for infection as smoking, diabetes mellitus, hypertension and exposure to invasive devices or exposure to surgical procedures. Liver diseases 22.8%, cardiac diseases 22.8%, Gastro-Intestinal System diseases 20%, urinary system diseases 13.6%, and endocrinal disorder 13.6% Prostate gland diseases 7.2%. Episodes of infections caused by 9 types of organisms divided into 47.2% for blood stream infection and 52.8% for other types. 66% acquired blood stream infection were exposed to central venous line. Most common type of HAIs was blood stream infections. Liver, cardiac diseases and gastro-intestinal diseased patients show more proportion of HAIs while urinary system and prostate disease patients show less proportion of HAIs. Gram negative bacilli were the most common organisms found in our study (60%). 465. Risk factors and epidemiology of Acinetobacter baumannii infections in a university hospital in Northern Italy: A case-control study. PubMed Ardoino, I; Zangirolami, F; Iemmi, D; Lanzoni, M; Cargnelutti, M; Biganzoli, E; Castaldi, S 2016-12-01 Acinetobacter baumannii has emerged as a major cause of outbreaks of hospital-associated infections with increased morbidity and mortality among those affected. We performed a 1:1 matched case-control study involving 68 cases in a teaching hospital in Northern Italy. Risk factors included general health conditions, comorbidities, diagnostic and therapeutic procedures, and antibiotic therapies. A multiple correspondence analysis (MCA) was performed to highlight possible association patterns among risk factors. After this, a conditional logistic regression model was applied. The combined results of the MCA and univariate regression models suggest that invasive procedures performed before intensive care unit admission, in particular bronchoscopy (odds ratio, 48.06) and oxygen therapy (odds ratio, 2.11), are associated with development of an infection. Malnutrition or obesity, lack of selfsufficiency, and severe liver diseases also proved to be significantly associated with infection. When analyzing antibiotic therapies, both the number of molecules administered and duration of therapy were significantly associated. Early recognition of patients at high risk, environmental hygiene control measures, appropriate antibiotic prescriptions, especially regarding carbapenems, and high-quality training of health care workers in all hospital departments are all key aspects for prevention and control of Acinetobacter infection. Further studies are needed to investigate the role of antibiotics on microbial competition dynamics in relation to multidrug-resistant outbreaks.

Progression from new methicillin-resistant Staphylococcus aureus colonisation to infection: an observational study in a hospital cohort. PubMed Balm, Michelle N D; Lover, Andrew A; Salmon, Sharon; Tambyah, Paul A; Fisher, Dale A 2013-10-22 Patients newly colonised with methicillin-resistant Staphylococcus aureus (MRSA) are at higher risk of clinical MRSA infection. At present, there are limited data on the duration or magnitude of this risk in a hospital population with a known time of MRSA acquisition. A retrospective cohort study of 909 adult patients known to have newly identified MRSA colonisation during admission to National University Hospital, Singapore between 1 July 2007 and 30 June 2011 was undertaken. Patients were excluded if they had history of previous MRSA colonisation or infection, or if they had been a hospital inpatient in the preceding 12 months. Data were collected on the development of MRSA infection requiring hospitalisation up to 30 June 2012. Of 840 patients newly colonised with MRSA as identified on active surveillance and not clinical specimens, 546 were men (65.0%) and the median age was 65 years (range 18-103 years). Median follow up was 24 months (range 0 -64 months, 85.1% followed >6 months). Clinical infection occurred in 121 patients (14.4%) with median time to infection of 22 days (95% CI 14-31). Overall 71.9% (87/121) of infected patients developed infection within 60 days of the date MRSA colonisation was detected. However, 17/121 patients (14.0%) developed clinical infection more than six months after documented MRSA acquisition. The most common sites of clinical infection were skin and soft tissue (49/121, 40.5%, 95% CI 31.7-49.8), respiratory tract (37/121, 30.6%, 95% CI 22.5-39.6) and bone and joint infections (14/121, 11.6%, 95% CI 6.5-18.7). Thirteen patients (13/121, 10.7%, 95% CI 5.8-17.7) had bacteraemias, of which six (5.0% 95% CI 1.8-10.5) were primary and seven (5.7%, 95% CI 2.3-11.6) were secondary to infection at other sites. Crude mortality at 30 days and six months was higher in patients with MRSA infection than colonisation alone (aOR 5.49, 95% CI 2.75-10.95, p
