Clinical impact of vancomycin-resistant enterococci colonization in nonliver solid organ transplantation and its implications for infection control strategies: A single-center, 10-year retrospective study. Transpl Infect Dis 2021; 23:e13747. [PMID: 34674357 DOI: 10.1111/tid.13747] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Revised: 09/30/2021] [Accepted: 10/02/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND Vancomycin-resistant enterococci (VRE) colonization in nonliver solid organ transplantation (SOT) is poorly defined. Infection control management of these patients is influenced by the association of VRE with adverse outcomes in liver transplantation. This study examines the frequency and clinical impact of VRE colonization specifically on nonliver SOT patients and discusses implications for nosocomial VRE control. METHODS We retrospectively reviewed all nonliver SOT patients at a single transplant center from 2005 to 2015. We determined colonization rates in the peritransplant period and the rate of VRE infections. The association between VRE colonization with 90-day mortality and other clinical outcomes was examined. RESULTS There were 1786 nonliver SOTs from 2005 to 2015, with 81 (4.6%) colonized with VRE in the peritransplantation period. The colonization prevalence varied by organ type: 45 of 423 lung (10.6%), 12 of 352 heart (3.4%), one of 18 heart-lung (5.6%), 20 of 884 kidney (2.3%), three of 63 kidney-pancreas (4.8%), zero of 11 pancreas, zero of five small bowel, and zero of 11 multivisceral. Peritransplant VRE colonization was not associated with 90-day mortality odds ratio = 2.35 (95% CI = 0.53, 10.29) and adjusted odds ratio = 1.52 (95% CI = 0.34, 6.88). In the multivariable logistic regression, there was no association with mortality at 1 year or 5 years, hospital length of stay, rehospitalization, or days alive out of hospital. There were 14 inpatient VRE infections up to 1 year after transplantation. CONCLUSION Nonliver SOT patients have lower rates of VRE colonization than liver SOT, and colonization was not associated with increased adverse clinical outcomes. Although infection control strategies for VRE in hospital remain controversial, nonliver SOT should be considered among typical hospitalized patients when designing strategies for prevention.

Abstract
BACKGROUND Use of isolation precautions (IP) may represent a trade-off between reduced transmission of infectious pathogens and reduced patient satisfaction with their care. OBJECTIVE To perform a systematic literature review and meta-analysis to identify if and how IPs impact patients' care experiences. DATA SOURCES Medline, ClinicalTrials.gov, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, PsychInfo, HSRProj and Cochrane Library databases. STUDY ELIGIBILITY CRITERIA Interventional and observational studies published January 1990 to May 2019 were eligible for inclusion. PARTICIPANTS Patients admitted to an acute-care facility. INTERVENTIONS IPs versus no IPs. METHODS Six reviewers screened titles, abstracts and full text. Experience of care reported by patients using the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey was assessed as the outcome for the meta-analysis. Pooled odds ratios were calculated using the random-effects model. Heterogeneity was assessed using the I2 value. RESULTS After screening 7073 titles and abstracts, 15 independent studies were included in the review. Pooling of unadjusted estimates from the HCAHPS survey demonstrated that IP patients were less likely to give top scores on questions pertaining to respect, communication, receiving assistance and cleanliness compared to the no-IP patients. Patients under IP with longer length of stay appeared to have more negative experiences with the care received during their stay compared to no IP. CONCLUSIONS Patients under IP were more likely to be dissatisfied with several aspects of patient care compared to patients not under IP. It is crucial to educate patients and healthcare workers in order to balance successful implementation of IP and patient care experiences, particularly in healthcare settings where it may be beneficial.

Abstract
PURPOSE The purpose of this paper, a point prevalence study, is to quantify the incidence of isolation and identify the type of communicable diseases in isolation. The paper evaluates isolation precaution communication, availability of personal protective equipment (PPE) as well as other equipment necessary for maintaining isolation precautions. DESIGN/METHODOLOGY/APPROACH A standardised audit tool was developed in accordance with the National Standards for the Prevention and Control of Healthcare Associated Infections (May 2009). Data were collected from 14 March 2017 to 16 March 2017, through observation of occupied isolation rooms in an academic hospital in Dublin, Ireland. The data were subsequently used for additional analysis and discussion. FINDINGS In total, 14 per cent (125/869) of the total inpatient population was isolated at the time of the study. The most common isolation precaution was contact precautions (96.0 per cent). In all, 88 per cent of known contact precautions were due to multi-drug resistant organisms. Furthermore, 96 per cent of patients requiring isolation were isolated, 92.0 per cent of rooms had signage, 90.8 per cent had appropriate signs and 93.0 per cent of rooms had PPE available. Finally, 31 per cent of rooms had patient-dedicated and single-use equipment and 2.4 per cent had alcohol wipes available. PRACTICAL IMPLICATIONS The audit tool can be used to identify key areas of noncompliance associated with isolation and inform continuous improvement and education. ORIGINALITY/VALUE Currently, the rate of isolation is unknown in Ireland and standard guidelines are not established for the evaluation of isolation rooms. This audit tool can be used as an assessment for isolation room compliance.

Abstract
Multi-resistant bacteria pose an increasing and significant challenge to public health. Isolation precautions in patients with multi-drug-resistant bacteria and other communicable infectious agents can be associated with adverse effects. Although few would dispute the need for such practices in preventing the spread of transmissible infections, patients' perspectives of isolation suggest that the imposed environment creates barriers to their physical, social and emotional needs. This article reviews the literature to uncover any reliable evidence supporting the assertion that the experience of isolation in healthcare settings impacts adversely on patient wellbeing. Database searches identified 25 relevant papers published between 1990 and 2017. A number of studies claimed to have uncovered an association between negative patient experiences and isolation.

Abstract
The notion of 'isolation' in infectious diseases refers to the possibility of people known or suspected to be infected from the wider population, and has historically been used to control and prevent the spread of infectious diseases. Isolation practices in healthcare settings evolved over the 20th century resulting in a focus on the disruption of known routes of potential transmission. There was renewed attention to infection prevention and control (IPC) in the UK at the turn of the 20th century after high-profile reports acknowledged the importance of IPC as a key indicator of high-quality clinical care, and the impact of healthcare-acquired infections. There has been a shift away from isolation wards towards isolation in single rooms on general wards. For infections that are spread by the airborne, droplet or contact routes, placing the patient in single-room isolation is considered to be an important component of transmission-based precautions (TBPs). However, in practice isolation is complex and a number of challenges are involved in implementing IPC procedures.

Abstract
Background Isolation precautions in patients with multi-drug-resistant bacteria and other communicable infectious agents can be associated with adverse effects. Patients' perspectives of isolation suggest that the imposed environment and procedures create barriers to their physical, social and emotional needs. Aims The purpose of this paper is to review the literature to uncover any reliable evidence supporting the assertion that stigma is a significant characteristic of the experience of source isolation in healthcare settings. Methods The methodological framework of Arksey and O'Malley was applied to this review. A total of 14 papers identified from 189 abstracts screened were included in the review. Results The research reviewed suggests a clear association between stigmatisation and isolation in which stigma does have a direct negative effect on patients placed in hospital isolation. None of the studies found evidence to the contrary. Conclusions The implications of this literature review for policy-makers and healthcare professionals suggest that when isolation or other forms of constraint are implemented and in use, patients must be provided with strengthened forms of support, including social and emotional support, and given access to healthcare of optimal quality to prevent the associated adverse effects of isolation as much as possible.

Abstract
BACKGROUND Healthcare associated infection (HCAI) is a major cause of morbidity and mortality. In recent years, there have been high profile successes in infection prevention control (IPC), such as the dramatic reductions in methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections (which is viewed as one proxy indicator of overall harm) and Clostridium difficile in the UK. Nevertheless, HCAI remains a costly burden to health services, a source of concern to patients and the public and at present, is receiving priority from policy makers as it contributes to the global threat of antimicrobial resistance. METHODS The study involves qualitative case studies within isolation settings at two National Health Service (NHS) district general hospitals (DGHs) in Wales, in the UK. The 18-month study incorporates Manchester Patient Safety Framework (MaPSaF) workshops with health workers and other hospital staff, in depth interviews with patients and their relative / informal carer, health workers and hospital staff, and periods of hospital ward observation. DISCUSSION The present study aims to investigate the ways in which engagement of health workers with IPC strategies and principles, shape and inform organisational patient safety culture within the context of isolation in surgical, medical and admission hospital settings; and vice-versa. We want to understand the meaning of IPC 'ownership' for health workers; the ways in which IPC is promoted, how IPC teams operate as new challenges arise, how their effectiveness is assessed and the positioning of IPC within the broader context of organisational patient safety culture, within hospital isolation settings.

Abstract
BACKGROUND Several single-center studies have suggested that eliminating contact precautions (CPs) for methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) control in nonoutbreak settings has no impact on infection rates. We performed a systematic literature review and meta-analysis on the impact of discontinuing contact precautions in the acute care setting. METHODS We searched PubMed, CINAHL, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, and Embase through December 2016 for studies evaluating discontinuation of contact precautions for multidrug-resistant organisms. We used random-effect models to obtain pooled risk ratio estimates. Heterogeneity was evaluated with I2 estimation and the Cochran Q statistic. Pooled risk ratios for MRSA and VRE were assessed separately. RESULTS Fourteen studies met inclusion criteria and were included in the final review. Six studies discontinued CPs for both MRSA and VRE, 3 for MRSA only, 2 for VRE only, 2 for extended-spectrum β-lactamase-producing Escherichia coli, and 1 for Clostridium difficile infection. When study results were pooled, there was a trend toward reduction of MRSA infection after discontinuing CPs (pooled risk ratio, 0.84; 95% confidence interval, 0.70-1.02; P = .07) and a statistically significant reduction in VRE infection (pooled risk ratio, 0.82; 95% confidence interval, 0.72-0.94; P = .005). CONCLUSIONS Discontinuation of CPs for MRSA and VRE has not been associated with increased infection rates.

Abstract
BACKGROUND Recent studies have shown that using no-touch disinfection technologies (ie, ultraviolet light [UVL] or hydrogen peroxide vapor [HPV] systems) can limit the transmission of nosocomial pathogens and prevent healthcare-associated infections (HAIs). To investigate these findings further, we performed a systematic literature review and meta-analysis on the impact of no-touch disinfection methods to decrease HAIs. METHODS We searched PubMed, CINAHL, CDSR, DARE and EMBASE through April 2017 for studies evaluating no-touch disinfection technology and the nosocomial infection rates for Clostridium difficile, methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and other multidrug-resistant organisms (MDROs). We employed random-effect models to obtain pooled risk ratio (pRR) estimates. Heterogeneity was evaluated with I2 estimation and the Cochran Q statistic. Pooled risk ratios for C. difficile, MRSA, VRE, and MDRO were assessed separately. RESULTS In total, 20 studies were included in the final review: 13 studies using UVL systems and 7 studies using HPV systems. When the results of the UVL studies were pooled, statistically significant reduction ins C. difficile infection (CDI) (pRR, 0.64; 95% confidence interval [CI], 0.49-0.84) and VRE infection rates (pRR, 0.42; 95% CI, 0.28-0.65) were observed. No differences were found in rates of MRSA or gram-negative multidrug-resistant pathogens. CONCLUSIONS Ultraviolet light no-touch disinfection technology may be effective in preventing CDI and VRE infection. Infect Control Hosp Epidemiol 2018;39:20-31.

Abstract
Hospital infection control practices known as Contact Precautions are recommended for the management of people with pathogens such as methicillin-resistant Staphylococcus aureus or vancomycin-resistant Enterococci. Background: The patient is isolated, and staff are required to wear gloves, and a gown or apron when providing care. A notice is displayed to remind staff of these requirements and an 'alert' message is placed in the patient's medical record. Objective: The aim of this article is to discuss and explore whether practices used in hospitals to reduce the transmission of endemic antibiotic-resistant organisms are ethically justified in today's healthcare environment in the developed world. In order to do this, the history of the development of these practices is summarised, and the evidence base for their effectiveness is reviewed. Key bioethics principles are then discussed and contextualised from the perspective of hospital infection prevention and control, and an ethically superior model for the prevention and control of healthcare associated infection is proposed.

Abstract
Contact precautions are complex behavioral interventions. To better understand barriers to compliance, we conducted a prospective study that compared the time burden for health care workers caring for contact precautions patients versus other patients. We found that nurses spent significantly more time in the rooms of contact precautions patients. There was no significant change in physician timing. Future studies need to evaluate workflow changes so that barriers to contact precaution implementation can be fully understood and addressed.

Abstract
BACKGROUND The use of infection control measures in the management of vancomycin-resistant enterococci (VRE) is hotly debated. A risk-managed approach to VRE control after the introduction of 2 horizontal infection prevention measures-an environmental cleaning (EC) and an antimicrobial stewardship (AMS) program-was assessed. METHODS Routine screening for VRE was discontinued 6 and 4 months after introduction of the EC and AMS programs, respectively. Only 4 units (intensive care, burns-trauma, solid organ transplant, and bone marrow transplant units) where patients were deemed to be at increased risk for VRE infection continued screening and contact precautions. Cost avoidance and value-added benefits were monitored by the hospital finance department. VRE monitoring on these high-risk units and facility-wide comprehensive bacteremia surveillance continued as per established protocols. Surveillance for methicillin-resistant Staphylococcus aureus (MRSA) and Clostridium difficile infection (CDI) remained unchanged. RESULTS VRE bacteremia rates did not increase with the change to the VRE risk-managed approach. The number of patients requiring VRE isolation in all areas of the hospital decreased from an average of 32 to 6 beds per day. Statistically significant reductions in CDI and MRSA rates were observed possibly related to the aggressive decluttering, equipment cleaning, and AMS program elements. CONCLUSION A risk-managed approach to VRE can be implemented without adverse consequences and potentially with significant benefits to a facility.

Abstract
AIMS A discussion of conceptual frameworks applicable to the study of isolation precautions effectiveness according to Fawcett and DeSanto-Madeya's (2013) evaluation technique and their relative merits and drawbacks for this purpose. BACKGROUND Isolation precautions are recommended to control infectious diseases with high morbidity and mortality, but effectiveness is not established due to numerous methodological challenges. These challenges, such as identifying empirical indicators and refining operational definitions, could be alleviated though use of an appropriate conceptual framework. DESIGN Discussion paper. DATA SOURCES In mid-April 2014, the primary author searched five electronic, scientific literature databases for conceptual frameworks applicable to study isolation precautions, without limiting searches by publication date. IMPLICATIONS FOR NURSING By reviewing promising conceptual frameworks to support isolation precautions effectiveness research, this article exemplifies the process to choose an appropriate conceptual framework for empirical research. Hence, researchers may build on these analyses to improve study design of empirical research in multiple disciplines, which may lead to improved research and practice. CONCLUSION Three frameworks were reviewed: the epidemiologic triad of disease, Donabedian's healthcare quality framework and the Quality Health Outcomes model. Each has been used in nursing research to evaluate health outcomes and contains concepts relevant to nursing domains. Which framework can be most useful probably depends on whether the study question necessitates testing multiple interventions, concerns pathogen-specific characteristics and yields cross-sectional or longitudinal data. The Quality Health Outcomes model may be slightly preferred as it assumes reciprocal relationships, multi-level analysis and is sensitive to cultural inputs.

Abstract
BACKGROUND Meticillin-resistant Staphylococcus aureus (MRSA; also known as methicillin-resistant S aureus) is a common hospital-acquired pathogen that increases morbidity, mortality, and healthcare costs. Its control continues to be an unresolved issue in many hospitals worldwide. The evidence base for the effects of the use of gloves, gowns or masks as control measures for MRSA is unclear. OBJECTIVES To assess the effectiveness of wearing gloves, a gown or a mask when contact is anticipated with a hospitalised patient colonised or infected with MRSA, or with the patient's immediate environment. SEARCH METHODS We searched the Specialised Registers of three Cochrane Groups (Wounds Group on 5 June 2015; Effective Practice and Organisation of Care (EPOC) Group on 9 July 2013; and Infectious Diseases Group on 5 January 2009); CENTRAL (The Cochrane Library 2015, Issue 6); DARE, HTA, NHS EED, and the Methodology Register (The Cochrane Library 2015, Issue 6); MEDLINE and MEDLINE In-Process & Other Non-Indexed Citations (1946 to June week 1 2015); EMBASE (1974 to 4 June 2015); Web of Science (WOS) Core Collection (from inception to 7 June 2015); CINAHL (1982 to 5 June 2015); British Nursing Index (1985 to 6 July 2010); and ProQuest Dissertations & Theses Database (1639 to 11 June 2015). We also searched three trials registers (on 6 June 2015), references list of articles, and conference proceedings. We finally contacted relevant individuals for additional studies. SELECTION CRITERIA Studies assessing the effects on MRSA transmission of the use of gloves, gowns or masks by any person in the hospital setting when contact is anticipated with a hospitalised patient colonised or infected with MRSA, or with the patient's immediate environment. We did not assess adverse effects or economic issues associated with these interventions.We considered any comparator to be eligible. With regard to study design, only randomised controlled trials (clustered or not) and the following non-randomised experimental studies were eligible: quasi-randomised controlled trials (clustered or not), non-randomised controlled trials (clustered or not), controlled before-and-after studies, controlled cohort before-after studies, interrupted time series studies (controlled or not), and repeated measures studies. We did not exclude any study on the basis of language or date of publication. DATA COLLECTION AND ANALYSIS Two review authors independently decided on eligibility of the studies. Had any study having been included, two review authors would have extracted data (at least for outcome data) and assessed the risk of bias independently. We would have followed the standard methodological procedures suggested by Cochrane and the Cochrane EPOC Group for assessing risk of bias and analysing the data. MAIN RESULTS We identified no eligible studies for this review, either completed or ongoing. AUTHORS' CONCLUSIONS We found no studies assessing the effects of wearing gloves, gowns or masks for contact with MRSA hospitalised patients, or with their immediate environment, on the transmission of MRSA to patients, hospital staff, patients' caregivers or visitors. This absence of evidence should not be interpreted as evidence of no effect for these interventions. The effects of gloves, gowns and masks in these circumstances have yet to be determined by rigorous experimental studies, such as cluster-randomised trials involving multiple wards or hospitals, or interrupted time series studies.

Abstract
BACKGROUND Isolation-based practices in nursing homes (NHs) differ from those in acute care. NHs must promote quality of life while preventing infection transmission. Practices used in NHs to reconcile these goals of care have not been characterised. PURPOSE To explore decision-making in isolation-based infection prevention and control practices in NHs. METHODS A qualitative study was conducted with staff (eg, staff nurses, infection prevention directors and directors of nursing) employed in purposefully sampled US NHs. Semistructured, role-specific interview guides were developed and interviews were digitally recorded, transcribed verbatim and analysed using directed content analysis. The research team discussed emerging themes in weekly meetings to confirm consensus. RESULTS We inferred from 73 interviews in 10 NHs that there was variation between NHs in practices regarding who was isolated, when isolation-based practices took place, how they were implemented, and how they were tailored for each resident. Interviewees' decision-making depended on staff perceptions of acceptable transmission risk and resident quality of life. NH resources also influenced decision-making, including availability of private rooms, extent to which staff can devote time to isolation-based practices and communication tools. A lack of understanding of key infection prevention and control concepts was also revealed. CONCLUSIONS AND IMPLICATIONS Current clinical guidelines are not specific enough to ensure consistent practice that meets care goals and resource constraints in NHs. However, new epidemiological research regarding effectiveness of varying isolation practices in this setting is needed to inform clinical practice. Further, additional infection prevention and control education for NH staff may be required.

Abstract
Contact precautions are widely recommended to prevent multidrug-resistant organism (MDRO) transmission. However, conflicting data exist regarding their effectiveness. Prior systematic reviews examined contact precautions as part of a larger bundled approach, limiting ability to understand their effectiveness. The aim of this review was to characterize the effectiveness of contact precautions alone against transmission of any MDRO among adult acute care patients. Directed by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, comprehensive searches of four electronic scientific literature databases were conducted for studies published in English from January 2004 to June 2014. Studies were included if interventional, original research, evaluating contact isolation precautions against MDRO transmission among inpatients. Searches returned 284 studies, six of which were included in the review. These studies measured four different MDROs with one study showing a reduction in transmission. Whereas studies were of high quality regarding outcome operationalization and statistical analyses, overall quality was moderate to low due to poor intervention description, population characterization and potential biases. Where compliance was measured (N = 4), it presented a threat to validity because it included select parts of the intervention, ranged from 21% to 87%, and was significantly different across study phases (N = 2). The poor quality of evidence on this topic continues to limit interpretation of these data. Hence, this conflicting body of literature does not constitute evidence for or against contact precautions. We recommend that researchers consider power calculation, compliance monitoring, non-equivalent concurrent controls when designing future studies on this topic.

Abstract
BACKGROUND The emergence of multi-drug-resistant gram-negative rods (MDR-GNRs) has become a worldwide problem. To limit the emergence of MDR-GNRs, a tertiary care cancer center in Japan implemented a policy that requires the pre-emptive isolation of patients with organisms that have the potential to be MDR-GNRs. METHODS A retrospective analysis was performed. Any gram-negative bacillus isolates categorized as intermediate or resistant to at least 2 classes of antimicrobials were subjected to contact precautions. The incidence of patients with MDR-GNRs was analyzed. RESULTS There was no difference between the preintervention and intervention time periods in the detection rate of nonfermenting MDR-GNR species (0.15 per 10,000 vs 0.35 per 10,000 patient-days, P = .08). There was an increase in the detection rate of multi-drug-resistant Enterobacteriaceae (0.19 per 10,000 vs 0.56 per 10,000 patient-days, P = .007), which was prominent for extended-spectrum β-lactamase (ESBL)-producing organisms (0.19 per 10,000 vs 0.50 per 10,000 patient-days, P = .02). CONCLUSIONS Our intervention kept the emergence of multi-drug-resistant non-glucose-fermenting gram-negative bacilli to a small number, but it failed to prevent an increase in ESBL producers. Policies, such as active detection and isolation, are warranted to decrease the incidence of these bacilli.

Abstract
BACKGROUND Screening patients for methicillin-resistant Staphylococcus aureus (MRSA) colonization and contact precautions for colonized patients has been recommended when other control measures have been ineffective. METHODS We compared MRSA transmission rates following implementation of a bundle of control measures that included institutional culture change, surveillance for MRSA infection and transmission, and active screening for colonization in 2 similar Veterans Health Administration hospitals. One hospital employed contact precautions as defined by the Centers for Disease Control and Prevention, and the other hospital modified contact precautions, requiring only the use of gloves. RESULTS During the 4-year study period, there were 1.58 MRSA transmissions per 1,000 patient-days at hospital A and 1.56 MRSA transmissions per 1,000 patient-days at hospital B (P = .98). Both hospitals experienced significant reductions in MRSA health care-associated infections (HAI). There was no difference between hospital A and hospital B in incidence of MRSA HAIs or MRSA surgical site infections. Annual acquisition costs for cover gowns were $183,609 at hospital A and $25,812 at hospital B. CONCLUSION Significant reductions in MRSA HAI were associated with implementation of the MRSA control bundle. The bundle that included full contact precautions for colonized patients was no more effective in prevention of MRSA transmissions than a similar bundle that omitted the use of cover gowns.

Abstract
BACKGROUND Preventing health care-associated infections is essential to the safety and quality of health care. Although patients' experience of care under isolation is well established, little is known of health care workers' experiences when providing such care. This study explored the health professionals; lived experience of caring for patients under transmission-based precautions. METHODS Interpretive phenomenology was used to examine 12 health care professionals' lived experience of providing care under transmission-based precautions in 3 health care facilities in Australia. Data were obtained from in-depth interviews and observations of health professionals. FINDINGS The essential phenomena of "recognizing rapport" represented the health professionals' lived experience. Three themes emerged starting with (1) relationships with others, their rapport and communication with patients, patients' families and visitors, and colleagues. These relationships are influenced by (2) barriers to practice, such as personal level of comfort when wearing personal protective equipment, physical limitations of the environment, and management of workload and resources. Such barriers influence (3) patient outcomes, namely the quality of the care provided and adverse events. CONCLUSION In the context of caring for patients under transmission-based precautions, the relationships between health professionals and their patients are critical to the quality and safety of health care with respect to infection prevention and control.

Abstract
Staphylococcus aureus is a leading cause of both healthcare- and community-associated infections globally. S. aureus exhibits diverse clinical presentations, ranging from benign carriage and superficial skin and soft tissue infections to deep wound and organ/space infections, biofilm-related prosthesis infections, life-threatening bacteremia and sepsis. This broad clinical spectrum, together with the high incidence of these disease manifestations and magnitude of the diverse populations at risk, presents a high unmet medical need and a substantial burden to the healthcare system. With the increasing propensity of S. aureus to develop resistance to essentially all classes of antibiotics, alternative strategies, such as prophylactic vaccination to prevent S. aureus infections, are actively being pursued in healthcare settings. Within the last decade, the S. aureus vaccine field has witnessed two major vaccine failures in phase 3 clinical trials designed to prevent S. aureus infections in either patients undergoing cardiothoracic surgery or patients with end-stage renal disease undergoing hemodialysis. This review summarizes the potential underlying reasons why these two approaches may have failed, and proposes avenues that may provide successful vaccine approaches to prevent S. aureus disease in the future.

Abstract
Hospital-acquired infections (HAIs) are common in intensive care unit (ICU) patients and are associated with increased morbidity and mortality. There has been an increasing effort to prevent HAIs, and infection control practices are paramount in avoiding these complications. In the last several years, numerous developments have been seen in the infection prevention strategies in various health care settings. This article reviews the modern trends in infection control practices to prevent HAIs in ICUs with a focus on methods for monitoring hand hygiene, updates in isolation precautions, new methods for environmental cleaning, antimicrobial bathing, prevention of ventilator-associated pneumonia, central line-associated bloodstream infections, catheter-associated urinary tract infections, and Clostridium difficile infection.

Abstract
Isolation or cohorting of infected patients is an old concept. Its purpose is to prevent the transmission of microorganisms from infected or colonized patients to other patients, hospital visitors, and health care workers, who may subsequently transmit them to other patients or become infected or colonized themselves. Because the process of isolating patients is expensive, time-consuming, often uncomfortable for patients and may impede care, it should be implemented only when necessary. Conversely, failure to isolate a patient with multidrug-resistant microorganisms may lead to adverse outcomes, and may ultimately be expensive when one considers the direct costs of an outbreak investigation and the indirect costs of lost productivity. In this review, we argue that contact precautions are essential to control the spread of epidemic and endemic multidrug-resistant microorganisms, and discuss limitations of some available data.

Abstract
BACKGROUND The emergence and spread of multidrug-resistant organisms (MDROs) are causing a global crisis. Combating antimicrobial resistance requires prevention of transmission of resistant organisms and improved use of antimicrobials. OBJECTIVES To develop a Web-based information system for automatic integration, analysis, and interpretation of the antimicrobial susceptibility of all clinical isolates that incorporates rule-based classification and cluster analysis of MDROs and implements control chart analysis to facilitate outbreak detection. METHODS Electronic microbiological data from a 2200-bed teaching hospital in Taiwan were classified according to predefined criteria of MDROs. The numbers of organisms, patients, and incident patients in each MDRO pattern were presented graphically to describe spatial and time information in a Web-based user interface. Hierarchical clustering with 7 upper control limits (UCL) was used to detect suspicious outbreaks. The system's performance in outbreak detection was evaluated based on vancomycin-resistant enterococcal outbreaks determined by a hospital-wide prospective active surveillance database compiled by infection control personnel. RESULTS The optimal UCL for MDRO outbreak detection was the upper 90% confidence interval (CI) using germ criterion with clustering (area under ROC curve (AUC) 0.93, 95% CI 0.91 to 0.95), upper 85% CI using patient criterion (AUC 0.87, 95% CI 0.80 to 0.93), and one standard deviation using incident patient criterion (AUC 0.84, 95% CI 0.75 to 0.92). The performance indicators of each UCL were statistically significantly higher with clustering than those without clustering in germ criterion (P < .001), patient criterion (P = .04), and incident patient criterion (P < .001). CONCLUSION This system automatically identifies MDROs and accurately detects suspicious outbreaks of MDROs based on the antimicrobial susceptibility of all clinical isolates.

Abstract
BACKGROUND The study objective is to describe infection control policies aimed at multidrug-resistant organisms (MDRO) in California hospitals and assess the relationship among these policies, structural characteristics, and rates of methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus (VRE) bloodstream infections and Clostridium difficile infections. METHODS Data on infection control policies, structural characteristics, and MDRO rates were collected through a 2010 survey of California infection control departments. Bivariate and multivariable Poisson and negative binomial regressions were conducted. RESULTS One hundred eighty hospitals provided data (response rate, 54%). Targeted MRSA screening upon admission was reported by the majority of hospitals (87%). The majority of hospitals implemented contact precautions for confirmed MDRO and C difficile patients; presumptive isolation/contact precautions for patients with pending screens were less frequently implemented. Few infection control policies were associated with lower MDRO rates. Hospitals with a certified infection control director had significantly lower rates of MRSA bloodstream infections (P < .05). CONCLUSION Although most California hospitals are involved in activities to decrease MDRO, there is variation in specific activities utilized with the most focus placed on MRSA. This study highlights the importance of certification and its significant impact on infection rates. Additional research is needed to confirm these findings.

Abstract
You are responsible for a large medical surgical ICU. Your hospital administration has been very focused on reducing rates of hospital-acquired infections particularly in the wake of increasing public attention. However, it is time for budget preparation and your financial officer is concerned about the escalating costs associated with patient isolation and barrier precautions/personal protective equipment. Having become aware of the high costs associated with these interventions, you start to wonder about the wisdom of spending so much in this area. Your hospital administration wants your direction on next year's expenditures. You are debating whether the expense is worthwhile and advise your hospital administration accordingly.

Abstract
•Handwashing is the most important means of preventing nosocomial infection. Each pediatric intensive care unit should develop programs to increase compliance with hand hygiene. •Nonessential invasive devices should be removed. Establish routines that require individual patient evaluation of device use daily. •Antimicrobial stewardship aims to minimize overexposure and unnecessary use of broad-spectrum antibiotics. Antibiotic-resistant bacteria are an increasing concern as a cause of hospital-acquired infection, requiring a multipronged approach to control that includes adherence to isolation procedures, appropriate use of antibiotics, educational interventions, prescribing guidelines, and restriction of the use of some antibiotics. •A comprehensive infection prevention and control program allied with organizational quality and patient safety programs is an essential strategy for minimizing hospital-acquired infections. Critical care teams should establish strong collaborative partnerships with the infection prevention and control service. •Parents and visitors should be made partners of the infection control team to help prevent infection in their children.

Abstract
AIM This paper is a report of a study to determine if the terms used by nurses to describe isolation precautions are associated with correct identification of required personal protective equipment. BACKGROUND Isolation measures are important in the prevention of healthcare-associated infections. The terms used to describe categories of isolation have changed in response to new pathogens and with advances in infection prevention. METHODS For 3 months in 2009, nurses from an academic medical center on the East Coast of the United States of America completed a survey consisting of ten clinical scenarios which asked about recommended personal protective equipment and for the name of the recommended isolation type. Correct identification of required personal protective equipment was compared to use of an approved isolation category term, controlling for infection knowledge and demographic variables. RESULTS Three hundred and seventeen nurses gave responses to 2215 clinical scenarios. Use of non-approved category terms was associated with statistically significantly lower rates of correct personal protective equipment identification compared to use of an approved term (62.2% vs. 77.8%; P < 0.001). Specific PPE was also selected for use when not indicated - including gowns (42%), N-95 respirators (13%), fluid shield masks (13%) and sterile gloves (6%). CONCLUSION Inconsistent terminology for isolation precautions may contribute to variations in practice. Adoption of internationally accepted and standardized category terms may improve adherence to these precautions.

Abstract
OBJECTIVE To test whether a critical care consult team can be used to identify patients who have methicillin-resistant Staphylococcus aureus nasal colonization during a window period at which they are at highest risk for methicillin-resistant S. aureus infection and can most benefit from topical decolonization strategies. DESIGN Prospective cohort study. SETTING Two adult tertiary care hospitals. PATIENTS Patients with at least one risk factor for methicillin-resistant S. aureus nasal colonization who were seen by a critical care consult team for potential intensive care unit admission were enrolled. INTERVENTIONS Nasal cultures for methicillin-resistant S. aureus were performed on all subjects. All subjects were followed for the development of a methicillin-resistant S. aureus infection for 60 days or until hospital discharge. Demographic and outcome data were recorded on all subjects. MEASUREMENTS AND MAIN RESULTS Two hundred subjects were enrolled. Overall 29 of 200 (14.5%) were found to have methicillin-resistant S. aureus nasal colonization. Methicillin-resistant S. aureus infections occurred in seven of 29 (24.1%) subjects with methicillin-resistant S. aureus nasal colonization vs. one of 171 (0.6%) subjects without methicillin-resistant S. aureus nasal colonization (p < .001). Methicillin-resistant S. aureus clinical specimens were recovered in 15 of 29 (51.7%) subjects with methicillin-resistant S. aureus nasal colonization vs. two of 171 (1.2%) without methicillin-resistant S. aureus nasal colonization. CONCLUSIONS A critical care consult team can be used to rapidly recognize patients with methicillin-resistant S. aureus nasal colonization who are at very elevated risk for methicillin-resistant S. aureus infection. The use of such a team to recognize patients who have greatest potential benefit from decolonization techniques might reduce the burden of severe methicillin-resistant S. aureus infections.

Abstract
Annually, approximately 2 million patients suffer with healthcare-associated infections (HAIs) in the USA, and nearly 90,000 are estimated to die. The overall direct cost of HAIs to hospitals ranges from US$28 billion to 45 billion. While the range is wide, HAIs are clearly expensive. In addition, most HAIs are thought to be preventable; however, published guidelines are not congruent. Important policy changes include mandating hospitals to publically report HAI rates and a federal pay-for-performance measure that will no longer allow Medicare to pay more for patients with HAIs. Further rigorous economic evaluations of specific interventions, as well as on evaluations of the policies, are required.

Abstract
In Germany, recommendations on dealing with patients who are colonised with methicillin-resistant S. aureus (MRSA) for the inpatient sector have been published in 1999 by the Commission for Hospital Hygiene and Infection Prevention (KRINKO). Some challenges arise with regard to the practical implementation of the KRINKO recommendations. These challenges do not principally question the benefit of the recommendations but have come into criticism from users. In this commentary the German Society for Hospital Hygiene (DGKH) discusses some controversial issues and adds suggestions for unresolved problems regarding the infection control management of MRSA in healthcare settings.

Abstract
BACKGROUND Contact Precautions (CP) are a standard method for preventing patient-to-patient transmission of multiple drug-resistant organisms (MDROs) in hospital settings. With the ongoing worldwide concern for MDROs including methicillin-resistant Staphylococcus aureus (MRSA) and broadened use of active surveillance programs, an increasing number of patients are being placed on CP. Whereas few would argue that CP are an important tool in infection control, many reports and small studies have observed worse noninfectious outcomes in patients on CP. However, no review of this literature exists. METHODS We systematically reviewed the literature describing adverse outcomes associated with CP. We identified 15 studies published between 1989 and 2008 relating to adverse outcomes from CP. Nine were higher quality based on standardized collection of data and/or inclusion of control groups. RESULTS Four main adverse outcomes related to CP were identified in this review. These included less patient-health care worker contact, changes in systems of care that produce delays and more noninfectious adverse events, increased symptoms of depression and anxiety, and decreased patient satisfaction with care. CONCLUSION Although CP are recommended by the Centers for Disease Control and Prevention as an intervention to control spread of MDROs, our review of the literature demonstrates that this approach has unintended consequences that are potentially deleterious to the patient. Measures to ameliorate these deleterious consequences of CP are urgently needed.

Abstract
OBJECTIVE To assess the impact of isolation precautions on the incidence of patients colonized or infected with Acinetobacter baumannii (case patients) in a university hospital during the period from 1999 to 2006. DESIGN Ecological study. SETTING The Besançon University Hospital in France, a 1,200-bed acute care hospital with approximately 50,000 admissions per year. METHODS Using Poisson regression analysis, we evaluated a total of 350,000 patient-days to determine the annual incidence of case patients. This annual incidence was used as the outcome variable, and infection control practices, antibiotic use, and other aggregated data regarding patients' age, sex, McCabe score, and immune status were used as covariates. RESULTS The implementation of isolation precautions was independently and negatively associated with the incidence of patients colonized or infected with A. baumannii (relative risk, 0.50 [95% confidence interval, 0.40-0.64]; P<.001). CONCLUSIONS Our study suggests that the implementation of isolation precautions, in addition to standard precautions, effectively prevents the spread of A. baumannii in a hospital setting.

Abstract
Attempts to address the growing problem of healthcare-associated infections (HAIs) and their impact on healthcare systems have historically relied on infection control policies that recommend good hygiene through standard and enhanced precautions (e.g. barrier precautions and patient isolation). In order for infection control strategies to be effective, however, healthcare workers' behaviour must be congruent with these policies. The purposes of this systematic review were to evaluate studies testing the effectiveness of interventions aimed at changing healthcare workers' behaviour (in reducing HAIs) and to summarize the findings of the studies with the highest quality scores. A total of 33 published studies met the inclusion criteria and were evaluated. Four of these earned a study quality score of > or =80%. In all four significant reductions in HAI or colonization rates were reported. Behavioural interventions used in these high quality studies included an educational programme (in four), the formation of a multi-disciplinary quality improvement team (three), compliance monitoring and feedback (two), and a mandate to sign a hand hygiene requirement statement (one). In all 33 studies, bundles of two to five interventions were employed, making it difficult to determine the effectiveness of individual interventions. The usefulness of "care bundling" has recently been recognized and recommended by the Institute for Healthcare Improvement. Considering the multi-factorial nature of the HAI problem and the logistical and ethical difficulties of applying the randomized clinical trial approach to infection control research, it may be necessary to study interventions as sets of practices.
