Vancomycin-resistant Enterococcus faecium: impact of ending screening and isolation in a Danish University hospital. J Hosp Infect 2024; 146:82-92. [PMID: 38360093 DOI: 10.1016/j.jhin.2024.01.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 01/11/2024] [Accepted: 01/27/2024] [Indexed: 02/17/2024]
Abstract
BACKGROUND Substantial resources are used in hospitals worldwide to counteract the ever-increasing incidence of vancomycin-resistant and vancomycin-variable Enterococcus faecium (VREfm and VVEfm), but it is important to balance patient safety, infection prevention, and hospital costs. AIM To investigate the impact of ending VREfm/VVEfm screening and isolation at Odense University Hospital (OUH), Denmark, on patient and clinical characteristics, risk of bacteraemia, and mortality of VREfm/VVEfm disease at OUH. The burden of VREfm/VVEfm bacteraemia at OUH and the three collaborative hospitals in the Region of Southern Denmark (RSD) was also investigated. METHODS A retrospective cohort study was conducted including first-time VREfm/VVEfm clinical isolates (index isolates) detected at OUH and collaborative hospitals in the period 2015-2022. The intervention period with screening and isolation was from 2015 to 2021, and the post-intervention period was 2022. Information about clinical isolates was retrieved from microbiological databases. Patient data were obtained from hospital records. FINDINGS At OUH, 436 patients were included in the study, with 285 in the intervention period and 151 in the post-intervention period. Ending screening and isolation was followed by an increased number of index isolates. Besides a change in van genes, only minor non-significant changes were detected in all the other investigated parameters. Mortality within 30 days did not reflect the VREfm/VVEfm-attributable deaths, and in only four cases was VREfm/VVEfm infection the likely cause of death. CONCLUSION Despite an increasing number of index isolates, nothing in the short follow-up period supported a reintroduction of screening and isolation.

Abstract
Are Contact Precautions for Patients with MRSA Useful?MRSA infections lead to substantial morbidity and mortality. Hospitals commonly implement "contact precautions" to reduce MRSA transmission; however, recent studies have challenged the effectiveness of this strategy, and the use of contact precautions has been associated with certain adverse events. This article reviews the existing evidence and proposes a randomized trial to assess the efficacy of contact precautions in preventing MRSA transmission.

Abstract
BACKGROUND Colonisation by multidrug-resistant (MDR) bacteria is a global health issue. The identification of patients with a higher risk of colonisation is essential. Patients admitted to internal medicine services might represent a vulnerable population with a high risk of colonisation. This study was the first to assess social and clinical variables associated with a higher risk of perianal colonisation by MDR bacteria in a Spanish cohort of patients admitted to internal medicine service. METHODS Patients admitted to an internal medicine service during 12 months of recruitment (1 March 2022 to 1 March 2023) were included in the study. Perianal swabs were performed at admission to identify the presence of MDR bacteria. Social and clinical variables were collected following a directed acyclic graph. A cluster analysis was performed to identify clinical profiles of higher risk. Bivariate analyses and multivariable logistic regression models were fitted to identify potential predictors of MDR bacteria colonisation. RESULTS A total of 245 patients, according to the required sample size, were included. Of them, 46 (18.8%) were colonised by MDR bacteria in perianal swabs. Female sex, age > 80 years, dependency on activities of daily living, cognitive deterioration and living in long-term care facilities constituted the highest risk clinical profile. After adjustments, living in long-term care facilities and malnutrition remained the main risk factors identified. CONCLUSION Patients admitted to internal medicine services presented a high frequency of perianal colonisation by MDR bacteria. Social and clinical variables associated with bio-psycho-social susceptibility were associated with colonisation. Special surveillance is needed in internal medicine services to control the transmission.

JOURNAL OF MICROBIOLOGY, IMMUNOLOGY, AND INFECTION = WEI MIAN YU GAN RAN ZA ZHI 2023; 56:1054-1063. [PMID: 37380552 DOI: 10.1016/j.jmii.2023.06.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 05/19/2023] [Accepted: 06/10/2023] [Indexed: 06/30/2023]
Abstract
BACKGROUND Recent studies disputed the effectiveness of efforts to comply with contact precautions and isolation (CPI) considering relatively low intra-hospital transmission rate of healthcare facility-associated Clostridioides difficile infection (HCFA-CDI). We evaluated the potential causal effect of CPI on HCFA-CDI occurrence by comparing the incidence rate (IR) for different time periods with and without CPI implementation. METHODS Long-term observational time-series data were separated into three periods (pre-CPI: January 2012-March 2016, CPI: April 2016-April 2021, post-CPI: May 2021-December 2022). CPI was suspended owing to the restriction of isolation rooms during the COVID-19 pandemic. We inferred potential causal outcomes by comparing predicted and observed IRs of HCFA-CDI using interrupted time-series analyses, including the Bayesian structural time-series or autoregressive integrated moving average (ARIMA) model in the R-language or SAS software. RESULTS The monthly observed IR (44.9/100,000 inpatient-days) during the CPI period was significantly lower than the predicted IR (90.8) (-50.6% relative effect, P = 0.001). However, the observed IR (52.3) during the post-CPI period was significantly higher than the predicted IR (39.1) (33.6%, P = 0.001). The HCFA-CDI IR decreased during CPI (-14.3, P < 0.001) and increased post-CPI (5.4, P < 0.001) in the multivariable ARIMA model, which controlled for antibiotic usage, handwashing with soap and water, and number of toxin tests. CONCLUSIONS Various time-series models revealed that CPI implementation had a potential causal effect on the reduction of HCFA-CDI incidence.

Increasing trend of healthcare-associated infections due to vancomycin-resistant Enterococcus faecium (VRE-fm) paralleling escalating community-acquired VRE-fm infections in a medical center implementing strict contact precautions: An epidemiologic and pathogenic genotype analysis and its implications. JOURNAL OF MICROBIOLOGY, IMMUNOLOGY, AND INFECTION = WEI MIAN YU GAN RAN ZA ZHI 2023; 56:1045-1053. [PMID: 37599123 DOI: 10.1016/j.jmii.2023.07.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 07/24/2023] [Accepted: 07/31/2023] [Indexed: 08/22/2023]
Abstract
OBJECTIVE To clarify whether there were clandestine intra-hospital spreads of vancomycin-resistant Enterococcus faecium (VRE-fm) isolates that led to specific strain of VRE lingering in the hospital and/or developing outbreaks that rendered a progressively increasing trend of healthcare-associated infections due to VRE-fm (VRE-fm-HAIs). SETTING Despite implementing strict contact precautions for hospitalized patients with VRE-fm-infection/colonization, number of VRE-fm-HAIs in a medical centre in southern Taiwan were escalating in 2009-2019, paralleling an increasing trend of community-acquired VRE-fm- infections. METHODS We analyzed epidemiologic data and genotypes of non-duplicate VRE-fm isolates each grown from a normally sterile site of 89 patients between December 2016 and October 2018; multilocus sequence typing (MLST) and pulse-field gel electrophoresis (PFGE) typing were performed. RESULTS Totally 13 sequence types (STs) were found, and the 3 leading STs were ST17 (44%), ST78 (37%), and ST18 (6%); 66 pulsotypes were generated by PFGE. Four VRE-fm isolates grouped as ST17/pulsotype S, 2 as ST17/pulsotype AS, 2 as ST17/pulsotype AU, and 3 as ST78/pulsotype V grew from clinical specimens sampled less than one week apart from patients staying at different wards/departments and/or on different floors of the hospital. CONCLUSIONS Despite possible small transitory clusters of intra-hospital VRE-fm spreads, there was no specific VRE-fm strain lingering in the hospital leading to increasing trend of VRE-fm-HAIs during the study period. Strict contact precautions were able to curb intra-hospital VRE-fm spreads, but unable to curb the increasing trend of VRE-fm-HAIs with the backdrop of progressively increasing VRE-fm-infections/colorizations in the community.

Abstract
Healthcare-associated infections (HAIs) are a major problem in hospital infection control. Although HAIs can be suppressed using contact precautions, such precautions are expensive, and we can only apply them to a small fraction of patients (i.e., a limited budget). In this work, we focus on two clinical problems arising from the limited budget: (a) choosing the best patients to be placed under precaution given a limited budget to minimize the spread (the isolation problem), and (b) choosing the best patients to release when limited budget requires some of the patients to be cleared from precaution (the clearance problem). A critical challenge in addressing them is that HAIs have multiple transmission pathways such that locations can also accumulate 'load' and spread the disease. One of the most common practices when placing patients under contact precautions is the regular clearance of pathogen loads. However, standard propagation models like independent cascade (IC)/susceptible-infectious-susceptible (SIS) cannot capture such mechanisms directly. Hence to account for this challenge, using non-linear system theory, we develop a novel spectral characterization of a recently proposed pathogen load based model, 2-MODE-SIS model, on people/location networks to capture spread dynamics of HAIs. We formulate the two clinical problems using this spectral characterization and develop effective and efficient algorithms for them. Our experiments show that our methods outperform several natural structural and clinical approaches on real-world hospital testbeds and pick meaningful solutions.

Abstract
BACKGROUND Previous studies on adult patients in hospital isolation show that it can be highly stressful, with some patients affected by depression and anxiety. This study aimed to explore how children, adolescents, and their parents perceive isolation and how it affects them physically, psychologically, and socially. METHODS A qualitative approach was used comprising semi-structured interviews, participant observations, and field notes. FINDINGS Two adolescents and 13 parents were selected to participate in the interviews, while three children and their parents participated in participant observation. Besides the participant observation one of the adolescents and one parent also participated in interviews. The children and adolescents were isolated at the hospital due to bacterial or viral infections or were carriers of an antibiotic resistant bacteria. After performing a thematic analysis to identify patterns in the data, four themes emerged: 1. Differing information provided about bacteria, virus, hygiene precautions, and isolation, 2. Dependence on healthcare professionals, 3. Impact of the environment, and 4. Coping and psychological reactions on isolation. DISCUSSION The participants conveyed positive and negative experiences and emotions during isolation in relation to daily activities, psychological well-being, and social life. Adolescents and their parents requested clear comprehensible and consistent information on isolation from healthcare professionals. APPLICATION TO PRACTICE To improve hospital isolation for children, adolescents, and their parents, well-written information on isolation and hygiene precautions is crucial, as are evolving strategies to minimise social exclusion and the emotional impact of isolation.

Abstract
BACKGROUND Isolating patients infected or colonized with vancomycin-resistant enterococci (VRE) in a private room or cohort room to prevent hospital transmission is controversial. AIM To evaluate the effect of a relaxed isolation policy for VRE-infected or colonized patients on healthcare-associated (HA) VRE bacteraemia in an acute care hospital with a predominantly shared-room setting. METHODS The incidence of HA VRE bacteraemia was compared during a private isolation era (October 2014-September 2017), a cohort isolation era (October 2017-June 2020), and a no isolation era (July 2020-June 2022). Using Poisson regression modelling, an interrupted time-series analysis was conducted to analyse level changes and trends in incidences of HA VRE bacteraemia for each era. FINDINGS The proportion of VRE-infected or -colonized patients staying in shared rooms increased from 18.3% in the private isolation era to 82.6% in the no isolation era (P < 0.001). There was no significant difference in the incidences of HA VRE bacteraemia between the private isolation era and the cohort isolation era (relative risk: 1.01; 95% confidence interval: 0.52-1.98; P = 0.977) or between the cohort isolation era and the no isolation era (0.99; 0.77-1.26; P = 0.903). In addition, there was no significant slope increase in the incidence of HA VRE bacteraemia between any of the eras. CONCLUSION In a hospital with predominantly shared rooms, the relaxation of isolation policy did not result in increased HA VRE bacteraemia, when other infection control measures were maintained.

Effectiveness of patient and staff cohorting to reduce the risk of vancomycin-resistant enterococcus (VRE) acquisition: a retrospective cohort study during a VRE outbreak in Japan. J Hosp Infect 2023; 134:35-42. [PMID: 36669647 DOI: 10.1016/j.jhin.2022.11.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2022] [Revised: 11/18/2022] [Accepted: 11/26/2022] [Indexed: 01/19/2023]
Abstract
BACKGROUND Patient and staff cohorting is part of a bundle approach in the response to multi-drug-resistant organisms, but its effectiveness is not fully clarified. This study compared the risks of acquiring vancomycin-resistant Enterococcus faecium (VREfm) at a hospital during a VREfm outbreak based on contact characteristics in order to better understand the effectiveness of cohorting. METHODS Exposure came from contact with patients with VREfm (infectors), including existing patients with VREfm and patients who acquired VREfm during the study period. Contact was defined as length of contact time, degree of sharing space, and care by the same nurses as those caring for infectors between January and March 2018. The outcome was VREfm acquisition as determined through monthly stool or rectal screening cultures. Incidence rates were calculated based on contact patterns, and incidence rate ratios (IRRs) were compared. FINDINGS Among 272 inpatients (4038 patient-days), 43 patients acquired VREfm with the same or similar pulsotype. Incidence rates were 8.45 per 1000 patient-days when susceptible inpatients were on the same ward as an infector but cared for by different nurses (reference), 16.96 when susceptible inpatients were on the same ward as an infector and cared for by the same nurses [IRR 2.01, 95% confidence interval (CI) 0.62-10.28], and 52.91 when susceptible inpatients shared a room with an infector (IRR 6.26, 95% CI 1.61-35.40). CONCLUSION Compared with susceptible inpatients in a different room from infectors and not being cared for by the same nurses, the risk of VREfm acquisition could be six times higher for susceptible inpatients who are in the same room as infectors, and could be double for susceptible inpatients cared for by the same nurses as infectors.

Abstract
Fifty years of evolution in infection prevention and control programs have involved significant accomplishments related to clinical practices, methodologies, and technology. However, regulatory mandates, and resource and research limitations, coupled with emerging infection threats such as the COVID-19 pandemic, present considerable challenges for infection preventionists. This article provides guidance and recommendations in 14 key areas. These interventions should be considered for implementation by United States health care facilities in the near future.

Abstract
OBJECTIVE To define conditions in which contact precautions can be safely discontinued for methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE). DESIGN Interrupted time series. SETTING 15 acute-care hospitals. PARTICIPANTS Inpatients. INTERVENTION Contact precautions for endemic MRSA and VRE were discontinued in 12 intervention hospitals and continued at 3 nonintervention hospitals. Rates of MRSA and VRE healthcare-associated infections (HAIs) were collected for 12 months before and after. Trends in HAI rates were analyzed using Poisson regression. To predict conditions when contact precautions may be safely discontinued, selected baseline hospital characteristics and infection prevention practices were correlated with HAI rate changes, stratified by hospital. RESULTS Aggregated HAI rates from intervention hospitals before and after discontinuation of contact precautions were 0.14 and 0.15 MRSA HAI per 1,000 patient days (P = .74), 0.05 and 0.05 VRE HAI per 1,000 patient days (P = .96), and 0.04 and 0.04 MRSA laboratory-identified (LabID) events per 100 admissions (P = .57). No statistically significant rate changes occurred between intervention and non-intervention hospitals. All successful hospitals had low baseline MRSA and VRE HAI rates and high hand hygiene adherence. We observed no correlations between rate changes after discontinuation and the assessed hospital characteristics and infection prevention factors, but the rate improved with higher proportion of semiprivate rooms (P = .04). CONCLUSIONS Discontinuing contact precautions for MRSA/VRE did not result in increased HAI rates, suggesting that contact precautions can be safely removed from diverse hospitals, including community hospitals and those with lower proportions of private rooms. Good hand hygiene and low baseline HAI rates may be conditions permissive of safe removal of contact precautions.

Abstract
Objectives: The present study aims to determine Patient Safety in hospitalized patients with COVID-19 compared to non-COVID-19 ones and find predisposing factors of nursing errors according to nurses’ perceptions. Methods: This descriptive-comparative research employed data from 800 nurses in eight Iranian hospitals in 2021 using three researcher-made questionnaires of sociodemographic, patient safety indicators, and predisposing factors of nursing errors, with high reliability and validity. The collected data were analyzed using ANOVA, independent t-test, and the SPSS22 software. Results: The mean patient safety scores in patients with and without COVID-19 were 3.42 ± 0.17 and 3.74 ± 0.06, respectively. The highest differences in patient safety were attributed to infection control (0.66) and patient fall (0.56) dimensions. The most common causes of nursing errors were related to management (2.67 ± 1.39), and the most common predisposing factors of nursing errors were high workload, low ratio of nurses to patients, and fatigue. Conclusions: COVID-19 patients have lower safety than non-COVID ones. Also, improper management and high workload lead to nursing errors. Therefore, the authorities must devise appropriate strategies to reduce the nurses’ workload and improve patient safety, especially in COVID-19 patients.

Abstract
Background The optimal extent of screening of contact patients (CoPat) after exposure to patients infected or colonized with vancomycin-resistant enterococci (VRE) remains controversial. Methods We retrospectively developed a new risk stratification for screening patients exposed to VRE, based on data from three outbreaks—two with Enterococcus faecium vanB and one with Enterococcus faecium vanA involving 1096 CoPat—in a low endemic setting. We classified them into four risk groups: three on environmental exposure, one by healthcare exposure: high (sharing the same room/bathroom with a VRE-colonized patient), medium (hospitalization in the same room after a VRE-colonized patient’s discharge until terminal disinfection including ultraviolet C (UVc)-disinfection), low (hospitalized in the same room within three weeks before the VRE-colonized patient), and “staff” (screening of patients having the same medical care team). Results VRE-transmission occurred in 7.9% in the high-risk group compared to 0.6% and 0% in the medium and low risk groups. There was a significant trend to higher rates of transmission by risk level of exposure (p < 0.001). In the “staff” group, VRE transmission rate was 2.3%. Conclusion Based on this stratification, we recommend to focus screening of exposed CoPat on the high-risk and “staff” group, saving resources and costs, but larger studies will allow to further improve the yield of VRE screening in the outbreak setting.

Abstract
IMPORTANCE Although contact isolation has been widely recommended for multidrug-resistant organisms, contact isolation has raised some concerns that it may bring unintended patient harms. OBJECTIVE To compare adverse events between a contact isolation group with vancomycin-resistant Enterococcus (VRE) and a matched comparison group using a relatively large data set from full electronic medical records (EMR) and propensity score-matching methods. DESIGN, SETTING, AND PARTICIPANTS This retrospective, matched cohort study was conducted at Seoul National University Bundang Hospital (SNUBH) in Korea, a tertiary, university-affiliated hospital that has 1337 inpatient beds. Participants included a total of 98 529 hospitalized adult patients (aged ≥18 years) during 2015 to 2017. EXPOSURES Contact isolation in a single or shared double room. MAIN OUTCOMES AND MEASURES As adverse contact isolation-related outcomes, falls and pressure ulcers were included. All relevant EMR data were extracted from the SNUBH clinical data warehouse. Risk factors for adverse events were included in the propensity score model based on literature reviews, such as Braden scale score and Hendrich II fall risk score. A fine stratification and weighting (FSW) and a 1:10 nearest neighbor (NN) propensity score matching as a sensitivity analysis were adopted to compare adverse events between the 2 groups for the observation period from the study entry date and the exit date. Time-to-event analyses with a Cox proportional hazard model were conducted in December 2021. RESULTS For comparison of outcomes in wards, 177 patients (mean [SD] age, 67.38 [14.12] years; 98 [55.4%] female) with VRE and 93 022 patients (mean [SD] age, 56.44 [16.88] years; 49 462 [53.2%] female) without VRE were included and no difference was found in basic characteristics from the FSW (VRE contact isolation [n = 172] vs comparison [n = 69 434]) as well as from the 1:10 NN (VRE contact isolation [n = 168] vs comparison [n = 1650]). Among 177 patients with VRE contact isolation, 8 pressure ulcers and 3 falls occurred during their hospital stays; incidence rates of adverse events were 2.5 and 0.9 per 1000 patient-days, respectively (pressure ulcer incidence rate from the FSW: 2.53 per 1000 patient-days [95% CI, 1.09-4.99 per 1000 patient-days]; pressure ulcer incidence rate from the 1:10 NN: 2.54 per 1000 patient-days [95% CI, 1.10-5.01 per 1000 patient-days]; fall incidence rate from the FSW: 0.87 per 1000 patient-days [95% CI, 0.18-2.54 per 1000 patient-days]; fall incidence rate from the 1:10 NN: 0.87 per 1000 patient-days [95% CI, 0.18-2.55 per 1000 patient-days]). The hazard ratios for adverse events showed no statistically significant differences for both groups: 1.42 (95% CI, 0.67-2.99) for pressure ulcer and 0.66 (95% CI, 0.20-2.13) for fall from the FSW. CONCLUSIONS AND RELEVANCE In this cohort study, no association was found between the likelihood of adverse events and contact isolation using propensity score-matching methods and closely related covariates for adverse events.

Abstract
Patients with vancomycin-resistant Enterococcus (VRE) colonization should be managed in an isolation room with contact precautions. We herein report a patient whose colorectal carriage of VRE was successfully decolonized using concomitant bowel irrigation with polyethylene glycol, probiotics, and oral antimicrobials, linezolid and orally-administered daptomycin, for release from isolation and contact precautions. We therefore would like to suggest a potential strategy for managing patients with VRE colonization.

Abstract
Background: Patient safety is a major concern for health care professionals. Medication errors have been considered a major indicator of health care quality. The lack of pharmacological knowledge is a cause of medication error among nurses. Objectives: The purpose of this study was to investigate the relationship between pharmacological knowledge and the probability of medical errors in nurses working in Urmia hospitals in 2020. Methods: This cross-sectional study included 490 nurses randomly selected from among those working in hospitals of Urmia in 2020. The data collection tool was a multiple-choice questionnaire about knowledge and pharmacological skills consisting of 3 sections: demographic information, nurses’ drug knowledge, and the confidence level of response in nurses. To analyze questions and hypotheses via SPSS version 21, the t-test and analysis of variance (ANOVA) were employed. Results: The highest pharmaceutical knowledge scores of nurses were related to methods of administration (2.9 ± 1.01 [72.56%]), and the lowest score was related to drug management (1.05 ± 0.63 [52.84%]). The mean of error probability was very low in 28.81% of nurses, low in 37.66%, high in 11.34%, and very high in 22.85%. Pharmaceutical knowledge had a significant relationship with gender, wards, type of hospital, and number of children (P < 0.05 for all). Conclusions: Since the nurses’ level of pharmaceutical knowledge has an important role in the correct prescription of medicine, we suggest that nurse managers and educational supervisors in the field of nursing use in-service training programs and prepare training booklets and posters to promote nurses’ pharmaceutical knowledge in this field.

Abstract
Vancomycin-resistant enterococcus (VRE) is a pathogen of growing concern due to increasing development of antibiotic resistance, increasing length of hospitalizations and excess mortality. The utility of some infection control practices are debatable, as newer developments in infection prevention strategies continued to be discovered. This article summarizes the significance of VRE and VRE transmission, along with highlighting key changes in infection control practices within the past 5 years.

Abstract
BACKGROUND Patient isolation is widely recommended and used in healthcare institutions to prevent transmission of MDRO. However, its risk-benefit ratio is debated. AIM We undertook a systematic literature review and meta-analysis since 2009 to assess, based on the newly published studies, whether or not there are physical and psychological adverse events associated with patient isolation. METHODS Systematic literature review and meta-analysis were performed in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Studies were systematically searched from PubMed, from the 1st of may 2009 till the 31st of January 2020. The concepts of the research questions were defined as: "Adverse events", "patient isolation or cohorting", and "multi-drug resistant organisms colonized or infection patients". Three reviewers independently screened studies and extracted data. All statistical analysis was performed with Stata Software and R. FINDINGS After screening titles of 15921 articles, abstracts of 196 and reviewing full texts of 50 studies, we included 19 studies. Studies were divided into 3 groups: 4 qualitative studies, 7 observational studies suitable for meta-analysis and 8 other observational studies. Meta-analysis shows no adverse events related to clinical care or patient's experience associated with patient isolation. CONCLUSIONS More studies with correct methodology, including a control group and standardized inclusion criteria, must be conducted to confirm our results.

Abstract
Previous research has shown that patients in infectious-agent isolation are at greater risk for certain types of safety-related events. We conducted a study to explore the relationship between the various types of events that occur in an isolation environment and the associated factors, which may have implications for the likelihood of the event and severity of patient harm. We conducted a query of the Pennsylvania Patient Safety Reporting System (PA-PSRS) database to identify event reports submitted by acute care hospitals between January 1 and September 30, 2020. We identified 484 relevant event reports from 94 hospitals for inclusion in our descriptive study (excluding near-miss events). We measured the frequency of relationship between categories of safety-related event types and 18 categories of associated factors. Among the seven categories of event types, the most frequently identified were skin integrity (141 of 484, 29%), falls (129 of 484, 27%), and medication-related (78 of 484, 16%). Across all 18 categories of associated factors, which had or may have had an influence on the event type, the most frequent were patient’s mental status (80 of 484, 17%), staff’s time to don personal protective equipment (62 of 484, 13%), and patient’s interference with equipment/supplies (45 of 484, 9%). Overall, our results revealed that the frequency of certain associated factors varied considerably from one event type to another, which indicates that the relation between event types and associated factors should guide selection of risk mitigation strategies. We encourage readers to leverage our results along with Table 9, which provides a list of challenges identified in an isolation environment and potential solutions. We envision hospital staff proactively and systematically using the information in our manuscript to facilitate their evaluation of the isolation environment and prioritization of risk mitigation strategies.

Abstract
BACKGROUND In 2009, the Israeli Ministry of Health implemented in post-acute care hospitals (PACHs) a process of discontinuing carbapenem-resistant Enterobacteriaceae (CRE) carrier status. We evaluated the policy's impact on isolation-days, CRE prevalence among known carriers who had completed clearance testing, and CRE acquisition among noncarriers. METHODS This retrospective study summarized findings from all 15 PACHs in 2009-2017. CRE carriers were considered cleared and removed from contact isolation after 2 rectal cultures negative for CRE and polymerase chain reaction negative for carbapenemases. Data sources included routine surveillance and 4 point prevalence surveys conducted from 2011 to 2017. RESULTS During the study period, 887 of 6101 CRE carriers (14.5%) completed clearance testing. From 2013 to 2016, the percentage of patient-days in CRE isolation decreased from 9.4% to 3.9% (P = .008). In all surveys combined, there were 819 known CRE carriers; 411 (50%) had completed clearance testing. Of these, 11.4% (47/411) were CRE positive in the survey. At the ward level, the median percentage of patients with no CRE history who were positive on survey decreased from 11.3% in 2011 to 0% in 2017 (P < .001). We found no ward-level correlation between the proportion of carriers who completed clearance and new acquisitions (ρ = 0.02, P = .86). CONCLUSIONS A process for discontinuing CRE carrier status in PACHs led to a significant reduction in the percentage of patient-days in contact isolation without increasing CRE acquisitions among noncarriers.

Abstract
BACKGROUND Contact precautions (CP) are a widely adopted strategy to prevent cross-transmission of organisms, commonly methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE). Some hospitals have discontinued CP for patients with MRSA or VRE; however, the impact on hospital-acquired infection rates (HAI) has not been assessed systematically. METHODS Retrospective multicenter interrupted time series between 2002 and 2017 at three academic hospitals. Participating hospitals discontinued CP for patients with contained body fluids who were colonized or infected with MRSA or VRE. The primary intervention was stopping the use of CP. Secondary interventions were horizontal infection prevention strategies. The primary outcomes were rates of central line-associated bloodstream infections, catheter-associated urinary tract infections, mediastinal surgical site infection, and ventilator-associated pneumonia due to MRSA, VRE, or any organism using Centers for Disease Control and Prevention National Healthcare Safety Network surveillance definitions. RESULTS Central line-associated bloodstream infections, catheter-associated urinary tract infections, mediastinal surgical site infection, and ventilator-associated pneumonia rates trended down at each institution. There were no statistically significant increases in these infections associated with discontinuing CP. Individual horizontal infection prevention strategies variably impacted HAI outcomes. CONCLUSIONS Stopping the routine use of CP for patients with contained body fluids who are colonized or infected with MRSA or VRE did not result in increased HAIs. Bundled horizontal infection prevention strategies resulted in sustained HAI reductions.

Abstract
OBJECTIVE To determine whether isolated patients admitted to hospital have a higher incidence of adverse events (AEs), to identify their nature, impact and preventability. DESIGN Prospective cohort study with isolated and non-isolated patients. SETTING One public university hospital in the Valencian Community (southeast Spain). PARTICIPANTS We consecutively collected 400 patients, 200 isolated and 200 non-isolated, age ≥18 years old, to match according to date of entry, admission department, sex, age (±5 years) and disease severity from April 2017 to October 2018. EXCLUSION CRITERIA patients age <18 years old and/or reverse isolation patients. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome as the AE, defined according to the National Study of Adverse Effects linked to Hospitalisation (Estudio Nacional Sobre los Efectos Adversos) criteria. Cumulative incidence rates and AE incidence density rates were calculated. RESULTS The incidence of isolated patients with AEs 16.5% (95% CI 11.4% to 21.6%) compared with 9.5% (95% CI 5.4% to 13.6%) in non-isolated (p<0.03). The incidence density of patients with AEs among isolated patients was 11.8 per 1000 days/patient (95% CI 7.8 to 15.9) compared with 4.3 per 1000 days/patient (95% CI 2.4 to 6.3) among non-isolated patients (p<0.001). The incidence of AEs among isolated patients was 18.5% compared with 11% for non-isolated patients (p<0.09). Among the 37 AEs detected in 33 isolated patients, and the 22 AEs detected in 19 non-isolated patients, most corresponded to healthcare-associated infections (HAIs) for both isolated and non-isolated patients (48.6% vs 45.4%). There were significant differences with respect to the preventability of AEs, (67.6% among isolated patients compared with 52.6% among non-isolated patients). CONCLUSIONS AEs were significantly higher in isolated patients compared with non-isolated patients, more than half being preventable and with HAIs as the primary cause. It is essential to improve training and the safety culture of healthcare professionals relating to the care provided to this type of patient.

Impact of a Clostridioides Difficile Testing Computerized Clinical Decision Support Tool on an Adult Stem Cell Transplantation and Hematologic Malignancies Unit. Transplant Cell Ther 2020; 27:94.e1-94.e5. [PMID: 33045386 DOI: 10.1016/j.bbmt.2020.10.005] [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: 09/09/2020] [Revised: 10/03/2020] [Accepted: 10/04/2020] [Indexed: 12/19/2022]
Abstract
Clostridioides difficile infection rates are higher in hospitalized hematopoietic stem cell transplantation (HSCT) recipients and patients with hematologic malignancy (HM) compared with the general population. This is related both to extensive exposure to antibiotics as well as to frequent and often prolonged hospitalization. In this population, with numerous potential causes of diarrhea, a subset of C difficile detected is presumed to represent colonization rather than clinical infection. The use of decision support tools to guide ordering in hospitalized patients has been reported to decrease both C difficile testing and detection rates. Following implementation of a computerized decision support tool on our HSCT/HM unit, we observed a >2-fold decrease in C difficile testing volume and National Healthcare Safety Network-defined laboratory identifications of C difficile. Furthermore, the rate of oral vancomycin use, as well as the incidence of vancomycin-resistant enterococci colonization and bloodstream infection, decreased in the postintervention period.

Abstract
Purpose of review There is a continuing debate regarding contact precaution (CP) usage for endemic multidrug-resistant organisms (MDROs). In this review, we examine current recommendations for CP and highlight differences in CP use between endemic and non-endemic MDROs. Recent findings The discontinuation of CP had no effect on the incidence of methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococci. The evidence regarding CP for extended-spectrum beta-lactamase producing Enterobacteriaceae is inconclusive, highlighting the need for more research to determine best infection control strategies. Carbapenem-resistant Enterobacteriaceae maintains a sporadic pattern in the USA, supporting current recommendations to use CP for colonized and infected patients. MDR Acinetobacter baumannii (MDR-AB) is extremely virulent and responsible for outbreaks in healthcare settings, emphasizing the need for CP use with MDR-AB infected patients. Candida auris (C. auris) is often misdiagnosed; it is resistant to UV light and quaternary ammonium low-level disinfection. Because little is known about the transmission of C. auris, significant caution and CP use are necessitated. There is little research on vancomycin-resistant S. aureus (VRSA) control strategies due to its rarity; thus, CP is strongly recommended. Summary Contact precautions are frequently part of a bundled infection control approach that involves meticulous hand hygiene, patient decolonization, chlorhexidine gluconate bathing, and reducing the use of invasive devices. Healthcare facilities should continue to utilize CP for non-endemic MDROs and the presence of endemic MDROs; however, CP may not add benefit to the current infection prevention bundle approach.

Abstract
BACKGROUND Health care personnel (HCP) use of personal protective equipment (PPE) reduces infectious disease transmission. However, PPE compliance remains low. The objective of this study was to better understand how HCP perceptions factor into PPE decision making as well as how organizational processes and the environment impact behavior. METHODS This qualitative study used observation and focus groups at 2 medical centers. Data were analyzed using thematic analysis. RESULTS The decision to use PPE and to follow precaution practices was influenced by risk perception as well as organizational and environmental factors. Perceived risk, related to certain organisms and work tasks, was considered by HCP when deciding to use PPE. Organizational processes, such as policies that were not applied uniformly, and environmental factors, such as clean versus contaminated space, also played a role in HCP PPE use. DISCUSSION Because HCP seemed focused on organisms and work tasks, education on specific organisms and helping HCP think through their workflow may be more effective in conveying the importance of PPE in reducing transmission. Additionally, isolation practices should be compared across disciplines to ensure they complement, rather than contradict, one another. Assessment of the environment may help protect HCP and patients from infectious organisms. CONCLUSION Preventing the spread of infectious organisms should not depend solely on PPE use, but should also be recognized as an organizational responsibility.

Abstract
BACKGROUND The impact of discontinuing contact precautions (CPs) for patients with select multidrug-resistant organisms on bacteremia infection rates was evaluated in this quality improvement project. METHODS The removal of use of CPs, with increased focus on standard precautions, for all patients with methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus (VRE) colonization/infection was piloted via a quality improvement project over a 3-month period. RESULTS CP was discontinued in December 2018. Comparing 3 months pre- and postchange, the overall incidence density rate decreased for hospital-onset (HO) laboratory-identified (LabID) MRSA bacteremia (0.07 vs 0.02; P = .52), whereas HO LabID VRE bacteremia rates remained the same (0.00 vs 0.00). Overall estimated financial savings, including personal protective equipment ($15,375) and staff time ($17,165), was $32,540 for the project period, with annualized estimated savings of $130,160. CONCLUSIONS In this pilot study evaluating the discontinuance of CPs, there was no evidence of an increase in HO MRSA or VRE LabID bacteremia incidence density rates. This practice change may be safely implemented at similar health care facilities.

Abstract
BACKGROUND The relevance of vancomycin resistance in enterococcal blood stream infections (BSI) is still controversial. Aim of this study was to outline the effect of vancomycin resistance of Enterococcus faecium on the outcome of patients with BSI after orthotopic liver transplantation (OLT). METHODS The outcome of OLT recipients developing BSI with vancomycin-resistant (VRE) versus vancomycin-susceptible Enterococcus faecium (VSE) was compared based on data extraction from medical records. Multivariate regression analyses identified risk factors for mortality and unfavourable outcomes (defined as death or prolonged intensive care stay) after 30 and 90 days. RESULTS Mortality was similar between VRE- (n = 39) and VSE- (n = 138) group after 30 (p = 0.44) or 90 days (p = 0.39). Comparable results occurred regarding unfavourable outcomes. Mean SOFANon-GCS score during the 7-day-period before BSI onset was the independent predictor for mortality at both timepoints (HR 1.32; CI 1.14-1.53; and HR 1.18; CI 1.08-1.28). Timely appropriate antibiotic therapy, recent ICU stay and vancomycin resistance did not affect outcome after adjusting for confounders. CONCLUSION Vancomycin resistance did not influence outcome among patients with Enterococcus faecium bacteraemia after OLT. Only underlying severity of disease predicted poor outcome among this homogenous patient population.

Abstract
Vancomycin-resistant enterococci (VRE) are important nosocomial pathogens that require effective infection control measures, representing a challenge for healthcare systems. This study aimed at identifying risk factors associated with prolonged VRE carriage and determining the rate of clearance that allows the discontinuation of contact precautions. During a 2-year study, screening was performed in patients with a history of VRE or at risk of becoming colonized. After bacterial identification and antibiotic susceptibility testing, glycopeptide resistance was confirmed by PCR. Isolates were compared via whole genome sequence-based typing. Risk factors were recorded, and follow-up screening was performed upon readmission, defining patients as long-term carriers if still colonized ≥10 weeks after first detection. Of 1059 patients positive for VRE, carriage status was assessed upon readmission in 463 patients. VRE was cleared in 56.4% of the cases. Risk factors associated with long-term persistence were hospital stays (frequency, length), hemato-oncological disease, systemic treatment with steroids, and use of antibiotics. No specific genotypic clustering was observed in patients with VRE clearance or persistence. VRE clearance is possibly underestimated. The identification of risk factors favoring long-term carriage may contribute to a targeted implementation of infection control measures upon readmission of patients with history of VRE.

Abstract
BACKGROUND Use of single-bed rooms for control of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae is under debate; the added value when applying contact precautions has not been shown. We aimed to assess whether an isolation strategy of contact precautions in a multiple-bed room was non-inferior to a strategy of contact precautions in a single-bed room for preventing transmission of ESBL-producing Enterobacteriaceae. METHODS We did a cluster-randomised, crossover, non-inferiority study on medical and surgical wards of 16 Dutch hospitals. During two consecutive study periods, either contact precautions in a single-bed room or contact precautions in a multiple-bed room were applied as the preferred isolation strategy for patients with ESBL-producing Enterobacteriaceae cultured from a routine clinical sample (index patients). Eligible index patients were aged 18 years or older, had no strict indication for barrier precautions in a single-bed room, had a culture result reported within 7 days of culture and before discharge, and had no wardmate known to be colonised or infected with an ESBL-producing Enterobacteriaceae isolate of the same bacterial species with a similar antibiogram. Hospitals were randomly assigned in a 1:1 ratio by computer to one of two sequences of isolation strategies, stratified by university or non-university hospital. Allocation was masked for laboratory technicians who assessed the outcomes but not for patients, treating doctors, and infection-control practitioners enrolling index patients. The primary outcome was transmission of ESBL-producing Enterobacteriaceae to wardmates, which was defined as rectal carriage of an ESBL-producing Enterobacteriaceae isolate that was clonally related to the index patient's isolate in at least one wardmate. The primary analysis was done in the per-protocol population, which included patients who were adherent to the assigned room type. A 10% non-inferiority margin for the risk difference was used to assess non-inferiority. This study is registered with Nederlands Trialregister, NTR2799. FINDINGS 16 hospitals were randomised, eight to each sequence of isolation strategies. All hospitals randomised to the sequence single-bed room then multiple-bed room and five of eight hospitals randomised to the sequence multiple-bed room then single-bed room completed both study periods and were analysed. From April 24, 2011, to Feb 27, 2014, 1652 index patients and 12 875 wardmates were assessed for eligibility. Of those, 693 index patients and 9527 wardmates were enrolled and 463 index patients and 7093 wardmates were included in the per-protocol population. Transmission of ESBL-producing Enterobacteriaceae to at least one wardmate was identified for 11 (4%) of 275 index patients during the single-bed room strategy period and for 14 (7%) of 188 index patients during the multiple-bed room strategy period (crude risk difference 3·4%, 90% CI -0·3 to 7·1). INTERPRETATION For patients with ESBL-producing Enterobacteriaceae cultured from a routine clinical sample, an isolation strategy of contact precautions in a multiple-bed room was non-inferior to a strategy of contact precautions in a single-bed room for preventing transmission of ESBL-producing Enterobacteriaceae. Non-inferiority of the multiple-bed room strategy might change the current single-bed room preference for isolation of patients with ESBL-producing Enterobacteriaceae and, thus, broaden infection-control options for ESBL-producing Enterobacteriaceae in daily clinical practice.

The discontinuation of contact precautions for methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus: Impact upon patient adverse events and hospital operations. BMJ Qual Saf 2019; 29:1-2. [PMID: 31320496 DOI: 10.1136/bmjqs-2018-008926] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2018] [Revised: 06/11/2019] [Accepted: 06/29/2019] [Indexed: 01/08/2023]
Abstract
BACKGROUND Contact precautions for endemic methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) are a resource-intensive intervention to reduce healthcare-associated infections, potentially impeding patient throughput and limiting bed availability to isolate other contagious pathogens. We investigated the impact of the discontinuation of contact precautions (DcCP) for endemic MRSA and VRE on patient outcomes and operations metrics in an acute care setting. METHODS This is a retrospective, quasi-experimental analysis of the 12 months before and after DcCP for MRSA and VRE at an academic medical centre. The frequency for bed closures due to contact isolation was measured, and personal protective equipment (PPE) expenditures and patient satisfaction survey results were compared using the Wilcoxon signed-rank test. Using an interrupted time series design, emergency department (ED) admission wait times and rates of patient falls, pressure ulcers and nosocomial MRSA and VRE clinical isolates were compared using GEEs. RESULTS Prior to DcCP, bed closures for MRSA and/or VRE isolation were associated with estimated lost hospital charges of $9383 per 100 bed days (95% CI: 8447 to 10 318). No change in ED wait times or change in trend was observed following DcCP. There were significant reductions in monthly expenditures on gowns (-61.0%) and gloves (-16.3%). Patient satisfaction survey results remained stable. No significant changes in rates or trends were observed for patient falls or pressure ulcers. Incidence rates of nosocomial MRSA (1.58 (95% CI: 0.82 to 3.04)) and VRE (1.02 (95% CI: 0.82 to 1.27)) did not significantly change. CONCLUSIONS DcCP was associated with an increase in bed availability and revenue recovery, and a reduction in PPE expenditures. Benefits for other hospital operations metrics and patient outcomes were not identified.

Abstract
OBJECTIVE Clostridioides difficile (C. difficile) poses a major challenge to the healthcare system. We assessed factors that should be considered when designing subprocesses of a C. difficile infection (CDI) prevention bundle. DESIGN Phenomenological qualitative study. METHODS We conducted 3 focus groups of environmental services (EVS) staff, physicians, and nurses to assess their perspectives on a CDI prevention bundle. We used the Systems Engineering Initiative for Patient Safety (SEIPS) model to examine 5 subprocesses of the CDI bundle: diagnostic testing, empiric isolation, contact isolation, hand hygiene, and environmental disinfection. We coded transcripts to the 5 SEIPS elements and ensured scientific rigor. We sought to determine common, unique, and conflicting factors across stakeholder groups and subprocesses of the CDI bundle. RESULTS Each focus group lasted 1.5 hours on average. Common work-system barriers included inconsistencies in knowledge and practice of CDI management procedures; increased workload; poor setup of aspects of the physical environment (eg, inconvenient location of sinks); and inconsistencies in CDI documentation. Unique barriers and facilitators were related to specific activities performed by the stakeholder group. For instance, algorithmic approaches used by physicians facilitated timely diagnosis of CDI. Conflicting barriers or facilitators were related to opposing objectives; for example, clinicians needed rapid placement of a patient in a room while EVS staff needed time to disinfect the room. CONCLUSIONS A systems engineering approach can help to holistically identify factors that influence successful implementation of subprocesses of infection prevention bundles.

Abstract
BACKGROUND Targeted screening for carbapenem-resistant organisms (CROs), including carbapenem-resistant Enterobacteriaceae (CRE) and carbapenemase-producing organisms (CPOs), remains limited; recent data suggest that existing policies miss many carriers. OBJECTIVE Our objective was to measure the prevalence of CRO and CPO perirectal colonization at hospital unit admission and to use machine learning methods to predict probability of CRO and/or CPO carriage. METHODS We performed an observational cohort study of all patients admitted to the medical intensive care unit (MICU) or solid organ transplant (SOT) unit at The Johns Hopkins Hospital between July 1, 2016 and July 1, 2017. Admission perirectal swabs were screened for CROs and CPOs. More than 125 variables capturing preadmission clinical and demographic characteristics were collected from the electronic medical record (EMR) system. We developed models to predict colonization probabilities using decision tree learning. RESULTS Evaluating 2,878 admission swabs from 2,165 patients, we found that 7.5% and 1.3% of swabs were CRO and CPO positive, respectively. Organism and carbapenemase diversity among CPO isolates was high. Despite including many characteristics commonly associated with CRO/CPO carriage or infection, overall, decision tree models poorly predicted CRO and CPO colonization (C statistics, 0.57 and 0.58, respectively). In subgroup analyses, however, models did accurately identify patients with recent CRO-positive cultures who use proton-pump inhibitors as having a high likelihood of CRO colonization. CONCLUSIONS In this inpatient population, CRO carriage was infrequent but was higher than previously published estimates. Despite including many variables associated with CRO/CPO carriage, models poorly predicted colonization status, likely due to significant host and organism heterogeneity.

Abstract
In recent years, an increase in invasive VRE infections has been reported worldwide, including Germany. The most common gene encoding resistance to glycopeptides is VanA, but predominant VanB clones are emerging. Although neither the incidence rates nor the exact routes of nosocomial transmission of VRE are well established, screening and strict infection control measures, e.g. single room contact isolation, use of personal protective clothing by hospital staff and intensified surface disinfection for colonized individuals, are implemented in many hospitals. At the same time, the impact of VRE infection on mortality remains unclear, with current evidence being weak and contradictory. In this short review, we aim to give an overview on the current basis of evidence on the clinical effectiveness of infection control measures intended to prevent transmission of VRE and to put these findings into a larger perspective that takes further factors, e.g. VRE-associated mortality and impact on patient care, into account.
