Abstract
Importance Although recent guidelines recommend against performance of preoperative urine culture before nongenitourinary surgery, many clinicians still order preoperative urine cultures and prescribe antibiotics for treatment of asymptomatic bacteriuria in an effort to reduce infection risk. Objective To assess the association between preoperative urine culture testing and postoperative urinary tract infection (UTI) or surgical site infection (SSI), independent of baseline patient characteristics or type of surgery. Design, Setting, and Participants This cohort study analyzed surgical procedures performed from January 1, 2017, to December 31, 2019, at any of 112 US Department of Veterans Affairs (VA) medical centers. The cohort comprised VA enrollees who underwent major elective noncardiac, nonurological operations. Machine learning and inverse probability of treatment weighting (IPTW) were used to balance the characteristics between those who did and did not undergo a urine culture. Data analyses were performed between January 2023 and January 2024. Exposures Performance of urine culture within 30 days prior to surgery. Main Outcomes and Measures The 2 main outcomes were UTI and SSI occurring within 30 days after surgery. Weighted logistic regression was used to estimate odds ratios (ORs) for postoperative infection based on treatment status. Results A total of 250 389 VA enrollees who underwent 288 858 surgical procedures were included, with 88.9% (256 753) of surgical procedures received by males and 48.9% (141 340) received by patients 65 years or older. Baseline characteristics were well balanced among treatment groups after applying IPTW weights. Preoperative urine culture was performed for 10.5% of surgical procedures (30 384 of 288 858). The IPTW analysis found that preoperative urine culture was not associated with SSI (adjusted OR [AOR], 0.99; 95% CI, 0.90-1.10) or postoperative UTI (AOR, 1.18; 95% CI, 0.98-1.40). In analyses limited to orthopedic surgery and neurosurgery as a proxy for prosthetic implants, the adjusted risks for UTI and SSI were also not associated with preoperative urine culture performance. Conclusions and Relevance This cohort study found no association between performance of a preoperative urine culture and lower risk of postoperative UTI or SSI. The results support the deimplementation of urine cultures and associated antibiotic treatment prior to surgery, even when using prosthetic implants.

Abstract
BACKGROUND In the treatment of methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections (BSIs), vancomycin stands as the prevalent therapeutic agent. Daptomycin remains an alternative antibiotic to treat MRSA BSIs in cases where vancomycin proves ineffective. However, studies have conflicted on whether daptomycin is more effective than vancomycin among patients with MRSA BSI. OBJECTIVE To compare the effectiveness of daptomycin and vancomycin for the prevention of mortality among adult patients with MRSA BSI. METHODS Systematic searches of databases were performed, including Embase, PubMed, Web of Science, and Cochrane Library. The Newcastle Ottawa Scale (NOS) and Revised Cochrane risk-of-bias tool for randomized trials (RoB 2) were used to assess the quality of individual observational and randomized control studies, respectively. Pooled odd ratios were calculated using random effects models. RESULTS Twenty studies were included based on a priori set inclusion and exclusion criteria. Daptomycin treatment was associated with non-significant lower mortality odds, compared to vancomycin treatment (OR = 0.81; 95% CI, 0.62, 1.06). Sub-analyses based on the time patients were switched from another anti-MRSA treatment to daptomycin demonstrated that switching to daptomycin within 3 or 5 days was significantly associated with 55% and 45% decreased odds of all-cause mortality, respectively. However, switching to daptomycin any time after five days of treatment was not significantly associated with lower odds of mortality. Stratified analysis based on vancomycin minimum inhibitory concentration (MIC) revealed that daptomycin treatment among patients infected with MRSA strains with MIC≥1 mg/L was significantly associated with 40% lower odds of mortality compared to vancomycin treatment. CONCLUSION Compared with vancomycin, an early switch from vancomycin to daptomycin was significantly associated with lower odds of mortality. In contrast, switching to daptomycin at any time only showed a trend towards reduced mortality, with a non-significant association. Therefore, the efficacy of early daptomycin use over vancomycin against mortality among MRSA BSIs patients may add evidence to the existing literature in support of switching to daptomycin early over remaining on vancomycin. More randomized and prospective studies are needed to assess this association.

Abstract
BACKGROUND Atrial fibrillation (AF) and/or atrial flutter (AFL) with rapid ventricular response (RVR) is a condition that often requires urgent treatment. Although guidelines have recommendations regarding chronic rate control therapy, recommendations on the best choice for acute heart rate (HR) control in RVR are unclear. METHODS A systematic search across multiple databases was performed for studies evaluating the outcome of HR control (defined as HR less than 110 bpm and/or 20% decrease from baseline HR). Included studies evaluated AF and/or AFL with RVR in a hospital setting, with direct comparison between intravenous (IV) diltiazem and metoprolol and excluded cardiac surgery and catheter ablation patients. Hypotension (defined as systolic blood pressure less than 90 mmHg) was measured as a secondary outcome. Two authors performed full-text article review and extracted data, with a third author mediating disagreements. Random effects models utilizing inverse variance weighting were used to calculate odds ratios (OR) and 95% confidence intervals (CI). Heterogeneity was assessed using the I2 test. RESULTS A total of 563 unique titles were identified through the systematic search, of which 16 studies (7 randomized and 9 observational) were included. In our primary analysis of HR control by study type, IV diltiazem was found to be more effective than IV metoprolol for HR control in randomized trials (OR 4.75, 95% CI 2.50-9.04 with I2 = 14%); however, this was not found for observational studies (OR 1.26, 95% CI 0.89-1.80 with I2 = 55%). In an analysis of observational studies, there were no significant differences between the two drugs in odds of hypotension (OR 1.12, 95% CI 0.51-2.45 with I2 = 18%). CONCLUSION While there was a trend toward improved HR control with IV diltiazem compared with IV metoprolol in randomized trials, this was not seen in observational studies, and there was no observed difference in hypotension between the two drugs.

Abstract
This document introduces and explains common implementation concepts and frameworks relevant to healthcare epidemiology and infection prevention and control and can serve as a stand-alone guide or be paired with the "SHEA/IDSA/APIC Compendium of Strategies to Prevent Healthcare-Associated Infections in Acute Care Hospitals: 2022 Updates," which contain technical implementation guidance for specific healthcare-associated infections. This Compendium article focuses on broad behavioral and socio-adaptive concepts and suggests ways that infection prevention and control teams, healthcare epidemiologists, infection preventionists, and specialty groups may utilize them to deliver high-quality care. Implementation concepts, frameworks, and models can help bridge the "knowing-doing" gap, a term used to describe why practices in healthcare may diverge from those recommended according to evidence. It aims to guide the reader to think about implementation and to find resources suited for a specific setting and circumstances by describing strategies for implementation, including determinants and measurement, as well as the conceptual models and frameworks: 4Es, Behavior Change Wheel, CUSP, European and Mixed Methods, Getting to Outcomes, Model for Improvement, RE-AIM, REP, and Theoretical Domains.

Abstract
BACKGROUND Refugees have a high prevalence of obesity post resettlement, but few studies have compared their risk of obesity to those of the host population. We systematically investigated the association between refugee status and obesity after resettlement in a high-income nation. METHODS We searched PubMed, Embase, OpenGrey and bibliographies of retrieved articles, with no date, location, and language restrictions, for observational studies assessing obesity rates in resettled refugees compared to the host population. RESULTS Nine studies were analyzed. We found no evidence of increased risk of obesity among refugees compared to the host population, with significant heterogeneity across studies. However, the risk of obesity among refugee men were significantly lower than the host population. DISCUSSION The heterogeneity between studies calls for more high-quality research to examine the risk of obesity among refugees compared to the host population in high-income countries. This will enable results to be pooled to provide more decisive evidence about obesity trends among refugees post migration in a high-income nation.

Abstract
Importance While current evidence has demonstrated a surgical site infection (SSI) prevention bundle consisting of preoperative Staphylococcus aureus screening, nasal and skin decolonization, and use of appropriate perioperative antibiotic based on screening results can decrease rates of SSI caused by S aureus, it is well known that interventions may need to be modified to address facility-level factors. Objective To assess the association between implementation of an SSI prevention bundle allowing for facility discretion regarding specific component interventions and S aureus deep incisional or organ space SSI rates. Design, Setting, and Participants This quality improvement study was conducted among all patients who underwent coronary artery bypass grafting, cardiac valve replacement, or total joint arthroplasty (TJA) at 11 Veterans Administration hospitals. Implementation of the bundle was on a rolling basis with the earliest implementation occurring in April 2012 and the latest implementation occurring in July 2017. Data were collected from January 2007 to March 2018 and analyzed from October 2020 to June 2023. Interventions Nasal screening for S aureus; nasal decolonization of S aureus carriers; chlorhexidine bathing; and appropriate perioperative antibiotic prophylaxis according to S aureus carrier status. Facility discretion regarding how to implement the bundle components was allowed. Main Outcomes and Measures The primary outcome was deep incisional or organ space SSI caused by S aureus. Multivariable logistic regression with generalized estimating equation (GEE) and interrupted time-series (ITS) models were used to compare SSI rates between preintervention and postintervention periods. Results Among 6696 cardiac surgical procedures and 16 309 TJAs, 95 S aureus deep incisional or organ space SSIs were detected (25 after cardiac operations and 70 after TJAs). While the GEE model suggested a significant association between the intervention and decreased SSI rates after TJAs (adjusted odds ratio, 0.55; 95% CI, 0.31-0.98), there was not a significant association when an ITS model was used (adjusted incidence rate ratio, 0.88; 95% CI, 0.32-2.39). No significant associations after cardiac operations were found. Conclusions and Relevance Although this quality improvement study suggests an association between implementation of an SSI prevention bundle and decreased S aureus deep incisional or organ space SSI rates after TJAs, it was underpowered to see a significant difference when accounting for changes over time.

Abstract
Background: Current guidelines recommend against placement of implantable cardioverter defibrillators in patients with a life expectancy less than one year. These patients may benefit from early palliative care services; however, identifying this population is challenging. Objective: Determine whether a validated prognostic tool, based on patient factors and health care utilization from electronic medical records, accurately predicts one-year mortality at the time of implantable cardioverter defibrillator placement. Design: We used the United States (U.S.) Veterans Administration's "Care Assessment Needs" one-Year Mortality Score to identify patients at high risk of mortality (score ≥95) before their procedure. Data were extracted from the Corporate Data Warehouse. Logistic regression was used to assess the odds of mortality at different score levels. Setting/Subjects: Patients undergoing a new implantable cardioverter defibrillator procedure between October 1, 2015 and September 30, 2017 in the U.S. Veterans Administration. Results: Of 3194 patients with a new implantable cardioverter defibrillator placed, 657 (21.8%) had a score ≥95. The mortality rate among these patients was 151/657 (22.9%) compared with 281/3194 (8.8%) for all patients undergoing a new implantable cardioverter defibrillator procedure. Patients with a score ≥95 had 14.0 (95% confidence interval 8.0-24.4) higher odds of death within one year of the procedure compared with those with a score ≤60. Conclusions: The "Care Assessment Needs" Score is a valid predictor of one-year mortality following implantable cardioverter defibrillator procedures. Integrating its use into the management of Veterans Administration (VA) patients considering implantable cardioverter defibrillators may improve shared decision making and engagement with palliative care.

Abstract
BACKGROUND AND OBJECTIVE Emerging evidence suggests a role for diet in multiple sclerosis (MS) care; however, owing to methodological issues and heterogeneity of dietary interventions in preliminary trials, the current state of evidence does not support dietary recommendations for MS. The objective of this study was to assess the efficacy of different dietary approaches on MS-related fatigue and quality of life (QoL) through a systematic review of the literature and network meta-analysis (NMA). METHODS Electronic database searches were performed in May 2021. Inclusion criteria were (1) randomized trial with a dietary intervention, (2) adults with definitive MS based on McDonald criteria, (3) patient-reported outcomes for fatigue and/or QoL, and (4) minimum intervention period of 4 weeks. For each outcome, standardized mean differences (SMDs) were calculated and included in random effects NMA to determine the pooled effect of each dietary intervention relative to each of the other dietary interventions. The protocol was registered at PROSPERO (CRD42021262648). RESULTS Twelve trials comparing 8 dietary interventions (low-fat, Mediterranean, ketogenic, anti-inflammatory, Paleolithic, fasting, calorie restriction, and control [usual diet]), enrolling 608 participants, were included in the primary analysis. The Paleolithic (SMD -1.27; 95% CI -1.81 to -0.74), low-fat (SMD -0.90; 95% CI -1.39 to -0.42), and Mediterranean (SMD -0.89; 95% CI -1.15 to -0.64) diets showed greater reductions in fatigue compared with control. The Paleolithic (SMD 1.01; 95% CI 0.40-1.63) and Mediterranean (SMD 0.47; 95% CI 0.08-0.86) diets showed greater improvements in physical QoL compared with control. For improving mental QoL, the Paleolithic (SMD 0.81; 95% CI 0.26-1.37) and Mediterranean (SMD 0.36; 95% CI 0.06-0.65) diets were more effective compared with control. However, the NutriGRADE credibility of evidence for all direct comparisons is very low because of most of the included trials having high or moderate risk of bias, small sample sizes, and the limited number of studies included in this NMA. DISCUSSION Several dietary interventions may reduce MS-related fatigue and improve physical and mental QoL; however, because of the limitations of this NMA, which are driven by the low quality of the included trials, these findings must be confirmed in high-quality, randomized, controlled trials.

Abstract
BACKGROUND Carbapenem-resistant Enterobacterales bloodstream infections (CRE-BSI) increase mortality three-fold compared with carbapenem-susceptible bloodstream infections. Because these infections are rare, there is a paucity of information on mortality associated with different treatment regimens. This study examines treatment regimens and association with in-hospital, 30 day and 1 year mortality risk for patients with CRE-BSI. METHODS This retrospective cohort study identified hospitalized patients within the Veteran Affairs (VA) from 2013 to 2018 with a positive CRE blood culture and started antibiotic treatment within 5 days of culture. Primary outcomes were in-hospital, 30 day and 1 year all-cause mortality. Secondary outcomes were healthcare costs at 30 days and 1 year and Clostridioides difficile infection 6 weeks post culture date. The propensity for receiving each treatment regimen was determined. Multivariable regression assessed the association between treatment and outcomes. RESULTS There were 393 hospitalized patients from 2013 to 2018 included in the study. The cohort was male (97%) and elderly (mean age 71.0 years). Carbapenems were the most prescribed antibiotics (47%). In unadjusted analysis, ceftazidime/avibactam was associated with a lower likelihood of 30 day and 1 year mortality. After adjusting, ceftazidime/avibactam had a 30 day mortality OR of 0.42 (95% CI 0.17-1.02). No difference was found in C. difficile incidence at 6 weeks post-infection or total costs at 30 days or 1 year post culture date by any treatments. CONCLUSIONS In hospitalized veterans with CRE-BSI, none of the treatments were shown to be associated with all-cause mortality. Ceftazidime/avibactam trended towards protectiveness against 30 day and 1 year all-cause mortality. Use of ceftazidime/avibactam should be encouraged for treatment of CRE-BSI.

Abstract
Abstract
Objectives
Rifampin is recommended as adjunctive therapy for patients with a Staphylococcus aureus prosthetic joint infection (PJI) managed with debridement, antibiotics, and implant retention (DAIR) with no solid consensus on the optimal duration of therapy. Our study assessed the effectiveness and optimal duration of rifampin for S. aureus PJI using Veterans Health Administration (VHA) data.
Methods
We conducted a retrospective cohort study of patients with S. aureus PJI managed with DAIR between 2003 and 2019 in VHA hospitals. Patients who died within 14 days after DAIR were excluded. The primary outcome was a time to microbiological recurrence from 15 days up to two years after DAIR. Rifampin use was analyzed as a time-varying exposure, and time-dependent hazard ratios (HRs) for recurrence were calculated according to the duration of rifampin treatment.
Results
Among 4,624 patients, 842 (18.2%) received at least one dose of rifampin. 1785 (38.6%) experienced recurrence within two years. Rifampin treatment was associated with significantly lower HRs for recurrence during the first 90 days of treatment (HR 0.60; 95%CI 0.45-0.79) and between days 91 and 180 (HR 0.16; 95%CI 0.04-0.66) but no statistically significant protective effect was observed with longer than 180 days (HR 0.57; 95%CI 0.18-1.81). The benefit of rifampin was observed for subgroups including knee PJI, MSSA or MRSA infection, and early or late PJI.
Conclusions
This study supports current guidelines which recommend adjunctive rifampin use for up to six months among patients with S. aureus PJI treated with DAIR.

Abstract
BACKGROUND The effect of nonobstructive chronic bronchitis (CB) on mortality is unclear. RESEARCH QUESTION Is nonobstructive CB associated with increased all-cause mortality? STUDY DESIGN AND METHODS We conducted a systematic literature review and meta-analysis to assess the association of nonobstructive CB and all-cause mortality. We searched for articles that included both CB and mortality in the title, abstract, or both in PubMed and EMBASE. We excluded studies in which participants demonstrated obstructive spirometry findings and studies in which CB and mortality were not defined. We used the Newcastle-Ottawa Quality Assessment Scale to assess study quality. We pooled adjusted hazard ratios (HRs) using the random effects model and inverse variance weighting. We conducted stratified analysis by the definition of CB and smoking status. We used Cochran's Q and I2 to assess for heterogeneity. We assessed publication bias by visual inspection of a funnel plot. RESULTS Of 5,014 titles identified, eight fulfilled the inclusion and exclusion criteria. Overall nonobstructive CB was associated with all-cause mortality (HR, 1.37; 95% CI, 1.26-1.50) with no statistically significant heterogeneity (P = .14; I2 = 29%). Nonobstructive CB was associated with increased mortality in studies that defined CB as any respiratory symptoms (broad definition; HR, 1.28; 95% CI, 1.10-1.48; I2 = 0%) as well as in the rest of the studies (HR, 1.40; 95% CI, 1.26-1.56; I2 = 37%). Nonobstructive CB was associated with increased mortality in ever smokers (HR, 1.49; 95% CI, 1.35-1.64; I2 = 0%), but was not associated with increased mortality in never smokers (HR, 1.22; 95% CI, 0.90-1.66), and moderate heterogeneity was found (P = .10; I2 = 49%). The funnel plot did not indicate evidence of a publication bias because it showed symmetrical distribution of studies. INTERPRETATION Nonobstructive CB is associated with increased all-cause mortality, and this association seems to be present only in current and former smokers. Further research should investigate whether this high-risk population may benefit from early therapeutic intervention. TRIAL REGISTRY PROSPERO; No.: CRD42021253596; URL: www.crd.york.ac.uk/prospero.

Abstract
Background: This meta-analysis aims to evaluate the effectiveness of combination therapy for treating MSSA bacteremia. Methods: We searched Ovid MEDLINE, EMBASE, Cochrane CENTRAL, and clinicaltrials.gov for studies including adults with MSSA bacteremia. The monotherapy group used a first-line antibiotic active against MSSA and the combination group used a first-line antibiotic plus additional antibiotic/s. The primary outcome was all-cause mortality. Secondary outcomes included persistent bacteremia, duration of bacteremia, relapse, and adverse events. Random-effects models with inverse variance weighting were used to estimate pooled risk ratios (pRR). Heterogeneity was assessed using the I2 value and the Cochrane’s Q statistic. Results: A total of 12 studies (6 randomized controlled trials [RCTs]) were included. Combination therapy did not significantly reduce 30-day mortality (pRR 0.92, 95% CI, 0.70–1.20), 90-day mortality (pRR 0.89, 95% CI, 0.74–1.06), or any-time mortality (pRR 0.91, 95% CI, 0.76–1.08). Among patients with deep-seated infections, adjunctive rifampicin may reduce 90-day mortality (3 studies with moderate-high risk of bias; pRR 0.62, 95% CI, 0.42–0.92). For secondary outcomes, combination therapy decreased the risk of relapse (pRR 0.38, 95% CI, 0.22–0.66), but this benefit was not maintained when pooling RCTs (pRR 0.54, 95% CI, 0.12–2.51). Combination therapy was associated with an increased risk of adverse events (pRR 1.74, 95% CI, 1.31–2.31). Conclusions: Combination therapy not only did not decrease mortality in patients with MSSA bacteremia, but also increased the risk of adverse events. Combination therapy may reduce the risk of relapse, but additional high-quality studies are needed.

Abstract
Abstract
Background
Enterococcal bacteremia carries significant mortality. While multiple studies have evaluated the impact of infectious disease consultation (IDC) on this condition, these studies were limited by the low numbers of patients enrolled. This systemic literature review and meta-analysis were conducted to determine whether IDC was associated with a mortality benefit among patients with enterococcal bacteremia.
Methods
We performed a systematic literature search using 5 databases for studies evaluating IDC among patients with enterococcal bacteremia. We conducted a meta-analysis to assess whether IDC was associated with reduced mortality. Random-effect models were used to calculated pooled odds ratios (pORs). Heterogeneity was evaluated using I2 estimation and the Cochrane Q statistic test.
Results
The systemic literature review revealed 6496 reports, from which 18 studies were evaluated in the systemic literature review and 16 studies in the meta-analysis. When all studies were pooled, the association between IDC and mortality was not statistically significant with a pOR of 0.81 (95% CI, 0.61-1.08) and there was substantial heterogeneity (I2=58%). When the studies were limited to those reporting multivariate analysis including IDC, there was a significant protective effect of IDC (pOR=0.40; 95% CI, 0.24-0.68) without heterogeneity (I2=0%). Some studies also showed additional benefits to IDC, including appropriate antibiotic therapy, and improved diagnostic use.
Conclusions
IDC was associated with 60% lower odds of mortality when patients were well-matched, potentially through improvement in the care for patients with enterococcal bacteremia. IDC should be considered a part of routine care for patients with enterococcal bacteremia.

Abstract
OBJECTIVES We aimed to assess the short-term effectiveness of COVID-19 vaccines among immunocompromised patients to prevent laboratory-confirmed symptomatic COVID-19 infection. METHODS Systematic review and meta-analysis. We calculated the pooled diagnostic odds ratio [DOR] (95% CI) for COVID-19 infection between immunocompromised patients and healthy people or those with stable chronic medical conditions. VE was estimated as 100% x (1-DOR). We also investigated the rates of developing anti-SARS-CoV-2 spike protein IgG between the 2 groups. RESULTS Twenty studies evaluating COVID-19 vaccine response, and four studies evaluating VE were included in the meta-analysis. The pooled DOR for symptomatic COVID-19 infection in immunocompromised patients was 0.296 (95% CI: 0.108-0.811) with an estimated VE of 70.4% (95% CI: 18.9%- 89.2%). When stratified by diagnosis, IgG antibody levels were much higher in the control group compared to immunocompromised patients with solid organ transplant (pOR 232.3; 95% Cl: 66.98-806.03), malignant diseases (pOR 42.0, 95% Cl: 11.68-151.03), and inflammatory rheumatic diseases (pOR 19.06; 95% Cl: 5.00-72.62). CONCLUSIONS We found COVID-19 mRNA vaccines were effective against symptomatic COVID-19 among the immunocompromised patients but had lower VE compared to the controls. Further research is needed to understand the discordance between antibody production and protection against symptomatic COVID-19 infection.

Abstract
Background Despite a strong evidence base and clinical guidelines specifically recommending against prolonged post-procedural antimicrobial use, studies indicate that the practice is common following cardiac device procedures. Formative evaluations conducted by the study team suggest that inappropriate antimicrobial use may be driven by information silos that drive provider belief that antimicrobials are not harmful, in part due to lack of complete feedback about all types of clinical outcomes. De-implementation is recognized as an important area of research that can lead to reductions in unnecessary, wasteful, or harmful practices, such as excess antimicrobial use following cardiac device procedures; however, investigations into strategies that lead to successful de-implementation are limited. The overarching hypothesis to be tested in this trial is that a bundle of implementation strategies that includes audit and feedback about direct patient harms caused by inappropriate prescribing can lead to successful de-implementation of guideline-discordant care. Methods We propose a hybrid type III effectiveness-implementation stepped-wedge intervention trial at three high-volume, high-complexity VA medical centers. The main study intervention (an informatics-based, real-time audit-and-feedback tool) was developed based on learning/unlearning theory and formative evaluations and guided by the integrated-Promoting Action on Research Implementation in Health Services (i-PARIHS) Framework. Elements of the bundled and multifaceted implementation strategy to promote appropriate prescribing will include audit-and-feedback reports that include information about antibiotic harms, stakeholder engagement, patient and provider education, identification of local champions, and blended facilitation. The primary study outcome is adoption of evidence-based practice (de-implementation of inappropriate antimicrobial use). Clinical outcomes (cardiac device infections, acute kidney injuries and Clostridioides difficile infections) are secondary. Qualitative interviews will assess relevant implementation outcomes (acceptability, adoption, fidelity, feasibility). Discussion De-implementation theory suggests that factors that may have a particularly strong influence on de-implementation include strength of the underlying evidence, the complexity of the intervention, and patient and provider anxiety and fear about changing an established practice. This study will assess whether a multifaceted intervention mapped to identified de-implementation barriers leads to measurable improvements in provision of guideline-concordant antimicrobial use. Findings will improve understanding about factors that impact successful or unsuccessful de-implementation of harmful or wasteful healthcare practices.

Abstract
Abstract
Background
Staphylococcus aureus surgical site infection (SSI) is common and devastating clinically. Pre-operative decolonization is associated with reduced incidence, but has been variably adopted due to barriers implementing high-efficacy prevention bundles, including unintentional non-compliance applying intra-nasal mupirocin by patients at home. Three Veterans Affairs (VA) facilities attempted to implement an alternate evidence-based SSI prevention program that included intranasal povidone-iodine used in the pre-operative setting to reduce challenging patient-burden steps and to overcome other mupirocin barriers. Our objective was to identify strategies used for successful implementation of intranasal povidone-iodine.
Methods
We conducted pre- and post-implementation semi-structured interviews and site visits at three VA hospitals. Participants included surgery and clinic staff (e.g., nurses, physicians, care managers), infection control staff, and administrative leadership. Interviews were audio recorded and transcribed. Our interdisciplinary team performed a deductive and inductive consensus-based analysis.
Results
Implementation of this SSI prevention process was successful when nurse champions drove the implementation. Qualitative interviews indicate that nurses used a variety of strategies and messages variant on their audience. Nurse-driven facilitators included: key leadership buy-in and strategic decisions about timing and setting of implementation (i.e., start implementation in units with likely early adopters then when project is working well circle back to the early detractors). The primary implementation barrier identified was lack of a champion. One site stated that in the absence of a champion, a mandate or top-down approach may be needed for implementation at their facility.
Conclusion
Nurse champions facilitated successful SSI prevention process implementation. Nurses used strategies and approaches dependent on their knowledge and understanding of the stakeholders and setting to obtain buy-in. Future implementation of new clinical practices should consider utilizing nurse champions to promote uptake.

Abstract
Background 2-stage exchange (2SE) surgery is often used to treat chronic prosthetic joint infections (PJI). IDSA guidelines do not recommend oral antibiotic suppression after 2SE. However, a recent randomized trial suggested that oral antibiotics for 3 months after arthroplasty reimplantation may prevent recurrent PJI. Objective: To compare rates of treatment failure (i.e., recurrent PJI) and adverse reactions (ARs) among patients who received < 1 month of antibiotics directly after reimplantation to those who received 1-3 months of antibiotics following reimplantation (extended antibiotics). Methods This retrospective cohort study included patients with hip, knee, or shoulder PJI who underwent 2SE at 83 VA hospitals between the years 2003-2017. PJI was defined using administrative codes and microbiology data. Patients were followed for 5 years to assess treatment failure (TF) and ARs. TF was defined as recurrent PJI, debridement, or reoperation. ARs included Clostridioides difficile infections (CDI), or antibiotic associated diarrhea (AAD) during or 72 hours after antibiotics. Chi-square tests were used to compare outcomes. Cumulative incidence function curves were created to compare TF rates between those who did and did not receive extended antibiotic treatment, incorporating the competing risks of TF and death. Results Of the 433 patients, most (97%) received < 1 month of oral antibiotics and 3% received extended antibiotics. The 15 patients who received extended antibiotics had similar rates of TF and ARs compared with patients who received < 1 month of oral antibiotics (Table). However, there was a trend toward higher rates of CDI (6.7% vs. 3.8%) and AAD (13.3% vs. 9.6%) among those who received extended antibiotics. There was no difference in TF comparing extended antibiotics with < 1 month of antibiotics, accounting for death (Figure).

![]()
Conclusion Few patients received extended oral antibiotics in the study period. There were no statistically significant differences in TF or ARs between the 2 groups. Yet, there was a trend toward higher rates of ARs among the extended antibiotic group. Future prospective studies should assess both the potential benefits and ARs associated with extended antibiotics among patients undergoing 2SE surgery. Disclosures Marin L.

Abstract
INTRODUCTION Approximately 38% of haemodialysis patients carry Staphylococcus aureus in their noses, and carriers have a nearly four-fold increased risk of S. aureus access-related bloodstream infections (BSIs) compared with non-carriers. Our objective is to determine the clinical efficacy and effectiveness of a novel intervention using nasal povidone-iodine (PVI) to prevent BSIs among patients in haemodialysis units. We will survey patients and conduct qualitative interviews with healthcare workers to identify barriers and facilitators to implementing the intervention. METHODS AND ANALYSIS We will perform an open-label, stepped-wedge cluster randomised trial to assess the effectiveness of nasal PVI compared with standard care. Sixteen outpatient haemodialysis units will participate in the study. The 3-year trial period will be divided into a 4-month baseline period and eight additional 4-month time blocks. The primary outcome of the study will be S. aureus BSI, defined as a S. aureus positive blood culture collected in the outpatient setting or within one calendar day after a hospital admission. The study team will evaluate characteristics of individual patients and the clusters by exposure status (control or intervention) to assess the balance between groups, and calculate descriptive statistics such as average responses separately for control and intervention survey questions. ETHICS AND DISSEMINATION This study has received IRB approval from all study sites. A Data Safety and Monitoring Board will monitor this multicentre clinical trial. We will present our results at international meetings. The study team will publish findings in peer-reviewed journals and make each accepted peer-reviewed manuscript publicly available. TRIAL REGISTRATION NUMBER NCT04210505.

Abstract
BACKGROUND Most articles on hand hygiene report either overall compliance or compliance with specific hand hygiene moments. These moments vary in the level of risk to patients if healthcare workers (HCWs) are noncompliant. We assessed how task type affected HCWs' hand hygiene compliance. METHODS We linked consecutive tasks individual HCWs performed during the Strategies to Reduce Transmission of Antimicrobial Resistant Bacteria in Intensive Care Units (STAR*ICU) study into care sequences and identified task pairs-2 consecutive tasks and the intervening hand hygiene opportunity. We defined tasks as critical and/or contaminating. We determined the odds of critical and contaminating tasks occurring, and the odds of hand hygiene compliance using logistic regression for transition with a random effect adjusting for isolation precautions, glove use, HCW type, and compliance at prior opportunities. RESULTS Healthcare workers were less likely to do hand hygiene before critical tasks than before other tasks (adjusted odds ratio [aOR], 0.97 [95% confidence interval {CI}, .95-.98]) and more likely to do hand hygiene after contaminating tasks than after other tasks (aOR, 1.12 [95% CI, 1.10-1.13]). Nurses were more likely to perform both critical and contaminating tasks, but nurses' hand hygiene compliance was better than physicians' (aOR, 0.94 [95% CI, .91-.97]) and other HCWs' compliance (aOR, 0.87 [95% CI, .87-.94]). CONCLUSIONS Healthcare workers were more likely to do hand hygiene after contaminating tasks than before critical tasks, suggesting that habits and a feeling of disgust may influence hand hygiene compliance. This information could be incorporated into interventions to improve hand hygiene practices, particularly before critical tasks and after contaminating tasks.

Abstract
BACKGROUND In October 2007, Veterans Affairs (VA) launched a nationwide effort to reduce methicillin-resistant Staphylococcus aureus (MRSA) transmission called the National MRSA Prevention Initiative. Although the initiative focused on MRSA, recent evidence suggests that it also led to a significant decrease in hospital-onset (HO) gram-negative rod (GNR) bacteremia, vancomycin-resistant Enterococci (VRE), and Clostridioides difficile infections. The objective of this analysis was to evaluate the cost-effectiveness and the budget impact of the initiative taking into account MRSA, GNR, VRE, and C. difficile infections. METHODS We developed an economic model using published data on the rate of MRSA hospital-acquired infections (HAIs) and HO-GNR bacteremia in the VA from October 2007 to September 2015, estimates of the attributable cost and mortality of these infections, and the costs associated with the intervention obtained through a microcosting approach. We explored several different assumptions for the rate of infections that would have occurred if the initiative had not been implemented. Effectiveness was measured in life-years (LYs) gained. RESULTS We found that during fiscal years 2008-2015, the initiative resulted in an estimated 4761-9236 fewer MRSA HAIs, 1447-2159 fewer HO-GNR bacteremia, 3083-3602 fewer C. difficile infections, and 2075-5393 fewer VRE infections. The initiative itself was estimated to cost $561 million over this 8-year period, whereas the cost savings from prevented MRSA HAIs ranged from $165 to $315 million and from prevented HO-GNR bacteremia, CRE and C. difficile infections ranged from $174 to $200 million. The incremental cost-effectiveness of the initiative ranged from $12 146 to $38 673/LY when just including MRSA HAIs and from $1354 to $4369/LY when including the additional pathogens. The overall impact on the VA's budget ranged from $67 to$195 million. CONCLUSIONS An MRSA surveillance and prevention strategy in VA may have prevented a substantial number of infections from MRSA and other organisms. The net increase in cost from implementing this strategy was quite small when considering infections from all types of organisms. Including spillover effects of organism-specific prevention efforts onto other organisms can provide a more comprehensive evaluation of the costs and benefits of these interventions.

Abstract
BACKGROUND Patients with methicillin-resistant Staphylococcus aureus bloodstream infections (MRSA BSI) usually receive initial treatment with vancomycin but may be switched to daptomycin for definitive therapy, especially if treatment failure is suspected. Our objective was to evaluate the effectiveness of switching from vancomycin to daptomycin compared with remaining on vancomycin among patients with MRSA BSI. METHODS Patients admitted to 124 Veterans Affairs Hospitals who experienced MRSA BSI and were treated with vancomycin during 2007-2014 were included. The association between switching to daptomycin and 30-day mortality was assessed using Cox regression models. Separate models were created for switching to daptomycin any time during the first hospitalization and for switching within 3 days of receiving vancomycin. RESULTS In total, 7411 patients received vancomycin for MRSA BSI. Also, 606 (8.2%) patients switched from vancomycin to daptomycin during the first hospitalization, and 108 (1.5%) switched from vancomycin to daptomycin within 3 days of starting vancomycin. In the multivariable analysis, switching to daptomycin within 3 days was significantly associated with lower 30-day mortality (hazards ratio [HR] = 0.48; 95% confidence interval [CI]: .25, .92). However, switching to daptomycin at any time during the first hospitalization was not significantly associated with 30-day mortality (HR: 0.87; 95% CI: .69, 1.09). CONCLUSIONS Switching to daptomycin within 3 days of initial receipt of vancomycin is associated with lower 30-day mortality among patients with MRSA BSI. This benefit was not seen when the switch occurred later. Future studies should prospectively assess the benefit of early switching from vancomycin to other anti-MRSA antibiotics.

Abstract
Ceftolozane-tazobactam (C/T), ceftazidime-avibactam (C/A), and meropenem/vaborbactam (M/V) are new beta-lactam/beta-lactamase combination antibiotics commonly used to treat multidrug-resistant Pseudomonas aeruginosa (MDRPA) and carbapenem-resistant Enterobacteriaceae (CRE) infections. This review reports the clinical success rates for C/T, C/A, and M/V. PubMed and EMBASE were searched from January 1, 2012, through September 2, 2020, for publications detailing the use of C/T, C/A, and M/V. A meta-analysis determined the pooled effectiveness of C/T, C/A, and M/V. The literature search returned 1950 publications; 29 publications representing 1620 patients were retained. Pneumonia was the predominant infection type (49.8%). MDRPA was the major pathogen treated (65.3%). The pooled clinical success rate was 73.3% (95% CI, 68.9%-77.5%). C/T, C/A, or M/V resistance was reported in 8.9% of the population. These antibiotics had a high clinical success rate in patients with complicated infections and limited treatment options. Larger studies comparing C/T, C/A, and M/V against other antibiotic regimens are needed.

Abstract
Abstract
Background
Community-acquired Staphylococcus aureus bacteremia (CA SAB) is a common infection with high mortality. Ten Oever et al. recently used expert consensus methods to develop a set of 25 quality indicators for SAB care in five domains (i.e., follow up blood cultures, echocardiography, non-antibiotic interventions including source control, antibiotic treatment, and other management aspects). Associations between these quality indicators and patient outcomes have not been evaluated. We assessed associations between proposed quality indicators and all-cause 30-day mortality among patients with CA SAB.
Methods
We conducted a nested case-control study within a described national multicenter cohort of patients with SAB in the Veterans Health Administration (VHA). The cohort included 2,093 patients who were: 1) admitted to acute care hospitals between 1/2012 and 12/2014 for CA SAB (the first positive blood culture before or within 48 hours of admission with no recent healthcare exposure); 2) survived at least 96 hours after the SAB onset. We identified paired cases (who died within 30 days) and controls (who survived an equal time), matched 1:1 for age (+/- 5 years), gender, admission year and month, and methicillin susceptibility of isolates. We reviewed charts to extract information for quality indicators. We estimated associations between quality indicators and mortality using logistic regression, adjusting for patient demographics and comorbidity.
Results
164 patients (82 cases and 82 controls) were included. The median patient age was 68.5 (IQR: 62–80) years, and 74 (45.1%) had methicillin-resistant isolates. All patients received at least one domain of quality indicator (median: 3 [IQR: 2–4]). When analyzed individually, only two domains (follow-up blood cultures: OR 0.27 [95% CI: 0.11–0.68]; source control: OR: 0.13 [0.05–0.31]) were associated with mortality. There was a dose-response relationship in which more domains received was associated with decreased mortality (Figure).
Association Between the Number of Satisfied Quality Indicator Domains and All-Cause 30-day Mortality
Conclusion
Among patients with CA-SAB, the number of satisfied quality indicator domains was associated with 30-day mortality with a dose-response relationship. This finding supports the relevance of these quality indicators for SAB management.

Abstract
Background Morbidity and mortality from candidemia remain unacceptably high. While infectious disease consultation (IDC) is known to lower the mortality from Staphylococcus aureus bacteremia, little is known on the impact of IDC in candidemia. Methods We conducted a retrospective observational cohort study of candidemia patients at a large tertiary care hospital between 2015 and 2019. All patients aged ≥18 years with blood cultures positive for Candida species were included. We only included the first episode of candidemia. Exclusion criteria were death or transfer to the palliative care unit within 48 hours from the time cultures became positive. The crude mortality rate was compared between those with IDC and without IDC. Then, we systematically searched five publication-databases through February 2020 and performed a meta-analysis of the impact of IDC on mortality of patients with candidemia. The study protocol has been submitted to the International Prospective Register for Systematic Reviews (PROSPERO) database (ID 156939) on April 2020. Results A total of 151 patients at our institution met the inclusion criteria, 129 (85%) of whom received IDC. Thirty-day, and 90-day mortality rates were significantly lower in the IDC group (18% vs 50%, P = .002; 23% vs 50%, P = .0022, respectively). Our systematic literature review returned 216 reports, of which, 13 studies including ours fulfilled the inclusion criteria. Among the 13 studies with a total 3687 patients, IDC was performed in 49% of patients. Mortality numbers were available in 10 studies. Overall mortality was 38.2% with a significant difference in favor of the IDC group (28.4% and 47.6%) with a pooled relative risk of 0.41 [95% Cl 0.35-0.49]. Ophthalmology referral (61%; 790/1279 and 21%; 273/1304, P < 0.001), echocardiogram (54%; 662/1219 and 28%; 369/1296, P < 0.001), and central line removal (78%; 830/1069 and 61%; 686/1116, P < 0.02) were performed more frequently among patients receiving IDC. Overall mortality ![]()
Conclusion This study is the first systematic literature review and meta-analysis to evaluate the association between IDC and candidemia mortality. IDC was associated with a lower mortality and should be standard of care in all patients with candidemia.

Abstract
Background An evidence-based preoperative bundle including chlorhexidine gluconate (CHG) bathing, screening for S. aureus nasal carriage and decolonizing carriers with mupirocin was the standard of care for patients having total joint arthroplasty (TJA) at a VA medical center. We aimed to assess patient compliance with mupirocin and CHG, and characterize patient perceptions of barriers and facilitators to compliance. Compliance with CHG Bathing & Mupirocin By Methicillin-resistant S. aureus (MRSA) or Methicillin-susceptible S. aureus (MSSA) Colonization Status ![]()
Methods The bundle for S. aureus colonized patients having TJA included nasal mupirocin ointment twice daily and daily CHG bathing for 5 days before surgery. The bundle for non-carriers included CHG bathing the day before and the morning of surgery. From 7/2018-10/2019, inpatients completed a 31-item survey following their TJA. Results 73 patients completed the survey (~29% of the TJA population). 17 patients (23%) carried S. aureus & 56 patients (77%) were non-carriers. Patients reported high compliance with home use of CHG for the full number of days directed (88% when prescribed for 2 days; 71% when prescribed for 5 days; overall 85% used as prescribed; Figure). 7 (10%) patients reported CHG side effects, including burning or itchy/dry skin. 99% of patients reported willingness to use the CHG before a future surgery. Compliance with home use of mupirocin was lower (53% used as prescribed). Reported side effects included stinging, itching or dryness (N=2, 12%), unpleasant taste (N=2, 12%) & runny or stuffy nose (N=3, 18%). 100% of patients reported willingness to use mupirocin before a future surgery. Barriers to patient compliance with the bundle included forgetfulness and difficulty bathing daily. Facilitators to patient compliance included high facility compliance with S. aureus screening (100% patients reported), patient education regarding CHG and mupirocin use (95% patients recalled), and access to prescribed medications (100% patients received). Most patients (93%) reported no financial burden for mupirocin and 95% of patients reported no financial burden for CHG. Conclusion Patients reported high willingness to use the prevention bundle, yet mupirocin compliance was sub-optimal. Replacing patient-applied home mupirocin with nurse-applied day-of-surgery decolonization should be assessed in order to facilitate increased compliance.

Abstract
PURPOSE To synthesize existing observational evidence to identify disparities in stage at breast cancer diagnosis between foreign- and native-born women. We hypothesized immigrant women would be less likely than natives to be diagnosed at a localized stage. METHODS Systematic searches for studies detailing stage at breast cancer diagnosis by birthplace in PubMed, Embase, and Web of Science yielded 11 relevant cohort studies from six countries. Odds ratios were pooled using random effects models. RESULTS Foreign-born women were 12% less likely to be diagnosed with breast cancer at a localized stage than natives (OR 0.88, 95% CI 0.82-0.95). A similar disadvantage was observed in immigrants from Asia, Eastern Europe, Latin America and the Caribbean, and developing or in transition nations; immigrants from developed countries experienced the least disparity. CONCLUSIONS This meta-analysis confirmed the presence of significant differences in breast cancer stage at diagnosis as per nativity. Across diverse immigrant groups and host countries, foreign-born women were significantly less likely to be diagnosed with localized breast cancer than native women; the magnitude of the disparity varied by region and economic condition of immigrants' birthplace.

Abstract
IMPORTANCE Health care-associated infections (HAIs) are preventable, harmful, and costly; however, few resources are dedicated to infection surveillance of nonsurgical procedures, particularly cardiovascular implantable electronic device (CIED) procedures. OBJECTIVE To develop a method that includes text mining of electronic clinical notes to reliably and efficiently measure HAIs for CIED procedures. DESIGN, SETTING, AND PARTICIPANTS In this multicenter, national cohort study using electronic medical record data for patients undergoing CIED procedures in Veterans Health Administration (VA) facilities for fiscal years (FYs) 2016 and 2017, an algorithm to flag cases with a true CIED-related infection based on structured (eg, microbiology orders, vital signs) and free text diagnostic and therapeutic data (eg, procedure notes, discharge summaries, microbiology results) was developed and validated. Procedure data were divided into development and validation data sets. Criterion validity (ie, positive predictive validity [PPV], sensitivity, and specificity) was assessed via criterion-standard manual medical record review. EXPOSURES CIED procedure. MAIN OUTCOMES AND MEASURES The concordance between medical record review and the study algorithm with respect to the presence or absence of a CIED infection. CIED infection in the algorithm included 90-day mortality, congestive heart failure and nonmetastatic tumor comorbidities, CIED or surgical site infection International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Clinical Modification (ICD-10-CM) diagnosis codes, antibiotic treatment of Staphylococci, a microbiology test of a cardiac specimen, and text documentation of infection in specific clinical notes (eg, cardiology, infectious diseases, inpatient discharge summaries). RESULTS The algorithm sample consisted of 19 212 CIED procedures; 15 077 patients (78.5%) were White individuals, 1487 (15.5%) were African American; 18 766 (97.7%) were men. The mean (SD) age in our sample was 71.8 (10.6) years. The infection detection threshold of predicted probability was set to greater than 0.10 and the algorithm flagged 276 of 9606 (2.9%) cases in the development data set (9606 procedures); PPV in this group was 41.4% (95% CI, 31.6%-51.8%). In the validation set (9606 procedures), at predicted probability 0.10 or more the algorithm PPV was 43.5% (95% CI, 37.1%-50.2%), and overall sensitivity and specificity were 94.4% (95% CI, 88.2%-97.9%) and 48.8% (95% CI, 42.6%-55.1%), respectively. CONCLUSIONS AND RELEVANCE The findings of this study suggest that the method of combining structured and text data in VA electronic medical records can be used to expand infection surveillance beyond traditional boundaries to include outpatient and procedural areas.

Thirty-day and 90-day mortality rates were significantly lower in the IDC group (18% vs 50%; P = .002; 23% vs 50%; P = .0022, respectively). A systematic literature review returned 216 reports, of which 13 studies including the present report fulfilled the inclusion criteria. Among the 13 studies with a total of 3582 patients, IDC was performed in 50% of patients. Overall mortality was 38.2% with a significant difference in favor of the IDC group (28.4% vs 47.6%), with a pooled relative risk of 0.41 (95% CI, 0.35-0.49). Ophthalmology referral, echocardiogram, and central line removal were performed more frequently among patients receiving IDC. CONCLUSIONS This study is the first systematic literature review and meta-analysis to evaluate the association between IDC and candidemia mortality. IDC was associated with significantly lower mortality and should be considered in all patients with candidemia.

Abstract
BACKGROUND Acquisition of pathogens into health care settings from prior room occupants has been documented. Hospital room privacy curtains are at high risk for pathogenic bacterial contamination. Antimicrobial impregnated curtains could be effective in reducing contamination. METHODS Rooms within an intensive care unit at The University of Iowa Hospitals and Clinics were randomized to 3 arms. The 2 intervention arms: (1) halamine antimicrobial curtains (BioSmart curtain [BSC]) and (2) halamine antimicrobial curtains sprayed twice weekly with a sodium hypochlorite-based disinfecting spray (BSC-pre and BSC-post) and a third control arm (standard curtain [SC]). Samples were collected twice weekly for 3 weeks to assess pathogenic bacterial contamination. RESULTS The likelihood of remaining uncontaminated was 38% for SC, 37% for BSC, and 60% for the BSC-pre group. Time to event (contamination) analysis found no statistically significant difference between pathogenic contamination between the SC, BSC, and BSC-pre groups (P value = .1921). There was a decrease in average colony count for BSC curtains compared with control, however, this difference was not statistically significant. Hypochlorite spray was found to transiently decontaminate curtains, but effects dissipated after 72 hours. CONCLUSIONS BSC did not show a significant reduction in pathogenic contamination compared with control. Antimicrobial curtains could have a role in reducing environmental contamination in the health care setting. Future studies should be done to determine the long-term effects of using antimicrobial curtains in health care.

Abstract
IMPORTANCE Staphylococcus aureus bacteremia (SAB) is common and associated with poor long-term outcomes. Previous studies have demonstrated an association between infectious diseases (ID) consultation and improved short-term (ie, within 90 days) outcomes for patients with SAB, but associations with long-term outcomes are unknown. OBJECTIVE To investigate the association of ID consultation with long-term (ie, 5 years) postdischarge outcomes among patients with SAB. DESIGN, SETTING, AND PARTICIPANTS This cohort study included all patients (N = 31 002) with a first episode of SAB who were discharged alive from 116 acute care units of the nationwide Veterans Health Administration where ID consultation was offered. Data were collected from January 2003 to December 2014, with follow-up through September 30, 2018. Data analysis was conducted from February to December 2019. EXPOSURES Infectious diseases consultation during the index hospital stay. MAIN OUTCOMES AND MEASURES The primary outcome was time to development of a composite event of all-cause mortality or recurrence of SAB within 5 years of discharge. As secondary outcomes, SAB recurrence and all-cause mortality with and without recurrence were analyzed while accounting for semicompeting risks. RESULTS The cohort included 31 002 patients (30 265 [97.6%] men; median [interquartile range] age at SAB onset, 64.0 [57.0-75.0] years). Among 31 002 patients, there were 18 794 (60.6%) deaths, 4772 (15.4%) SAB recurrences, and 20 414 (65.8%) composite events during 5 years of follow-up; 12 773 deaths (68.0%) and 2268 recurrences (47.5%) occurred more than 90 days after discharge. Approximately half of patients (15 360 [49.5%]) received ID consultation during the index hospital stay; ID consultation was associated with prolonged improvement in the composite outcome (adjusted hazard ratio at 5 years, 0.71; 95% CI, 0.68-0.74; P < .001). Infectious diseases consultation was also associated with improved outcomes when all-cause mortality without recurrence and SAB recurrence were analyzed separately (all-cause mortality without recurrence: adjusted hazard ratio at 5 years, 0.77; 95% CI, 0.74-0.81; P < .001; SAB recurrence: adjusted hazard ratio at 5 years, 0.68; 95% CI, 0.64-0.72; P < .001). CONCLUSIONS AND RELEVANCE Having an ID consultation during the index hospital stay among patients with SAB was associated with improved postdischarge outcomes for at least 5 years, suggesting that contributions of ID specialists to management during acute infection may have a substantial influence on long-term outcomes. Further investigations of the association of ID consultation with outcomes after S aureus should include long-term follow-up.

Abstract
Background Antimicrobial prophylaxis is an evidence-proven strategy for reducing procedure-related infections; however, measuring this key quality metric typically requires manual review, due to the way antimicrobial prophylaxis is documented in the electronic medical record (EMR). Our objective was to electronically measure compliance with antimicrobial prophylaxis using both structured and unstructured data from the Veterans Health Administration (VA) EMR. We developed this methodology for cardiac device implantation procedures. Methods With clinician input and review of clinical guidelines, we developed a list of antimicrobial names recommended for the prevention of cardiac device infection. We trained the algorithm using existing fiscal year (FY) 2008–15 data from the VA Clinical Assessment Reporting and Tracking-Electrophysiology (CART-EP), which contains manually determined information about antimicrobial prophylaxis. We merged CART-EP data with EMR data and programmed statistical software to flag an antimicrobial orders or drug fills from structured data fields in the EMR and hits on text string searches of antimicrobial names documented in clinician’s notes. We iteratively tested combinations of these data elements to optimize an algorithm to accurately classify antimicrobial use. The final algorithm was validated in a national cohort of VA cardiac device procedures from FY2016–2017. Discordant cases underwent expert manual review to identify reasons for algorithm misclassification. Results The CART-EP dataset included 2102 procedures at 38 VA facilities with manually identified antimicrobial prophylaxis in 2056 cases (97.8%). The final algorithm combining structured EMR fields and text note search results correctly classified 2048 of the CART-EP cases (97.4%). In the validation sample, the algorithm measured compliance with antimicrobial prophylaxis in 16,606 of 18,903 cardiac device procedures (87.8%). Misclassification was due to EMR documentation issues, such as antimicrobial prophylaxis documented only in hand-written clinician notes in a format that cannot be electronically searched. Conclusions We developed a methodology with high accuracy to measure guideline concordant use of antimicrobial prophylaxis before cardiac device procedures using data fields present in modern EMRs. This method can replace manual review in quality measurement in the VA and other healthcare systems with EMRs; further, this method could be adapted to measure compliance in other procedural areas where antimicrobial prophylaxis is recommended.

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
OBJECTIVE We performed a systematic review of the literature and meta-analysis of the infectious complications of hysterectomy, comparing robotic-assisted hysterectomy to conventional laparoscopic-assisted hysterectomy. METHODS We searched PubMed, CINAHL, CDSR, and EMBASE through July 2018 for studies evaluating robotic-assisted hysterectomy, laparoscopic-assisted hysterectomy, and infectious complications. We employed random-effect models to obtain pooled OR estimates. Heterogeneity was evaluated with I2 estimation and the Cochran Q statistic. Pooled ORs were calculated separately based on the reason for hysterectomy (eg, benign uterine diseases, endometrial cancer, and cervical cancer). RESULTS Fifty studies were included in the final review for the meta-analysis with 176 016 patients undergoing hysterectomy. There was no statistically significant difference in the number of infectious complication events between robotic-assisted hysterectomy and laparoscopic-assisted hysterectomy (pooled OR 0.97; 95 % CI 0.74 to 1.28). When we performed a stratified analysis, similar results were found with no statistically significant difference in infectious complications comparing robotic-assisted hysterectomy to laparoscopic-assisted hysterectomy among patients with benign uterine disease (pooled OR 1.10; 95 % CI 0.70 to 1.73), endometrial cancer (pooled OR 0.97; 95 % CI 0.55 to 1.73), or cervical cancer (pooled OR 1.09; 95 % CI 0.60 to 1.97). CONCLUSION In our meta-analysis the rate of infectious complications associated with robotic-assisted hysterectomy was no different than that associated with conventional laparoscopic-assisted hysterectomy.

Abstract
PURPOSE Our objective was to systematically review and meta-analyze studies that assessed the association between gestational vitamin D levels and risk of multiple sclerosis (MS) in offspring. METHODS Embase and Pubmed databases were searched from inception to May 2018. Original, observational studies that investigated both clinically defined MS (in offspring) and vitamin D levels in utero or shortly after birth were included. Two reviewers independently abstracted data and assessed the quality of studies using the Newcastle-Ottawa Quality Assessment Scale. Summary effect estimates and 95% confidence intervals were calculated with random effects models using inverse variance weighting. Determinants of heterogeneity were evaluated. RESULTS Four case-control studies of moderate to low risk of bias were included. Summary effect estimates of the effect of higher levels of gestational vitamin D on risk of offspring MS demonstrated a significant protective effect in random effects (OR: 0.63, 95% CI: 0.47, 0.84) models and in a stratified analysis based on study quality. Factors identified as determinants of heterogeneity were the definitions of vitamin D deficiency, the characteristics of study participants, and the quality of the study. CONCLUSIONS Sufficient levels of vitamin D during pregnancy may be protective against offspring's development of multiple sclerosis later in life.

Abstract
IMPORTANCE An understanding of the incidence and outcomes of Clostridium difficile infection (CDI) in the United States can inform investments in prevention and treatment interventions. OBJECTIVE To quantify the incidence of CDI and its associated hospital length of stay (LOS) in the United States using a systematic literature review and meta-analysis. DATA SOURCES MEDLINE via Ovid, Cochrane Library Databases via Wiley, Cumulative Index of Nursing and Allied Health Complete via EBSCO Information Services, Scopus, and Web of Science were searched for studies published in the United States between 2000 and 2019 that evaluated CDI and its associated LOS. STUDY SELECTION Incidence data were collected only from multicenter studies that had at least 5 sites. The LOS studies were included only if they assessed postinfection LOS or used methods accounting for time to infection using a multistate model or compared propensity score-matched patients with CDI with control patients without CDI. Long-term-care facility studies were excluded. Of the 119 full-text articles, 86 studies (72.3%) met the selection criteria. DATA EXTRACTION AND SYNTHESIS Two independent reviewers performed the data abstraction and quality assessment. Incidence data were pooled only when the denominators used the same units (eg, patient-days). These data were pooled by summing the number of hospital-onset CDI incident cases and the denominators across studies. Random-effects models were used to obtain pooled mean differences. Heterogeneity was assessed using the I2 value. Data analysis was performed in February 2019. MAIN OUTCOMES AND MEASURES Incidence of CDI and CDI-associated hospital LOS in the United States. RESULTS When the 13 studies that evaluated incidence data in patient-days due to hospital-onset CDI were pooled, the CDI incidence rate was 8.3 cases per 10 000 patient-days. Among propensity score-matched studies (16 of 20 studies), the CDI-associated mean difference in LOS (in days) between patients with and without CDI varied from 3.0 days (95% CI, 1.44-4.63 days) to 21.6 days (95% CI, 19.29-23.90 days). CONCLUSIONS AND RELEVANCE Pooled estimates from currently available literature suggest that CDI is associated with a large burden on the health care system. However, these estimates should be interpreted with caution because higher-quality studies should be completed to guide future evaluations of CDI prevention and treatment interventions.

Abstract
Background Treatment of rheumatoid arthritis (RA) often involves immune-suppressive therapies. Concern for recurrent prosthetic joint infection (PJI) in RA patients might be high and could reduce use of joint implantation in these patients. We aimed to evaluate the risk of recurrence of PJI in RA patients compared with osteoarthritis (OA) patients by utilizing a large health care system. Methods We conducted a retrospective cohort study of all patients admitted for a Staphylococcus aureus PJI who underwent debridement, antibiotics, and implant retention (DAIR) or 2-stage exchange (2SE) between 2003 and 2010 at 86 Veterans Affairs Medical Centers. Both RA patients and the comparison group of osteoarthritis (OA) patients were identified using International Classification of Diseases, Ninth Revision, codes. All index PJI and recurrent positive cultures for S. aureus during 2 years of follow-up were validated by manual chart review. A Cox proportional hazards regression model was used to compare the time to recurrent PJI for RA vs OA. Results In our final cohort of 374 veterans who had either DAIR or 2SE surgery for their index S. aureus PJI, 11.2% had RA (n = 42). The majority of the cohort was male (97.3%), and 223 (59.6%) had a methicillin-susceptible S. aureus PJI. RA patients had a similar risk of failure compared with OA patients, after adjusting for covariates (hazard ratio, 0.81; 95% confidence interval, 0.48–1.37). Conclusions Prior diagnosis of RA does not increase the risk of recurrent S. aureus PJI. Further studies are needed to evaluate the effect of different RA therapies on outcomes of episodes of PJI.

Abstract
Background In order to target future randomized controlled trials (RCT) of treatment of methicillin-resistant S aureus bloodstream infections (MRSA BSI), it will be important to understand the drivers of antibiotic selection. We aimed to determine factors associated with switching from vancomycin to inpatient linezolid administration during the management of MRSA BSI. Methods This retrospective cohort included all patients admitted to Veteran Affairs hospitals from 2007 to 2014 and had received vancomycin for MRSA BSI. Patients were considered to have switched to linezolid from vancomycin if they received at least 2 consecutive days of inpatient treatment and were not on concurrent vancomycin treatment. Cox proportional hazards models were used to identify factors that were associated with switch within 14 days and 30 days. Median with interquartile range (IQR), hazard ratio (HR) and 95% confidence intervals were reported. Results Among 7289 patients diagnosed with MRSA BSI during their index admission, 474 (6.5%) switched to linezolid during the admission. The median inpatient duration of vancomycin treatment among all patients was 13 days (IQR: 5–34) and among patients who switched was 16 days (IQR: 6–52). The median inpatient duration of linezolid treatment was 5 days (IQR: 1–13 days). Patients who switched to linezolid were more likely to have a MRSA isolate with MIC >=2 µg/mL (6.8% vs. 4.9%), diagnosis of respiratory tract infection (36.7% vs. 32.9%), or be obese (16.5% vs. 13.6%) than those who continued on vancomycin (P < 0.10). In risk-adjustment models, presence of a respiratory tract infection diagnosis was associated with greater likelihood of being switched to linezolid within 14- and 30-days (HR=1.29, 95% CI 1.01–1.64; HR=1.32, 95% CI 1.06–1.65). Conclusion Less than 10% of patients initially treated with vancomycin for MRSA BSI were switched to linezolid in this real-world study. A diagnosis of respiratory tract infection was a major determinant of switching to linezolid. It is important to identify potential subsets of MRSA BSI patients so that future comparative effectiveness RCTs can be targeted to indications with clinical equipoise in real-world practice settings.

Abstract
Abstract
Background
Performing urinalyses and urine cultures in asymptomatic patients is one of the most common reasons for inappropriate antibiotic use. However, de-implementing this practice has been difficult, especially for clinical scenarios deemed to be high risk for infectious complications, such as among patients with delirium or those undergoing orthopedic implant surgery.
Methods
Using the dual-process theory framework “Developing De-Implementation Strategies Based on Un-Learning and Substitution,” an educational intervention citing new IDSA guidelines and providing a pneumonic “ABCs of ASB” was created and delivered didactically to providers. The goal was to increase performance of evidence-based prevention actions in place of low-value urine screening and treating of asymptomatic patients. Clinical providers and staff (MD, RN, APRN, trainees) in 3 different levels of care (acute inpatient, long-term, and outpatient) were included. A web-based anonymous and confidential pre- and post-question format was delivered to assess influence on provider behavior.
Results
Responses from a range of 250–279 unique providers were collected. For scenario #1 (patient with delirium and a positive urine culture and no other infectious symptoms), the option to give antibiotics was reduced by 45% pre to 4% post, Chi-square P < 0.01). For scenario #2 (patient having a knee replacement and positive preoperative urine culture, no other symptoms) the option to give antibiotics was reduced by the same magnitude (~50%) but a lower absolute number (67% pre and 33% post, chi-square P < 0.01). Changes in predicted behavior were similar across levels of care.
Conclusion
Substituting evidence-based practices in place of low-value practices is an appealing framework for influencing provider behavior. Our work demonstrates that education can successfully reduce the intention to use antibiotics for asymptomatic patients with positive urine cultures.

Abstract
OBJECTIVE With the current public health burden of sexually transmitted infections, it is important to identify factors affecting condom use. The association between marijuana use and condom use is especially important because of the increasing number of U.S. states legalizing marijuana; however, relevant research findings are mixed. The goal of this study was to perform a meta-analysis assessing the relationship between marijuana and condom use at instances of sexual intercourse. METHOD A systematic search of four databases was performed. Data were extracted and pooled estimates were calculated using random-effects models with inverse variance weighting. Heterogeneity was evaluated using the Cochran Q chi-square test. RESULTS Eleven studies were included. There was a statistically significant relationship between marijuana and condom use in the overall pooled analysis (odds ratio [OR] = 0.71, 95% CI [0.56, 0.89]), and studies were homogeneous, I2 = 12%, χ2(10) = 11.37, p = .33. Stratified analyses showed that although the pooled OR was not significant for adults (OR = 0.92, 95% CI [0.64, 1.33]), there was a significant relationship between condom use and marijuana use for adolescents (OR = 0.62, 95% CI [0.47, 0.82]). CONCLUSIONS This meta-analysis found that the odds of condom use were lower for those who used marijuana around the time of intercourse than for those who did not, with this effect only significant for adolescents in a subgroup analysis. As the adolescent populations in this analysis were not representative of a general population of adolescents, future research should focus not only on those considered high risk.

Abstract
Abstract
The 2014–2016 Ebola epidemic in West Africa provided an opportunity to improve our response to highly infectious diseases. We performed a systematic literature review in PubMed, Cochrane Library, CINAHL, EMBASE, and Web of Science of research articles that evaluated benefits and challenges of hospital Ebola preparation in developed countries. We excluded studies performed in non-developed countries, and those limited to primary care settings, the public health sector, and pediatric populations. Thirty-five articles were included. Preparedness activities were beneficial for identifying gaps in hospital readiness. Training improved health-care workers’ (HCW) infection control practices and personal protective equipment (PPE) use. The biggest challenge was related to PPE, followed by problems with hospital infrastructure and resources. HCWs feared managing Ebola patients, affecting their willingness to care for them. Standardizing protocols, PPE types, and frequency of training and providing financial support will improve future preparedness. It is unclear whether preparations resulted in sustained improvements.

Abstract
OBJECTIVE An important extra-articular manifestation of rheumatoid arthritis (RA) is interstitial lung disease (ILD). The relationship between the usual interstitial pneumonia (UIP) pattern and mortality in patients with RA is unclear. The purpose of this study was to complete a systematic literature review and meta-analysis on the association between RA-ILD pattern and mortality risk. METHODS We performed a systematic literature review through December 12, 2018. Study characteristics, unadjusted and adjusted relative risks (RR) of mortality for ILD pattern were extracted from the identified studies and quality assessments were performed. RR for mortality (RA-UIP vs. other RA-ILD) was pooled using inverse variance weighting and random effects models. RESULTS Ten retrospective cohort studies met our eligibility criteria. A total of 1256 RA-ILD patients were included with 484 total deaths. Meta-analysis yielded a pooled RR of 1.66 (95% confidence interval1.07 to 2.56) for death among those with UIP RA-ILD compared with other patterns. In sub-group analysis when pooling studies comparing UIP to NSIP pattern of RA-ILD, the RR was 2.39 (95% CI 0.86-6.68). CONCLUSION Through a systematic literature review and meta-analysis, we found UIP pattern to be associated with a higher mortality risk in RA-ILD compared to other patterns of RA-ILD although more recent studies emphasize the importance of pulmonary physiology and the extent of lung involvement as significant predictors of mortality rather than the pattern of RA-ILD. Recognizing the small number of studies satisfying eligibility and inconsistent accounting for confounders, further study of mortality risk in RA-ILD is needed with standardized assessment of various RA, ILD, and patient-related factors.

Abstract
BACKGROUND Recent studies have shown that using minimally invasive surgical techniques (conventional laparoscopy or robotic) for prostatectomy is associated with lower perioperative complication rates compared with open radical retropubic prostatectomy. However, differences in infectious complications between these minimally invasive approaches are not well characterized. To study this further, we performed a systematic review of the literature and meta-analysis of the infectious complications of prostatectomy, comparing robotic prostatectomy (RP) with conventional laparoscopic prostatectomy (LP). METHODS We searched PubMed, CINAHL, CDSR, and EMBASE through September 2018 for studies evaluating minimally invasive prostatectomy and infectious complications. We employed random-effect models to obtain pooled odds ratio (pOR) estimates. Heterogeneity was evaluated with I2 estimation and the Cochran Q statistic. pORs were calculated separately based on the indication for prostatectomy. RESULTS Fifteen studies were included in the final review for the meta-analysis with 14,121 patients undergoing minimally invasive prostatectomy. There was no statistically significant difference in the number of infectious complication events between RP and LP (pOR 0.94; 95% CI 0.50, 1.76). When we performed a stratified analysis, similar results were found with no statistically significant difference in infectious complications comparing RP with LP among patients with prostate cancer (pOR 0.73; 95% CI 0.43, 1.24). We observed that infectious complications were nearly threefold higher with the robotic approach in earlier studies (published between 2007 and 2012, pOR 2.81; 95% CI 1.07, 7.39), but no significant difference was found in later studies (between 2013 and 2018, pOR 0.80, 95% CI 0.40, 1.57). CONCLUSIONS The rate of infectious complications associated with RP was no different than that associated with conventional LP.

Abstract
Diabetes mellitus (DM) serves as an important prognostic indicator in patients with cardiac-related illness. Our objective is to compare survival and neurological outcomes among diabetic and non-diabetic patients who were admitted to the hospital after an out-of-hospital cardiac arrest (OHCA). We searched MEDLINE and EMBASE for relevant articles from database inception to July 2018 without any language restriction. Studies were included if they evaluated patients who presented with OHCA, included mortality and neurological outcome data separately for DM patients and Non-DM patients and reported crude data, odds ratio (OR), relative risk (RR) or hazard ratio (HR). Two investigators independently reviewed the retrieved citations and assessed eligibility. The quality of included studies was evaluated using Newcastle-Ottawa quality assessment scale for cohort studies. Random-effect models using the generic variance method were used to create pooled odds ratios (OR) and 95% confidence intervals (CI). Heterogeneity was assessed using the I2 value. Survival and neurological outcomes (using modified rankin scale and cerebral performance category scale) after OHCA in hospitalized patients with DM compared with patients without DM. Out of 57 studies identified, six cohort studies met the inclusion criteria. In an analysis of unadjusted data, patients with DM had lower odds of survival, pooled OR 0.64; 95% CI, 0.52-0.78, [I2 = 90%]. When adjusted ORs were pooled, the association between DM and survival after OHCA was still significantly reduced, pooled OR 0.78, 95% CI, 0.68-0.89 [I2 = 55%]. Unadjusted pooled OR revealed poor neurological outcomes in patients with DM, pooled OR 0.55, 95% CI, 0.38-0.80 [I2 = 90%]. The result demonstrates significant poor outcomes of in-hospital survival and neurological outcomes among DM patients after OHCA.

Abstract
BACKGROUND Antimicrobial resistance has become an urgent global health priority. Basic hygiene practices and cleaning and disinfection of the hospital environment are key in preventing pathogen cross-transmission. AIM To our knowledge no studies have assessed the worldwide differences in cleaning and disinfection practices in healthcare facilities. The electronic survey described here was developed in order to evaluate differences in healthcare facility cleaning practices around the world. METHODS The International Society of Antimicrobial Chemotherapy (ISAC, formerly ISC), Infection Prevention and Control work group developed a survey with 30 multiple-choice questions. The questions were designed to assess the current cleaning practices in healthcare settings around the world. FINDINGS A total of 110 healthcare professionals, representing 23 countries, participated in the online survey. In 96% of the facilities a written cleaning policy was present. Training of cleaning staff occurred in 70% of the facilities at the start of employment. Cleaning practices and monitoring of these practices varied. CONCLUSIONS The survey enabled assessment and recognition of widely differing global practices in approaches to environmental cleaning and disinfection. Development of guideline recommendations for cleaning and disinfection could improve practices and set minimum standards worldwide.

BACKGROUND Previous evidence supports that vitamin A decreases the risk of several types of cancer. However, the association between vitamin A and liver cancer is inconclusive. AIM This systematic review and meta-analysis summarizes the existing literature, discussing the association between vitamin A intake, serum vitamin A, and liver cancer in adult populations. METHODS A systematic literature review was performed by searching the EMBASE, PubMed, Scopus and International Pharmaceutical Abstract databases using terms related to vitamin A (e.g. retinol, α-carotene, β-carotene, and β-cryptoxanthin) and hepatic cancer without applying any time restriction. A meta-analysis was performed using random effect models. RESULTS The meta-analysis of five studies showed no association between serum retinol and liver cancer (pooled risk ratio = 1.90 (0.40-9.02); n = 5 studies, I2 = 92%). In addition, the systematic review of studies from 1955 to July 2017 found studies that indicated no association between the intake and serum level of α-carotene ( n = 2) and β-cryptoxanthin ( n = 1) and the risk of liver cancer. Further, the associations between retinol intake ( n = 3), β-carotene intake ( n = 3), or serum β-carotene ( n = 3) and liver cancer were inconclusive. CONCLUSIONS Current information on the association between vitamin A intake and liver cancer or serum vitamin A and liver cancer are limited. Most studies demonstrated no association between dietary vitamin A and the risk of liver cancer. However, the finding was based on a small number of studies with potential publication bias. Therefore, large observational studies should be conducted to confirm these associations.

Abstract
Older adults are at increased risk for septic arthritis and prosthetic joint infections (PJI), owing at least in part to comorbid conditions and frailty. An increasing number of older adults undergo total joint arthroplasty to improve their quality of life. Infections in older adults differ from younger populations by the causative organisms, a great proportion of which are Staphylococcal infections. Targeting important modifiable and nonmodifiable risk factors may prevent or reduce the burden of joint infections in older adults. This review summarizes the epidemiology, pathogenesis, clinical manifestations, diagnosis, management, and prevention of septic arthritis and PJI in older adults.

Abstract
Background Carbapenem-resistant Enterobacteriaceae (CRE) pose an urgent public health threat in the United States. An important step in planning and monitoring a national response to CRE is understanding its epidemiology and associated outcomes. We conducted a systematic literature review of studies that investigated incidence and outcomes of CRE infection in the US. Methods We performed searches in MEDLINE via Ovid, CDSR, DARE, CENTRAL, NHS EED, Scopus, and Web of Science for articles published from 1/1/2000 to 2/1/2016 about the incidence and outcomes of CRE at US sites. Results Five studies evaluated incidence, but many used differing definitions for cases. Across the entire US population, the reported incidence of CRE was 0.3–2.93 infections per 100,000 person-years. Infection rates were highest in long-term acute-care (LTAC) hospitals. There was insufficient data to assess trends in infection rates over time. Four studies evaluated outcomes. Mortality was higher in CRE patients in some but not all studies. Conclusion While the incidence of CRE infections in the United States remains low on a national level, the incidence is highest in LTACs. Studies assessing outcomes in CRE-infected patients are limited in number, small in size, and have reached conflicting results. Future research should measure a variety of clinical outcomes and adequately adjust for confounders to better assess the full burden of CRE.
