Background: Hospital-onset bacteraemia and fungaemia (HOB) is being explored as a surveillance and quality metric. The objectives of the current study were to determine sources and preventability of HOB in hospitalised patients in the USA and to identify factors associated with perceived preventability.
Methods: We conducted a cross-sectional study of HOB events at 10 academic and three community hospitals using structured chart review.
Background: Rifampin is recommended as adjunctive therapy for patients with a 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 PJI using Veterans Health Administration (VHA) data.
Methods: We conducted a retrospective cohort study of patients with PJI managed with DAIR between 2003 and 2019 in VHA hospitals.
Objective: To externally validate various prognostic models and scoring rules for predicting short term mortality in patients admitted to hospital for covid-19.
Design: Two stage individual participant data meta-analysis.
Setting: Secondary and tertiary care.
Background: We conducted a meta-analysis of observational epidemiological studies to evaluate the association between periconceptional use of vitamin A and the risk of giving birth to a child with nonsyndromic orofacial clefts (NSOFCs).
Methods: We carried out a systematic literature search of Embase, PubMed, Web of Science, Google Scholar, and OpenGrey from inception to June 30, 2021. Two reviewers independently evaluated the studies that met the inclusion criteria and filled out an abstraction form for each study.
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.
Introduction: Approximately 38% of haemodialysis patients carry in their noses, and carriers have a nearly four-fold increased risk of 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.
View Article and Find Full Text PDFPurpose: This review aims to critically evaluate the efficacy of web or mobile-based (WMB) interventions impacting emotional symptoms in patients with advanced cancer.
Method: Articles published from 1991 to 2019 were identified using PubMed, PsycINFO, CINAHL, and Scopus. Only interventions involving adults with advanced cancer using a WMB intervention to manage emotional symptoms were included.
Background: In this pilot trial, we evaluated whether audit-and-feedback was a feasible strategy to improve antimicrobial prescribing in emergency departments (EDs).
Methods: We evaluated an audit-and-feedback intervention using a quasi-experimental interrupted time-series design at 2 intervention and 2 matched-control EDs; there was a 12-month baseline, 1-month implementation, and 11-month intervention period. At intervention sites, clinicians received (1) a single, one-on-one education about antimicrobial prescribing for common infections and (2) individualized feedback on total and condition-specific (uncomplicated acute respiratory infection [ARI]) antimicrobial use with peer-to-peer comparisons at baseline and every quarter.
Background: The Centers for Medicare & Medicaid Services (CMS) use hospital readmissions as a performance metric to incentivize hospital care for acute conditions including pneumonia. However, there are limitations to using readmission alone as a hospital performance metric.
Objective: To characterize 30-day risk-standardized home time (RSHT), a novel patient-centered post-discharge performance metric for acute pneumonia hospitalizations in Medicare patients, and compare hospital rankings based on this metric with mortality and readmissions.
Background: Symptom management is a critical aspect of comprehensive palliative care for people with advanced cancer. Web and mobile-based applications are promising e-Health modalities that can facilitate timely access to symptom management interventions for this population.
Aim: To evaluate the efficacy of web and mobile-based symptom management interventions in alleviating physical symptom burden in people with advanced cancer.
Objective: To develop a fully automated algorithm using data from the Veterans' Affairs (VA) electrical medical record (EMR) to identify deep-incisional surgical site infections (SSIs) after cardiac surgeries and total joint arthroplasties (TJAs) to be used for research studies.
Design: Retrospective cohort study.
Setting: This study was conducted in 11 VA hospitals.
Background: Candidemia is one of the most common causes of nosocomial bloodstream infections, but the impacts of factors affecting its incidence have not been evaluated.
Methods: We analyzed a retrospective cohort of all candidemia patients at 130 acute care hospitals in the Veterans Health Administration (VHA) system from January 2000 through December 2017. Cases were classified as hospital-onset (HO) and non-hospital-onset (NHO).
Objectives: Carbapenems are an important target for antimicrobial stewardship (AS) efforts. In this study, we sought to compare different hospital-based strategies for improving carbapenem use.
Methods: We analysed a cohort of all patients hospitalized at Veterans Health Administration (VHA) acute care hospitals during 2016 and a mandatory survey that characterized each hospital's carbapenem-specific AS strategy into one of three types: no strategy (NS), prospective audit and feedback (PAF) or restrictive policies (RP).

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.
Objective: Assessments of antibiotic prescribing in ambulatory care have largely focused on viral acute respiratory infections (ARIs). It is unclear whether antibiotic prescribing for bacterial ARIs should also be a target for antibiotic stewardship efforts. In this study, we evaluated antibiotic prescribing for viral and potentially bacterial ARIs in patients seen at emergency departments (EDs) and urgent care centers (UCCs).

We evaluated the relationship between local MRSA prevalence rates and antibiotic use across 122 VHA hospitals in 2016. Higher hospital-level MRSA prevalence was associated with significantly higher rates of antibiotic use, even after adjusting for case mix and stewardship strategies. Benchmarking anti-MRSA antibiotic use may need to adjust for MRSA prevalence.
View Article and Find Full Text PDFBackground: Many US hospitals lack infectious disease (ID) specialists, which may hinder antibiotic stewardship efforts. We sought to compare patient-level antibiotic exposure at Veterans Health Administration (VHA) hospitals with and without an on-site ID specialist, defined as an ID physician and/or ID pharmacist.
Methods: This retrospective VHA cohort included all acute-care patient admissions during 2016.
Excess length of stay (LOS) is an important outcome when assessing the burden of nosocomial infection, but it can be subject to survival bias. We aimed to estimate the change in LOS attributable to hospital-onset (HO) / spp. bacteremia using multistate models to circumvent survival bias.

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.
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.

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.
View Article and Find Full Text PDFBackground: Despite increasing awareness of harms, fluoroquinolones are still frequently prescribed to inpatients and at hospital discharge. Our goal was to describe fluoroquinolone prescribing at hospital discharge across the Veterans Health Administration (VHA) and to contrast the volume and appropriateness of fluoroquinolone prescribing across 3 antimicrobial stewardship strategy types.
Methods: We analyzed a retrospective cohort of patients hospitalized at 122 VHA acute-care hospitals during 2014-2016.
Purpose: To evaluate the performance of an automated computerized ICU severity scoring derived from the APACHE III.
Materials And Methods: Within a retrospective cohort of patients admitted to Veterans Health Administration ICUs between 2009 and 2015, we created an automated illness severity score(modified APACHE or mAPACHE), that we extracted from the electronic health records, using the same scoring as the APACHE III excluding the Glasgow Coma Scale, urine output, arterial blood gas components of APACHE III. We assessed the mAPACHE discrimination by using the area under the curve(AUC), and calibration by using the Hosmer-Lemeshow test and calculating the difference between observed and expected mortality across equal-sized risk deciles for death.
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.
