Impact of clinician feedback reports on antibiotic use in children hospitalized with community-acquired pneumonia.

Background: Feedback reports summarizing clinician performance are effective tools for improving antibiotic use in the ambulatory setting, but the effectiveness of feedback reports in the hospital setting is unknown.

Methods: Quasi-experimental study conducted between December 2021 and November 2023 within a pediatric health system measuring the impact of clinician feedback reports delivered by email and reviewed in a monthly meeting on appropriate antibiotic use in children hospitalized with community-acquired pneumonia (CAP). We used an interrupted time series analysis (ITSA) to estimate the immediate change and change over time in the proportion of CAP encounters adherent to validated metrics of antibiotic choice and duration, then used Poisson regression to estimate intervention effect as a rate ratio (RR).

Postoperative outcomes after receipt of ertapenem antimicrobial prophylaxis for colon surgery: a multicenter retrospective cohort study.

Objective: To evaluate postoperative outcomes among patients undergoing colon surgery who receive perioperative prophylaxis with ertapenem compared to other antibiotic regimens.

Design And Setting: Multicenter retrospective cohort study among adults undergoing colon surgery in seven hospitals across three health systems from 1/1/2010 to 9/1/2015.

Methods: Generalized linear mixed logistic regression models were applied to assess differential odds of select outcomes among patients who received perioperative prophylaxis with ertapenem compared to other regimens.

Gut microbiome correlates of recurrent urinary tract infection: a longitudinal, multi-center study.

Background: Urinary tract infections (UTI) affect approximately 250 million people annually worldwide. Patients often experience a cycle of antimicrobial treatment and recurrent UTI (rUTI) that is thought to be facilitated by a gut reservoir of uropathogenic (UPEC).

Methods: 125 patients with UTI caused by an antibiotic-resistant organism (ARO) were enrolled from July 2016 to May 2019 in a longitudinal, multi-center cohort study.

Impact of deceased organ donor marijuana use on donor culture positivity and solid organ transplant recipient outcomes.

With the increasing prevalence of marijuana use in the US, many deceased organ donors have a history of marijuana use, raising concerns about infectious risks to transplant recipients. We performed a multicenter retrospective cohort study in which exposed donors were those with recent marijuana use (in the prior 12 months) and unexposed donors were those with no recent marijuana use. Primary outcomes included the following: (1) positive donor cultures for bacteria or fungi, (2) recipient infection due to bacteria or fungi within 3 months posttransplant, and (3) recipient graft failure or death within 12 months posttransplant.

Risk Factors for Recurrence of Community-Onset Urinary Tract Infections Caused by Extended-Spectrum Cephalosporin-Resistant Enterobacterales.

Background: Extended-spectrum cephalosporin-resistant Enterobacterales (ESCrE) are an increasingly important cause of community-onset urinary tract infections (UTIs), including recurrent infections. We evaluated risk factors for recurrence among patients with community-onset ESCrE UTI.

Methods: This retrospective cohort study included adults with community-onset ESCrE UTI in the Duke University Health System from April 2018 through December 2021.
