Electronic hand hygiene monitoring systems: Not worth the costs.

Electronic hand hygiene monitoring systems allow the collection of large volumes of data. However, significant resources are required to validate and maintain these systems. Additionally, data are lacking on the correlation with clinically important outcomes. Direct observation of hand hygiene remains the gold standard for monitoring hand hygiene compliance.

The coronavirus disease 2019 (COVID-19) delta wave: Refocusing effort and remaining resilient in the face of evolving infection prevention and antimicrobial stewardship challenges.

Challenges for infection prevention and antimicrobial stewardship programs have arisen with the fourth wave of the coronavirus disease 2019 (COVID-19) pandemic, fueled by the delta variant. These challenges include breakthrough infections in vaccinated individuals, decisions to re-escalate infection prevention measures, critical medication shortages, and provider burnout. Various strategies are needed to meet these challenges.

Chasing the rate: An interrupted time series analysis of interventions targeting reported hospital onset Clostridioides difficile, 2013-2018.

OBJECTIVE: To assess the impact of major interventions targeting infection control and diagnostic stewardship in efforts to decrease Clostridioides difficile hospital onset rates over a 6-year period. DESIGN: Interrupted time series. SETTING: The study was conducted in an 865-bed academic medical center. METHODS: Monthly hospital-onset C. difficile infection (HO-CDI) rates from January 2013 through January 2019 were analyzed around 5 major interventions: (1) a 2-step cleaning process in which an initial quaternary ammonium product was followed with 10% bleach for daily and terminal cleaning of rooms of patients who have tested positive for C. difficile (February 2014), (2) UV-C device for all terminal cleaning of rooms of C. difficile patients (August 2015), (3) "contact plus" isolation precautions (June 2016), (4) sporicidal peroxyacetic acid and hydrogen peroxide cleaning in all patient areas (June 2017), (5) electronic medical record (EMR) decision support tool to facilitate appropriate C. difficile test ordering (March 2018). RESULTS: Environmental cleaning interventions and enhanced "contact plus" isolation did not impact HO-CDI rates. Diagnostic stewardship via EMR decision support decreased the HO-CDI rate by 6.7 per 10,000 patient days (P = .0079). When adjusting rates for test volume, the EMR decision support significance was reduced to a difference of 5.1 case reductions per 10,000 patient days (P = .0470). CONCLUSION: Multiple aggressively implemented infection control interventions targeting CDI demonstrated a disappointing impact on endemic CDI rates over 6 years. This study adds to existing data that outside of an outbreak situation, traditional infection control guidance for CDI prevention has little impact on endemic rates.

A comparison of the accuracy of two electronic hand hygiene monitoring systems.

Interest in electronic hand hygiene monitoring systems (EHHMSs) is now widespread throughout the infection control community. We tested 2 types of EHHMS for accuracy. The type B EHHMS captured more HH events with superior accuracy. Hospitals considering an EHHMS should assess the technology's ability to accurately capture HH performance in the clinical workflow.

The impact of formulary restriction on the relative consumption of carbapenems in intensive care units at an academic medical center.

Antipseudomonal carbapenems are an important target for antimicrobial stewardship programs. We evaluated the impact of formulary restriction and preauthorization on relative carbapenem use for medical and surgical intensive care units at a large, urban academic medical center using interrupted time-series analysis.
