To determine healthcare-associated infection (HAI) prevalence in nine Jacksonville, FL hospitals, evaluate the performance of proxy indicators for HAIs, and refine methodology in preparation for a multi-state survey.
Point prevalence survey.
Acute care inpatients of any age.
HAIs were defined using National Healthcare Safety Network criteria. In each facility a trained Primary Team (PT) of infection prevention (IP) staff performed the survey on 1 day, reviewing records and collecting data on a random sample of inpatients. PTs assessed patients with ≥1 proxy indicator (abnormal white blood cell count, abnormal temperature, or antimicrobial therapy) for the presence of HAIs. An external IP expert team collected data from a subset of patient records reviewed by PTs to assess proxy indicator performance and PT data collection.
Of 851 patients surveyed by PTs, 51 had ≥1 HAI (6.0%, 95% confidence interval 4.5–7.7%). Surgical site infections (n=18), urinary tract infections (n=9), pneumonia (n=9), and bloodstream infections (n=8) accounted for 75.8% of 58 HAIs detected by PTs. Staphylococcus aureus was the most common pathogen, causing 9 HAIs (15.5%). Antimicrobial therapy was the most sensitive proxy indicator, identifying 95.5% of patients with HAIs.
HAI prevalence in this pilot was similar to that reported in the 1970s from CDC’s Study on the Efficacy of Nosocomial Infection Control. Antimicrobial therapy was a sensitive screening variable with which to identify higher-risk patients and reduce data collection burden. Additional work is needed on validation and feasibility to extend this methodology to a national scale.
