Trends in healthcare-associated infections and antimicrobial-resistant organisms among adults in Canadian acute care hospitals: findings from four point prevalence surveys, 2002 to 2024.

ABSTRACT:

Objective

To describe trends in the prevalence of healthcare-associated infections (HAIs) and antibiotic-resistant organisms (AROs) in Canadian acute-care hospitals.

Design

Repeated point prevalence surveys.

Setting

Canadian Nosocomial Infection Surveillance Program (CNISP) hospitals.

Methods

Trained infection control professionals reviewed medical records of eligible adult patients and applied standardized definitions to collect demographic data and information on HAIs, AROs, and additional precautions from 39 to 62 hospitals in 2002, 2009, 2017, and 2024.

Results

The prevalence of adult patients with at least one HAI increased from 10.4% (95% CI: 9.6%-11.2%) in 2002 to 12.4% (95% CI: 11.7%-13.2%) in 2009, declined to 8.4% (95% CI: 7.8%-9.0%) in 2017, a
