Abstract

Background: Healthcare-associated infections (HAIs) continue to place a burden on patient health and safety as well as on the healthcare system. In Canada, national surveillance of HAIs at sentinel acute care hospitals is conducted by the Canadian Nosocomial Infection Surveillance Program. This article describes ten years of device and surgical procedure-related HAI epidemiology in Canada from 2011 to 2020. Methods: Data were collected from over 40 Canadian sentinel acute care hospitals between January 1, 2011, and December 31, 2020, for central line-associated bloodstream infections (CLABSIs), hip and knee surgical site infections (SSIs), cerebrospinal fluid shunt SSIs and paediatric cardiac SSIs. Case counts, rates, patient and hospital characteristics, pathogen distributions, and antimicrobial resistance are presented. Results: Between 2011 and 2020, 4,751 device and surgical procedure-related infections were reported, with CLABSIs in intensive care units (ICUs) representing 67% (n=3,185) of all reported infections. Over the surveillance period, significant rate increases were observed in adult mixed ICU CLABSIs (0.8 to 1.6 per 1,000 line days, p=0.004) while decreases were observed in neonatal ICU CLABSIs (4.0 to 1.6 per 1,000 line days, p=0.002) and SSIs following knee arthroplasty (0.69 to 0.29 infections per 100 surgeries, p=0.002). No trends were observed in the other reported HAIs. Of the 5,071 pathogens identified, the majority were gram-positive (68%), followed by gramnegative (23%) and fungi (9%). Coagulase-negative staphylococci (27%) and Staphylococcus aureus (16%) were the most frequently isolated pathogens. Conclusion: This report describes epidemiological and microbiological trends among select device and surgical procedure-related HAIs, essential for benchmarking infection rates nationally and internationally, to identify any changes in infection rates or antimicrobial resistance patterns and to help inform hospital infection prevention and control and antimicrobial stewardship policies and programs.
