Canadian Nosocomial Infection Surveillance Program

The Canadian Nosocomial Infection Surveillance Program is a national surveillance network that monitors healthcare-associated infections across Canadian provinces and territoryies. It coordinates multicenter epidemiologyic surveillance involving hospitals, laboratories, and public health agencies to detect trends in pathogen incidence, antimicrobial resistance, and outbreak occurrence. Working with a range of national and international partners, the program informs policy deliberations and clinical practice guidelines developed by health institutions and advisory bodies.

Overview

The program operates within a structure that links federal institutions such as the Public Health Agency of Canada with provincial ministries like the Ontario Ministry of Health and Alberta Health Services, tertiary care centres including Toronto General Hospital and Vancouver General Hospital, and academic centres such as the University of Toronto and McGill University. Surveillance activities mirror methodologies used by organizations like the Centers for Disease Control and Prevention and the European Centre for Disease Prevention and Control and contribute data to multinational efforts alongside the World Health Organization. Stakeholders include professional societies such as the Association of Medical Microbiology and Infectious Disease Canada, hospital infection control committees at institutions like St. Michael's Hospital, and laboratory networks including the Canadian Nosocomial Infection Surveillance Program's laboratory partners.

History and Development

Origins trace to provincial initiatives in the early 1990s, influenced by landmark events such as the SARS outbreak and policy shifts following inquiries like the Krever Commission. Founding collaborations involved municipal hospitals including Montreal General Hospital and public health units such as Toronto Public Health, with early methodologic models adapted from the National Nosocomial Infections Surveillance System and networks like the Canadian Hospital Epidemiology Committee. Over time the program expanded surveillance of device-associated infections in intensive care units at centres like St. Boniface Hospital and adopted standardized definitions paralleling those used by Public Health England and the European Antimicrobial Resistance Surveillance Network.

Surveillance Methods and Case Definitions

Case definitions rely on clinical, microbiological, and device-related criteria standardized across participant sites, comparable to definitions used by CDC NHSN and harmonized with WHO frameworks. Data collection integrates laboratory information systems at reference labs such as the National Microbiology Laboratory with electronic health record extracts from centres like Sunnybrook Health Sciences Centre. Active surveillance teams in infection control departments conduct chart reviews and device-day denominators at institutions such as Hamilton Health Sciences and Ottawa Hospital, while passive laboratory surveillance complements these efforts at community hospitals including Royal Victoria Hospital. Methods incorporate antimicrobial susceptibility testing standards established by organizations like Clinical and Laboratory Standards Institute and molecular typing performed at research centres including Institut national de santé publique du Québec.

Key Programs and Pathogen Surveillance

The program operates targeted modules for bloodstream infections, surgical site infections, ventilator-associated events, and Clostridioides difficile surveillance, with pathogen-specific streams monitoring organisms such as Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Enterococcus faecalis, Enterococcus faecium, Candida albicans, and Clostridioides difficile. Specialized surveillance for antimicrobial resistance tracks carbapenemase-producing Enterobacterales associated with genes like NDM-1 and KPC, and for methicillin-resistant strains paralleling work on MRSA outbreaks in healthcare settings such as St. Paul's Hospital. Collaborative projects have monitored influenza-associated hospitalizations in partnership with provincial influenza surveillance systems and sentinel hospitals like BC Children's Hospital.

Data Analysis, Reporting, and Impact

Analytic approaches employ statistical techniques used by academic groups at University of British Columbia and Université de Montréal for time-series analysis, risk adjustment, and benchmarking. Annual and periodic reports inform policy at ministries including the British Columbia Ministry of Health and influence clinical guidance from bodies such as the Canadian Paediatric Society and the Canadian Medical Association. Data have supported infection prevention interventions implemented at centres like Mount Sinai Hospital and policy instruments developed by the Canadian Patient Safety Institute, contributing to measurable reductions in device-associated infection rates and to antimicrobial stewardship initiatives promoted by Choosing Wisely Canada.

Governance, Funding, and Partnerships

Governance features partnerships among federal entities such as the Public Health Agency of Canada, provincial health authorities including Manitoba Health and Saskatchewan Health Authority, academic research institutes like the Hospital for Sick Children Research Institute, and professional organizations including the Infectious Diseases Society of America's Canadian affiliates. Funding streams combine public funding from agencies similar to the Canadian Institutes of Health Research with in-kind support from participating hospitals such as Centre hospitalier de l'Université de Montréal and laboratory networks including the Canadian Blood Services for transfusion-related surveillance. International collaborations include data sharing with the Pan American Health Organization and methodological exchanges with the European Society of Clinical Microbiology and Infectious Diseases.

Challenges and Future Directions

Ongoing challenges include harmonizing electronic health record data across sites like Health PEI and Newfoundland and Labrador Health Services, expanding genomic surveillance capacity at centres such as BC Centre for Disease Control Public Health Laboratory, and addressing emerging threats exemplified by outbreaks investigated at institutions like Hamilton General Hospital. Future directions emphasize integration with national antimicrobial resistance strategies, enhanced real-time reporting comparable to systems used by CDC and ECDC, and partnerships with research programs at universities like Dalhousie University and Queen's University to refine predictive analytics and machine learning for outbreak detection.
