The Canadian Nosocomial Infection Surveillance Program (CNISP):

  • Last updated: 2024-01-04

CNISP is a national collaboration between the Public Health Agency of Canada (PHAC), the National Microbiology Laboratory (NML), the Association of Medical Microbiology and Infectious Disease (AMMI) Canada, and hospitals across Canada. CNISP conducts prospective surveillance of healthcare-associated infections (HAIs) and antimicrobial resistant organisms (AROs) to inform evidence-based policies and control measures against antimicrobial resistance (AMR).

CNISP collaborates with sentinel hospitals across the country to collect epidemiologic and microbiology data on HAIs and AROs. Over the years, CNISP has significantly expanded, and it now conducts surveillance on 12 different pathogens in 106 hospitals across 10 provinces and 1 territory. In addition to monitoring HAIs and AROs, CNISP also collects and analyzes data on antimicrobial use, infection prevention and control practices, laboratory practices, viral respiratory illnesses including COVID-19, and emerging threats such as Candida auris.

Additional information on CNISP can be found in our overview publication: The Canadian Nosocomial Infection Surveillance Program: Keeping an eye on antimicrobial resistance in Canadian hospitals since 1995

NEW Simplified Dataset (SDS)

In 2022, CNISP launched the Simplified Dataset (SDS), which allows hospitals outside of the CNISP network to contribute aggregate data to CNISP’s rates. This project is currently being piloted with Clostridioides difficile infections (CDI) with plans to expand to other HAIs and AROs. By combining patient-level data from participating CNISP hospitals and aggregate data from the SDS, CNISP will have a more representative sample of Canadian hospitals, enabling the program to report national and regional rates of AMR with greater accuracy. With almost 100 hospitals actively participating in SDS surveillance, CNISP is rapidly expanding its representativeness across Canada.

CNISP is actively recruiting hospitals to participate in the SDS. If you are not already engaged with the CNISP network and would like to learn more about this new initiative or participate, please email
