The Canadian Nosocomial Infection Surveillance Program (CNISP)

Healthcare-acquired infections (HAIs), also known as nosocomial infections, are infectious diseases acquired in health care facilities such as hospitals. Many HAIs are caused by antimicrobial-resistant organisms (AROs), such as methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE). The Canadian Nosocomial Infection Surveillance Program (CNISP) is a sentinel surveillance system which collects epidemiologic and linked microbiology data from 90 Canadian acute-care hospitals across 10 provinces and two territories. CNISP summarizes trends in national incidence rates, antimicrobial resistance and molecular characterization for select HAIs and AROs.

The Canadian Nosocomial Infection Surveillance Program (CNISP) is a collaboration between the Public Health Agency of Canada (PHAC), including the National Microbiology Laboratory (NML), the Association of Medical Microbiology and Infectious Disease (AMMI) Canada, and acute-care hospitals across Canada.
