Prevalence of antibiotic-resistant organisms in Canadian Hospitals. Comparison of point-prevalence survey results from 2010, 2012, and 2016.

Objective: Point-prevalence surveys for infection or colonization with methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus (VRE), extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae, carbapenem-resistant Enterobacteriaceae (CREs), and for Clostridium difficile infection (CDI) were conducted in Canadian hospitals in 2010 and 2012 to better understanding changes in the epidemiology of antimicrobial-resistant organisms (AROs), which is crucial for public health and care management.

Methods: A third survey of the same AROs in adult inpatients in Canadian hospitals with ≥50 beds was performed in February 2016. Data on participating hospitals and patient cases were obtained using standard criteria and case definitions.

Surgical site infection surveillance for elective primary total hip and knee arthroplasty in Winnipeg, Manitoba, Canada.

Background: Surgical site infections (SSIs) increase morbidity and mortality after primary hip and knee arthroplasty. We evaluated a surveillance program that tracked risk factors associated with infection after primary hip and knee arthroplasty in the Winnipeg Regional Health Authority.

Methods: Surveillance data from April 2010 to March 2015 were reviewed for all 12,636 primary hip or knee arthroplasties, including 1-year follow-up.

Population-based surveillance of Clostridium difficile infection in Manitoba, Canada, by using interim surveillance definitions.

Objective: To apply interim surveillance definitions of Clostridium difficile infection (CDI) cases to 1 year of data from the provincewide surveillance system of Manitoba, Canada, to determine the epidemiology of CDI incident cases in a population.

Methods: CDI cases were categorized with interim surveillance definitions developed by an ad hoc C. difficile surveillance working group.
