This project is a partnership between CIHI and the Canadian Patient Safety Institute (CPSI) External link, opens in new window aimed at answering the question “how often do patients experience harm in hospital?”

Updated  results for categories and types of harm, aggregated at the national level (outside of Quebec), can be found in the data tables (xlsx). 

Measuring Patient Harm in Canadian Hospitals (2016), introduced a new measure of potentially preventable harm in hospitals. The measure is linked to the Hospital Harm Improvement Resource External link, opens in new window which contains evidence-informed practices that can reduce the occurrence of harm. Providing an overview of the status of these patient safety events in Canada (outside of Quebec *), the report identifies how the data and associated improvement resource can be used for improvement.

Since the report release, CIHI has worked with stakeholders to further refine the methodology used to calculate hospital harm. The most current methodology can be found in CIHI’s Indicator Library

At this time, CIHI has no plans to develop hospital harm into a comparable indicator. CIHI will continue to work with stakeholders to ensure the information is helpful for improving patient safety in Canada.

The Hospital Harm Improvement Resource External link, opens in new window is a compilation of resources to complement the Hospital Harm measure. It links measurement and improvement by providing evidence-informed resources that will support patient safety and improvement efforts.

Through this collaboration, decision-makers, hospital executives, clinicians and policy-makers will have access to important information on patient safety in acute care hospitals and how to improve it.


* Data from Quebec is excluded due to methodological issues.
