Most Canadians who access health services receive safe care. However, sometimes there are adverse effects to receiving care — unintended harm associated with the delivery of care that can result in prolonged hospital stay, disability or death.

CIHI is working to help understand the issues related to patient safety and the provision of safe care, and is undertaking a large body of work in this area. We are also helping to measure improvements in the safety of care provided. Our work includes a number of initiatives, from the development and reporting of indicators across the continuum of care to other quality and patient safety analyses and initiatives.

One initiative, in partnership with the Canadian Patient Safety Institute External link, opens in new window, is a project on patient safety in Canada’s acute care hospitals. The resulting report Measuring Patient Harm in Canadian Hospitals, introduces a new measure of potentially preventable harm in hospitals. This 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 captured by the measure.

Key projects on patient safety

Databases and data sources for patient safety

The National System for Incident Reporting (NSIR) is a free, web-based reporting system used by Canadian health care facilities to securely and anonymously share, analyze and discuss medication and IV fluid incidents.

NSIR data and analyses inform quality improvement activities at all levels — from ward or unit projects to pan-Canadian initiatives — to foster improvements in health care delivery.

The Canadian Medication Incident Reporting and Prevention System (CMIRPS) External link, opens in new window is a collaborative pan-Canadian program of Health Canada, the Canadian Institute for Health Information (CIHI), the Institute for Safe Medication Practices Canada (ISMP Canada) and the Canadian Patient Safety Institute (CPSI).

CIHI has a number of other health services databases that contain quality-of-care information. More information can be found at CIHI’s Data Holdings webpage.
