The hospital standardized mortality ratio (HSMR) is an important measure to improve patient safety and quality of care in Canadian hospitals.

The HSMR adjusts for factors that affect in-hospital mortality rates, such as patient age, sex, diagnosis, length of stay, comorbidities and admission status. It then compares the actual number of deaths in a hospital with the average Canadian experience. The ratio provides a starting point to assess mortality rates and identify areas for improvement to help reduce hospital deaths.

When tracked over time, the ratio can be a motivator for change. The HSMR indicates how successful hospitals and health regions have been in reducing inpatient deaths — leading to improved patient care. CIHI has led the effort in calculating HSMRs for Canada and publishes results for eligible facilities and regions in all provinces and territories.
