HSMR compares the actual number of deaths in a hospital with the average Canadian experience, after adjusting for several factors that may affect in-hospital mortality rates, such as the age, sex, diagnoses and admission status of patients. The ratio provides a starting point to assess mortality rates and identify areas for improvement.
