HSMR is a measure of patient safety that compares a hospital’s mortality rate with a national standard. It has been proven useful in identifying areas that
can be changed to improve patient safety and the quality of care.
HSMR is a ratio of “observed” to “expected” deaths, multiplied by 100. A ratio greater than 100 means more deaths occurred than expected, while a ratio
less than 100 suggests fewer deaths occurred than expected. Note that HSMR is adjusted for factors affecting mortality (e.g., age, sex, length of stay) and
is based on diagnosis groups that account for 80% of deaths.
The Confidence Interval (CI) reported consists of a range of values (interval) that act as good estimates of the unknown population parameter. A Confidence
Interval of 95% means that if the HSMR calculation were repeated, the result would fall within the range identified 19 times out of 20.
Ontario hospitals report HSMR annually in December.
