Using data provided to CIHI over several years from Canadian hospitals, as well as other data sources, the website can measure a broad range of topics, including hospital readmission rates, rates of in-hospital infection from sepsis, avoidable deaths from treatable causes and hospital deaths following major surgery. Indicators of the health status of Canadians by province and region are also available, including average life expectancy at birth and at age 65, and the number of hospitalizations due to heart attacks and strokes.
