Volume indicators were not ranked since they have threshold requirements. Score The score indicates how well a hospital performs on a given indicator, based on its risk adjusted rate where a score of 100 is the highest. Risk adjusted rate Measures the observed rate adjusted for differences in patients’ age, sex, and the presence of complications. Observed rate Measures the outcome of interest compared to population at risk. Ontario average/total This value is the risk adjusted average (Ontario average) or total (Ontario total) of an indicator across all acute care hospitals in Ontario.
