Legend for Risk Adjusted Rates:
|
Better than the Alberta average for the selected year. |
|
Not different from the Alberta average for the selected year. |
|
Worse than the Alberta average for the selected year. |
|
| Craniotomy mortality rate |
|
|

DEFINITIONS:
| Rank |
All institutions were ranked on each indicator based on their scores, where the highest rank of 1 corresponds to the highest score out of 100. 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 outcome of interest compared to population at risk. |
| Alberta average/total |
This value is the risk adjusted average (Alberta average) or total (Alberta total) of an indicator across all acute care hospitals in Alberta. |
