Incidental appendectomy among elderly
Removal of the appendix at the time of another necessary abdominal surgery. This procedure is performed to eliminate the risk of future appendicitis (inflammation of the appendix). Incidental appendectomy is generally not recommended in the elderly because they have both a lower risk for developing appendicitis and a higher risk of complications after surgery (calculated for patients 65 years or older). Lower rates are more desirable.

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.
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.
