Definition: Percentage of breast cancer mastectomies that were performed as day surgery.
Rationale for measurement: Reporting on mastectomies performed as day surgery allows detection of variations in practice across provinces, and helps to identify opportunities to improve patients’ experiences and reduce system costs by avoiding in-patient stays for patients who could safely recover at home.
Measurement timeframe:
Data were aggregated at national level: fiscal years 2008/09 to 2015/16
Data were aggregated at provincial level: fiscal years 2014/15-2015/16 combined
Denominator: Total number of mastectomies for women aged 18+ diagnosed with breast cancer
Numerator: The number of mastectomies performed as day surgery for women aged 18+ diagnosed with breast cancer
Exclusion criteria:
Women younger than 18 years of age
