Background: Minimally invasive hysterectomy is generally preferable to abdominal hysterectomy. The technicity index (TI) is the proportion of hysterectomies performed by minimally invasive surgery. Many centers globally have started to audit local TI as a quality indicator, but only a handful have published their results to help define international standards of care. Objective: In this study, TI was examined in Winnipeg and Canada to determine consistency between local and national patterns of practice, audit expected changes, and contribute to the growing body of literature defining international standards of care. Methods: A retrospective cross-sectional database review of hysterectomies performed in the Winnipeg Regional Health Authority (WRHA) from 2008 to 2015 was conducted. Mixed effects linear regression models were generated primarily to analyze TI and account for surgeon and hospital characteristics. The Canadian Institute for Health Information (CIHI) database was accessed to estimate the average national TI from 2009 to 2014. One-sample t tests compared annual WRHA and CIHI TI. Results: In Winnipeg, 1363±32 hysterectomies were performed annually for all indications with an average TI of 34% independent of time (P=0.09). The CIHI database recorded approximately 27 000 hysterectomies annually with increasing TI (41%-52%, 3.5±1.8%/year, P=0.025). WRHA TI differed from national TI every year (P<2.2x10-16). Conclusion: Over the study period, WRHA TI was below the Canadian average and static despite national increases. The importance of local audits to identify underperformance and stimulate initiatives for quality improvement is highlighted in this study.
