In 1972 the College of Physicians and Surgeons of Saskatchewan appointed a committee to study hysterectomies because the Saskatchewan Department of Health had data showing that the annual number of hysterectomies carried out in the province had increased by 72.1 per cent between 1964 and 1971, whereas the number of women over 15 years of age had increased by 7.6 per cent. The committee compiled a list of indications for hysterectomy. Any hysterectomy carried out for one of these reasons was classified as justified, and the remainder as unjustified. Five hospitals were reviewed in 1970 and a further two in 1973. In 1974, all seven hospitals were reviewed again. In these hospitals, the average proportion of unjustified hysterectomies had dropped from 23.7 per cent at the time of the first review to 7.8 per cent in 1974. The total number of hysterectomies in the province dropped by 32.8 per cent between 1970 and 1974.
1972年，萨斯喀彻温省内科及外科医师学会任命了一个委员会来研究子宫切除术，因为萨斯喀彻温省卫生部的数据显示，1964年至1971年间，该省每年进行的子宫切除术数量增加了72.1%，而15岁以上女性的数量仅增加了7.6%。该委员会编制了一份子宫切除术的指征清单。因这些原因之一进行的任何子宫切除术都被归类为合理的，其余的则为不合理的。1970年对五家医院进行了审查，1973年又审查了两家。1974年，再次对所有七家医院进行了审查。在这些医院中，不合理子宫切除术的平均比例从首次审查时的23.7%降至1974年的7.8%。1970年至1974年间，该省子宫切除术的总数下降了32.8%。
