Between October 30 and November 5, 1980, the Professional Association of Interns and Residents of Ontario called a strike of house staff in Ontario's teaching hospitals. The authors obtained data concerning utilization of laboratory tests and radiology procedures during that period and for the same days 2 weeks before and after the strike. During the strike period, the number of tests performed per patient day decreased by only 8.3%. After accounting for proportional changes in emergency and nonemergency admissions, there was no significant change in the number of tests or relative value units performed per patient day as a result of the strike. These results suggest that the volume of tests performed in teaching hospitals is more likely related to the case mix and severity of illness of patients admitted to these institutions than to a pure "teaching effect."
1980年10月30日至11月5日期间，安大略省实习医生和住院医生专业协会号召安大略省教学医院的住院医生举行罢工。作者获取了该期间以及罢工前后两周相同日期的实验室检查和放射学检查的使用数据。在罢工期间，每位患者每日进行的检查数量仅减少了8.3%。在考虑了急诊和非急诊入院人数的比例变化后，罢工并未导致每位患者每日进行的检查数量或相对价值单位出现显著变化。这些结果表明，教学医院进行的检查数量更有可能与这些机构收治患者的病例组合和疾病严重程度有关，而不是单纯的“教学效应”。
