New guidelines from the Accreditation Council for Graduate Medical Education (ACGME) have proposed minimum case volumes to be obtained during residency. While radiology residency programs in Canada are accredited by the Royal College of Physicians and Surgeons of Canada, there are currently no minimum case volumes standards for radiology residency training in Canada. New changes in residency training throughout Canada are coming in the form of competency-based medical education. Using data from a pilot study, this article examines radiology resident case volumes among recently graduated cohorts of residents and determines whether there is a correlation between case volumes and measures of resident success.
Resident case volumes for 3 cohorts of graduated residents (2016-2018) were extracted from the institutional database. Achievement of minimum case volumes based on the ACGME guidelines was performed for each resident. Pearson correlation analysis (n = 9) was performed to examine the relationships between resident case volumes and markers of resident success including residents' relative knowledge ranking and their American College of Radiology (ACR) in-training exam scores.
A statistically significant, positive correlation was observed between residents' case volume and their relative knowledge ranking ( = 0.682, < .05). Residents' relative knowledge ranking was also statistically significant and positively correlated with their ACR in-training percentile score ( = 0.715, < .05).
This study suggests that residents who interpret more cases are more likely to demonstrate higher knowledge, thereby highlighting the utility of case volumes as a prognostic marker of resident success. As well, the results underscore the potential use of ACGME minimum case volumes as a prognostic marker. These findings can inform future curriculum planning and development in radiology residency training programs.
新的毕业后医学教育认证委员会 (ACGME) 指南建议住院医师在住院期间获得最低病例量。虽然加拿大的放射学住院医师培训计划由加拿大皇家内外科医师学院认证，但加拿大目前没有放射学住院医师培训的最低病例量标准。加拿大的住院医师培训正在发生新的变化，采用基于能力的医学教育形式。本文使用一项试点研究的数据，检查最近毕业的住院医师群体的放射学住院医师病例量，并确定病例量与住院医师成功指标之间是否存在相关性。
从机构数据库中提取 3 组毕业住院医师（2016-2018 年）的住院医师病例量。根据 ACGME 指南，为每位住院医师完成了最低病例量的实现。对 9 名住院医师进行 Pearson 相关分析，以检查住院医师病例量与住院医师成功指标（包括住院医师相对知识排名和美国放射学会（ACR）在培考试成绩）之间的关系。
观察到住院医师病例量与相对知识排名之间存在统计学显著正相关（ = 0.682， <.05）。住院医师的相对知识排名也与 ACR 在培百分位分数呈统计学显著正相关（ = 0.715， <.05）。
本研究表明，阅片量更多的住院医师更有可能表现出更高的知识水平，从而突出了病例量作为住院医师成功的预后指标的效用。同时，研究结果强调了将 ACGME 最低病例量作为预后指标的潜在用途。这些发现可以为放射学住院医师培训计划的未来课程规划和发展提供信息。
