ACGME Case Volume Minimums Decrease the Number of Shoulder and Knee Arthroscopies Performed by Residents

Orthopedic surgery residents reported increased shoulder procedure volumes during the COVID-19 pandemic

Background

The purpose of this study is to evaluate the impact of the COVID-19 pandemic on shoulder procedure volumes reported to the Accreditation Council for Graduate Medical Education by orthopedic surgery residents.

Methods

We performed a retrospective review of Accreditation Council for Graduate Medical Education case logs reporting data from graduating orthopedic surgery residents during the academic years of 2006-2022. Data were queried for all patients for the following shoulder Current Procedural Terminology codes: incision, excision, intro or removal, repair/revision/reconstruction, fracture and/or dislocation, manipulation, arthroscopy, trauma, and total procedures performed. Individual t-tests were used to compare case log trends of graduating academic years before (classes of 2018 and 2019) and during (classes of 2020, 2021, and 2022) the COVID-19 pandemic. Statistical significance was established to be P <.05 for total procedure types, but at P <.005 during category comparisons to protect against alpha errors.

Results

Reported mean total shoulder procedures per resident steadily increased each year from 2017 to 2022, but the only significant increase was seen when comparing the graduating classes of 2020 to 2021 (157.9 vs. 165.7, P =.02). Stratification of these procedures by subgroup revealed a significant increase in manipulation procedures from 2021 to 2022 (7.3 vs. 8.8, P =.001).

Discussion/Conclusion

COVID-19 did not have a negative impact on logged shoulder procedure volume. Orthopedic surgery residents graduating during the COVID-19 pandemic reported more shoulder procedures than those graduating prepandemic. However, shoulder procedure log trends should be longitudinally investigated, as preceding years of procedural opportunities may underestimate the pandemic's impact.
