The Impact of COVID-19 Pandemic on the Learning Outcomes of Medical Students in Taiwan: A Two-Year Prospective Cohort Study of OSCE Performance.

Background/aims: To avoid the negative impacts of the COVID-19 pandemic on clinical clerkship, supplemental teachings such as digital materials in the scenario-based distal simulations were implemented. This study utilized the OSCE (objective-structured clinical examination) to evaluate the impact of COVID-19 pandemic on the learning outcome of medical students from the regular group (class of 2020) and pandemic-impacted group (class of 2021).

Methods: All medical students serially took, firstly, the mock-OSCE, secondly, the mock-OSCE, and the national OSCE. Then, the serial OSCE scores were compared between groups.

Results: Although with similar scores in the first mock OSCE, the regular group ( = 78) had a higher average score in the national OSCE than the pandemic-impacted group ( = 80) (872.18 vs. 834.96, = 0.003). In terms of improvement, the performances of the regular group were also better than the pandemic-impacted group between the second mock OSCE and the national OSCE (79.10 vs. 38.14, = 0.014), and between the second mock OSCE and the national OSCE (125.11 vs. 77.52, = 0.003). While separating distinct genres, the regular group had more of a score increment in standardized patient-based stations between the second mock OSCE and the national OSCE (regular vs. pandemic-impacted: 57.03 vs. 18.95, = 0.003), as well as between the first mock OSCE and the national OSCE (75.97 vs. 26.36, < 0.001), but there was no significant difference among the skill-based stations. In particular, the scores of the emergency medicine associated station in the national OSCE of the pandemic-impacted group was lower.

Conclusions: Our study implies that the pandemic significantly hampered the learning outcomes of final year medical students in their clinical participation. Especially facing the COVID-19 pandemic, more supplemental teachings are needed to compensate the decreasing emergency medicine exposure.
