Has novel coronavirus infection affected the professional identity recognised by medical students? - A historical cohort study

Introduction: The pandemic caused by the novel coronavirus (COVID-19) has produced dramatic changes in the learning environment for clinical practice in medical education, and the impact on medical students has been significant. However, few program evaluation studies involving professional identity, now emphasised in medical education, have compared current with pre-COVID-19 programs. Here, we compared the professional identity recognised by medical students in the years before and during COVID-19.
Methods: Medical students who participated in clinical practice were evaluated using the Japanese version of the Professional Self-Identity Questionnaire (PSIQ), a 9-item inventory rated using 7-point Likert scales. They answered on the first day of a 4-week clinical practice module within a community-based medical education (CBME) program and at graduation in 2018-2019 (pre-COVID-19 pandemic) and in 2019-2020 (during-COVID-19 pandemic). We compared the mean difference in total PSIQ score of the 2019-2020 students to those of the 2018-2019 students as a historical cohort using an unpaired t-test. 
Results: Participants were 104 medical students in the 2018-2019 academic year and 92 in the 2019-2020 academic year. PSIQ was increased at graduation. Mean difference in total PSIQ score was statistically higher for the 2019-2020 students (13.5 ± 9.4) than for the 2018-2019 students (10.3 ± 8.1) (t =2.6, df =195, p = 0.01).
Conclusion: Although clinical practice was restricted by COVID-19, this had some positive impact on the strengthening of professional identity recognised by medical students. This finding may have been influenced by the imprinting of professional norms and changes in society.
