Leveraging feedback mechanisms to improve the quality of objective structured clinical examinations in Singapore: an exploratory action research study

Variability in examiner scoring threatens the fairness and reliability of objective structured clinical examinations (OSCEs). While examiner standardization exists, there is currently no structured, psychometric-informed, individualized feedback mechanism for examiners. This study explored the feasibility and perceived value of such a mechanism using an action research approach to co-design and iteratively refine examiner feedback reports. Two exploratory cycles were conducted between November 2023 and June 2024 with phase 4 OSCE examiners at the Yong Loo Lin School of Medicine. In cycle 1, psychometric analyses of examiner scoring for a phase 4 OSCE informed the design of individualized reports, which were evaluated through interviews. Revisions were made to the format of the report and implemented in cycle 2, where examiner responses were again collected. Data were analyzed thematically, supported by reflective logs and field notes.
