Objective Structured Clinical Examination as A Reliable tool in the Summative Evaluation of Final Year Medical Students at Enugu State University College of Medicine

Objective structured clinical examination (OSCE) is a reliable, objective and reproducible method of summative assessment of clinical competence. The aim of this study is to evaluate the reliability of OSCE for summative evaluation of final year medical students in both Internal Medicine and Surgery. This was a retrospective cross-sectional study of summative assessment of final-year medical students in Internal Medicine and Surgery at College of Medicine, Enugu State University of Science and Technology. The students’ clinical competence was tested by OSCE. The OSCE consisted of two parts. The A part (picture OSCE, replacing traditional short cases) in which questions were given to students from slide shows. The B part (clinical OSCE, replacing traditional long case) consisted of clinical OSCE stations to test students’ ability and skills in history taking, physical examination, counselling/communication skills, ability to make diagnosis, interpretation of laboratory/radiological results and ability to manage common medical emergencies and conditions. The students' scores in the picture OSCE, clinical OSCE, and final total clinical score scores in both Internal Medicine and Surgery were collated and subjected to analysis with SPSS version 25 (IBM; SPSS, Chicago, IL, USA). Correlation was assessed by Pearson correlation, mean scores compared with paired t-test, reliability assessed by calculating Cronbach's alpha. Statistical significance was considered as p
