INTRODUCTIONIt is crucial that medical students acquire appropriate clinical skills. These skills include the ability to gather and interpret information provided by patients, as well as the ability to formulate treatment plans based on medical knowledge obtained in preclinical/clinical courses and interactions with patients during their clinical clerkship. The clinical performance of medical students is expected to affect their future performance as doctors.In 1975, Harden et al (1) introduced a structured clinical examination that assessed the performance of medical students based on factors such as their skills, attitudes, problem-solving abilities and factual knowledge. The implementation of clinical skills examinations had a positive effect on the clinical performance of medical graduates. Medical graduates who passed a clinical skills examination were less likely to be judged as deficient when compared to those who had not taken the examination. (2,3) The relationship between the performance of medical students in clinical skills examinations and their actual performance as doctors (as rated by supervising directors) has yet to be definitively established. In one study, the clinical performance of students was found to be positively associated with their supervising consultants' assessment during their preregistration house officer year; however, this result did not reach the conventional levels of statistical significance.(4) In a different study, although statistical significance was also not shown, the score among all the parameters of the students' performance was found to be more correlated with the students' performance as first-year residents. On the other hand, one study showed that only the interpersonal score from the prototype examination correlated with the students' future performance as interns. (6) The Clinical Performance Examination (CPX) assesses communication skills, professional attributes, clinical skills and knowledge in realistic clinical encounters, (7) while the Objective Structured Clinical Examination (OSCE) measures technical skills. Thus, we hypothesised that the performance of a student in the CPX and OSCE could affect his or her performance as a doctor. The present study aimed to investigate whether the clinical performance of medical students, as measured by the CPX and OSCE, would be able to predict their performance as doctors in a clinical setting. This study also aimed to identify which component(s) of the students' performance in the CPX and OSCE was dominant in the relationship with their actual performance as doctors.
