Medical students' clerkship experiences and self-perceived competence in clinical skills.

Abstract

In a traditional curriculum, medical students are expected to acquire clinical competence through the apprenticeship model using the Halstedian "see one, do one, and teach one, approach". The University of Zambia School of Medicine used a traditional curriculum model from 1966 until 2011 when a competence-based curriculum was implemented. To explore medical students' clerkships experiences and self-perceived competence in clinical skills. A cross-sectional survey was conducted on 5th, 6th, and 7th year medical students of the University of Zambia, School of Medicine two months prior to final examinations. Students were asked to rate their clerkship experiences with respect to specific skills on a scale of 1 to 4 and their level of self-perceived competence on a scale of 1 to 3. Skills evaluated were in four main domains: history taking and communication, physical examination, procedural, and professionalism, team work and medical decision making. Using Statistical Package for Social Scientist (SPSS), correlations were performed between experiences and self-perceived competence on specific skills, within domains and overall. Out of 197 clinical students 138 (70%) participated in the survey. The results showed significant increase in the proportion of students performing different skills and reporting feeling very competent with each additional clinical year. Overall correlations between experience and self-perceived competence were moderate (0.55). On individual skills, the highest correlation between experience and self-perceived competence were observed on mainly medical and surgical related procedural skills with the highest at 0.82 for nasal gastric tube insertion and 0.76 for endotracheal intubation. Despite the general improvement in skills experiences and self-perceived competence, some deficiencies were noted as significant numbers of final year students had never attempted common important procedures especially those performed in emergency situations. Deficiencies in certain skills may call for incorporation of teaching/learning methods that broaden students' exposure to such skills.
