Using audiotapes to monitor student-preceptor interactions in a decentralized clerkship.

BACKGROUND

Community-based preceptors are increasingly being used to provide clinical experiences for medical students; therefore, the issue of when and how to monitor the appropriateness of teacher-learner interactions in the clinical setting has become increasingly complex and urgent. This paper describes how an audiotaping program in a department of family medicine was designed to account for preceptor and student needs and what this audiotaping experience revealed about the teaching strengths and weaknesses of full-time and volunteer faculty.

METHODS

Audiotaped case discussions between third-year students and preceptors were evaluated using a structured instrument that reflected important responsibilities of clerkship preceptors. Reviews were compared using chi-square to evaluate for significant differences between university and community preceptors in overall quality of interaction with students and in specific deficiency areas. Ninety-five percent confidence intervals were used to evaluate for significant differences in frequency of occurrence among deficiencies.

RESULTS

A total of 376 audiotaped case discussions were reviewed between July 1992 and June 1994. University preceptors had significantly more "superior" interactions with students than their community peers (P < .05). However, university and community preceptors had nonsignificant differences when specific deficiency areas were compared. Deficiencies in students who were allowed to present cases and assessments occurred significantly less frequently, while deficiencies in preceptors using open-ended questions occurred significantly more frequently than deficiencies in other areas.

CONCLUSIONS

This study shows that volunteer faculty performed comparably to full-time university faculty in both the frequency of deficiencies in teacher-learner interactions identified and in the types of deficiencies identified. Both university and volunteer faculty had the most deficiencies in higher-order teaching skills--those involving synthesizing and assessing student knowledge and selecting appropriate questions based on that information. Audiotaped case discussions have a potentially significant role in monitoring teacher-student interactions, particularly on decentralized clinical rotations.
