Using senior residents as standardized patients for evaluating basic clinical skills of medical students

The use of standardized patients (SPs) is a powerful method for performance evaluation in medical education. It has gained increasing popularity in teaching and evaluation of clinical skills of medical students in the last decade. Maintaining an active and effective SP program requires a tremendous amount of financial and manpower investment, which may be difficult for many medical schools to provide. This study investigated the feasibility and effectiveness of using senior residents as SPs (SRSPs) to alleviate the financial and manpower burdens of an SP program.

A total of 112 fifth year medical students and 26 third year senior residents from a university hospital participated in this research in 2000. Students at the end of a 9-week rotating clerkship in internal medicine formed groups of 7 members. Senior residents took multiple roles as case developers, SPs, teachers, and evaluators. Test and recess stations were integrated, and sequential individual and group discussion with SRSPs was used to provide feedback immediately after the completion of the examination. Students were given a test report including scores and written narrative feedback. Semi-constructive questionnaires were used for opinion survey from students as well as the SRSPs.

All SRSPs demonstrated their ability to function in multiple roles and regarded the SRSP experience as helpful to improve this ability. Most SRSPs (89%) considered the experience beneficial in improving their clinical teaching skills. Ninety percent of SRSPs thought that a case should be portrayed for no more than 4 hours in order to maintain the consistency and accuracy. Seventy two percent of medical students reported that SRSPs' status as teachers did not interfere with their performance, 68% reported being able to treat SRSPs as real patients, and 96% reported that the evaluation was helpful to their professional development.

An SRSP program is feasible, practical, and easy to establish. It can provide benefits to both students and senior residents with clinical training responsibilities, and serve as an alternative method for performance evaluation of students in medical schools with limited resources.
