Abstract:
BACKGROUND:A major obstacle in the wide implementation of objective clinical structured examinations (OSCEs) is their high cost, averaging $200 to $300 (Canadian dollars, CDN) per candidate and estimated at up to CDN$900 per candidate if all "hidden" administrative costs are included. METHODS:A detailed cost analysis of preparing and administering OSCEs at 1 institution was undertaken over 2 years. An 18-station, 6-minute-per-station OSCE was given to a 72-student third-year medical class. RESULTS:The total cost of the OSCE was CDN$5,010, or $70 per student. The key factors in reaching this significantly lower per-student OSCE cost included: judicious use of standardized patients, use of academic faculty for preparing and marking the stations, and decreased secretarial and other administrative costs. CONCLUSIONS:Data suggest that OSCEs can be set up with reasonable cost and limited resources even in smaller institutions. Cost should not be considered a major obstacle in implementing this excellent examination type in undergraduate medical education.
