Background:
The mini-clinical evaluation exercise (mini-CEX) has been used to assess clinical skills of 3rd-year medical schools. However a PDA-based mini-CEX has not been developed or evaluated before. Our objective was to determine the feasibility, implementation, and user satisfaction with a PDA-based mini-CEX.
Description:
Third-year medical students at the Medical College of Wisconsin who rotated on their core clinical clerkship in internal medicine during the period of July 2004 to April 2005 (n = 177) were required to complete two PDA-based mini-CEXs that were supervised by a faculty member or senior resident. Descriptive statistics and sample t test with equal variances were performed to analyze PDA-based mini-CEX completion rates, satisfaction scores by overall user and by evaluator type.
Evaluation:
During the 10-month study period, 354 PDA-based mini-CEX forms were collected (100% completion rate). Seventy-five percent (n = 267) of mini-CEXs occurred in the inpatient setting and 24% (n = 87) in the outpatient clinics. Students reported receiving feedback from their evaluator in 96% of these exercises. The most frequently evaluated competencies were humanism (90%), physical examination (90%), and overall clinical competence (90%). Third-year students were evaluated by residents in 58% (n = 205) of encounters and by faculty in 42% (n = 149). Residents rated students significantly higher than faculty (overall M = 7.6 vs. 7.1, respectively) in all clinical domains of the PDA-based form (p < .05). Satisfaction with the PDA based mini-CEX was high (scale = 1-9) for residents (8.1; SD = 1.5), faculty (7.4; SD = 1.5), and students (8.0; SD = 1.7).
Conclusions:
A PDA-based mini-CEX is a feasible tool to facilitate the direct observation of students' clinical skills. The PDA-based mini-CEX was highly rated by students and evaluators as a valuable technology-based tool to document direct supervision of clinical skills.
