The effects of experience as a rater upon the objective clinical skill examination

Abstract

Introduction : Our knowledge and competence would be improved after teaching or evaluating others.We presumed that the experience of evaluating others affect the knowledge and competence for a task. This study examinedthe effects of experience as a evaluator.Methods : 34 students were randomly allocated into the 2 groups. The one is the evaluator group and the other is theapplicant group. Before simulation, all of students were compared with 3 written tests and clinical performance examination. Allof the students were put into the task to make check list, so they knew the contents of 33 objective skill clinicalexaminations(OSCE). The applicant group had undergone 33 OSCEs. The evaluator group had evaluated the simulation groupwith check list. The evaluator group had executed same 33 OSCE on the next day. We compared the score of OSCEs between2 groups. We surveyed how much they thought their knowledge and performance were increased.Results : The applicant group were evaluated 33 object skills clinical examinations by the evaluator group. The evaluatorgroup acquired higher score than the applicant group in 21 clinical skill tests. The 12 clinical skill test score of the evaluatorgroup were higher than the applicant group significantly. But the applicant group were superior than the evaluator group in theonly 5 clinical skills significantly. The evaluator group was higher in 9 clinical skill test and lower in 7 clinical skills than theapplicant group. But it were not statistically significant(Figure. 1). 28 students answered the questionnaire about the increase oftheir comprehension, skill performance The average of their interest as an evaluator was 4.21(0.69). The average ofcomprehension extension after evaluation was 4.64(0.48). The average of skill improvement was 4.45(0.60)Conclusion : The experience as a evaluator can increase the understanding and the performance of clinical skills.
