Abstract

Objectives

The purpose of this study is to analyze the evaluation results and score deviation between interraters after performing ankle sprain CPX.

Methods

Ankle sprain CPX was performed on fourth-year students in the Department of Korean Medicine. A student standardized patient(SSP) filled out the 50-point PPI questionnaire.

Results

Ankle sprain CPX final score was 28.20 ± 1.40. Evaluation items showed low scores in the following order: performance time, physical examination, and past and social history check. The “physical examination” accounted for the largest proportion of the score deviation between interraters. In PPI, the lowest score was “effective questioning”, and the highest scores were “listening” and “empathy”.

Conclusions

We hope that follow-up research will be conducted to develop objective and reliable CPX evaluation standards and scoring checklists in the future.
