Abstract:
Objective:To explore the application value of objective structured radiology examination (OSRE) in clinical skills assessment of medical imaging technology, and evaluate the repeatability of the assessment tool.Methods:A total of 55 interns majoring in medical imaging technology were randomly divided into 11 groups (5 in each group), and 9 different cases of OSRE were designed. Each student had to complete 3 cases of OSRE. Five senior attending doctors or deputy chief physicians independently evaluated each case of OSRE. Two months after the internship, three cases of OSRE were randomly selected for scoring to evaluate the internal consistency between raters and the repeatability of the evaluation method. SPSS 16.0 was used for statistical analysis, and multiple linear regression was used to analyze the correlation between academic qualifications and OSRE scores.Results:The OSRE average score of all the students was (12.0±4.9), and the average ICC range between evaluators was 0.36 to 0.80 ( P < 0.001). The consistency of 6 cases was good, that of case 3 was poor, and that of cases 6 and 7 was moderate. After 2 months, the ICC of 4 raters was equal to or greater than 0.8 (excellent consistency), and the ICC of rater 3 was 0.68, and the average original score difference ranged from -1 to 0.8. In multiple linear regression, the OR value of education was 0.90 (95% confidence interval 0.30-1.50, P = 0.01), and education was positively correlated with OSRE score. Conclusion:The OSRE aims to assess clinical skills and knowledge in a standardized clinical environment through the use of pre-set standard scoring scales, so that clinical knowledge can be evaluated in a high-level and repeatable manner.
