Summary
Radiology students showed poor skills in interpreting X-rays, correctly identifying only about half of normal and abnormal cases. Educators should integrate more clinical competency exercises for better film interpretation skills.
Area of Science:
- Medical Education
- Radiology
- Chiropractic Practice
Background:
- This study reports results from two administrations of a clinical competency examination in radiology.
- The examination was designed to assess radiologic interpretive skills crucial for chiropractic practice.
Purpose of the Study:
- To measure student aptitude in clinical film interpretation.
- To identify predictors of student success in radiology competency examinations.
Main Methods:
- An experimental design was used, administering two versions of a radiology competency examination to 210 chiropractic students.
- Linear regression and bivariate correlations analyzed predictors of student performance on the examination.
Main Results:
- Students correctly identified an average of 55-60% of normal and abnormal cases across both examination versions.
- Performance was lower in categorizing, managing, and naming identified pathologic conditions.
- Third-year radiology course grades and National Boards Part II diagnostic imaging scores were significant predictors of success.
Conclusions:
- Student performance indicates a need for enhanced radiology clinical competency training.
- Content-based radiology curricula may not adequately prepare students for clinical film interpretation.
- Educators should incorporate more practical film interpretation exercises to improve diagnostic skills.
