Abstract:

To enhance the competency of clinical medicine students in evaluating the severity of genetic disorders, this study first modularized an assessment of genetic diseases severity based on the World Health Organization's International Classification of Functioning, Disability and Health (ICF) framework. Then, this modular teaching framework was applied in teaching instruction. During the Medical Genetics course, the 2024 clinical medicine cohort at Hunan University of Medicine were clustered into a experimental group (6 classes, 203 students) and a control group (7 classes, 235 students) randomly. The experimental group engaged in the ICF-based module in the case analysis of genetic diseases, while students in the control group followed the traditional teaching methods. Learning outcomes were evaluated by analyzing the student-written genetic disease severity evaluation reports. Results demonstrated that students in the experimental group achieved significantly higher scores on their assessment reports (73.33±7.16) compared to the control group (64.79±5.45), with a statistically significant difference (t=13.87, P<0.001). Furthermore, textual analysis further revealed that reports from the experimental group contained a significantly higher frequency of keywords related to patient psychology, social functioning, and environmental factors, indicating a broader focus on the patients and more comprehensive and in-depth understanding of the patient’s situation. These findings suggest that the ICF-based modular teaching framework significantly improves medical students’ ability to conduct individualized assessments of genetic diseases and effectively fosters their humanistic care. This study provides an actionable and scalable teaching practice pathway for cultivating clinical genetic counseling professionals.
