This study aims to explore the application value of the ″Establishing Health Records for Relatives and Friends″ practical teaching module based on WONCA job competencies in the Introduction to General Practice course, and to evaluate its effect on enhancing the six core competencies of medical students in general practice. The practical teaching module was designed around five tasks across four stages: ″establishment, assessment, intervention, and follow-up″, and was implemented after the course. Seventy undergraduate clinical medicine students were recruited to participate in the practice, of whom 56 completed all tasks and were included in the analysis. The improvement in students′ competencies was evaluated through objective scoring and structured questionnaires. The results showed that in the objective scoring, the distribution of student scores was as follows: 90-100 points, 10.7% (6/56); 80-89 points, 64.3% (36/56); 70-79 points, 25.0% (14/56). According to the questionnaire survey results, the proportion of students reporting ″greatly improved″ or ″significantly improved″ in 7 evaluation items, including ″clinical thinking and comprehensive analytical skills″ and ″promoting family health″, exceeded 55%. The ″Establishing Health Records for Relatives and Friends″ practical teaching module helps strengthen medical students′ understanding of the concept of ″family-centered health care″, enhances their core competencies in health record management, risk assessment, communication, and humanistic care, and demonstrates the advantages of integrating theory and practice in teaching.
