With the national emphasis on the innovative development of medical education, undergraduate teaching as the initiation stage of medical education has also attracted much attention.

Using the Kano model to explore the key elements of the quality reform of the undergraduate course, Introduction to General Practice, and to construct a quality optimization strategy.

Using purposive sampling method, 220 medical students who had completed the course of Introduction to General Practice in the fall semester of 2023 (5-year and long-term students of the class of 2021 in Capital Medical University majoring in clinical medicine, pediatrics, and optometry medicine) were selected as the target respondents. The questionnaire of the course content demand of Introduction to General Practice was used to investigate the students' demand for the course demand status, and carry out attribute categorization for each demand, Better-Worse coefficient analysis and average satisfaction coefficient (ASC) value analysis.

From the perspective of all students, among the 44 demand indicators, there were 3 must-be factors, 20 one-dimensional factors and 4 attractive factors. Clinical medicine students had 7 must-be factors, 1 one-dimensional factor and 5 attractive factors in their specific needs; pediatrics and optometry students had 5 must-be factors, 3 one-dimensional factors and 3 attractive factors in their specific needs. 5-year students had 1 must-be factor, 2 one-dimensional factors and 3 attractive factors in their specific needs; and long-term students had 4 must-be factors, 2 one-dimensional factors and 3 attractive factors.

Following the principle of making sure to satisfy the must-be factors, prioritizing the one-dimensional factors, selectively satisfying the attractive factors, and appropriately streamlining and adjusting the non-differential factors, the optimization proposals of course quality is constructed.
