Objective　To evaluate the effectiveness of medical practical training with a multi-level comprehensive model. Methods　We randomly selected 100 medical undergraduates who received practical training in The Affiliated Huai'an No.1 People's Hospital of Nanjing Medical University from 2017 to 2019

20 medical education experts

and 30 teachers for a questionnaire survey using self-designed questionnaire with 3 first-level items

8 second-level items

and 31 third-level items. Data processing and analysis was made by multi-level comprehensive model. Results　The comprehensive evaluation data (0.176 4

0.512 3

0.252 5

0.058 8) obtained by the multi-level comprehensive model showed that the proportions of medical undergraduates achieving excellent

good

moderate

and poor effects of medical practical training were 17.64%

51.23%

25.25%

and 5.88% respectively. According to the principle of maximum membership

the final comprehensive evaluation result of the effectiveness of medical practical training was good. Conclusion　This research has demonstrated the scientificity and feasibility of using the proposed multi-level comprehensive model to evaluate the effectiveness of medical practical teaching. In the comprehensive evaluation

the quantitative processing of qualitative indices can generate the matching score of each index in the multi-level index system. The evaluation results are intuitive and easy to analyze

thus providing the basis for the targeted improvement of medical practical teaching effect.
