Objective To explore the application effect of the four-dimensional teaching library model in the training of neuroinfection subspecialty continuing physicians, and compare it with traditional rotational training. Methods Continuing physicians who received training in the Department of Neurology of Xuanwu Hospital, Capital Medical University between March 2021 and February 2023 were selected. The continuing physicians who received traditional rotational training between March 2021 and February 2022 would serve as the control group, and the continuing physicians who received four-dimensional teaching library model training between March 2022 and February 2023 would serve as the experimental group. The Mini-CEX scale was used to evaluate the clinical comprehensive abilities of two groups of continuing physicians. At the same time, self-made questionnaires were used to evaluate the evaluation of two groups of continuing physicians on different teaching modes. Results A total of 55 continuing physicians were included. Among them, there were 27 people in the control group and 28 people in the experimental group. There was no statistically significant difference in the comparison of general information between the two groups (P＞0.05). At the time of graduation, all items on the Mini-CEX scale in the experimental group were higher than those in the control group (P<0.05). The survey questionnaire results showed that the experimental group scored higher than the control group in terms of improving learning interest, improving self-learning ability, improving clinical thinking, improving analysis and problem-solving ability, improving doctor-patient communication ability, and increasing teamwork (P<0.05). Conclusion The application effect of the four-dimensional teaching library model in the training of neuroinfection subspecialty continuing physicians is better than that of traditional rotational training, which can significantly improve the clinical comprehensive ability of continuing physicians and is worth promoting.
