Abstract: Objective To explore the teaching effect and applicability of microsurgery primary training course for residents. Methods The data analysis method was adopted. A total of 39 residents who received standardized training in Peking University People's Hospital from March 2020 to March 2022 were selected as the research subjects. According to previous research, the primary training course of microsurgery was constructed. The primary training course of microsurgery was taught by a multidisciplinary team of clinicians. Theoretical knowledge assessment, operational skills assessment and questionnaire survey were used to evaluate the teaching effect and its scope of application. Independent sample t-test and analysis of variance were used for comparison between groups. Results The theoretical and practical scores among all 39 residents were (14.5±2.8) and (64.0±3.4), respectively. The total score was (78.7±3.8). The qualified rate was 100.0% (39/39), and the excellent rate was 53.8% (21/39). There was a statistically significant in the degree of microsurgical operation confidence of residents before and after the course [(1.3±0.6) vs. (2.9±0.9), P<0.001]. There was no statistically significant in the scores of residents among different departments, education background, years of training, previous skill training and relevant experience [for example, the scores of theoretical knowledge of residents with ≥3 years of residency and < 3 years of residency were[(14.7±2.7) vs. (14.4±2.9), P=0.741]; the score of operation skills assessment was[(64.2±4.2) vs. (63.9±2.9), P=0.776]. Residents also put forward suggestions such as increasing physical exercises and adjusting class time. Conclusions The teaching effect of the primary training course of microsurgery is good, which is helpful to popularize the knowledge of microsurgery among residents, train their microsurgery skills, and improve their operation confidence. The primary training course of microsurgery can be carried out among residents in different departments, educational background and training years. The primary training course of microsurgery still needs to be improved.
