Objective To explore and implement a systematic, case guided online interactive training course for neurologists to improve their diagnosis and treatment of rare genetic diseases. Methods Doctors who participated in the course investigation of the neurogenetic project of the Department of Neurology of Peking Union Medical College Hospital between January and September 2021 were selected. Based on andragogy theory, a genetics training course for neurologists was developed by applying Kern’s six steps of curriculum development. According to the time of participating in the doctor’s courses, they were divided into three groups: completed all courses (10.7 h group), completed more than 1/2 courses (5.3～10.7 h group) and completed less than 1/2 courses (<5.3 h). According to the length of service, they were divided into groups of less than 10 years, 10-20 years and more than 20 years. Analyze the benefit difference of different doctors’ training time, and collect their feedback scales on the curriculum for the improvement of follow-up courses. Results A total of 54 doctors were included. Among them, 17 (31.5%) completed all courses, 29 (53.7%) completed more than 1/2 courses, and 8 (14.8%) completed less than 1/2 courses. There was a statistically significant difference among the three groups in the self-assessment improvement score (H=12.341, P=0.002). The results of pairwise comparison between groups of self-assessment improvement score showed that the <5.3 h group was lower than that of the 10.7 h group (P=0.007), and the the <5.3 h group was also lower than that of the 5.3～10.7 h group (P=0.002). 33 (61.1%) in the less than 10 years group, 16 (29.6%) in the 10-20 years group, and 5 (9.3%) in the more than 20 years group. There was no correlation between participating in work and course time (rs=0.113, P=0.418). 54 (100.0%) believed that they had more than moderate help (≥3 points). Most doctors (>90%) had a good evaluation of the curriculum. Conclusion The periodic neurogenetic re-education project is helpful for clinical diagnosis and treatment of rare neurogenetic diseases.
