To explore the reconstruction and practice of obstetrics and gynecology teaching clinic in undergraduate medical students' practice stage. Twenty-nine undergraduates(enrolled in 2017 5-year program and 2015 8-year program students) who joined internship in the Department of Obstetrics and Gynecology in September 2021 were selected as the research subjects. Obstetrics and gynecology teaching clinic mostly for training of undergraduates was carried out. Formative evaluation and feedback were implemented with mini-clinical evaluation exercise during the training process. At the end of the training, summative evaluation was performed by the standardized patient consultation evaluation table covered by objective structured clinical examination. A questionnaire was distributed to students to understand the teaching feedback. The items that scored low in formative assessment were physical examination (5.48±1.33), medical interview (5.90±0.80) and communication skills (5.93±0.69). The score rate of standardized test stations was (79.4±22.0)%. The items with a score of 0 were systematic consultation according to item sequence and summary in consultation process. The results of the questionnaire survey showed that in the improvement of medical record writing, physical examination, communication skills and organizational ability, 100.0%(29/29) students scored 5 points. In terms of clinical thinking improvement, 93.1%(27/29) students scored 5 points, and 6.9%(2/29) students scored 4 points. Students with an overall satisfaction score of 100.0%(29/29) were very satisfied. The implementation of obstetrics and gynecology teaching clinic provides a teaching platform for the training of clinical reasoning and communication skill. However, the repeated practice is necessary to fundamentally improve the clinical capacity of undergraduates during internship.
