General practice outpatient teaching is one of the commonly-used teaching methods in clinical practice. At this stage, however, the general practice outpatient teaching activities in most clinical training bases in our country are only finished by general practitioners and general practice residents, and the connection with specialists and general practitioners in grassroots practice bases is not close enough. How to optimize outpatient teaching models and methods to further improve the post competence of general practice residents is currently a research hot spot.

To explore the application effect of general practice-specialty-grassroots practice base joints outpatient teaching in the standardized training of general practice residents.

A non-concurrent controlled trial was conducted, 24 general practitioner residents who underwent standardized training for general practitioners in Tongliao People's Hospital, Inner Mongolia Autonomous Region, from October 2019 to October 2021 were selected as the control group, and 23 general practitioner residents who underwent standardized training for general practitioners in Tongliao People's Hospital from November 2021 to October 2023 were selected as the experimental group. In the control group, general practice instructors conducted general practice outpatient teaching training once every 2 weeks, and in the experimental group, on the basis of general practice instructors, specialist and grassroots practice base instructors were added to conduct general practice-specialty-grassroots practice base joint outpatient teaching training, once every 2 weeks, and the training time for the two groups both is 2 years. After the training, the two groups of residents were assessed with the mini clinical exercise evaluation (mini-CEX) assessment scale and the "general practice reception skills evaluation table" to compare the training effects of the two groups.

In the experimental group mini-CEX, the scores of the seven assessment indicators in the assessment scale, namely medical history, physical examination, humanistic care, clinical judgment, health education and consultation, organizational effectiveness, and overall performance, were all higher than those in the control group, and the differences were statistically significant (P<0.05) . In the experimental group, the scores of the five assessment indicators in the general practice consultation skills evaluation table, including complete medical history collection, medical history inquiry skills, physical examination, health education, and reasonable consultation time, were all higher than those in the control group, and the differences were statistically significant (P<0.05) .

General practice-specialty-grassroots practice base jointed outpatient teaching activities can strengthen the clinical diagnosis and treatment thinking, communication and collaboration ability, and comprehensive service awareness of general practice residents by integrating multidisciplinary teaching resources, and effectively improve the training quality of general practice residents.
