Abstract: To understand the status and influencing factors of the implementation of the “Unification of Four Certificates” training program for clinical medical postgraduates in Shanxi Province, a self-designed questionnaire was adopted to investigate and analyze the basic information of Grade 2015 clinical postgraduates in Shanxi Province, the basic conditions of training, the effectiveness of clinical rotation, teacher training, existing problems and solutions. The Cronbach’s α reliability coefficient of the questionnaire was 0.89. The structural efficiency analysis showed that the KMO test value was 0.93, the Bartlett spherical test value was P<0.01, and the cumulative variance contribution rate was 64%. Results showed that 70.63% of the respondents chose “out of future employment consideration” as the reason for their participation in the “Unification of Four Certificates.”46.39% of postgraduates thought they had “considerable pressure” since they took part in standardized training. Most of the pressure came from “publication pressure”. 34.97% of people thought they had “more” clinical practice opportunities. At present,the system of the “Unification of Four Certificates” in Shanxi Province has been improved. The awareness and satisfaction of trainees are generally good, but there are many weak links, such as the arrangements of clinical rotation and the training modes.Hopefully, this investigation can provide reference for improving the future residents training system.
