Abstract: Objective To analyze the practical cases, operations and DRGs index in the residents training bases of obstetrics in Beijing, and to set appropriate scientific evaluation standards for those bases. Methods Based on medical record information from 2014 to 2015 in Beijing residents training bases, we compared the practical cases and operations of the residents with the evaluation index system of standardized resident training bases of obstetrics and gynecology in Beijing.Results The total weight of DRGs in training bases is basically the same as the standard of diseases, and DRGs index can evaluate the training bases in terms of medical service efficiency and the difficulty of diagnosis and treatment. Both premature rupture of membranes and scar uterus were the leading cases in obstetrics disease, yet there is no corresponding requirements in the system. In terms of disease category, only four training bases were all up to standard, and the number of surgical cases was basically up to standard. The estimated the number of patients in both F hospital and the J hospital. The F hospital is slightly higher than the actual number of bearing, indicating both hospitals can bear more residency training tasks. Conclusions DRGs can be used to evaluate the standardized training bases for residents, and the number of diseases and operations should be further improved in the evaluation index system of obstetrics. The training bases can dynamically adjust themselves and the carrying number of people also need adjust correspondingly.
