Abstract: Objective To explore the feasibility of using diagnosis-related groups(DRGs) to improve the level of disease management in Department of Geriatrics based on analysis of the abnormal cost of DRGs and training. Methods A total of 890 geriatric medical records of the discharged patients from January to June 2019 were collected,and all the abnormal cost records including extremely high cost records, very low cost records and ambiguous medical records were extracted. The geriatricians were trained based on the questions that acquired by the encoders and quality control doctors based on the DRGs principle. After training, a total of 685 medical records of the discharged patients from January to June 2020 were collected. The filling level in the medical record home page was evaluated. Results In the first half of 2019, the prevalence of the abnormal cases was 11.69% (104 cases), including 50 extremely high cost records (5.62%), 21 very low cost records (2.36%) and 33 ambiguous medical records (3.71%). The qualified rate of filling diagnosis and treatment in the medical record home page was 83.22%. The main reasons of abnormal medical records were choosing errors of diagnosis, omission of diagnosis, diagnosis or treatment name be not standardized and choosing errors of treatment. Compared with the first half of 2019, there were only 7 extremely high cost records (1.02%), 9 very low cost records (1.31%) and 4 ambiguous medical records (0.58%) in the first half of 2020 (all P＜0.05), and the qualified rate of filling in the home page was significantly enhaced (96.35 vs 83.22%, P＜0.05). Conclusions By the analysis of the abnormal typical cases and training based on the DRGs principle, the filling level in the medical record home page can be improved significantly, which reflects the improvement of diseases management level of Department of Geriatrics.
