Abstract:Objective：To analyze the causes of high incidence cases in a certaincancer hospital throughout the year and propose measures to reduce the incidence of high incidence cases. Methods：The inpatient cases included in the DRG settlement in acertain cancer hospital from January to December 2022 were extracted，and 1，602 high rate cases were selected. Eight disease groups with more than 50 high rate cases were selected. 907 high rate cases were obtained and re-coded. The high rate cases were divided into two parts，coding reasons and non coding reasons，and the reasons were further analyzed. Results：Among the 907 cases with high magnification，384 cases were caused by coding reasons，mainly including incorrect selection of main diagnosis，incomplete filling of complications，incomplete filling of procedures，and incorrect filling of surgical/operational sequence. 523 cases were caused by non coding reasons，mainly including chemotherapy and targeted synchronous treatment，minimally invasive surgery/radiotherapy with high cost/high proportion of high value consumables，complications/complications，and unreasonable use of auxiliary drugs. Conclusion：Hospitals should strengthen DRG policy training，focus on clinical pathways，standardize diagnosis and treatment behavior，achieve DRG fee control，and achieve improved quality and efficiency of medical services. Emphasize coding work，introduce information systems，and achieve accurate clinical filling，accurate medical record compilation，and complete information transmission，truthfully reflecting the clinical diagnosis and treatment process. At the same time，it is also necessary to communicate，negotiate，and negotiate with the medical security administrative department to obtain policy support.
