Analysis on DRGs Grouping of Patients with Acute Pancreatitis Based on CHAID
Objective To analyze the home page information of acute pancreatitis patients in a tertiary hospital of Sichuan province,explore the grouping by DRGs and establish related hospitalization cost standards,so as to provide reference for the reform of DRGs medical insurance payment.Methods Single-factor rank-sum test and multiple stepwise linear regression were used to analyze the home page data of 1 844 patients with acute pancreatitis(K85)who were discharged from a tertiary hospital in Sichuan Province from January 1,2019 to December 312021.Grouping by DRGs was performed in patients with acute pancreatitis by decision tree model.Results The mean hospitalization cost of patients with acute pancreatitis was 13 736.2 yuan,and the median was 11 105.2 yuan.A total of 1 844 patients with acute pancreatitis were divided into 7 DRGs case groups by four classification nodes:length of stay,surgical treatment or not,severity of illness and complications,and the corresponding hospitalization cost stand-ards were formulated.Among them,the average hospitalization cost of the group with the highest cost was 30 104.4 yuan,the median was 29 434.3 yuan,and the upper limit was 59 180.8 yuan.The average hospitalization cost of the lowest group was 8 398.5 yuan,the median was 7 890.6 yuan,and the upper limit was 15 183.5 yuan.Conclusion DRGs cases of acute pancreatitis established by decision tree model can be grouped reasonably,and the hospitaliza-tion cost standard and disease weight developed in the study can be used as data reference for medical insurance pay-ment reform in this area.
