Abstract:
Objective To explore the application of DRG mortality risk stratification method in evaluating perioperative healthcare quality,analyzes the distribution characteristics and influencing factors of perioperative mortality patients,and provide decision-making support for reducing perioperative mortality.Methods Collect perioperative case data from a tertiary hospital in Jiangxi Province from 2021 to 2023,and classify the risk of death for different DRG group.A chi-square test was used for univariate analysis,and a logistic regression model was used to analyze the factors affecting perioperative patient mortality.Results Among the death cases,the medium-and high-risk groups accounted for the highest proportion(59.31%),and the ratio of male to female was 2.2∶1.0,the most cases were over 65 years old(57.60%),and the top five Core DRG disease groups are neurological disorders,circulatory disorders,early grouping disorders,digestive disorders,and hepatobiliary and pancreatic disorders.Critical condition,serious complications or comorbidities,operation grade,relative weight,age,gender,and hospital day were independent influencing factors of perioperative death.All differences were statistically significant(P＜0.05).Conclusion To reduce perioperative mortality risks,it is necessary to enhance the treatment capacity for critically ill patients,optimize the dynamic management mechanism for surgical grading,and strengthen the risk management of emergency surgical medical care.
