Abstract:
Objective To explore the Diagnosis-Intervention Packet(DIP)group scheme and expense standards of patients with severe respiratory failure,so as to provide decision-making basis for optimizing the group of inten-sive diseases and improving the level of fine management of hospitals.Methods The homepage data of medical re-cords of 299 severe patients mainly diagnosed with respiratory failure from January to September in 2023 from a Grade A general hospital in Yangzhou City was collected,and the influencing factors of total hospitalization expenses were analyzed by single factor analysis and multiple linear regression.The exhaustive chi-square automatic interac-tion detector algorithm for decision tree model was used to establish the case-mix scheme of respiratory failure cases and calculate the expenses of each group.Results Hospitalization day,main surgery/operation,method of leaving hos-pital,and patient outcomes are important classification variables affecting the total inpatient expense of severe respi-ratory failure patients,finally formed 8 DIP groups and corresponding expense standards,with strong inter-group ho-mogeneity and great inter-group heterogeneity.Conclusion The optimizing group scheme of patients with severe re-spiratory failure based on decision tree model is consistent with clinical practice,and expense standard can objective-ly and comprehensively reflect the level of medical resource consumption,meanwhile,it will not greatly increase the burden of expenditure of medical insurance funds.So it can provide reference for the medical insurance government to optimize the group scheme of this disease,and also promote hospitals to improve the level of medical insurance fine management.
