Analysis of Hospitalization Expenses for Four Types of Malignant Tumors in Sichuan Province Based on Gray Correlation and Structural Variation
Objectives This study aims to analyze the hospitalization expenses and structural changes of four types of malignant tumors in Sichuan Province to provide a reference for controlling medical expenses.Methods The gray correlation analysis method and the structural change method were used to comprehensively analyze the internal influencing factors and structural change trends of hospitalization expenses for four types of malignant tumors in Sichuan Province from January 1,2015 to December 31,2020.Results The average hospitalization costs for four types of malignant tumors in Sichuan Province showed an upward trend from 2015 to 2020,with lung malignant tumors showing the largest increase.Among the sub-expenses of the four malignant tumors,the most closely related ones were drug expenses.Except for lung malignant tumors,the largest VSV was the cost of consumables(20.51％),and the other three largest VSVs were all drug costs.The DSV of hospitalization costs from largest to smallest were lung malignant tumors(53.28％),gastric malignant tumors(29.37％),esophageal malignant tumors(26.48％),and bladder malignant tumors(23.26％).The largest contribution to structural changes in lung malignant tumors was the cost of consumables(38.27％),followed by the cost of drugs(37.69％).Gastric malignant tumors,esophageal malignant tumors,and bladder malignant tumors all contributed the most to the structural changes of drug fees,which were 43.40％,38.43％,and 42.31％respectively.Conclusions The average per-time cost of four types of malignant tumors in Sichuan Province is on the rise,and the increase is relatively reasonable.Patients with lung malignant tumors have the most severe financial burden.The policy of controlling drug fees and increasing value has achieved initial results,but the fee structure still needs to be optimized.At the same time,the cost of consumables continues to rise.Hospitals should continue to deepen the reform of zero markup on consumables and strengthen the refined management of consumables.
