Analysis on the Structural Variation and Influencing Factors of Hospitalization Expenses of Patients with Colorectal Cancer Surgery
Objectives By analyzing the structural variation and influencing factors of hospitalization cost of patients with colorectal cancer surgery in a grade-three general hospital in Shanghai,so as to provide references for controlling the increase of medical cost for colorectal cancer,adjusting the cost structure of specialized diseases and improving the level of medical management.Methods The inpatient data of 3047 patients undergoing colorectal cancer surgery in a hospital from January 1st,2019 to December 31st,2021 were retrospectively analyzed,including the basic information of patients,types of medical insurance and medical expenses.Statistical description,structural variation and multiple linear regression were used to analyze the structural changes of hospital expenses in patients with colorectal cancer surgery and its influencing factors.Results The main items that caused the change of inpatient medical cost structure of patients undergoing colorectal cancer surgery were examination cost(CSV=36.03％),drug cost(CSV=31.01％)and operation cost(CSV=13.97％),and the cumulative contribution rate of the three was 81.01％.The tensile value of examination fee was the highest(5.30),followed by surgery fee(0.59),and the tensile value of pharmaceutical products was negative(-2.65).In the results of univariate analysis,gender,type of medical insurance,age and length of stay were all influencing factors,with statistical significance(P＜0.1);the results of multiple linear regression analysis showed that type of medical insurance,age and length of stay were the main influencing factors of total medical expenses,with statistical significance(P＜0.05)Conclusions We should strengthen the standardization of clinical diagnosis and treatment behavior,pay attention to the control of medical costs such as drugs and consumables,and pay attention to the health management of tumors,so as to rationalize the structure of medical expenses and reduce the burden of medical expenses on patients.
