Hospitalization Cost Analysis of Patients Undergoing Laryngeal Cancer Surgery Based on Grey Correlation Method and Structural Variation
Objectives To analyze the average hospitalization cost and its composition of patients undergoing laryngeal cancer surgery,and explore the main affected cost items,so as to provide reference for controlling medical cost and reducing the economic burden of patients.Methods Grey correlation and structural change analysis were used to analyze the hospitalization costs of 2418 patients with laryngeal cancer from January 1st,2019 to December 31st,2023.Results The average hospital expenses of patients undergoing laryngeal cancer surgery fluctuated up and down.The top four factors influencing the correlation degree of the average inpatient cost were diagnostic cost(0.952),correlation degree(0.952),material cost(0.909),operation cost(0.902)and drug cost(0.899).The total structural variation of inpatient cost was 19.54％,among which drug cost showed a negative change year by year,and diagnostic cost showed a positive change year by year.Except for the negative change from 2022 to 2023,the operation cost changed positively in other years.The top three contribution rates of the structural change of hospitalization cost are drug cost,diagnosis cost and operation cost,with a cumulative contribution rate of 89.2％.Conclusions The structure of hospitalization cost was becoming more and more reasonable.However,drug costs,diagnostic costs and operation costs were the main factors affecting the hospitalization costs of patients undergoing laryngeal cancer surgery,among which there was still room for optimization of diagnostic costs.At the same time,strengthening the publicity of laryngeal cancer,early detection and early treatment were also effective means to control hospitalization costs.
