基于分位数回归模型的2型糖尿病足患者住院费用影响因素分析
Influencing factors of hospitalization costs in patients with type 2 diabetic foot based on a quantile regression model
摘要
Abstract
Objective To analyze the influencing factors of hospitalization cost in patients with type 2 diabetic foot based on health economics,thus providing evidence-based support for optimizing hierarchical diagnosis and treatment strategies for diabetic foot and the rational allocation of medical resources.Methods The data of 237 patients with type 2 diabetic foot hospitalized in Shanxi Provincial People's Hospital from 2022 to 2024 were collected.A quantile regression analysis was conducted to examine the determi-nants of hospitalization costs at the 10 th,50 th,and 90 th percentiles of its conditional distribution,and the importance of different influencing factors were ranked using a random forest model.Results The average total hospitalization cost for the 237 patients was 23 376.43 yuan,and the average hospital stay was 15 d.Univariate analysis revealed that age,occupation,length of hospital stay,treatment outcome,Wagner grade,and amputation(toe)status showed statistically significant differences in hospitalization costs for type 2 diabetic foot patients across subgroups(P<0.05).The number of surgery and the frequency of dressing changes were signifi-cantly positively correlated with hospitalization costs(P<0.001).Quantile regression analysis revealed that the length of hospital stay was the primary driver of costs,Wagner grade 4-5 was a key factor in increasing the financial burden for patients with median-level expenses,while the age of 40-59 years was a risk factor for extremely high costs.An increased number of surgical procedures signifi-cantly raised medical expenses in patients with low to median costs(10 th,50 th percentiles)(all P<0.05).The variable importance was ranked by random forest model as follows:hospitalization duration,number of operations,dressing change frequency,treatment efficacy,amputation(toe),employment status,Wagner grade,and age.Conclusion Based on quantile regression analysis,this study reveals that the hospitalization costs of patients with T2DF exhibit a heterogeneous distribution.Age,length of hospital stay,number of surgical procedures,and Wagner grade exert varying influences at different quantiles of hospitalization costs.关键词
