Analysis of the Cost and its Influencing Factors of Orthopedic Inpatients in a Tertiary Hospital in Tianjin Based on Multiple Linear Regression Model
Objective To understand the cost components of orthopedic inpatients and their influencing factors,provides an effective basis for effectively controlling inpatient costs and improving the quality of medical services.Methods The disease composition ratio and total hospitalization cost of 12 887 orthopedic patients discharged from a tertiary hospital in Tianjin from January 1,2017 to September 30,2022 were statistically analyzed,and the factors influencing the total cost were modeled using a multiple linear regression model.Results The average age of 12 887 patients was(50.37±19.36)years old,and the peak age was 51-60 years old,accounting for 21.62％of the total number of patients,and the average annual growth rate of total hospitalization expenses was 6.29％.The multiple linear regression model showed that the increase of age,transfer,hospitalization days,number of disease diagnosis and number of surgical operations were positively correlated with the total cost of hospitalization.Ethnic minorities,outpatient admission,death signs and readmission within 31 days were negatively correlated with the total cost of hospitalization.The adjusted R2 was 0.801.Age,ethnicity,number of disease diagnoses and other indicators could explain 80.1％of the change in the total cost of hospitalization.Conclusion Ethnicity,age,route of admission,whether or not to transfer,length of hospital stay,number of disease diagnosis and number of surgical operations are the main factors affecting the total hospitalization cost of orthopedic patients.
