摘　　要：目的了解骨科住院患者费用构成及其影响因素,为有效控制住院费用、提高医疗服务质量提供有效依据。方法对天津市某三甲医院2017年1月1日-2022年9月30日出院的12887例骨科患者的疾病构成比、住院总费用等指标进行分析,运用多元线性回归方程模型对总费用的影响因素进行建模分析。结果12887例患者平均患病年龄(50.37±19.36)岁,患病高峰年龄在51~60岁,占患者总数的21.62%,住院总费用年平均增长率为6.29%;多元线性回归方程模型显示,年龄增长、转科、住院天数增加、疾病诊断数和手术操作数增长与住院总费用呈正相关;少数民族、门诊入院、死亡标志以及31 d内再入院与住院费用呈负相关;调整R2为0.801,年龄、民族、疾病诊断数等指标能解释住院总费用变化的80.1%。结论民族、年龄、入院途径、是否转科、住院天数、疾病诊断数和手术操作数是影响骨科患者住院总费用的主要因素。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 12887 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 12887 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.
