目的：利用通径分析探讨影响肺癌患者疾病负担及其可能的因素。方法：收集研究期限内安徽省某三甲综合性医院出院主诊断为肺癌的病例资料，采用描述性分析及通径分析探讨肺癌患者住院费用的影响因素。结果：25 817例肺癌的例均住院费用为18 816.91元，中位数为12 197.20元；例均住院日10.19 d，中位数为8 d。住院日是影响住院费用的主要因素，患者来源、手术情况、年龄、出院年份、入院病情以及出院转归还通过住院日间接影响住院费用；住院日、费用支付方式仅直接影响住院费用，而性别仅间接影响住院费用。结论：住院日是影响肺癌患者住院费用的首要因素，应以缩短平均住院日作为医院精细化管理的切入点，采取综合措施，合理减轻肺癌患者的疾病负担。
Objective:To explore the major factors influencing the medical expenditure of patients with lung cancer by the pathway analysis method.Methods: Descriptive statistics and the pathway analysis method was applied to inquiry the? factors?affecting hospitalization?costs?of?inpatients with primary diagnosis of lung cancer at a tertiary hospitals in Anhui province. Results:The average medical cost of 25 817 patients with lung cancer was 18 816.91 yuan with a median of 12 197.20 yuan,and the average length of hospital stay was 10.19 days with a median of 8 days. The length of hospital stay was the?foremost factor affecting hospitalization cost of inpatients with lung cancer directly,source of patients,surgical operation?situation, patients' age,the year of medical treatment,condition at admission and discharge had not only the direct effects but also indirect effects on the medical cost,the length of hospital stay,the expense payment forms only influenced the hospitalization cost directly,however,gender only had the indirect effects.Conclusion:The length of hospital stay is the main factor affecting the medical expense of patients with lung cancer,comprehensive steps should be taken,aiming to alleviate the economic burden of patients.
