四川省16866例肺癌患者住院费用影响因素分析

目的分析四川省16866例肺癌患者住院费用，发现肺癌患者住院费用的主要影响因素，为降低肺癌患者住院费用提供依据。方法综合考虑四川省各地经济水平及地理分布，选取四川省6家医院2008年1月～2011年12月肺癌住院患者的信息，从中提取基本信息、住院信息和费用情况，而后采用单因素方差分析和多元逐步回归分析对住院费用的影响因素进行研究。结果共收集肺癌住院患者16918例，有效16866例。统计分析结果显示：西药费为住院费用的最大构成，占平均总费用的50．79％；其次为诊疗费，占平均总费用的40．79％。多元逐步回归分析显示，对住院总费用影响最大的前三位因素依次为：住院天数、手术和地区。结论面对日益增长的肺癌住院费用，有效降低肺癌患者的西药费用是一个突破口。通过加强医院管理，从降低住院天数、规范合理用药和改变支付方式等几个方面人手，可最终降低肺癌患者的住院费用，减轻患者和社会的经济负担。

Influencing Factors of Hospital Costs of 16866 Cases of Patients with Lung Cancer in Sichuan

Objective Through the analysis of hospital costs of 16 866 cases of patients with lung cancer in Sichuan Province, in oder to find the main influencing factors of hospital costs of patients with lung cancer, and to provide refer- ences for reducing the hospital costs of patients with lung cancer. Methods We selected information of in-patients with lung cancer in 6 hospitals in Sichuan province from January 2008 to December 2011 based on full consideration into the local economic levels geographics distribution of different regions in Sichuan province. Then we extracted baseline data, hospitalization data and costs, and then analysis on relevant influencing factors was performed using single factor analysis of variance and multiple stepwise regression analysis. Results A total of 16 918 cases are chosen, of which, 16 866 were effective for further analysis. The results of statistical analysis showed that, the cost of western medicine accounted for the most of the average of the total hospital costs （50.79%）, followed by the cost of diagnosis and treatment （40.79%）. The reuslts of multiple stepwise regression analysis showed that, the top three factors influencing hospital costs most included hospital stay, operation, and regions. Conclusion Facing daily increasing costs of hospital costs of lung cancer, effec- tively reducing drug expenses of patients could be a breakthrough. We could ultimately reduce the hospital costs of pa- tients with lung cancer as well as the the economic burden of patients and society, by strengthening hospital management, shortening hospital stay, and rationally regulating drug use.
