【摘要】 針對基本醫療保險患者住院費用上漲趨勢并未得到有效遏制的現狀,基于因子分析法展開研究,為加強患者住院費用管理和相關制度制定提供理論方法。以因子分析基本原理為依據,建立患者住院醫療費用構成體系,對初始數據進行KMO檢驗,運用SPSS 19.0軟件對所得數據進行統計分析,根據結果構建了因子分析模型。通過降維將12個費用構成指標抽象為化驗手術、藥品診察、麻醉輸血、護理治療和床位其他等5個因子表示,以較少的維度整合資料,能更好地簡化和解釋問題。

【Abstract】 For the present situation that the rising trend of basic medical insurance patients' hospitalization costs has not been effectively curbed,launching the research based on factor analysis methods to provide theoretical methods to strengthen patients hospitalization expenses management and related system formulation.Taking factor analysis basic principle as basis,established patients hospitalization medical expense constitution system,KMO test was carried out on the initial data,using SPSS 19.0 statistical software to carry out the data calculation,according to the calculation results constructed the factor analysis model.Through dimension twelve costs constitute indicators are abstracted as five factors of chemical examination surgery,medicine diagnosis,anesthesia and blood transfusion,nursing treatment and bed to express,integrating information in a lesser dimension,which is better able to simplify and explain problems.

我國醫療費用增長速度已經超過了國內生產總值的增長速度,“看病貴”和“看病難”問題日益嚴重,高級別醫療機構的醫療費用增長尤為突出,給國家、單位和個人造成了沉重的經濟負擔,制約著衛生事業的發展[1]。基本醫療保險保障了參保人員的基本醫療需求,但醫療費用上漲趨勢并未得到有效遏制,存在著醫療保險費用增長過快、醫療保險費用控制制度缺陷和費用支付結構不合理等問題[2-3]。本文將關系密切的醫療保險患者住院醫療費用構成指標歸在一類中,用少數幾個因子描述多個醫療費用指標之間的關系,簡化統計分析工作,為加強基本醫療保險患者住院費用管理和相關制度制定提供理論方法。
1 因子分析基本原理
因子分析就是基于降維的思想,把一些有錯綜復雜關系的變量歸結為少數幾個綜合因子的多變量統計分析方法[4-6]。……
