目的探索影响4种外科单病种医保超支的因素,为控制医保超支提供参考。方法运用t检验、χ2检验、Logistic回归对某三甲综合性医院2009年1月1日-2009年12月31日出院患者的医保超支影响因素进行分析。结果年龄、住院天数、自费比例是影响4种外科单病种医保超支的共同因素。结论住院时间越长,医保超支的机率越大;年龄特征诱发医保超支;其他来自政府、疾病、医保制度以及医院管理方面的因素影响医保超支。
Objective To explore the factors influencing the overdraft of medical insurance for four kinds of surgical single diseases and to provide reference for controlling overdrafts of medical insurance. Methods The t-test, χ2 test and Logistic regression were used to analyze the influential factors of medical insurance overruns in discharged patients from January 1, 2009 to December 31, 2009 in a first-class general hospital. Results Age, length of hospital stay, and self-pay ratio were the common factors that affected the overdrafts of medical insurance for four kinds of surgical single diseases. Conclusions The longer the hospital stay, the greater the chances of medical insurance overruns. The age characteristics induce over-spending of medical insurance. Other factors such as government, disease, medical insurance system and hospital management affect medical insurance overruns.
