目的 制定合理的病种费用控制标准,加强病种质量管理和病种费用控制。方法 调查了某医院1999年全年出院病人病案,对667个病种、1518个病型、26668份病案,进行了病例分型可行性试验、正态性分布检验和建立标准的统计方法选择等多层次分析。结果 实验研究表明,由于病人病情差异等因素,同种疾病的平均住院日与医疗费用均呈偏态分布。讨论 通过算术均数和中位数2种方法比较,认为采用中位数作为病种质量费用控制的标准参考值以及上、下界限控制值为妥。
Objective To establish a reasonable disease cost control standard and strengthen disease quality management and disease cost control. Methods The hospital’s medical records of patients discharged from hospitals in 1999 were investigated. Among 667 disease cases, 1518 disease types and 26668 disease cases, a case-by-case feasibility test, a normality distribution test, and a standard statistical method were selected. Multi-level analysis. RESULTS: Experimental studies showed that the average length of hospital stay and medical expenses for the same disease were skewed due to factors such as the patient’s condition. DISCUSSION By comparing the mean and median methods, it is considered that using the median as the standard reference value for the control of the quality of the disease and the control values of the upper and lower limits are appropriate.
