医院作为卫生系统中消耗资源最多的中心，其绩效和效率因其功能的不同而存在差异。本研究旨在利用数据包络分析（DEA）方法评估阿瓦士医院的效率。
本研究是一项连续性分析研究，使用DEA评估了2006-2010年阿瓦士教学和非教学医院的效率。输入变量包括医生数量、护士数量和床位数量。输出变量包括住院床位占用率、手术次数、门诊人数、住院人数和住院时间。使用卫生和医学教育部制定的标准表格收集数据。采用DEAP 2软件对数据进行分析，采用独立样本t检验，计算各医院效率之间的差异。
研究期间医院的技术效率、规模效率和管理效率的均值分别为0.740、0.862和0.837。教学医院和非教学医院技术效率均值分别为0.557和0.873。结果表明，它们之间存在显著差异。
技术效率水平低于1级的医院投入和产出都比较松弛。因此，他们应该减少投入，以达到预期的最佳效率。
Hospitals as the centers that consume the most resource of health system, based on their function have difference performance and efficiency. The purpose of this study was to assess the efficiency of Ahvaz hospitals using data envelopment analysis (DEA) method.
This study is a descriptive-analytic study that assessed the efficiency of teaching and nonteaching hospitals in Ahvaz using DEA in 2006-2010. The input variables include the number of doctors, the number of nurses, and the number of beds. The output variables include inpatient bed occupancy, the number of surgeries, the number of outpatient, the number of inpatient, and length of stay. Data was collected using standard forms that have been made by Ministry of Health and Medical Education. Then data was analyzed by DEAP2 software and independent T-test, to compute the difference between the efficiency of hospitals.
The mean of technical, scale and managerial efficiency in hospitals during the period of study were 0.740, 0.862 and 0.837 respectively. The mean of technical efficiency in teaching hospitals and nonteaching hospitals were 0.557 and 0.873 respectively. The results showed a significant difference between them.
Hospitals with technical efficiency level less than one had slack inputs and outputs. So they should decrease their inputs in order to achieve the expected optimal efficiency.
