INTRODUCTION
Hospitals are the most expensive health services provider in the world. Therefore, the evaluation of their performance can be used to reduce costs. The aim of this study was to determine the efficiency of the hospitals at the Kurdistan University of Medical Sciences using stochastic frontier analysis (SFA).
METHODS
This was a cross-sectional and retrospective study that assessed the performance of Kurdistan teaching hospitals (n = 12) between 2007 and 2013. The Stochastic Frontier Analysis method was used to achieve this aim. The numbers of active beds, nurses, physicians, and other staff members were considered as input variables, while the inpatient admission was considered as the output. The data were analyzed using Frontier 4.1 software.
RESULTS
The mean technical efficiency of the hospitals we studied was 0.67. The results of the Cobb-Douglas production function showed that the maximum elasticity was related to the active beds and the elasticity of nurses was negative. Also, the return to scale was increasing.
CONCLUSION
The results of this study indicated that the performances of the hospitals were not appropriate in terms of technical efficiency. In addition, there was a capacity enhancement of the output of the hospitals, compared with the most efficient hospitals studied, of about33%. It is suggested that the effect of various factors, such as the quality of health care and the patients' satisfaction, be considered in the future studies to assess hospitals' performances.
引言
医院是世界上最昂贵的医疗服务提供者。因此，对其绩效进行评估可用于降低成本。本研究的目的是使用随机前沿分析（SFA）来确定库尔德斯坦医科大学附属医院的效率。
方法
这是一项横断面回顾性研究，评估了2007年至2013年期间库尔德斯坦教学医院（n = 12）的绩效。采用随机前沿分析方法来实现这一目标。将病床数、护士人数、医生人数及其他工作人员数量视为输入变量，而将住院患者入院人数视为产出。使用Frontier 4.1软件对数据进行分析。
结果
我们所研究医院的平均技术效率为0.67。柯布 - 道格拉斯生产函数的结果表明，最大弹性与病床数相关，而护士的弹性为负。此外，规模报酬递增。
结论
本研究结果表明，就技术效率而言，医院的绩效并不理想。此外，与所研究的最高效医院相比，这些医院的产出能力提高了约33%。建议在未来研究中考虑各种因素的影响，如医疗质量和患者满意度，以评估医院的绩效。
