Measurement of Economic Efficiency of CCUs of Tehran University of Medical Sciences Hospitals, Using Data Envelopment Analysis (DEA) and Stochastic Frontier analysis (SFA) Methods: 2006-2009

The way of spending resources affects operational costs of hospitals and efficiency of health care system. The performance of the CCUs has significant effect on reducing heart diseases mortalities. In addition، CCUs are important wards due to the nature of modern and advanced care they provide. In this cross-sectional study، all CCUs of hospitals of Tehran University of Medical Sciences were studied. First، data were imported into the Frontier 4. 1 software. After estimating the cost and production functions، economic efficiency of the SFA method was calculated. Then، data were imported into the DEAP 2. 1 software and economic efficiency was again calculated. The economic efficiencies calculated using the two methods were compared in the SPSS. The means of economic efficiency of the CCUs were 0. 59±0. 95 and 0. 95±0. 063 in the SFA and DEA methods، respectively. The economic efficiency was significantly more in the DEA method than the SFA method (P<0. 0001). The SFA and DEA efficiency measurement methods did not show similar results. The types of activities and samples affect the results of the measurements.
