Technical efficiency and total factor productivity measurement of Social Security Institution hospitals transferred to Ministry of Health of Turkey The purpose of this study, we analyse the changes in the technical efficiencies, production performances and total factor productivity of the Social Security Institution (SSI) general hospitals transferred to the Ministry of Health (Moll) within the context of the Health Transformation Program are measured comparatively over the period 2004-8. The efficiencies of a sample of 46 general acute SSI hospitals have been comparatively examined before and after the transfer to the Moll. DEA was employed with included inputs being the number of physicians, nurses, other employees and staffed beds, whereas outputs were the inpatients, outpatients and surgical operations performed. The analysis indicates a considerably improvement in the productivity over the period considered. The results of the measurement show that there is a progress of 15% in the total factor productivities of SSI hospitals over the 2004-8 periods that is technological change plays a determining role in this progress.
