[ estimation of technical efficiency of radiology wards in hospitals of Mashhad university of medical sciences using data exhaustive analysis method: 2006-2010]

Introduction: The Diagnostic Radiology ward is one of the most important parts of a hospital that has an important role in the detection of various diseases. This sector has a lot of startup costs. Since this ward is an income-earning ward of the hospital, in order to improve thequality of diagnostic radiology and direct resources to the most productive uses, the performance of this sector should be considered as a necessity. The aim of this study is estimation of technical efficiency of radiology wards of hospitals of Mashhad University of medical sciences using data exhaustive analysis method

Method: This research was conducted with a descriptive-analytical method in 2007 to 2011. The radiology wards of the hospitals of Mashhad University of medical sciences formed the study population. The input variable included number of personnel, physicians, equipment, and the output variables included income and the number of patients. The data were accumulated by author-devised forms

Results: Average of technical performance, managerial, and scale efficiency of the studied centers during the period of study was appointed 0.557, 0.942, and 0.567, respectively. The average technical performance efficiency of university hospitals' radiology wards was less than that of other non-affiliated hospitals. Only one radiology part which runs by private sector has full performance during the study

Conclusion: Centers which were more customer-oriented and tried more to comfort patients were more successful than other centers. Managers can increase motivation and thus efficiency by sharing income with some personnel

[ survey of health sector from the perspective of economics and its relationship with other sectors in Iran's economy]

Introduction: Health sector is one of the most important sectors in the economy of any country with its products being on demand by individuals and households. This study was done in order to survey the health sector in Iran's economy using input-output analysis

Methods: In this analytical study all economic sectors in Iran were compared using input-output Technique. Ultimately, linkages, importance index, dependency degree of health sector were computed among the 18 aggregated sectors

Results: Health sector does not have remarkable effect on other sectors because of low backward linkage. The low forward linkage has an inappropriate place in providing intermediate data. This sector has the highest degree of dependency on industry products and the lowest on the mining sector. The first sector depending on health is the health itself followed by education whereas the real estate sector has the lowest dependency on health

Conclusion: Having a coefficient less than one compared to other sectors, the health sector has a smaller role in inducing production processes and integrating the economy. Moreover, its motivation depends on other sectors' motivation. Also, the end products of health sector are consumed in final demand form
