  Introduction: There is no doubt that determining the efficiency of hospitals is one of the key steps that must be taken. Therefore, performance appraisal can help health plan executives to better understand its strengths and weaknesses. The purpose of this study is to evaluate the effect of health system transformation plan on the efficiency of selected hospitals in Ahvaz in the period 2012 to 2017. Methods: Data related to seven hospitals implementing the project and one control hospital in 2012, 2013, 2016 and 2017 were collected. The efficiency of hospitals was calculated using data envelopment analysis technique using CCR method and WinDeap2 v 2.1 software. Independent t-test and Poisson using Stata v 15.1 software were used for inferential analysis. Results: The highest efficiency of hospitals were related to 2017 with average 0.987 and the efficiency of two hospitals in 2016 and 2017 was 1 and the other two hospitals have experienced an upward trend during these two years. Efficiency, number of hospital admissions, number of outpatient admissions and number of surgeries before the transformation plan were significantly different from after, but this difference was not true for the number of active beds, number of physicians and number of nurses. Conclusion: Totally the efficiency of hospitals implementing transformation plan has been experienced an upward trend. considering the health system transformation plan in 2014, the improvement of the efficiency, the number of outpatient admissions, the number of hospital admissions and the number of surgeries was probably due to the transformation plan.

  Continuous growthing  in  the service part is an important subject  in the developed economic and competition world. Thus assessment of efficiency and productivity and recognizing the activity of parts are an important aim for an organization to reach the targets point. So , this study illustrates the efficiency, productivity and ranking of the insurance s parts of tamin-e-ejtemae with two approach: Data Envelopment Analysis(DEA) & Malmquist  and comparing  these two methods. The main targets are recognizing   inefficiency parts , peers for them, input slacks and determining  how is the return to scale(CRS or VRS). For exact assessment of  efficiency  and ranking , all of the insurances parts in Tehran (31 DMU) has been considered during 1385-1386. The reasons under VRS show that the average of scale efficiency, X- efficiency and technical efficiency are 0.786, 0.921, 0.731 , so scale inefficiency X- inefficiency and  technical inefficiency are 0.214, 0.79, 0.269. Under the Malmquist  approach although  scale efficiency, X- efficiency and  technical efficiency decreased , the technological efficiency had better result than another . Totally productivity has the positive process and 4% has growthed . So the first hypothesis confirmed that the reasons of the efficiency, ranking and productivity in the insurances parts are similar with DEA and Malmquist approach. The second hypothesis did not confirm that the level of the efficiency has equivalent with the ranking of insurances parts. In this study, targets show that parts of insurance can increase efficiency with decrease inputs, so the third hypothesis has confirmed Manuscript profile
