The Effect of Iran Health System Evolution Plan on Tehran University of Medical Sciences Hospitals’ Performance Indicators: a Case Study Using the Pabon Lasso Model

All hospitals need to be monitored and continuously evaluated. Pabon Lasso graphical model assesses the efficiency of hospitals using a combination of their input data and performance indicators. The aim of this study was to determine the effects of Iran Health System Evolution Plan on Tehran University of Medical Sciences (TUMS) hospitals’ performance indicators using the Pabon Lasso model in 2016. This was a descriptive-analytical and cross-sectional study including 8 general and specialized hospitals. The hospital input data and performance indicators were collected by permission of TUMS Vice-chancellor’s Office for Therapeutic Services. Chi-square and the two-sample T2 tests were used for data analysis, and hospital performance was assessed using the Pabon Lasso Model. The results showed that the number of TUMS hospitals located in zones 3 and 4 had increased after implementation of the Iran Health System Evolution Plan, which indicates improved efficiency of these hospitals, as confirmed by the chi-square test. Based on the Pabon Lasso graphical model, it can be concluded that the performance indicators of the hospitals show improvements in performance after implementation of the Iran Health System Evolution Plan. The successful experience in the management of the hospitals in this study can act as a practical guide for managers of other hospitals throughout the country for better management.
