Background and Aim: Pressure ulcer is a common problem and a large drain on hospital resources, especially in wards such as ICU where patients stay for a long time. The aim of this study was to explore the likely factors contributing to pressure ulcers in the ICU units of Tehran University of Medical Sciences teaching hospitals, Tehran, Iran.

Materials and Methods: This project was conducted in all the seven ICUs of four teaching hospitals affiliated to Tehran University of Medical Sciences. In the first phase the researcher performed a direct observation of all the 90 patients who were admitted to the ICU units to check the presence of any pressure ulcer. In the second phase, 310 patients discharged from the same ICU units between March 2007 and February 2008 was randomly selected and their medical records reviewed. A structured questionnaire was used to collect the data.

Results: Pressure ulcer occurred more frequently in the elderly women patients who were less active and had less mobility, hospitalized for a long time, or those with fever, diabetes, high blood pressure, paralysis, or respiratory diseases. In addition, pressure ulcer was seen more frequently in the patients hospitalized in the general ICUs, as well as in those with infections and different types of tumors.

Conclusion: Using a standard risk assessment tool and paying attention to the main risk factors of pressure ulcer can be a useful method for identifying the high-risk patients before admission in order to prevent them from developing such ulcers.

Background and Aim: 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.
Materials and Methods: 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.
Results: 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.
Conclusion: 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.
