یک الگوریتم یکپارچه برای بهینه سازی عملکرد بخش های مراقبت ویژه جراحی مغز و اعصاب

This study presents an integrated simulation and data envelopment analysis (DEA) approach to increase the quality of service in a neurosurgical intensive care unit (ICU). The aim of this study is to capture the main factors which have negatively affects the patients’ satisfactions and figure out their optimized levels. In order to avoid any interruption in ICU's routine functions and being able to convince the hospital's principals about the project's outcomes, a simulation model is developed and run for different scenarios. Then DEA is used to compare the outputs of different scenarios. These scenarios are generated by observing the effects of various parameters such as lengthening or shortening treatment times, decreasing or increasing patient volumes and removing or adding staff members. As the best of our knowledge, this is the first study that presents an integrated approach based on computer simulation and DEA to concurrently incorporate the stated factors and parameters for optimization of complex ICUs in developing countries. Therefore, the results of this study are more precise and reliable than previous studies because of concurrent consideration of the stated factors.
