Abstract
Introduction: Local emergency ward is designated to provision of treatment services for patients which is closely related to salvaging people’s lives. The main purpose is to apply simulation and improved treatment process procedure for appropriate designation of environment, resources and funds in the emergency ward and improvement of functional indexes. Methods: This is an applied-developmental study conducted during a one month period in 2012 on the patients referring to the emergency ward of Arak hospital and all the data were gathered through either observations or questionnaires consistent with the format of the Ministry of Healthcare. Both face content validity and stability of data were determined using the 93percent Cronbach's alpha factor. Non-probability purposive sampling is carried out with no prototypes to the number of 70350 case. The data analysis was conducted via Easy Fit software whereas simulation modeling was performed through Arena software. Results: Four different scenarios were simulated in this study using the Arena software, the results of which are presented both quantitatively and comparatively with respect to the functional indexes. The first scenario is considered as the prototype with a cost index of nearly 44 million units of of money and 37 percent care in the resuscitation ward, according to which the other three scenarios were designed and conducted. Conclusion: The results of this research show that the improved model would lead to more appropriate classification of work procedure and improvement of functional indexes in an emergency ward as compared with the previous model. Also, appropriate alteration in the number of resources and beds may improve the provision of services to the patients and resolve their dissatisfactions.
