background and purpose: the emergency severity index (esi) triage system has been recommended by the ministry of health to classify patients at emergency departments. this study aimed to assess the validity of esi system (version 4) in the emergency department of a teaching hospital. outcome measures were hospitalization, emergency department (ed) length of stay, resource consumption, in-hospit...

Triage helps to classify patients at emergency departments to make the most effective use of resources distributed. What is more important is that accuracy in carrying out triage matters greatly in terms of medical quality, patient satisfaction and life security. As the numbers of patients in emergency departments increase, learning from the examples of abnormal diagnosis of triage in order to ...

Agent-based modeling and simulation (ABMS) has gained wide attention over the past few years. ABMS is a powerful simulation modeling technique that has a number of applications, including applications to real-world business problems [1]. This modeling technique has been used by scientists to analyze complex system-level behavior by simulating the system from the bottom up. The major application...

Hospital overcrowding is a major problem for healthcare systems around the globe. In order to better estimate future demands and adequate resources coping with such demands, statistical computerised modelling can be applied. This then allow administrators decision makers quantify impacts of various “what-if” scenarios on hospital performance measures. paper investigates application Discrete Eve...

Accurate modeling of the patient flow within an Emergency Department (ED) is required by all studies dealing with increasing and well-known problem overcrowding. Since Discrete Event Simulation (DES) models are often adopted aim assessing solutions for reducing impact this worldwide phenomenon, accurate estimation service time ED processes necessary to guarantee reliability results. However, si...

OBJECTIVES Triage processes are often used by Emergency Departments to sort patients according to urgency or type of service required. Triage may also be used in a broad spectrum of other health services and not just emergency departments. Triage systems may be used to ensure the most urgent patients get timely service, but do they have an effect on patient flow? METHODS We conducted a system...

Modeling and simulation have been shown to be useful tools in many areas of the Healthcare operational management, field in which there is probably no area more dynamic and complex than hospital emergency departments (ED). This paper presents an ongoing research, an Agent-Based modeling and simulation to design a decision support system (DSS) for the operation of Healthcare Emergency Department...

In healthcare systems, emergency departments (EDs) are the most vital elements, in that they provide critical and immediate healthcare services to the patients 24 hours a day. Patient satisfaction is a crucial concept and a practical tool for evaluating the performance of the EDs. This study presents a unique framework for the performance optimization of an emergency department in a big general...
