OBJECTIVES This article explores the potential of discrete event simulation (DES) methods to advance system-level investigation of emergency department (ED) operations. To this end, the authors describe the development and operation of Emergency Department SIMulation (EDSIM), a new platform for computer simulation of ED activity at a Level 1 trauma center.(More)
In this study, a discrete-event simulation approach was used to model Emergency Department's (ED) patient flow to investigate the effect of inpatient boarding on the ED efficiency in terms of the National Emergency Department Crowding Scale (NEDOCS) score and the rate of patients who leave without being seen (LWBS). The decision variable in this model was(More)
The objective of our project was to improve the efficiency of the physical examination screening service of a large hospital system. We began with a detailed simulation model to explore the relationships between four performance measures and three decision factors. We then attempted to identify the optimal physician inquiry starting time by solving a(More)
OBJECTIVES Intravenous (IV) access in children treated in the emergency department (ED) is frequently required and often difficult to obtain. While it has been shown that ultrasound can be useful in adults for both central and peripheral venous access, research regarding children has been limited. We sought to determine if the use of a static ultrasound(More)
OBJECTIVE GlideScope(®) videolaryngoscopy (GVL) has been shown to improve visualization of the glottis compared to direct laryngoscopy (DL). However, due to the angle of approach to the glottis, intubation can still be challenging. We hypothesized that novice GVL users would be able to intubate faster and easier using an airway introducer (frequently known(More)
BACKGROUND High-fidelity patient simulation has been praised for its ability to recreate lifelike training conditions. The degree to which high fidelity simulation elicits acute emotional and physiologic stress among participants - and the influence of acute stress on clinical performance in the simulation setting - remain areas of active exploration. We(More)
INTRODUCTION — Airway management is an essential skill for clinicians caring for critically ill or injured patients and is fundamental to the practice of emergency medicine. In emergency medicine practice, rapid sequence intubation (RSI) is the most frequently used and successful means of intubating the trachea [1-6]. It is employed in approximately 70(More)
OBJECTIVES Airway management is a critical procedure performed frequently in emergency departments (EDs). Previous studies have evaluated the complications associated with this procedure but have focused only on the immediate complications. The purpose of this study is to determine the incidence and nature of delayed complications of tracheal intubation(More)
BACKGROUND Simulation has been identified as a means of assessing resident physicians' mastery of technical skills, but there is a lack of evidence for its utility in longitudinal assessments of residents' non-technical clinical abilities. We evaluated the growth of crisis resource management (CRM) skills in the simulation setting using a validated tool,(More)
The objective of our project was to improve the efficiency of a screening physical examination service of a large hospital system. We began with a detailed simulation model to explore the relationships between four performance measures and three decision factors. These included various dispatching rules, physician starting inquiry time, and scheduled(More)
