OBJECTIVE Emergency department (ED) intubation personnel and practices have changed dramatically in recent decades, but have been described only in single-center studies. We sought to better describe ED intubations by using a multi-center registry. METHODS We established a multi-center registry and initiated surveillance of a longitudinal, prospective(More)
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)
We describe the prevalence, primary indications and immediate complications of emergency cricothyrotomy (cric) techniques, in a single institution's Emergency Department (ED) and associated air-medical transport service. This is a retrospective review at an academic, level-one trauma center with an annual ED census of 65,000 and an associated air-medical(More)
This report describes a novel sonographic protocol for the evaluation of the undifferentiated hypotensive patient. This protocol combines components of 3 sonographic applications: free fluid, cardiac, and abdominal aorta into a single protocol. We believe this protocol and its underlying principles should be a routine part of the empiric evaluation of the(More)
STUDY OBJECTIVE We describe the operators, techniques, success, and adverse event rates of adult emergency department (ED) intubation through multicenter prospective surveillance. METHODS Eighteen EDs in the United States, Canada, and Australia recorded intubation data onto a Web-based data collection tool, with a greater than or equal to 90% reporting(More)
OBJECTIVES ST-segment elevation (STE) related to benign early repolarization (BER), a common normal variant, can be difficult to distinguish from acute myocardial infarction (AMI). The authors compared the electrocardiogram (ECG) interpretations of these two entities by emergency physicians (EPs) and cardiologists. METHODS Twenty-five cases (13 BER, 12(More)
The objective of this study was to assess the utility of emergency ultrasonography in the detection of blunt urological injury. A retrospective review was conducted of all consecutive emergency blunt trauma ultrasonograms (US) obtained at a level I trauma centre from January 1995 to January 2001. Among the 4320 emergency ultrasonograms performed, 596(More)
STUDY OBJECTIVE Glottic visualization with video is superior to direct laryngoscopy in controlled operating room studies. However, glottic exposure with video laryngoscopy has not been evaluated in the emergency department (ED) setting, where blood, secretions, poor patient positioning, and physiologic derangement can complicate laryngoscopy. We measure the(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)
