INTRODUCTION We sought to investigate whether treatment of subnormal (<70%) central venous oxygen saturation (ScvO2) with inotropes or red blood cell (RBC) transfusion during early goal-directed therapy (EGDT) for septic shock is independently associated with in-hospital mortality. METHODS Retrospective analysis of a prospective EGDT patient database(More)
Integration of clinical decision support services (CDSS) into electronic health records (EHRs) may be integral to widespread dissemination and use of clinical prediction rules in the emergency department (ED). However, the best way to design such services to maximize their usefulness in such a complex setting is poorly understood. We conducted a multi-site(More)
INTRODUCTION We evaluated emergency physicians' (EP) current perceptions, practice, and attitudes towards evaluating stroke as a cause of dizziness among emergency department patients. METHODS We administered a survey to all EPs in a large integrated healthcare delivery system. The survey included clinical vignettes, perceived utility of historical and(More)
INTRODUCTION Informed consent is a required process for procedures performed in the emergency department (ED), though it is not clear how often or adequately it is obtained by emergency physicians. Incomplete performance and documentation of informed consent can lead to patient complaints, medico-legal risk, and inadequate education for the patient/guardian(More)
INTRODUCTION Central venous catheterization (CVC) can be an important component of the management of patients with severe sepsis and septic shock. CVC, however, is a time- and resource-intensive procedure associated with serious complications. The effects of the absence of shock or the presence of relative contraindications on undertaking central line(More)
INTRODUCTION The adoption of electronic medical records (EMRs) in emergency departments (EDs) has changed the way that healthcare information is collected, charted, and stored. A challenge for researchers is to determine how EMRs may be leveraged to facilitate study data collection efforts. Our objective is to describe the use of a unique data collection(More)
INTRODUCTION Much of the emergency medical research on sedation-assisted orthopedic reductions has been undertaken with two physicians--one dedicated to the sedation and one to the procedure. Clinical practice in community emergency departments (EDs), however, often involves only one physician, who both performs the procedure and simultaneously oversees the(More)
BACKGROUND Episodes of paroxysmal atrial fibrillation may be precipitated by the rapid ingestion of ice-cold foods and beverages. This condition has received little research attention, and its true prevalence is poorly described. Treating physicians may not identify cold ingestion as a causal factor of paroxysmal atrial fibrillation, thus compromising both(More)
Managers of service organizations seek to improve productivity without eroding service quality. We explore whether privately versus publicly disclosing relative performance feedback (RPF) about individual workers' processing times can help achieve this goal. Using three years of patient encounter data from two emergency departments, one of which changed(More)
