OBJECTIVES The goal of this study was to demonstrate that copeptin levels <14 pmol/L allow ruling out acute myocardial infarction (AMI) when used in combination with cardiac troponin I (cTnI) <99 th percentile and a nondiagnostic electrocardiogram at the time of presentation to the emergency department (ED). BACKGROUND Copeptin is secreted from the(More)
BACKGROUND : Hospitals measure patient satisfaction through Press Ganey (PG) surveys. The impact of an emergency department observation unit (EDOU) on patient satisfaction has not been reported to date. We hypothesize that an EDOU has a positive impact on patient satisfaction results as measured by PG surveys. METHODS : This is a retrospective(More)
Infant products containing polyurethane foam are commonly treated with organophosphate flame retardants (PFRs), including tris(1,3-dichloro-2-propyl)phosphate (TDCIPP) and triphenyl phosphate (TPHP). Infants may have greater exposure due to greater contact with these products, yet little is known about levels of exposure or the factors contributing to(More)
OBJECTIVES The objective of this study was to describe the prevalence of pneumonia-like signs and symptoms in patients admitted from the emergency department (ED) with a diagnosis of community acquired pneumonia (CAP) but subsequently discharged from the hospital with a nonpneumonia diagnosis. METHODS A retrospective, structured, chart review of ED(More)
OBJECTIVES The value of unstructured physician estimate of risk for disease processes, other than acute coronary syndrome (ACS), has been demonstrated. The authors sought to evaluate the predictive value of unstructured physician estimate of risk for ACS in emergency department (ED) patients without obvious initial evidence of a cardiac event. METHODS(More)
Multidetector computed tomography (MDCT) imaging, a technological advance over traditional CT, is a promising possible alternative to cardiac catheterization for evaluating patients with chest pain in the emergency department (ED). In comparison with traditional CT, MDCT offers increased spatial and temporal resolution that allows reliable visualization of(More)
BACKGROUND Trends in the prevalence of acute myocardial infarction in sub-Saharan Africa have not been well described, despite growing recognition of the increasing burden of cardiovascular disease in low- and middle-income countries. The aim of this systematic review was to describe the prevalence of acute myocardial infarction in sub-Saharan Africa. (More)
OBJECTIVE The Thrombolysis in Myocardial Infarction (TIMI) score is a validated tool for risk stratification of acute coronary syndrome. We hypothesized that the TIMI risk score would be able to risk stratify patients in observation unit for acute coronary syndrome. METHODS STUDY DESIGN Retrospective cohort study of consecutive adult patients placed in(More)
BACKGROUND Point-of-care ultrasound has been suggested to improve outcomes from advanced cardiac life support (ACLS), but no large studies have explored how it should be incorporated into ACLS. Our aim was to determine whether cardiac activity on ultrasound during ACLS is associated with improved survival. METHODS We conducted a non-randomized,(More)
BACKGROUND Determining which patients presenting to the Emergency Department (ED) require further work-up for acute coronary syndrome (ACS) can be difficult. The utility of routine observation for cardiac testing in low-risk young adult patients has been questioned. STUDY OBJECTIVES We investigated the rate of positive findings yielded by routine cardiac(More)
