Objective: Our objective was to examine the appropriateness of cardiac troponin (cTn) testing among patients with cTn increases.
Methods: This is a planned secondary analysis of the Use of TROPonin In Acute coronary syndromes (UTROPIA, NCT02060760) observational cohort study. Appropriateness of cTn testing was adjudicated for emergency department patients with cTn increases >99 percentile and analyzed using both contemporary and high-sensitivity (hs) cTnI assays according to sub-specialty, diagnoses, and symptoms.
Introduction: Complications associated with the emergency department (ED) management of hyperkalemia are not well characterized. The goals of this study were to describe the frequency of hypoglycemia following the use of insulin to shift potassium intracellularly and to examine the association of key variables with this complication.
Methods: Adult ED patients (≥18 years old) with hyperkalemia (>5.
Background: Studies addressing patients with type 2 myocardial infarction and myocardial injury, including the impact of using high-sensitivity (hs) cardiac troponin (cTn) assays on their incidence are needed.
Methods: Ours is a prospective, observational US cohort study. Consecutive emergency department patients with serial cTnI measurements were studied.
Background: We examined the diagnostic performance of high-sensitivity cardiac troponin I (hs-cTnI) vs contemporary cTnI with use of the 99th percentile alone and with a normal electrocardiogram (ECG) to rule out acute myocardial infarction (MI) and serial changes (deltas) to rule in MI.
Methods: We included consecutive patients presenting to a US emergency department with serial cTnI onclinical indication. Diagnostic performance for acute MI, including MI subtypes, and 30-day outcomes were examined.
Background: International Classification of Diseases (ICD) coding is the standard diagnostic tool for healthcare management. At present, type 2 myocardial infarction (T2MI) classification by the Universal Definition of Myocardial Infarction (MI) remains ignored in the ICD system. We determined the concordance for the diagnosis of MI using ICD-9 coding vs the Universal Definition.

Design: Single center, prospective observational cohort study of consecutive patients with out-of-hospital cardiopulmonary arrests.
Setting: Academic tertiary care hospital and level one trauma center in Minneapolis, MN.
Study Objective: We describe the current state of emergency department to inpatient handoffs and assess handoff best practices between emergency physicians and hospitalist medicine physicians.
Methods: A survey was distributed electronically to emergency medicine and internal medicine physicians at 10 hospitals across the United States. Descriptive and quantitative analysis was performed on survey results.
Objective: To determine the most accurate predictor of central venous pressure among three point-of-care venous ultrasound techniques.
Design: Cross-sectional study.
Setting: Medical ICU in an academic medical center.
