OBJECTIVE: Return visits to the emergency department (RTED) for the same clinical complaint occur in 2.7% to 8.1% of children presenting to pediatric emergency departments (PEDs). Most studies examining RTEDs have focused solely on PEDs and do not capture children returning to other local emergency departments (EDs). Our objective was to measure the frequency and characterize the directional pattern of RTED to any of 18 EDs serving a large geographic area for children initially evaluated at a PED...

OBJECTIVES: Emergency medical services (EMS) prenotifications are critical, although they oftentimes inaccurately convey the arriving patient's true acuity, resulting in inappropriate preparation in the emergency department. The objectives of this study were (1) to determine interrater reliability of acuity prediction based on prenotifications among physicians and (2) to compare predicted versus actual patient acuity based on prenotifications. METHODS: A panel of physicians reviewed recordings of EMS prenotifications and then predicted the patient's acuity using the Emergency Severity Index (ESI)...

BACKGROUND: Most patients with acute heart failure (AHF) admitted to critical care units (CCUs) are low acuity and do not require CCU-specific therapies, suggesting that they could be managed in a lower-cost ward environment. This study identified the predictors of clinical events and the need for CCU-specific therapies in patients with AHF. METHODS: Model derivation was performed using data from patients in the ASCEND-HF trial cohort (n=7,141), and the Acute Heart Failure Emergency Management community-based registry (n=666) was used to externally validate the model and to test the incremental prognostic utility of 4 variables (heart failure etiology, troponin, B-type natriuretic peptide [BNP], ejection fraction) using net reclassification index and integrated discrimination improvement...
