Multicenter Study
Availability and quality of computed tomography and magnetic resonance imaging equipment in U.S. emergency departments.
The objective was to determine the availability and quality of computed tomography (CT) and magnetic resonance imaging (MRI) equipment in U.S. emergency departments (EDs). The authors hypothesized that smaller, rural EDs have less availability and lower-quality equipment. ⋯ Although access to CT imaging was high (>90%), CT resolution and access to MRI were variable. Based on observed differences, the availability and quality of imaging equipment may vary by ED size and location.

The objectives were to compare the proportion of false-positive activations and intervention times between emergency department (ED) and field-based activation of the coronary catheterization laboratory (cath) team for emergency medical services (EMS) patients identified by out-of-hospital (OOH) 12-lead electrocardiogram (ECG) with ST-segment elevation myocardial infarction (STEMI). ⋯ Emergency physician activation of the cath team results in a lower proportion of false-positive activations without clearly sacrificing DTB time when compared to field activation based solely on the results of the OOH ECG.

Review Comparative Study
Intraarticular lidocaine versus intravenous procedural sedation with narcotics and benzodiazepines for reduction of the dislocated shoulder: a systematic review.
Anterior shoulder dislocations commonly present to the emergency department (ED). The time associated with procedural sedation for the reduction of anterior shoulder dislocations can be lengthy and may require use of additional personnel. Complications associated with intravenous (IV) medications for procedural sedation are well documented. ⋯ The use of IAL for reduction of anterior shoulder dislocations should be strongly considered as a first line therapy because it is effective and safe and may potentially reduce time spent in the ED.

Multicenter Study
Relapse after emergency department discharge for acute asthma.
The objectives were to determine patient and treatment-response factors associated with relapse after emergency department (ED) treatment for acute asthma. ⋯ Ethnicity (white), female gender, prior ED visits and admissions for asthma, and recent treatments (especially oral CS) were associated with asthma relapse, which remains relatively common. Future research is required to target this high-risk group.
