Multicenter Study
Access to Federally Qualified Health Centers and Emergency Department Use Among Uninsured and Medicaid-insured Adults: California, 2005 to 2013.
While improved access to safety net primary care providers, like federally qualified health centers (FQHCs), is often cited as a route to alleviate potentially preventable emergency department (ED) visits, no studies have longitudinally established the impact of improving access to FQHCs on ED use among Medicaid-insured and uninsured adults. We aimed to determine whether improved access to FQHCs was associated with lower ED use by uninsured and Medicaid-insured adults. ⋯ We were unable to detect a consistent association between our measures of FQHC access and ED use by Medicaid-insured and uninsured nonelderly California adults, underscoring the importance of investigating additional drivers to reduce ED use among these vulnerable patient populations.

Multicenter Study
Discriminatory Value of the Ascending Aorta Diameter in Suspected Acute Type A Aortic Dissection.
The objective was to determine if ascending aorta (AscAo) diameters measured by noncontrast computed tomography (CT) allow for meaningful discrimination between patients with and without type A aortic dissection (TAAD), ideally with 100% sensitivity. ⋯ Nearly all patients with TAAD appear to have enlarged AscAo diameters as measured by noncontrast CT, whereas most patients with suspected but absent TAAD have relatively normal AscAo diameters. Both raw and normalized AscAo measures provided relatively comparable discriminatory value. If validated, these data may be useful in adjudicating risk among patients with suspected TAAD in whom a criterion standard test is unavailable, nondiagnostic, or contraindicated.

Review Meta Analysis
Prognostic Accuracy of the HEART Score for Prediction of Major Adverse Cardiac Events in Patients Presenting with Chest Pain - A Systematic Review and Meta-Analysis.
The HEART score has been proposed for emergency department (ED) prediction of major adverse cardiac events (MACE). We sought to summarize all studies assessing the prognostic accuracy of the HEART score for prediction of MACE in adult ED patients presenting with chest pain. ⋯ The HEART score has excellent performance for prediction of MACE (particularly mortality and MI) in chest pain patients and should be the primary clinical decision instrument used for the risk stratification of this patient population.

Randomized Controlled Trial Multicenter Study
Low-dose Magnesium Sulfate Versus High Dose in the Early Management of Rapid Atrial Fibrillation: Randomized Controlled Double-blind Study (LOMAGHI Study).
We aim to determine the benefit of two different doses magnesium sulfate (MgSO4 ) compared to placebo in rate control of rapid atrial fibrillation (AF) managed in the emergency department (ED). ⋯ Intravenous MgSO4 appears to have a synergistic effect when combined with other AV nodal blockers resulting in improved rate control. Similar efficacy was observed with 4.5 and 9 g of MgSO4 but a dose of 9 g was associated with more side effects.
