Multicenter Study Observational Study
QTc prolongation as a marker of 30-day serious outcomes in older patients with syncope presenting to the Emergency Department.
Syncope is a common chief complaint in the ED, and the electrocardiogram (ECG) is a routine diagnostic tool in the evaluation of syncope. We assessed whether increasingly prolonged QTc intervals are associated with composite 30-day serious outcomes in older adults presenting to the ED with syncope. ⋯ In a cohort of older patients presenting with syncope, increased QTc interval was a marker of but was not independently predictive of composite 30-day serious outcomes.

Multicenter Study
Clinical differences between visits to adult freestanding and hospital-based emergency departments.
Compare clinical characteristics for adult visits to freestanding emergency departments (FEDs) and a hospital-based ED (HBED). ⋯ Differences were observed in clinical characteristics of adult HBED visits versus FEDs. Results of this study can help communities plan their emergency care system.

Prognostic factors for patients with accidental hypothermia: A multi-institutional retrospective cohort study.
In cases of severe accidental hypothermia (AH) in urban areas, the prognostic factors are unknown. We identified factors associated with in-hospital mortality in patients with moderate-to-severe AH in urban areas of Japan. ⋯ The independent prognostic factors associated with in-hospital mortality of patients with moderate-to-severe AH in urban areas of Japan were age ≥ 75 years, need for assistance with ADL, hemodynamic instability, and hyperkalemia.

Relative tachycardia is associated with poor outcomes in post-cardiac arrest patients regardless of therapeutic hypothermia.
To investigate whether the relationship between heart rate and neurological outcome is independent of therapeutic hypothermia (TH) and whether heart rate is related to hemodynamic instability post-cardiac arrest. ⋯ Relative tachycardia is associated with poor neurological outcomes in post-cardiac arrest patients, independent of TH, and with higher serum lactate levels and admission SOFA scores.
