Evaluation of Use of Epinephrine and Time to First Dose and Outcomes in Pediatric Patients With Out-of-Hospital Cardiac Arrest.

Importance: While epinephrine has been widely used in prehospital resuscitation for pediatric patients with out-of-hospital cardiac arrest (OHCA), the benefit and optimal timing of epinephrine administration have not been fully investigated.

Objectives: To evaluate the association between epinephrine administration and patient outcomes and to ascertain whether the timing of epinephrine administration was associated with patient outcomes after pediatric OHCA.

Design, Setting, And Participants: This cohort study included pediatric patients (<18 years) with OHCA treated by emergency medical services (EMS) from April 2011 to June 2015.

Identifying Predictors of Undertriage in Injured Older Adults After Implementation of Statewide Geriatric Trauma Triage Criteria.

Objectives: The objective was to identify factors associated with transport of injured older adults meeting statewide geriatric trauma triage criteria to a trauma center.

Methods: An observational retrospective cohort study using the 2009 to 2011 Ohio Trauma Registry. Subjects were adults ≥ 70 years old who met Ohio's geriatric triage criteria for trauma center transport by emergency medical services.
