Multicenter Study Comparative Study
Factors associated with emergency medical services scope of practice for acute cardiovascular events.
To examine prehospital emergency medical services (EMS) scope of practice for acute cardiovascular events and characteristics that may affect scope of practice; and to describe variations in EMS scope of practice for these events and the characteristics associated with that variability. ⋯ We noted statistically significant variations in scope of practice by rural vs. urban setting, medical director involvement, and type of EMS service (fire department-based/non-fire department-based; volunteer/paid). These variations highlight local differences in the composition and capacity of EMS providers and offer important information for the transition towards the implementation of a national scope of practice model.

Randomized Controlled Trial Comparative Study
Paramedic King Laryngeal Tube airway insertion versus endotracheal intubation in simulated pediatric respiratory arrest.
Pediatric endotracheal intubation (ETI) is difficult and can have serious adverse events when performed by paramedics in the prehospital setting. Paramedics may use the King Laryngeal Tube airway (KLT) in difficult adult airways, but only limited data describe their application in pediatric patients. ⋯ Paramedics and paramedic students demonstrated similar airway insertion performance between KLT and ETI in simulated, pediatric respiratory arrest. Most subjects preferred KLT. KLT may provide a viable alternative to ETI in prehospital pediatric airway management.

Comparative Study
Interevaluator reliability of a mock paramedic practical examination.
Prior to graduation, paramedic students must be assessed for terminal competency and preparedness for national credentialing examinations. Although the procedures for determining competency vary, many academic programs use a practical and/or oral examination, often scored using skill sheets, for evaluating psychomotor skills. However, even with validated testing instruments, the interevaluator reliability of this process is unknown. Objective. We sought to estimate the interevaluator reliability of a subset of paramedic skills as commonly applied in terminal competency testing. ⋯ There was high variability and low reliability among qualified evaluators using skill sheets as a scoring tool in the evaluation of a mock terminal competency assessment. Further research is needed to determine the true overall interevaluator reliability of this commonly used approach, as well as the ideal number, training, and characteristics of prospective evaluators.

Comparative Study
Variables associated with successful intubation attempts using video laryngoscopy: a preliminary report in a helicopter emergency medical service.
Multiple studies have demonstrated varying rates of successful endotracheal intubation (ETI). Until the application of video laryngoscopy, little information regarding prehospital intubation could be analyzed objectively by individuals other than the provider performing the ETI. ⋯ Video laryngoscopy can measure multiple components of ETI performance. Successful ETI attempts have significantly shorter entry-to-POGO times and entry-to-tube times, obtain better views of the glottic opening (POGO and C-L view), and have a lower incidence of recognized esophageal intubation.

Comparative Study
Impact of an emergency department closure on the local emergency medical services system.
On July 12, 2010, Boston Medical Center (BMC), the busiest emergency department (ED) in Massachusetts, with more than 100,000 adult patient visits per year, consolidated its two fully functional EDs into one. In preparation for this consolidation, BMC implemented systems changes to mitigate potential negative effects on both BMC and emergency medical services (EMS) providers, including Boston Emergency Medical Services (Boston EMS), the provider of 9-1-1 EMS to the City of Boston. ⋯ The closure of one ED resulted in a statistically significant increase in turnaround intervals and a significant decrease in ED volume independent of EMS volumes. In the absence of ambulance diversion, ratios of EMS turnaround intervals and EMS volumes according to hospital destination can be used as alternatives to ambulance diversion times to examine the effects of system-level changes such as closure of an ED on an urban EMS system.
