Objectives: The objective was to compare the survival outcomes of emergency medical services (EMS)-witnessed to bystander-witnessed, and unwitnessed out-of-hospital cardiac arrests (OHCA) in Singapore. Secondary aims are to describe the 5-year trend in survival rates of EMS-witnessed arrests. Methods: This was a retrospective analysis of the Singapore's OHCA registry data from 2011 to 2015. ⋯ Conclusions: EMS-witnessed OHCAs were more likely to have favorable outcomes compared to bystander-witnessed and unwitnessed OHCAs. High PEA rates in EMS-witnessed arrests were associated with older patients with underlying preexisting medical conditions. Increasing public awareness on recognition of prodromal symptoms and early activation of EMS could improve post-arrest survival and neurological outcomes of OHCA.

Anaphylaxis is a life-threatening condition with a known effective prehospital intervention: parenteral epinephrine. The National Association of EMS Physicians (NAEMSP) advocates for emergency medical services (EMS) providers to be allowed to carry and administer epinephrine. ⋯ This literature review and consensus report describes the extant literature and the practical and policy issues related to non-EAI administration of epinephrine for anaphylaxis, and serves as a supplementary resource document for the revised NAEMSP position statement on the use of epinephrine in the out-of-hospital treatment of anaphylaxis, complementing (but not replacing) prior resource documents. The report concludes that there is some evidence that intramuscular injection of epinephrine drawn up from a vial or ampule by appropriately trained EMS providers-without limitation to specific certification levels-is safe, facilitates timely treatment of patients, and reduces costs.

Randomized Controlled Trial
Layperson Ability and Willingness to Use Hemostatic Dressings: A Randomized, Controlled Trial.
Background: The Hartford Consensus and Stop the Bleed Campaign empower the public to stop bleeding. While evidence for civilian tourniquet use is mounting, there is limited evidence regarding the public's ability to use hemostatic dressings. This study seeks to determine if laypeople can apply hemostatic dressings, and which hemostatic dressing they can use most successfully. ⋯ Educators and planners should consider including injectable sponges in their Stop the Bleed programs and products. Level of Evidence: II (RCT with significant difference. One negative criterion for observer blinding).

Objective: Pediatric care is now concentrated in urban specialty centers ("regionalization"), even for common conditions such as asthma. At the same time, rural emergency medical services (EMS) faces challenges related to adequate workforce staffing and financing. This statewide study describes how regionalization of pediatric inpatient care for asthma exacerbations affects EMS operations, particularly for rural agencies. ⋯ Conclusions: In this statewide study in Florida, we found long average estimated EMS travel distances to admitting facilities for Florida's pediatric population in rural counties for pediatric asthma exacerbations. Those long distances have great implications for rural EMS operations, including pediatric destination decisions, transport times, and availability for others who call 9-1-1. Further research on bypass and secondary transport rates, and outcomes for asthma and other pediatric conditions are required to further characterize pediatric regionalization's impact on rural EMS.

The opioid crisis is a growing concern for Americans, and it has become the leading cause of injury-related death in the United States. An adjunct to respiratory support that can reduce this high mortality rate is the administration of naloxone by Emergency Medical Services (EMS) practitioners for patients with suspected opioid overdose. However, clear evidence-based guidelines to direct EMS use of naloxone for opioid overdose have not been developed. ⋯ Where we are unable to make recommendations due to evidence limitations (dosing, titration, timing, and transport) we offer technical remarks. Limitations of our work include the introduction of novel synthetic opioids after many of the reviewed papers were produced, which may affect the dose of naloxone required for effect, high risk of bias and imprecision in the reviewed papers, and the introduction of new naloxone administration devices since many of the reviewed papers were published. Future research should be conducted to evaluate new devices and address the introduction of synthetic opioids.
