Introduction: Multiple national organizations have identified a need to incorporate more evidence-based medicine in emergency medical services (EMS) through the creation of evidence-based guidelines (EBGs). Tools like the Appraisal of Guidelines for Research and Evaluation (AGREE) II and criteria outlined by the National Academy of Medicine (NAM) have established concrete recommendations for the development of high-quality guidelines. While many guidelines have been created that address topics within EMS medicine, neither the quantity nor quality of prehospital EBGs have been previously reported. ⋯ Conclusions: EBGs exist addressing a variety of topics in EMS medicine. This systematic review and appraisal of EMS guidelines identified a wide range in the quality of these guidelines and variable reporting of key elements of clinical guidelines. Future guideline developers should consider established methodological and reporting recommendations to improve the quality of EMS guidelines.

The opioid crisis is a growing cause of mortality in the United States and may be mitigated by innovative approaches to identifying individuals at-risk of fatal opioid overdose. We examined Emergency Medical Services (EMS) utilization among a cohort of individuals who died from opioid overdose in order to identify potential opportunities for intervention. Methods: Individuals who died of unintentional opioid overdose in a large North Carolina county between 01/01/2014 and 12/31/2016 were studied in a retrospective cohort. ⋯ Drug or alcohol use was documented by EMS in 33% of all encounters and an opioid prescription was reported in 22% of encounters. Conclusions: Nearly one-third of individuals who died from accidental opioid overdose utilized EMS in the year before their death and nearly one-fifth had a drug-related encounter. EMS encounters may present an opportunity to identify individuals at-risk of opioid overdose and, ultimately, reduce overdose mortality.

Case Reports
Tension Hemopneumothorax in the Setting of Mechanical CPR during Prehospital Cardiac Arrest.
There are several complications associated with automated mechanical CPR (AM-CPR), including tension pneumothoraces. The incidence of these complications and the risk factors for their development remain poorly characterized. Tension hemopneumothorax is a previously unreported complication of AM-CPR. ⋯ Discussion/Conclusion: Migration of AM-CPR device pistons may contribute to the development of iatrogenic injuries such as hemopneumothoraces. Patients with underlying lung disease may be at a higher risk of developing pneumothoraces or hemopneumothoraces during the course of AM-CPR. Awareness of these potential complications may aid first responders by improving vigilance of piston location and by providing quicker recognition of iatrogenic injuries that need immediate attention to improve the opportunity for ROSC.

In out-of-hospital cardiac arrest (OHCA), 10-50% of patients have return of spontaneous circulation (ROSC) before hospital arrival. It is important to investigate the relation between time-to-ROSC and survival to determine the optimal timing of transport to the hospital in patients without ROSC. Methods: We analyzed data of OHCA patients with a presumed cardiac cause (excluding traumatic and other obvious non-cardiac causes) and ROSC before hospital arrival from the Amsterdam Resuscitation Study (ARREST) database. ⋯ Conclusion: In OHCA patients with prehospital ROSC survival significantly decreases with increasing time-to-ROSC. Of all patients, 90% of survivors had achieved ROSC within the first 15 min of EMS resuscitation. The optimal time for the decision to transport is between 8 and 15 min after EMS arrival.

The chaotic and complex nature of delivering patient care in the prehospital setting complicates the provision of real-time formative feedback to paramedic students. Although the use of simulations is widespread in emergency medical services (EMS) education, a high degree of variability precludes consistent performance assessment in EMS. Objectives: The objective of this study was to define and validate key domains required to evaluate paramedic prehospital performance. ⋯ The first round of the Delphi process generated 64 content domains, which were reduced to nine unique content domains via thematic analysis. These nine content domains fit well within the broader domains identified by the focus groups with one specific area, critical thinking and reasoning, being listed in two key areas based on the definitions of the focus group domains of patient assessment and patient management. Conclusion: The content domains identified in this study provide EMS educators a theoretical framework for designing the performance assessment of newly trained professionals in the prehospital setting.
