Introduction: Uncontrolled bleeding is a preventable cause of death in rural trauma. Herein, we examined the appropriateness, effectiveness, and safety of tourniquet application for bleeding control in a rural trauma system. Methods: Medical records of adult patients admitted to our academic Level I trauma center between July 2015 and December 2018 were retrospectively reviewed. ⋯ Conclusion: Even with long transport times, early tourniquet application for hemorrhage control in rural settings is safe with no significant attributable morbidity and mortality compared to published studies on urban civilian tourniquet use. The observed rates of non-indicated and ineffective tourniquets indicate suboptimal tourniquet usage and application. Opportunity exists for standardized hemorrhage control training on the use of direct pressure and pressure dressings, indications for tourniquet use, and effective tourniquet application.

Objective: Many emergency medical services (EMS) protocols for out-of-hospital cardiac arrests (OHCA) include point-of-care (POC) glucose measurement and administration of dextrose, despite limited knowledge of benefit. The objective of this study was to describe the incidence of hypoglycemia and dextrose administration by EMS in OHCA and subsequent patient outcomes. Methods: This was a retrospective analysis of OHCA in a large, regional EMS system from 2011 to 2017. ⋯ Of the 32,780 patients with a documented POC glucose result who were identified as hypoglycemic, only 27 (0.08%) received field treatment, and survived to discharge with good neurologic outcome. 48 (6%) of patients in the treatment group had SHD vs. 72 (8%) without treatment, risk difference -2.0% (95%CI -4.4%, 0.4%), p = 0.1. Conclusion: In this EMS system, POC glucose testing was common in adult OHCA, yet survival to hospital discharge with good neurologic outcome did not differ between patients treated and untreated for hypoglycemia. These results question the common practice of measuring and treating hypoglycemia in OHCA patients.

Background: Patients presenting with a diagnosis of ruptured abdominal aortic aneurysm (RAAA) to community hospitals must be transported to tertiary care centers, where necessary resources are available. Unfortunately, guidelines for treatment of RAAA lack high-level evidence on the optimal resuscitation of RAAA patients during transport. We hypothesized that transfusion of packed red blood cells (PRBCs) during transport would not delay transport times in patients with RAAA. ⋯ Mean ± standard deviation (SD) of the total intervals were 67 ± 28 and 71 ± 42 minutes, among patients who received or did not receive PRBCs in transit respectively, with no significant difference (p = 0.437). Following adjusted analysis, the receipt of PRBCs during transport was not associated with increased transport times, after accounting for age, hypotension, endovascular aneurysm repair (EVAR), and PRBC transfusion at the OSH. Conclusion: PRBC transfusion during air medical transport in patients with RAAA did not delay transport times.

Objective: Few areas of prehospital care are supported by evidence-based guidelines (EBGs). We aimed to identify gaps in clinical and operational prehospital EBGs to prioritize future EBG development and research funding. Methods: Using modified Delphi methodology, we sought consensus among experts in prehospital care and EBG development. ⋯ The final prioritized list of clinical EBG gaps was: 1) airway management in adult and pediatric patients, 2) care of the pediatric patient, and 3) management of prehospital behavioral health emergencies, with 79% of participants agreeing. The final prioritized list of operational EBG gaps was: 1) define and measure the impact of EMS care on patient outcomes, 2) practitioner wellness, and 3) practitioner safety in the out-of-hospital environment, with 86% of participants agreeing. Conclusions: This modified Delphi study identifies gaps in prehospital EBGs that, if prioritized for development and research funding, would be expected to have the greatest impact on prehospital clinical care and operations.

Objective: U. S. opioid overdoses increased nearly sixfold from 1999 to 2018, and greater than 1% of all emergency medical services (EMS) encounters now involve naloxone administration. While "treat and release" protocols may have low short-term mortality, the risk of subsequent non-fatal overdoses is not known. ⋯ Refusal of transport was associated with a hazard ratio of 1.66 (95% CI: 1.23-2.23) for subsequent EMS encounters with naloxone administration. Conclusions: Non-transport after prehospital naloxone administration is associated with an increased risk of subsequent non-fatal overdose requiring EMS intervention. Limitations include the use of a single EMS agency as patients may have had uncaptured overdose encounters in neighboring municipalities.
