Observational Study
Characteristics of nontrauma patients receiving prehospital blood transfusion with the same triggers as trauma patients: A retrospective observational cohort study.
Objective: While prehospital blood transfusion (PHBT) for trauma patients has been established in many services, the literature on PHBT use for nontrauma patients is limited. We aimed to describe and compare nontrauma and trauma patients receiving PHBT who had similar hemodynamic triggers. Methods: We analyzed 3.5 years of registry data from a single prehospital critical care unit. ⋯ On admission, the nontrauma patients had lower hemoglobin (median 95 [84-119] vs 124 [108-133], p < 0.0001), higher pH (median 7.40 [7.27-7.44] vs 7.30 [7.19-7.36], p = 0.0015) and lower plasma thromboplastin time (median 55 [45-81] vs 72 [58-86], p = 0.0261) than the trauma patients. Conclusions: We identified four nontrauma patient groups in need of PHBT, and the patients appeared to be seriously ill. Efficacy of prehospital transfusion in nontrauma patients should be evaluated futher in becoming studies.

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.

Case Reports
Beyond Extracorporeal Cardiopulmonary Resuscitation: Systems of Care Supporting Cardiac Arrest Patients.
Introduction: Out-of-hospital cardiac arrest (OHCA) is a major cause of death and disability in the United States. Cardiac arrest centers (CAC) are necessary for the management of these critically ill and complex post arrest patients due to their specialized services and provider expertise. We report the case of a patient with OHCA and the systems of care involved in his resuscitation and recovery. ⋯ Conclusion: Cardiac arrest centers may be capable of advanced interventions including ECPR. However, the systems of care offered by these centers is itself a lifesaving intervention. As this case highlights, despite not receiving the specified intervention (ECPR) the systems of care required to offer such a resource led to this favorable outcome.

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.
