Multicenter Study Observational Study
Lights and Siren Transport and the Need for Hospital Intervention in Trauma Patients.
Emergent ambulance transportation is associated with increased risk of collision, injury, and death for EMS professionals, patients, and the general public. Time saved using lights and siren (L&S) is typically small, and often provides minimal clinical benefit. Our objective was to investigate the frequency of L&S transports, describe the precision of the decision to employ L&S to predict the need for a time critical hospital intervention (TCHI) within 15 minutes of hospital arrival, identify clinical predictors of a TCHI, and compare clinical outcomes in patients transported by Emergency Medical Services (EMS) with and without L&S in a trauma-specific population. ⋯ Among patients that received a TCHI, over a third that were transported with L&S (36.8%) expired, compared with two of 14 patients (14.3%) not transported L&S. EMS professionals in this study demonstrated a high ability to discern which trauma patients did not require L&S. Nevertheless, L&S transport resulted in a TCHI less than one quarter of the time, suggesting an opportunity for further reduction of L&S transports in trauma patients.

Multiple national organizations have recommended and supported a national investment to increase the scientific evidence available to guide patient care delivered by Emergency Medical Services (EMS) and incorporate that evidence directly into EMS systems. Ongoing efforts seek to develop, implement, and evaluate prehospital evidence-based guidelines (EBGs) using the National Model Process created by a multidisciplinary panel of experts convened by the Federal Interagency Committee on EMS (FICEMS) and the National EMS Advisory Council (NEMSAC). Yet, these and other EBG efforts have occurred in relative isolation, with limited direct collaboration between national projects, and have experienced challenges in implementation of individual guidelines. ⋯ Other action items include promoting research that supports creation and evaluates the impact of EBGs, promoting the development of new EBGs through improved stakeholder collaboration, and improving education on evidence-based medicine for all prehospital providers. The Strategy intends to facilitate implementation of EBGs by improving guideline dissemination and incorporation into protocols, and seeks to establish standardized evaluation methods for prehospital EBGs. Finally, the Strategy proposes that key stakeholder organizations financially support the Prehospital Guidelines Consortium as a means of implementing the Strategy, while together promoting additional funding for continued EBG efforts.

Observational Study
Accuracy of Prehospital Intravenous Fluid Volume Measurement by Emergency Medical Services.
Prehospital treatment protocols call for intravenous (IV) fluid for patients with shock, yet the measurement accuracy of administered fluid volume is unknown. The purpose of the current study was to assess the accuracy of documented and self-reported fluid volumes administered to medical patients by paramedics during prehospital care. We conducted a pilot, observational study nested within a parent cohort study of prehospital biomarkers in a single EMS agency transporting patients to a tertiary care hospital in Pittsburgh, Pennsylvania over 8 months. Among eligible nontrauma, noncardiac arrest patients, we studied the self-reported IV fluid volume on ED arrival by paramedics, documented fluid volume in the EMS record, and compared those to the mass-derived fluid volume. We quantified the absolute error between methods, and determined EMS transport times or initial prehospital systolic blood pressure had any effect on error. We enrolled 50 patients who received prehospital IV fluid and had mass-derived fluid volume measured at ED arrival. Of these, 21 (42%) patients had IV fluid volume subsequently documented in EMS records. The median mass-derived fluid volume was 393 mL [IQR: 264-618 mL]. Mass-derived volume was similar for subjects who did (386 mL, IQR: 271-642 mL) or did not (399 mL, IQR: 253-602) have documented fluid administration (p > 0.05). The median self-reported fluid volume was 250 mL [IQR: 150-500 mL] and did not differ by documentation (p > 0.05). The median absolute error comparing self-reported to mass-derived fluid volume was 109 mL [IQR: 41-205 mL], and less than 250 mL in more than 80% of subjects. The median absolute error comparing documented fluid to mass-derived fluid volume was 142 mL [IQR: 64-265 mL], and was less than 250 mL in 71% of subjects. No difference in absolute error for either self-reported or document fluid volumes were modified by transport time or prehospital systolic blood pressure. Prehospital IV fluid administration is variably documented by EMS, and when recorded is typically within 250 mL of mass-derived fluid volume. ⋯ emergency medical services; prehospital resuscitation; intravenous fluids; fluids.

Anaphylaxis in the pediatric population is both serious and potentially lethal. The incidence of allergic and anaphylactic reactions has been increasing and the need for life saving intervention with epinephrine must remain an important part of Emergency Medical Services (EMS) provider training. Our aim was to characterize dosing and timing of epinephrine, diphenhydramine, and albuterol in the pediatric patient with anaphylaxis. ⋯ Among the patients in anaphylaxis not given epinephrine prior to EMS arrival, 6 (12%; 95% CI 3%, 21%) received epinephrine from EMS, 10 (20%; 95% CI 9%, 30%) received diphenhydramine only, 9 (18%, 95% CI 7%-28%) received only albuterol and 17 (33%, 95% CI 20%-46%) received both albuterol and diphenhydramine. 9 patients in anaphylaxis received no treatment prior to arriving to the emergency department (18%, 95% CI 7%-28%). In pediatric patients who met criteria for anaphylaxis and the use of epinephrine, only 54% received epinephrine and the overwhelming majority received it prior to EMS arrival. EMS personnel may not be treating anaphylaxis appropriately with epinephrine.
