Background: Patients with acute illness who receive intravenous (IV) fluids prior to hospital arrival may have a lower in-hospital mortality. To better understand whether this is a direct treatment effect or epiphenomenon of downstream care, we tested the association between a prehospital fluid bolus and the change in inflammatory cytokines measured at prehospital and emergency department timepoints in a sample of non-trauma, non-cardiac arrest patients at risk for critical illness. Methods: In a prospective cohort study, we screened 4,013 non-trauma, non-cardiac arrest encounters transported by City of Pittsburgh Emergency Medical Services (EMS) to 2 hospitals from August 2013 to February 2014. ⋯ Prehospital IL-10 and TNF were similar in both groups (IL-10: 3.5 [IQR 2.2-25.6] vs. 3.0 [IQR 1.9-9.0]; TNF: 7.5 [IQR 6.4-10.4] vs. 6.9 [IQR 6.0-8.3]). After adjustment for demographics, illness severity, and prehospital transport time, we observed a relative decrease in IL-6 at hospital arrival in those receiving a prehospital fluid bolus (adjusted β = -10.0, 95% CI: -19.4, -0.6, p = 0.04), but we did not detect a significant change in IL-10 (p = 0.34) or TNF (p = 0.53). Conclusions: Among non-trauma, non-cardiac arrest patients at risk for critical illness, a prehospital IV fluid bolus was associated with a relative decrease in IL-6, but not IL-10 or TNF.

Observational Study
Push Dose Epinephrine Use in the Management of Hypotension During Critical Care Transport.
Introduction: Hypotension is a critical event during the transport of critically ill patients. Push dose vasopressor use, though widely adopted by anesthesiologists, has only recently found use in the field of emergency medicine and may have utility in the management of out-of-hospital hypotension. This study aimed to characterize the hemodynamic effects and adverse events that occur following push dose epinephrine (PDE) administration by critical care transport (CCT) providers to correct documented hypotension. ⋯ Conclusions: Push dose epinephrine may be an effective method of temporarily resolving hypotension during the CCT of critically ill patients. In the cases where PDE was administered, there was close adherence to the established protocol and adverse events were found to be rare directly following PDE administration. Further research is needed to validate these findings, establish optimal dosing, and evaluate use in non-CCT prehospital settings.

Objective: Critical shortages of generic injectable medications are an ongoing challenge for Emergency Medical Services (EMS) systems. Mitigation strategies have been proposed to address the issue, but a limited amount of data exists quantifying the scope of the problem or describing strategies being used to ensure access to essential medications for prehospital care. In this study, we sought to quantify specific medication shortages and to determine the most frequently employed mitigation strategies to maintain medication availability in a large, regional EMS system. ⋯ None of the provider agencies self-reported adverse events due to the shortages. Conclusions: Critical medication shortages remain a problem for many EMS systems. EMS medical directors need to implement multiple mitigation strategies to maintain supply of critical medications for prehospital patient care.

Background: Advance care planning documents, including Physician Orders for Life-Sustaining Treatment (POLST), are intended to guide care near end of life, particularly in emergency situations. Yet, research on POLST during emergency care is sparse. Methods: A total of 7,055 injured patients age ≥ 65 years were transported by 8 emergency medical services (EMS) agencies to 23 hospitals in Oregon. ⋯ Conclusions: Among injured older adults transported by ambulance in Oregon, one in 5 had an active POLST form at the time of 9-1-1 contact, the prevalence of which increased over the following year. Mortality differences by POLST status were evident at 30 days and large by one year. This information could help emergency, trauma, surgical, inpatient, and outpatient clinicians understand how to guide patients through acute injury episodes of care and post-injury follow up.

Survival Benefit of Treatment at or Transfer to a Tertiary Trauma Center among Injured Older Adults.
Objective: It is well established that seriously injured older adults are under-triaged to tertiary trauma centers. However, the survival benefit of tertiary trauma centers (TC) compared to a non-tertiary trauma centers (Non-TCs) remains unclear for this patient population. Using improved methodology and a larger sample, we hypothesized that there was a difference in hospital mortality between injured older adults treated at TCs and those treated at Non-TCs. ⋯ Conclusions: Our results suggest a survival benefit for injured older adults treated at TCs. This benefit was also observed for patients transferred from non-tertiary trauma centers. Further research should focus on identifying specific subgroups of patients who would especially benefit from this level of care to minimize trauma triage inefficiencies.
