Observational Study
Cerebral oximetry during out-of-hospital resuscitation: Pilot Study of First Responder Implementation.
Background: Anoxic brain injury is a common mode of death following out-of-hospital cardiac arrest (OHCA). We assessed the course of regional cerebral oxygen saturation (rSO2) at the outset and during first responder resuscitation to understand its relationship with return of spontaneous circulation (ROSC) and functional survival. Methods: We undertook a prospective observational investigation of adult OHCA patients treated by a first-responder EMS agency in King County, WA. ⋯ Among patients who achieved ROSC, those who would survive with CPC 1-2 had a higher rSO2 cerebral oximetry following ROSC than nonsurvivors (74% vs. 60%, p = 0.04 at 5 minutes post ROSC), a difference that was not evident in the minutes prior to ROSC (55% vs. 51% at 3 minutes prior to ROSC, p = 0.5). Conclusion: In this observational study, where first responders applied cerebral oximetry, higher rSO2 during the course of care predicted ROSC among all patients and predicted favorable survival among those who achieved ROSC. Future investigation should evaluate whether and how treatments might modify rSO2 and in turn may influence prognosis.

Study Objective: Most 911 calls result in ambulance transport to an emergency department. In some cases, transport is refused or deemed unnecessary. The frequency of pediatric non-transport is unknown. ⋯ Conclusion: Almost one-third of pediatric 911 activations result in non-transport. Although very few children have been included in pilots of alternate transport processes to date, non-transport is actually more common in children than adults. More work is needed to understand better the patient safety and economic implications of this practice.

Observational Study
Impact of Trauma Center Designation Level on the Survival of Trauma Patients Transported by Police in the United States.
Background: Police involvement in trauma management and transport is increasing in the US. Little is known about prehospital triage criteria and transport patterns used by Police Officers. In this study, we examined the impact of trauma designation level on the survival of trauma patients transported to trauma centers by police. ⋯ Conclusion: Transport of trauma patients by police to trauma centers of different designation levels was not associated with survival in this study. Survival was also similar to other trauma studies. As such, trauma patients may be safely transported by Police to closest trauma designated center without affecting outcomes.

Background: Research networks need access to EMS data to conduct pilot studies and determine feasibility of prospective studies. Combining data across EMS agencies is complicated and costly. Leveraging the National EMS Information System (NEMSIS) to extract select agencies' data may be an efficient and cost-effective method of providing network-level data. ⋯ PECARN's EMS data were similar to the national data, though racial/ethnic minorities and some primary impressions may be under-represented. Additionally, more EMS activations in PECARN study areas originated through 9-1-1 but fewer were transported by the documenting agency. This is likely related to the type of participating agencies, their ALS response level, and the diversity of the communities they serve.

Background: Prehospital pediatric drug dosing errors occur at a high rate. Multiple factors contribute to these errors. The contribution of weight estimation errors to drug dosing errors is unknown. ⋯ Conclusions: BLT is the most frequently used method to obtain a patient weight. Drug dosing errors were most frequent with patient age, followed by BLT and asking the parent. System-based solutions-weight determination hierarchy, not using the BLT on seated patients, and more frequent training and practice with the BLT-are needed to improve drug-dosing accuracy.
