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.

The 2013 ACCF/AHA guideline for the management of ST elevation myocardial infarction (STEMI) recommends that patients be transported by emergency medical services (EMS) directly to a percutaneous coronary intervention (PCI)-capable hospital. We examined the effects of EMS use according to inter-hospital transfer on time to PCI in STEMI patients. ⋯ EMS use significantly increased the odds of timely primary PCI to patients directly transported to a primary PCI center, but not in patients transferred from another hospital. EMS systems that identify STEMI patients and transport them to PCI capable hospitals, and processes to expedite the transfer of patients between non-PCI and PCI hospitals need to be developed further.

Impact of Building Height and Volume on Cardiac Arrest Response Time.
Emergency medical services (EMS) care may be delayed when out-of-hospital cardiac arrest (OHCA) occurs in tall or large buildings. We hypothesized that larger building height and volume were related to a longer curb-to-defibrillator activation interval. We retrospectively evaluated 3,065 EMS responses to OHCA in a large city between 2003-13 that occurred indoors, prior to EMS arrival, and without prior deployment of a defibrillator. ⋯ Both taller and larger-volume buildings had longer curb-to-AED intervals but shorter 911 call-to-curb arrival intervals. As a consequence, building height and volume had a modest overall relationship with interval from call to defibrillator application. These results do not support the hypothesis that either taller or larger-volume buildings need cause poorer outcomes in urban environments.

Naloxone administration is an important component of resuscitation attempts by emergency medical services (EMS) for opioid drug overdoses. However, EMS providers must first recognize the possibility of opioid overdose in clinical encounters. As part of a public health response to an outbreak of opioid overdoses in Rhode Island, we examined missed opportunities for naloxone administration and factors potentially influencing EMS providers' decision to administer naloxone. ⋯ Older individuals, particularly those over age 50, were more likely not to receive naloxone than victims younger than age 30 (OR 4.8; 95% CI 1.3-17.4; p-value 0.02). Women, older individuals, and those patients without clear signs of illicit drug abuse, were less likely to receive naloxone in EMS resuscitation attempts. Heightened clinical suspicion for opioid overdose is important given the recent increase in overdoses among patients due to prescription opioids.

Emergent and Urgent Transfers to Neurosurgical Centers in Ontario.
Critically ill neurosurgical patients require expedient access to neurosurgical centers (NC) to improve outcome. In regionalized health systems patients are often initially evaluated at a non-neurosurgical center (NNC) and are subsequently transferred to a NC using air or ground vehicles. We sought to identify barriers to accessing a NC for critically ill patients by analyzing interfacility transfer times and referral patterns in the province of Ontario. ⋯ Regionalization of neurosurgical services in Ontario has led to heavy reliance upon patient transfers to maintain continuity of care. Access to a NC varied across the province, which may represent regional differences in neurosurgical bed availability, resource limitations at smaller NCs, or environmental factors. Our descriptions of referral patterns and transport times can guide health system planning in Ontario and similar jurisdictions in the United States and Canada.
