ObjectiveTimely administration of epinephrine is critical in the treatment of anaphylaxis. This study sought to determine the frequency of administration of epinephrine by EMS providers caring for pediatric patients in the prehospital setting.MethodsWe examined data from the NC EMS database (PreMIS) from 2010-3 to determine frequency of epinephrine administration in pediatric patients with anaphylaxis. We studied patients <18 years of age with an EMS provider impression of "allergic reaction." Anaphylaxis was present if there was hypotension (defined as SBP < 90 or DBP < 45 for patients age 11 and older, and SBP < 70 + (2 × age) for patients ages 0-10), or impaired respirations (defined as description of labored or absent respirations, or RR < 12 or > 30). We determined the overall frequency of epinephrine administration. A multivariate logistic regression was then constructed to examine the impact of the following variables on appropriate epinephrine administration: age < 10, non-white race, rural county of case origin, duration of transportation from scene, and presence of a paramedic.ResultsA total of 504 patients met inclusion criteria, of which 471 demonstrated anaphylaxis as previously defined. A total of 153 patients with anaphylaxis received epinephrine (32.4%, 95% CI 28.3-36.9%). Age < 10 was associated with increased odds of not receiving epinephrine appropriately (OR 2.90, 95% CI 1.85-4.54, p < 0.001). Other variables did not have statistically significant impact on epinephrine administration.ConclusionThere are missed opportunities for prehospital administration of epinephrine in pediatric patients with anaphylaxis. Very young children (age < 10) had increased odds for not receiving epinephrine.
