Unassigned school epinephrine used more than assigned injectors

ORLANDO – At schools in a Texas district, unassigned epinephrine injectors were used more often than assigned ones were, according to results of an analysis.

In the 2015-2016 and 2016-2017 school years, epinephrine was administered to students 31 times at schools in the Austin Independent School District, which began to stock unassigned epinephrine in its schools after state legislators approved a law in 2015 allowing, but not requiring, school districts to do so. In 21 of those cases, or 68% of the time, it was the unassigned stockpile that was used, Kathryn Neupert, MD, said at the joint congress of the American Academy of Allergy, Asthma, and Immunology and the World Asthma Organization.

She drew attention to the finding that 22% of the time in the study, the epinephrine use involved the unassigned stock for children with no history of anaphylaxis or allergy.

“It kind of argues that, for those people that we don’t know have anaphylaxis to anything, it’s definitely important to have it available to them,” reported Dr. Neupert, a resident at the University of Texas, Austin.

In 45% of the cases, epinephrine was administered to children who had a known history of allergic reactions but, for whatever reason, did not have an epinephrine injector assigned to them.

Food was the most common trigger for use of epinephrine, accounting for 48% of the injections, with fragrance at 16%, insect stings at 10%, and exercise and overheating at 7%.

Dr. Neupert and her associates said the frequency with which epinephrine was administered after exposure to a fragrance – seen in about the same amount for unassigned and assigned epinephrine – might signal a need for greater education.

She emphasized the importance of follow-up after the use of unassigned injectors. If children get epinephrine that was unassigned and they have known allergies, “be sure that they subsequently get back in with their pediatrician or their allergist [and] that they’re getting their up-to-date epinephrine pens renewed,” she noted.

Carla Davis, MD, a pediatrician at Baylor College of Medicine, Houston, said she hopes more school districts adopt the stock epinephrine policy, despite barriers of cost and education. “I do think that it’s important for these schools to have these, because 20% of children will have their first episode of food allergic reaction – and in some of those cases it will be anaphylaxis – in schools.”

Dr. Neupert had no relevant financial disclosures.
