Underprescription of Epinephrine Autoinjectors (AAIs) in English Schools: A cost-Benefit Analysis of Spare Device programs
Table of Contents
A significant number of english schoolchildren at risk of anaphylaxis lack access to life-saving epinephrine autoinjectors (AAIs), despite clear clinical guidelines. New analysis reveals potential cost savings from providing schools with ‘spare’ devices, challenging current prescribing practices.
The Anaphylaxis Risk in Schools: A Growing Concern
Anaphylaxis, a severe and potentially life-threatening allergic reaction, is a growing concern in schools. While relatively rare,the consequences can be devastating. Food allergies are the most common trigger, but reactions can also be caused by insect stings, latex, and medications. Crucially, approximately 1 in 10 anaphylactic episodes occur within the school environment. This statistic underscores the need for readily available treatment.
The primary treatment for anaphylaxis is an epinephrine autoinjector (AAI), often referred to by the brand name EpiPen. These devices deliver a measured dose of epinephrine, reversing the symptoms of anaphylaxis and buying crucial time for emergency medical assistance. Current guidelines from both UK and European medicines regulators reccommend that individuals at risk of anaphylaxis have two AAIs readily available at all times.This advice accounts for the possibility of a single dose being insufficient, device malfunction, or incorrect administration.
alarming Underprescription Rates: The Data
A recent analysis published in the Archives of Disease in Childhood reveals a concerning gap between clinical recommendations and actual practice. Researchers analyzed routinely collected primary care data from the Clinical Practice Research Datalink (CPRD) Aurum, a nationally representative database, focusing on children and young people (aged 5-18) diagnosed with a food allergy between 2008 and 2018. The findings are stark:
* Overall AAI Prescription: Less than half (44%) of schoolchildren with a diagnosed food allergy had been prescribed at least one AAI.
* Repeat Prescriptions: Onyl a third (34%) received repeat AAI prescriptions, ensuring ongoing access to the medication.
* Anaphylaxis History: Even among pupils who had already experienced anaphylaxis,prescription rates were only 59% for initial AAIs and 44% for repeat prescriptions.
These figures highlight a significant failure to provide appropriate medical care to a vulnerable population. The reasons for this underprescription are complex and likely multifactorial (discussed further below).
Table 1: AAI Prescription Rates Among Schoolchildren with Food Allergies (CPRD Aurum Data, 2008-2018)
| Prescription Status | Percentage of Schoolchildren |
|---|---|
| Prescribed at Least One AAI | 44% |
| Prescribed Repeat AAIs | 34% |
| Prescribed at Least One AAI (experienced Anaphylaxis) | 59% |
| Prescribed Repeat AAIs (Experienced Anaphylaxis) | 44% |
The 2017 Legislative Change and its Limited Impact
recognizing the need for improved access to emergency treatment, UK legislation was amended in 2017. this change allowed schools to purchase ‘spare’ AAI devices without a prescription, for use in emergencies when a student’s own AAI is unavailable (e.g., forgotten, lost, or the student hasn’t been prescribed one).
However, the uptake of this provision has been slow.Researchers estimate that only around half of schools have implemented a spare AAI program. The primary barrier? Cost.
