Critical Gaps in Emergency Care Revealed in Fatal Child Anaphylaxis Study

Research presented at the Royal College of Emergency Medicine Conference on 28 April analyzed data from the National Childhood Mortality Database (NCMD) on fatal food-induced anaphylaxis in children aged 0-18 years between 2019 and 2023.

Two studies from the University of Bristol and Bristol Children's Hospital were presented.

The Lethal Window: Time and Treatment Gaps

In 74% of 19 fatal cases, no adrenaline autoinjector (AAI) or only a single dose was administered before cardiac arrest. The average time from symptom onset to cardiac arrest was just 14 minutes (data available for 12 cases).

"There is a very short window of time, often just minutes, in which appropriate treatment can potentially alter the clinical course."
— Dr. Tom Roberts, NIHR Academic Clinical Lecturer, University of Bristol

37% (7) of children did not carry an AAI at all. In 6 cases, neither the child nor their carers carried any AAI; in one case, only a single AAI was available, preventing a timely second dose.

All 19 children experienced cardiac arrest before reaching an emergency department.

Age Distribution of Fatalities

  • 9 (47%) aged 15-17 years
  • 8 (42%) aged 10-14 years
  • 2 (11%) under 10 years

Cause of Death: A Misplaced Priority?

Analysis of 17 cases where the failed bodily system could be identified found that lung failure (airway and breathing compromise) was the primary cause in all but one case. Current NHS guidelines focus on heart and circulatory failure.

"Airway and breathing problems were the most common causes of fatal food-related anaphylaxis in children. NHS guidelines currently focus on heart and circulatory failure; our findings suggest the focus should be on breathing issues."
— Dr. John Covney, lead author, Bristol Children's Hospital

Dr. Ben McKenzie, an Emergency Medicine doctor at the University of Melbourne who lost his 15-year-old son to food anaphylaxis, commented:

"This UK research confirms our Australian findings that fatal food anaphylaxis is driven by a closing of the airways in the lungs. We need to promote the chain of survival in anaphylaxis - get help, give adrenaline and for healthcare workers - get oxygen into the body as a priority."

A Call for Systemic Change

Professor Karen Luyt, Programme Director of the National Child Mortality Database and Professor of Neonatal Medicine at the University of Bristol, stated:

"Every child's death is a profound loss. By learning from every child death, we can identify where systems, services and support need to be improved to protect children's lives."
