Not every allergic emergency needs an ER visit. A new validated prediction model can identify children with anaphylaxis who are at low risk of needing additional epinephrine after a single prehospital dose — meaning many could safely skip the emergency department. The model correctly flagged 93% of high-risk cases while ruling out life-threatening presentations with 99% accuracy.
Not every allergic emergency needs an ER visit. A new validated prediction model can identify children with anaphylaxis who are at low risk of needing additional epinephrine after receiving a single prehospital dose — meaning a significant portion could safely be managed in the community rather than rushing to the emergency department (ED).
Researchers analyzed data from 2,318 children with anaphylaxis across multiple centers. They found three key pre-ED risk factors that predict the need for further epinephrine: a history of asthma, cardiovascular symptoms before the initial epinephrine dose, and persistent or new symptoms after that dose. Children without any of these factors were classified as low risk.

Why it matters: Unnecessary ED visits are costly, stressful, and resource-intensive. This tool, aligned with 2023 Practice Parameter recommendations, could help clinicians and families make safer, smarter decisions about post-anaphylaxis care — reducing ED overcrowding while keeping high-risk kids protected.
