Food, drug, insect sting allergy, and anaphylaxisAnalysis of food-allergic and anaphylactic events in the National Electronic Injury Surveillance System
Section snippets
The NEISS Database
The NEISS currently collects data from 98 hospital EDs geographically dispersed throughout the US that have a minimum of 6 beds and that provide 24-hour emergency services, excluding psychiatric and penal institutions. On the basis of NEISS sample design and implementation,2, 3 the data ascertained by the system represent a stratified probability sample that can be weighted to produce national estimates of the number of adverse events treated in US EDs.3
In this pilot study, we used 2 months of
Results
Overall, a total of 1161 food-related events were ascertained by NEISS from 34 participating EDs for the period August 1 through September 30, 2003. Although a total of 806 (69 %) events were accompanied by 1 or more key words that suggested a possible allergic etiology, only 173 (15%) met the criteria to be considered food-allergic events, 118 of which reported “allergy” or “allergic reaction,” and 141 of which had accompanying medical records. The excluded events comprised 419 events that
Discussion
Accurate assessment of the nature and incidence of severe food allergy––related reactions is needed for monitoring the public health effect of food allergy and for focusing resources on important preventative strategies. It is evident that many severe food-allergic reactions, including anaphylaxis, present to EDs. Thus, NEISS data, which are made up of nationally representative ED information on consumer product–associated injuries, can be used to obtain clinically and epidemiologically
