Patient's perspective and public policy regarding anaphylaxis.

It is estimated that dose to 7 million Americans have food allergy. The incidence of food allergy, particularly peanut allergy, is believed to be on the rise. Several studies have shown that in spite of a patient's best efforts to avoid ingesting the allergy-causing food, reactions will occur. These reactions occur from incorrect ingredient information in food service or restaurant settings, incorrect product labels, or mistakes in label reading. In the hospital setting, patients are sometimes treated for an anaphylactic reaction in the emergency room but are not given instructions to see a specialist to determine the cause of their reaction, nor are they given a prescription for epinephrine to arm them to treat future allergic emergencies. Two studies of fatal and near fatal allergic reactions concluded that a delay in administration of epinephrine could have been a factor in the fatal outcomes. However, schools often do not have written emergency action plans in place for children with documented food allergy, and patients and caregivers often report not knowing when to use the epinephrine kit or how to use it. Until there is a cure for food allergy and anaphylaxis, avoidance of the allergen is key. There is much work to be done in education and public policy regarding anaphylaxis.
