Because there is no process to safely and rapidly diagnose true penicillin allergy in a critical care setting, pediatric providers are reluctant to prescribe penicillin to children with a reported allergy. In this study, a three-tier penicillin testing process was used to evaluate the accuracy of a parent-reported penicillin allergy questionnaire in identifying children likely to be at low risk for penicillin allergy in an ED setting.
The parents (597) of children aged 4-18 years with a history of parent-reported penicillin allergy completed an allergy questionnaire; 51% (302) of the children were categorized as low risk, and 100 of them completed allergy testing by using a standard three-tier testing process. Of these 100 children, 100% had negative results for penicillin allergy. The allergy designation subsequently was removed from each child’s chart.“Our results in the current study highlight that the high percentage of patients reporting a penicillin allergy to medical providers are likely inconsistent with true allergy,” concluded Dr. Vyles and his associates.
