In 22/84 (26.2%) assessments, the patient tool determined a higher risk category than the allergist. This was primarily due to differences in perceived timing and description of symptoms when completing the patient tool compared to what was reported to the allergist.
Of the five patients stratified to a lower risk category using the patient tool (Figure 1), one responded to the self-assessment accounting for an initial exposure with mild symptoms, whereas the allergist accounted for a second exposure with more concerning symptoms. The other four patients misread the first question and incorrectly indicated that they had never taken a penicillin-based antibiotic so were miscategorized as not allergic.
