Penicillin allergy de-labeling: Adaptation of risk stratification tool for patients and families

Penicillin allergy de-labeling: Adaptation of risk stratification tool for patients and familiesTo the Editor, Penicillin allergy is a common drug allergy diagnosis reported in 10% of the population .However, over 90% of patients are found to be non-allergic upon allergist assessment .This discrepancy is often due to misclassification of symptoms in patients who receive penicillin-based antibiotics .Erroneous penicillin allergy labeling is a public health problem associated with use of alternative antibiotics that are generally less effective, more toxic, or more costly .We previously developed and validated a decision support tool to assess penicillin allergy risk.It has been adapted into a mobile version that can be administered by various healthcare professionals.The goal of this study is to adapt the existing mobile tool into a patient-friendly version and validate it against the gold standard (allergist) assessment.If effective, this will empower lay individuals to conduct their own assessments and gain knowledge about levels of allergy risk.With this knowledge, patients can better advocate for themselves, potentially increasing efficiency of healthcare visits and reducing wait times for subspecialist assessments.
