A quality improvement initiative to improve primary care referral rates for penicillin allergy delabeling.

BACKGROUND

Of the US population, 10% reports a penicillin allergy but more than 90% can ultimately tolerate penicillin. Confirmation of these allergies in the pediatric population may improve future health outcomes and decrease costs. Referring patients for confirmatory testing is the first step in clarifying penicillin allergies.

OBJECTIVE

To increase the number of referrals of patients with listed penicillin allergies from the University of California, San Diego academic general pediatrics clinics to Rady Children's Hospital allergy clinics using an educational session and a best practice advisory (BPA) in the electronic medical record.

METHODS

An educational session with attendings and 3 plan-do-study-act (PDSA) cycles were completed using a BPA alert that triggered for all patients with a documented penicillin-class drug allergy to draw attention and facilitate referral. The BPA was modified at each PDSA cycle based on physician input.

RESULTS

At baseline, 1.9% of referrals to the allergy clinic were for penicillin-class drug allergies. After an attending physician educational session, the percentage increased to 13.7%. The BPA was implemented with further increase to 27.8% of all allergy referrals in the course of 3 PDSA cycles. Not all patients with penicillin-class drug allergies were referred, and the reasons were documented when the physicians dismissed the BPA. Physicians did not refer 35% of the time because of time constraints, as opposed to patient or parent disinterest, which was 8% of the time.

CONCLUSION

Referrals to the allergist for confirmatory testing in patients with listed penicillin allergies increased by more than 10 fold. This study illustrates successful tools to support delabeling.
