Clinical Scorecard: Pilot Study on Direct Amoxicillin Challenges for Assessing Penicillin Allergy During Pediatric Group Visits in Primary Care
At a Glance
Category
Detail
Condition
Penicillin allergy label (PAL) in pediatric patients
Key Mechanisms
Direct oral amoxicillin challenge testing without preceding skin testing to delabel penicillin allergy
Target Population
Children aged 2–17 years with a penicillin allergy label receiving care in primary pediatric clinics
Care Setting
Outpatient pediatric primary care clinics using group visits
Key Highlights
95% of children undergoing direct amoxicillin challenge were delabeled with no severe reactions observed.
Direct oral challenge is a safe and effective method for penicillin allergy testing in children, with very low rates of anaphylaxis.
Group visits led by pharmacists optimize clinic resources and address barriers such as time, space, and staffing in primary care settings.
Guideline-Based Recommendations
Diagnosis
Use direct oral amoxicillin challenge without preceding skin testing for children without history of severe cutaneous adverse reactions or organ injury.
Screen patients on the day of testing for acute illness or symptoms that may require rescheduling.
Management
Perform a 2-step graded amoxicillin challenge: 50 mg dose followed by 5-minute observation, then 200 mg dose followed by 60-minute observation.
Manage mild reactions with oral antihistamines or topical corticosteroids as appropriate.
Have an escalation plan involving nursing staff and pediatricians for more severe reactions.
Monitoring & Follow-up
Observe patients for immediate reactions during the challenge visit.
Conduct follow-up phone calls 7–10 days post-challenge to assess for delayed reactions.
Risks
Mild cutaneous reactions may occur; anaphylaxis is rare but preparedness with epinephrine autoinjector is essential.
Exclude patients with history of mucosal ulcers, skin peeling, severe cutaneous adverse reactions, or penicillin-induced organ injury.
Patient & Prescribing Data
Pediatric patients aged 2–17 years with penicillin allergy labels in urban community primary care clinics
Direct amoxicillin challenge testing in group visits led by pharmacists is feasible, safe, and results in high rates of penicillin allergy delabeling.
Clinical Best Practices
Engage families through education and outreach to increase acceptance of penicillin allergy testing in primary care.
Utilize pharmacist-driven group visits to optimize clinic resources and overcome barriers to allergy testing implementation.
Ensure trained personnel and emergency medications are available during challenges to manage potential adverse reactions.
Implement a structured follow-up protocol to identify delayed hypersensitivity reactions.
