Nurse-and-allergist provocation pathway for penicillin allergy delabelling (PANDA)

Provocation After Nurse-Directed Assessment (PANDA) Study

Observational The University of Hong Kong · NCT07127835

This project will try a nurse-and-allergist team approach to remove incorrect penicillin allergy labels in patients treated at participating hospitals, and compare it to the usual allergist-only pathway.

What this trial studies

PANDA is an observational comparison of a nurse-allergist collaborative delabelling service versus a traditional allergist-led service for patients with a documented penicillin allergy across three Hong Kong hospitals. Patients are stratified by clinical risk and, where appropriate, undergo nurse-directed history-taking and drug provocation testing with allergist oversight; clinical outcomes, safety events, and quality-of-life measures are recorded. The study collects demographic and clinical data from inpatient and outpatient records and compares resource use and cost-effectiveness between the two care models. Exclusions include patients without a complete medication/allergy history, those with only short-term emergency records, or recent use of steroids or antihistamines that would affect testing.

Who should consider this trial

Good fit: Patients with a documented penicillin allergy who are receiving care at one of the participating Hong Kong hospitals and can provide a complete medication and allergy history.

Not a fit: Patients unable to provide a full allergy or medication history, those with only emergency or short-term records, or those who recently used steroids or antihistamines likely will not benefit from this delabelling approach.

Why it matters

Potential benefit: If successful, the collaborative pathway could safely remove incorrect penicillin allergy labels faster and at lower cost, increasing appropriate antibiotic options for patients.

How similar studies have performed: Previous programs using risk stratification and direct drug provocation for penicillin delabelling, including nurse-led pathways, have shown good safety and high rates of successful delabelling.
