Remove incorrect beta-lactam (penicillin and cephalosporin) allergy labels to expand antibiotic options for patients with blood cancers.

Optimizing Antibiotic Selection in Hematologic Malignancy Patients With Reported Beta-lactam Allergy - Intervention

Not applicable Interventional University of Pennsylvania · NCT07133074

This project tests a pharmacist-led process to remove incorrect penicillin or other beta-lactam allergy labels in hospitalized patients with blood cancers so they can receive preferred antibiotics and potentially have better outcomes.

What this trial studies

The RENEW-IN intervention uses a pharmacist-led, multi-step algorithm to review and delabel reported beta-lactam (BL) allergies among patients hospitalized with hematologic malignancies. The process includes a detailed allergy history, RENEW-IN algorithm-guided selection for additional testing, electronic medical record review, and pharmacist-directed delabeling when appropriate. The trial measures changes in antibiotic prescribing and clinical outcomes, including BL use and infection-related complications. Patients with histories of severe cutaneous adverse reactions are excluded from the intervention.

Who should consider this trial

Good fit: Hospitalized patients with a hematologic malignancy who have a documented history of a beta-lactam allergy and are admitted to the inpatient oncology service are the ideal candidates.

Not a fit: Patients with documented severe cutaneous adverse reactions such as Stevens-Johnson syndrome, toxic epidermal necrolysis, DRESS, or other exclusionary severe reactions are unlikely to benefit from delabeling.

Why it matters

Potential benefit: If successful, more patients with hematologic malignancies could safely receive beta-lactam antibiotics, potentially reducing infection-related complications and improving antibiotic effectiveness.

How similar studies have performed: Prior delabeling programs in general hospitalized populations have shown that roughly 90% of reported beta-lactam allergies are not true allergies and can be safely removed, but this approach has not been well studied in patients with hematologic malignancies.
