Impact of Penicillin Allergy on Time to First Dose of Antimicrobial Therapy and Clinical Outcomes

Patients with a penicillin allergy had a prolonged time to first dose of antibiotic therapy. No significant differences were found in total antibiotic duration, length of stay, or 30-day readmission rate. The small sample size, older population, and single-center nature of this study may limit the generalizability of the present findings to other populations.
