- The Clinical Impact of Antibiotic Allergy Labels on One‐Year Outcomes of Solid Organ Transplant Recipients Sashi Niranjan Nair Paul Bigliardi Lauren Fontana Clinical Transplantation ABSTRACT Antibiotic allergy labels (AALs) are common and often incorrect. They have many potential impacts, including the use of broader‐spectrum antibiotics and suboptimal treatment of infections. The impact of inaccurate allergy labels on post‐transplant outcomes in the solid organ transplant population is not well described. We performed a retrospective review of 2,373 consecutive solid organ transplants occurring between 2011 and 2021, to analyze the impact of AALs, specifically penicillin, on outcomes in the first year after transplantation. Three hundred and twenty‐two patients (13.6%) had a penicillin allergy label, while 572 patients (24%) had at least one antibiotic allergy label. Patients with a penicillin allergy label were more likely to have a positive Clostridioides difficile test ( p = 0.021). Patients with allergy labels also had significantly more utilization of alternative antimicrobial agents ( p < 0.001) and longer inpatient hospital durations ( p = 0.013). This study suggests that AALs may be a risk factor for inferior outcomes after solid organ transplantation and could represent a modifiable target for pre‐transplant optimization. 10.1111/ctr.70498 http://creativecommons.org/licenses/by/4.0/
