Background: Cefazolin is the most common first-line antibiotic to prevent surgical-site infections. Patients with penicillin allergy labels often receive alternative antibiotics, which is associated with increased rates of surgical-site infections, multi-drug-resistant infections, and cost.
Objective: We sought to determine whether a hospital-wide guideline recommending first-line surgical prophylaxis in patients with penicillin allergy labels can increase the use of cefazolin without compromising safety.
Methods: We conducted a retrospective cohort study of adult surgical patients with penicillin allergy labels. The main intervention was updated hospital-wide surgical guidelines recommending first-line prophylaxis in most patients with penicillin allergy labels. We compared the preintervention and postintervention groups. The primary outcome was cefazolin use. Secondary perioperative outcomes included alternative antibiotic use and severe allergic episodes (anaphylaxis).
Results: The total sample comprised 7187 patients with penicillin allergy labels who underwent 8945 surgical encounters (median age [interquartile range], 61 [46-71] years); 4891 [68%] female). Cefazolin was used in 2256 (73%) patients in the preintervention group and 3390 (83%) patients in the postintervention group ( < .001), with an adjusted odds ratio of 1.87 (95% CI, 1.67-2.10). There was a decrease in the use of clindamycin from 14% to 8% ( < .001) and gentamicin from 16% to 8% ( < .001). There were no episodes of severe allergic reactions among patients who received guideline-directed therapy.
Conclusions: A hospital-wide guideline can improve use of cefazolin in surgical patients with penicillin allergy labels without increasing the risk for severe allergic reactions. National and international guidance should be considered to enhance administration of cefazolin in surgical patients with penicillin allergy labels.

Introduction: Erroneous penicillin allergy labels are associated with significant health and economic costs. This study aimed to determine whether deep learning-facilitated proactive consultation to facilitate delabelling may further enhance inpatient penicillin allergy delabelling.
Methods: This prospective implementation study utilised a deep learning-guided proactive consultation service, which utilized an inpatient penicillin allergy delabelling protocol.

Evaluating penicillin allergy labels and expanding access to preferred treatment options safely is of critical public health importance. Most patients with penicillin allergy labels are not allergic, and even in those with verified allergy, sensitization wanes over time. However, sensitization is complex and while a patient may have a negative penicillin allergy evaluation (including a drug challenge), resensitization can occur, raising a risk of a subsequent reaction upon exposure.

Background: Penicillin allergy is reported in 5% to 15% of the world population, with 3% to 10% of pregnant women reporting the same. However, more than 90% of these patients can tolerate penicillin after appropriate evaluation. Penicillin is indicated for various issues that arise in pregnancy, and a history of allergy can have negative individual and public health consequences.
