The study included all patients with documented penicillin allergy and GBS positive status during routine prenatal care. Records were reviewed for allergy severity\/risk and antibiotic administered for GBS prophylaxis. Allergy severity\/risk was based on whether there was a documented reaction in the electronic health record and the presence or absence of anaphylaxis, angioedema, respiratory distress, or urticaria. Patients were classified as receiving appropriate or inappropriate intrapartum antibiotic prophylaxis based on their allergy risk stratification and whether they received standard (e.g. penicillin, cefazolin) or alternative (e.g. clindamycin, vancomycin) antibiotics. The primary outcome was inappropriate prophylaxis, defined as receiving an alternative antibiotic in the setting of a low-risk penicillin allergy. Secondary maternal and neonatal outcomes were abstracted and compared based on appropriateness of antibiotic selection.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec id=\"j_jpm-2024-0596_abs_003\">\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>There were 18,931 unique patient encounters during the study period, of whom 1,262 (6.7\u202f%) had a documented penicillin allergy. Of patients with penicillin allergies, 196 were GBS-colonized. Of the 86\u00a0GBS-colonized patients with low-risk penicillin allergies, 54 (62.8\u202f%) received inappropriate antibiotic prophylaxis (i.e.\u00a0received alternative antibiotics despite a low-risk allergy). Fewer than 7\u202f% of pregnant patients developed complications, including chorioamnionitis, endometritis, or surgical site infection within 30\u00a0days.
