Previous literature suggests that there is increased prevalence of penicillin drug allergy in female patients in the outpatient setting. However, this is poorly described in the inpatient setting.  <jats:bold>Objective:<\/jats:bold>\n This study was performed to determine whether female sex is an independent risk factor for penicillin allergy in the inpatient setting.  <jats:bold>Methods:<\/jats:bold> A retrospective review of electronic medical records (January 1, 2001-December 31, 2017) was performed for patients with\n a history of penicillin allergy who underwent penicillin skin testing (PST). Each chart review included the age at initial skin testing, sex, medications, and medical co-morbidities. The study was approved by the institutional review board.  <jats:bold>Results:<\/jats:bold> 30,883 patients underwent\n PST with 29,354 and 1,529 occurring in the outpatient and inpatient setting respectively. 170 patients tested positive with a \u2265 5x5 wheal. Of the 170 positive patients, 122 were female (72%) and 48 were male (28%). 15 patients tested positive in the inpatient setting. Of the 1506 adult\n patients tested in the inpatient setting, 809 were female and 697 were male. 12 females (92.3%) and 1 one male (7.7%) tested positive with a \u2265 5x5 wheal (OR-10.5; 95% CI-1.4-80.8; p-value=0.02). 23 pediatric patients were tested in the inpatient setting. Two pediatric male patients were\n positive and no female pediatric patients tested positive (OR-1.7; 95% CI-0.5-5.9; p-value=0.5).  <jats:bold>Conclusion:<\/jats:bold> In the inpatient setting, adult females are 10 times more likely to have a positive PST compared to males. Female sex may be a potential risk factor for objective\n penicillin drug allergy in the inpatient setting.<\/jats:p>","DOI":"10.2500\/aap.2022.43.210002","type":"journal-article","created":{"date-parts":[[2022,3,23]],"date-time":"2022-03-23T10:47:26Z","timestamp":1648032446000},"page":"163-167","source":"Crossref","is-referenced-by-count":15,"title":["Female
