Background: Routine practice of antibiotic skin test (AST) before administering antibiotics is with little scientific basis. However, AST is frequently performed in real-world practice. We aimed to explore the current practice status of AST. Methods: All admission cases in Severance Hospital between January 2019 and December 2020 of patients at less than 19 years of age were collected retrospectively. AST results for 4 penicillins (ampicillin, ampicillin-sulbactam, amoxicillin-clavulanate, and piperacillin-tazobactam) and 6 cephalosporins (cefazolin, cefotaxime, cefotiam, cefpiramide, ceftriaxone, and flomoxef) as well as adverse drug reaction (ADR) reports were collected. Results: Among 36,381 hospitalization cases, 7,589 and 16,468 were administered penicillins and cephalosporins, respectively. Penicillins were administered without AST in 2,622 cases (35%), 2 (0.08%) of which showed ADR. Of the remaining 4,967 cases who received AST, 57 (1.1%) showed a positive reaction. For cephalosporins, 15,473 cases (94%) received antibiotics without AST. Among them, 17 cases (0.1%) showed ADRs. For 995 cases that rceived AST, 22 (2.2%) revealed a positive reaction. Among 79 cases who were AST positive, 10 took the original medication. Conclusion: The current practice of AST reveals heterogeneous and inconsistent patterns. This brings the need for a standardized guideline for the safe and effective use of antibiotics.
