COMPARATIVE STUDY OF βS-LACTAM DE-LABELING ON THE FREQUENCY OF PERI-OPERATIVE VANCOMYCIN USE

Vancomycin is the antibiotic of choice in β-lactam allergic adults undergoing surgical antibiotic prophylaxis. Because it is a suboptimal option, in 2015 a pre-operative drug allergy screening program began at the Montreal General Hospital (MGH). It de-labeled 94 % of patients evaluated, reducing vancomycin use to 3 %. To validate the program effectiveness a prospective study comparing the Royal Victoria Hospital (RVH), which lacked de-labeling was undertaken.The aim of the study was to determine the effect of a de-labeling program on vancomycin use.
