Abstract
OBJECTIVE: To determine the efficacy in eradicating Staphylococcus aureus (SA) carriage of a 5-day preoperative decolonization bundle compared to 2 disinfectant soap showers, with both regimens self-administered at home.
DESIGN: Open label, single-center, randomized clinical trial.
SETTING: Ambulatory orthopedic, urologic, neurologic, colorectal, cardiovascular, and general surgery clinics at a tertiary-care referral center in the United States.ParticipantsPatients at the University of Minnesota Medical Center planning to have elective surgery and not on antibiotics.
METHODS: Consenting participants were screened for SA colonization using nasal, throat, axillary, and perianal swab cultures. Carriers of SA were randomized, stratified by methicillin resistance status, to a decolonization bundle group (5 days of nasal mupirocin, chlorhexidine gluconate [CHG] bathing, and CHG mouthwash) or control group (2 preoperative showers with antiseptic soap). Colonization status was reassessed preoperatively. The primary endpoint was absence of SA at all 4 screened body sites.
RESULTS: Of 427 participants screened between August 31, 2011, and August 9, 2016, 127 participants (29.7%) were SA carriers. Of these, 121 were randomized and 110 were eligible for efficacy analysis (57 decolonization bundle group, 53 control group). Overall, 90% of evaluable participants had methicillin-susceptible SA strains. Eradication of SA at all body sites was achieved for 41 of 57 participants (71.9%) in the decolonization bundle group and for 13 of 53 participants (24.5%) in the control group, a difference of 47.4% (95% confidence interval [CI], 29.1%-65.7%; P<.0001).
CONCLUSION: An outpatient preoperative antiseptic decolonization bundle aimed at 4 body sites was significantly more effective in eradicating SA than the usual disinfectant showers (ie, the control).Trial RegistrationClinicalTrials.gov identifier: NCT02182115.
