Measure
Group 1 Standard
Trainees received a preventive medicine briefing augmented with SSTI and MRSA SSTI prevention information and personal hygiene instructions. Trainees seeking medical care for an SSTI received standardized SSTI care (e.g., antimicrobial therapy, wound management, patient education) at the Troop Medical Clinic. High-touch common surfaces within the battalion areas were cleaned with standard standard Environmental Protection Agency registered disinfectants.
Group 2 Enhanced Standard
Trainees received the components of the Standard group and were instructed to take an additional 10-minute shower with soap and a wash cloth every week. They were also issued a first aid kit. Supplemental SSTI education for trainees and drill sergeants was also provided (e.g., pocket cards, posters). Drill sergeants received briefings on SSTI and skin inspection/minor wound care.
Group 3 Chlorhexidine
Trainees received the components of the Standard and Enhanced Standard groups and were offered chlorhexidine body wash (4% chlorhexidine gluconate, Hibiclens®, Mӧlnlycke Heath Care, Norcross, Georgia) to use with a wash cloth after using their personal soap for the additional once-weekly shower. Trainees were provided with verbal and written/graphic instructions for use.
