The goal of this clinical trial is to learn if reducing bacterial load on the skin and nostrils with topical antibacterial soap and ointment, respectively, reduces rate of infection in surgical sites on lower leg wounds left open to heal in adults undergoing skin cancer surgery. The main question it aims to answer is: Does Hibiclens antibacterial skin cleanser and mupirocin antibacterial ointment applied to nostrils prior to surgery lower the number of times participants develop an infection in their open wound on the lower leg? Researchers will compare the treatment group to the standard of care, which involves no treatment prior to surgery, to see if topical antibiotics applied prior to surgery affect infection rates between the two groups. Participants randomized to the treatment group will: Shower with Hibiclens once daily for 5 days prior to the day of surgery and apply mupirocin to the nostrils twice daily for 5 days prior to the day of surgery. They will then send pictures of their surgical site to monitor for signs of infection at 2-week and 4-week post-operation. Participants randomized to the control group (standard of care) will: NOT apply the topical antibacterials prior to the day of surgery. They will then send pictures of their surgical site to monitor for signs of infection at 2-week intervals for 1 month after surgery.
The investigators hypothesize that the use of a personal hand hygiene system (SafeHavenTM) by anesthesia providers in the adult operating room, combined with a novel infectious pathogen tracking system (OR PathTrac) will decrease participant exposure to pathologic bacteria in the adult operating room.
This is a Phase 3 multi-center, group-randomized, crossover trial to compare nasal antimicrobial photodisinfection therapy (aPDT) with standard of care for prevention of surgical site infections in patients undergoing major elective, urgent, or emergent surgeries in a hospital setting. The main outcomes are to: 1. compare the efficacy, and 2. estimate the safety of applying nasal (aPDT) before surgery in reducing the incidence of SSIs within the initial 30 days after surgery compared to standard of care (SOC). Participants in the intervention group will receive aPDT prior to surgery on the day of surgery. Participants in the control group will receive standard of care surgical site prevention measures prior to surgery.
