Pathogen Transmission Clinical Trial
Official title:
Evaluation of the Impact of Germicidal Light (Indigo-Clean) on Intraoperative S. Aureus Exposure
Operating room S. aureus exposure has been directly linked to postoperative infections and is
therefore an important target for infection prevention. Visible light (non-ultraviolet
spectrum) at 405nm has been shown to be germicidal. We hypothesize that use of this light in
operating rooms will reduce S. aureus transmission occurring within and between patients and
reduce surgical site infections (SSIs). Visible light is safe for routine, continual
exposure, and is less harmful than sunlight. We plan to install ambient, germicidal lighting
in 4 operating rooms. This ambient light is not directly applied to patients (does not
involve the surgical procedure lights). Patients will undergo surgery according to usual
practice. We will conduct a case-control study where operating rooms with surgeries with the
lights are matched to operating rooms with surgeries without lights.
In Aim 1, 4 OR-pairs will be observed each day over an anticipated 103 working days for the
primary outcome of S. aureus transmission events over a total minimum study period of 5.2
months (103 working days).
