Whether different types of skin preparation and suture can reduce the incidence of surgical site infection at 30 days post-operatively in patients undergoing abdominal surgeries that are anticipated to have either clean-contaminated or contaminated/dirty wound contamination
1. To assess whether either (1) 2% alcoholic chlorhexidine versus 10% povidone-iodine for skin preparation, or (2) triclosan-coated suture versus non-coated suture for fascial closure, can reduce surgical site infection at 30-days post-surgery for each of (i) clean-contaminated and (ii) contaminated or dirty abdominal surgery.
2. To assess the impact of the interventions on secondary clinical outcomes up to 30 days post-surgery including: SSI at discharge, mortality, unplanned wound opening, re-operation, length of hospital stay, re-admission, and return to normal activities.
