Abstract
BACKGROUND: Surgical site infection in vascular surgery has a reported incidence of up to 19%. A novel method of reducing this rate of infection is dressings coated with dialkylcarbamoylchloride (DACC), a hydrophobic wound contact layer that binds bacteria and removes them from the wound bed. Early research has suggested that DACC-coated wound dressings are effective in reducing surgical site infection when applied to wounds healing by primary intention post-operatively, therefore this trial aims to assess the feasibility of producing high-quality evidence assessing this theory. METHODS: Patients undergoing clean or clean-contaminated vascular surgery will be randomised to have their surgical wounds dressed with a DACC-coated dressing or a non-coated occlusive absorbent post-operative dressing. All other aspects of their peri-operative care will be standardised or carried out in line with hospital policy. Wound assessments will be carried out between day 5-7, day 30 (± 3 days) and 6 months post-operatively (± 7 days) by a blinded assessor using the ASEPSIS scoring tool. Quality of life data using EQ-5D and SF-36, resource use and mortality data will also be collected. This feasibility trial will dictate the conduct of a full-scale trial through the collection of data on recruitment and retention rates, and fitness-for-purpose of the follow-up arrangements. DISCUSSION: Surgical site infections are now the second most common hospital acquired infections with a significant cost implication. The aim of the DRESSINg trial is to investigate the effectiveness of a novel preventative measure at reducing wound infections post-surgery and will provide robust evidence to support or deny its use.
