5480FALCON is a Pragmatic multi-centre trial testing measures to reduce superficial or deep skin infection following abdominal surgery in low and middle income countries. The trial will recruit patients undergoing abdominal surgery. Recruited participants will be randomly assigned to four arms to receive different combinations of skin preparation and sutures for would closure:
A. In this arm surgeon will use 2% alcoholic chlorhexidine for skin cleansing and non-coated suture for wound closure; B. In this arm surgeon will use 2% alcoholic chlorhexidine for skin cleansing and triclosan coated suture for wound closure; C. In this arm surgeon will use for operation 10% aqueous povidone-iodine for skin cleansing and non-coated suture for wound closure; D. In this arm surgeon will use 10% aqueous povidone-iodine for skin cleansing and triclosan-coated suture.
FALCON is a pragmatic, blinded (patient and outcome assessor), 2x2 factorial, stratified, multi-centre randomised controlled trial, with an internal pilot, to evaluate measures to reduce Surgical Site Infection (SSI) rates in patients undergoing surgery with an abdominal incision.
Surgical site infection (SSI) represents a major burden for patients, doctors, and health systems across all settings. SSI is the commonest postoperative complication worldwide and the commonest healthcare-associated infection in low and middle income countries (LMICs). SSIs cause pain, discomfort, disability, and increase the time taken to return to work (3). SSIs increase healthcare costs in all health settings. Whilst there is no direct data on the costs of SSI in LMICs, within the UK National Health Service, SSIs cost approximately £3500 per patient and £700 million per year in total. The impact of increased healthcare costs on patients, communities, and providers can be major in LMICs where personal income is low and patients may be required to pay for their own treatment. SSI has also been associated with one-third of postoperative deaths and accounts for 8% of all deaths caused by a hospital acquired infection.
Strata in FALCON trial are defined according to the anticipated category of wound contamination: (1) clean-contaminated and (2) contaminated/dirty. Eligible patients will be randomised at the level of the individual in a 1:1:1:1 ratio between:
A. 2% alcoholic chlorhexidine and non-coated suture B. 2% alcoholic chlorhexidine and triclosan-coated suture C. 10% aqueous povidone-iodine and non-coated suture D. 10% aqueous povidone-iodine and triclosan-coated suture.
Participant will be recruited from hospitals in Low and Middle Income Countries (LMICs). Participants who is undergoing abdominal surgery with an anticipated clean-contaminated, contaminated or dirty surgical wound will be selected to enter the trial.
The 6 month internal pilot will assess the feasibility of recruitment, compliance with treatment allocation and patient retention and follow-up rates. The main RCT will recruit 5480 participants.
Interventions: 2% alcoholic chlorhexidine non-coated suture
Interventions: 2% alcoholic chlorhexidine triclosan coated suture
Interventions: 10% povidone-iodine non-coated suture non-coated suture
Interventions: 10% povidone-iodine triclosan coated suture
2%alcoholic chlorhexidine + triclosan-coated suture. Intervention: skin preparation with 2%alcoholic chlorhexidine in combination with triclosan-coated suture for abdominal fascia closure.
10% povidone-iodine and non-coated suture. Intervention: skin preparation with 10% povidone-iodine in combination with non-coated suture for abdominal fascial closure.
2%alcoholic chlorhexidine + non-coated suture. Intervention: skin preparation with 2%alcoholic chlorhexidine in combination with non-coated suture for abdominal fascial closure.
10%povidone-iodine/triclosan-coated suture. Intervention: skin preparation with 10% povidone-iodine in combination with triclosan-coated suture for abdominal fascial closure.
Inclusion Criteria: Patients with at least one abdominal incision that is ≥5cm (open or laparoscopic extraction site), with an anticipated clean-contaminated, contaminated or dirty surgical wound. Patients undergoing emergency (surgery on an unplanned admission) or elective (surgery on a planned admission) operations. Any operative indication, including trauma surgery. Patient able and willing to provide written informed consent (signature or a fingerprint). Paediatric and adult patients. This criteria is made country-specific. Each country decides the lower age limit for the trial. This is dependent on country-specific regulatory approvals. Age eligibility will vary by country. Exclusion Criteria: Patients with a documented or suspected allergy to iodine, shellfish, or chlorhexidine skin preparation solution. Patient unable to complete post-operative follow-up (i.e. will not be contactable after discharge).
