Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment arms will be:
• Arm 1 – All patients will use an all-over chlorhexidine body wash (minimum 50ml of Chlorhexidine gluconate 4% w/v solution) the night before and morning of the surgery and receive placebo antibiotics as per those is arm 3 – Control.
• Arm 2 – Clindamycin: Patients will be administered 450mg of oral clindamycin 30-60 mins before surgery in the waiting room to enable monitoring for adverse reactions and an equal second dose at home 6hrs post-surgery Participants will perform a placebo bacterial load reduction following the same protocol as in Arm 1.
Participants will be asked to complete a treatment diary to monitor adherence to the intervention.

Comparator / control treatment
Arm 3 – Control: This group represents normal standard of care in which no active bacterial load reduction or active clindamycin will be administered. Patients will receive placebo oral capsules containing an inert vehicle powder for clindamycin (in lieu of clindamycin), placebo saline wash (in lieu of chlorhexidine) and placebo soft white paraffin ointment (in lieu of nasal mupirocin). Placebo treatments will follow the same time schedule as their active counterparts in arms 1 and 2.

Summary
Brief summary
This study will investigate the effectiveness of two interventions to prevent surgical site infection after below-knee surgery for skin cancer in adults.

Who is it for?
You may be eligible for this study if you are aged 18 years or older, you have been diagnosed with a skin cancer below the knee which requires a complex surgical technique (flap or graft repair), and you are a patient at one of the participating centres in Queensland.

Study details
Participants who choose to enrol in this study will be randomly allocated by chance (similar to flipping a coin) to one of three groups. Participants allocated to the first group will be asked to take an oral tablet pre- and post-surgery, and use an antibacterial body wash prior to their surgery. Participants allocated to the second group will also be asked to take a pre- and post-surgery antibiotic dose and use a provided body wash prior to their surgery. Participants allocated to the third group will be asked to take an oral tablet pre- and post-surgery and use a provided body wash prior to their surgery.

It is hoped this research will determine whether use of oral antibiotics with or without antibacterial body wash has any impact on the incidence of post-surgical skin infections in patients undergoing surgical removal of below the knee skin cancers. If one or both of these measures is found to be effective, a larger trial enrolling a greater number of participants may be undertaken.
