Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to compare two types of skin preparation solutions (chlorhexidine gluconate-alcohol solution and povidone-iodine solution) that help eliminate harmful bacteria on the skin at the time of surgery for patients having revision arthroplasty surgery of the hip or knee.

The main outcome of interest for the definitive study is the need for re-operation for a wound complication or an infection of the prosthetic joint within one year after surgery.

For the pilot trial, our main interest is to determine feasibility of a definitive trial. Feasibility outcomes will include: ability to recruit patients, ability to randomize patients, ability to collect complete data, estimate the event rate of our primary outcome, ability to carry out data linkages and determine the accuracy of collected data.

Participants will be contacted at two time points after surgery to complete a 5-minute survey: after 30 days, and after 1 year.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this trial, participants will be assigned randomly to have their surgical skin site prepared for surgery with either chlorhexidine gluconate-alcohol solution or povidone-iodine solution. These are two types of solutions that have antiseptic properties, which means they help eliminate harmful bacteria on the skin at the time of surgery, and therefore, reduce the risk of infection. Surgeons routinely use either chlorhexidine-based or iodine-based skin preparation solutions at the time of surgery to sterilize the surgical area. However, we don't know which one works best for patients having revision joint replacement surgery. There is a small chance of having an allergic reaction to the chlorhexidine or iodine, but there is no additional risk by participating in this study, as these skin preparation solutions are routinely used in practice.

The main outcome of interest is the need for re-operation for a wound complication or an infection of the prosthetic joint within one year after surgery. Other key outcomes are surgical site infection, mortality, and readmission to hospital. Participants will be contacted 30 days after surgery to complete a survey online, by phone, or in person, which will take approximately 5 minutes to complete. All other outcome data will be collected by phone call, health records, routine hospital monitoring, or electronic registry data at thirty days and one year after surgery.

Study Groups

Chlorhexidine gluconate-alcohol solution

Chlorhexidine gluconate-alcohol solution is a type of solution that has antiseptic properties, which means it helps to eliminate harmful bacteria on the skin at the time of surgery, and therefore, reduce the risk of infection.

Group Type ACTIVE_COMPARATOR

Chlorhexidne Gluconate-Alcohol Skin Preparation

Intervention Type PROCEDURE

Participants will undergo skin antisepsis with 4% chlorhexidine gluconate pre-wash, followed by 2% chlorhexidine gluconate with 70% isopropyl alcohol skin preparation.

The surgical field to be sterilized will be at the discretion of the surgical team, but typically includes the distal torso to ankle for patients undergoing hip arthroplasty and proximal thigh to ankle for patients undergoing knee arthroplasty.

Pre-wash of the surgical area will be carried out using a wet chlorhexidine surgical scrub brush followed by immediate drying using towels. The definitive preparation will then be carried out using tinted chlorhexidine gluconate-alcohol sponges applied with forceps. The drying time and the minimum number of sponge packs used will comply with the product 'Instructions for Use'. The drapes can be applied as per the surgeon's usual approach and they will be treated according to the institution and surgeon's routine practice for draping and surgical site infection prevention.

Povidone-iodine solution

Povidone-iodine solution is a type of solution that has antiseptic properties, which means it helps to eliminate harmful bacteria on the skin at the time of surgery, and therefore, reduce the risk of infection.

Group Type ACTIVE_COMPARATOR

Poviodine-iodine Skin Preparation

Intervention Type PROCEDURE

Participants will undergo skin antisepsis with 7.5% povidone-iodine detergent pre-wash, followed by 10% povidone-iodine skin preparation.

The surgical field to be sterilized will be at the discretion of the surgical team, but typically includes the distal torso to ankle for patients undergoing hip arthroplasty and proximal thigh to ankle for patients undergoing knee arthroplasty.

Pre-wash of the surgical area will be carried out using iodine detergent soaked gauze pads followed by immediate drying using towels. The definitive preparation will then be carried out using povidone-iodine soaked gauze pads applied with forceps. The drapes can be applied as per the surgical team's usual approach and they otherwise will be treated according to the institution and surgeon's routine practice for draping and surgical site infection prevention.
