Trial Outcomes & Findings for Pre-operative Aqueous Antiseptic Skin Solutions in Open Fractures (NCT NCT03385304)

NCT ID: NCT03385304

Last Updated: 2023-03-31

Results Overview

Guided by the Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network reporting criteria (2017): Date of event for infection may occur from the date of fracture to 30 days after the definitive fracture management surgery; AND involves only skin and subcutaneous tissue of the incision; AND patient has at least one of the following: 1. purulent drainage from the superficial incision. 2. organisms identified from an aseptically obtained specimen from the superficial incision or subcutaneous tissue by a culture or non-culture based microbiologic testing method which is performed for purposes of clinical diagnosis or treatment 3. superficial incision that is deliberately opened by a surgeon, and culture or non-culture-based testing is not performed. AND patient has at least one of the following signs or symptoms: pain or tenderness; localized swelling; erythema; or heat. 4. diagnosis of a superficial incisional SSI by the surgeon.

Participant Flow

Recruitment occurred between April 8, 2018, and June 8, 2021 at 14 hospitals in Canada, Spain and the USA. Eligible patients were adults aged 18 years or older with an open extremity fracture treated with a surgical fixation implant. For inclusion, the open fracture required formal surgical debridement within 72 hours of the injury.

To ensure wide generalizability to routine practice, the protocol allowed prewashing of the operative extremity with alcohol or other antiseptics before performing the final skin antisepsis with the study solution. In addition to ensuring trial feasibility and protocol adherence, this decision pragmatically allowed the intact skin to receive mechanical scrubbing or partial alcohol antisepsis at the treating surgeon's discretion.

Measure
10% Povidone-iodine (1% Free Iodine) in Purified Water
The povidone-iodine solution will contain 10% povidone-iodine (1% free iodine) in purified water as the only active ingredient. Operating room personnel will apply the solution to the operative site as the final preoperative skin antisepsis preparation immediately prior to commencing surgical fixation. They will apply the solution as per manufacturer's directions for use (e.g., technique of application, duration of application, drying time, drying techniques, replacement of draping, etc.). 10% povidone-iodine (1% free iodine) in purified water: Participant recruitment will begin with the clinical sites using their assigned pre-operative antiseptic skin solution for all open fracture surgeries for a two-month period. 4% chlorhexidine gluconate (CHG) in purified water: Once the first intervention phase is completed, each site will crossover to the opposite study solution. Each site will need to develop local procedures to ensure a successful crossover. They will use the second solution for all open fracture surgeries for a two-month period, and will then crossover back to the solution in the first intervention phase.

Population: Primary and secondary outcomes were evaluated using a complete case analysis. For that reason, the overall number of participants analyzed differs from the numbers provided under the Participant Flow module.

Common examples include any unplanned fracture-related surgery that is associated with an infection at the operative site or contiguous to it, a wound-healing problem, or a fracture delayed union or non-union.
