Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | 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. | 19 | 828 | EG000 |
