PVI to Prevent S. Aureus SSI After Fixation of HELEF (POTENT Study)
Study Details
Study Description
Brief Summary
The purpose of this study is to see whether applying povidone iodine (PVI) to the noses of patients undergoing lower extremity (leg, ankle, or foot) orthopedic fixation procedures of high-energy lower extremity fractures (HELEF) will decrease the patients' risk of surgical site infections (SSI), particularly those caused by Staphylococcus aureus.

Phase 4 |
Detailed Description
These patients are at high risk of SSI but given the rapidity with which they need their operations, interventions that take time are difficult or impossible to use in this patient population. This study will involve identifying patients with HELEF and applying PVI to their nares within 60 minutes before their surgical incisions are made and again approximately 12 hours after the first dose. The investigators will abstract information from the patients' medical records about their demographics, underlying illnesses, injury severity, the surgical procedures, and SSI for the 6 months following their operations and the investigators will see them during their routinely scheduled visit at about 6 months to ask them whether they were treated for SSI by providers outside of our system. For patients who do not return for follow up, the investigators will try to contact them to determine if they had signs or symptoms of SSI or were treated for SSI outside of our system.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Nasal Povidone-Iodine Decolonization Intervention Intranasal povidone-iodine (PDI Profend) will be applied to the patients' noses 60 minutes before surgery to repair HELEF and approximately 12 hours after the first application. If the patient will have additional HELEF repair in the 6 month followup period, intranasal PVI will be applied in a similar manner for each procedure. |
Drug: povidone-iodine topical ointment
Intranasal povidone-iodine will be applied to the lower anterior nares (i.e. nostril) of patients undergoing HELEF orthopedic repair.
Other Names:

| No Intervention: Concurrent Control Standard of Care. This will be usual care at each participating site for subjects enrolled in the Baseline period. |
Outcome Measures
Primary Outcome Measures
- Incidence of Complex (deep incisional or organ space) Staphylococcus aureus surgical site infection (SSI) [within 180 days of the initial surgical procedure for HELEF repair]
Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN) definitions for SSI found in the "Surgical Site Infection Event (SSI)" guide at https://www.cdc.gov/nhsn/pdfs/pscmanual/9pscssicurrent.pdf
Secondary Outcome Measures
- Incidence of all Staphylococcus aureus SSI [within 180 days of the initial surgical procedure for HELEF repair]
Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN) definitions for SSI found in the "Surgical Site Infection Event (SSI)" guide at https://www.cdc.gov/nhsn/pdfs/pscmanual/9pscssicurrent.pdf
- Incidence of all Complex SSI [within 180 days of the initial surgical procedure for HELEF repair]
Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN) definitions for SSI found in the "Surgical Site Infection Event (SSI)" guide at https://www.cdc.gov/nhsn/pdfs/pscmanual/9pscssicurrent.pdf
- Incidence of all gram-negative Complex SSI [within 180 days of the initial surgical procedure for HELEF repair]
Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN) definitions for SSI found in the "Surgical Site Infection Event (SSI)" guide at https://www.cdc.gov/nhsn/pdfs/pscmanual/9pscssicurrent.pdf
- Incidence of cellulitis involving the surgical site [within 180 days of the initial surgical procedure for HELEF repair]
Cellulitis is a common bacterial skin infection that causes redness, swelling, and pain in the infected area of the skin surrounding the surgical site of the HELEF repair.
- Clavien-Dindo assessment of postoperative complications scores [within 180 days of the initial surgical procedure for HELEF repair]
The Clavien-Dindo assessment grades postoperative surgical complications from 1 to 5, with 5 being the worst outcome. Postoperative courses with no evidence of complications have no grade (a "0" for the purposes of this study).
