Brief summary
This study is a prospective, multi-center, two-arm, unblinded, and randomized controlled trial with a goal of evaluating the impact of a closed incision negative pressure dressing (PREVENA) on incidence of post-operative wound complications and medical costs in patients undergoing lower extremity amputation.
Detailed description
This is a prospective, multi-center, two-arm, unblinded, randomized controlled trial to evaluate the impact of a closed incision negative pressure dressing (PREVENA™ PEEL & PLACE™ Dressing Kit) on incidence of post-operative wound complications in patients undergoing above-the-knee (AKA) or below-the-knee (BKA) amputation. Up to 440 subjects at approximately five (5) participating sites will be randomized to receive either the Prevena dressing or a standard care dressing. The incision will be assessed for complications at post-op day 5 or day 6 and at approximately 30 days after discharge. The primary outcome of this study is reported wound complications, including dehiscence (opening of the incision), seroma, lymph leak, infection (deep or superficial), hematoma (blood clots), ischemia (decreased blood supply), and necrosis (tissue death) A major complication is defined as any wound complication requiring intravenous or oral antibiotics, reoperation and/or hospital readmission. All data (demographics, medical history, and clinical outcomes) will be collected via medical record review
Interventions
In combination with a negative pressure pump (V.A.C. ® Therapy Unit, KCI USA, Inc.), the Prevena dressing is designed to provide negative pressure wound therapy (NPWT) over surgical incisions (incisional NPWT).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Overall Rate of Wound Complications | 30 days post procedure | Presence of any of the following post-procedure: * Dehiscence (skin or fascia) * Seroma * Lymph leak * Infection (superficial or deep, using CDC Surgical Site Infection criteria) * Hematoma * Ischemia * Necrosis |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Length of Stay (LOS) | 30 days post procedure | index LOS is defined as days from operation to discharge; 30d LOS is defined as the index LOS plus all readmission days within 30d related to any wound complication |
| 30-day Return to Operating Room (ROR) | 30 days post procedure | Reoperation for wound complication within 30 days involving incision and drainage in the operating room; opening the skin to drain a superficial soft tissue infection at bedside or in the office is not considered reoperation |
| 30-day Hospital Readmissions | 30 days post procedure | Rehospitalization for wound complication within 30 days |
| Incidence of Skin Dehiscence | 30 days post procedure | Individual rates of the incidence of skin dehiscence |
| Incidence of Fascial Dehiscence | 30 Days | Individual incidence rate of fascial dehiscence |
| Incidence of Superficial Skin Infection | 30 days | Individual incidence of superficial skin infection |
| Incidence of Deep Skin Infection | 30 days | Individual incidence of deep skin infection |
| Incidence of Seroma | 30 Days | Individual incidence of seroma |
| Incidence of Hematoma | 30 days | Individual Incidence of Hematoma |
| Incidence of Necrosis | 30 Days | Individual incidence of Necrosis |
