Negative Pressure Wound Therapy
The Prevena Incision Management System is a 510K cleared device that covers and protects the incision from external infectious sources, while negative pressure removes fluid and infectious material from the surgical incision. The ActiVAC pump (also 510K cleared) may be used in some cases with the Prevena dressings as to achieve the negative pressure.
Conventional Wound Therapy
Sterile bandages and dressings.

SECONDARY outcome

Timeframe: 30 days post-surgery

Each surgical site infection was classified into one of the following categories: superficial incisional, deep incisional, or organ/space (as defined by The American College of Surgeons NSQIP \[National Surgical Quality Improvement Program\] guidelines). The number of infections in each category is reported separately for both treatment arms. Some participants had multiple infections.
