Clinical Trial Summary

This study evaluates whether specialist negative pressure dressings reduce the risk of wound infections after operations when compared to conservative dressings, and if one negative pressure dressings works better than another. The study will look at patients who have had an open operation on their bowel and the wound closed at the end of the operation.

Description:

Surgical site infections (SSI) can affect up 41% of patients post-operatively. They are associated with significant healthcare and patient costs, and increased patient morbidity and mortality.

Specialist post operative dressings with negative pressure wound therapy are available, and the WHO do recommended for use in high risk wounds, taking resources into account. However no further recommendations are available.

This study will explore the rate of post-operative wound infections in adult patients undergoing open abdominal surgery on the bowel, and compare the rate of wound infections in these patients in relation to three different dressing types used after their operation. The study aims to determine if any of the dressings used within the study are associated with lower post-operative wound infection rates, and compare the overall costs of using each dressing type, including both direct healthcare costs and societal costs. Finally, it will evaluate participant's quality of life outcomes after open abdominal surgery, specifically relating to their wound.
