Preventing wound infections after open colon and small bowel surgery

The DECREASE SSI Trial (Decolonization to Reduce After-Surgery Events of Surgical Site Infection)

NIH-funded research University of California-Irvine · NIH-11093397

This trial tests whether doing chlorhexidine body washes and using a nasal iodophor after you leave the hospital can reduce wound infections in people who had open colon or small bowel surgery.

What this research studies

You would be randomly assigned after your operation to either routine post-discharge wound care or a decolonization plan that adds chlorhexidine bathing and a nasal iodophor. The trial is being done at multiple hospitals and follows patients for 30 days after they go home to track surgical site infections and recovery. Study staff will collect information about infections that occur after discharge, wound healing, and how the care affects your daily life. This post-discharge plan is tested on top of the standard pre- and intra-operative infection prevention steps to see if the extra measures help.

Who could benefit from this research

Good fit: People having open colon or small bowel surgery who will be discharged home and can follow a bathing and nasal decolonization routine are the ideal candidates.

Not a fit: Patients who have minimally invasive (laparoscopic) procedures, cannot use chlorhexidine or iodophor because of allergies, or cannot follow the post-discharge routine may not receive benefit.

Why it matters

Potential benefit: If successful, this low-cost, easy-to-use regimen could lower post-discharge wound infections and improve recovery after these surgeries.

How similar studies have performed: Decolonization with chlorhexidine and nasal antiseptics has reduced infections in some surgical settings, but its benefit specifically as a post-discharge routine for open colon and small bowel surgery is not yet proven.
