Photos and thermal scans to spot wound infections after cesarean births

Image-based algorithms for remote cesarean surgical site infection diagnoses in diverse populations

NIH-funded research Univ of North Carolina Chapel Hill · NIH-11394211

This project will use smartphone photos and thermal images to help community health workers find wound infections after cesarean delivery in women in Rwanda, Ghana, and Mexico.

What this research studies

If you join, researchers will follow about 6,000 women (2,000 at each site) after a cesarean birth and check wounds around 10 days after surgery. Community health workers will collect visible photos and thermal images of the incision and record the clinical diagnosis. The team will see how well two existing image-based tools work across countries and different skin tones and will update the algorithms if needed. The goal is to make it easier for local health workers to identify infections without requiring travel to a clinic.

Who could benefit from this research

Good fit: Women who have recently had a cesarean delivery in the participating sites (Rwanda, Ghana, or Mexico) and can be reached for a follow-up visit around postoperative day 10 are ideal candidates.

Not a fit: People without access to a phone or unable to be contacted for the scheduled follow-up, or whose complications occur outside the follow-up window, may not benefit from this approach.

Why it matters

Potential benefit: If successful, this could help detect wound infections earlier, speed treatment, and reduce travel and costs for new mothers.

How similar studies have performed: Earlier versions of the visible-image algorithm showed about 83% sensitivity and 75% specificity and the thermal-image algorithm showed about 95% sensitivity and 84% specificity, but they need validation in diverse countries and skin tones.
