Reducing skin tone inequities in chronic venous insufficiency care

Reducing Health Inequities Through Improved Guidance and Assessment on the Early Identification of Skin Changes Associated With Chronic Venous Insufficiency (CVI) in People With Dark Skin Tones

Observational King's College London · NCT06798766

This project will try ways to recognize and document leg skin changes in people with darker skin tones who have chronic venous insufficiency.

What this trial studies

The project has two parts: interviews to map patient journeys and experiences, and clinical photography and skin examinations to record how CVI presents on darker skin. In the first work package researchers will conduct qualitative interviews with people with dark skin tones (Ho & Robinson 2b–6b) and/or their close family to learn how they noticed skin changes and where care could be improved. In the second work package participants with confirmed CVI will undergo standardized skin examination and medical photography to define visual and tactile criteria for diagnosis on darker skin. Findings will inform clinical guidance, training materials, and co-designed interventions to reduce diagnostic delays and inequities in nurse-led assessment pathways.

Who should consider this trial

Good fit: Adults with diagnosed chronic venous insufficiency (or their close family members) who have darker skin tones (Ho & Robinson 2b–6b), can give informed consent, and (for the photography part) can attend the London study sites.

Not a fit: People with lighter skin tones, those unable to consent or speak English, or those unable to travel to the hospital are not eligible and are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, the work could lead to clearer diagnostic signs and better training that reduce delays and inequities in CVI care for people with darker skin.

How similar studies have performed: While prior work has documented skin tone disparities in dermatology and wound care, systematic criteria for recognizing CVI on darker skin are limited, so this approach is relatively novel.
