MUSC MUSTCOOL: Prevent Ulcer Recurrence
Monitoring and Managing Newly Healed Chronic Leg and Foot Ulcer Skin Temperature: A Cooling Intervention (MUSTCOOL) to Prevent Ulcer Recurrence
The goal of this study is to test MUSTCOOL, a home-based self-monitoring and self-management ulcer prevention intervention for patients with newly healed chronic venous leg and diabetic foot ulcers. Almost 90% of ulcers recur within 3 months of healing. During the six-month randomized clinic trial, skin temperature will be monitored daily, a maintenance dose of cooling gel pack or placebo will be applied three times weekly to the affected skin, and a bolus dose of cooling will be applied for 5 consecutive days if skin temperature becomes elevated. Outcomes on the incidence of leg ulcer recurrence, pain, physical activity and quality of life will be measured.
