Remote Temperature and Visual Monitoring to Help Manage Diabetic Foot Ulcers

Not Applicable

Recruiting

• Conditions: Diabetic Foot Ulcer (DFU)

• Registration Number: NCT06782386
• Lead Sponsor: Bluedrop Medical Limited

Brief Summary

This study is a prospective, observational investigation evaluating the effectiveness of Remote ThermoVisual Monitoring (RTVM) in the early detection of diabetic foot ulcers (DFUs) in high-risk populations. The primary objective is to compare the incidence of Wagner stage 2 or higher DFUs at the time of presentation between patients using RTVM and a matched control group from a retrospective patient database.

Participants will include adults aged 18 years or older with type 1 or type 2 diabetes mellitus and a history of a plantar DFU that healed within the past five years. The study will enroll approximately 100 participants across up to 30 centers affiliated with SerenaGroup®. The intervention involves daily use of the OneStep Foot Scanner™, which measures temperature and captures visual images of the soles of the feet to detect signs of inflammation or anomalies.

Secondary objectives include evaluating ulcer-free survival, amputation-free survival, time to first evaluation for new DFUs, and healthcare utilization rates. Exploratory endpoints will assess neuropathy-specific quality of life and the costs associated with ulcer and amputation care. Participants will be monitored over a period of 12 months.

Results from this study aim to provide insights into the efficacy of RTVM as a preventative tool for managing diabetic foot health and reducing the burden of DFUs in high-risk populations.

Detailed Description

This study is a prospective, multicenter, observational investigation designed to assess the utility of Remote ThermoVisual Monitoring (RTVM) using the OneStep Foot Scanner™ in detecting diabetic foot ulcers (DFUs) at an earlier stage in high-risk populations. DFUs represent a significant clinical and economic burden, often leading to severe complications, including infections and amputations. Early detection and intervention are critical to reducing morbidity and improving patient outcomes.

The primary objective is to compare the incidence of Wagner stage 2 or higher DFUs at the time of presentation in participants using RTVM to a matched historical control group. The secondary objectives include ulcer-free survival, amputation-free survival, time to first evaluation for new DFUs, and healthcare utilization rates. Exploratory endpoints include assessing neuropathy-specific quality of life and evaluating the economic impact of RTVM on DFU and amputation care costs.

The study will enroll approximately 100 participants aged 18 years or older with a confirmed diagnosis of type 1 or type 2 diabetes mellitus and a history of plantar DFUs that have healed within the past five years. Eligible participants will be recruited across up to 30 SerenaGroup® clinical sites. Participants will use the OneStep Foot Scanner™ daily to capture thermographic and visual data of the soles of their feet, which will be analyzed to identify signs of inflammation, potential ulceration, or other abnormalities. The data collected will be reviewed periodically by healthcare professionals for signs requiring intervention.

Participants will be followed for a period of 12 months, during which they will undergo regular clinical evaluations and remote monitoring assessments. The study will not only evaluate the effectiveness of RTVM in reducing the severity of DFUs but also explore its impact on healthcare costs, quality of life, and overall disease management strategies.

This study aims to provide critical insights into the feasibility of implementing RTVM as a preventive tool in routine diabetic foot care and its potential role in mitigating the global burden of DFUs.
