简要总结
The goal of the clinical trial is to investigate adherence to, and effects of, the Bluedrop Monitoring System (BMS) in high-risk patients with at least one previous diabetic foot ulcer (DFU).
The BMS is a remote thermovisual monitoring system, which allows the condition of the soles of the feet to be remotely monitored for thermal and visual signs of inflammation, both of which may signal the onset of certain conditions, such as diabetic foot ulcers.
It is comprised of the Delta Foot Scanner (DFS) device and its accompanying Sentinel Review Interface (SRI) software.
The Covid-19 pandemic has driven the need for remote patient care where possible. Although this is challenging for people with foot ulcers, prevention is the key. Remote thermovisual monitoring might help reduce recurrent foot ulcers and therefore the number of necessary hospital visits which always puts the patient at increased risk of Covid infection.
详细描述
Despite the introduction of preventative foot care guidelines DFUs have a high re-ulceration rate. In the first 12 months following healing, 30-50% will develop a subsequent DFU and by year 5 this rate increases to 70%. Temperature monitoring has been proposed as a way to reduce this re-ulceration rate but has not been widely adopted.
Based on the existing evidence groups such as the International Working Group on the Diabetic Foot (IWGDF) have recommended temperature monitoring for the prevention of recurrent foot ulcers.
Despite these recommendations the technique has not been widely adopted. This is likely due to a number of factors, but NICE, in their guidance document for the prevention and management of foot ulcers (NG19) states:
"While temperature foot monitoring was found to be the only effective form of augmented self-examination, the intervention tool was felt to be quite difficult to use and required a strongly motivated population to actually perform consistently and fill out the required log books".
Bluedrop Medical have developed a product which leverages the existing evidence on temperature monitoring but builds it into a device which also includes the ability to take photographic images, is easy to use, and can integrate well with the healthcare system.
