Remote Temperature Monitoring in Diabetic Foot Ulcer Detection.

Introduction: Diabetic foot ulcers (DFUs) are associated with increased morbidity, mortality, and resource utilization. Remote temperature monitoring (RTM) is an evidence-based and recommended component of standard preventative foot care for high-risk populations that can detect the inflammation preceding and accompanying DFUs.

Objective: This case series illustrates the use of a RTM foot mat for the early detection and prevention of DFUs in patients with a history of DFUs.

Materials And Methods: Three patients with a history of diabetes, neuropathy, and DFUs were provided a RTM foot mat and instructed in its daily use. Persistent localized temperature differences exceeding 1.75˚C between the left and right feet prompted the clinical staff to call the patient to collect subjective history for further triage.

Results: Each patient presented with persistent temperature differences exceeding 1.75˚C. In one case, the patient was instructed to offload, and during a subsequent clinical exam, a callus was debrided and accommodative insoles were issued, resulting in resolution of the temperature differences. In the other 2 cases, the RTM foot mat prompted communication with and examination of the patient when there was damaged tissue deep to callus, resulting in early detection and treatment of uninfected DFUs.

Conclusions: The findings of this case series are consistent with literature supporting the use of RTM for high-risk patients.
