Digital Foot Technology in Ulcer Prevention and Reulceration: A Clinical Perspective

Studies have shown that personal and economic reasons determine whether clinicians use diagnostic technology in their routine clinical biomechanical practice. This study aimed to identify the biomechanical management plan of local clinicians in relation to management of the diabetic high-risk foot and to investigate whether diagnostic technology is being used to determine the effectiveness of dispensed prescription orthoses in view of ulcer prevention.

A mixed-methodologic approach was adopted in this study. A retrospective quantitative study was also conducted to access records of patients attending the biomechanics clinic at a local health biomechanics clinic. Outcomes of interest included the number and percentage of patients attending the biomechanics clinic, source of referral to this clinic, age and gender of patients, clinical diagnosis, management plan, and referral pathway. Following a phenomenologic approach, four experienced clinicians working in the private, primary, and tertiary health sectors were interviewed. Thematic analysis was used to analyze and interpret data.

Only low-risk patients living with diabetes mellitus were referred for a comprehensive biomechanical examination; the majority were referred by podiatrists. There was no record of diabetic high-risk patients being referred for a detailed biomechanical assessment within the health service. This study also confirmed that, because of the expenses and laborious work involved when using diagnostic technology to assess foot pressures, interviewed clinicians based their treatment plan and tested the efficiency of dispensed offloading devices on the basis of clinical experience and visual observation only.

Waiting for signs of ulceration can be too late for the high-risk foot. A change in clinical practice is recommended where the integration of diagnostic technology, together with standard care, in view of ulcer prevention is warranted.
