Development of a Diabetic Foot Ulcer Database Using Classification and Measurement Techniques in a Brazilian Public Health Setting 1: Postgraduate Program in Integrity of Engineering Materials, University of Brasilia, Brasilia, Brazil; 2: International University Center, UNINTER, Brasília, Brazil; 3: Meinig School of Biomedical Engineering, Cornell University, Ithaca, New York, United States; 4: Postgraduate Program in Biomedical Engineering, University of Brasilia, Brasília, Brazil Diabetic foot ulcers (DFUs) are among the most frequent complications of diabetes mellitus (DM), presenting as chronic wounds with challenging healing processes. Conventional treatments, typically performed in outpatient clinics, often have limited effectiveness and require prolonged periods. As an innovative alternative, the use of latex sheets combined with phototherapy—via the Rapha® device—has shown promising results in tissue regeneration. Accurate assessment of DFUs is crucial for appropriate treatment but is hindered by variability in clinical evaluations. To address this limitation and the lack of robust databases in the literature, this study developed a dedicated database comprising clinical information, measurement data, and manually segmented images from specialized Brazilian diabetic foot outpatient clinics. An adapted invasive measurement protocol was initially tested on a mannequin to standardize weekly procedures. Essential data such as the Texas University classification, wound dimensions, exudate, and borders were collected by experienced nurses. The database integrates both tabular and visual information, supporting future research in automatic classification using machine learning and image processing techniques. Additionally, quantitative analyses of wound progression demonstrate the effectiveness of the Rapha® device and the metrological relevance of the database for clinical applications.
