Abstract Aim To assess the usefulness of monthly thermography and standard foot care to reduce diabetic ulcer recurrence. Methods People with diabetes ( n = 110), neuropathy history ≥ 1 participated in a single‐blind multicentre clinical trial. Feet were imaged novel thermal imaging device (Diabetic Foot Ulcer Prevention System). Participants randomized intervention (active + care) or control (blinded followed up until recurrence for 12 months. thermograms participants from group assessed hot spots (areas temperature 2.2°C higher than corresponding contralateral site) acted upon as per local standards. Results After months, 62% ulcer‐free 56% group. The odds ratios (intervention vs control) 0.82 (95% CI 0.38, 1.8; P 0.62) 0.55 0.21, 1.4; 0.22) univariate multivariate logistic regression analyses, respectively. hazard time 0.84 0.45, 1.6; 0.58) 0.67 0.34, 1.3; 0.24) Cox Conclusions Monthly did not result significant reduction rate increased survival this cohort at high risk ulcers. This trial has, however, informed design refined study longer follow‐up stratification, further aiming efficacy
