Introduction andObjective. Diabetic foot is a complication of diabetes mellitus (DM) and is the leading cause of lower limb amputation. Use of the application 'Cuidando do Pé' (Caring for the Foot), with the aim of achieving better preventive alternatives and seeking better patient monitoring. Materials and method. Cross-sectional study, carried out with 20 patients with Type II Diabetes Mellitus, in routine consultations between June -November 2022. The collection was performed from a questionnaire made available through the application 'Cuidando do Pé' and the behaviours given accordingly. Results. 40% did not know about foot care; among those who did, 80% had never had their feet evaluated by health professionals, 55% did not perform proper care, and 30% claimed to have chronic pain at the site. None of the patients presented deformities or changes in skin integrity or colour; however, absent pilification (20%), xeroderma (25%), cracks (5%), hypertrophic (5%) or hypotrophic (5%) nails, humid (5%) or macerated (5%) interdigital spaces, decreased superficial (35%) and deep (5%) sensibility, altered reflexes (20%), lower limb oedema (15%), cold temperature (5%), and decreased peripheral pulses (up to 25%) were presented. Conclusion. Most of the patients with type II DM analysed did not perform proper foot care, and many did not know what this care was and were classified, on average, as having moderate risk of developing complications. Several alterations were presented, most of which could be avoided with routine consultations and more information on comorbidities associated with type II DM. The application 'Cuidando do Pé' is a viable alternative for better standardisation of care, also having simplicity and accessibility for health workers.
