Introduction: Diabetic foot infections represent a common and serious complication of diabetes mellitus, with a wide range of clinical presentations. Despite their significance, uncertainties persist regarding their management and impact on Internal Medicine services.

Materials And Methods: A retrospective cohort study was conducted using data from the Registry of Specialized Healthcare Activity (RAE-CMBD) over a five-year period (2018-22). Patients discharged from Internal Medicine with a diagnosis of diabetic foot were included. Demographic, clinical, and activity data were collected, and the cumulative incidence of diabetic foot, in-hospital mortality, need for amputation, and associated costs of hospitalization were analyzed.

Results: 15,402 episodes with a diagnosis of diabetic foot were identified, representing 0.41% of Internal Medicine, which implies an age-adjusted incidence rate of between 2 and 3 cases per 1000 admissions in these services. These patients had a high in-hospital mortality rate (16%) and a significant percentage required amputation (8.25%). Advanced age, the presence of comorbidities, and complications during admission were associated with a higher risk of mortality and amputation. The average cost per admission is over €6000.

Conclusions: Diabetic foot is a pathology with a high impact on Internal Medicine services, both due to the volume of activity and the high mortality and cost generated by this condition.

Background: Diabetic foot ulcers (DFU) are severe complications of diabetes, posing significant health and societal challenges. Accumulation of reactive oxygen species (ROS) and elevated glucose levels are primary factors affecting diabetic wound healing. Achieving effective treatment by reducing ROS alone is challenging, as high glucose levels continuously drive ROS production.
