• Little information exists about diabetic foot infections (DFIs) in older patients. We hypothesize that older patients with DFIs have different clinical features and worse outcomes than younger patients. We conducted a prospective observational study consisting of a cohort of patients with diabetes and moderate to severe DFIs. Patients included in the cohort were dichotomized into two groups using percentile 75 (P75) of age as the cut-off value. Patients aged > P75 presented with more comorbidities and foot-related complications, a higher rate of peripheral arterial disease (PAD), worse renal function (higher values of blood urea nitrogen and creatinine, and lower values of estimated glomerular filtration rate), and lower values of HbA1c compared with younger patients. Infection severity, microbiological features, and inflammatory markers were similar in both groups. In the multivariate analysis, minor amputations were associated with age > P75 (OR = 2.8, 95% CI 1.3–5.9, p <0.01), necrosis (OR = 4.2, 95% CI 1.8–10.1, p < 0.01), and CRP values (OR = 1.045, 95% CI 1.018–1.073, p < 0.01). Major amputations were associated with a history of amputation (OR = 4.7, 95% CI 1.3–16.7, p = 0.01), PAD (OR = 4.3, 95% CI 1.2–14.6, p = 0.01), and albumin values (OR = 0.344, 95% CI 0.130–0.913, p = 0.03). In conclusion, limb salvage can be achieved in older patients with diabetes-related foot infections at the same rate as in younger patients, despite the fact that they have more comorbidities and foot-related complications, a higher rate of PAD, and worse renal function.
