Outcomes of a multidisciplinary Diabetic Foot Day Unit

Abstract

ObjectiveTo analyse the main characteristics of patients and the health outcomes obtained and to evaluate the impact of peripheral artery disease (PAD) in patients treated in our multidisciplinary Diabetic Foot Unit. Research design and methodsObservational prospective study. 273 patients from two different populations (with and without PAD – classified according to the presence of distal pulses) treated over a 14-month period in the multidisciplinary Diabetic Foot Unit were included. The data on patient characteristics and outcomes were analysed for the purpose of comparison. For the inference study, a comparison of medians with the non-parametric test for independent samples for the quantitative variables and a χ2 test for the comparison of proportions in qualitative variables were performed. ResultsPatients with PAD ulcers were older (60 (54–67) vs. 64 (75–81), p=0.000) and had a higher macrovascular burden (8.1% vs. 29% for ischaemic heart disease history, p=0.000; 6.7% vs. 18.1% for cerebrovascular disease history, p=0.004). Their Texas Score was higher (p=0.000) and their major amputation rate was higher (1.4% vs. 12.3%, p=0.001). They had less background of previous ulcers (52.6% vs. 26.8%, p=0.000), their episode duration was shorter (4 (0–10) vs. 0 (0–3) weeks, p=0.000), and their proportional need for antibiotic therapy was lower (64.4% vs. 51.4%, p=0.03). ConclusionsThe differences found between ulcers with and without vascular involvement support the need for a different approach and for the inclusion of vascular surgeons on the team. The multidisciplinary care model for diabetic foot patients could be effective and improve health outcomes.
