The Burden of Diabetic Foot Ulcers on Hospital Admissions and Costs in Romania

Background/Objectives: Diabetic foot ulcers represent an important economic burden for healthcare systems worldwide. We aimed to analyze the costs of care for diabetic foot ulcers (DFUs) associated with peripheral neuropathy (DPN) and peripheral arterial disease (PAD) and their trends in a tertiary-care hospital. Methods: We used data from the electronic system of the Emergency Clinical County Hospital Cluj-Napoca, Romania. We included all episodes of hospitalization with a discharge date between 1 January 2015 and the 31 December 2018 and a discharge diagnosis of type 1 or type 2 diabetes, DPN, PAD, and foot ulcers. Results: During the analyzed period, 1094 episodes of hospitalization with type 1 or type 2 diabetes and DFUs were recorded. Of these, 25.9% had neuropathic, 47.1% ischemic, and 16.6% neuroischemic DFUs. The median length of hospital stay was 8.0 days, and the median cost per episode of hospitalization was 810.8 EUR, with no significant variations during the analyzed years. The cost per episode of hospitalization was higher in cases with ischemic DFUs than for other etiologies of foot ulcers for 2015-2017 (p < 0.001). In 2018, the costs for ischemic and neuroischemic DFUs were similar and significantly higher compared to neuropathic ones. Predictors of higher costs per episode of hospitalization included the etiology of the DFUs (β = 0.032, p = 0.034) and the length of hospital stay (β = 0.860, p < 0.001). Conclusions: By analyzing data from a tertiary care hospital, we showed higher costs for the care of persons with ischemic DFU.
