Critical limb ischaemia may independently predict hospital readmission among patients with diabetic foot ulcer
Critical limb ischaemia independent predictor of hospital readmission among patients with diabetic foot ulcer suggests a new study published in The International Journal of Lower Extremity Wounds
The aim of the current study was to evaluate the rate of readmission in patients affected by diabetes and foot ulcers (DFUs), and causes and outcomes of patients requiring a new hospitalization. The current study is a retrospective observational study including patients who have required hospitalization since January 2019 to September 2022 due to a DFU. Once patients were discharged, they were regularly followed as outpatients. Within 6 months of follow-up, the rate of hospital readmission for a diabetic foot problem was recorded. According to the readmission or not, patients were divided into 2 groups, readmitted and not readmitted patients, respectively. Hence, all patients were followed for 6 months more and outcomes of the 2 groups were analyzed and compared.
Overall, 310 patients were included. The mean age was 68 ± 12 years, the majority of patients reported type 2 diabetes (>90%), and the mean diabetes duration was approximately 20 years. Sixty-eight (21.9%) patients were readmitted. The main reason for hospital readmission was the presence of critical limb ischemia (CLI) in the contralateral limb (6.1%), the recurrence of CLI in the previous treated limb (4.5%), and the onset of new infected DFU in the contralateral foot (4.5%). Readmitted patients reported lower rate of healing (51.5% vs 89.2%, P < .0001) and higher rate of major amputation (10.3% vs 4.5%, P = .2) in comparison to not readmitted patients.
Critical limb ischemia resulted in the only independent predictor of hospital readmission. Hospital readmission is a frequent issue among patients with DFUs, and readmitted patients showed a lower chance of wound healing. Critical limb ischemia resulted in the main cause of new hospitalization.
