Background: The prevalence of diabetes is estimated to be over 5 million adults in the UK. Diabetic foot care is estimated to cost the NHS ~£1 billion per annum, meaning that diabetic foot ulcers (DFUs) are an increasing topic of discussion. It is estimated that reducing the prevalence of DFUs by a third could save the NHS up to £250 million annually. The Society of Vascular Surgery Wound, Ischaemia, foot Infection (WIfI) stage stratifies the risk of amputation and benefit of revascularisation in patients with threatened lower limbs and has been extensively validated in patients with chronic limb-threatening ischaemia, yet data on cohorts with diabetic foot ulcers in the UK remain scarce. The aim of this project was to compare the WIfI stage with the currently used Site, Ischaemia, Neuropathy, Bacterial infection and Depth (SINBAD) score in order to stratify risk in patients with DFUs. Methods: The electronic case record (ECR) of eligible cases was reviewed retrospectively between February 2016 and March 2018. All patients with a recorded opening toe pressure were included. SINBAD score was taken from an ECR proforma and WIfI stage was calculated from ECR notes. The patients were followed up using electronic case notes. Results: 119 patients with 129 foot wounds were included. WIfI stages predicted time to ulcer healing (p=0.04) whereas the trend for SINBAD severity did not reach significance (p=0.08). WIfI stages correlated with the proportion of patients with any minor/major ipsilateral lower limb amputation at 1 year (p=0.03) and minor amputation at 1 year (p=0.04), whilst SINBAD severity did not (p=0.95 and p=0.90, respectively). Conclusions: WIfI more accurately predicts time to healing than SINBAD severity. WIfI predicted amputation risk at 1 year but SINBAD did not. WIfI more accurately predicts risk of minor amputation.
