A majority of lower extremities neuro-ischaemic wounds (NIU) are related to:(a) only diabetes (DM); (b) only peripheral artery disease (PAD); (c) co-existing diabetes and peripheral artery disease (DM-PAD). This study aims to characterise the major clinical outcomes of forementioned three groups of lower extremity wound patients in Singapore. Patients hospitalised for lower extremity NIU between January 2014 and October 2017 in a tertiary hospital in Singapore were analysed. Patients' major limb amputation and mortality were assessed using Cox regression models. Cumulative survival and amputationfree survival among the three classified groups were calculated using Kaplan-Meier analysis. Compared with patients with only DM, those in the PAD group and the DM-PAD group had higher risk of major limb amputation (adjusted hazard ratio: 2.47, 95% CI: 1.65-3.70; adjusted hazard ratio: 2.01, 95% CI: 1.53-2.65 respectively) and mortality (adjusted hazard ratio: 2.36, 95% CI: 1.57-3.55; adjusted hazard ratio: 2.46, 95% CI: 1.86-3.26 respectively). The 3-year survival and amputation-free survival were lowest in the DM-PAD group (52.1% and 41.5% respectively), followed by the PAD group (53.3% and 44.6% respectively) and the DM group (74.2% and 68.5% respectively). Lower extremity NIU patients with PAD or DM-PAD were found to have poorer clinical prognosis than those with DM only.
