Predictors of lower limb amputations in patients with diabetic foot ulcers presenting to a tertiary care hospital of Pakistan.

To assess the risk factors for lower limb amputations in diabetic patients presenting with foot ulcers.The analytical cross-sectional study was conducted at the Mayo Hospital, Lahore, Pakistan, from December 1, 2019, to May 31, 2020, and comprised patients of either gender having type 1 or type 2 diabetes and foot ulcers. The wounds were assessed according to Wagner wound staging and wound sepsis was evaluated in terms of local infection of the wound, leucocytosis and osteomyelitis of the bone. The glycaemic control of these patients was assessed on presentation by measuring glycated haemoglobin levels. Data was analysed using SPSS 26.Of the 135 patients, 82(60.7%) were males and 53(39.2%) were females. Majority patients 59(43.7%) were aged 50-60 years. All 135(100%) patients underwent some type of amputation. Of all the amputations, 91(67.4%) were done in patients with poor glycaemic control on presentation, and 56(41.5%) in those with stage 4 wound. Local wound infection, increased total leukocyte count and bone showing features of osteomyelitis were significantly associated with increased risk of lower extremity amputations (p<0.05).With proper glycaemic control and early presentation and treatment, majority of amputations could be avoided in diabetic patients with foot ulcers.
