Risk Factors of Diabetic Foot Amputation in Pakistani Type II Diabetes Individuals

Introduction The major grave outcome of diabetic complications is the amputation of lower limb extremities. Recurrent foot infections, trauma, ischemia, and peripheral neuropathy play a crucial role in predicting foot amputation. The aim of this study is to identify the risk factors of diabetic foot amputations in Pakistani patients. Methods Patients admitted with diabetic foot-related complications were followed throughout their hospital stay. Their sociodemographic and disease-related characteristics were recorded. Patients who were advised foot amputation were taken as group A, and patients who were managed conservatively were termed as group B. Their characteristics were then compared. Results Out of 226 study participants, there were 51 (22.5%) patients in group A who were advised foot amputation. There were more men in group A as compared to group B (72.5% vs. 30.8%; p<0.00001). Group A also had a longer duration of diabetes (15.23 +/- 8.52 years vs. 11.98 +/- 9.69; p=0.03). Group B included more patients taking insulin therapy (44.5% vs. 37.3%; p=0.002). All three risk factors of atherosclerosis-smoking, hyperlipidemia, and hypertension-were significantly associated with group A (p=0.05). This coexistence of diabetic nephropathy and retinopathy were more common in group A (p=0.05). Conclusion The incidence of foot amputation in diabetic patients is high. Crucial risk factors include male gender, smoking, hyperlipidemia, hypertension, cardiac history, and the coexistence of diabetic nephropathy and retinopathy.
