Introduction: Foot amputation in a diabetic patient is a real public health problem due to its functional and psychological repercussions. The objective was to study the factors associated with amputation in patients monitored for a diabetic foot in the internal medicine hospitalization of the Abass Ndao University Hospital Center (CHU) in Dakar. Methods: This was a retrospective, descriptive and analytical study conducted from the records of hospitalized patients over a 24-month period. The analysis included a descriptive phase, followed by a bivariate phase completed by logistic modeling following a descending procedure. Results: Of 1499 hospitalized patients, 224 cases had diabetic foot (14.9%). Among the cases of diabetic foot, 198 patients met the inclusion criteria. Their mean age was 61.7 ± 11.3 years, the sex ratio (M/F) was 1.2. Other associated cardiovascular risk factors were high blood pressure (54.0% 107 cases), and smoking (10.9% 21 cases). A history of lower limb amputation was found in 21.2% (42 cases). It was type 2 diabetes in 184 cases (92.9%) and the mean blood sugar was 2.7 ± 1.3 g/l. Chronic complications included neuropathy in 112 cases (78.3%), arteriopathy in 172 cases (86.9%), and chronic kidney disease in 167 cases (84.4%). The mean consultation time was 47.6 days. The main lesions were gangrene (64.6%), ulcer (24.7%), phlegmon (5.6%), and necrotizing fasciitis (5.1%). According to the University of Texas classification, patients presented with a stage D lesion (86.4%), grade 3 (51.0%). The hospital prevalence of amputation was 57.6% (114 cases), including major amputation in 55.1% (109 cases). The mortality rate was 36.4% (72 cases). Risk factors for amputation were peripheral arterial disease (ORa = 4.96 [1.33 - 18.43] p = 0.017), foot gangrene (Ora = 3.16 [1.24 - 8.04] p = 0.016) and Texas classification grade 3 (ORa = 17.49 [1.67 - 190] p = 0.019). Conclusion: The prevalence of foot and amputations remains a health problem. Reducing amputations will necessarily require strengthening prevention through education and early monitoring of diabetic patients.
