Assessment of Risk Factors Leading to Amputation Among Diabetic Septic Foot Patients in Khartoum, Sudan

Introduction  Diabetes is a rapidly growing global health concern, with the World Health Organization (WHO) estimating that 300 million adults will have diabetes by 2025. This chronic condition is associated with complications, including nephropathy, retinopathy, neuropathy, cardiovascular disease, and diabetic foot ulcers (DFUs), which can lead to amputation. Diabetic septic foot (DSF), a severe form of diabetic foot disease, is defined by the WHO as the presence of infection, ulceration, or tissue destruction in the lower limb, often accompanied by neurological abnormalities, peripheral vascular disease, and metabolic complications of diabetes. In Sudan, the incidence of lower limb amputations due to DSF is increasing, with various healthcare centers employing different management strategies, making it challenging to identify which factors are most strongly linked to the highest rates of amputations. This study aims to identify the key risk factors contributing to amputations in patients with diabetic foot syndrome (DFS) in Khartoum, Sudan. Specifically, it seeks to assess the common risk factors for amputation in diabetic septic foot patients at hospital wards and dressing centers in Khartoum State, Sudan. Objectives include identifying risk factors associated with amputations, determining the types and frequency of amputations, and evaluating diabetes control and foot self-care practices.  Methods This was a descriptive cross-sectional study that was conducted anonymously between 01/11/2017 and 08/11/2017 in various hospital wards and dressing centers in Khartoum, Sudan, on 46 diabetic septic foot patients. Data was collected using an interview questionnaire and checklist administered to the attending patients. Quantitative data was analyzed using IBM Corp. Released 2011. IBM SPSS Statistics for Windows, Version 20.0. Armonk, NY: IBM Corp. This paper aims to explore the pathophysiology, risk factors, and clinical management of diabetic foot complications, with a focus on preventing the devastating outcome of amputation.  Results The findings revealed that the most significant risk factors for amputation included a raised HbA1c level (74%), male gender (78%), age over 50 years (96%), and a history of preceding non-healing ulcers (93.5%). Other factors, such as smoking, diabetes-related comorbidities, and the type of diabetes management, showed no significant association with amputation. Normal saline and iodine were the most commonly used wound care solutions (52%). Regarding foot care habits, the most frequently practiced measures among patients included wearing special diabetic shoes (63%), avoiding walking barefoot (63%), and refraining from smoking (59%). Conclusions This study identified key risk factors for amputations in diabetic septic foot (DSF) patients, including elevated HbA1C levels, male gender, age over 50, and a history of unhealing ulcers, with poor foot care practices contributing to higher amputation rates. The findings highlight the importance of glycemic control, foot hygiene, and patient education in preventing amputations. Additionally, the study underscores the need for comprehensive management strategies that address both metabolic control and foot care, particularly in resource-limited settings. These insights can guide local healthcare policies focused on prevention, early intervention, and better resource allocation to reduce diabetes-related complications and improve patient outcomes.
