Mutonga DM, Mureithi MW, Ngugi NN, et al. Diabetic foot ulcers in a Kenyan referral and teaching hospital: risk factors, patient characteristics and clinical outcomes. Series Endo Diab Met. 2019;1(2):41-51.
Introduction: The burden of diabetes mellitus (DM) is increasing in resource-poor settings leading to a rise in diabetic complications. Foot complications result in almost half of all hospital admissions among diabetic patients and may result in amputations or death.
Objective: To investigate the sociodemographic, clinic-laboratory characteristics and clinical outcomes of patients with diabetic foot ulcers (DFU) in a clinical setting.
Materials and Methods: A cross-sectional study of 84 adult consecutive inpatients and outpatients at Kenyatta National Hospital (KNH) with any type of DM and having active DFU was conducted over 12 months. History and physical examinations findings were recorded through a structured questionnaire. Relevant data on the most recent blood tests and clinical outcomes for patients with foot ulcers were retrieved from the patients’ medical notes and analysed.
Results: Majority (68%) were inpatients. The mean age was 60.30 years with 68% living in urban areas and 60% having minimal or no formal education. 8% were newly diagnosed with DM. The median duration of DM was 6.5 years. A majority (96%) had type 2 diabetes mellitus (T2DM). 45% were on insulin only, 18% on oral drugs only and 32% on a combination of both. The median random blood sugar was 9.60 mmol/L and glycated haemoglobin was 8.80%. Although 61% of patients had co-morbid hypertension, only about 40% had elevated systolic blood pressure (BP) while 23% had elevated diastolic pressures. A majority of the patients had good lipid profile, 85% with desirable total cholesterol and 70% having ideal low-density lipoproteins. The mortality rate among patients with DFU was 11%.
Conclusion: There are poor outcomes for patients with DFU in this setting such as poor wound healing, high recurrence rates, increased amputations and mortality compared to previous studies. However, the prevalence of uncontrolled hypertension, dyslipidaemia and neuropathy was much lower than earlier local reports.
