Abstract

Background The occurrence and complications of diabetes are increasing worldwide. This study examined the prevalence and determinants of diabetic foot ulcers and lower extremity amputations in three selected tertiary hospitals in Ghana. Methods A cross-sectional multicenter study involving 100 subjects was carried out. Subjects were selected through simple random sampling from three selected tertiary hospitals in Ghana. A structured questionnaire was used to document information on sociodemographic, medical history, lifestyle, and physical characteristics of subjects. Foot ulcers and lower extremity amputations were also investigated. Total cholesterol, triglycerides, low-density lipoproteins, high-density lipoproteins, serum urea, serum creatinine, and estimated glomerular filtration rate of subjects were assessed. Data analysis was done using SPSS version 22. Results The study revealed that 31% and 69% were males and females, respectively, with a mean age of 53.8 ± 13.8 years. Among the patients, 11% had diabetic foot ulcers whilst 3% had lower extremity amputations. In the multivariate binary logistic regression analysis, previous history of foot ulcers (OR = 40.4, 95% CI = 5.5-299.9) and foot deformities (OR = 14.4, 95% CI = 1.3-161.2) were identified as independent predictors of diabetic foot ulcers. Foot deformity (p = 0.043) and serum urea (p = 0.002) were associated with diabetic lower extremity amputations in the univariate analysis. Conclusion This study showed that the prevalences of diabetic foot ulcers and lower extremity amputations are high among diabetes patients. Foot deformities and previous history of foot ulcers are determinants of diabetic foot ulcers. Foot deformity and serum urea are associated with diabetic lower extremity amputations.

Highlights

Global prevalence of diabetes is high and still on the rise [1]
Based on the gaps observed above, this study is aimed at defining the extent, the associated risk factors, and predictors of foot ulcers and lower extremity amputations among type 1 and type 2 diabetics in Ghana to help improve preventive strategies to lessen the burden of these diabetes-related complications
A total of 100 diabetes patients were enrolled into the study

Summary

Introduction

Global prevalence of diabetes is high and still on the rise [1]. The prevalences in the world, Africa, and Ghana stand at 8.8%, 3.2%, and 3.6%, respectively [1, 2]. An increase in the prevalence of diabetes is accompanied by an increase in its complications such as foot ulcers and lower extremity amputations, in that, the lifetime risk of a person with diabetes developing a foot ulcer is 25% [3]. This study examined the prevalence and determinants of diabetic foot ulcers and lower extremity amputations in three selected tertiary hospitals in Ghana. 11% had diabetic foot ulcers whilst 3% had lower extremity amputations. Foot deformity (p = 0 043) and serum urea (p = 0 002) were associated with diabetic lower extremity amputations in the univariate analysis. This study showed that the prevalences of diabetic foot ulcers and lower extremity amputations are high among diabetes patients. Foot deformity and serum urea are associated with diabetic lower extremity amputations
