Abstract
BACKGROUND Diabetic foot ulcer is a major medical, social, and economic problem, and a leading cause of hospitalisations, increased morbidity, and mortality. Despite a rising occurrence, there is a dearth of data on the incidence and its predictors. OBJECTIVE To assess the incidence and predictors of diabetic foot ulcers among patients with diabetes mellitus in a diabetic follow-up clinic in Central Ethiopia. DESIGN Retrospective follow-up study design. PARTICIPANTS A total of 418 newly diagnosed diabetes mellitus patients from 1 January 2012 to 31 December 2022. A computer-generated simple random sampling method was used to select the study participants. Data were collected using a structured data extraction checklist. The collected data were entered into Epi Info V.7.2 and exported to STATA V.14 for analysis. To estimate survival time, the Kaplan-Meier method was used, and the survival difference was tested using a log-rank test. OUTCOME MEASURES The Cox proportional hazard model was fitted to identify the predictors of diabetic foot ulcer development. The strength of the association was estimated using an adjusted hazard ratio (AHR) with a 95% confidence interval (CI), and statistical significance was proclaimed at a p<0.05. RESULT The overall incidence of diabetic foot ulcer was 1.51 cases (95% CI 1.03 to 2.22) per 100 person-years of observation. The cumulative incidence was 6.2% (95% CI 4.1% to 8.6%) over 10 years. The median time of follow-up was 45 months (IQR 21-73). Diastolic blood pressure of 90 mm Hg or above (AHR 2.91, 95% CI 1.25 to 6.77), taking combined medication (AHR 3.24, 95% CI 1.14 to 9.19) and having a peripheral arterial disease (AHR 5.26, 95% CI 1.61 to 17.18) were statistically significant predictors of diabetic foot ulcer development. CONCLUSION The risk of occurrence of diabetic foot ulcer was relatively high. Diastolic blood pressure level, combined medication and peripheral arterial disease were independent predictors of diabetic foot ulcer development. Hence, close monitoring and proper interventions are essential.

Abstract
OBJECTIVE Diabetes prevalence has risen rapidly in Sub-Saharan Africa, but rates of retention in diabetes care are poorly understood. We conducted a systematic review and meta-analysis to determine rates of retention in care of persons with type 2 diabetes. METHODS We searched MEDLINE, Global Health and CINAHL online databases for cohort studies and randomised control trials (RCTs) published up to 12 October 2021, that reported retention in or attrition from care for patients with type 2 diabetes in Sub-Saharan Africa. Retention was defined as persons diagnosed with diabetes who were alive and in care or with a known outcome, while attrition was defined as loss from care. RESULTS From 6559 articles identified, after title and abstract screening, 209 articles underwent full text review. Forty six papers met the inclusion criteria, comprising 22,610 participants. Twenty one articles were of RCTs of which 8 trials had 1 year or more of follow-up and 25 articles were of non-randomised studies of which 19 had 12 months or more of follow-up. A total of 11 studies (5 RCTs and 6 non-randomised) were assessed to be of good quality. Sixteen RCTs were done in secondary or tertiary care settings. Their pooled retention rate (95% CI) was 80% (77%, 84%) in the control arm. Four RCTs had been done in primary care settings and their pooled retention rate (95% CI) was 53% (45%, 62%) in the control arm. The setting of one trial was unclear. For non-randomised studies, retention rates (95% CI) were 68% (62%, 75%) among 19 studies done in secondary and tertiary care settings, and 40% (33%, 49%) among the 6 studies done in primary care settings. CONCLUSION Rates of retention in care of people living with diabetes are poor in primary care research settings.

Incidence and predictor of diabetic foot ulcer and its association with change in fasting blood sugar among diabetes mellitus patients at referral hospitals in Northwest Ethiopia, 2021. PLoS One 2022; 17:e0274754. [PMID: 36227947 PMCID: PMC9560537 DOI: 10.1371/journal.pone.0274754] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Accepted: 09/05/2022] [Indexed: 11/05/2022] Open
Abstract
Background Diabetes mellitus is one of the global public health problems and fasting blood sugar is an important indicator of diabetes management. Uncontrolled diabetes can lead to diabetic foot ulcers, which is a common and disabling complication. The association between fasting blood glucose level and the incidence of diabetic foot ulcers is rarely considered, and knowing its predictors is good for clinical decision-making. Therefore, the aim of this study was to determine the incidence and predictors of diabetic foot ulcers and its association with changes in fasting blood sugar among diabetes mellitus patients at referral hospitals in Northwest Ethiopia. Methods A multicenter retrospective follow-up study was conducted at a referral hospital in Northwest Ethiopia. A total of 539 newly diagnosed DM patients who had follow-up from 2010 to 2020 were selected using a computer-generated simple random sampling technique. Data was entered using Epi-Data 4.6 and analyzed in R software version 4.1. A Cox proportional hazard with a linear mixed effect model was jointly modeled and 95% Cl was used to select significant variables. AIC and BIC were used for model comparison. Result A total of 539 diabetes patients were followed for a total of 28727.53 person-month observations. Overall, 65 (12.1%) patients developed diabetic foot ulcers with incidence rate of 2.26/1000-person month observation with a 95% CI of [1.77, 2.88]. Being rural (AHR = 2.30, 95%CI: [1.23, 4.29]), being a DM patient with Diabetic Neuropathy (AHR = 2.61, 95%CI: [1.12, 6.06]), and having peripheral arterial disease(PAD) (AHR = 2.96, 95%CI: [1.37, 6.40]) were significant predictors of DFU. The time-dependent lagged value of fasting blood sugar change was significantly associated to the incident of DFU (α = 1.85, AHR = 6.35, 95%CI [2.40, 16.79]). Conclusion and recommendation In this study, the incidence of DFU was higher than in previous studies and was influenced by multiple factors like rural residence, having neuropathy, and PAD were significant predictors of the incidence of DFU. In addition, longitudinal changes in fasting blood sugar were associated with an increased risk of DFU. Health professionals and DM patients should give greater attention to the identified risk factors for DFU were recommended.

Abstract
Diabetes related amputations remain a major global problem, with devastating complications. We critically appraised relevant literature to quantify the prevalence of diabetes related amputations in sub-Saharan Africa (SSA). An electronic search was performed using the EMBASE and PubMed databases until 2020. Twenty-four out of 834 studies retrieved were included. The pooled prevalence of diabetic-related amputations was 36.9% (95%CI: 32.9%-40.8%). Complications of diabetes related amputations included infection, anaemia, foot deformity and mortality. The study revealed a substantial contribution of diabetes to the burden of amputations in SSA and suggests the need for further studies to assess how to reduce the incidence of diabetes, reduce the incidence of and or delay the progression of macro and microvascular complications of diabetes in SSA.

Abstract
INTRODUCTION Due to the increasing incidence of diabetes in Zimbabwe, complications such as diabetic foot (DF) are anticipated. Establishing local gaps and needs in DF healthcare is paramount for tailoring management strategies. AIMS To determine the status of DF services in the healthcare system and explore awareness of DF management and practices among registered general nurses (RGNs) in Zimbabwe. METHODS A mixed-methods approach was applied. Thirty-one RGNs from 16 public health facilities in Harare, Zimbabwe attending a DF workshop were administered with a cross-sectional survey instrument and a semi-structured questionnaire. Data collected included presence/absence of DF services and podiatrists in healthcare facilities, healthcare system approaches in DF care and availability of DF training/education programs for RGNs. Analysis was performed using Stata and Nvivo software. RESULTS No respondents reported availability of podiatrists. Only 1 (3%) of RGNs reported DF screening in primary care. Sixty percent (18) did not know or had never screened for DF. The RGNs reported inadequate DF educational programs/modules in primary care settings. CONCLUSION This data highlights a need to improve DF education for RGNs at the frontline of managing PLWD. Understanding the needs for DF services may guide interventions to improve education and awareness programs that are appropriately tailored to local constraints in the health system. The non-communicable diseases director is encouraged to develop DF educational programmes for frontline health care workers.

Abstract
The aim of this study is to investigate the risk factors of diabetic foot ulcer (DFU) in patients with Type 2 diabetes. Baseline characteristics of DFU-free patients with Type 2 diabetes were retrospectively collected and DFU was identified during the follow-up. Incidence of DFU was calculated and cumulative incidence was estimated by Kaplan-Meier method. Cox regression model was used to explore factors associated with DFU. A total of 980 patients were included with a median follow-up time of 28.7 months. 259 (26.4%) patients developed DFU with an incidence rate of 11.3 per 100 person-years. The cumulative incidences of DFU at 1 year and 2 years during the follow-up were 5.4% (95% CI 3.9-6.9%) and 14.1% (95% CI 11.7-16.5%), respectively. Cox regression analysis indicated that factors associated with developing DFU included age (hazard ratio (HR)=1.06, 95% CI 1.05-1.07, per 1-year increase), body mass index (HR=1.05, 95% CI 1.02-1.07), higher level of education (HR=0.77, 95% CI 0.60-0.98), hypertension (HR=1.90, 95% CI 1.47-2.45), hyperlipidemia (HR=2.63, 95% CI 2.02-3.43), coronary heart disease (HR=2.88, 95% CI 2.22-3.75), heart failure (HR=2.47, 95% CI 1.91-3.20), stroke (HR=2.44, 95% CI 1.86-3.19), diabetic retinopathy (HR=1.86, 95% CI 1.40-2.48), diabetic kidney disease (HR=1.89, 95% CI 1.41-2.53), diabetic neuropathy (HR=1.73, 95% CI 1.31-2.30), poor glycemic control (HR=1.13, 95% CI 1.07-1.19, per 1% glycosylated hemoglobin increase), and course of diabetes (HR=1.01, 95% CI 1.00-1.01, per 1-month increase). The results showed a relatively high incidence of DFU, and revealed several baseline characteristics identified as risk factors of developing DFU.

Abstract
BACKGROUND Rapid urbanization and westernization have precipitated dramatic changes in the profile and prevalence of surgical diseases in sub-Saharan Africa. Disease of lifestyle is now common. We aimed to review our experience with lower-limb amputations at our surgical service in South Africa. METHODS A single-center retrospective review of a prospectively collected database was performed of all patients who underwent a lower limb amputation. Inferential and descriptive statistics were performed. Patient demographics, indication, type of amputation, and management were reviewed. The primary outcome was 30-day in-patient mortality rate. RESULTS Over a 5-year period (2013-2018), 348 patients underwent lower limb amputations. The median age was 61.5 years. 53.7% were diabetic and 56.3% were hypertensive. 53.2% had associated peripheral vascular disease and 8% preexisting cardiac disease. 30.7% smoked. Guillotine below-knee amputation was frequently performed (44.5% of amputations). 16.1% of these patients required a further operation. The in-hospital mortality rate was 8%. Underlying renal disease was an independent risk factor for mortality (p = 0.004). CONCLUSION Currently, the most common indications for LLA in South Africa are diabetes mellitus and atherosclerosis. This reflects the changing pattern of disease in the country. There is a major problem with access to health care in rural areas in South Africa with significant delays in getting patients to tertiary units for evaluation by specialists. Foot care and prevention at a primary health care level is also lacking. Global improvements in the healthcare system are needed to improve LLA rates in South Africa.

Abstract
AIM The incidence of a diabetic foot ulcer (DFU) is increasing over the previous decade with an increasing prevalence of diabetes mellitus (DM). Despite the increasing incidence of DFU, there is limited information about the problem in Ethiopia. Hence, this study aimed to investigate the incidence of DFU and its predictors among newly diagnosed DM patients who were on follow-up at Felege Hiwot Referral Hospital. METHODS Institution-based retrospective follow-up study was conducted at Felege Hiwot Referral Hospital among newly diagnosed DM patients from January 1, 2009, to December 31, 2018. A simple random sampling method was used to select 401 study participants from a total of 723 eligible population. Data was entered using Epi-Data version 3.1 and exported to STATA version 14 for analysis. The incidence rate was estimated using person-years of observation and Nelson-Aalen cumulative hazard function, showing the cumulative probability of diabetic foot ulcer, was done. The best model (Gompertz) was selected using the AIC and log-likelihood method. Hazard ratio (HR) with its 95% confidence interval was computed and variables having a p-value less than 0.05 in the multivariable model were considered to be significantly associated with DFU. RESULTS A total of 387 patients were followed retrospectively for a median follow-up time of 95 months. Out of all, 66 (17.05%) patients developed DFU with an incidence rate of 4 cases per 100 person-years of observation. Diabetic nephropathy (adjusted hazard ratio (AHR) = 2.37, 95% CI: 1.33-54.24), diabetic retinopathy (AHR = 5.56, 95% CI: 2.64-11.74), and increased body mass index (AHR = 1.13, 95% CI: 1.01-1.27) were found to increase the hazard of DFU. CONCLUSION The incidence of DFU was relatively high. Diabetic nephropathy, diabetic retinopathy, and body mass index were its significant predictors. Therefore, close monitoring of patients with co-morbidities and increased body mass index should be considered to reduce DFU.
