Factors associated with diabetic foot among type 2 diabetes in Northern area of Saudi Arabia: a descriptive study

Two-year incidence and risk factors of diabetic foot ulcer: second phase report of Ahvaz diabetic foot cohort (ADFC) study

AIM/INTRODUCTION

This study was designed as the second phase of a prospective cohort study to evaluate the incidence and risk factors of diabetic foot ulcers (DFU).

MATERIALS AND METHODS

The study was conducted in a university hospital in Iran. Each participant was checked and followed up for two years in terms of developing newfound DFU as ultimate outcome. We investigated the variables using univariate analysis and then by backward elimination multiple logistic regression.

RESULTS

We followed up 901 eligible patients with diabetes for two years. The mean age of the participants was 53.24 ± 11.46 years, and 58.53% of them were female. The two-year cumulative incidence of diabetic foot ulcer was 8% (95% CI 0.071, 0.089) [Incidence rate: 49.9 /1000 person-years]. However, the second-year incidence which was coincident with the COVID-19 pandemic was higher than the first-year incidence (4.18% and 1.8%, respectively). Based on our analysis, the following variables were the main risk factors for DFU incidence: former history of DFU or amputation [OR = 76.5, 95% CI(33.45,174.97), P value < 0.001], ill-fitting foot-wear [OR = 10.38, 95% CI(4.47,24.12), P value < 0.001], smoking [OR = 3.87,95%CI(1.28, 11.71),P value = 0.016], lack of preventive foot care [OR = 2.91%CI(1.02,8.29),P value = 0.045], and insufficient physical activity[OR = 2.25,95% CI(0.95,5.35),P value = 0.066].

CONCLUSION

Overall, the two-year cumulative incidence of diabetic foot ulcer was 8% [Incidence rate: 49.9 /1000 person-years]; however, the second-year incidence was higher than the first-year incidence which was coincident with the COVID-19 pandemic (4.18% and 1.8%, respectively). Independent risk factors of DFU occurrence were prior history of DFU or amputation, ill-fitting footwear, smoking, lack of preventive foot care, and insufficient physical activity.

Comparison of vitamin D levels in diabetes mellitus patients with and without diabetic foot ulcers: An analytical observational study in Jakarta, Indonesia

Diabetic foot ulcer (DFU) is a form of chronic wound which becomes a serious complication in diabetes mellitus (DM). Recently, the role of vitamin D on T cell-mediated immunity, pancreatic insulin secretion, and its mechanism on cell growth and healing processes have been reported. This study aims to compare the vitamin D level of DM patients with DFU and without DFU to assess the duration and severity of DFU and its correlation with vitamin D levels. The sociodemographic characteristics and DFU duration were documented. The severity was examined in accordance with PEDIS classification. 25-hydroxyvitamin D (25[OH]D) was analysed using in-vitro chemiluminescent immunoassay (CLIA). Statistical analysis was performed and the P-value <.05 was considered as statistically significant. The vitamin D levels in DM patients with and without DFU were 8.90 ng/mL (6.52-10.90) and 16.25 ng/mL (13-19.59), respectively, with P < .001. There was no correlation between the duration of DFU and DFU severity by PEDIS score with vitamin D levels. Vitamin D levels in DM patients with DFU are lower than those in patients without DFU. However, there was insufficient evidence to conclude that there is no correlation between the DFU duration and DFU severity by PEDIS score with vitamin D levels.

Prediction of Foot Ulcers Using Artificial Intelligence for Diabetic Patients at Cairo University Hospital, Egypt

Introduction

In Egypt, diabetic foot ulcers markedly contribute to the morbidity and mortality of diabetic patients. Accurately predicting the risk of diabetic foot ulcers could dramatically reduce the enormous burden of amputation.

Objective

The aim of this study is to design an artificial intelligence-based artificial neural network and decision tree algorithms for the prediction of diabetic foot ulcers.

Methods

A case-control study design was utilized to fulfill the aim of this study. The study was conducted at the National Institute of Diabetes and Endocrine Glands, Cairo University Hospital, Egypt. A purposive sample of 200 patients was included. The tool developed and used by the researchers was a structured interview questionnaire including three parts: Part I: demographic characteristics; Part II: medical data; and Part III: in vivo measurements. Artificial intelligence methods were used to achieve the aim of this study.

Results

The researchers used 19 significant attributes based on medical history and foot images that affect diabetic foot ulcers and then proposed two classifiers to predict the foot ulcer: a feedforward neural network and a decision tree. Finally, the researchers compared the results between the two classifiers, and the experimental results showed that the proposed artificial neural network outperformed a decision tree, achieving an accuracy of 97% in the automated prediction of diabetic foot ulcers.

Conclusion

Artificial intelligence methods can be used to predict diabetic foot ulcers with high accuracy. The proposed technique utilizes two methods to predict the foot ulcer; after evaluating the two methods, the artificial neural network showed a higher improvement in performance than the decision tree algorithm. It is recommended that diabetic outpatient clinics develop health education and follow-up programs to prevent complications from diabetes.

A Systematic Review of Chronic Diseases and Their Prevalence Among the Population of Northern Borders Province (NBP) in Saudi Arabia

Estimation of the prevalence of chronic conditions is pivotal to effective healthcare planning and management. Therefore, our objective was to systemically review previous literature about the prevalence of chronic diseases among residents of Northern Borders Province (NBP) in Saudi Arabia. The electronic search has been done using scientific databases (PubMed, Ebsco, SciFinder, and Web of Science) and search engines up to September 2021. The following main key terms: chronic disease OR chronic conditions AND prevalence AND Northern Borders Province OR Northern Borders AND Saudi Arabia were applied. Other related terms with a more specific search were done with names of the main cities in the province and the most common diseases in Saudi Arabia. Duplicates were removed electronically by Endnote and manually. Extracted data were tabulated in the literature matrix. The risk of bias and quality of included studies were assessed using the "Strengthening the Reporting of Observational Studies in Epidemiology" (STROBE) checklist. Out of 63 observational studies that were assessed for eligibility, 21 observational studies were included to synthesize the evidence. These studies were conducted on Arar (n=16), Turaif (n=2), and Rafha (n=1), while the remaining were national studies in which NBP was one of the included regions (n=2). The most frequently studied diseases were diabetes (4 records), psychological diseases (4 records), and obesity (3 records). The most prevalent disease was gastroesophageal reflux disease (GERD), with an estimated prevalence of 61% among adults in Arar city. In conclusion, although some research is conducted about chronic diseases somewhere in NBP, further studies are needed to study chronic diseases using a representative sample of the whole NBP population.

Risk assessment of amputation in patients with diabetic foot

The prevalence of diabetes has increased dramatically over the past decade, especially in developing countries, reaching pandemic proportions. Although has been the most important factor influencing the prevalence of type 2 diabetes, the prevalence of type 2 diabetes is on the increase among younger adults. The subsequent rate of increase with age is variable, which is more evident in societies where the general prevalence of the disease is higher. Based on clinical and statistical data obtained from the patients who were admitted to The First and Second Surgery Wards in the Sibiu County Emergency University Clinical Hospital (Sibiu, Romania) and the Proctoven Clinic (Sibiu, Romania) between January 2018 and December 2020, the present study attempted to devise a risk score that can be applied for the benefit of patients. The ultimate aim was that this risk score may be eventually applied by diabetologists and surgeons to assess the risk of amputation in patients with diabetic foot lesions. An important part in the therapeutic management of diabetic foot injuries is the assessment of risk factors. Using this risk score system devised, the risk factors that were found to exert influence in aggravating diabetic foot injuries are smoking, obesity, dyslipidaemia, unbalanced diabetes mellitus (glycated haemoglobin ≥7.5%), duration of diabetes >5 years, hepatic steatosis and the co-existence of various heart diseases. To conclude, all these risk factors aforementioned can decrease the effectiveness of treatment and can have a significant impact on the quality of life, if they are not well known.

Risk categorisation of patients attending a diabetic foot screening clinic in Suez

Objective:

To identify risk factors and assess diabetic foot ulcer (DFU) and amputation risk category (according to the 2015 International Working Group on the Diabetic Foot (IWGDF) guidance) among patients with type 2 diabetes in the Suez governorate, Egypt.

Method:

A cross-sectional study was conducted in the diabetic foot screening clinic of Suez General Hospital. A comprehensive sample of patients with type 2 diabetes attending the diabetes clinic every Saturday were enrolled in the study. Patients were divided into four groups according to their history and foot examination: without neuropathy (Group 0); with neuropathy (Group 1); with neuropathy associated with deformity and/or vascular disorders (Group 2); and with foot ulcer or amputation history (Group 3).

Results:

A total of 220 patients were included in the study. Mean age of participants was 54.6±10.3 years and 70.5% of patients were female. The patients were divided into four groups: 37.3% were in group 0; 37.7% in group 1; 11.8% were in group 2; and 13.2% were in group 3. Male sex and diabetic complications (particularly neuropathy, cardiovascular disease and retinopathy) had the most significant effect on risk classification.

Conclusion:

This study showed that 62.7% of patients with diabetes enrolled in the study were at risk of developing a DFU and amputation. Physicians should conduct a foot assessment and risk categorisation for all patients with diabetes as early management or referral could prevent further complications.

Predictors of Foot Ulcers Among Diabetic Patients at a Tertiary Care Center, Egypt

BACKGROUND AND PURPOSE

Diabetic foot ulcers (DFUs) markedly contribute to morbidity and mortality of diabetic patients. Hence, this study was conducted to investigate the predictors of foot ulcers among Egyptian diabetic patients.

METHODS

A case-control study was conducted among 488 diabetic patients attending the inpatient departments and outpatient clinics at the National Diabetes Institute in Egypt. A pretested data collection sheet was designed to collect and record the following: socio-demographic data, diabetic history and lifestyle characteristics, recorded comorbidities, and the results of foot examination.

RESULTS

Significant positive predictors of DFUs on multivariate logistic regression analysis included presence of three or more comorbidities; two or more diabetic complications; callus; and flatfoot. Significant protective (negative) predictors were management of diabetes by diet, oral hypoglycemic drugs (OHGs), and insulin; and intact vibration sense.

CONCLUSION

Significant positive predictors of DFUs on multivariate analysis were presence of three or more comorbidities, two or more diabetic complications, callus and flatfoot, while protective predictors were management of diabetes by diet, OHGs, and insulin; and intact vibration sense. Hence, close monitoring should be provided to diabetic patients with comorbidities and complications to reduce the risk of DFUs.

Risk factors of diabetic foot ulcer in patients with type 2 diabetes: a retrospective cohort study

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.

Knowledge, Practice and Attitude towards Foot Ulcers and Foot Care among Adults Living with Diabetes in Tobago: A Qualitative Study

Globally, the prevalence of diabetes has risen significantly by 62% over the last ten years. A complication of unmanaged diabetes is diabetic foot ulcer (DFU), which adversely affects the quality of life of individuals with diabetes and inflicts a huge economic burden on the family, government, and health care services. However, this complication is preventable with adequate patient knowledge and practice regarding DFU and foot care. The present study was aimed at assessing the knowledge, attitude, and practice of adults with diabetes on foot ulcers and foot care in Tobago using a qualitative exploratory design. Purposeful sampling technique was used to recruit 20 participants from the lifestyle and diabetes foot clinics of Scarborough Health Centre, Tobago. Telephone interviews were conducted with the use of a semi-structured interview guide. The data obtained from participants were analyzed using thematic content analysis. Four major themes, namely foot ulcer problems, participants’ knowledge on DFU, knowledge on foot care, and practice and attitude of foot care, emerged from the study. The findings from the study revealed that the majority of participants had poor knowledge regarding DFU but exhibited awareness about foot care, especially on foot cleaning and inspection, preventing irritation after washing, appropriate footwear, and not walking barefooted. The participants had good attitudes and practices of foot care despite their poor knowledge of DFU. However, participants reported inadequate health education on DFU and foot care from healthcare personnel. There should be improved health education, information, and communication on DFU and foot care centred and tailored to the understanding of people living with diabetes. This will prevent DFU and reduce the mortality arising from this complication, which is a major target of the sustainable development goals (SDG) in mitigating the burden of non-communicable diseases (NCD) such as diabetes.

Association of glycaemic status and outcomes in diabetic foot problems: a retrospective evidence from South India

OBJECTIVES

Emerging shreds of evidence indicates that the risk of diabetic foot ulcer and associated morbidity can be reduced through the intensive glycemic control. There are very few studies which assessed the effects of glycemic control on diabetic foot problems among Indian patients. We aimed to assess the effect of glycemic control on the outcomes of diabetic foot problems among adult type 2 diabetes (T2DM) patients with foot ulcers.

METHODS

A cross sectional study was conducted among the T2DM patients from a tertiary care teaching hospital in South India. The demographic characters, risk factors, treatment characters, glycemic status were collected among the patients and analyzed against the outcomes of diabetic foot ulcers by reviewing their medical records. Descriptive statistics were used to present the data. The Chi-square test and ANOVA were used for was used for the categorical variables and continuous parameters to identify the factors affecting the outcomes, respectively. All analysis was performed in SPSS v21.

RESULTS

Out of the 100 participants included in the study, 70% were male. The majority (78%) were from an age group of 40 to 70 years, and the mean age was found to be 59.91 ± 10.6 years. The mean duration of diabetes was 9.66 years. Only ankle-brachial Index score (p=0.001) was significantly associated with the type of ulcers, whereas other factors not (p>0.05). A high level of average HbA_1c, BMI, ABI index and poor glycemic status was associated with a significant debridement strategy and longer duration of hospitalization; however, it was not substantial.

CONCLUSION

Our study inferred that poor glycemic status is associated with a significant debridement strategy and longer duration of hospitalization. However, these findings need to be strengthened with adequately powered prospective studies.

Health related quality of life (HRQoL) and its associated surgical factors in diabetes foot ulcer patients

Aim. To evaluate the health-related quality of life (HRQOL) in DFU patients and its association with different surgical parameters in a tertiary care teaching hospital. Methodology. A total of 70 DFU patients from surgery department were enrolled and their demographic details, surgical examination and treatment related parameter were recorded. HRQOL was evaluated using Cardiff Wound Impact Questionnaire. Association of different surgical parameters as predictors of HRQOL was statistically evaluated. Results. Mean age of the study patients was 53.92 ± 9.27 with male preponderance and male: female ratio of 1.5:1. All the patients in the study suffered from type 2 diabetes and mean duration of the diabetes was 8.0±1.4 year. Mean BMI of the study patients was 23.36 ±1.4. All patients of DFU showed deteriorated HRQOL with mean score of 42.2±15.13 in social domain, 17.12±7.43 in wellbeing, 75.33±27.06 in physical domain and total score of 146.56±45.46. Increasing age, female gender, increased BMI, alcohol addiction found to be significantly associated with the deteriorated quality of life with respect to all four major domains which include Social life (P<0.001), wellbeing (P<0.07), physical symptoms (P<0.001) and Overall Quality of life (P<0.001). Surgical parameters like treatment for ulcer, regular follow up, larger size of ulcer, more than one ulcer, and ulcer on planter surface and chronic and recurrent ulcer significantly affect social domain, wellbeing and physical symptoms and total score (p<0.05). Control of blood sugar levels with non-pharmacological measures, OHA or insulin significantly improve Qol (p<0.05). Conclusions. Surgical parameters like site, size, number and duration of ulcer, treatment and blood sugar control significantly affect Qol. Multidisciplinary approach with holistic view is required for management of DFU patients for better quality of life.

Knowledge of diabetic foot care management among medical students at King Abdulaziz University Hospital, Jeddah, Saudi Arabia

OBJECTIVES

To evaluate medical students' knowledge of diabetic foot care management and its related factors.

METHODS

This was a cross-sectional, descriptive study of 303 students studying at King Abdulaziz University Hospital, Jeddah, Saudi Arabia conducted from June to July 2019. Data were collected using a two-part questionnaire. The first one captured student information; the second assessed student knowledge. It consists of 68 true and false questions divided into 4 subscales (risk factors, foot examination, foot complications and footwear selection). The higher the total score is, the higher the students' knowledge.

RESULTS

The total average knowledge score was 55.5±5.5 out of 68. While the mean score was 14.11/16 for risk factors, 9.24/10 for foot examination, 24.21/32 for foot complications, and 7.88/10 for footwear selection subscales. Only 56.4% of students educated diabetic patients about diabetic foot risks;concurrently, only 63% performed foot examinations in diabetes patients. Students who educated diabetic patients, preformed foot exam, or attended extra elective clinical rotation in a diabetic foot team, had a significantly higher knowledge level. Conclusion: Students were found to have high level of knowledge regarding diabetic foot management. Students who educated patients about diabetic foot risk, performed foot examination on patients and students who took elective rotations in a diabetic foot care team had a higher knowledge level.

Clinical, Pathological and Microbiological Evaluation of Diabetic Foot Syndrome

Background and objectives: Diabetic foot ulcer (DFU) is one of the serious complications of diabetes, being related to frequent and long-term hospitalisation, reduced quality of life of the patient, amputations, a high rate of morbidity and mortality. The bacterial aetiology is complex, sometimes involving more than one pathogen, playing a major role in the infection prognosis and development of microbial resistance. This study evaluated the current state of the aetiology, clinical and pathological characteristics of DFU in a single diabetes centre in order to provide some specific measures to prevent it. Materials and Methods: This retrospective study was conducted on patients with diabetes mellitus (252 individuals diagnosed with DFU) between January 2018–December 2019. All participants were assessed based on their clinical characteristics, including complications of diabetes and pathological and microbiological evaluations. Results: The present research revealed that diabetic foot ulcer prevalence was higher in males than in females and higher in type 2 diabetic patients than in type 1 diabetic patients. The patients with diabetic foot ulcer were older, had a higher body mass index (BMI), longer diabetic duration and had more diabetic complications, such as retinopathy, diabetic polyneuropathy and diabetic kidney disease, than patients without diabetic foot ulceration. Conclusions: Taking into account all factors involved, including the aetiology and the antibiotic susceptibility pattern of these isolates, planning the suitable treatment options of patients is possible.

Incidence of Diabetic Foot Ulcer and Its Predictors Among Diabetes Mellitus Patients at Felege Hiwot Referral Hospital, Bahir Dar, Northwest Ethiopia: A Retrospective Follow-Up Study

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.

Impaired quality of life and diabetic foot disease in Saudi patients with type 2 diabetes: A cross-sectional analysis

Objectives:

This study aimed to assess the overall health-related quality of life in type 2 diabetes mellitus patients with diabetic foot disease compared to diabetic patients without diabetic foot and to identify the clinical utility of this assessment.

Methods:

A total of 250 consecutive patients with type 2 diabetes mellitus (100/150 with/without diabetic foot, respectively) were interviewed. The questionnaires of the 36-item short-form survey and region-specific foot and ankle ability measure were applied. Wagner–Meggitt wound classification was used for foot-ulcer evaluation. Follow-up of patients for 3–6 weeks was done to identify the potential clinical short outcomes of diabetic foot ulcers.

Results:

Type 2 diabetes mellitus patients with diabetic foot exhibited poor mental and physical health consequences. Females had more prevalence of forefoot lesions, larger ulcer size, advanced Wagner grade, and higher frequency of unhealed ulcers. Receiver operating characteristic curve analysis demonstrated high value of foot and ankle ability measure and 36-item short-form questionnaires to discriminate type 2 diabetes mellitus patients with and without diabetic foot at cutoff values of 66 and 49.6, respectively. Foot and ankle ability measure questionnaire also showed high performance for differentiating the clinical outcome of foot ulcer. Total foot and ankle ability measure subscale score above the cutoff value of 65.5 could discriminate patients with complete healing and unhealed ulcer lesions at a high sensitivity and specificity.

Conclusion:

The current findings confirm the impact of diabetic foot disease on type 2 diabetes mellitus overall health-related quality of life reflected in 36-item short-form questionnaire and foot and ankle ability measure questionnaire which showed high discriminative values for type 2 diabetes mellitus patient sub-grouping. Their application in routine clinical health assessment with continuous medical education programs is highly recommended to achieve a better health-related quality of life.
