A Cross-Sectional Analytical Pilot Study of Diabetic Foot Ulcer Risk Factors among Adult Patients with Diabetes in Sulaimani Teaching Hospitals

BackgroundDiabetic foot is a serious condition in patients with a long lasting diabetes mellitus. Diabetic foot treated improperly may lead not only to delayed ulceration healing, generalized inflammation, unnecessary surgical intervention, but also to the lower limb amputation. The aim of this study was to compare diabetic foot risk factors in population with type 2 diabetes and risk factors for diabetes in healthy subjects.MethodsThe study included 900 subjects: 145 with diabetic foot, 293 with type 2 diabetes without diabetic foot and 462 healthy controls matched in terms of mean age, gender structure and cardiovascular diseases absence. Study was conducted in Gastroenterology and Metabolic Diseases Department, Medical University of Warsaw, Poland. In statistical analysis a logistic regression model, U Mann-Whitney’s and t-Student test were used.ResultsThe binomial logit models analysis showed that the risk of diabetic foot in patients with type 2 diabetes was decreased by patient’s age (odds ratio [OR] = 0.94; 95% confidence interval [CI]: 0.92-0.96; p = 0.00001) and hyperlipidaemia (OR = 0.54; 95% CI: 0.36-0.81; p = 0.01). In contrast, male gender (OR = 2.83; 95% CI: 1.86-4.28; p = 0.00001) diabetes duration (OR = 1.04; 95% CI: 1.03-1.06; p = 0.0003), weight (OR = 1.04; 95% CI: 1.03-1.06; p = 0.00001), height (OR = 1.08; 95% CI: 1.05-1.11; p = 0.00001) and waist circumference (OR = 1.028; 95% CI: 1.007-1.050; p = 0.006) increase the risk of diabetic foot. The onset of type 2 diabetes in healthy subjects was increased by weight (OR = 1.035; 95% CI: 1.024-1.046; p = 0.00001), WC (OR = 1.075; 95% CI: 1.055-1.096; p = 00001), hip circumference (OR = 1.03; 95% CI: 1.01-1.05; p = 0.005), overweight defined with body mass index (BMI) above 24,9 kg/m2 (OR = 2.49; 95% CI: 1.77-3.51; p = 0.00001) and hyperlipidaemia (OR = 3.53; 95% CI: 2.57-4.84; p = 0.00001).ConclusionsRisk factors for Type 2 diabetes and diabetic foot are only partially common. Study proved that patients who are prone to developing diabetic foot experience different risk factors than patients who are at risk of diabetes. Identification of relationship between diabetic foot and diabetes risk factors in appropriate groups may help clinicians to focus on certain factors in diabetic foot prevention.

The Profile and Associated Risk Factors of Diabetic Foot Disease Among Patients with Type 2 Diabetes Mellitus Seen at Outpatient Clinics in a Tertiary Private Hospital in Manila, Philippines. Background: Diabetic foot disease is a debilitating complication of diabetes mellitus and is a major source of morbidity, mortality, and reduced quality of life. Determining the risk factors of diabetic foot ulcer is important to prevent the devastating consequences among patients with diabetes. This study aims to determine the profile and associated risk factors of diabetic foot disease among patients diagnosed with type 2 diabetes mellitus being seen in private specialty clinics. Methodology: A single center, analytical cross-sectional study was conducted among patients with type 2 diabetes mellitus at outpatient clinics in a tertiary private hospital in the Philippines. Clinical information and laboratory results were obtained during the time of consult; and patients were classified as either low risk, moderate risk, high risk for diabetic foot disease or in active foot disease. Interaction between various risk factors was explored by multivariate analysis. Results: A total of 129 adult patients with diabetes mellitus were evaluated using the Diabetes Foot Screening and Risk Stratification Tool from January to May 2021. The demographic and clinical profile of the study showed that proportion of patients with neuropathy (χ2=60.66, p=0.001), long duration of diabetes (F=5.92, p=0.004), and low estimated glomerular filtration rate (eGFR) (F=3.70, p=0.023) was significantly higher in patients with moderate to high risk for diabetic foot disease. Univariate polynomial logistic regression analyses showed that neuropathy greatly increased the odds of having moderate (OR=115.63, p=0.001) and high risk stratification (OR=166.50, p=0.001). Other factors were also noted to affect the risk stratification for diabetic foot disease such as duration of diabetes (OR=1.09, p=0.004) and hypertension (OR=2.45, p=0.027). On the other hand, normal eGFR (OR=–1.02, p=0.011), left normal ankle brachial pressure index (OR=–4.32, p=0.042), and good glycemic control (OR=–5.41, p=0.050) significantly decrease the likelihood of having high risk stratification for diabetic patients. Conclusion: Those most susceptible to developing high risk for diabetic foot disease were patients with neuropathy, hypertension, and long duration of diabetes. High-risk patients with the given profile should be followed closely in order to prevent complications brought by diabetes.

Prevalence, risk level and risk factors of diabetic foot ulcer among adult individuals with diabetes in the Southeastern Anatolia Region of Turkiye.

Background: The International Diabetes Federation states that India accounts for 1 in 7 of all adults living with diabetes worldwide. Diabetic foot disease is among the most serious complications of diabetes mellitus as it is a source of major suffering and financial burden for the patient, healthcare professionals and the society in general. The leading cause of lower-limb amputations is diabetes and 40%–85% of these are preventable Objective: Assessment of diabetic foot ulcer risk factors according to International Working Group on the Diabetic Foot (IWGDF) consensus. Methodology: A community based cross-sectional study was done in Ernakulam district involving 600 individuals with diabetes mellitus. The study gathered information on sociodemographic factors, anthropometric details and a detailed foot examination was performed with a IWGDF checklist. The collected data were entered into MS Excel, and the analysis was carried out using SPSS 21.0. Results: Mean age of patients in the study was 61.48 yrs±10.24 years.371 patients (61.83%) were females and 229(38.17%) were males.108 patients (18%) had disturbed sense of vibration (128 Hz). 90 patients (15%) had decreased sensitivity to 10-gram monofilaments. Peripheral arterial disease was present in 47 patients (7.83). 20 patients (3.33%) had history of previous ulcer. 11(1.83%) patients had lower extremity amputation.

Background Although risk factors for diabetic foot ulceration have been extensively studied in patients with diabetes in Egypt, there is surprisingly limited evidence among those on chronic hemodialysis (CHD). The study aimed to scrutinize the risk factors for foot ulceration in adult patients with diabetes with end-stage renal disease on hemodialysis in Dakahlia Governorate central hemodialysis units. Patients and methods This cross-sectional study included all diabetic patients under CHD aged more than or equal to 18 years (n=98), recruited over 7 months from the largest seven central hemodialysis units in Dakahlia Governorate, Egypt. Data collection consisted of a participant interview, medical record review, and noninvasive comprehensive foot examination. The assessment included peripheral neuropathy, peripheral arterial disease, other foot pathologies, footwear, and foot health care behavior. Results The study included 57 males and 41 females. The median duration of diabetes was 15 (2–33) years. Overall, 61 (62.2%) patients were on insulin therapy. The median duration of hemodialysis was 3 years. Insensate neuropathy and peripheral arterial disease were detected in 65.3 and 15.3% of patients, respectively. The prevalence of foot deformities was 18.36%. Plantar calluses and dry skin were diagnosed in 27.6 and 62.2% of patients, respectively. A total of two (2.04%) patients had active foot ulcers and nine (9.18%) patients had ulcers in remission; therefore, the overall diabetic foot ulceration prevalence was 11.22%. In addition, 10 (10.2%) patients had previous minor amputations, with no reported major amputations. Overall, 95.92% had poor foot health care behaviors, and 81.63% were using inappropriate footwear. None of the included patients previously used custom-made insoles. Conclusions The key finding of this article suggests a high prevalence of risk factors for foot ulceration among diabetic patients receiving hemodialysis. Diabetic foot screening should be included in the management strategy of those on CHD.

The aim was assessment of diabetic foot ulcer risk factors according to International Working Group on the Diabetic Foot (IWGDF) consensus. All referred patients with diabetes were divided into four groups based on IWGDF criteria (without neuropathy, with neuropathy, neuropathy with deformity or vascular disorders, foot ulcer or amputation history). Mean age of patients was 53.8±10.7 years. Two hundred and sixty nine patients ​(62/6%) were female and 161(37/4%) were male. Twenty three percent had disturbed sense of vibration, 26% had decreased sensitivity to monofilaments and 17% had decreased pain sensation. Ankle brachial index (ABI) was abnormal in 6%. About 7% had history of prior ulcer. Patients were classified into four risk groups according to IWGDF criteria. Two hundred and seventy seven patients (65%) were in group 0, 75(17%) in group 1, 47 (11%) in group 2 and 31 (7%) in group 3. Patients in higher-risk groups had higher age, longer diabetes duration, higher HbA1C and less training (p=0.0001, 0.001, 0.0001, 0.021 respectively). The risk was higher in the presence of retinopathy (p=0.005). Patient's sex, BMI, smoking and nephropathy did not have significant correlation with risk of diabetic foot ulcer. This study showed that increase of age, duration of diabetes and HbA1c, lack of training and presence of retinopathy increases the risk of diabetic foot ulcers.

The prevalence of diabetes mellitus in Manggarai Regency in 2019 is 535 people and some of them have diabetic foot ulcers. Patients with diabetic foot ulcers had a higher risk of falling than others.This study was to determine the risk factors for diabetic foot ulcers and the risk of falls in patients with type 2 diabetes mellitus. A quantitative study using a cross-sectional study was conducted at BLUD RSUD dr. Ben Mboi in April-June 2020 (n = 51).The sampling technique used was purposive sampling with a questionnaire of diabetic foot screening and risk stratification form and Morse scale. Logistic regression results showed that there was a significant relationship between claudication (AOR: 8.409, 95% CI 1.664-42.500, p value 0.010), history of previous diabetic foot ulcers (AOR: 5,680, 95% CI 1,151-28,035, p value 0.033) with diabetic foot ulcers. There was a significant relationship between hypertension (AOR: 0.152, 95% CI 0.028-0.834, p value 0.030), diabetic foot ulcers (AOR: 11.392, 95% CI 1.277-101.651, p value 0.029) with the risk of falling for patients with type 2 diabetes mellitus. Assessment of the risk of diabetic foot ulcers and the risk of falls should be done in patients with diabetes mellitus with or without neuropathy peripheral

Large-scale prospective cohort studies on diabetic foot ulcers risk factor screening in China are limited. Therefore, this prospective cohort study aimed to explore the predictive risk factors for diabetic foot ulcers to provide clinicians with concise and effective clinical indicators for identifying a high-risk diabetic foot and guiding the prevention of diabetic foot ulcers. Patients with diabetes who visited the Department of Endocrinology of Peking University First Hospital from October 2017 to December 2018 were selected as research participants by convenience sampling. A total of 968 patients were included. After enrollment, a dedicated person collected and recorded all baseline data. A dedicated telephone follow-up was conducted every 12-24 months to evaluate whether the endpoint event had occurred. All patients were followed up for an average of 61 (57-71) months, with 95% of them followed up for more than 60 months. According to the occurrence of endpoint events, they were divided into the DFU and non-DFU groups. The data between the two groups were analyzed using independent-sample t-test, Wilcoxon rank sum test, and chi square test. We used univariate and multivariate logistic regression analysis to analyze the factors that affected the occurrence of diabetic foot ulcers. After the 5-year follow-up, the incidence of diabetic foot was 25.83%. Multivariate logistic regression analysis revealed that body mass index (odds ratio: 1.046; 95% confidence interval: 1.001-1.093), abnormal pinprick sensation (odds ratio: 4.138; 95% confidence interval: 1.292-13.255), history of fungal foot infection (odds ratio: 2.287; 95% confidence interval: 1.517-3.448), abnormal 128-Hz tuning fork test (odds ratio: 2.628; 95% confidence interval: 1.098-6.294), and HbA1c≥ 8% (odds ratio: 1.522; 95% confidence interval: 1.014-2.284) were independent predictors of diabetic foot. Our study highlights clinically relevant indicators that may help to prevent the occurrence of diabetic foot and guide timely interventions.

Little prospective research exists on risk factors for diabetic foot ulcer that considers the independent effects of multiple potential etiologic agents. We prospectively studied the effects of diabetes characteristics, foot deformity, behavioral factors, and neurovascular function on foot ulcer risk among 749 diabetic veterans with 1,483 lower limbs. Eligible subjects included all diabetic enrollees of a general internal medicine clinic without foot ulcer, of whom 83% agreed to participate. Baseline assessment included history and lower-limb physical examination, tests for sensory and autonomic neuropathy, and measurements of macro- and microvascular perfusion in the foot. Subjects were followed for the occurrence of a full thickness skin defect on the foot that took > 14 days to heal, with a mean follow-up of 3.7 years. Using stepwise Cox regression analysis, the following factors were independently related to foot ulcer risk: foot insensitivity to the 5.07 monofilament (relative risk [95% CI]) 2.2 (1.5-3.1), past history of amputation 2.8 (1.8-4.3) or foot ulcer 1.6 (1.2-2.3), insulin use 1.6 (1.1-2.2), Charcot deformity 3.5 (1.2-9.9), 15 mmHg higher dorsal foot transcutaneous PO2 0.8 (0.7-0.9), 20 kg higher body weight 1.2 (1.1-1.4), 0.3 higher ankle-arm index 0.8 (0.7-1.0), poor vision 1.9 (1.4-2.6), and 13 mmHg orthostatic blood pressure fall 1.2 (1.1-1.5). Higher ulcer risk was associated with hammer/claw toe deformity and history of laser photocoagulation in certain subgroups. Unrelated to foot ulcer risk in multivariate models were diabetes duration and type, race, smoking status, diabetes education, joint mobility, hallux blood pressure, and other foot deformities. Certain foot deformities, reduced skin oxygenation and foot perfusion, poor vision, greater body mass, and both sensory and autonomic neuropathy independently influence foot ulcer risk, thereby providing support for a multifactorial etiology for diabetic foot ulceration.

Diabetic foot ulcers: treatment overview and cost considerations.

BackgroundDiabetic foot is an underestimated and redoubtable diabetes complication. The aims of our study were to assess diabetic foot ulcer risk factors according to International Working Group on the Diabetic Foot (IWGDF) classification, stratify patients into risk categories and identify factors associated with higher-risk grade.MethodsCross-sectional setting over a period of 07 months, patients were randomly selected from the diabetic outpatients attending our unit of diabetology. Questionnaire and clinical examination were made by the same physician. Patients free of active foot ulcer were included.ResultsAmong 230 patients evaluated, 10 had an active foot ulcer and were excluded. Five patients (2.27%) had a history of foot ulcer and 3(1.36%) had a lower-limb amputation. Sensory neuropathy, as measured by the 5.07(10 g) Semmes-Weinstein monofilament testing, was present in 23.63% of patients, whereas 36.82% had a peripheral arterial disease based on clinical findings, and 43.63% had foot deformities. According to the IWGDF classification, Group 0: 72.72%, Group 1: 5.9%, Group 2: 17.73% and Group 3: 3.63%. After univariate analysis, patients in higher–risk groups were significantly more often female, had higher age and BMI, longer diabetes duration, elevated waist circumference, low school level, retinopathy and hyperkeratosis. Multivariate logistic regression analysis identified 3 significant independent factors associated with high-risk groups: retinopathy (OR = 2.529, CI95 [1.131–5.655], p = 0.024), hyperkeratosis (OR = 2.658, CI95 [1.222–5.783], p = 0.014) and school level (OR = 0.489, CI95 [0.253–9.44], p = 0.033).ConclusionsRisk factors for foot ulceration were rather common in outpatients with diabetes. The screening of patients at risk for foot ulceration should start early, integrated with sustainable patient education.
