Prevention Of Diabetic Foot Ulcer

Diabetic Foot Ulcers: Prevention, Diagnosis And Classification

Diabetic Foot Ulcers: Prevention, Diagnosis And Classification

Diabetic ulcers are the most common foot injuries leading to lower extremity amputation. Family physicians have a pivotal role in the prevention or early diagnosis of diabetic foot complications. Management of the diabetic foot requires a thorough knowledge of the major risk factors for amputation, frequent routine evaluation and meticulous preventive maintenance. The most common risk factors for ulcer formation include diabetic neuropathy, structural foot deformity and peripheral arterial occlusive disease. A careful physical examination, buttressed by monofilament testing for neuropathy and noninvasive testing for arterial insufficiency, can identify patients at risk for foot ulcers and appropriately classify patients who already have ulcers or other diabetic foot complications. Patient education regarding foot hygiene, nail care and proper footwear is crucial to reducing the risk of an injury that can lead to ulcer formation. Adherence to a systematic regimen of diagnosis and classification can improve communication between family physicians and diabetes subspecialists and facilitate appropriate treatment of complications. This team approach may ultimately lead to a reduction in lower extremity amputations related to diabetes. Diabetic foot complications are the most common cause of nontraumatic lower extremity amputations in the industrialized world. The risk of lower extremity amputation is 15 to 46 times higher in diabetics than in persons who do not have diabetes mellitus.1,2 Furthermore, foot complications are the most frequent reason for hospitalization in patients with diabetes, accounting for up to 25 percent of all diabetic admissions in the United States and Great Britain.3–5 The vast majority of diabetic foot complications resulting in amputation begin w Continue reading >>

Cost Effectiveness Of Preventing Diabetic Foot Ulcers

Cost Effectiveness Of Preventing Diabetic Foot Ulcers

Home / Specialties / Podiatry / Cost Effectiveness of Preventing Diabetic Foot Ulcers Cost Effectiveness of Preventing Diabetic Foot Ulcers Does an ounce of prevention beat a pound of cure? According to the ADA, treatment of diabetic foot ulcers (DFUs) along with associated infections, below the knee amputations, and surgeries to revascularize the lower limbs account for a significant portion of the costs incurred in the treatment of diabetes. Yet with the frequency of occurrence of these complications, there are very few studies that drive the paradigm toward either primary prevention (avoiding DFUs entirely) or secondary/tertiary measures (efficient treatment of DFUs in those who are not aware [secondary]/are aware [tertiary] of diabetic ulcers), which are combined into a single term (secondary prevention) for purposes of the article. Sadly, utilization of primary prevention of these complications is spotty in most health care systems, and implementation of secondary prevention is often delayed in patients with DFUs. It is speculated that one reason little attention is paid to these secondary measures may be the concern over a small return on the investment in trying to prevent amputations, an attitude that certainly appears to be both counter-intuitive and counterproductive. An attempt to show otherwise was made by N.R. Barshes et al. who utilized a Markov model demonstrating the probability of significant cost savings attributable to otherwise less costly preventive measures. The idea of the Markov model allows prediction of transition from one condition to another, with the understanding that the probability of any transition is only dependent on the current condition, but not any past condition, and that these conditions exist over a continuum. A simple example w Continue reading >>

[email protected] . Cited by (CrossRef): 9 articles Check for updates Ulceration of the feet, which can result in loss of limbs and even death, is one of the major health problems for people with diabetes mellitus. To assess the effects of patient education on the prevention of foot ulcers in patients with diabetes mellitus. We searched The Cochrane Wounds Group Specialised Register (searched 03 September 2014); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 8). Prospective randomised controlled trials (RCTs) that evaluated educational programmes for preventing foot ulcers in people with diabetes mellitus. Two review authors independently undertook data extraction and assessment of risk of bias. Primary end points were foot ulceration or ulcer recurrence and amputation. Of the 12 RCTs included, the effect of patient education on primary end points was reported in only five. Pooling of outcome data was precluded by marked, mainly clinical, heterogeneity. One of the RCTs showed reduced incidence of foot ulceration (risk ratio (RR) 0.31, 95% confidence interval (CI) 0.14 to 0.66) and amputation (RR 0.33, 95% CI 0.15 to 0.76) during one-year follow-up of diabetes patients at high risk of foot ulceration after a one-hour group education session. However, one similar study, with lower risk of bias, did not confirm this finding (RR amputation 0.98, 95% CI 0.41 to 2.34; RR ulceration 1.00, 95% CI 0.70 to 1.44). Three oth Continue reading >>

8 Daily Habits For Preventing Diabetic Foot Ulcers

8 Daily Habits For Preventing Diabetic Foot Ulcers

If you have diabetes, it is critical that you have regular foot exams, at least every six months, by your doctor or a foot health professional—such as a podiatrist. A foot exam can reveal a lesion that hasn’t healed or may be infected. You may not feel pain, but that doesn’t mean you’re not at risk. Any untreated foot infection increases the risk of amputation. Also, do daily foot inspections yourself. Look and feel for bumps, lumps, blisters or bruises; cuts, sores or cracked skin; patches of thin or shiny skin, which can signal lack of blood flow; tingling or numbness; ingrown toenails with red, puffy skin along the nail and tenderness or pain. Check the bottom of your feet with a hand mirror if you aren’t flexible enough to look at the soles. See a health professional to treat any of these conditions. Follow these additional tips to keep your feet healthy and free of sores and infections: 1. Clean and dry Wash your feet every day with lukewarm water, making sure to dry them thoroughly, especially between and under toes; athlete’s foot or other fungal infections can occur in moist areas of the feet. 2. Fit and trim Trim your toenails regularly or have a foot health professional do it for you. 3. Keep your hands to yourself Don’t cut or file calluses or other protrusions on your feet and don’t use wart removers or other harsh chemicals. 4. Get comfy Have new shoes properly measured and fitted—don’t wear shoes that are too loose or too tight. 5. Search your shoes Check inside shoes daily for sharp points, sharp edges, seams or other rough areas or foreign objects that may lead to cuts, wounds or abrasions. 6. Stay sweat-free Wear padded socks made of acrylic or acrylic blends to protect feet and keep moisture away. 7. Go with the flow Walk as much as Continue reading >>

Treatment Strategies - Diabetic Foot Treatment Treatment Strategies - Diabetic Foot Treatment Innovations in Diabetic Foot Care: Prevention, a report by Sugam Bhatnagar, Manish Bharara and David G Armstrong Southern Arizona Limb Salvage Alliance (SALSA), Department of Surgery, College of Medicine, University of Arizona, Tucson Diabetic foot ulcers and associated wound care methodologies have been the subject of rigorous research during the last decade. Amongst diabetic patients the risk to develop a foot ulcer is estimated to be 15%.1 Lower extremity disease comprising of circulatory or neuropathic origin is twice as likely in diabetics compared to non-diabetics.2 It is important for clinicians to educate themselves on the latest therapies and incorporate them into wound care protocols appropriately and at the most eective time. This editorial reviews innovations in diabetic foot care in the US and provides a guide to the appropriate use of advanced therapies, including debridement, promotion of granulation tissue and wound closure, to help clinicians achieve optimum wound healing. Diabetic foot disease is a progressive condition that is associated with a number of major risk factors. These include neuropathy, peripheral vascular disease and infection, which can lead to poor healing and subsequent amputation. Each risk factor along the disease pathway represents a target for intervention. This approach, coupled with a well-equipped limb salvage team, to identify, treat and manage these targets for intervention, is essential for good quality patient care. Typically, diabetic foot care encompasses treatment as well as prevention strategies. It is recognized that the multidisciplinary team approach involving various specialties, such as Podiatry, Vascular Surgery, Endocri Continue reading >>

Foot Care For People With Diabetes: Prevention Of Complications And Treatment

Foot Care For People With Diabetes: Prevention Of Complications And Treatment

This article for nurses on foot care for people with diabetes is the second in a series of five evidence reviews being written by Sarah Chapman for the British Journal of Community Nursing through 2017. It was published there in April. The prevalence of diabetes, one of the most common chronic conditions in the UK, is increasing. In England, the number of people diagnosed with diabetes rose from 1.9 million in 2006 to 2.9 million in 2013 and this is expected to rise to more than 5 million by 2025. The life expectancy of people with diabetes is shortened by up to 15 years, and 75% die of macrovascular complications (NICE, 2016). Diabetic neuropathy and peripheral arterial disease put people with diabetes at greater risk of foot problems and it is estimated that one in ten will have a foot ulcer due to diabetes during their lives. Diabetes is also the most common cause of limb amputation not associated with trauma, and 80% of these amputations will be preceded by foot ulceration (NICE, 2016). Foot ulcers have a significant impact on people’s quality of life, while the annual cost to the NHS of foot ulcers or amputations was estimated to be around £650 million in 2012, or £1 in every £150. There is considerable regional variation in services and practice for preventing and treating foot problems in people with diabetes, highlighted by NICE in their latest guideline on Diabetic foot problems: prevention and management (NICE, 2016). Evidence-based practice in foot care for people with diabetes Evidence-based practice is the use of current best evidence in making decisions about the care of individual patients combined with clinical expertise and the patient’s preferences and values (Sackett DL et al, 1996).

Prevention And Treatment Of Leg And Foot Ulcers In Diabetes Mellitus

Prevention And Treatment Of Leg And Foot Ulcers In Diabetes Mellitus

Definition An ulcer is defined as a breakdown in the skin that may extend to involve the subcutaneous tissue or even to the level of muscle or bone. These lesions are common, particularly on the lower extremities. Leg and foot ulcers have many causes that may further define their character. Prevalence The prevalence of leg ulceration is approximately 1% to 2%, and is slightly higher in the older adult population.1 Venous ulcers are the most common form of leg ulcers, accounting for almost 80% of all lower extremity ulcerations.2 Peak prevalence is between 60 and 80 years.3 Approximately one third of patients with chronic venous insufficiency will develop venous ulceration before the age of 40 years.2 In addition, venous ulcers may have a prolonged duration and are associated with a high rate of recurrence, which contributes to their prevalence. Ulcerations associated with diabetes are the most common cause of foot ulcers. Most of these ulcers are a direct result of loss of sensation secondary to peripheral neuropathy. Approximately 15% of persons with diabetes will develop foot ulceration during their lifetime.4 Most lower extremity amputations in the United States are preceded by a foot ulcer.5 Arterial ulcers account for 10% to 20% of lower extremity ulcerations. Other causes of lower extremity ulceration are uncommon. Many ulcers may be of mixed cause, with two or more contributing factors leading to ulceration present in the same patient. We focus on the most common causes of ulceration. Pathophysiology Neurotrophic Ulcers The development of neurotrophic foot ulcers in patients with diabetes mellitus has several components, including neuropathy, biomechanical pressure, and vascular supply. Peripheral neuropathy is clearly the dominant factor in the pathogenesis of d Continue reading >>

Combined Strategies To Avoid Foot Ulcers In Patients With Diabetes

Combined Strategies To Avoid Foot Ulcers In Patients With Diabetes

Foot ulcers (open sores) are common in people with diabetes mellitus (type 1 and type 2), especially those with problems in the nerves (peripheral neuropathy), the blood supply to their legs (peripheral vascular disease) or both. People with ulcers due to diabetes will sometimes need an amputation (surgical removal of part of the limb). Foot ulcers not only lead to physical disability and loss of quality of life, but also to economic burden (healthcare costs, industrial disability). The aim is therefore to prevent foot ulcers occurring, for example, by showing patients with diabetes how to look after their feet or by prompting doctors to check their patients' feet more often. The results of single prevention strategies alone have so far been disappointing, therefore in clinical practice, preventive interventions directed at patients, healthcare providers and/or the structure of health care are often combined. In this review of trials of complex, preventive interventions, we found insufficient evidence that these combined approaches can be effective in reducing foot problems. There is no high-quality research evidence evaluating complex interventions for preventing diabetic foot ulceration and insufficient evidence of benefit. Continue reading >>

Diabetes-related Foot Ulcers: Prevention And Treatment

Diabetes-Related Foot Ulcers: Prevention and Treatment By Mindi J. Feilmeier, DPM, FACFAS, and Katherine Frush, DPM, FACFAS Recent studies show approximately 25% of patients with diabetes will develop a foot ulcer within their lifetime; the annual US burden of diabetic foot ulcers is estimated to be at least $15 billion. Routine comprehensive foot examinations and risk assessments are essential to preventing diabetes-related lower extremity complications and formidable foot ulcerations. Diabetes mellitus is a major cause of morbidity and mortality in the United States. According to Centers for Disease Control and Prevention data from 2012, more than 29 million people in the United States have diabetes, and one in four is unaware of the disease's presence. Additionally, another 86 million adults have prediabetes. In 2012, diabetes and its related complications accounted for $245 billion in total medical costs.1 Recent studies show approximately 25% of patients with diabetes will develop a foot ulcer within their lifetime; the annual US burden of diabetic foot ulcers is estimated to be at least $15 billion.2 There is an estimated 3% yearly diabetes mellitus population risk of ulcer, with a 7% yearly risk in diabetes patients with neuropathy, and an estimated 30% to 58% of patients with diabetes will develop neuropathy. Recent data cite that 25% of diabetes-related hospital admissions are for extremity complications. Diabetic lower extremity ulcerations are multifactorial. General risk factors for lower extremity complications in diabetes include being male, having diabetes for more than10 years, poor glycemic control, microalbuminuria, retinopathy, renal disease, increased pulse pressure, age, and tobacco and alcohol use.3-5 The priority risk factors appear to be having Continue reading >>

Preventing Diabetic Foot Ulcer Recurrence In High-risk Patients

Use of temperature monitoring as a self-assessment tool Abstract OBJECTIVE—The purpose of this study was to evaluate the effectiveness of a temperature monitoring instrument to reduce the incidence of foot ulcers in individuals with diabetes who have a high risk for lower extremity complications. RESEARCH DESIGN AND METHODS—In this physician-blinded, randomized, 15-month, multicenter trial, 173 subjects with a previous history of diabetic foot ulceration were assigned to standard therapy, structured foot examination, or enhanced therapy groups. Each group received therapeutic footwear, diabetic foot education, and regular foot care. Subjects in the structured foot examination group performed a structured foot inspection daily and recorded their findings in a logbook. If standard therapy or structured foot examinations identified any foot abnormalities, subjects were instructed to contact the study nurse immediately. Subjects in the enhanced therapy group used an infrared skin thermometer to measure temperatures on six foot sites each day. Temperature differences >4°F (>2.2°C) between left and right corresponding sites triggered patients to contact the study nurse and reduce activity until temperatures normalized. RESULTS—The enhanced therapy group had fewer foot ulcers than the standard therapy and structured foot examination groups (enhanced therapy 8.5 vs. standard therapy 29.3%, P = 0.0046 and enhanced therapy vs. structured foot examination 30.4%, P = 0.0029). Patients in the standard therapy and structured foot examination groups were 4.37 and 4.71 times more likely to develop ulcers than patients in the enhanced therapy group. CONCLUSIONS—Infrared temperature home monitoring, in serving as an “early warning sign,” appears to be a simple and useful ad Continue reading >>

Prevention Of Diabetic Foot Ulceration: New Evidences For An Old Problem

Prevention Of Diabetic Foot Ulceration: New Evidences For An Old Problem

Prevention of diabetic foot ulceration: new evidences for an old problem Diabetic patients have a 15% lifetime risk of developing a foot ulcer and have a 15% risk of developing a lower extremity amputation. Amputation is preceded by non-healing foot wounds in 85% of cases [ 1 ]. The ulcerated diabetic foot may be considered the complication of the peripheral neuropathy (PN) and/or peripheral arterial disease (PAD). Several studies showed that diabetic patients with PN are at risk of foot ulceration and indeed true neuropathic ulceration is found in almost 50% of the patients with a new foot ulcer according to eurodiale [ 2 ]. Those with PAD are at risk of foot amputation and ischemic lesions are found in the other 50% of patients with foot ulceration. However true ischemic ulcers are observed only in 15% of cases. The remaining 35% have both PAD and PN present at the same time: neuroischemic ulcers [ 2 ]. Many factors may be responsible of the appearance of an ulcer in those patients: intrinsic factors related to the progressive appearance of limited joint mobility, soft tissue stiffness, early and persistent windlass mechanism [ 3 ] presence of structural foot deformities as hammer toes, hallux valgus or pes cavus. Metatarsal heads are prominent. This results in increased pressure underneath the metatarsal heads, which will make the plantar forefoot more susceptible to breakdown, also because patients are unaware of this abnormal pressure because of the neuropathy. However, there are also other contributing factors leading to diabetic foot ulcer formation, such as arterial occlusive disease, foot trauma, history of previous amputations, and callus due to the increased plantar pressures caused by abnormal mechanical loading of the foot [ 4 ]. A sequence of events has b Continue reading >>

Preventing Diabetic Foot Ulcers: A 4-pronged Approach

Preventing Diabetic Foot Ulcers: A 4-pronged Approach

Lisa Nhan, DPM,Michael B. Strauss, MD, Stuart S. Miller, MD ABSTRACT: In the first part of this article (November 2013) , we discussed the various precursors and risk factors for diabetic foot ulcers (DFUs)including joint contractures, arthridities, and callus formation, to name a few. In this article, we will summarize a 4-prong approach to preventing DFUs. ___________________________________________________________________________________________________________________________________________________ The adage an ounce of prevention is worth a pound of cure is particularly appropriate when talking about prevention of DFUs. Although the majority of DFUs will eventually heal with off-loading and appropriate wound care, the real measures of successful outcomes are durability and restoration of function. A 4-pronged approach including patient education, foot skin and toenail care, appropriate footwear selection, and proactive surgical interventions are the essential measures for prevention of new and recurrent DFUs (Figure 1). In our experiences with healed DFU, lower limb amputations proximal to the midfoot/hindfoot level have only been required in 5 specific situations: Figure 1. There are 4 essentials for preventing DFU. When fully implemented almost all new andrecurrent foot wounds in patients with diabetes mellitus can be prevented. Prevention starts withpatient education, an important role of the PCP. Foot skin & toenail care and protective footwear(yellow boxes) are defensive measures that should be done for all patients with DM. When theneed arises, proactive surgeries (red box) are indicated and considered an offensive measure. Patients with uncontrollable deformities of the foot. Patients with pernicious collagen vascular diseases. A subset of patients who hav Continue reading >>

Cited by (CrossRef): 4 articles Check for updates Ulceration of the feet, which can lead to the amputation of feet and legs, is a major problem for people with diabetes mellitus, and can cause substantial economic burden. Single preventive strategies have not been shown to reduce the incidence of foot ulceration to a significant extent. Therefore, in clinical practice, preventive interventions directed at patients, healthcare providers and/or the structure of health care are often combined (complex interventions). To assess the effectiveness of complex interventions in the prevention of foot ulcers in people with diabetes mellitus compared with single interventions, usual care or alternative complex interventions.
