Comprehensive Foot Examination And Risk Assessment

Comprehensive Foot Examination And Risk Assessment

A report of the Task Force of the Foot Care Interest Group of the American Diabetes Association, with endorsement by the American Association of Clinical Endocrinologists It is now 10 years since the last technical review on preventative foot care was published (1), which was followed by an American Diabetes Association (ADA) position statement on preventive foot care in diabetes (2). Many studies have been published proposing a range of tests that might usefully identify patients at risk of foot ulceration, creating confusion among practitioners as to which screening tests should be adopted in clinical practice. A task force was therefore assembled by the ADA to address and concisely summarize recent literature in this area and then recommend what should be included in the comprehensive foot exam for adult patients with diabetes. The committee was cochaired by the immediate past and current chairs of the ADA Foot Care Interest Group (A.J.M.B. and D.G.A.), with other panel members representing primary care, orthopedic and vascular surgery, physical therapy, podiatric medicine and surgery, and the American Association of Clinical Endocrinologists. The lifetime risk of a person with diabetes developing a foot ulcer may be as high as 25%, whereas the annual incidence of foot ulcers is ∼2% (3–7). Up to 50% of older patients with type 2 diabetes have one or more risk factors for foot ulceration (3,6). A number of component causes, most importantly peripheral neuropathy, interact to complete the causal pathway to foot ulceration (1,3–5). A list of the principal contributory factors that might result in foot ulcer development is provided in Table 1. The most common triad of causes that interact and ultimately result in ulceration has been identified as neuropathy, deform Continue reading >>

Foot Examination - Checking Your Risk Of Developing A Diabetic Foot Ulcer

Foot Examination If a person already has a diabetic foot ulcer, the danger is clearly there (although sometimes both the patient and the doctor can be fooled because there is no pain). The need for treatment of the ulcer by a multi-disciplinary approach involving doctors, podiatrists and nurses is also well established. It is a different type of challenge to identify the patients before they have actually developed an ulcer so that they can receive appropriate footcare education. Who is at risk of developing a diabetic foot ulcer? In a sense every person with diabetes has increased risk of developing foot ulceration and needs to take precautions to prevent it from occurring. However, some people have very low risk and some people have very high risk. Grading the risk helps the individuals and the health professionals to take appropriate measures without being too relaxed or too strict. This is not only good for the individuals, it also helps to direct valuable health care resources to people who need it. Patients at low risk only need general advice. Patients at high risk need detailed, specific and practical footcare instruction. The overall risk of an individual developing a diabetic foot ulcer is determined by a combination of factors. In general, the risk is higher if: Neuropathy is more severe (because more sensation is lost) Peripheral vascular disease is more severe (because there is less circulation to bring enough oxygen to repair tissue damage) There are coexisting abnormalities of the shape of the foot which make the local effects of neuropathy or vascular disease more severe (because it increases local pressure and callus) The person is unable to practise reasonable self care to maintain general condition of the feet and to prevent trauma (because there are Continue reading >>

The Rational Clinical Examination: Evidence-Based Clinical Diagnosis Simel DL, Rennie D. Simel D.L., Rennie D Eds. David L. Simel, and Drummond Rennie. New York, NY: McGraw-Hill, 2009, Foot problems in patients with diabetes are common, but infections with osteomyelitis are extremely serious as they lead to an increase probability of amputation or death from complications. Among patients with diabetes with foot ulcers, about 15% have osteomyelitis. 1 Diabetic Population in Whom Osteomyelitis Should Be Considered Patients with diabetes may have a peripheral neuropathy that decreases their ability to perceive pain, so all patients with diabetes are at risk for foot ulcers. Thus, frequent self-examination by patients and observation of their feet by their physicians is important. All patients with foot ulcers should be evaluated for osteomyelitis. Assessing the Likelihood of Osteomyelitis The assessment should focus on the physical examination findings and the erythrocyte sedimentation rate ( Table 57-1 ). Ulcer area > 2cm2 or the ability to probe to bone are the findings most suggestive of osteomyelitis. An erythrocyte sedimentation rate 70mm/h is similarly useful for identifying patients more likely to have osteomyelitis. These individual findings work as well, or better, than the clinical gestalt (LR+ 5.5, 95% CI 1.8-17) and an abnormal radiograph (LR+ 2.3, 95% CI 1.6-3.3). Inflammatory signs and swab culture are not useful as the likelihood ratio (LR) con Continue reading >>

Foot ulcers and other peripheral diabetic complications are common, and associated with high levels of morbidity and mortality. Early detection and preventative management leads to fewer lower limb amputations. Introductions, explanation and consent Wash hands Dermatological Assessment Perfusion- pale, or pink and well perfused? Any areas of discolouration Venous- moderate to large size, no pain Arterial- deep, well demarcated, very painful Fungal or ingrown nails Look all over the foot and ankle Look between the toes- deeper lesions may be missed! Look under the heel Vascular Assessment Temperature of foot Symmetry of temperature Neurological Assessment Patients with neurological loss of protective sensation (LOPS) are at increased risk of unrecognised injury, leading to ulceration and additional complications. During all sensory assessments, first display what your sensation will feel like on the sternum, then ask the patient to close their eyes and tell you when they can feel it and if it feels the same on both sides. Microfilament (don't use a neurotip - may cause break in skin that leads to ulceration) Press the monofilament firmly so that the tip bends, for 1-2 seconds. If a discrepancy is found then perform a sensory level test, i.e. keep touching up the leg until the patient can feel it Test on the sole; big toe (L4), little toe (L5), heel (S1) Place a 128 Hz tuning fork on the first joint of the big toe Rest your index finger lightly on the patients first, third, and fifth toes Observe for deformity e.g. hammer toe, claw toe, charcot neuropathy Inspect the patient's shoes for unusual wear patterns Looking for: Symmetry Balance Foot drop or dragging of feet Reflexes Ankle jerk (S1,2) Proprioception This is less well researched in diabetic foot care, and does not Continue reading >>

Diabetic Foot Ulcer Assessment And Treatment: A Pharmacists Guide

Diabetic Foot Ulcer Assessment and Treatment: A Pharmacists Guide University of MississippiSchool of Pharmacy The lifetime incidence of developing a foot ulcer may be as high as 25% for the 24 million Americans with diabetes.1 Ulcers, defined as any breaks in the cutaneous barrier, are the most frequent type of diabetic foot wounds and usually extend through the dermis.2 Foot ulcers can cause substantial morbidity, arising from physical and emotional effects, loss of productivity, and financial expense, as well as increased mortality. Consequences could be dire; a foot ulcer precedes 85% of nontraumatic amputations, and mortality can range from 39% to 80% at 5 years postamputation.3,4 Poor metabolic control plays a role in foot ulcer development, underscoring the importance of reducing hemoglobin A1C (HbA1C) to the American Diabetes Association (ADA) guideline goal of less than 7%.5 Intensive control has reduced neuropathy by 57% in type 1 diabetic patients. Each 1% reduction in HbA1C has decreased microvascular complications by 25% in type 2 diabetes.6,7 Diabetic peripheral neuropathy (DPN) is a major microvascular complication that, along with excessive plantar pressure associated with deformity and trauma, can play a major role in ulcer development. DPN can involve all three types of nerve dysfunction: sensory, autonomic, and motor. Sensory neuropathy results when the patient develops a lack of protective sensation. A painless thermal or mechanical injury occurs and remains undetected. Thus, the classic foot trauma case: A patient with diabetes unknowingly steps on a nail, and the foot becomes infected, which leads to serious complications. Autonomic dysfunction leads to reduced perspiration, which compromises skin integrity. Dry skin can easily develop cracks and f Continue reading >>

The Diabetic Foot Examination: A Positive Step In The Prevention Of Diabetic Foot Ulcers And Amputation

Volume 5, Issue 2 , MarchApril 2013, Pages 73-78 The diabetic foot examination: A positive step in the prevention of diabetic foot ulcers and amputation Author links open overlay panel GeorgeScottDPM, DO, FACOFP Get rights and content This paper proposes to introduce a method of performing the diabetic foot examination through introduction of a modified version of the cardinal techniques of examination (inspection, palpation, peripheral vascular or neurologic assessment, and auscultation), more consistent with the sequence taught in physical diagnosis classes in medical schools. The modified sequence should reduce physician time while improving efficiency and effectiveness, utilizing a physical examination sequence model with which the physicians are familiar and can easily adopt and apply in a consistent manner. Regardless of the technique employed, this paper hopes to remind primary care providers of the importance of incorporating a diabetic foot examination or screening tool as part of their practice.

A Strength of recommendation (SOR) A Good-quality patient-oriented evidence B Inconsistent or limited-quality patient-oriented evidence C Consensus, usual practice, opinion, disease-oriented evidence, case series Foot ulcers and other lower-limb complications secondary to diabetes are common, complex, costly, and associated with increased morbidity and mortality.1-6 Unfortunately, patients often have difficulty recognizing the heightened risk status that accompanies the diagnosis of diabetes, particularly the substantial risk for lower limb complications.7 In addition, loss of protective sensation (LOPS) can render patients unable to recognize damage to their lower extremities, thus creating a cycle of tissue damage and other foot complications. Strong evidence suggests that consistent provision of foot-care services and preventive care can reduce amputations among patients with diabetes.7-9 However, routine foot examination and rapid risk stratification is often difficult to incorporate into busy primary care settings. Data suggest that the diabetic foot is adequately evaluated only 12% to 20% of the time.10 In response to the need for more consistent foot exams, an American Diabetes Association (ADA) task force lead by 2 of the authors of this article (AB and DA) created the Comprehensive Foot Examination and Risk Assessment.5 This set the standard for the detailed investigation of lower limb pathology by a specialist, but was not well suited for other practice settings, including primary care.

Evaluation Of The Diabetic Foot

Evaluation Of The Diabetic Foot

INTRODUCTION Foot problems are an important cause of morbidity in patients with diabetes mellitus. The lifetime risk of a foot ulcer for diabetic patients (type 1 or 2) may be as high as 25 percent [1]. A potentially preventable initiating event, most often minor trauma that causes cutaneous injury, can often be identified. Foot amputations, many of which are preventable with early recognition and therapy, may be required [2]. These observations illustrate the importance of frequent evaluation of the feet in patients with diabetes to identify those at risk for foot ulceration [3]. Systematic screening examinations for neuropathic and vascular involvement of the lower extremities and careful inspection of feet may substantially reduce morbidity from foot problems. Evaluation of the diabetic foot is provided here. A discussion of diabetes-related foot infections (cellulitis and osteomyelitis) and the management of diabetic foot ulcers are found elsewhere. (See "Clinical manifestations, diagnosis, and management of diabetic infections of the lower extremities" and "Management of diabetic foot ulcers".) RISK FACTORS Several risk factors are predictive of ulcers and amputation. Early recognition and management of risk factors is important for reducing morbidity of foot ulceration. Most risk factors are readily identifiable from the history or physical examination. The most important are previous foot ulceration, neuropathy (loss of protective sensation), foot deformity, and vascular disease [1-4]. The significance of these risk factors was confirmed by the results of a community-based study of 1300 type 2 diabetic patients [5]. The incidence of lower extremity amputation was 3.8 per 1000 patient-years. Predictors of amputation were foot ulceration (hazard ratio [HR] 5.6, 95% Continue reading >>

Comprehensive Foot Examination And Risk Assessment

Comprehensive Foot Examination And Risk Assessment

Go to: THE PATHWAY TO FOOT ULCERATION The lifetime risk of a person with diabetes developing a foot ulcer may be as high as 25%, whereas the annual incidence of foot ulcers is ∼2% (3–7). Up to 50% of older patients with type 2 diabetes have one or more risk factors for foot ulceration (3,6). A number of component causes, most importantly peripheral neuropathy, interact to complete the causal pathway to foot ulceration (1,3–5). A list of the principal contributory factors that might result in foot ulcer development is provided in Table 1. The most common triad of causes that interact and ultimately result in ulceration has been identified as neuropathy, deformity, and trauma (5). As identification of those patients at risk of foot problems is the first step in preventing such complications, this report will focus on key components of the foot exam. Go to: COMPONENTS OF THE FOOT EXAM History While history is a pivotal component of risk assessment, a patient cannot be fully assessed for risk factors for foot ulceration based on history alone; a careful foot exam remains the key component of this process. Key components of the history include previous foot ulceration or amputation. Other important assessments in the history (Table 2) include neuropathic or peripheral vascular symptoms (7,8), impaired vision, or renal replacement therapy. Lastly, tobacco use should be recorded, since cigarette smoking is a risk factor not only for vascular disease but also for neuropathy. General inspection A careful inspection of the feet in a well-lit room should always be carried out after the patient has removed shoes and socks. Because inappropriate footwear and foot deformities are common contributory factors in the development of foot ulceration (1,5), the shoes should be inspec Continue reading >>

What you need to know Diabetic foot can be prevented with good glycaemic control, regular foot assessment, appropriate footwear, patient education, and early referral for pre-ulcerative lesions Examine the feet of people with diabetes for any lesions and screen for peripheral neuropathy and peripheral arterial disease, which can lead to injuries or ulceration Refer patients with foot ulceration and signs of infection, sepsis, or ischaemia immediately to a specialised diabetic foot centre for surgical care, revascularisation, and rehabilitation Foot disease affects nearly 6% of people with diabetes1 and includes infection, ulceration, or destruction of tissues of the foot.2 It can impair patients’ quality of life and affect social participation and livelihood.3 Between 0.03% and 1.5% of patients with diabetic foot require an amputation.4 Most amputations start with ulcers and can be prevented with good foot care and screening to assess the risk for foot complications.5 We provide an update on the prevention and initial management of diabetic foot in primary care. Sources and selection criteria This clinical update is based on recommendations in the standard treatment guideline, The diabetic foot: prevention and management in India 2016, published by the Indian Ministry of Health and Family Welfare.33 A multidisciplinary guideline development group consisting of surgeons, primary care practitioners, and a patient representative developed these guidelines, with inputs from experts in diabetes, diabetic foot rehabilitation, and vascular surgery. The group included representation from rural and urban India, and public and private sectors. The guideline development group selected recommendations from the National Institute for Health and Care Excellence clinical guideline 1 Continue reading >>

Author: Vincent Lopez Rowe, MD; Chief Editor: Romesh Khardori, MD, PhD, FACP more... The history should focus on symptoms indicative of possible peripheral neuropathy or peripheral arterial insufficiency. The symptoms of peripheral neuropathy include the following: Symptoms of peripheral arterial insufficiency Most people harboring atherosclerotic disease of the lower extremities are asymptomatic; others develop ischemic symptoms. Some patients attribute ambulatory difficulties to old age and are unaware of the existence of a potentially correctible problem. Patients who are symptomatic may present with intermittent claudication, ischemic pain at rest, nonhealing ulceration of the foot, or frank ischemia of the foot. Cramping or fatigue of major muscle groups in one or both lower extremities that is reproducible upon walking a specific distance suggests intermittent claudication. This symptom increases with ambulation until walking is no longer possible, and it is relieved by resting for several minutes. The onset of claudication may occur sooner with more rapid walking or walking uphill or up stairs. The claudication of infrainguinal occlusive disease typically involves the calf muscles. Discomfort, cramping, or weakness in the calves or feet is particularly common in the diabetic population because they tend to have tibioperoneal atherosclerotic occlusions. Calf muscle atrophy may also occur. Symptoms that occur in the buttocks or thighs suggest aortoiliac occlusive disease. Rest pain is less common in the diabetic population. In some cases, a fissure, ulcer, or other break in the integrity of the skin envelope is the first sign that loss of perfusion has occurred. When a diabetic patient presents with gangrene, it is often the result of infection. Physical examinati Continue reading >>
