It costs $1,400 to cover the oozing sore on the diabetic's foot with a piece of artificial skin, helping it heal if patients keep pressure off that spot. So when Medicare paid for the treatment but not the extra $100 for a simple walking cast to protect it, an artificial skin maker last year started giving free casts to some needy patients.
Without the right cushioning, "the person will walk to the bus stop and destroy it," fumes Dr. David G. Armstrong of the Southern Arizona Limb Salvage Alliance.
Limb-salvage experts say many of the 80,000-plus amputations of toes, feet and lower legs that diabetics undergo each year are preventable if only patients got the right care for their feet. Yet they're frustrated that so few do until they're already on what's called the stairway to amputation, suffering escalating foot problems because of a combination of ignorance -- among patients and doctors -- and payment hassles.
"There's no magic medicine right now for the diabetic foot," says specialist Dr. Lawrence Lavery of Texas A&M University, who bemoans that simple-but-effective preventive care just isn't attention-getting.
"People come in (saying), 'Hey, my wife noticed a bloody trail today as I was walking across the linoleum in the kitchen. What should I do?'"
President Barack Obama got a drubbing from surgeons this month after a confusing comment about how they're paid for foot amputations that cost $30,000 or more. That tab is the total cost, including hospitalization; surgeon fees range from about $750 to $1,000.
Obama's larger argument: Better payment for early-stage diabetes treatment, or even care to prevent diabetes, could save the nation money.
The money part's hard to prove but it's a lot of misery saved if it's your foot, and the spat highlights a huge problem. Some 24 million Americans have diabetes, meaning their bodies can't properly regulate blood sugar, or glucose. Over years, high glucose levels gradually damage blood vessels and nerves.
One vicious result: About 600,000 diabetics get foot ulcers every year. Poor blood flow in the lower legs makes those ulcers slow to heal. And loss of sensation in the feet, called neuropathy, makes patients slow to notice even small wounds that rapidly can turn gangrenous.
A mere nick while clipping nails, or a blister from an ill-fitting shoe, can begin the march toward amputation -- and about half of patients who do lose a foot die within five years.
Saving those feet isn't cheap. Treating a slow-to-heal diabetic foot ulcer can cost up to $8,000. If it gets infected, $17,000. Worse, a fraction of patients gets multiple slow-to-heal ulcers each year.
What helps?
--Routine foot checkups. There's great variability in how insurers pay for foot screenings before someone's deemed at high risk, says Dr. Harry Goldsmith, a consultant on podiatric reimbursement. Yet some simple tests, like one that measures blood pressure at the ankle to predict circulation clogs, can signal later risk of ulcers. Medicare patients who do develop certain risk factors qualify for the next step, regular clinic visits to have a technician trim nails or smooth calluses, time that should include a quick check for any wounds, Goldsmith says.
--Gadgets like $20 telescoping mirrors let diabetics who can't move well check their numb soles for wounds between doctor visits, and infrared foot thermometers that cost up to $100 can detect changes in temperature that mean an ulcer's brewing before the skin breaks. Again, insurance payment varies.
--Taking pressure off the foot is key, starting with supportive shoes or insoles that target weak spots before an ulcer strikes. Medicare will help pay for certain therapeutic shoes although paperwork limits the diabetics who try them, says Lavery. He finds that an athletic shoe checked by a foot specialist for proper fit can help many patients.
When an ulcer demands more advanced care like grafting that artificial skin, Armstrong says removable walking casts -- to-the-calf Velcro boots that injured athletes often wear -- ease pressure best but seldom are covered. Worried that doctors wouldn't prescribe its wound healer Dermagraft if patients crushed it before it could work, Tennessee-based Advanced BioHealing has provided nearly 1,900 of the boots through a patient-assistance program since last year, said vice president Dean Tozer.
--The "toe and flow" approach, diabetic limb-salvage teams that pair specialists who otherwise seldom work side-by-side, like podiatrists and vascular surgeons. Wound care won't work well until clogged leg arteries are cleared to improve blood flow, notes Armstrong, whose team at the University of Arizona, Tucson, documented a drop in amputations in its first nine months. Such teams can eliminate some of the time diabetics wait for appointments to treat a festering foot, plus stress prevention.

Chronic Critical Limb Ischemia
Chronic critical limb ischemia is manifested by pain at rest, non-healing wounds and gangrene. Ischemic rest pain is typically described as a burning pain in the arch or distal foot that occurs while the patient is recumbent but is relieved when the patient returns to a position in which the feet are dependent. Objective hemodynamic parameters that support the diagnosis of critical limb ischemia include an ankle-brachial index of 0.4 or less, an ankle systolic pressure of 50 mm Hg or less, or a toe systolic pressure of 30 mm Hg or less. Intervention may include conservative therapy, revascularization or amputation. Progressive gangrene, rapidly enlarging wounds or continuous ischemic rest pain can signify a threat to the limb and suggest the need for revascularization in patients without prohibitive operative risks. Bypass grafts are usually required because of the multilevel and distal nature of the arterial narrowing in critical limb ischemia. Patients with diabetes are more likely than other patients to have distal disease that is less amenable to bypass grafting. Compared with amputation, revascularization is more cost-effective and is associated with better perioperative morbidity and mortality. Limb preservation should be the goal in most patients with critical limb ischemia.
Atherosclerosis underlies most peripheral arterial disease. Narrowed vessels that cannot supply sufficient blood flow to exercising leg muscles may cause claudication, which is brought on by exercise and relieved by rest. (For a review of the diagnosis and management of claudication, see the article by Santilli, et al., in the March 1996 issue of American Family Physician.1) As vessel narrowing increases, critical limb ischemia can develop when the blood flow does not meet the metabolic demands of tissue at rest. While critical limb ischemia may be due to an acute condition such as an embolus or thrombosis, most cases are the progressive result of a chronic condition, most commonly atherosclerosis.

An ankle systolic pressure of 50 mm Hg or less or a toe systolic pressure of 30 mm Hg or less suggests the presence of critical limb ischemia.

Chronic critical limb ischemia is defined not only by the clinical presentation but also by an objective measurement of impaired blood flow. Criteria for diagnosis include either one of the following (1) more than two weeks of recurrent foot pain at rest that requires regular use of analgesics and is associated with an ankle systolic pressure of 50 mm Hg or less, or a toe systolic pressure of 30 mm Hg or less, or (2) a nonhealing wound or gangrene of the foot or toes, with similar hemodynamic measurements.2 The hemodynamic parameters may be less reliable in patients with diabetes because arterial wall calcification can impair compression by a blood pressure cuff and produce systolic pressure measurements that are greater than the actual levels.
Risk Factors:
Chronic critical limb ischemia is the end result of arterial occlusive disease, most commonly atherosclerosis. In addition to atherosclerosis in association with hypertension, hypercholesterolemia, cigarette smoking and diabetes,3,4 less frequent causes of chronic critical limb ischemia include Buerger's disease, or thromboangiitis obliterans, and some forms of arteritis.5
Figure 1a
FIGURE 1A. Right heel ulcer in a 56-year-old patient with diabetes. The ulcer failed to heal after three months of conservative treatment.
Diabetes is a particularly important risk factor because it is frequently associated with severe peripheral arterial disease. Atherosclerosis develops at a younger age in patients with diabetes and progresses rapidly. Moreover, atherosclerosis affects more distal vessels in patients with diabetes; the profunda femoris, popliteal and tibial arteries are frequently affected, while the aorta and iliac arteries are minimally narrowed. These distal lesions are less amenable to revascularization. Atherosclerosis in distal arteries in combination with diabetic neuropathy contributes to the higher rates of limb loss in diabetic patients compared with nondiabetic patients.6,7
Clinical Presentation:
The development of chronic critical limb ischemia usually requires multiple sites of arterial obstruction that severely reduce blood flow to the tissues.7,8 Critical tissue ischemia is manifested clinically as rest pain, nonhealing wounds (because of the increased metabolic requirements of wound healing) or tissue necrosis (gangrene).
Ischemic rest pain is classically described as a burning pain in the ball of the foot and toes that is worse at night when the patient is in bed. The pain is exacerbated by the recumbent position because of the loss of gravity-assisted flow to the foot. Ischemic rest pain is located in the foot, where tissue is farthest from the heart and distal to the arterial occlusions.1 Patients with ischemic rest pain often need to dangle their legs over the side of the bed or sleep in a recliner to regain gravity-augmented blood flow and relieve the pain. Patients who keep their legs in a dependent position for comfort often present with considerable edema of the feet and ankles.
Non-healing wounds are usually found in areas of foot trauma caused by improperly fitting shoes or an injury. A wound is generally considered to be nonhealing if it fails to respond to a four- to 12-week trial of conservative therapy such as regular dressing changes, avoidance of trauma, treatment of infection and debridement of necrotic tissue.
Gangrene is usually found on the toes. It develops when the blood supply is so low that spontaneous necrosis occurs in the most poorly perfused tissues.
Diagnosis:
Patients with diabetes develop atherosclerotic lesions in the more distal leg vessels, which are less amenable to revascularization.
{short description of image}
The presence of rest pain can sometimes be difficult to discern in patients with other chronic leg pain, such as that caused by peripheral neuropathy. Labeling a wound as non-healing can also be a subjective assessment. However, a number of physical findings and objective hemodynamic parameters can be used to substantiate a diagnosis of chronic critical limb ischemia. Typical physical findings include absent or diminished pedal pulses, shiny smooth skin of the feet and legs, and muscle wasting of the calves.
An objective measurement of blood flow is easily accomplished with the use of a hand-held Doppler probe and a blood pressure cuff.1 The cuff is inflated until the pulse distal to the cuff is no longer heard by Doppler. The cuff is then slowly deflated until the pulse is again detected. This measurement is recorded as the systolic pressure. As previously mentioned, an ankle systolic pressure of 50 mm Hg or less or a toe systolic pressure of 30 mm Hg or less suggests the presence of critical limb ischemia.

Peripheral Arterial Disease
Your arteries carry blood rich in oxygen and nutrients from your heart to the rest of your body. When the arteries in your legs become blocked, your legs do not receive enough blood or oxygen, and you may have a condition called peripheral artery disease (PAD), sometimes called leg artery disease.
PAD can cause discomfort or pain when you walk. The pain can occur in your hips, buttocks, thighs, knees, shins, or upper feet. Leg artery disease is considered a type of peripheral arterial disease because it affects the arteries, blood vessels that carry blood away from your heart to your limbs. You are more likely to develop PAD as you age. One in 3 people age 70 or older has PAD. Smoking or having diabetes increases your chances of developing the disease sooner.
The aorta is the largest artery in your body, and it carries blood pumped out of your heart to the rest of your body. Just beneath your belly button in your abdomen, the aorta splits into the two iliac arteries, which carry blood into each leg. When the iliac arteries reach your groin, they split again to become the femoral arteries. Many smaller arteries branch from your femoral arteries to take blood down to your toes.
Your arteries are normally smooth and unobstructed on the inside but, as you age, they can become blocked through a process called atherosclerosis, which means hardening of the arteries. As you age, a sticky substance called plaque can build up in the walls of your arteries. Plaque is made up of cholesterol, calcium, and fibrous tissue. As more plaque builds up, your arteries narrow and stiffen. Eventually, enough plaque builds up to reduce blood flow to your leg arteries. When this happens, your leg does not receive the oxygen it needs. Physicians call this leg artery disease. You may feel well and still have leg artery disease or sometimes similar blockages in other arteries, such as those leading to the heart or brain. It is important to treat this disease not only because it may place you at a greater risk for limb loss but also for having a heart attack or stroke.
What are the symptoms?
You may not feel any symptoms from peripheral artery disease at first. The most common early symptom is intermittent claudication (IC). IC is discomfort or pain in your legs that happens when you walk and goes away when you rest. You may not always feel pain; instead you may feel a tightness, heaviness, cramping, or weakness in your leg with activity. IC often occurs more quickly if you walk uphill or up a flight of stairs. Over time, you may begin to feel IC at shorter walking distances. Only about 50 percent of the people with leg artery disease have blockages severe enough to experience IC.
Critical limb ischemia is a symptom that you may experience if you have advanced peripheral artery disease. This occurs when your legs do not get enough oxygen even when you are resting. With critical limb ischemia, you may experience pain in your feet or in your toes even when you are not walking.
In severe peripheral artery disease, you may develop painful sores on your toes or feet. If the circulation in your leg does not improve, these ulcers can start as dry, gray, or black sores, and eventually become dead tissue (called gangrene).
Amputation:
In extreme cases, especially if your leg has gangrene and is not salvageable, your surgeon may recommend amputating your lower leg or foot. Amputation is a treatment of last resort. Vascular surgeons usually only perform it when the circulation in your leg is severely reduced and cannot be improved by the methods discussed already. More than 90 percent of patients with gangrene who are seen by vascular specialists can avoid amputation or have it limited to a small portion of the foot or toes.

Amputation and diabetes: How to protect your feet
Foot care is especially important if you have diabetes. Diabetes can impair blood flow to your feet and cause nerve damage. Without proper attention and care, a small injury can develop into an open sore (ulcer) that can be difficult to treat. Sometimes amputation is necessary if an infection severely damages the tissue and bone.
The good news is that with proper diabetes management and careful foot care, amputation may be preventable. Here's what you need to know about the link between amputation and diabetes — and how to keep your feet healthy.
Why does diabetes pose a risk of amputation?
Diabetes can cause two potentially dangerous threats to your feet.
* Nerve damage (diabetic neuropathy). When the network of nerves in your feet is damaged the sensation of pain in your feet is reduced. Because of this, you can develop a blister or cut your foot without realizing it.
* Reduced blood flow. Diabetes can also narrow your arteries, reducing blood flow to your feet. With less blood to nourish tissues in your feet, it's harder for sores to heal. An unnoticed cut or sore hidden beneath your socks and shoes can quickly develop into a larger problem.
Left untreated, a minor foot injury could become a serious infection — even leading to tissue death (gangrene). Severe damage might require toe, foot or even leg amputation.

The diabetic foot: amputations are preventable
People with diabetes are at risk of nerve damage (neuropathy) and problems with the blood supply to their feet (ischaemia). Both neuropathy and ischaemia can lead to foot ulcers and slow-healing wounds which, if they get infected, may result in amputation.
In 2000 the International Diabetes Federation endorsed the International Working on the Diabetic Foot as a Consultative Section on the Diabetic Foot. Together the organizations established goals for the future of diabetic foot care worldwide.
Goals
* to inform people of the extent of diabetic foot problems worldwide
* to raise awareness of the diabetic foot among those at risk and those in a position to take action
* to persuade healthcare decision makers that action is both possible and affordable
* to warn healthcare decision makers of the consequences of not taking action
* to inform people with diabetes of the measures they can take to prevent foot complications
Diabetes is a serious chronic disease. In 2003 the global prevalence of diabetes was estimated at 194 million. This figure is predicted to reach 333 million by 2025 as a consequence of longer life expectancy, sedentary lifestyle and changing dietary patterns. This rise is likely to bring a proportional increase in the numbers of people with diabetes complications, including problems of the foot.
Most amputations begin with a foot ulcer
Diabetic foot ulcers as a result of neuropathy or ischaemia are common. In developed countries, up to five per cent of people with diabetes have foot ulcers, and one in every six people with diabetes will have an ulcer during their lifetime. Foot problems are the most common cause of admission to hospital for people with diabetes. In developing countries, foot problems related to diabetes are thought to be even more common. Without action, global amputations rates will continue to rise.
Every 30 seconds a leg is lost to diabetes somewhere in the world
Extensive epidemiological surveys have indicated that between 40% and 70% of all lower extremity amputations are related to diabetes. This means that every 30 seconds a lower limb is lost to diabetes. The vast majority (85%) of all diabetes-related amputations are preceded by foot ulcers.
For most people who have lost a leg, life will never return to normal. Amputation may involve life-long dependence upon the help of others, inability to work and much misery. Aggressive management of the diabetic foot can prevent amputations in most cases. Even when amputation takes place, the remaining leg and the person’s life can be saved by good follow-up care from a multidisciplinary foot team.
In developed countries diabetic foot care accounts for up to 20% of total healthcare resources available for diabetes. In developing countries, it has been estimated that foot problems may account for as much as 40% of the resources available. In western countries, the economic cost of a diabetic foot ulcer is thought to be between US$7,000 and US$10,000. Where healing is complicated and amputation required, this cost may increase to as much as US$65,000 per person.
Up to 85% of amputations can be prevented
In most cases, however, diabetic foot ulcers and amputations can be prevented. Researchers have established that between 49% and 85% of all amputations can be prevented. It is imperative, therefore, that healthcare professionals, policymakers and diabetes representative organizations undertake concerted action to ensure that diabetic foot care is structured as effectively as local resources will allow. This will facilitate improvements in foot care for people with diabetes throughout the world and bring about a reduction in diabetic-foot-related morbidity and mortality.
Significant reductions in amputations can be achieved by well-organized diabetic foot care teams, good diabetes control and well-informed self care
There is strong evidence to indicate that foot care is best delivered when it is provided by a multidisciplinary team. This should closely involve the person with diabetes and his or her family, along with healthcare professionals from different specialties. Ideally the team will include a physician, a nurse, a specialist educator, a podiatrist, a surgeon, an orthotist (shoemaker) and an administrator. The podiatrist is a key member of the multidisciplinary diabetic foot team. At present there is a lack of trained podiatrists working in diabetic foot care. Mandatory minimal skills and equipment for those offering a podiatry service should be controlled to ensure that people with diabetes are not put at increased risk by unregulated, unqualified and poorly equipped practitioners.
IDF’s position is that management in the prevention and treatment of diabetic foot problems includes the following:
* Annual inspection of the foot
* Identification of the foot at risk
* Education of people with diabetes and healthcare professionals
* Appropriate foot wear
* Rapid treatment of all foot problems
Only through a multidisciplinary approach addressing the diversity of possible foot problems in people with diabetes can the desired reduction in amputation rates be achieved.
Conclusion
It is now time to take appropriate action to ensure that people with diabetes everywhere receive the quality of care that they deserve. It is hoped that global awareness of diabetes and its complications will be raised and that the necessary attention will be paid to the need for improved foot care for people with diabetes throughout the world.
IDF recommends that every individual with diabetes receive the best possible foot care. At the organizational level, diabetic foot care should be structured in such a way as to optimize treatment and prevention possibilities. For this to be feasible all parties involved (i.e. healthcare providers, policymakers and patient organizations) should recognize the need for combined action.

It is hoped that global awareness of diabetes and its complications will be raised and that the necessary attention will be paid to the need for improved foot care for people with diabetes throughout the world.
IDF recommends that every individual with diabetes receive the best possible foot care. At the organizational level, diabetic foot care should be structured in such a way as to optimize treatment and prevention possibilities. For this to be feasible all parties involved (i.e. healthcare providers, policymakers and patient organizations) should recognize the need for combined action.

Prevalence of risk factors predisposing to foot problems in patients on hemodialysis
The prevalence of peripheral arterial occlusive disease (PAOD) in the general public is estimated at 3.5% to 23% (O'Hare & Johansen, 2001). Among individuals with diabetes, the prevalence of PAOD is four to seven times greater than in those without diabetes (Armstrong, Lavery, & Harkless, 1998). The most common cause of chronic renal failure is diabetes, accounting for 44.3% of new end stage renal disease (ESRD) patients annually in the United States (U.S.) and 33% of new ESRD patients in Canada (U.S. Renal Data Systems [USRDS], 2003).
Annually more than 125,000 people in the U.S. undergo lower extremity amputations (Armstrong et al., 1998). Of these, between 50% and 80% are attributable to diabetes (Lavery et al., 1996; Spollett, 1998). There is some evidence to suggest that the prevalence of foot problems among patients with diabetes who also have ESRD is even greater than in patients with diabetes without ESRD (Eggers, Gohdes, & Pugh, 1999; Hill et al., 1996; Rith-Najariah & Gohdes, 2000). Thus, the potential burden of illness in a dialysis population is a costly one. According to some sources, however, between 50% and 85% of lower extremity amputations associated with diabetes could be avoided or delayed through appropriate educational and treatment programs (Edmonds, 1987; Halpin-Landry & Goldsmith, 1999).

Preventive Foot Care in Hemodialysis Patients
Comprehensive care of hemodialysis patients poses a significant challenge for nephrologists. Although protocol driven approaches by hemodialysis centers have significantly improved standardized care, significant gaps remain in overall medical care provided to hemodialysis patients. Admittedly, with improvement in care, mortality rate for dialysis patients has decreased by 10 percent from its peak in 1988; however, it still stands at a disturbing figure of 248 deaths per 1,000 patient-years. The life expectancy of ESRD patients is one-fourth to one-sixth of the age-matched general population, with cardiovascular disease being the most likely cause of death.
Diabetics on hemodialysis have even worse prognosis than other patients. Patients with diabetes and ESRD are admitted to the hospital on average 2.3 times per year, and only 27 percent of these patients will survive five years on hemodialysis. With improvement in overall care, mortality has improved in hemodialysis patient population, but perhaps not to the expected level for multiple reasons. One likely explanation is that although mortality may be less with improvement in one area of care, mortality in other neglected areas of care may negate these potential gains. It therefore remains imperative that the nephrology community does not lose sight of the fact that only comprehensive care of these patients will realize the goal of improvement in mortality and morbidity in this hemodialysis population.
Focus on Foot Care
One such area of care which remains under the radar is morbidity and mortality related to peripheral vascular disease and foot care. For the most part, at this stage, foot care attracts attention only after a problem has already arisen. There are no screening protocols in hemodialysis centers to identify the problem earlier on. As a result, preventive strategies to reduce morbidity and mortality related to this issue remain unaddressed. The magnitude of this problem is unrealized until you add to the equation that the majority of hemodialysis patients are diabetics as well. As a result, there remains a significant issue of lower extremity amputations in hemodialysis patients. Overall, 40 percent of patients in the United States starting chronic dialysis count diabetes mellitus as the primary cause of renal failure, making it the number one cause of CKD (Berman et al., 2001).
Patients with diabetes and chronic renal disease frequently present with a combination of the devastations of diabetes including: nephropathy, retinopathy and vasculopathy. The main focus of the care of these patients has been on the target organs like heart and kidneys. Therefore, early risk factors for diabetic foot complications may be disregarded, and this may lead to amputation—a failure for both the patient and physician. Diabetic foot complications, including amputation, add significantly to the morbidity and mortality of the patient with diabetes and CKD. However, of all the long-term complications of diabetes, foot complications may be the most preventable. In the United States, diabetes is the cause of 50 percent of nontraumatic lower extremity amputations and is increasing annually (Levin, 2002). The prevalence of lower extremity amputation for patients with diabetes and CKD is much greater than those without CKD. The rate of lower limb amputation for the population at large increased during a recent four-year period from 4.8 to 6.2/100 persons. During the same time frame, this rate of lower extremity amputation rose from 11.8 to 13.8/100 among persons with CKD attributed to diabetic nephropathy. The rate for patients with diabetes and CKD was 10 times greater than the diabetic population at large (Eggers, Gohdes, & Pugh et al., 1999). The cost of treating patients with diabetes is astronomical both financially and in terms of quality of life. The loss of a lower extremity or even part of a lower extremity greatly impacts quality of life. Depression after amputation is common. Leisure activities as well as employment status are altered. The mortality rate after amputation in patients with diabetes is 11 percent to 4 percent at one year, 20 percent to 50 percent at three years, and 39 percent to 68 percent at five years (Fritschi, 2001). The impact of disorganized foot care on overall morbidity and mortality in hemodialysis patients therefore can no longer be ignored. One could always argue the benefit of putting resources into such an endeavor.
Do diabetic foot examinations reduce the risk of amputation? For two decades, the United States Department of Health and Human Services (HHS) has used health promotion and disease prevention objectives to improve the health of the American people. The overall goal for diabetes in the Healthy People 2010 objective is, “Through prevention programs, reduce the disease and economic burden of diabetes and improve the quality of life for all persons who have or are at risk for diabetes” (HHS, 2000). A specific objective contained within this goal targets a 55 percent reduction in the rate of lower extremity amputations in persons with diabetes. This would amount to 1.8 lower extremity amputations per 1,000 patients with diabetes per year, down from 4.1 per 1,000 patients that occurred in 1997 (HHS, 2000). Several clinical studies in the nondialysis diabetic population have shown that coordinated programs to screen for high-risk feet and to provide regular foot care decreased lower extremity amputation rates. In a controlled study, 45 hemodialysis patients were assigned to intensive education and care management that included preventive foot care and 38 HD patients were assigned to usual care. Over the 12-month follow-up period, there were no amputations in the study group while there were five lower extremity amputations and two finger amputations in the control group. Mortality was unaffected over the short time of the study, but the morbidity benefit was obvious. Benefit from aggressive preventive care is therefore very likely if not proven through prospective randomized controlled trials.
Nobody would disagree that regular foot care is standard care for every diabetic, and diabetic patients on dialysis are no exception to this standard of care. The American Diabetic Association recommends, “All individuals with diabetes should receive a thorough foot examination at least once yearly to identify high-risk foot conditions.” The ADA goes on to recommend more frequent evaluation for people with one or more risk factors and a visual foot inspection at every visit with a healthcare professional for diabetic patients with neuropathy. “Examination of the foot is an obvious, fundamental step to identifying certain foot risk factors that can be modified, thus reducing the risk of ulceration and amputation” (Mayfield, Reiber et al. 1998). Foot lesions are the single most frequently mismanaged problem of patients with diabetes mellitus and chronic kidney disease (CKD). Recommendations for improving the survival of patients with diabetes and CKD include improvement in the foot care and education of both patients and nephrology healthcare providers regarding diabetic foot complications (Ritz, Koch et al. 1999).
Improving Foot Care
The real question is: Why is it so difficult to provide much needed foot care and how best to do it? One has to take into account the fact that it is not easy for a hemodialysis patient to keep multiple subspecialty appointments. Once-a-year visits for foot examination are not very likely to identify and trigger an early referral. Yet three times a week they are available to a hemodialysis nurse for simple inspection and basic exam of feet. It is logical to think that foot care protocols would be part of patient care. It is possible that it poses some legal and monetary issues for the hemodialysis companies in an era of shrinking reimbursements for hemodialysis patients. These concerns, for the most part, are not true. Legally, it is always safer to prevent than treat an issue after it has been allowed to manifest in medical care set up. Improving care of hemodialysis patients with foot care should theoretically keep patients out of hospitals and on a hemodialysis chair for monetary gains of the hemodialysis center.
Finally, of course one cannot put cost on saving a patients from morbidity and mortality associated with poor foot care. However, planning this care would require careful insight into all practical aspects of care and caregivers. To begin with, the screening process should be very basic level, which hemodialysis nurses are comfortable with. Time spent and protocol has to be very straightforward. It should simply identify and focus on confirming a “NORMAL” exam from “NOT NORMAL” requires physician evaluation. Hemodialysis nurses should then be able to pass that information in a quick computerized manner to nephrologists triggering referrals to podiatrist, interventional cardiologist/interventional radiologists committed to his/her group preferably again by the same computerized network. Unnecessary time spent on telephone calls have to be avoided using protocol driven care and computerized network. Information then would have to be exchanged seamlessly between hemodialysis centre nursing staff, nephrologists, interventionalist and podiatrist. The whole network would have to be HIPAA compliant and be easy to learn and adapt to the needs to dialysis facility and physician groups involved. Ideally the network should be able to blend in with existing networks involved in hemodialysis care as well as communicate with subspecialty groups.
In summary, preventive foot care for hemodialysis patients is lost in efforts and time spent to provide care in other much politicized areas of care. But ignoring prevention in this area leads to significant morbidity and mortality. There are no randomized controlled trials of intensive education and care management versus usual care of feet in diabetic dialysis patients. Nonetheless, diabetic dialysis patients are likely to benefit from examination of the foot as part of the routine dialysis care. Given the fact that prevention can be easily done in hemodialysis center by hemodialysis nursing staff, there is little reason not to introduce it. Three times a week contact between hemodialysis nurses and patient is a potential opportunity to assess risks, educate and provide early intervention for foot issues in CKD population. Simple measures such as routine foot screening and education for this high risk population can prevent ulcer-initiating events and detect small ulcers when they may heal with proper intervention. Preventive strategies should include protocol based strategy for referral to specialist. Computerized network should allow this to happen seamlessly and effortlessly to benefit all involved in hemodialysis care. In this regard, all involved in medical care of hemodialysis patients can no longer afford to ignore the importance of preventive care of hemodialysis patients.
