Necrotizing fasciitis (NF) results from an infection that attacks the fascia and subcutaneous tissues. The primary bacterial etiology is group A streptococcus, a facultative anaerobic bacterium. However, other bacteria may contribute. Sometimes called the “flesh-eating” disease because of the potentially devastating effect on the afflicted patient, NF can be monomicrobial or polymicrobial.

The four typical settings for NF are:

• surgical bowel or abdominal trauma surgery
• pressure ulcer and perianal abscess
• injection sites (especially in drug users)
• Bartholin abscess or minor vulvovaginal infection.

Because of the rapid course and ravaging nature of acute NF, clinicians must maintain a high index of suspicion if the patient has suggestive signs and symptoms. In 1990, puppeteer Jim Henson (best known for creating the Muppets) died from NF. At that time, little was known about the progression of group A streptococcal infection.
The disease can quickly cause death, so starting immediate treatment is even more crucial than confirming the diagnosis. Once the disease is suspected, antibiotics must be given immediately and the patient must be prepared for surgery at once. NF spreads rapidly, capable of progressing from a small lesion to death in days to weeks. Thus, delayed diagnosis increases the risk of death. Lack of knowledge about the disease and inability to recognize it promptly are the main reasons many victims die. This article can improve your knowledge base.

Overview

NF was discovered in 1871 by Joseph Jones, a Confederate Army surgeon. At that time, it was called hemolytic streptococcal gangrene, nonclostridial gas gangrene, nonclostridial crepitant cellulitis, necrotizing or gangrenous erysipelas, necrotizing cellulitis, bacterial synergistic gangrene, or synergistic necrotizing cellulitis.
NF involves the fascia, muscle compartments, or both. It can affect not only the muscle fascia but the superficial fascia. NF and cellulitis differ in the amount of tissue involved and extent of tissue involvement.
The most common areas of infection are the abdominal wall, perineum, and extremities. When NF affects the perineum and scrotum, it’s called Fournier gangrene, after the French dermatologist and virologist Alfred Jean Fournier.
The most common causes are trauma, surgery, and insect bites. The disease can affect persons of any age. Such comorbidities as diabetes, chronic renal failure, immunosuppressive therapy, hypertension, obesity, and malnutrition increase susceptibility.

Pathophysiology

NF falls into four classifications based on wound microbiology. Type 1, the most common, involves polymicrobial bacteria. Type 2 results from trauma and is associated with comorbidities. Type 3, rare in this country, stems from gram-negative marine bacteria. Type 4 is a fungal infection occurring mostly in immunocompromised persons. (See Comparing types of necrotizing fasciitis by clicking the PDF icon above.)

Disease progression

The four types of NF progress in a similar way. Bacteria secrete pyrogenic exotoxin A, which stimulates cytokines. These cyto­kines damage the endothelial lining; fluid then leaks into the extravascular space.
M proteins in streptococci and β-hemolytic streptococci exacerbate the immune reaction by inhibiting phagocytosis of polymorphonuclear leukocytes and normal neutrophil chemotaxis. As the immune reaction increases, blood vessels dilate, allowing toxins to leak through vessel walls, which in turn decreases blood flow. As the cascade continues, hypoxic conditions cause facultative aerobic organisms to grow and become anaerobic. These bacteria exacerbate destruction of surrounding cells and lead to release of carbon dioxide, water, hydrogen, nitrogen, hydrogen sulfide, and methane. As the infection continues to progress, toxins spread throughout the bloodstream and the patient becomes septic.

Assessment

Obtain the patient’s medical history and description of the wound. Determine when the changes first appeared and whether the affected area seemed to get worse recently.
In all NF types, patients commonly present with a small, painful area (possibly with entry marks) but no other signs or symptoms. The wound may appear as a bulla, cellulitis, or dermatitis, representing an infection developing in underlying tissues. The skin may have a wooden-hard feel as the infection progresses to the subcutaneous space and causes necrosis. The wound becomes discolored and necrotic; drainage is rare until surgical debridement begins. The patient quickly develops fever, chills, nausea, and vomiting. As NF progresses, bullae become dark purple with darkened edges; the patient grows disoriented and lethargic, and organ failure and respiratory failure
ensue. Without treatment, the patient dies.

Diagnosis

Diagnostic tests usually include magnetic resonance imaging, complete blood count with differential, comprehensive metabolic panel, and cultures. (See Diagnostic findings in necrotizing fasciitis by clicking the PDF icon above.)

Treatment

Immediate surgical debridement and broad-spectrum antibiotics are needed to stop the immune response to infection. Clindamycin, gentamicin, penicillin, or metronidazole may be given alone or in combination until culture results are available. Supportive care includes total parenteral nutrition for nutritional support, I.V. fluids, and oxygen. Limb amputation should be done only as a last resort.
Surgical debridement involves penetrating deep into the fascia and removing all necrotic tissue. After the first debridement, release of “dishwater fluid” may occur.
Administering hyperbaric oxygen therapy (HBOT) after the first debridement increases tissue oxygenation, thus reducing tissue destruction by anaerobic bacteria. During HBOT (usually given as a 90-minute treatment), the patient breathes 100% oxygen in an environment of increasing atmospheric pressure.
HBOT should be given in conjunction with surgical debridement (usually after each debridement) and should continue until necrotic tissue ceases and cell destruction stops. HBOT also promotes collagen synthesis and neoangiogenesis (new blood vessel growth), which boosts blood supply and oxygen to tissues.
Adverse effects of HBOT include ear pain, oxygen toxicity, and seizures. Ear pain can be minimized by swallowing or yawning. If the patient continues to have ear pain, ear tubes may be inserted by an otolaryngologist. During HBOT, air breaks (intervals of breathing room air) are important in controlling oxygen toxicity (the main cause of seizures).
Throughout the HBOT treatment period, wound dressings must be simple. Well-moistened gauze dressings and an abdominal pad provide good support. Once necrotic destruction occurs, dressings depend on wound size and the need to fill cavities. The patient may require a diverting colostomy, depending on wound
location and the amount of uncontrolled diarrhea. Blood glucose levels must be monitored before and after HBOT, as this treatment affects blood glucose.

Supportive care and follow-up treatment

During initial treatment, patients need supportive care and monitoring. Once they’re out of danger, begin teaching them how to prevent NF recurrences. Advise them to control blood glucose levels, keeping the glycated hemoglobin (HbA1c) level to 7% or less. Caution patients to keep needles capped until use and not to reuse needles. Instruct them to clean the skin thoroughly before blood glucose testing or insulin injection, and to use alcohol pads to clean the area afterward.
Before discharge, help arrange the patient’s aftercare, including home health care for wound management and teaching, social services to promote adjustment to lifestyle changes and financial concerns, and physical therapy to help rebuild strength and promote the return to optimal physical health. One helpful patient resource is the National Necrotizing Fasciitis Foundation. The Centers for Disease Control and Prevention section on necrotizing fasciitis includes “Common sense and great wound care are the best ways to prevent a bacterial skin infection.”
The life-threatening nature of NF, scarring caused by the disease, and in some cases the need for limb amputation can alter the patient’s attitude and viewpoint, so be sure to take a holistic approach when dealing with the patient and family. Today, NF has a much better survival rate than 2 decades ago when Jim Henson died. In my practice, I’ve seen four NF cases. Thanks to early identification, good wound care, and HBOT, these patients suffered only minimal damage.

Jim, a 52-year-old patient with colon cancer, received a new ostomy. He needed a custom fit for his appliance, which took 10 days. During this time, trying to obtain a good seal and treat the peristomal area wasn’t easy. Despite my best efforts, Jim’s skin was denuded from contact with stool. Although he was in great discomfort, he wanted to wait until my next visit to tell me about the problem. Fortunately, his wife was worried and contacted me directly.

Jim lives in a neighborhood with a low crime rate, so I’m able to see him within
a few hours of his wife’s call, even though it’s late at night. As it turns out, I make
extra visits to help him manage his stoma until the customized appliance is ready.  As with any home care situation, I’m ready to do my best for my patient.

Many home-care patients like Jim benefit from the interventions of a wound care clinician (WCC). More than one-third of all home-care admissions are wound related, and home wound care has become one of the fastest growing needs and skills in home-care services. So if you’re a WCC, you may want to consider home care as a practice option.

Delivering wound care in the home differs dramatically from delivering it in the hospital. Given the complexity of wound care and the multiple factors that affect healing, home wound care is a challenge. Some patients have chronic conditions, such as diabetes or wounds or open sores that don’t heal easily. In other cases, the patient or caregiver is unable to change dressings. That’s where the WCC comes in.

Special needs of home-care patients

Like other patients across the continuum of care, home-care wound patients require accurate and thorough wound assessment, as well as documentation that provides information about wound status and aids development of a plan that supports healing.
Of course, the plan of care must address the whole patient, not just the “hole” in the patient. The WCC must take into account comorbidities, individual wound-care requirements, assistance the patient may need due to physical or mental deficits, and nutritional support. Additional factors that affect wound-care strategies include wound characteristics, family support, and insurance guidelines and reimbursement.

Role of the WCC

The WCC’s role in home care includes providing clinical expertise, working with other healthcare team members, and providing education.

• The WCC provides clinical expertise regarding wound and ostomy care to ensure delivery of the highest quality of care. This expertise helps reduce the need for readmissions to the emergency department (ED) for wound-related complications. The WCC also plays a vital role in product awareness, formu-lary development, and maintenance of cost-effective, evidence-based practice in the agency.
• Working with other healthcare team members, the WCC serves as patient advocate, strengthening the relationship between patient and healthcare team members while promoting care coordination to help the patient achieve goals. Effective communication with the patient’s primary care pro­vider is essential to delivering the best-quality, research-based wound care. A tool for strengthening such communication is the SBAR (Situation-Background-Assessment-Recommendation) technique. SBAR structures conversations so all parties provide complete yet concise information. (See SBAR wound and skin provider communication record by clicking the PDF icon above).
• The WCC educates patients and family members about wound healing, dressing applications, and other interventions. Teaching families allows them to be involved in the patient’s care and start to take ownership of it. The WCC also educates home health aides, who can play a vital role in preventing such problems as pressure ulcers and may be responsible for ensuring staff members are aware of the products, procedures, and dressings available.

Challenges of home care

If you’re a WCC and considering home care as a career option, know that practicing in the home can be a real eye opener. For starters, consider geography. Shortly after I started as a wound care nurse/consultant in home care, I was visiting patients all over New Jersey, some days driving 200 miles. As I quickly discovered, once you enter the home, don’t assume you’ll simply change a dressing and then be on your way. Instead, you may find you are, in essence, the family case manager who’s expected to “fix everything.” This role requires equal doses of planning and creativity.

What’s more, expect to do some improvising. In acute-care settings, all the supplies you may need to prevent infection—gowns, gloves, masks—usually are within arm’s reach. But in home care, these supplies may be absent, meaning you’ll need to set up the cleanest environment you can under the circumstances. That might mean using disposable drapes and dressings. Be sure to carry large amounts of hand sanitizer.

Dressing selection is perhaps the biggest challenge in home wound care because
it involves not just wound-specific issues but financial and practical considerations. The ideal dressing in the home is one that needs to be changed only every other day, at most. Evidence shows it’s not practical to try to change dressings two or three times daily at home unless the family is providing care.

Develop a checklist

Because the home environment may lack all the resources you need, remembering every­thing you need to do before you leave the patient’s home may be challenging. To help keep things on track, develop a checklist of reminders that covers these points:

• Have necessary medical appointments been arranged? Does the patient have transportation to appointments?
• Are there sufficient supplies in the home?
• Is there enough medicine? If not, who will pick up the medicine?
• Are consults needed, such as social worker or physical therapist?
• Who will help with any activities of daily living that the patient is unable to do?
• Does the patient with diabetes have a glucometer?

Hours and safety concerns

Typical home wound-care hours are 8:30 a.m. to 4:30 p.m. But realistically, expect variations. For instance, as you’re about to leave, the patient might say, “My wife isn’t feeling well. Could you take her blood pressure?” This means you’ll stay a little longer.

When planning home visits, be aware of safety concerns. If visiting after hours could put you in danger, it’s safer to instruct the patient to call an ambulance and go to the local ED.

Reimbursement

Reimbursement is an important factor in wound care in the home. To be eligible for home care through Medicare, patients must be homebound—meaning they don’t routinely travel to run errands or visit or they’re not able to obtain or receive needed medical services. (With private insurance and workers’ compensation, eligibility requirements may be less restrictive.)

Know that a Medicare patient receives home care as an “episode.” Episodes are 60-day periods; within each 60-day episode, a $592 cap is allotted should a patient require supplies for wound or ostomy care needs. Except for negative-pressure wound therapy, a home care agency can’t bill Medicare for products used; instead, the home-care agency is responsible for the cost of all topical wound-care products and dressings. Agencies may keep patients on service even if they exceed the allowed amount, although patients reaching maximum benefits commonly are discharged from service. Home-care agencies have no choice but to discharge Medicare patients they find aren’t truly homebound.

Also, be aware that Medicare views home health service as an interim service. When a patient is no longer making progress, Medicare expects that the family will provide the patient’s care or the patient will enter a skilled care facility. So it’s important to work hard to obtain good outcomes—not just for the patient but to maintain Medicare reimbursement. Like many private insurance companies, Medicare reimbursement is based on pay for performance; if an agency doesn’t deliver optimal outcomes, it receives lower reimbursement, increasing its financial burden.

A worthwhile option

WCCs use their knowledge and clinical expertise to improve patient outcomes and teach patients, families, and other healthcare team members. They also give the agency recommendations for care and supplies that are evidence based and reflect current best practices in wound care. Accomplishing these goals in a timely fashion under various constraints can be challenging. But if you choose to work in the home, try to keep a smile on your face and joy in your voice for each patient and family. If you like challenges and want a job where you can apply your creativity and function independently, becoming a home-care WCC might be the right choice for you.

Often nurses get named in a lawsuit when they are involved in clearly negligent conduct that causes an injury to or the death of a patient. Examples include administering the wrong medication to the wrong patient or not positioning a patient correctly in the operative suite prior to surgery. Sometimes, however, the negligent behavior of a nurse is not as clear to the nurse involved in the care of the patient.
That was apparently the circumstance in the reported case, Olsten Health Services, Inc v. Cody.¹ In September 2000, Mr. Cody was the victim of a crime that resulted in paraplegia. He was admitted to a rehabilitation center and discharged on November 15, 2000. His physician ordered daily home health care services in order to monitor his “almost healed” Stage 2 pressure ulcer.² The home health care agency assigned a registered nurse (RN) to Mr. Cody and, after Mr. Cody’s healthcare insurance company would not approve daily visits, a reduced visit plan was approved by Mr. Cody’s physician.

A progressive problem

On November 16, 2000, the nurse visited Mr. Cody for the first time. During that visit, she did an admission assessment and noted that the pressure ulcer, located at the area
of the tailbone, measured 5 cm by 0.4 cm wide and 0.2 cm deep. She believed the pressure ulcer could be completely healed within 3 weeks. The nurse called Mr. Cody’s physician and left him a voice message concerning her visit and her findings.
On November 19, a second visit took place and the nurse observed and documented that Mr. Cody’s pressure ulcer was “100%” pink and no odor was detected.
On November 20, she attempted another visit but did not see Mr. Cody because the front gate surrounding his home was locked. The nurse buzzed the gate doorbell several times to no avail. She left a note on the front gate for the Cody family and left a voice message for Mr. Cody’s physician.

The next visit took place on November 21. The pressure ulcer was now only “90% pink” and had a “fetid” odor; this condition did not improve over the next 24 hours. The nurse documented this fact in her nurses’ notes. Again, she left a voice mail message for the physician concerning these findings.

The nurse could not get into the house on November 23, the next scheduled visit, so she again left a note on the house gate and left a voice mail message for the physician.
On November 24, the home health care nurse saw Mr. Cody and observed the pressure ulcer to be “90% pink” but the “fetid” odor was still present. In addition, Mr. Cody’s right lower extremity was swollen. She was concerned that the wound care that was to be done by the family or the health aide was not being done. Even so, she did not contact Mr. Cody’s physician or the patient again until November 27.

Mr. Cody’s pressure ulcer on November 27 had no odor but the home health aide who was also caring for Mr. Cody told the nurse that he was “very cold and having chills.” The nurse did not document this reported observation in her nurses’ notes.
Attempts to visit Mr. Cody on November 28 and 29 were again unsuccessful because of the locked gate at the front of the house. No one answered the buzzer, either. The nurse left another note on the house gate and left a voice mail message for the physician.

When the nurse saw Mr. Cody on November 30, she observed that the ulcer had “serious changes”: an increase in the serous drainage from the wound; the wound had a “fetid” odor; 80% of the wound was necrotic; the necrotic tissue was “undermined”; and the wound was significantly larger—9 cm by 8 cm wide and 1 cm deep.³ She left a voice mail message for Mr. Cody’s physician, but did not alter her visits to Mr. Cody’s home or attempt to see him over the next 2 days.

Admission to hospital

When the nurse did visit Mr. Cody on December 1, the pressure ulcer consisted of 40% necrotic tissue. She then told the family to take Mr. Cody to the physician’s office. Later that same day he was admitted to the hospital with a Stage 4 pressure ulcer that reached his tailbone. After 3 weeks of treatment, the ulcer measured 20 cm by 30 cm.

Mr. Cody endured many procedures during the following years to treat his
ulcer, but it never really healed. A “flap” enclosure was done to try to cover the wound.

Lawsuit

Mr. Cody sued the home health care company, alleging that the employees breached the standard of care by failing to appropriately diagnose and treat/or to prevent the formation or aggravation of pressure ulcers, resulting in severe and significant injury to him.

Verdict

The Florida Court of Appeals affirmed the trial court’s verdict in favor of Mr. Cody—a $3,050,000 verdict in economic damages⁴—on several legal bases, the most important for the purposes of this article being that the home health care agency and its employees were negligent in the care of Mr. Cody.

Key testimony

Key testimony in reaching this verdict came from the expert testimony of an RN and certified wound care expert. The nurse expert testified unequivocally that the home health care nurse breached the standard of nursing care. She said that not contacting the physician personally about Mr. Cody’s condition and the family being overwhelmed about his condition, but instead leaving voice mail messages on an answering machine, did not meet the standard of nursing care in this situation.
Additionally, the nurse expert testified that the nurse caring for Mr. Cody failed to recognize the symptoms of his deteriorating condition and did not intervene when necessary to avoid the infection he suffered from the deteriorating wound, and that her failure to do so resulted in the development of the Stage 4 ulcer that never healed.

Take-away points

So, what does this case tell you as a wound care professional caring for someone who has a pressure ulcer?

• Meet the standard of care. You must always meet the standard of care when caring for a patient. That means your care must be what other ordinary, reasonable, and prudent nurses caring for a patient with a decubitus ulcer would do in the same or similar circumstances in the same or similar community. Clearly, the nurse did not meet this standard in her care of Mr. Cody.
• Document accurately and completely. Remember that the nurse did not document Mr. Cody’s condition when the home health aide reported it to her. This omission may not only have compromised Mr. Cody’s care. If the communication during the trial became an “I told her”/”I don’t remember being told” debate when each party testified about the communication, it surely caused a rift between the aide and the nurse during the trial proceedings. Such a disagreement between defendant employees always helps a plaintiff’s case.
• Know that photographs can be used in court. This case used a specific form of evidence, demonstrative evidence: photographs taken of the pressure ulcer, which were admitted into evidence during the trial. The photographs were testified to by the wound care expert. In addition to her testimony, this evidence further showed the “natural and continual progression” of the ulcer as it existed on December 1, 2000.
• Understand the importance of expert testimony. In professional negligence cases, expert testimony is essential to establish the standard of care and to provide an opinion as to whether the standard of care was met or breached, the breach of which led to the injury to the patient. Typically, the attorney of a nurse cited in this type of case would want to use a certified wound care expert to support the care given. Apparently, the home care agency’s expert witness was not as convincing as the expert witness’s testimony for Mr. Cody.

Indeed, in this case, the expert witness’s testimony was invaluable and essentially secured a verdict for the plaintiff. Not only was the expert witness board certified but her testimony was credible, based on the evidence presented, and given after a careful review of Mr. Cody’s medical records, admission and discharge summaries from hospitals and health centers that provided care to Mr. Cody, the depositions of several doctors and nurses, and Mr. Cody’s deposition.

• Know your limits. The nurse’s conduct also stresses the importance of another legal principle—knowing the limits of your abilities and capabilities. Nowhere in the reported opinion are the RN’s qualifications listed or a reason given as to why she was selected to care for Mr. Cody. It is assumed she was not certified. Even basic nursing guidelines for wound care and communication to the physician were not followed. Why, then, did she agree to take this assignment? She did so not only at her own folly but to the detriment of Mr. Cody.
• Protect your patient. Last, and by no means least, this case stands for the principle that if you simply document something in the patient’s record that
  is important regarding the patient’s well-being and you just leave voice mail messages for a physician about that “something,” such conduct is not adequate. By simply leaving messages and notes, this RN violated an age-old principle in the law of professional negligence.⁵

Your duty in any situation in which the patient is at risk for a foreseeable and unreasonable risk of harm is to prevent that harm from happening insofar as humanly possible. What those specific steps might be will depend on the circumstances and your patient’s condition. Remember, liability is always fact-specific. Although legal principles exist, how each applies to a particular situation may vary.

Mr. Cody was clearly at risk for a foreseeable and unreasonable risk of harm—the further deterioration of his pressure ulcer. The nurse would only have had to intervene sooner by, for example (and as testified to by the expert witness), personally talking with his physician, visiting the patient more frequently when the deterioration began, contacting social services to help the family with its “overwhelmed” feelings, and following up with the home health aide’s observations of Mr. Cody.

Think about this, too: Nowhere in the court of appeals’ record was it indicated that Mr. Cody’s family or the physician ever received the notes or voice mail messages left by the nurse.⁶ At a minimum, wouldn’t you as the nurse want to follow up and check if those communications had been received?

St. Paul, MN: West; 2001). In this case, the home health care agency’s fault was attributed to be 70%. Mr. Cody’s degree of fault was assessed by the jury at 30%, most probably due to the inability of the home care nurse to be given access into the house on the days she visited and the family not providing the wound care required by Mr. Cody’s decubitus ulcer.

Study finds ultrasound therapy improves venous ulcer healing

In a study of 10 venous ulcers not responding to treatment, the use of noncontact ultrasound significantly reduced the wound area over 4 weeks of treatment.

It has been unclear exactly how ultrasound achieves its positive results. The
authors of “A prospective pilot study of ultrasound therapy effectiveness in refractory venous leg ulcers,” an article published online on February 1 by the International Wound Journal, found that patients treated with ultrasound and compression therapy had reduced inflammatory cytokines and bacterial counts, but the reduction wasn’t statistically significant.

The study found another important benefit for patients-reduced pain.

Serum albumin is not a goodindicator of nutritional status

Traditionally the standard of practice for wound care patients has been to review albumin blood levels as a measure of nutritional status and the effect of nutritional interventions. But as noted in The Role of Nutrition in Pressure Ulcer Prevention and Treatment: National Pressure Ulcer Advisory Panel White Paper, recent studies show that hepatic proteins (albumin, trans­thyretin, and transferrin) correlate with the severity of an underlying disease, not nutritional status. Moreover, many factors can alter albumin levels even when protein intake is adequate, including infection, acute stress, surgery, cortisone excess, and hydration status.

For these reasons, the National Pressure Ulcer Advisory Panel (NPUAP) and the Academy of Nutrition and Dietetics (previously known as The American Dietetic Association) recommend against using serum proteins as a nutritional assessment tool. Evaluation of lab values is just one part of the nutritional assessment process and should be considered along with other factors such as ensuring that the patient receives what is prescribed; daily food/fluid intake; changes in weight status, diagnosis, and medications; and clinical improvement in the wound.

For more information read “Serum proteins as markers of malnutrition: What are we treating?” and “Albumin as an indicator of nutritional status: Professional refresher.”

A profile of outpatients with wounds

“Wound care outcomes and associated cost among patients treated in US outpatient wound centers: Data from the US Wound Registry” a study using data from the US Wound Registry to determine outcomes and costs for outpatient wound care, found the mean patient age was 61.7 years, slightly more than half (52.3%) were male, most (71.3%) were white, and more than half (52.6%) were Medicare beneficiaries.

Other interesting findings:

• The mean number of serious comorbid conditions was 1.8.
• The most common comorbid conditions were obesity/overweight (71.3%), cardiovascular or peripheral vascular disease (51.3%), and diabetes (46.8%).
• Nearly two-thirds (65.8%) of wounds healed, with an average healing time
  of 15 weeks.
• In half of the wounds that healed, patients received only moist wound care and no advanced therapeutics.
• The mean cost for wound healing was $3,927.

The authors of the article, published in March’s Wounds, analyzed 5,240 patients with 7,099 wounds in 59 hospital-based outpatient wound centers in 18 states over 5 years.

LOI index comparable to ABI for assessing PAD in patients with type 2 diabetes

The pilot study “Lanarkshire Oximetry Index as a diagnostic tool for peripheral arterial disease in type 2 diabetes,” published in Angiology, compared the gold standard ankle bra­chial index (ABI) to the Lanarkshire Oximetry Index (LOI) in 161 patients with type 2 diabetes. Researchers assessed the patients for peripheral artery disease (PAD, defined as ABI < 0.9) using both ABI and LOI.

Using a LOI cut-off value of 0.9., the sensitivity and specificity for PAD were 93.3% and 89.1%, respectively. The study concluded that LOI is a “potentially useful alternative diagnostic test for PAD” in patients with type 2 diabetes.

LOI is a noninvasive procedure similar to ABI; both indices indicate whether it’s safe to apply compression to the limb of a patient who has lower leg ulceration or venous hypertension. With LOI, a pulse oximeter is used in place of a hand-held Doppler to determine the index.

Start planning for World Diabetes Day

It’s not too early to begin planning for World Diabetes Day, November 14. Started by the World Health Organization (WHO) and the International Diabetes Federation (IDF), the day is designed to raise global awareness of diabetes.

Access materials, including posters, a campaign book, and the Word Diabetes Day Logo, from IDF’s website, which also has activity ideas.

WHO estimates that more than 346 million people worldwide have diabetes, and the number is expected to double by 2030. World Diabetes Day is celebrated on November 14 to mark the birthday of Frederick Banting who, along with Charles Best, was instrumental in the discovery of insulin in 1922.

Guidelines for PAD in patients with diabetes and foot ulceration published

February’s issue of Diabetes/Metabolism Research and Reviews includes “Specific guidelines for the diagnosis and treatment of peripheral arterial disease in a patient with diabetes and ulceration of the foot 2011,” which is based on two companion International Working Group on the Diabetic foot papers. The guidelines state that if a patient’s PAD is impairing wound healing, revascularization through bypass or endovascular technique must be considered except in a few cases such as severely frail patients. Limb salvage rates after revascularization procedures are about 80-85%, and there is ulcer healing in > 60% at 12 months.

Other points of particular interest to wound care professionals:

• Patients with PAD and a foot infection are at high risk for major limb amputation, so should be treated as a “medical emergency”, preferably within 24 hours.
• Half of patients with diabetes, a foot ulcer, and PAD die within 5 years because of higher cardiovascular morbidity and mortality. Cardiovascular risk management should include “support for cessation of smoking, treatment of hypertension, and prescription of a statin as well as low-dose aspirin or clopidrogel.

AHA statement focuses on PAD in women

“A call to action: Women and peripheral artery disease: A scientific statement from the American Heart Association” summarizes evidence in this area and addresses risk-management issues. The statement notes that women (particularly black females) are more likely than men to experience graft failure of limb loss and calls for more research related to PAD and gender.
