The Affordable Care Act of 2010 requires nursing homes to have an acceptable Quality Assurance and Performance Improvement (QAPI) plan within a year after the start of the QAPI regulation. While the implementation of this regulation may be a year out, now is the time to start applying its principles. Reducing pressure ulcer rates is a great program to target for a QAPI plan.
A team approach
If you decide to use pressure ulcers as your QAPI project, don’t take on your entire program at once. Break the program down into system subsets (for example, admission process, prevention program, and weekly rounds). Determining the status of your program in each subset—completed, needs improvement, or not completed—can help you prioritize which areas to target. It’s important you have support from leadership for your efforts.
I’ll use the example of the admission phase (ensuring that within the first 24 hours, skin and risk concerns are identified and a temporary plan of care is implemented) to illustrate a QAPI project. To address this area, a team was created, including representation from staff members involved with the admission process. The team then used the problem-solving model Plan-Do-Study-Act (PDSA) to examine the process.
The first step in the PDSA cycle is to Plan. During this step, you:
• evaluate and analyze the current process to determine baseline data, which are used to measure progress
• identify system performance gaps
• determine the root cause of the performance gaps
• develop an action plan that identifies the goals, steps, responsible staff, and target dates.
In our example, the team determined that within the first 24 hours, skin inspections were being completed only 10% of the time. The root-cause analysis revealed that the admission nurses didn’t feel competent to document identified pressure ulcers or skin concerns, so they deferred it until the wound nurse was available. The team’s action plan included the following:
• Develop and educate all the facility nurses on how to complete and accurately document a skin inspection.
• Develop and implement a competency evaluation to assess the nurse’s ability to apply the knowledge at the bedside.
• Develop an ongoing plan to ensure all nurses receive this education during orientation and yearly thereafter.
The team also set the following goal:
By the end of the next quarter, 100% of admitted patients will have an accurate skin inspection completed within 24 hours of admission.
The second step of the PDSA cycle is Do. During this step, you implement and execute the plan, while documenting your observations and recording data.
In our example, the “Do” was to:
• develop and provide the skin inspection education and bedside competency evaluations
• develop an evaluation and tracking
system
• add the education to the orientation program
• add the education to the staff development calendar to be offered yearly.
The third step of the PDSA cycle is to Study: In this phase, you:
• reevaluate and analyze the system
• compare the results with the baseline data and predictions
• summarize what was learned and accomplished and what needs to be improved
• determine if another PDSA cycle is
necessary to continue to improve the system.
Once all staff had been properly educated and competency testing completed, an analysis of the rate and accuracy of the admission skin inspections done within 24 hours of admission was completed. It was found that 100% of the patients admitted had a complete skin inspection done within 24 hours. However, not all the nurses could accurately stage pressure ulcers, so it was determined that the system needed improvement to ensure accurate assessments.
The last step of the PDSA cycle is to Act. In this step, you:
• determine what changes need to be made
• modify the plan to continue to improve the system
• repeat the PDSA cycle as necessary.
In our example, the team determined the nurses needed more guidance and education on staging of pressure ulcers. Therefore, a new PDSA cycle was set to ensure the nurses are competent in this area.
Benefits for staff and patients
It may be difficult to start the QAPI project and at times the process may be stressful, but keep in mind that a successful pressure ulcer QAPI project can improve not only the quality of life and care of your patients but also morale and team building for your staff. n

Study finds less-invasive method for identifying osteomyelitis is effective
Researchers have found that using hybrid 67Ga single-photon emission computed tomography and X-ray computed tomography (SPECT/CT) imaging combined with a bedside percutaneous bone puncture in patients with a positive scan is “accurate and safe” for diagnosing osteomyelitis in patients with diabetes who have a foot ulcer without signs of soft-tissue infection.
The new method, which avoids an invasive bone biopsy, has a sensitivity of 88% and a specificity of 93.6%. In the study of 55 patients, antibiotic treatment was avoided in 55% of suspected cases.
MRSA strains will likely continue to coexist in hospitals and communities
The strains of methicillin-resistant Staphylococcus aureus (MRSA) differ in the hospital and community settings, and both are likely to coexist in the future, according to a study in PLOS Pathogens.
C. difficile prevention actions fail to stop spread
Despite increasing activities to prevent the spread of Clostridium difficile, infection from C. difficile remains a problem in healthcare facilities, according to a survey of infection preventionists by the Association for Professionals in Infection Control and Epidemiology (APIC).
The survey found that 70% of preventionists have adopted additional interventions in their healthcare facilities since March 2010, but only 42% have seen a decline in C. difficile infection rates; 43% saw no decline.
A total of 1,087 APIC members completed the survey in January 2013. The survey also found that more than 92% of respondents have increased emphasis on environmental cleaning and equipment decontamination practices, but 64% said they rely on observation, rather than more accurate and reliable monitoring technologies, to assess cleaning effectiveness.
In addition, 60% of respondents have antimicrobial stewardship programs at their facilities, compared with 52% in 2010. Such programs promote the appropriate use of antibiotics, which can help reduce the risk of C. difficile infection.
Mast cells may not play significant role in wound healing
“Evidence that mast cells are not required for healing of splinted cutaneous excisional wounds in mice,” published in PLOS One, analyzed wound healing in three types of genetically mast-deficient mice and found they reepithelialized their wounds at rates similar to control mice. At the time of closure, the researchers found that scars in all the mice groups were similar in both “quality of collagen deposition and maturity of collagen fibers.” The findings fail to support the previously held belief that mast cells are important in wound healing.
Study identifies effective casting for diabetes-related plantar foot ulcers
Nonremovable casts that relieve pressure are more effective than removable casts or dressings alone for the treatment of plantar foot ulcers caused by diabetes, according to an analysis of clinical trials.
The authors of “Pressure-relieving interventions for treating diabetic foot ulcers,” published by The Cochrane Library, reviewed 14 randomized clinical trials that included 709 participants. Nonremovable pressure-relieving casts were compared to dressings alone, temporary therapeutic shoes, removable pressure-relieving devices, and surgical lengthening of the Achilles tendon.
The study also notes that when combined with Achilles tendon lengthening, nonremovable devices were more successful in one forefoot ulcer study than the use of a nonremovable cast alone.
Most studies were from the United States (five) and Italy (five), with Germany, the Netherlands, Australia, and India each contributing one study.
Prescriber preference drives use of antibiotics in long-term care
The study of 66,901 patients from 630 long-term care facilities found that 77.8%
received a course of antibiotics. The most common length (41%) was 7 days, but the length exceeded 7 days in 44.9% of patients. Patient characteristics were similar among short-, average-, and long-duration prescribers.
The study authors conclude: “Future trials should evaluate antibiotic stewardship interventions targeting prescriber preferences to systematically shorten average treatment durations to reduce the complications, costs, and resistance associated with antibiotic overuse.”
Electrophysical therapy may be helpful for diabetic foot ulcers
The authors of the study in International Wound Journal reviewed eight trials with a combined total of 325 patients. Five studies were on electrical stimulation, two on phototherapy, and one on ultrasound. Because of the small number of trials, the possibility of harmful effects can’t be ruled out, and the authors recommend “high-quality trials with larger sample sizes.”
Significant geographic variations in spending, mortality exist for diabetic patients with foot ulcers and amputations
The study in Journal of Diabetes and Its Complications found that higher spending wasn’t associated with a significant reduction in 1-year patient mortality. In addition, rates of hospital admission were associated with higher per capita spending and higher mortality rates for patients.
Home-based exercise program improves life for lymphedema patients
An individualized, home-based progressive resistance exercise program improves upper-limb volume and circumference and quality of life in postmastectomy patients with lymphedema, according to a study published in the Journal of Rehabilitation Research and Development.
With so much focus on dressing choices, it’s easy to forget the importance of wound cleansing. Cleaning a wound removes loose debris and planktonic (free-floating) bacteria, provides protection to promote an optimal environment for healing, and facilitates wound assessment by optimizing visualization of the wound. You should clean a wound every time you change a dressing, unless it’s contraindicated.
Here’s a review of how to choose and use a wound cleanser so you can see if your practice is up to date. (more…)

Description
A hydrocolloid dressing is a wafer type of dressing that contains gel-forming agents in an adhesive compound laminated onto a flexible, water-resistant outer layer. Some formulations contain an alginate to increase absorption capabilities. The wafers are self-adhering and available with or without an adhesive border and in various thicknesses and precut shapes for such body areas as the sacrum, elbows, and heels.

Assessing moisture and pressure risk in elderly patients continues to be a focus for clinicians in all settings, particularly long-term care. Ongoing research challenges our ideas about and practices for cleansing and protecting damaged skin. Until recently, most wound care clinicians have cleansed long-term care patients’ skin with mild soap and water. But several studies have shown pH-balanced cleansers are more efficient than soap and water for cleansing the skin of incontinent patients.
Various terms are used to describe skin breakdown related to moisture—incontinence-associated dermatitis, perineal dermatitis, diaper rash, intertriginal dermatitis, intertrigo, moisture-related skin damage, moisture-associated skin damage, and even periwound dermatitis. This article uses moisture-associated skin damage (MASD) because it encompasses many causes of skin breakdown related to moisture. Regardless of what we call the condition, we must do everything possible to prevent this painful and costly problem.
Skin assessment
Start with an overall assessment of the patient’s skin. Consider the texture and note dryness, flaking, redness, lesions, macerated areas, excoriation, denudement, and other color changes. (See Identifying pressure and moisture characteristics by clicking the PDF icon above.)
Assessing MASD risk
A patient’s risk of MASD can be assessed in several ways. Two of the most widely used pressure-ulcer risk scales, the Norton and Braden scales, address moisture risk. The Norton and Braden subscales should drive your plan for preventing skin breakdown related to moisture or pressure. The cause of breakdown (moisture, pressure, or shear/friction) must be identified, because treatment varies with the cause.
Both the Norton and Braden scales capture activity, mobility, and moisture scores. The Braden scale addresses sensory perception, whereas the Norton scale identifies mental condition. (See Subscales identifying pressure, shear, and moisture risk by clicking the PDF icon above.) Also, be aware that two scales have been published for perineal risk, but neither has been used widely.
You must differentiate pressure- and moisture-related conditions to determine correct treatment. Patients who are repositioned by caregivers are at risk for friction or shear. Also, know that agencies report pressure-ulcer prevalence. Care providers no longer classify mucous-membrane pressure areas in skin prevalence surveys; mucous membranes aren’t skin and don’t have the same tissue layers. Furthermore, don’t report skin denudement from moisture (unless pressure is present) in prevalence surveys.
When moisture causes skin breakdown
Skin has two major layers—epidermis and dermis. The epidermis itself has five layers: The outermost is the stratum corneum; it contains flattened, keratin protein–containing cells, which aid water absorption. These cells contain water-soluble compounds called natural moisturizing factor (NMF), which are surrounded by a lipid layer to keep NMF within the cell. When skin is exposed to moisture, its temperature decreases, the barrier function weakens, and skin is more susceptible to pressure and friction/shear injury. Also, when urea in urine breaks down into ammonia, an alkaline pH results, which may reactivate proteolytic and lipolytic enzymes in the stool. (See Picturing moisture and pressure effects by clicking the PDF icon above.)
Caring for moisture-related skin breakdown
The standard of care for moisture-related skin breakdown includes four major components: cleanse, moisturize, protect, and contain. Specific products used for each component vary with the facility’s product formulary.
Cleanse
Gently wash the area using a no-rinse cleanser with a pH below 7.0. Don’t rub the skin. Pat dry.
Moisturize
Use creams containing emollients or humectants. Humectants attract water to skin cells and help hold water in the cells; don’t use these products if the skin is overhydrated. Emollients slow water loss from skin and replace intracellular lipids.
Protect
Options for skin protectants include:
• liquid film-forming acrylate sprays or wipes
• ointments with a petroleum, zinc oxide, or dimethicone base
• skin pastes. Don’t remove these products totally at each cleansing, but do remove stool, urine, or drainage from the surface and apply additional paste afterward. Every other day, remove the paste down to the bare skin using a no-rinse cleanser or mineral oil.
Be sure to separate skinfolds and use products that wick moisture rather than trap it. These may include:
• commercial moisture-wicking products
• a light dusting with powder containing refined cornstarch or zinc oxide—not cornstarch from the kitchen or powder with talc as the only active ingredient
• abdominal pads.
Contain
To keep moisture away from skin, use absorbent underpads with wicking properties, condom catheters (for males), fecal incontinence collectors, fecal tubes (which require a healthcare provider order), or adult briefs with wicking or gel properties. Call a certified ostomy or wound care nurse for tips on applying and increasing wear time for fecal incontinence collectors.
If 4″ × 4″ gauze pads or ABD pads are saturated more frequently than every 2 hours, consider applying an ostomy or specially designed wound pouch to the area. Collecting drainage allows measurement and protects skin from the constant wetness of a saturated pad.
Don’t neglect the basics, for example, know that wet skin is more susceptible to breakdown. Turn the patient and change his or her position on schedule. Change linens and underpads when damp, and consider using a low-air-loss mattress or bed or mattress with microclimate technology.
Also, be aware that fungal rashes should be treated with appropriate medications. If the patient’s skin isn’t too moist, consider creams that absorb into the skin; a skin-protecting agent can be used as a barrier over the cream. Besides reviewing and using the standards of care, you may refer to the Incontinence-Associated Dermatitis Intervention Tool, which has categories related to skin damage. See the “Incontinence-Associated Dermatitis Intervention Tool” (IADIT).
Bottom line on skin breakdown
To help prevent skin breakdown related to moisture, assess patients’ skin appropriately, determine treatment using evidence-based guidelines, and implement an appropriate plan of care.

Most patients are distressed to learn they need ostomy surgery to divert stool, urine, or both. Adapting to ostomy surgery can be difficult at best, even with today’s advanced technology and the wide assortment of ostomy supplies available. While recovering from the surgery itself, patients must learn how to contain or control feces or urine and how to minimize odor—without feeling like a social outcast.
This article reviews three types of ostomy surgery—colostomy, ileostomy, and urostomy. Subsequent articles will discuss ostomy management and treatment of stomal and peristomal skin complications. (more…)

“Shawnee Medical Center wound care quick reference guide.” This is a handy one-page reference guide that includes photographs and recommendations.
“How-to guide: Prevent pressure ulcers—pediatric supplement.” This guide, tailored for pediatrics, describes key evidence-based care components for preventing pressure ulcers and describes how to implement these interventions.
You can also access case studies from a variety of facilities around the United States.
The National Lymphedema Network is a nonprofit organization founded in 1988 to provide education and other information to healthcare professionals and patients with lymphedema, as well as the general public. The site includes an explanation of lymphedema that may be helpful for you to use in teaching your patients. It also includes access to some of the articles from the newsletter LymphLink.
Many patients with chronic wounds have diabetes. To ensure those patients receive the best possible care, you can refer to the 2013 Standards of Medical Care in Diabetes from the American Diabetes Association, which were published in the January issue of Diabetes Care.
The journal provides a summary of the revisions and an executive summary of the standards related to each area, including diagnosis, testing, prevention, monitoring, and pharmacologic and nonpharmacologic management.
The guidelines include valuable information related to neuropathy screening and treatment and foot care. Recommendations for foot care include performing an annual comprehensive foot examination to identify risk factors predictive of ulcers and amputations. The foot examination should include inspection, assessment of foot pulses, and testing for loss of protective sensation.
An Unna boot is a special dressing of inelastic gauze impregnated with zinc, glycerin, or calamine that becomes rigid when it dries. It is used for managing venous leg ulcers and lymphedema in patients who are ambulatory. When the patient walks, the rigid dressing restricts outward movement of the calf muscle, which directs the contraction force inward and improves the calf-muscle pumping action, thereby improving venous flow. An Unna boot does not provide compression and is contraindicated for arterial insufficiency. (more…)
Chronic venous insufficiency (CVI) is the most common cause of lower extremity wounds. The venous tree is defective, incapable of moving all the blood from the lower extremity back to the heart. This causes pooling of blood and intravascular fluid at the lowest gravitational point of the body—the ankle.
This article has two parts. Part 1 enhances your understanding of the disease and its clinical presentation. Part 2, which will appear in a later issue, explores the differential diagnosis of similar common diseases, the role that coexisting peripheral artery disease (PAD) may play, disease classification of venous insufficiency, and a general approach to therapy.
The most common form of lower extremity vascular disease, CVI affects 6 to 7 million people in the United States. Incidence increases with age and other risk factors. One study of 600 patients with CVI ulcers revealed that 50% had these ulcers for 7 to 9 months, 8% to 34% had them for more than 5 years, and 75% had recurrent ulcers.
Thrombotic complications of CVI include thrombophlebitis, which may range from superficial to extensive. If the thrombophlebitis extends up toward the common femoral vein leaving the leg, proximal ligation may be needed to prevent clot extension or embolization.
Understanding normal anatomy and physiology
Lower extremity veins flow horizontally from the superficial veins to the perforating veins and then into the deep veins. Normally, overall venous blood flows vertically against gravity from the foot and ankle upward toward the inferior vena cava (IVC). This antigravity flow toward the IVC results from muscular contraction around nonobstructed veins and one-way valves that close as blood passes them. These valves prevent abnormal backward blood flow toward the foot and ankle region.
The lower extremities have four types of veins. Superficial veins are located within the subcutaneous tissue between the dermis and muscular fascia. Examples are the greater and lesser (smaller) saphenous veins. Perforating veins connect the superficial veins to the deep veins of the leg. The deep veins are located below the muscular fascia. The communicating veins connect veins within the same system.
The greater saphenous vein is on the leg’s medial (inner) side. It originates from the dorsal veins on top of the foot and eventually drains into the common femoral vein in the groin region. By way of perforating veins, the greater saphenous vein drains into the deep venous system of both the calf and thigh.
The lesser saphenous vein is situated on the lateral (outer) side of the leg and originates from the lateral foot veins. As it ascends, it drains into the deep system at the popliteal vein behind the knee. Communicating veins connect the greater saphenous vein medially and the lesser saphenous vein laterally.
Intramuscular veins are the deep veins within the muscle itself, while the intermuscular veins are located between the muscle groups. The intermuscular veins are more important than other veins in development of chronic venous disease. Below the knee, the intermuscular veins are paired and take on the name of the artery they accompany—for example, paired anterior tibial, paired posterior tibial, and paired peroneal veins. Eventually, these veins form the popliteal vein behind the knee, which ultimately drains into the femoral vein of the groin.
As the common femoral vein travels below the inguinal ligament of the groin, it’s called the external iliac vein. Eventually, it becomes the common iliac vein, which drains directly into the IVC.
Pathophysiology
Abnormally elevated venous pressure stems from the leg’s inability to adequately drain blood from the leg toward the heart. Blood drainage from the leg requires the muscular pumping action of the leg onto the veins, which pump blood from the leg toward the heart as well as from the superficial veins toward the deep veins. Functioning one-way valves within the veins close when blood passes them, preventing blood from flowing backward toward the ankle. This process resembles what happens when you climb a ladder with intact rungs: As you step up from one rung to the next, you’re able to ascend.
CVI and the “broken rung” analogy
If the one-way valves are damaged or incompetent, the “broken rung” situation occurs. Think how hard it would be to climb a ladder with broken rungs: You might be able to ascend the ladder, but probably you would fall downward off the ladder due to the defective, broken rungs.
Normally, one-way valves ensure that blood flows from the lower leg toward the IVC and that the superficial venous system flows toward the deep venous system. The venous system must be patent (open) so blood flowing from the leg can flow upward toward the IVC. Blockage of a vein may result from an acute thrombosis (clot) in the superficial or deep systems. With time, blood may be rerouted around an obstructed vein. If the acute thrombosis involves one or more of the one-way valves, as the obstructing thrombosis opens up within the vein’s lumen, permanent valvular damage may occur, leading to post-thrombotic syndrome—a form of CVI.
CVI may result from an abnormality of any or all of the processes needed to drain blood from the leg—poor pumping action of the leg muscles, damage to the one-way valves, and blockage in the venous system. CVI commonly causes venous hypertension due to reversal of blood flow in the leg. Such abnormal flow may cause one or more of the following local effects:
leg swelling
tissue anoxia, inflammation, or necrosis
subcutaneous fibrosis
Compromised flow of venous blood or lymphatic fluid from the extremity.
“Water balloon” analogy
The effect of elevated venous pressure or hypertension is worst at the lowest gravitational point (around the ankle). Pooling of blood and intravascular fluid around the ankle causes a “water balloon” effect. A balloon inflated with water has a thin, easily traumatized wall. When it bursts, a large volume of fluid drains out. Due to its thicker wall, a collapsed balloon that contains less fluid is more difficult to break than one distended with water.
In a leg with CVI, subcutaneous fluid that builds up requires a weaker force to break the skin and ulcerate than does a nondistended leg with less fluid. This principle is the basis for compression therapy in treating and preventing CVI ulcers.
Effects of elevated venous pressure or hypertension
Increased pressure in the venous system causes:
abnormally high pressure in the superficial veins—60 to 90 mm Hg, compared to the normal pressure of 20 to 30 mm Hg
dilation and distortion of leg veins, because blood refluxes abnormally away from the heart and toward the lower leg and may move from the deep venous system into the superficial veins.
Abnormal vein swelling from elevated pressure in itself may impair an already abnormally functioning one-way valve. For instance, the valve may become more displaced due to the increase in intraluminal fluid, which may in turn worsen hypertension and cause an increase in leg swelling. Increased pressure from swollen veins also may dilate the capillary beds that drain into the veins; this may cause leakage of fluid and red blood cells from capillaries into the interstitial space, exacerbating leg swelling. Also, increased venous pressure may cause fibrinogen to leak from the intravascular plasma into the interstitial space. This leakage may create a fibrin cuff around the capillary bed, which may decrease the amount of oxygen entering the epidermis, increase tissue hypoxia, trigger leukocyte activation, increase capillary permeability, and cause local inflammation. These changes may lead to ulceration, lipodermatosclerosis, or both.
Visible changes may include dilated superficial veins, hemosiderin staining due to blood leakage from the venous tree, atrophie blanche, and lipodermatosclerosis. (See CVI glossary by clicking the PDF icon above.) Both atrophie blanche and lipodermatosclerosis result from local tissue scarring secondary to an inflammatory reaction of the leg distended with fluid.
Lipodermatosclerosis refers to scarring of subcutaneous tissue in severe venous insufficiency. Induration is associated with inflammation, which can cause the skin to bind to the subcutaneous tissue, causing narrowing of leg circumference. Lymphatic flow from the leg also may become compromised and inhibited in severe venous hypertension, causing additional leg swelling.
Patient history
In a patient with known or suspected CVI, a thorough history may lead to a working diagnosis. Be sure to ask the patient these questions:
Do you have pain?
Is your pain worse toward the end of the day?
Is the pain relieved with leg elevation at night?
Is it relieved with leg elevation during the day?
Do you have leg pain that awakens you at night?
How would you describe the pain?
Does the skin on your leg feel tight or irritated?
Have you noticed visible changes of your leg?
Do you have a leg ulcer?
Also determine if the patient has comorbidities that may exacerbate CVI, including PAD, renal failure, venous thrombosis, lymphedema, diabetes mellitus, heart failure, or malnutrition. (See CVI risk factors by clicking the PDF icon above .)
Common CVI symptoms
Approximately 20% of CVI patients have symptoms of the disease without physical findings. These symptoms may include:
tired, “heavy” legs that feel worse toward the end of the day
discomfort that worsens on standing
legs that feel best in the morning after sleeping or after the legs have been
elevated during the day.
Although patients may report leg discomfort, the history indicates that it doesn’t awaken them at night. Be aware that discomfort from CVI differs from that caused by PAD. With PAD, patients may report pain on exercise (claudication), pain with elevation (nocturnal pain), or constant pain (resting pain).
Signs of CVI (with or without ulcers) include:
leg swelling (seen in 25% to 75% of patients)
skin changes (such as hemosiderin staining or dermatitis)
telangiectasia, reticular veins, or both; while these are the most common signs, they represent an overall less severe finding
varicose veins with or without bleeding, occurring in one-third of patients with CVI.
Venous ulcers
Venous ulcers are the most common type of lower extremity ulcer. They’re commonly found on the medial aspect of the lower extremity, from the ankle to the more proximal calf area. Usually, they arise along the course of the greater saphenous vein, but also may be lateral and may occur at multiple locations. They aren’t found above the knee or on the forefoot. Venous ulcers are shallower than arterial ulcers and have considerable exudate consistent with drainage from a ruptured water balloon. They may extend completely around the leg.
CVI: From a heavy sensation to visible changes
In patients with CVI, blood flows within a lower extremity in an abnormal, reverse direction, causing build-up of blood and intravascular fluid around the ankle. Initially, this may cause only a sensation of heavy legs toward the end of the day, with no visible changes. Eventually, it may lead to venous ulcers or other visible changes. This abnormal blood flow results from dysfunction of the normal mechanisms that drain blood from the leg against gravity into the IVC.

The number of people with diabetes who are meeting the ABC goals—hemoglobin A1C, blood pressure, and LDL cholesterol—has risen significantly in recent years, according to a study published by Diabetes Care. Patients meeting all three goals rose from about 2% in 1988 to about 19% in 2010.
Gains were made in each of the ABC goals, based on 2007 to 2010 data: 53% of patients met A1C goals, compared to 43% in 1988 to 1994 data; 51% met blood pressure goals, compared to 33%; and 56% met LDL goals, compared to 10%.
Younger people were less likely to meet A1C and cholesterol goals. Compared with non-
Hispanic whites, Mexican Americans were less likely to meet A1C and LDL goals and non-Hispanic blacks were less likely to meet blood pressure and LDL goals.
The researchers analyzed data from the National Health and Nutrition Examination Surveys from 1988–1994, 1999–2002, 2003–2006, and 2007–2010. Nearly 5,000 people age 20 or older participated.
Although progress had been made, the researchers conclude, “Despite significant improvement during the past decade, achieving the ABC goals remains suboptimal among adults with diabetes, particularly in some minority groups.”
Daily bathing with chlorhexidine-impregnated washcloths reduces infection risk
A study in The New England Journal of Medicine reports that daily bathing with chlorhexidine-impregnated washcloths reduces the risk of becoming infected with multidrug-resistant organisms and subsequent development of hospital-acquired bloodstream infections in intensive care unit patients.
“Effect of daily chlorhexidine bathing on hospital-acquired infection” included 7,727 patients in nine intensive care and bone marrow units in six hospitals. The units were randomly assigned to bathe patients with either no-rinse 2% chlorhexidine-impregnated washcloths or nonantimicrobial washcloths for 6 months; then, the units switched to the opposite product for 6 months.
The rate of infection with multidrug-resistant organisms was 23% lower in the chlorhexidine group and the rate of hospital-acquired bloodstream infection was 28% lower in the chlorhexidine group.
Patients tend not to wear custom-made footwear for preventing diabetic foot ulcers
Adherence to wearing prescription custom-made footwear was low among patients with diabetes, neuropathy, and a recently healed plantar foot ulcer, according to a study in Diabetes Care. The low adherence was particularly notable at home, where patients did the most walking.
Factors associated with higher adherence included lower body mass index, more severe foot deformity, and more appealing footwear.

A JAMA study says that a 200-mg once-daily dose of oral tedizolid phosphate over 6 days was as effective as 600 mg of oral linezolid every 12 hours for 10 days in patients with acute bacterial skin and skin-structure infections, including cellulitis or erysipelas, major cutaneous abscesses, and wound infections.
A shorter course of tedizolid may be a “reasonable alternative” to linezolid for treating acute bacterial skin and skin-structure infections, the study concludes.
Water-based exercise improves ROM in patients with long-term arm lymphedema
A study of breast cancer survivors (median 10 years after surgery) with lymphedema found that a water-based exercise program improved shoulder range of motion (ROM).
The program consisted of at least twice-weekly water-based exercise for 8 weeks. At first, participants were supervised, but later they exercised independently. Although lymphedema status didn’t change, those who performed water-based exercise had an increase in ROM, showing improvement years after surgery.
Dehydrated amniotic membrane allograft possible option for treating chronic wounds
A dehydrated amniotic membrane allograft (EpiFix) was used to treat four patients whose wounds hadn’t closed after conservative and advanced measures and who had been referred for plastic procedures. A variety of wounds healed (located on the elbow, knee, hand, and ankle) after one to three applications of the amniotic material, which patients tolerated well. The wounds remained closed several months later.
Study casts doubt on MLD’s role in breast cancer–related lymphedema
A meta-analysis published in the World Journal of Surgical Oncology found the “current evidence” from randomized clinical trials “does not support” the use of manual lymphatic drainage (MLD) in preventing or treating lymphedema in patients with breast cancer.
The authors analyzed 10 randomized clinical trials with 566 patients.
CDC issues additional prevention steps for carbapenem-resistant Enterobacteriaceae
On Feb. 14, the Centers for Disease Control and Prevention (CDC) issued additional prevention steps for carbapenem-resistant Enterobacteriaceae (CRE). Increased reports of CRE prompted the action: Of the 37 unusual forms of CRE reported in the U.S., the last 15 have been reported since July 2012.
• When a CRE is identified in a patient with a history of an overnight stay in a healthcare facility (within the last 6 months) outside the U.S., send the isolate to a reference laboratory for confirmatory susceptibility testing and test to determine the carbapenem resistance mechanism.
• For patients admitted to healthcare facilities in the U.S. after recently being hospitalized (within the last 6 months) in countries outside the U.S., consider performing rectal screening cultures to detect CRE colonization, and place patients on contact precautions while awaiting the results.
Examples of Enterobacteriaceae include Klebsiella species and Escherichia coli. CRE are Enterobacteriaceae with high levels of resistance to antibiotics, including carbapenems. CRE infections most commonly occur among patients who are receiving antibiotics and significant medical treatment for other conditions.
At one time or another, all wound care professionals encounter a chronic wound, defined as a wound that fails to heal in an orderly and timely manner. Globally, about 67 million people (1% to 5% of the world’s population) suffer chronic wounds. In the United States, chronic wounds affect 6.5 million people and cost more than $25 billion annually to treat. (more…)
In most cases, amputation (removal of an extremity, digit, or other body part) is a surgical intervention performed to remove tissue affected by a disease and, in some cases, to provide pain relief. Fecal and urinary diversion surgeries also are considered amputations. Amputations and fecal or urinary diversions (ostomies) require extensive rehabilitation and adaptation to a new way of life, with physiologic and psychological impacts. Although diversions and ostomies usually are less visible to others than other types of amputations, they call for similar patient education, rehabilitatio n, and lifelong counseling.
The primary goal of therapy for ostomates and amputees is to resume their presurgical lifestyle to the greatest extent possible and to adapt to their new circumstances. Preoperative assessment and training interventions have proven valuable. Having a clear understanding of the surgical intervention helps reduce postoperative anxiety and depression, which can pose roadblocks to patients’ adaptation or response to their new situation. Successful interventions should be done by healthcare professionals who are trained in caring for ostomates and amputees.
Ostomates and amputees experience similar psychosocial challenges, body-
image problems, and sexuality concerns. This article focuses on these three issues. For a summary of other issues these patients may experience, see Other problems amputees and ostomates may face by clicking the PDF icon above.
Psychosocial challenges
Ostomates and amputees may experience depression, anxiety, fear, and many other concerns related to the surgical procedure—concerns that center on whether they’ll be able to resume their presurgical lifestyle. Many worry about social isolation and loss of income. Some fear both the primary disease process and the lifestyle changes induced by surgery. Anxiety may impede their social interactions and lead to significant psychological problems. Appropriate and effective counseling and therapy must be planned and provided. (But be aware that untrained or inexperienced healthcare professionals may not be able to provide the guidance the patient needs to feel comfortable; some may be unable even to offer information about available support systems.)
These patients also may find themselves socially isolated, in part due to loss of employment or the socioeconomic consequences of a decreased income. Some experience fear and worry when anticipating lifestyle changes caused by loss in or change of function, adaptation to the prosthesis, and treatment costs.
Maintaining social contact after surgery is extremely important to recovery and adaptation to the amputation or ostomy. The United Ostomy Associations of America and the Amputee Coalition encourage patients to maintain social involvement. Both groups suggest patients discuss their feelings, thoughts, and fears with a trusted family member, friend, or partner. Both organizations sponsor and encourage support-group involvement. In some cases, emotional support from other amputees or ostomates with a similar experience may be appropriate; some patients may be more comfortable sharing thoughts and asking questions in a group of people with similar experiences. Resuming presurgical social events and activities can enhance patients’ adaptation to a new way of life.
Ostomates and amputees have to cope not only with changes in physical appearance but with how their body functions and how they feel and perceive their body. They’re keenly aware of their changed appearance and are concerned about others’ perceptions of them. They may feel anxious and depressed related to body image; the degree of anxiety and depression may relate directly to their presurgical body image and activities. Many become anxious and fearful as they adapt to the prosthesis. (See Stages of grief by clicking the PDF icon above.)
Compared to amputees, ostomates may have more concerns about body image with sexual partners, because the stoma is, in a sense, a hidden amputation. In most cases, the stoma and pouch can be obscured visually from others. The amputee, on the other hand, has fewer options for hiding the missing body part.
To help patients cope with body-image problems, care providers must offer education, therapy, and counseling to help the patient accept and successfully adapt to the body-image change. The first step in this process may simply be to have the patient look at the stoma or stump, progressing to participation in prosthesis care.
Sexuality concerns
Many ostomates and amputees have difficulty resuming sexual activity after surgery. Although the stoma usually remains hidden from others, it’s observable to the ostomate and sex partner. Most patients require an adjustment period before they feel comfortable with a sex partner. They may fear that:
• the partner will reject them or no longer find them attractive
• they will experience loss of function and sensation
• they will experience pain or injury of the stoma.
They also may feel embarrassed, causing them to avoid sex. However, counselors can help couples discuss these concerns and resume a satisfactory sexual relationship. Ostomates and amputees and their partners may need counseling to resume a satisfactory sexual relationship. If they continue to have adjustment difficulties, referral to a trained sex counselor or psychologist may be indicated. Several studies show that appropriate counseling can help prevent complications and allow amputees and ostomates to continue to express their affection physically. (See Talking to patients about sexual problems by clicking the PDF icon above.)
Resuming sexual activity may be easier if the ostomate or amputee had a sex partner before surgery. However, males who experience postsurgical erectile dysfunction are less likely than other males to resume sexual activity. Counseling encourages postsurgical patients to focus more on the pleasurable feelings they and their partners feel, rather than on sexual performance. Body-image problems and inadequate sexual adjustment go hand in hand. (See Helping ostomates resume sex by clicking the PDF icon above.)
Team approach to patient education and counseling
In many parts of the country, a designated healthcare team manages amputees’ care and rehabilitation. But until recently, nurses were the only professionals certified to participate in ostomates’ care and rehabilitation. In fact, ostomates may represent a significant underserved population. A 2012 study found many ostomy patients didn’t receive consistent training and counseling from ostomy certified nurses. Only 13% of respondents reported they had regular visits with an ostomy certified nurse; 32% said they’d never received care from an ostomy nurse. Just over half (56%) indicated they saw an ostomy nurse when they thought it was necessary. The study also reported that 57% hadn’t seen an ostomy certified nurse in more than 1 year.
A team with specialized training to address ostomates’ physical and psychosocial needs might be able to provide the specialized care these patients need. The primary medical caregiver or general practitioner would serve as team leader and make appropriate referrals. The team should include a surgeon, ostomy- and amputee-trained nurses, a prosthetist or other healthcare provider trained in selection and fitting of prosthetic equipment and devices that affect function, a physical therapist, an occupational therapist, a social worker, a vocational counselor, a psychologist, caregiver or family members, support groups, and (last but not least) the patient.
The team approach might reduce hospital stays and promote patients’ return to their home environment. It also might encourage independence and enhance the success of long-term adaptation.
Focus on the future
Healthcare providers should encourage ostomates and amputees to focus on the future, not the past. Feeling comfortable with the prosthesis—the amputee’s artificial limb or the ostomate’s pouching system—is essential to adapting to a “new normal” way of life. Maintaining social relationships is important to adaptation as well. Mastering basic skills and adapting to changes in body function help improve the patient’s quality of life. Follow-up visits, phone contact, and access to a team of well-trained healthcare providers for patient education, rehabilitation, and long-term management are crucial to these patients’ successful adaptation and quality of life.
