Teaching ostomy patients to regain their independence

Wound Care Advisor

By Goranka Paula Bak, BSN, RN, ET, CWOCN

Every year, thousands of people of all ages have ostomy surgery in the United States. That means no matter where you work, you’re likely to care for patients with new ostomies and teach them to care for themselves. (See Why patients need ostomy surgery by clicking the PDF icon above.)
These patients present two challenges: staying up-to-date on ostomy equipment and procedures and having only 3 to 5 days after surgery to teach basic ostomy care to patients who are unlikely to be physically or emotionally ready to learn. This review and update of ostomy care should help you meet both challenges. Let’s start with the common types of stomas and ostomies.

Reviewing stoma types

The three common types of stomas are the end stoma, loop stoma, and double-barrel stoma. The patient’s surgeon decides on the most appropriate type based on the disease or injury, the amount of intestine available, and the patient’s health status.
To create an end stoma, the most common type, a surgeon creates a small opening in the abdominal wall, then resects the intestine and pulls it through the opening. Next, the surgeon turns the end of the intestine onto itself—somewhat like cuffing a sock—and sutures the stoma to the skin. Next to the stoma, the surgeon may create a mucous fistula, which secretes mucus from the nonfunctioning portion of the intestine.
A loop stoma is usually created for a temporary ostomy. The surgeon creates a small opening in the abdominal wall and pulls a loop of intestine through it. With an external rod or bridge placed under the loop to keep it from slipping back into the peritoneal cavity, the surgeon cuts the top of the loop to form the apex of the stoma. Next, the surgeon everts the intestine around the opening and sutures the stoma edges to the skin. After a few days, the rod is removed, and the stoma stays above skin level on its own.
Double-barrel stomas aren’t common in adults, but they are used frequently in neonates. For this type, a surgeon cuts through the bowel to create two separate end stomas, one to evacuate stool and the other to evacuate mucus. The two stomas can be placed next to each other, so one pouching system can be used for both. If the stomas are further apart, the patient may need two pouches. If mucus secretions are slight, you may be able to apply a nonadherent dressing after gently cleaning the stoma and peristomal skin, instead of using a pouch.
An ideal stoma protrudes above the skin surface and has a flat peristomal skin surface that allows the ostomy barrier to adhere to it. (See Characteristics of an ideal stoma by clicking the PDF icon above.) A healthy stoma is red and moist and looks like gum tissue. In fact, the entire alimentary canal from mouth to anus has the same type of tissue. Keep in mind that while cleaning a stoma, you’ll commonly see a small amount of bleeding, just as your gums may bleed when you brush your teeth too vigorously. If you note excessive bleeding, report it immediately.

Reviewing types of ostomies

The three most common types of ostomies you’ll see are a colostomy, an ileostomy, and a urostomy.
A surgeon creates a colostomy by making an opening in the large intestine and connecting it to the stoma. The location of the surgical opening will affect the consistency of the stool exiting the body through the stoma: The lower the opening, the firmer the consistency. A colostomy produces flatus because of the high bacterial content in the large intestine. A colostomy can be temporary or permanent, depending on the diagnosis and the patient’s ability to heal.
To create an ileostomy, a surgeon makes an opening in the small intestine and forms a stoma. Patients with ileostomies are prone to dehydration because a large amount of enzymatic fluid is discharged through the ileostomy instead of being absorbed in the disconnected large intestine. Teach your patient to be alert for the signs and symptoms
of dehydration—thirst; decreased urination; darker, concentrated urine; warm, flushed skin; fever; and malaise. Also, warn the patient to keep enzymatic effluent off the skin because it can quickly cause skin breakdown. As with a colostomy, an ileostomy may be temporary or permanent.
To create a urostomy, a surgeon removes the diseased bladder and uses a portion of resected small intestine to create a conduit. The ureters, which were connected to the bladder, are sutured into the resected small intestine so urine can exit the body through the stoma. Uros­tomies are permanent.

Choosing the right pouching system

An ostomy pouching system has two parts: an adhesive barrier that attaches to the skin around the stoma and a pouch connected to the barrier that collects effluent. Determining the right ostomy pouching system for your patients will depend on their needs and preferences. Let’s look at some of the important choices.
A pouching system may come in one or two pieces. With one-piece systems, the barrier (also called the wafer, flange, or baseplate) and pouch come as a single unit. (See One- and two-piece ostomy pouching systems by clicking the PDF icon above.) One-piece systems are easier to apply and more flexible. Plus, they’re flatter and thus more discreet.
With two-piece systems, the barrier and pouch are separate components that must be attached. Depending on the product, the patient may need to press the pouch onto the barrier or use a locking ring mechanism or an adhesive coupling system. Two-piece systems allow the patient to remove the pouch without removing the barrier. Also, a patient can apply a smaller pouch, such as a stoma cap or close-ended pouch, before exercise or intimate relations.
Today, ostomy pouching systems offer many options that weren’t available just a few years ago—options such as built-in, varying levels of convexity and integrated closures. Skin-friendly barriers now eliminate the need for accessory products, such as skin prep, ostomy powder, and stoma paste. By knowing the new options, you can help simplify the pouch application process for your patient and increase patient satisfaction.

Selecting barriers

Barriers may be cut-to-fit or precut. Cut-to-fit barriers are used during the postoperative period while the stoma size is changing and for oval or irregularly shaped stomas. Precut sizes are convenient for round stomas after they stabilize.
The choice of a barrier also depends on abdominal contours and the effluent consistency. A standard-wear barrier is appropriate for thicker output. An extended-wear barrier is better for loose or watery output and for problematic ostomies.
Convex barriers can be used to push down the peristomal skin and help the stoma project into the pouch. These barriers help ensure that the effluent goes into the pouch and not between the skin and the barrier, causing leakage.
For ostomies that are difficult to manage and frequently leak, you may select an ostomy belt. This device helps secure a convex pouching system by increasing its pressure. The plastic hooks at the end of the belt attach to the belt loops of the pouching system. Depending on the manufacturer, the belt loops may be on the barrier or the pouch.

Selecting pouches

Pouches can be transparent or opaque. Transparent pouches allow you to see the stoma postoperatively and allow patients to watch as they place the pouch over the stoma. Opaque pouches, of course, have the advantage of concealing the effluent.
Some pouches have filters. Colostomy patients usually prefer filtered pouches because they eliminate the need to burp the pouch to remove gas. Ileostomy output is usually watery, so the charcoal filters may get wet and quit working.
The appropriate type of pouch closure also varies, depending on the type of output and the patient’s needs and preferences. A patient with a colostomy or ileostomy needs a drainable pouch. Newer clamps and integrated closures can make closing the pouch easier for the patient.
Close-ended pouches are available for patients who empty their pouch once or twice a day. Reimbursement guidelines for Medicare, which most insurance companies follow, allow 60 close-ended pouches a month. Thus, someone who empties once or twice a day will have enough pouches.
Patients with urostomies use pouches with spigots on the end to allow for urine drainage.
Urostomy pouches can be connected to a continuous urinary drainage bag at bedtime or to a leg bag during the day for those in a wheelchair.

Dealing with complications

Report the following postoperative complications to the surgeon and the ostomy clinician caring for the patient:
• allergic reaction
• candidiasis
• contact dermatitis
• folliculitis
• ischemic or necrotic stoma
• mechanical irritation
• mucocutaneous separation
• parastomal hernia
• prolapse.

Many complications result from surgical technique or the patient’s disease status, but complications also result from an incorrect fit or an ostomy that frequently leaks. To determine why and where leakage occurred, examine the back of the barrier. If leakage results from a flush or recessed stoma or an irregular surface around the stoma, the patient may need a convex barrier. Or the patient may need a convex barrier and an ostomy belt.
Remember that a firm abdomen requires a soft, flexible barrier that conforms to the abdominal contours. A soft belly, on the other hand, may need the rigidity of a convex barrier to help the stoma empty into the pouch.
For weepy, extremely denuded skin, apply ostomy powder, brush off the excess, and dab an alcohol-free skin seal­ant, such as No-Sting by 3M, on the area. Allow the area to air-dry before applying the barrier.

Discharge planning and patient teaching

Because the postoperative length of stay is short, start preparing for discharge and teaching the pouch-change procedure at your first hospital encounter with the patient. Teaching the patient at each encounter creates a continuum of care throughout hospitalization and recovery. If possible, include the caregiver. (See Teaching your patient to change an ostomy pouch by clicking the PDF icon above.) Before discharge, give the patient two or three ostomy pouches to take home, step-by-step printed instructions on applying pouches, a list of supplies the patient will need, and a list of ostomy product suppliers in the area.
Also, teach the patient about complications, activity, diet, and drug therapy and provide the names of local support groups. (See Finding support by clicking the PDF icon above.)

Complications at home

Tell the patient to call the physician if any of the following occurs: fever, increased pain or discomfort, diarrhea, dehydration, or signs and symptoms of infection at the surgical site. The patient should also call the physician if there’s no output from the stoma for more than 24 hours.
Patients with urostomies who develop the following signs and symptoms may have a urinary tract infection: fever, chills, abdominal or retroperitoneal pain, and bloody, cloudy, or foul-smelling urine. Clear urine with mucus shreds is normal.

Increasing activity

Explain that after surgery the patient should feel a little bit stronger every day. Teach the patient to alternate rest and activity periods and to increase the activity period a little each day while building endurance. Refer the patient to the physician for clearance to resume exercise and sexual relations.

Dietary considerations

After ostomy surgery, your patient will start on a clear liquid diet and progress to a normal, preoperative diet. The patient should reintroduce one food at a time to help determine if it’s well tolerated. High-fiber foods should be introduced slowly.
Tell your patient to expect his or her body to tolerate the food as it did before surgery: if onions caused gas before surgery, they will do so after surgery, too, but the stoma will expel the gas. Make the patient aware of other gas-forming foods, such as hard-boiled eggs, spicy foods, fish, dried beans, carbonated beverages, and beer.
Tell the patient to chew food well and to drink plenty of liquids, which will prevent blockage. Explain the importance of hydration to avoid constipation, dehydration, and urinary tract infection. To prevent dehydration, ileostomy patients who are not on fluid restriction should drink 64 ounces of fluid a day. Teach these patients to replace fluids by drinking a glass of water every time they empty their pouches.

Drug therapy

Tell the patient to adhere to the prescribed regimen and to call the physician before using any new drugs. Instruct patients with ileostomies not to take laxatives because they may become dehydrated. These patients should tell their pharmacist that they have an ileostomy, so the proper form of prescription drugs can be ordered. Extended-release tablets will not break down in time and may be found in the pouch.

Rewarding work

Keeping up with the changes in ostomy equipment and care and teaching new ostomy patients the skills they need can be challenging. But helping these patients regain the confidence and learn the skills they need to improve their quality of life makes the rewards much greater than the challenges.

Mission possible: Getting Medicare reimbursement for wound care in acute-care settings

Wound Care Advisor

By Susan Reinach-Lannan, BSOM

In the current healthcare environment, wound care practitioners need to capitalize on all available reimbursement avenues for care delivery and wound care supplies and dressings. And when it comes to reimbursement, there’s one constant: The rules change constantly. Whether these changes always benefit the patient is questionable. Nowhere is this more evident than in acute-care settings. Clinicians constantly are challenged to make sure their patient-care decisions comply with current Medicare reimbursement guidelines. (And if you’re not sure about today’s guidelines, be prepared for the guidelines to change tomorrow.) (more…)

Necrotizing fasciitis: Frightening disease, potentially grim prognosis

Wound Care Advisor

By Lydia Meyers, BSN, RN, CWCN

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.

Get positive results with negative-pressure wound therapy

Wound Care Advisor

By Ronald Rock, MSN, RN, ACNS-BC

Complex wound failures are costly and time-consuming. They increase length of stay and contribute to morbidity and mortality in surgical patients. Negative-pressure wound therapy (NPWT)—a common adjunct to wound-care therapy—is used to accelerate wound healing in all fields of surgery. Using a vacuum device and wound-packing material, it applies subatmospheric pressure to complex wounds.
But NPWT alone doesn’t ensure adequate wound healing. Many physiologic factors—including infection, excessive moisture, nutrition, and medications—influence wound-healing success. Failure to account for these factors or improper application of NPWT can limit patient outcomes and cause debilitating complications.
For clinicians, applying and establishing an airtight seal on a complex wound is among the most dreaded, time-consuming, and challenging NPWT-related tasks. Simply applying NPWT material under layers of transparent drape may delay wound healing or exacerbate the wound. This article provides tips on safe application of NPWT to enhance the outcomes of patients with complex wounds.

 Consider wound location

Wounds on the body’s anterior surfaces are less susceptible to the forces of pressure, friction, and shear than those on posterior and lateral surfaces. Posterior and lateral wounds commonly require posterior off­loading or repositioning the patient in bed to reduce or eliminate direct pressure. This can be done with judicious and frequent patient turning using a specialty bed or support surface.
Bridge a posterior or lateral wound to an anterior surface by placing the drainage collection tubing to a nonpressure-bearing surface away from the wound. Bridging keeps the tubing from exerting pressure on intact skin and decreases the risk of a pressure ulcer. To create the bridge, cut foam into a single spiral of 0.5 to 1 cm, or if using gauze, fold gauze into 8 single layers.
Place the spiraled foam or gauze layers onto the drape, ensure the bridge is wider than the collection tubing disc, and secure it with an additional drape. Next, apply the NPWT collection tubing on the end of the bridge away from the wound. A wide bridge under the collection tubing disc will minimize the potential for periwound breakdown when negative pressure is initiated. You may modify this spiraling technique by varying the width of the foam to fill undermining and wounds of irregular configuration and depth.

 Protect the periwound

An intact periwound may break down from exposure to moisture, injury from repetitive removal of a transparent drape, or NPWT material coming in contact with skin. Skin protection is critical in preventing additional breakdown stemming from contact with potentially damaging material.
Transparent drapes are designed to permit transmission of moisture vapor and oxygen. Avoid using multiple layers of transparent drapes to secure dressings over intact skin, as this can decrease the transmission of moisture vapor and oxygen, which in turn may increase the risk of fungal infection, maceration, and loss of an intact seal.
Periwound maceration also may indicate increased wound exudate, requiring an increase in negative pressure. Conversely, an ecchymotic periwound may indicate excessively high negative pressures. If either occurs, assess the need to adjust negative pressure and intervene accordingly. Reassess NPWT effectiveness with subsequent dressing changes.
Apply a protective liquid skin barrier to the periwound and adjacent healthy tissue to help protect the skin surface from body fluids. The skin barrier also helps prevent stripping of fragile skin by minimizing shear forces from repetitive or forceful removal of transparent drapes. Excessive moisture can be absorbed by using a light dusting of ostomy powder sealed with a skin barrier. A “window pane” of transparent drape or hydrocolloid dressing around the wound also can protect surface tissue from contactwith NPWT material and prevent maceration.

 Avoid creating rolled wound edges

In the best-case scenario, epithelial tissue at the wound edge is attached to the wound bed and migrates across healthy granulation tissue, causing the wound to contract and finally close. With deep wound environments that lack moisture or healthy granulation tissue, the wound edges may roll downward and epibole may develop. Epibole is premature closure of the wound edges, which prevents epi­thelialization and wound closure when it comes in contact with a deeper wound bed. (See Picturing epibole by clicking the PDF icon above.)
Materials used in NPWT are primarily air-filled. Applying negative pressure causes air removal, leading to wound contraction by pulling on the wound edges—an action called macrostrain. Without sufficient NPWT material in the wound, macrostrain can cause the wound to contract downward and the wound edges to roll.
Ensure that enough NPWT material has been applied into the wound to enhance wound-edge approximation and avoid creating a potential defect as the wound heals. Before NPWT begins, material should be raised 1 to 2 cm above the intact skin. Additional material may be needed with subsequent changes if the NPWT material compresses below the periwound. The amount of NPWT material needed to remain above the periwound once NPWT starts varies with the amount of material compressed and the wound depth.

 Reduce the infection risk

To some degree, all wounds are contaminated. Usually, the body’s immunologic response is able to clear bacterial organisms and wound healing isn’t delayed. But a patient who has an infection of a complex wound needs additional support.
Systemic antibiotics alone aren’t enough because they’re selective for specific organisms and don’t reach therapeutic levels in the wound bed. In contrast, topical anti­microbial adjuncts, such as controlled-release ionic silver, provide broad-spectrum antimicrobial coverage against fungi, viruses, yeasts, and gram-negative and gram-positive bacteria, including methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci.
Consider using controlled-release ionic silver for a wound known to be infected or at risk for infection due to its location or potential urine or fecal contamination. To be bactericidal, ionic silver must be in concentrations of at least 20 parts per million; also, it must be kept moist and must come in direct contact with infected wound bed. At lower concentrations, organisms may develop resistance. Ionic silver has no known resistance or contraindications. Dressings using it come in several forms, including a hydrogel sheet, perforated sheet, cavity version, and semiliquid hydrogel. Be sure the form you choose doesn’t occlude the NPWT material and compromise therapy. (See NPWT for a patient with necrotizing fasciitis by clicking the PDF icon above.)

Obtain a negative-pressure environment

One of the most daunting aspects of NPWT is obtaining and maintaining a good seal—in other words, avoiding the dreaded leak. Preventive skin measures may contribute to a poor seal; skin-care products containing glycerin, surfactant, or dimethicone may prevent adequate adhesion of NPWT drapes. Body oil, sweat, and hair may need to be minimized or removed.
To avoid leaks, don’t overlook the obvious—loose connections, a loose drainage collection canister, exposed NPWT material, and skinfolds extending beyond the transparent drape. Tincture of benzoin (with or without a thin hydrocolloid dressing) increases tackiness to enhance the adhesive property of a transparent drape on the diaphoretic patient and on hard-to-drape areas, such as the perineum. But be sure to use tincture of benzoin with discretion, as it may remove fragile periwound tissue when the dressing is removed.
Ostomy paste products can serve as effective filler. These pliable products can be spread into position to obtain a secure seal under the transparent drape in hard-to-seal areas, such as the perineum. Pastes remain flexible and can be removed without resi­due. Temporarily increasing NPWT pressure to a higher setting may help locate a subtle leak or provide enough negative pressure to self-seal the leak. Once the leak resolves, remember to return the pressure to the ordered setting.

 Knowledge optimizes healing

It’s important to be aware of potential complications of NPWT (See Take care with NPWT by clicking on the PDF icon above). However, when applied correctly, NPWT is an effective option for managing complex wounds. Recognizing and managing potential complications at the wound site, ensuring periwound protection, minimizing epibole formation, and preventing wound infection can result in a better-prepared wound bed and promote optimal healing.

Providing wound care in the home: An option to explore

Wound Care Advisor

By Connie Johnson, RN, BSN, WCC, LLE, DAPWCA

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.

“We don’t have a Doppler”

Wound Care Advisor

By: Donna Sardina, RN, MHA, WCC, CWCMS, DWC

Venous leg ulcers are the most common cause of lower extremity ulcers, affecting 1% of the U.S. population (approximately 3 million people). Annual treatment costs for venous disease in this country range from $1.9 to $3.5 billion.

The gold standard for venous ulcer treatment includes moist wound healing and compression therapy. But before compression wraps are applied, we must determine if adequate arterial blood flow exists—or consequences could be life-threatening.

Raise your hand if you know what ABI is. Now raise your hand if you routinely obtain ABIs for patients. I’ve been asking these questions at wound care seminars around the country for the last 10 years, and the answers are always the same:
Between 50% and 95% of the audience know what an ABI is, but only 1% to 2% say they perform the ABI test. My next question is “Why not?”

The ABI (ankle brachial index) is a non­invasive screening test performed with a handheld vascular Doppler and a blood pressure cuff. This simple test helps determine if you can safely apply compression therapy, aids diagnosis of peripheral arterial disease, and even helps monitor the efficacy of therapeutic interventions.

Numerous standard practice guidelines from various organizations recommend obtaining ABIs to determine arterial blood flow. These organizations include the American College of Cardiology, American Heart Association, American Diabetes Association, Society for Vascular Nursing, Wound Ostomy Continence Nurses, Society for Vascular Medicine, U.S. Preventive Services Task Force, and World Union of Wound Healing Societies.

Instructions for most compression therapy products include indications for Doppler ABI readings above 0.8. So if you don’t get an ABI reading, how can you safely apply these products? A report by Allie and colleagues found that more than 50% of lower extremity amputations occur without previous vascular testing of any type, including ABI.

So why aren’t more practitioners obtaining ABIs? The leading answer: “We don’t have a Doppler.” I understand the dilemma of not having equipment or the funds to get the equipment. But do we want to tell a patient who has just lost her leg, “Oh, sorry. We didn’t have a Doppler”?

It’s our responsibility and duty as WCCs, wound care experts, and health care clinicians to ensure we provide the highest standard of care for patients with venous leg ulcers. So communicate with management, explaining what you need and why you need it. Work with your medical supply company for an extended payment plan. Hold a fundraiser. Consider using the alternative Lanarkshire Oximetry Index procedure. Or send the patient to a wound clinic or other healthcare provider who can perform the test.

It’s time to step it up and take greater accountability—and to no longer use the excuse “We don’t have a Doppler.”
