Practical Issues in Wound, Skin and Ostomy Management
Wound pain can have a profound effect on a person’s life and is one of the most devastating aspects of living with a wound. In addition to pharmaceutical options, wound care clinicians should consider other key aspects of care that can alleviate pain. Here is a checklist to ensure you are thorough in your assessment.

Read MoreEvery 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.
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.
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.
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.
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.
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.
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.
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.)
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.
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.
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.
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.
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.

Read MoreIn 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…)
Read MoreNecrotizing 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:
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.
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.
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.)
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.
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.
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.)
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.
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.

Read MoreComplex 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.
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.
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.
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.
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.)
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.
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.

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

Read MoreFoot infections in patients with diabetes usually start in a wound, most often a neuropathic ulceration. So clinicians can better manage diabetic foot infections, the Infectious Diseases Society of America (IDSA) published “2012 Infectious Diseases Society of America Clinical Practice Guideline for the Diagnosis and Treatment of Diabetic Foot Infections” in the June 15 Clinical Infectious Diseases.
The guideline updates IDSA’s 2004 diabetic foot infections guideline. It focuses on appropriate therapy, including debridement of dead tissue, appropriate antibiotic therapy, removing pressure on the wound, and assessing (and potentially improving) blood flow to the foot. The guideline also provides suggestions regarding when and how long antibiotics should be administered for soft-tissue and bone infections.
When diagnosing a diabetic patient with foot infection, the guideline recommends clinicians evaluate the patient at three levels—the patient as a whole, the affected foot or limb, and the infected wound. The guideline also provides advice on when and how to culture diabetic foot wounds.

In obese patients with uncontrolled type 2 diabetes, bariatric surgery and 12 months of medical therapy significantly improved glycemic control compared to those who received only medical therapy, according to a study in The New England Journal of Medicine. “Bariatric surgery versus intensive medical therapy in obese patients with diabetes” was a randomized, nonblinded, single-center trial that included 150 patients in three groups: medical therapy only, medical therapy and Roux-en-Y gastric bypass, and medical therapy and sleeve gastrectomy.
Although glycemic control improved for all three groups, those who received bariatric surgery had better control. Use of drugs to lower glucose, lipid, and blood-pressure levels decreased significantly after both surgical procedures but increased in patients receiving medical therapy only. No deaths or life-threatening complications occurred.
The U.S. Department of Health and Human Services (HHS) has launched a web-based tool for monitoring the performance of the healthcare system. The Health System Measurement Project gives providers and the public the ability to examine datasets from across the federal government that span specific topic areas, such as access to care, vulnerable populations, prevention, and quality. Users can also view indicators by population characteristics, such as age, sex, income level, insurance coverage, and geography.
According to a study published in Archives of Internal Medicine, percutaneous endoscopic gastrostomy (PEG) tubes may increase the risk of pressure ulcers in nursing home patients with advanced cognitive impairment.
Researchers found that hospitalized patients who receive a PEG tube were 2.27 times more likely to develop a new pressure ulcer and those with a pressure ulcer were less likely to have it heal when they had a PEG tube. “Our findings regarding the risk of developing new stage 2 or higher pressure ulcers suggest that PEG feeding tubes are not beneficial, but in fact they may potentially harm patients,” conclude the researchers in “Feeding tubes and the prevention or healing of pressure ulcers.”
The Agency for Healthcare Research and Quality (AHRQ) offers a toolkit designed to help hospitals understand AHRQ’s quality indicators (QIs). “AHRQ Quality Indicators™ Toolkit for Hospitals” includes steps for improvement, how to sustain change, and different tools for different audiences. Clinicians can also access audio interviews that provide information on how to use the tools and engage stakeholders and staff in QI efforts, and a recording of a webinar on the toolkit.
Researchers at Tufts University have developed the first all-polymeric bone scaffold material that is fully biodegradable and capable of providing significant mechanical support during repair. The material could improve the way bones and tissues are repaired after an accident or following disease effects.
The new technology uses micron-size silk fibers to reinforce a silk matrix, much as steel rebar reinforces concrete. The study, “High-strength silk protein scaffolds for bone repair,” published in Proceedings of the National Academy of Sciences, found that the scaffold material is significantly less strong than normal bone, but it may play a role as a temporary biodegradable support for the patient’s cells to grow.
June’s Wounds International includes “International consensus: Appropriate use of silver dressings in wounds.”
A meeting of an international group of experts, convened by Wounds International, met in December 2011 to compile the consensus guidelines, which describe the patients who are most likely to benefit from silver dressings and how to use the dressings appropriately.
The guidelines recommend that silver dressings be used “in the context of accepted standard wound care for infected wounds or wounds that are at high risk of infection or reinfection.” Another recommendation is to use silver dressings for 2 weeks, then evaluate the wound, patient, and management approach before deciding whether to continue using the dressing or if a more aggressive intervention such as antibiotics would be better.
Injections of ixmyelocel-T in patients with lower extremity critical limb ischemia (CLI) who aren’t candidates for revascularization can prolong the time until treatment failure, according to a study in Molecular Therapy. Time to treatment failure was defined as major amputation, all-cause mortality, doubling of total wound surface area from baseline, or de novo gangrene. The double-blind, placebo-controlled RESTORE-CLI trial found that the adverse event rates were similar in the two groups.
A new skin patch destroyed facial basal cell carcinoma cells in 80% of patients, according to a study reported at the Society of Nuclear Medicine’s 2012 Annual Meeting.
Each of the 10 patients with facial basal cell carcinoma received a custom-made and fully sealed phosphorus-32 skin patch, a radiation spot-treatment in the form of a patch. Each patient was treated for 3 hours on the first day; the patches were reapplied on the fourth and seventh days after the first treatment for another 3 hours each. Three years after treatment, 8 of 10 patients were cancer-free.
The patients had lesions near the eyes, the nose, and forehead—areas more difficult to operate on, especially if skin grafting is needed later.
The average body-mass index (BMI) in obese patients with lymphedema was significantly greater than BMIs of obese patients without lymphedema, according to correspondence in The New England Journal of Medicine. The authors conclude, “Our findings suggest that obesity…may be a cause of lower-extremity lymphedema.”
“Lower-Extremity Lymphedema and Elevated Body-Mass Index” included 15 obese patients with bilateral lower-extremity enlargement who were referred to the authors’ center. Of the 15, five were diagnosed with lymphedema by lymphoscintigraphy.

Read MoreWound care has come a long way in just a few decades. With our expanded knowledge of wound healing and recent advances in treatment, we’re now able to assess wounds more accurately, recognize wound-related problems sooner, provide better interventions, and reduce morbidity.
To bring you up to date on current evidence-based wound management, this article focuses on assessing patients with chronic wounds, optimizing wound healing with effective wound-bed preparation, and selecting an appropriate dressing.
Developing an appropriate plan of care hinges on conducting a thorough, accurate evaluation of both the patient and the wound. The first step is to determine whether the wound is acute or chronic.
• A chronic wound is one that fails to heal within a reasonable time—usually
3 months.
• An acute wound heals more quickly, causing minimal functional loss in the part of the body with the wound.
Identifying the cause of the wound also is essential. If the wound etiology is unknown, explore the patient’s medical history (including medication history) for clues to possible causes. Also review the patient’s history for conditions that could impede wound healing. (See What factors hamper healing? by clicking the PDF icon above)
Other important aspects of assessment include evaluating the patient’s nutritional status, quantifying the level of pain (if present), and gauging the patient’s self-care abilities.
Conduct a general head-to-toe physical examination, focusing on the patient’s height, weight, and skin characteristics.
On admission, the patient’s height and weight should be measured to ensure appropriate nutritional and pharmacologic management. After a weight gain or loss, various factors may complicate wound healing. For instance, involuntary weight loss and protein-energy malnutrition may occur in both acute-care and long-term-care patients.
Especially note trends in your patient’s weight. For a long-term-care patient, a 5% weight loss over 30 days or a 10% loss over 180 days is considered involuntary. Arrange for a nutritional consult for any patient with an involuntary weight loss, as adequate nutrition is essential for general well-being and wound healing. (See A wound on the mend by clicking the PDF icon above.)
Evaluate the patient’s skin color in light of ethnic background. If you note erythema—especially on a pressure point over a bony prominence—examine this area carefully for nonblanching erythema. Keep in mind that darkly pigmented skin doesn’t show such erythema and subsequent blanching, yet the patient may still be in jeopardy. So in dark-skinned patients, check for differences in skin color, temperature, or firmness compared to adjacent tissue; these differences may signify skin compromise.
Generally, healthy skin feels smooth and firm and has an even surface and good turgor (elasticity). To test turgor, gently grasp and pull up a fold of skin on a site such as the anterior chest below the clavicle. Does the skin return to place almost immediately after you release it, or does it stand up (“tent”)? Tenting indicates dehydration. But keep in mind that skin loses elasticity with age, so elderly patients normally have decreased turgor.
With normal circulatory status, the skin is warm and its temperature is similar bilaterally. Areas of increased warmth or coolness suggest infection or compromised circulation. Be sure to check the temperature of skin surrounding the wound.
Proper wound assessment can significantly influence patient outcome. Measure the wound carefully and document the condition of the wound bed. Remember that accurate descriptions are essential for guiding ongoing wound care. Repeat wound measurement and wound-bed assessment at least weekly, after the wound bed has been cleaned and debrided.
Keep in mind that assessing a chronic wound can be challenging. Wounds commonly have irregular shapes that can change quickly. Also, the multiple clinicians caring for the same patient may each describe the wound a bit differently.
Note the precise anatomic location of the wound, as this can influence the wound care plan. A venous ulcer on the lower leg, for instance, requires different care than an arterial ulcer in the same site or a pressure ulcer on the ischium.
Use a paper or plastic measuring device to measure wound circumference and depth in centimeters (cm) or millimeters (mm). To promote accurate assessment of healing, be sure to use the same reference points each time you measure the wound.
You can use several methods to measure circumference. The most commonly used method of measurement is done in the head to toe direction. Measure the wound at its greatest length in that direction & measure the width at a 90 degree angle, at the widest point of the wound. Then multiply these two measurements (greatest length x greatest width) to obtain the total wound area. Although such linear measurements are imprecise, they yield gross information relative to wound healing when repeated over time.
Classify wound depth as partial thickness or full thickness.
• Partial-thickness wounds are limited to the skin layers and don’t penetrate the dermis. They usually heal by reepithelialization, in which epidermal cells regenerate and cover the wound. Abrasions, lacerations, and blisters are examples of partial-thickness wounds.
• Full-thickness wounds involve tissue loss below the dermis.
(Note: Pressure ulcers usually are classified by a four-stage system and diabetic foot ulcers by a grading system. Both systems are beyond this article’s scope.)
Measure and record wound depth based on the deepest area of tissue loss. To measure depth, gently place an appropriate device (such as a foam-tipped applicator) vertically in the deepest part of the wound, and mark the applicator at the patient’s skin level. Then measure from the end of the applicator to the mark to obtain depth.
Inspect for and document any erythema, edema, or ecchymosis within 4 cm of the wound edges, and reevaluate for these signs frequently. Because compromised skin near the wound is at risk for breakdown, preventive measures may be necessary.
Document viable tissue in the wound bed as granulation, epithelial, muscle, or subcutaneous tissue. Granulation tissue is connective tissue containing multiple small blood vessels, which aid rapid healing of the wound bed; appearing red or pink, it commonly looks shiny and granular. Epithelial tissue consists of regenerated epidermal cells across the wound bed; it may be shiny and silvery.
Check for nonviable tissue (also called necrotic, slough, or fibrin slough tissue), which may impede wound healing. It may vary in color from black or tan to yellow, and may adhere firmly or loosely to the wound bed. (See Picturing a necrotic wound by clicking the PDF icon above.)
Be sure to document the range of colors visible throughout the wound. Identify the color that covers the largest percentage of the wound bed. This color—and its significance—guide dressing selection.
Document the amount, color, and odor of exudate (drainage) in the wound. Exudate with high protease levels and low growth factor levels may impede healing.
If the wound is covered by an occlusive dressing, assess exudate after the wound has been cleaned. Describe the amount of exudate as none, minimal, moderate, or heavy.
Describe exudate color as serous, serosanguineous, sanguineous, or purulent. Serous exudate is clear and watery, with no debris or blood present. Serosanguineous exudate is clear, watery, and tinged pink or pale red, denoting presence of blood. Sanguineous exudate is bloody, indicating active bleeding. Purulent exudate may range from yellow to green to brown or tan.
Describe wound odor as absent, faint, moderate, or strong. Note whether the odor is present only during dressing removal, if it disappears after the dressing is discarded, or if it permeates the room.
Wound edges indicate the epithelialization trend and suggest the possible cause and chronicity of the wound. The edges should attach to the wound bed. Edges that are rolled (a condition called epibole) indicate a chronic wound, in which epithelial cells are unable to adhere to a moist, healthy wound bed and can’t migrate across and resurface the wound.
Gently probe around the wound edges and in the wound bed to check for undermining and tracts. Undermining, which may occur around the edges, presents as a space between the intact skin and wound bed (resembling a roof over part of the wound). It commonly results from shear forces in conjunction with sustained pressure. A tract, or tunnel, is a channel extending from one part of the wound through subcutaneous tissue or muscle to another part.
Measure the depth of a tract or undermining by inserting an appropriate device into the wound as far as it will go without forcing it. Then mark the skin on the outside where you can see or feel the applicator tip. Document your findings based on a clock face, with 12 o’clock representing the patient’s head and 6 o’clock denoting the feet. For instance, you might note “2.0-cm undermining from 7:00 to 9:00 position.”
Ask the patient to quantify the level of pain caused by the wound, using the pain scale designated by your facility. Find out which pain-management techniques have relieved your patient’s pain in the past; as appropriate, incorporate these into a pain-management plan. Reevaluate the patient’s pain level regularly.
An evolving science, wound-bed preparation is crucial for minimizing or removing barriers to healing. The goal is to minimize factors that impair healing and maximize the effects of wound care. The key elements of wound-bed preparation are controlling bioburden and maintaining moisture balance. (For online resources on wound-bed preparation and other wound-care topics, see Where to get more information by clicking the PDF icon above.)
Necrotic tissue and exudate harbor bacteria. A wound’s bioburden—the number of contaminating microbes—contributes to poor healing. All chronic wounds are considered contaminated or colonized, but not necessarily infected. In a colonized wound, healing is impeded as bacteria compete for nutrients; also, bacteria have harmful byproducts. To control bioburden, the wound must be cleaned and necrotic tissue must be debrided.
Cleaning the wound. Clean the wound before assessing it and applying a dressing. Use a noncytotoxic agent (typically, potable water, normal saline irrigating solution, or an appropriate wound-cleaning agent). Antiseptic solutions generally aren’t recommended for wound irrigation or dressings because they’re toxic to fibroblasts and other wound-repairing cells. If you must use such a solution, make sure it’s well diluted.
To ensure gentle cleaning or irrigation, pour solution over the wound bed or gently flush the wound with solution (using a 60-mL catheter-tip syringe) until the drainage clears. Know that pressurized irrigation techniques and whirlpool therapy aren’t recommended for wound cleaning because they disturb cell proliferation in the wound bed.
Debriding the wound. Debridement removes slough and necrotic tissue. Nonselective debridement techniques remove any type of tissue within the wound bed, whereas selective methods remove only necrotic tissue. (See Wound debridement techniques by clicking the PDF icon below.)
To maintain moisture balance in the wound bed, you must manage exudate and keep the wound bed moist. The proper dressing (which may stay in place for days or longer) supports moist wound healing and exudate management. To minimize fluid pooling, a drain may be inserted into the wound. Negative-pressure wound therapy also may aid removal of excess exudate.
The wound dressing plays a major role in maintaining moisture balance. Dressing selection is challenging because of the large number and variety of dressings available. Each product has specific actions, benefits, and drawbacks, so determining which dressing best suits the patient’s needs is a multifaceted process.
Dressing choice depends on such factors as wound type and appearance, exudate, presence or absence of pain, and required dressing change frequency. (See Dressings Options by clicking the PDF icon above.)
In a traditional dressing, gauze is applied in layers. The initial (contact) layer in the wound bed absorbs drainage and wicks it to the next layer; most often, this layer consists of woven cotton gauze or synthetic gauze. Remove the gauze gently, because it may be stuck to the wound or incision (especially if the gauze is cotton). For easier removal, moisten the dressing with normal saline solution to loosen it.
With a traditional dressing, the cover layer or secondary dressing is an abdominal pad with a “no-strike-through” layer next to the outside of the dressing. Be aware that wet-to-dry dressings are highly discouraged for their nonselective debriding effect and inability to provide a moist wound bed.
Reassess the patient’s wound at least weekly (after preparing the wound bed and dressing the wound) to determine healing progress. Keep in mind that wound-care management is a collaborative effort. Once you’ve assessed the patient, discuss your findings and subsequent wound management with other members of the team.
Getting wiser about wound care will help your patients achieve good outcomes. Poor wound healing can be frustrating to patients, family members, and healthcare providers alike. Chronic wounds may necessitate lifestyle changes and lead to severe physical consequences ranging from infection to loss of function and even death. By performing careful assessment, tailoring patients’ wound care to wound etiology, and using evidence-based protocols to manage wounds, you can promote speedier wound healing, help lower morbidity, and improve quality of life.

Read MoreMoisture-related skin breakdown has been called many things-perineal dermatitis, irritant dermatitis, contact dermatitis, heat rash, and anything else caregivers could think of to describe the damage occurring when moisture from urine or stool is left on the skin. At a 2005 consensus conference, attendees chose the term incontinence-associated dermatitis (IAD).
IAD can be painful, hard to properly identify, complicated to treat, and costly. It’s part of a larger group of moisture-associated skin damage that also includes intertrigo and periwound maceration. IAD prevalence and incidence vary widely with the care setting and study design. Appropriate diagnosis, prompt treatment, and management of the irritant source are crucial to long-term treatment.
IAD stems from the effects of urine, stool, and containment devices on the skin. The skin’s pH contributes to its barrier functions and defenses against bacteria and fungus; ideal pH is 5.0 to 5.9. Urine pH ranges from 4.5 to 8.0; the higher range is alkaline and contributes to skin damage.
Skin moisture isn’t necessarily damaging. But when moisture that contains irritating substances, such as alkaline urine, contacts the skin for a prolonged period, damage can occur. Urine on the skin alters the normal skin flora and increases permeability of the stratum corneum, weakening the skin and making it more susceptible to friction and erosion. Fecal incontinence leads to active fecal enzymes on the skin, which contribute to skin damage. Fecal bacteria can penetrate the skin, increasing the risk of secondary infection. Wet skin has a lower temperature than dry skin; wet skin under a pressure load has less blood flow than dry skin.
Containment devices, otherwise known as adult diapers or briefs, are multilayer disposable garments containing a superabsorbent polymer. The polymer is designed to wick and trap moisture in the containment device. This ultimately affects the skin by trapping heat and moisture, which may cause redness and inflammation that can progress to skin erosion. This trapping can lead to increased pressure against the skin, especially if the device has absorbed liquid and remains in contact with the skin.
IAD is categorized as mild, moderate, or severe. (See Picturing IAD by clicking the PDF icon above.)
Screen the patient’s skin for persistent redness, inflammation, rash, pain, and itching at least daily. To differentiate IAD from pressure ulcers, keep in mind that:
The three essentials of IAD prevention are to cleanse, moisturize, and protect.
If the treatment protocol fails, the patient should be referred to an appropriate skin care specialist promptly.
To help prevent urine or stool from contacting the patient’s skin, consider using a male external catheter, a female urinary pouch, a fecal pouch, or a bowel management system. Avoid containment devices. If the patient has a containment pad, make sure it’s highly absorbent and not layered, to decrease pressure under the patient.
A comprehensive multidisciplinary approach to IAD is essential to the success of any skin care protocol. Identify skin care champions within your facility and educate them on IAD. Incorporating administrators, physicians, nursing staff, therapists, and care assistants makes implementation of protocols and algorithms within an institution seamless.
Administrators support the skin care program in the facility, including authorizing a budget so product purchases can be made. The certified wound clinician is the team expert regarding skin care, incontinence, prevention, and product recommendation. The physician oversees protocol development and evaluates and prescribes additional treatment when a patients fails to respond to treatment algorithms. Nursing staff identify patients at risk, incorporate the algorithm into the patient’s plan of care, and direct care
assistants. Therapists address function, strength, and endurance issues to improve the patient’s self-care abilities in activities of daily living to manage or prevent episodes of incontinence.
In severe inflammation, topical dressings, such as alginates and foam dressings, may be used along with topical corticosteroids. In complex IAD, antifungals or antibiotics may be required if a secondary fungal or bacterial infection is suspected.
Additional diagnostic tests may be done to identify and treat secondary infections. These tests may include skin scraping, potassium hydroxide test or Gram’s stain for fungal components, or a swab culture and sensitivity for bacterial infections. If your patient has a suspected secondary fungal or bacterial infection, use appropriate treatments for the full course of recommended therapy. In severe secondary fungal infection, an oral agent may be added to topical therapy. If cost is a concern, consider using a pharmacy knowledgeable about compounding for topical combination therapies.
For assessment and treatment of under-lying incontinence, refer the patient to a continence specialist if appropriate. Teach the patient strategies for managing incontinence through dietary measures, toileting programs, pelvic-floor muscle training, clothing modification, and mobility aids.

Read MoreIn the modern world of wound care, there are many treatment options. Surprisingly though, we are still seeing orders for those dreaded wet-to-dry dressings. Using a wet-to-dry dressing involves placing moist saline gauze onto the wound bed, then allowing it to dry and adhere to the tissue in the wound bed. Once the gauze is dry, the clinician removes the gauze, with force often required. This has to be repeated every 4 to 6 hours. Wet-to-dry dressings are a nonselective debridement method that harms good tissue as well as removes necrotic tissue. It keeps the wound bed at a cool temperature and it at risk for bacterial invasion, as bacteria can penetrate up to 64 layers of gauze! It’s one of the most painful procedures for our patients, and this was one treatment that as a nurse I never wanted to do. In fact, I have heard of nurses who would remoisten the gauze before removal to make the treatment more bearable for patients.
Are you seeing a lot of these dressing still used in current practice? What types of settings are they still being used in consistently? How are you dealing with the prescribing clinicians who continue to order this treatment even though it’s considered a substandard practice for wound care?
