Guidelines for managing prosthetic joint infections released

The Infectious Diseases Society of America has released guidelines for diagnosing and managing prosthetic joint infections.
“Diagnosis and management of prosthetic joint infection: Clinical practice guidelines by the Infectious Diseases Society of America,” published in Clinical Infectious Diseases, notes that of the 1 million people each year who have their hips or knees replaced, as many as 20,000 will get an infection in the new joint.
The guidelines describe the best methods for diagnosing these infections, which are not easy to identify. Specifically, infection should be suspected in a patient who has any of the following: persistent wound drainage in the skin over the joint replacement, sudden onset of a painful prosthesis, or ongoing pain after the prosthesis has been implanted, especially if there had been no pain for several years or if there is a history of prior wound healing problems or infections.
Guidelines for treating infections are included and note that 4 to 6 weeks of I.V. or highly bioavailable oral antibiotic therapy is almost always necessary to treat prosthetic joint infections.

A decade of TIME

The TIME acronym (tissue, infection/inflammation, moisture balance, and edge of wound) was first developed more than 10 years ago to provide a framework for a structured approach to wound bed preparation and a basis for optimizing the management of open chronic wounds healing by secondary intention. To mark the event, the International Wound Journal has published “Extending the TIME concept: What have we learned in the past 10 years?”
The review points out four key developments:
• recognition of the importance of biofilms (and the need for a simple diagnostic)
• use of negative-pressure wound therapy
• evolution of topical antiseptic therapy as dressings and for wound lavage (notably, silver and polyhexamethylene biguanide)
• expanded insight into the role of molecular biological processes in chronic wounds (with emerging diagnostics).
The authors conclude, “The TIME principle remains relevant 10 years on, with continuing important developments that incorporate new evidence for wound care.”

Bed alarms fail to reduce patient falls

A study in Annals of Internal Medicine found that the use of bed alarms had no statistical or clinical effect on falls in an urban community hospital.
The 18-month trial included 16 nursing units and 27,672 inpatients. There was no difference in fall rates per 1,000 patient-days, the number of patients who fell, or the number of patients physically restrained on units using bed alarms, compared with control units.
Authors of “Effects of an intervention to increase bed alarm use to prevent falls in hospitalized patients: A cluster randomized trial” speculate the lack of response may be related to “alarm fatigue.”

Drug for HIV might help in Staph infections

A study in Nature reports that the drug maraviroc, used to treat HIV, might be useful for treating Staphylococcus aureus infections.
“CCR5 is a receptor for Staphylococcus aureus leukotoxin ED” found that the CCR5 receptor, which dots the surface of immune T cells, macrophages, and dendritic cells, is critical to the ability of certain strains of Staph to specifically target and kill cells with CCR5, which orchestrate an immune response against the bacteria. One of the toxins the bacterium releases, called LukED, latches on to CCR5 and subsequently punches holes through the membrane of immune cells, causing them to rapidly die.
When researchers treated cells with CCR5 with maraviroc and exposed the cells to the Staph toxin, they found maraviroc blocked toxic effects.

Dog able to sniff out C. difficile

A 2-year-old beagle trained to identify the smell of Clostridium difficile was 100% successful in identifying the bacteria in stool samples, and correctly identified 25 of 30 cases of patients with C. difficile, according to a study in BMJ.
“Using a dog’s superior olfactory sensitivity to identify Clostridium difficile in stools and patients: Proof of principle study” discusses how the dog was trained to detect C. difficile and concludes that although more research is needed, dogs have the potential for screening for C. difficile infection.

After-hours access to providers reduces ED use

Patients who have access to their primary healthcare providers after hours use emergency departments (EDs) less frequently, according to a study in Health Affairs.
“After-hours access to primary care practices linked with lower emergency department use and less unmet medical need” found that 30.4% of patients with after-hours access to their primary care providers reported ED use, compared with 37.7% of those without this access. In addition, those with after-hours access had lower rates of unmet needs (6.1% compared to 12.7%).
The findings come from the 2010 Health Tracking Household Survey of the Center for Studying Health System Change. The total sample included 9,577 respondents.

Neuropathic pain in patients with DPN might contribute to risk of falling

The presence of neuropathic pain in patients with diabetic peripheral neuropathy (DPN) contributes to gait variability, which could in turn contribute to the risk of falling, according to “Increased gait variability in diabetes mellitus patients with neuropathic pain.”
The study, published in the Journal of Diabetes and Its Complications, compared patients with at least moderate neuropathic pain with those who had no pain. Researchers used a portable device to measure gait parameters, such as step length and step velocity.

Amputation rates decrease significantly in patients with PAD

“Temporal trends and geographic variation of lower-extremity amputation in patients with peripheral artery disease (PAD): Results from U.S. Medicare 2000–2008” found that amputation rates have decreased significantly, but that significant patient and geographic variations remain.
The study, published in the Journal of the American College of Cardiology, found that among 2,730,742 older patients with identified PAD, the overall rate of lower extremity amputation decreased from 7,258 per 100,000 patients to 5,790 per 100,000. Predictors of lower-extremity amputation included male sex, black race, diabetes mellitus, and renal disease.

NPUAP releases new position statement on exposed cartilage as Stage IV ulcer

The National Pressure Ulcer Advisory Panel (NPUAP) has released a new position statement, “Pressure ulcers with exposed cartilage are Stage IV pressure ulcers,” which states that pressure ulcers with exposed cartilage should be classified as Stage IV.
NPUAP notes that although the presence of “visible or palpable cartilage at the base of a pressure ulcer” wasn’t included in Stage IV terminology, cartilage “serves the same anatomical function as bone,” so it fits into the current Stage IV definition, “Full thickness tissue loss with exposed bone, tendon or muscle. Slough or eschar may be present on some parts of the wound bed. Often including undermining and tunneling.”

Medicare expenditures for diabetic foot care varies significantly by region

Medicare spending on patients with diabetes who have foot ulcers and lower extremity amputations varies significantly by region, according to a study in Journal of Diabetes and Its Complications, but more spending doesn’t significantly reduce 1-year mortality.
“Geographic variation in Medicare spending and mortality for diabetic patients with foot ulcers and amputations” examined data from 682,887 patients with foot ulcers and 151,752 patients with lower extremity amputations.
Macrovascular complications in patients with foot ulcers were associated with higher spending, and these complications in patients with amputations were more common in regions with higher mortality rates.
Rates of hospital admission were associated with higher spending and increased mortality rates for patients with foot ulcers and amputations.
“Geographic variation in Medicare spending and mortality rates for diabetic patients with foot ulcers and amputations is associated with regional differences in the utilization of inpatient services and the prevalence of macrovascular complications,” the study concludes.

Patients who develop pressure ulcers in hospital more likely to die

Medicare patients who develop pressure ulcers in the hospital are more likely to die during the hospital stay, have longer lengths of stay, and to be readmitted within 30 days after discharge, according to a study of 51,842 patients in the Journal of the American Geriatrics Society.
“Hospital-acquired pressure ulcers: results from the National Medicare Patient Safety Monitoring System Study” found that 4.5% of patients developed at least one new pressure ulcer during their hospitalization. Length of stay averaged 4.8 days for patients who didn’t develop a pressure ulcer, compared to 11.2 days for those with a new pressure ulcer.

Patients with diabetic foot ulcers may have higher risk of death

Patients with diabetes who have foot ulcers have a higher risk of cardiovascular disease and mortality, according to a meta-analysis in Diabetologia.
“The association of ulceration of the foot with cardiovascular and all-cause mortality in patients with diabetes: a meta-analysis” notes that the more frequent occurrence of cardiovascular disease only partly explains the increased mortality rate. Other explanations may include the more advanced stage of diabetes associated with those who had foot ulcers.
A Drugs.com article about the study reported that “analysis of data from more than 17,000 diabetes patients in eight studies found that the more than 3,000 patients with a history of foot ulcers had an extra 58 deaths per 1,000 people each year than those without foot ulcers.”
The study authors emphasize the importance of screening patients with diabetes for foot ulcers so intervention can begin early, as well as lowering cardiovascular risk factors.

Nurse’s innovation for ostomy patients could improve quality of life

An oncology nurse in Australia has developed StomaLife, an alternative to ostomy bags.
StomaLife is a ceramic appliance that eliminates the need for an ostomy bag. According to the StomaLife website, the appliance uses a magnetic implant technology that provides a “pushing force” from within the body outward in order to keep the site intact, while a second part is placed on the stoma site. A cotton gauze pad is used between the skin and the appliance to keep the site separated and to provide air circulation to the surrounding skin.
“The benefits of StomaLife to ostomy patients are continence all day, reduced skin irritation and infection, odour and sound control, leak prevention, waste material flow control and on-demand gas release,” says Saied Sabeti.
StomaLife still needs to be tested and is not yet being produced.

New laser-activated bio-adhesive polymer aims to replace sutures

The Journal of Visualized Experiments, a peer-reviewed video journal, has published “A chitosan based, laser activated thin film surgical adhesive, ‘SurgiLux’: preparation and demonstration.”
SurgiLux is a laser-activated, bio-adhesive polymer that is chitosan-based. Chitosan is a polymer derived from chitin, which is found in fungal cell walls or in exoskeletons of crustaceans and insects. This molecular component allows SurgiLux to form low-energy bonds between the polymer and the desired tissue when it absorbs light.
The technology may be able to replace traditional sutures in the clinical setting. SurgiLux polymer can achieve a uniform seal when activated by a laser and has antimicrobial properties, which help prevent a wound from becoming infected. It also maintains a barrier between the tissue and its surroundings.
SurgiLux has been tested both in vitro and in vivo on a variety of tissues, including nerve, intestine, dura mater, and cornea.

Palliative care raises patient satisfaction and reduces costs

Kaiser Permanente’s home-based palliative care program increased patient satisfaction and decreased emergency department visits, inpatient admissions, and costs, according to an innovation profile in the Agency for Healthcare Research and Quality’s Innovations Exchange.
“In-home palliative care allows more patients to die at home, leading to higher satisfaction and lower acute care utilization and costs” notes that the program uses an interdisciplinary team of providers to manage symptoms and pain, provide emotional and spiritual support, and educate patients and family members on an ongoing basis about changes in the patient’s condition.
Other components of the program include a 24-hour nurse call center, biweekly team meetings, and bereavement services to the family after the patient dies.

More research needed to determine efficacy of maggot debridement therapy

“The efficacy of maggot debridement therapy (MDT)—a review of comparative clinical trials” concludes that “poor quality of the data used for evaluating the efficacy of MDT highlights the need for more and better designed investigations.”
The authors of the article in International Wound Journal reviewed three randomized clinical trials and five nonrandomized clinical trials evaluating the efficacy of sterile Lucilia sericata applied on ulcers.
The studies found that MDT was “significantly more effective than hydrogel or a mixture of conventional therapy modalities, including hydrocolloid, hydrogel and saline moistened gauze,” but the designs of the study were “suboptimal.”

Use tool to select correct antimicrobial dressing

“Ensuring that the correct antimicrobial dressing is selected,” in Wounds International, emphasizes that dressing selection should be based on assessment of the microbial burden in the wound, the wound type, and the location and condition of the wound.
The article includes a checklist that may be helpful for deciding on the level of bacterial burden in a wound. The checklist is used to determine four levels of risk—colonized: at risk; localized infection; spreading infection; and systemic infection. Each level has a corresponding definition.
A table of antimicrobial dressings reviews the antimicrobial agent and dressing form, and the article ends with a case study.

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

The four typical settings for NF are:

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

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

Overview

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

Pathophysiology

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

Disease progression

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

Assessment

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

Diagnosis

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

Treatment

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

Supportive care and follow-up treatment

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

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

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

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

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

Special needs of home-care patients

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

Role of the WCC

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

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

Challenges of home care

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

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

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

Develop a checklist

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

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

Hours and safety concerns

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

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

Reimbursement

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

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

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

A worthwhile option

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