As clinicians, we’re proud of the expert care we provide patients. But we also know that just doing our job isn’t enough to advance our careers. Mastering good communication skills is essential for all clinicians at all career stages—especially with today’s flatter organizational structures and more participatory management styles. Knowing how to communicate in a professional manner can give you the edge you need for career advancement.
Opportunity rarely knocks any more. Instead it may present as a phone call, voice mail, e-mail, or text message. Be sure to use proper etiquette with all communication forms.
Speaking with managers
When dealing with your manager, use a solution-focused approach. Don’t be a complainer. Some communication experts point out that people complain about things they can do something about—not things they have no power over. For example, they don’t complain about their foot size because there’s nothing they can do about it. Yet people often complain about their jobs because they’re unwilling to take the risk of making a change.
We need to take charge of our lives. We can accept the fact—without complaining—that we’re making the choice to stay where we are. Or we can make a request or take action to achieve a desired outcome. Suppose you work on a clinical unit and disagree with the way your manager makes clinical assignments. You have several options:
Complain to coworkers and make the workplace miserable for others.
Speak with your manager and make suggestions for improvement.
Leave your job and go elsewhere if you can’t work with your manager to make things better.
If you decide to stay in your job, accept the fact that you’ve made that choice. Take responsibility for it and stop complaining.
Speaking on the phone with physicians
For clinicians who are not physicians, the key to effective communication with physicians is to remember you’re an important member of the healthcare team. An effective way to guide your communication with physicians and other colleagues is to use a tool such as SBAR (Situation, Background, Assessment, Recommendation). Say, for instance, you want to suggest the doctor order an anxiolytic for your patient. Here’s how you might do it using SBAR:
Situation: “Mrs. Smith is complaining of severe anxiety.” Background: “She is 1 day post-op from a lumbar laminectomy.” Assessment: “She is alert and oriented and her vital signs are stable. She has no numbness or tingling in her extremities.” Recommendation: “She said she takes lorazepam 2 mg orally at when she’s anxious. Would you like to order something for her?”
Before ending the conversation, repeat and clarify the medication order (if the doctor gives one).
Telephone
The sound of your voice and your manners are essential components of phone etiquette. Smile—the smile on your face comes through in your voice. Here are five more tips:
Get yourself organized before placing the call.
Minimize background noise.
Immediately identify yourself. Don’t assume the recipient will recognize your voice.
Concentrate on listening and avoid multitasking.
Schedule phone conversations to avoid playing phone tag.
Voice mail
Voice mail is an efficient way to communicate. Again, five tips:
Always be prepared to leave a message. Jot down your key message points before you call, to avoid stuttering and stammering.
Be concise and to the point.
State your name and the date, time, and purpose of your call.
Enunciate clearly and speak slowly.
State your name and phone number twice at the end of the message so the recipient doesn’t need to replay your message.
E-mail
In many business settings, e-mail has almost replaced letters and memos. In many cases, an e-mail is a recipient’s first impression of you, so follow these tips:
Make the subject line specific. This helps the reader prioritize the message and file it for easy retrieval.
Use a greeting and a close. It’s more polite and less impersonal.
Keep your message concise.
Keep your tone polite and businesslike.
Use your e-mail signature function, which provides several ways to contact you.
Text messages
This form of communication can be the most challenging and unpredictable. Some people send text messages routinely, while others may be unfamiliar with this method. You can’t go too far wrong if you take this advice:
Get to the point quickly. No one wants to read a long message on a mobile phone.
Don’t text during meetings. It’s rude to do so, and others can hear you clicking away or see the light from your screen.
Consider the recipient before using text abbreviations. Some people may not understand text lingo.
Consider the time when sending a text. Although you may be awake at 5 a.m., the sound of your incoming message might disturb a sleeping recipient.
Don’t expect an immediate response to your text. If the message is time sensitive, pick up the phone instead.
Improving the way we speak with managers and physicians can go a long way toward career advancement and professional satisfaction. Common courtesy is just as essential in e-mail, voice mail, and text messages as in face-to-face communication. When you follow the guidelines I’ve given, you’ll elevate your professional communications a few notches.

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

The number of people with diabetes who are meeting the ABC goals—hemoglobin A1C, blood pressure, and LDL cholesterol—has risen significantly in recent years, according to a study published by Diabetes Care. Patients meeting all three goals rose from about 2% in 1988 to about 19% in 2010.
Gains were made in each of the ABC goals, based on 2007 to 2010 data: 53% of patients met A1C goals, compared to 43% in 1988 to 1994 data; 51% met blood pressure goals, compared to 33%; and 56% met LDL goals, compared to 10%.
Younger people were less likely to meet A1C and cholesterol goals. Compared with non-
Hispanic whites, Mexican Americans were less likely to meet A1C and LDL goals and non-Hispanic blacks were less likely to meet blood pressure and LDL goals.
The researchers analyzed data from the National Health and Nutrition Examination Surveys from 1988–1994, 1999–2002, 2003–2006, and 2007–2010. Nearly 5,000 people age 20 or older participated.
Although progress had been made, the researchers conclude, “Despite significant improvement during the past decade, achieving the ABC goals remains suboptimal among adults with diabetes, particularly in some minority groups.”
Daily bathing with chlorhexidine-impregnated washcloths reduces infection risk
A study in The New England Journal of Medicine reports that daily bathing with chlorhexidine-impregnated washcloths reduces the risk of becoming infected with multidrug-resistant organisms and subsequent development of hospital-acquired bloodstream infections in intensive care unit patients.
“Effect of daily chlorhexidine bathing on hospital-acquired infection” included 7,727 patients in nine intensive care and bone marrow units in six hospitals. The units were randomly assigned to bathe patients with either no-rinse 2% chlorhexidine-impregnated washcloths or nonantimicrobial washcloths for 6 months; then, the units switched to the opposite product for 6 months.
The rate of infection with multidrug-resistant organisms was 23% lower in the chlorhexidine group and the rate of hospital-acquired bloodstream infection was 28% lower in the chlorhexidine group.
Patients tend not to wear custom-made footwear for preventing diabetic foot ulcers
Adherence to wearing prescription custom-made footwear was low among patients with diabetes, neuropathy, and a recently healed plantar foot ulcer, according to a study in Diabetes Care. The low adherence was particularly notable at home, where patients did the most walking.
Factors associated with higher adherence included lower body mass index, more severe foot deformity, and more appealing footwear.
Tedizolid works as well as linezolid in patients with acute bacterial skin infections
A JAMA study says that a 200-mg once-daily dose of oral tedizolid phosphate over 6 days was as effective as 600 mg of oral linezolid every 12 hours for 10 days in patients with acute bacterial skin and skin-structure infections, including cellulitis or erysipelas, major cutaneous abscesses, and wound infections.
A shorter course of tedizolid may be a “reasonable alternative” to linezolid for treating acute bacterial skin and skin-structure infections, the study concludes.
Water-based exercise improves ROM in patients with long-term arm lymphedema
A study of breast cancer survivors (median 10 years after surgery) with lymphedema found that a water-based exercise program improved shoulder range of motion (ROM).
The program consisted of at least twice-weekly water-based exercise for 8 weeks. At first, participants were supervised, but later they exercised independently. Although lymphedema status didn’t change, those who performed water-based exercise had an increase in ROM, showing improvement years after surgery.
Dehydrated amniotic membrane allograft possible option for treating chronic wounds
A dehydrated amniotic membrane allograft (EpiFix) was used to treat four patients whose wounds hadn’t closed after conservative and advanced measures and who had been referred for plastic procedures. A variety of wounds healed (located on the elbow, knee, hand, and ankle) after one to three applications of the amniotic material, which patients tolerated well. The wounds remained closed several months later.
Study casts doubt on MLD’s role in breast cancer–related lymphedema
A meta-analysis published in the World Journal of Surgical Oncology found the “current evidence” from randomized clinical trials “does not support” the use of manual lymphatic drainage (MLD) in preventing or treating lymphedema in patients with breast cancer.
The authors analyzed 10 randomized clinical trials with 566 patients.
CDC issues additional prevention steps for carbapenem-resistant Enterobacteriaceae
On Feb. 14, the Centers for Disease Control and Prevention (CDC) issued additional prevention steps for carbapenem-resistant Enterobacteriaceae (CRE). Increased reports of CRE prompted the action: Of the 37 unusual forms of CRE reported in the U.S., the last 15 have been reported since July 2012.
• When a CRE is identified in a patient with a history of an overnight stay in a healthcare facility (within the last 6 months) outside the U.S., send the isolate to a reference laboratory for confirmatory susceptibility testing and test to determine the carbapenem resistance mechanism.
• For patients admitted to healthcare facilities in the U.S. after recently being hospitalized (within the last 6 months) in countries outside the U.S., consider performing rectal screening cultures to detect CRE colonization, and place patients on contact precautions while awaiting the results.
Examples of Enterobacteriaceae include Klebsiella species and Escherichia coli. CRE are Enterobacteriaceae with high levels of resistance to antibiotics, including carbapenems. CRE infections most commonly occur among patients who are receiving antibiotics and significant medical treatment for other conditions.
Clinical practice guidelines help ensure we are applying the latest knowledge and expertise when we’re caring for patients. Here are a few recent guidelines that you may find useful.
Measurement of ankle-brachial index
An American Heart Association scientific statement, “Measurement and interpretation of the ankle-brachial index (ABI),” published in Circulation, outlines the use of ABI, terminology, how to calculate the value, training, standards, and suggestions for future research.
Recommendations for obtaining an ABI measurement include:
• Use the Doppler method to determine the systolic blood pressure in each arm and each ankle.
• Use the appropriate cuff size, with a width of at least 40% of the limb circumference.
• Place the ankle cuff just above the malleoli with the straight wrapping method.
• Cover open lesions with the potential for contamination with an impermeable dressing.
• Avoid using a cuff over a distal bypass.
The article also recommends measurement and interpretation of ABI be part of the standard curriculum for nursing and medical students. For more information about ABI, read “Bedside ankle-brachial index testing: Time-saving tips” in this issue of Wound Care Advisor.
Childhood obesity continues to be a significant problem in the United States, requiring innovative approaches for prevention and management. Those who are obese run the risk of poorer wound healing.
“Approaches to the prevention and management of childhood obesity: The role of social networks and the use of social media and related electronic technologies: A scientific statement from the American Heart Association,” published in Circulation, evaluates the role of social networks and social media in relation to childhood obesity and presents five steps for using social networks: 1 Define the goal of the intervention. 2 Identify the social network. 3 Develop and pilot test the intervention. 4 Implement the intervention. 5 Spread the intervention.
The guidelines conclude that social media holds promise as a tool, but more research is needed.

Patients have a right to make their own decisions, but what happens when a decision is so painful for staff that it affects morale? Arthur Caplan, PhD, Division of Medical Ethics at the NYU Langone Medical Center in New York, discusses such a case: “Patients have the right to choose death from bedsores.”
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.

Every year, 1.9% of patients with diabetes develop foot ulcers. Of those, 15% to 20% undergo an amputation within 5 years of ulcer onset. During their lifetimes, an estimated 25% of diabetic patients develop a foot ulcer. This article discusses use of hyperbaric oxygen therapy (HBOT) in treating diabetic foot ulcers, presenting several case studies.
HBOT involves intermittent administration of 100% oxygen inhaled at a pressure greater than sea level. It may be given in a:
• multi-place chamber (used to treat multiple patients at the same time), compressed to depth by air as the patient breathes 100% oxygen through a face mask or hood (more…)
Renee asks her mentor, Susan, a question. Susan puts her hand near Renee’s face, gesturing for her to “Stop,” and says in a loud voice, “I told you the answer to that this morning. Why are you bothering me again?”
You’re working your shift with Amy, who’s in charge of the unit. She refuses to have a meaningful conversation with you, and ignores you or sighs impatiently when you try to share patient information with her.
These examples reflect lateral (horizontal) violence or abuse in the workplace, defined as violence or abuse occurring between workers. It includes both overt and covert acts of verbal and nonverbal aggression.
Chances are you’ve experienced or witnessed disruptive or inappropriate behavior by a peer or colleague. Intimidation, bullying, insults, humiliation, gossip, constant criticism, and angry outbursts are a few examples. More subtle examples include favoritism, unfair work assignments, inappropriate or unfair evaluations, sarcasm, snide comments, withholding information, holding a grudge, and belittling gestures.
Lateral violence in any form feels bad. It creates fear—and fear causes you to shrink and hold back from being your best. You can’t be productive in a fearful environment. Instead, you may feel violated, anxious, stressed, disrespected, and angry. A response of silence or ignoring the offender is common, but not ideal. Here are some better strategies.
Acknowledge your feelings
Admit to yourself that you’re hurting and something is wrong. Many victims dismiss or minimize the event, or even blame themselves. Resist that temptation. If it feels bad, it is bad. And if you allow the behavior, that person is sure to repeat it—not because she’s a bad person, but because she doesn’t realize her behavior is wrong. If you respond by acting surprised and assuming she doesn’t know what she’s doing and has no idea how her actions affect you, it will be easier to respond professionally and quickly.
If abuse or violence of any form is tolerated, it will continue. And the negative workplace culture will significantly affect the health and well-being of both staff and patients.
Respond appropriately
Here are the four keys to responding appropriately to lateral violence in the workplace—or anywhere else, for that matter.
Manage your emotions
Take a deep breath and pause. Don’t react right away. Self-awareness is crucial to managing your emotions and your responses. Take a time-out if you’ve become emotional. Use calming techniques, such as deep breathing, guided imagery, humor, or prayer. If you try to deal with the perpetrator while upset, you’re more likely to behave unprofessionally. Restrain yourself until you feel able to assert yourself in a professional manner.
Use empathy
Try to find out where the person’s coming from to help understand what’s going on with her that might have triggered her behavior. For example, a person may engage in negative behavior because she’s going through a divorce. (See It’s not about you by clicking the PDF icon above.)
Keep in mind that bad behavior reflects poor self-esteem and serves as a wall to keep people out. It’s also learned behavior. Someone who behaves badly has learned this behavior brings some kind of reward; otherwise, she wouldn’t do it. Perhaps the reward is attention or power. Whatever it is, she gains something from the behavior at others’ expense. Most likely, she’s unaware of this dynamic.
By using empathy, you not only learn more about the offender; that person learns more about herself. Show an interest in why she behaved that way by asking questions; for instance: “I’ve noticed you’ve been more impatient lately. Are you okay? Is there something going on I should know about?” When you’ve gained a clearer understanding of the person, you can set clear expectations and boundaries.
Assert your boundaries
Asserting your boundaries tells others what behaviors are unacceptable. When you assert your boundaries, you honor yourself. When something doesn’t feel right, tell the person directly that her behavior is inappropriate and ask her to stop it. If you say nothing, your silence implies the behavior is acceptable.
Tell the person directly that her behavior is inappropriate. Keep it simple and clear. Use such language as “This doesn’t work for me.” That way, you’re accepting responsibility for your feelings and you’re not making her wrong.
Asserting a boundary might sound like this: “Please lower your voice.” But be careful of the tone you use when making the request. You might ask, “Did you realize you were yelling?” She might not be aware of how angry or loud she is at that moment.
Make direct requests
Tell the person directly how you’d like to be treated or how you want the two of you to work together. Identify what you want instead of what you’re getting—and then ask for it. Don’t assume she knows how to treat you. Determine what your goals are and what you need from her to accomplish what’s expected. If you can, try to establish a mutual goal for you both to work on, such as a more productive relationship so there’s less tension. Clearly communicating your requests informs others of the behavior you expect.
A case of respect
You might not want to befriend people at work, and you don’t have to like them. But each of us deserves to be treated with respect. To get respect, you must give it. If it’s not reciprocated, ask for it. Treat everyone with respect.
If you experience lateral hostility or violence on the job, deal with it directly and immediately. If it happens again, deal with it directly again and report it to your supervisor.
No matter how professional and respectful you are or how assertively you express your boundaries and needs, if your work environment remains abusive and leadership doesn’t address it or do enough to change it, you may need to leave your job. Stop wasting time and energy trying to fix a problem no one else wants to fix. Life is too short, and you deserve better.

Staphylococcus aureus is one of the most feared human pathogens, causing a wide range of infections. Most wound care professionals can expect to frequently encounter patients with S. aureus infections. Soft-tissue infections caused by S. aureus include impetigo, cellulitis, and cutaneous abscesses, as well as such life-threatening processes as necrotizing fasciitis and pyomyositis (a hematogenous intramuscular abscess). Serious non-soft-tissue infections include septic arthritis, osteomyelitis, pneumonia, endocarditis, and sepsis.
Why is S. aureus such a nasty bug?
S. aureus produces various cellular and extracellular factors involved in the pathogenesis of infection. S. aureus protein A, an important surface protein, helps the organism resist phagocytosis. Also, S. aureus produces several cytotoxins and enzymes that contribute to infection spread and severity. In addition, some strains produce toxins (including toxic shock syndrome toxin-1) that function as superantigens—molecules that nonspecifically trigger release of large amounts of cytokines, leading to a sepsislike condition. Taken together, such factors combine to make S. aureus a dangerous pathogen.
MRSA emergence
When penicillin was introduced in the 1940s, virtually all S. aureus isolates were sensitive to that drug. But soon thereafter, S. aureus strains that produced a β-lactamase enzyme capable of inactivating penicillin became widespread. During the 1950s, outbreaks of penicillin-resistant S. aureus occurred in many U.S. hospitals. Introduction of penicillinase-resistant antibiotics, such as methicillin and oxacillin, temporarily restored the ability to treat all strains of this pathogen using penicillin antibiotics. The first strain of methicillin-resistant S. aureus (MRSA) was described in 1961 shortly after introduction of penicillinase-resistant antibiotics.
The mechanism of methicillin resistance involves a mutation in one of the bacterial cell-wall proteins to which penicillins must bind to kill the bacterium. This mutation renders the organism resistant to all penicillins and penems and almost all cephalosporins.
MRSA incidence has increased steadily to the point where it currently constitutes up to 60% of S. aureus isolates in many U.S. hospitals. These organisms commonly carry genetic material that makes them resistant to various non-β lactam antibiotics as well, leading some to suggest that the term MRSA should stand for multiply resistant S. aureus. S. aureus has continued to mutate in the face of persistent antibiotic pressure. Vancomycin-intermediate S. aureus (VISA) was described in 1997; vancomycin-resistant S. aureus (VRSA), in 2003. Fortunately, these two strains remain rare and haven’t become established pathogens. (See Strains of antibiotic-resistantS. aureus by clicking the PDF icon above.)
Healthcare- versus community-acquired MRSA
Although MRSA initially arose and spread within healthcare settings (chiefly acute-care hospitals), a community-based variant was described in 1998. Called community-
acquired MRSA (CA-MRSA), this variant differs from healthcare-associated MRSA (HCA-MRSA) in more ways than the acquisition site. CA-MRSA occurs predominately in otherwise healthy children and young adults.
It most commonly presents as recurrent cutaneous abscesses, although life-threatening infections (such as necrotizing fasciitis and pneumonia) also have occurred. The propensity to cause cutaneous abscesses isn’t fully understood but may relate partly to production of the Panton-Valentine toxin by many CA-MRSA isolates.
In contrast, HCA-MRSA afflicts mainly older patients, particularly those with chronic illnesses, including chronic wounds. It typically causes wound infections, urinary tract infections, pneumonia, and bacteremia.
Besides these epidemiologic and clinical differences, many CA-MRSA isolates derive from a single clone, known as clone USA 300, whereas HCA-MRSA is composed of multiple non-USA 300 clones. Finally, many CA-MRSA isolates are sensitive to non-β
lactam antibiotics, whereas most HCA-MRSA isolates resist multiple antibiotics. More recently, the distinction between CA-MRSA and HCA-MRSA has been blurred as evidence emerges that CA-MRSA now is being transmitted in healthcare settings as well as in the community.
S. aureus carrier state
Staphylococci are frequent colonizers of humans. Common colonization sites include the skin, anterior nares, axillae, and inguinal regions. Individuals can be colonized continuously or transiently, with nasal carriage rates varying from 20% to 40%. Most S. aureus infections result from the strain carried by the infected patient.
Three patterns of S. aureus carriage exist in humans:
• 20% of individuals are continuously colonized.
• 30% of individuals are intermittently colonized.
• 50% of individuals are never colonized.
The highest carriage rates occur in patients receiving frequent injections (such as insulin-dependent diabetics, hemodialysis patients, and I.V. drug users) and those with chronic skin conditions (for instance, psoriasis or eczema). In the general population, MRSA carriage rates have increased to 1% or 2%, with clinical consequences hinging on the colonizing strain (CA-MRSA versus HCA-MRSA) and host characteristics. The most consistent carriage site is the anterior nares, but many other sites may carry this pathogen, including the axillae, inguinal regions, and perirectal area.
MRSA treatment
Therapy for MRSA infection depends on the infection location and antibiotic sensitivity of the infecting strain.
• Cutaneous abscesses are treated by incision and drainage; antibiotics play a secondary role to adequate drainage.
• Therapy for necrotizing fasciitis caused by MRSA involves aggressive debridement with removal of all necrotic tissue, plus adequate antibiotic therapy. Typically, patients require serial debridement followed by subsequent careful wound care, often with eventual skin grafting.
• Pyomyositis treatment entails drainage of the muscle abscess (which sometimes can be done with percutaneous tube placement instead of open drainage), plus appropriate antibiotic therapy.
Vancomycin has been the mainstay of I.V. therapy for MRSA for decades, but some clinicians are concerned that its effectiveness may be declining due to slowly increasing minimum inhibitory concentrations (the minimum concentration of an
antibiotic needed to inhibit pathogen growth). Other parenteral options have emerged in the last few years. (See I.V. drugs used to treat MRSA by clicking the PDF icon above.) Several oral antibiotics also are available for MRSA treatment. (See Oral agents used to treat MRSA by clicking the PDF icon above.)
Knowing the antibiotic sensitivity pattern of the infecting MRSA strain is crucial to ensuring that the patient receives an appropriate antibiotic. Treatment duration for soft-
tissue infections usually ranges from 7 to 14 days, but bacteremia and bone or joint infections call for more prolonged therapy.
Efforts to eradicate MRSA carriage
Because the carrier state increases the risk of subsequent S. aureus infection, efforts have been made to eradicate carriage. Unfortunately, this has proven to be difficult. A commonly used regimen involves 5 days of twice-daily mupirocin nasal ointment with either chlorhexidine gluconate showers or immersion up to the neck in a dilute bleach solution. However, success in eliminating carriage is limited, although the bleach bath seems to improve eradication rates better than other modalities.
Controlling MRSA in hospitals
How best to control MRSA spread within hospitals is controversial. Some experts advocate an aggressive, “search and destroy” approach involving screening all patients for nasal carriage on admission and initiating contact precautions with subsequent decolonization efforts. Others focus on improving the overall level of hand hygiene and other general infection-control measures, arguing that nasal screening misses at least 20% of MRSA-colonized patients and thus gives an unwarranted sense of security.
Many hospitals use a mixed approach, screening patients suspected to be at high risk for MRSA carriage (such as those admitted from extended-care facilities or to the intensive care unit), while simultaneously trying to improve hand hygiene and general infection-control measures. Recent data suggest MRSA colonization and infection rates have stopped increasing and are beginning to decline.
MRSA is one of the most problematic pathogens encountered on a regular basis, and among the most dangerous pathogens we face. While some MRSA infections are relatively mild, many are serious or life-threatening. Severe soft-tissue infections, such as necrotizing fasciitis and pyomyositis, require surgical debridement or drainage, appropriate antibiotic therapy, and assistance from a wound-care professional to achieve optimal outcomes. n

New wound-swabbing technique detects more bacteria
The new Essen Rotary swabbing technique takes a few seconds longer to perform than traditional techniques, but improves bacterial count accuracy in patients with chronic leg ulcers, according to a study published by Wounds International.
“Evaluation of the Essen Rotary as a new technique for bacterial swabs: Results of a prospective controlled clinical investigation in 50 patients with chronic leg ulcers” reports that Essen Rotary detected significantly more bacteria compared to standard techniques and was the only one to identify five patients with methicillin-resistant Staphylococcus aureus (MRSA), compared to three detected by other techniques.
The Essen Rotary technique samples a larger surface area of the wound, which is beneficial for detecting MRSA.
“The Essen Rotary may become the new gold standard in routinely taken bacteriological swabs especially for MRSA screenings in patients with chronic leg ulcers,” the study authors write.
Reducing HbA1c by less than 1% cuts cardiovascular risk by 45% in patients with type 2 diabetes
A study presented at the American Diabetes Association 72nd Scientific Sessions found lowering HbA1c an average of 0.8% (from a mean of 7.8% to 7.0%, the treatment target) reduced the risk of cardiovascular death by 45% in patients with type
2 diabetes.
The absolute risk of mortality from a cardiovascular event was 9.9 events per 1,000 person-years in patients with decreasing HbA1c compared to 17.8 events in patients with stable or increasing HbA1c.
“HbA1c reduction and risk of cardiovascular diseases in type 2 diabetes: An observational study from the Swedish NDR” examined data from 18,035 patients in the Swedish National Diabetes Register.
CMS revises hospital, nursing home comparison websites
The Centers for Medicare & Medicaid Services (CMS) has enhanced two websites designed to help the public make informed choices about their health care. Hospital Compare and Nursing Home Compare now have better navigation and new comparison tools. The two sites include data on quality measures, such as frequency of hospital-acquired infections, and allow the user to compare hospitals on these measures.
Improvements include easy-to-use maps for locating hospitals, a new search function that enables the user to input the name of a hospital, and glossaries that are easier to understand. It’s now also possible to access the data on the sites through mobile applications.
CMS maintains the websites, which are helpful for anyone who wants to compare facilities, not just patients on Medicare or Medicaid.

IOM releases report on accelerating new drug and diagnostics development
The Institute of Medicine (IOM) released “Accelerating the development of new drugs and diagnostics: Maximizing the impact of the Cures Acceleration Network—Workshop Summary.” The report is a summary of a forum that brought together members of federal government agencies, the private sector, academia, and advocacy groups to explore options and opportunities in the implementation of Cures Acceleration Network (CAN). The newly developed CAN has the potential to stimulate widespread changes in the National Institutes of Health and drug development in general.
Focus on individualized care—not just reducing swelling—in lymphedema patients
As a result of two extensive literature reviews, a researcher at the University of Missouri found that emphasizing quality of life—not just reducing swelling—is important for patients with lymphedema. Many providers and insurance companies base treatment on the degree of edema, but the volume of fluid doesn’t always correspond with the patients’ discomfort. Instead, an individualized plan of care should be developed.
The researchers found that Complete Decongestive Therapy (CDT), a comprehensive approach for treating lymphedema that includes skin and nail care, exercise, manual lymphatic drainage, and compression, may be the best form of specialized lymphedema management. For more information about CDT, watch for the November/December issue of Wound Care Advisor.
Plague case in Oregon draws national attention
An article about a case of the plague in Oregon has appeared on Huffington Post. A welder contracted the disease as a result of unsuccessfully removing a mouse from a stray cat’s mouth. Part of his hands have, in the words of the article, “darkened to the color of charcoal.” Later tests confirmed the cat had the plague.
Plague cases are rare in the United States. According to the Centers for Disease Control and Prevention, an average of 7 human cases are reported each year, with a range of 1 to 17 cases. Antibiotics have significantly reduced morality. About half of cases occur in people ages 12 to 45.
Use of negative pressure wound therapy with skin grafts
“Optimal use of negative pressure wound therapy for skin grafts,” published by International Wound Journal, reviews expert opinion and scientific evidence related to the use of negative pressure wound therapy with reticulated open-cell foam for securing split-thickness skin grafts.
The article covers wound preparation, treatment criteria and goals, economic value, and case studies. The authors conclude that the therapy has many benefits, but note that future studies are needed “to better measure the expanding treatment goals associated with graft care, including increased patient satisfaction, increased patience compliance and improved clinical outcomes.”
Mechanism for halting healing of venous ulcers identified
Researchers have identified that aberrantly expressed microRNAs inhibit healing of chronic venous ulcers, according to a study in The Journal of Biological Chemistry.
Six microRNAs were plentiful in 10 patients with chronic venous ulcers. The microRNAs target genes important in healing the ulcers. In an article about the study, one of the researchers said, “The more we know about the molecular mechanisms that contribute to [the development of venous ulcers], the more we can rationally develop both diagnostic tools and new therapies.”
Hemodialysis-related foot ulcers not limited to patients with diabetes
Both patients with diabetes and those without are at risk for hemodialysis-related foot ulcers, according to a study published by International Wound Journal.
Researchers assessed 57 patients for ulcer risk factors (peripheral neuropathy, peripheral arterial disease, and foot pathology, such as claw toes, hallux valgus, prominent metatarsal heads, corns, callosities, and nail pathologies) at baseline, and noted mortality 3 years later.
In all, 79% of patients had foot pathology at baseline, and 18% of patients without diabetes had peripheral neuropathy. Peripheral arterial disease was present in 45% of diabetic and 30% of nondiabetic patients. Nearly half (49%) of patients had two or more risk factors. Only 12% of patients had no risk factors. The presence of peripheral arterial disease and peripheral neuropathy increased risk of mortality.
The authors of “Prevalence of risk factors for foot ulceration in a general haemodialysis population” state that the high prevalence of risk factors in nondiabetic patients indicates that they are at risk for developing foot ulcers.
Study identifies risk factors for mortality from MRSA bacteremia
A study in Emerging Infectious Diseases found that older age, living in a nursing home, severe bacteremia, and organ impairment increase the risk of death from methicillin-resistant Staphylococcus aureus (MRSA) bacteremia.
Consultation with a specialist in infectious disease lowers the risk of death, and MRSA strain types weren’t associated with mortality.
“Predicting risk for death from MRSA bacteremia” studied 699 incidents of blood infection from 603 patients who had MRSA bacteremia.

Moisture-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.
Causes
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.
Categorizing IAD
IAD is categorized as mild, moderate, or severe. (See Picturing IAD by clicking the PDF icon above.)
Screening for IAD
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:
IAD can occur wherever urine or stool contacts the skin. In contrast, pressure ulcers arise over bony prominences in the absence of moisture.
With IAD, affected skin is red or bright red. With a pressure ulcer, skin may take on a bluish purple, red, yellow, or black discoloration.
The skin-damage pattern in IAD usually is diffuse. With a pressure ulcer, edges are well defined.
The depth of IAD-related skin damage usually is partial-thickness without necrotic tissue. With a pressure ulcer, skin damage depth may vary.
Preventing IAD
The three essentials of IAD prevention are to cleanse, moisturize, and protect.
Cleanse the skin with a mild soap that’s balanced to skin pH and contains surfactants that lift stool and urine from the skin. Clean the skin routinely and at the time of soiling. Use warm (not hot) water, and avoid excess force and friction to avoid further skin damage.
Moisturize the skin daily and as needed. Moisturizers may be applied alone or
incorporated into a cleanser. Typically, they contain an emollient such as lanolin to replace lost lipids in the stratum corneum.
To protect the skin, apply a moisture-barrier cream or spray if the patent has significant urinary or fecal incontinence (or both). The barrier may be zinc-based, petrolatum-based, dimethicone-based, an acrylic polymer, or another type. Consider using an algorithm developed by wound and skin care specialists that’s customized for skin care products your facility uses. (See Skin care algorithm by clicking the PDF icon above.)
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.
Managing IAD
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.
Referrals and education
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.
