  1. Clinical Practice Guideline(CPG) for Pressure Ulcers For Practitioners

  2. What is a Pressure Ulcer? • Definition: A pressure ulcer is a localized injury to the skin or underlying tissue, usually over a bony prominence, that is a result of pressure or of pressure combined with shear or friction. • Reported prevalence rates have ranged from 2.3 percent to 28 percent and reported incidence rates from 2.2 percent to 23.9 percent

  3. What is a Pressure Ulcer? • 95% of pressure ulcers develop on the lower body (about 65% in the pelvic area and 30% in the lower extremities) • 2-6 times greater mortality risk • Effective pressure ulcer treatment best achieved through interdisciplinary team approach

  4. Guidelines for Pressure Ulcers • Recognition • Diagnosis • Prevention and Treatment • Monitoring

  5. Recognition Steps • Examine the patient’s skin thoroughly to identify existing pressure ulcers • Identify risk factors for developing pressure ulcers • Review records/resident interview to identify previous history of pressure ulcers

  6. Distinguishing Features of Common Types of Ulcers

  7. F314 Surveyor Guidance: Risk Factors for Developing Pressure Ulcers • According to the surveyor guidance accompanying F314, the risk factors that increase a patient’s susceptibility to developing pressure ulcers, or that may impair the healing of an existing pressure ulcer, include but are not limited to the following: • Comorbid conditions (e.g., diabetes mellitus, end-stage renal disease, thyroid disease) • Drugs that may affect ulcer healing (e.g., steroids) • Exposure of skin to urinary or fecal incontinence • History of a healed Stage III or IV pressure ulcer • Impaired diffuse or localized blood flow (e.g., generalizedatherosclerosis, lower-extremity arterial insufficiency)

  8. F314 Surveyor Guidance: Risk Factors for Developing Pressure Ulcers • Impaired or decreased mobility and functional ability • Increase in friction or shear • Moderate to severe cognitive impairment • Resident refusal of some aspects of care and treatment • Undernutrition, malnutrition, and hydration deficits (Adapted from CMS, 2007)

  9. Assessment • Assess the patient’s overall physical and psychosocial health and characterize the pressure ulcer • Identify factors that can affect ulcer treatment and healing • Identify priorities in managing the ulcer and the patient

  10. Assessment A pressure ulcer should be assessed in the context of the patient’s overall clinical, functional, and cognitive status. • Assess the status of each of the patient’s current medical conditions. • Assess the patient’s nutritional status, including dietary and fluid intake • Assess for the presence of medical conditions that may interfere with independent feeding or decrease overall oral intake

  11. Assessment • In patients with lower-extremity ulcers, assess for the presence of coolness, delayed capillary refill, dusky discoloration, or pedal pulses. The ankle-brachial index, determined by Doppler arterial studies, may be helpful in determining whether a lower-extremity ulcer is caused by vascular insufficiency or by pressure. • Assess the patient’s bed and chair mobility and ability to sense and react to pain and discomfort.

  12. Other Factors That Should Be Assessed in a Patient With a Pressure Ulcer • Comorbid conditions (e.g., anemia, congestive heart failure, diabetes, edema*, immune deficiency, malignancies, peripheral vascular disease, thyroid disease) • Complications (e.g., cellulitis, osteomyelitis) • Pain • Presence of: • Contractures • Dementia • Depression • Terminal illness

  13. Staging of pressure ulcers Suspected deep tissue injury Purple or maroon localized area of discolored intact skin or blood-filled blister due to damage of underlying soft tissue from pressure and/or shear*. The area may be preceded by tissue that is painful, firm, mushy, boggy, warmer or cooler as compared to adjacent tissue.Further description: Deep tissue injury may be difficult to detect in individuals with dark skin tones. Evolution may include a thin blister over a dark ulcer bed. The ulcer may further evolve and become covered by thin eschar*. Evolution may be rapid, exposing additional layers of tissue even with optimal treatment. Stage I Intact skin with nonblanchable redness of a localized area, usually over a bony prominence. Darkly pigmented skin may not have visible blanching; its color may differ from the surrounding area.Further description: The area may be painful, firm, soft, warmer or cooler as compared to adjacent tissue. Stage I may be difficult to detect in individuals with dark skin tones. May indicate “at risk” persons (a heralding sign of risk).

  14. Staging of pressure ulcers Stage II • Partial thickness loss of dermis presenting as a shallow open ulcer with a red pink ulcer bed, without slough*. May also present as an intact or open/ruptured serum-filled blister.Further description: Presents as a shiny or dry shallow ulcer without slough or bruising. This stage should not be used to describe skin tears, tape burns, perineal dermatitis, maceration* or excoriation.Bruising indicates suspected deep tissue injury

  15. Staging of pressure ulcers Stage III • Full thickness tissue loss. Subcutaneous fat may be visible but bone, tendon or muscle are not exposed. Slough may be present but does not obscure the depth of tissue loss. May include undermining* and tunneling*.Further description: The depth of a Stage III pressure ulcer varies by anatomical location. The bridge of the nose, ear, occiput and malleolus do not have subcutaneous tissue and Stage III ulcers can be shallow. In contrast, areas of significant adiposity can develop extremely deep Stage III pressure ulcers.Bone/tendon is not visible or directlypalpable.

  16. Staging of pressure ulcers Stage IV • Full thickness tissue loss with exposed bone, tendon or muscle. Slough or eschar may be present on some parts of the ulcer bed. Often include undermining and tunneling.Further description: The depth of a Stage 4 pressure ulcer varies by anatomical location. The bridge of the nose, ear, occiput and malleolus do not have subcutaneous tissue and these ulcers can be shallow. Stage 4 ulcers can extend into muscle and/or supporting structures (e.g., fascia, tendon or joint capsule)making osteomyelitis possible. Exposed bone/tendon is visible or directly palpable.

  17. Staging of pressure ulcers Unstageable • Full thickness tissue loss in which the base of the ulcer is covered by slough (yellow, tan, gray, green or brown) and/or eschar (tan, brown or black) in the ulcer bed.Further description: Until enough slough and/or eschar is removed to expose the base of the ulcer, the true depth, and therefore stage, cannot be determined. Stable (dry, adherent, intact without erythema* or fluctuance*) eschar on the heels serves as “the body’s natural (biological) cover” and should not be removed. • National Pressure Ulcer Advisory Panel, 2007

  18. Factors that can affect ulcer treatment and healing • Physiologic factors • Functional factors • Psychosocial factors • Ethical considerations

  19. Identify Priorities in managing the ulcer and the patient Effective management of a pressure ulcer requires: • Identification and treatment of causative factors when feasible, • Identification and treatment of modifiable comorbid conditions, • Provision of optimal nutritional support, • Determination of the best topical care to facilitate ulcer healing, • Prevention and management of infection* of the ulcer or adjacent tissue, and • Pain control related to the ulcer and any comorbid conditions.

  20. Prevention and Treatment • Pressure Ulcer Prevention Measures • Create a turning and positioning schedule that is based on the patient’s individual risk factors • Do not massage reddened areas over bony prominences • Evaluate and manage urinary and fecal incontinence • Initiate a plan to prevent or manage a contracture • Inspect skin during bathing or daily personal care • Maintain adequate nutrition and hydration if possible • Maintain the lowest possible head elevation to reduce the impact of shear • Position the patient to minimize pressure over bony prominences and shearing forces over the heels and elbows, base of head, and ears • Use appropriate offloading or pressure-redistribution devices • Use lifting devices such as draw sheets or a trapeze • Use proper transferring techniques

  21. Unavoidable Pressure Ulcers Under the surveyor guidance accompanying F314, an unavoidable pressure ulcer is a pressure ulcer that develops even though a facility has done the following: • Evaluated the patient’s clinical condition and risk factors; • Defined and implemented interventions consistent with patient needs, goals, and recognized standards of practice; • Monitored and evaluated the impact of these interventions; and • Revised the approaches as appropriate

  22. Unavoidable Pressure Ulcers The following clinical circumstances, among others, may impede or prevent healing or result in additional ulcer development that may be unavoidable: • Cachexia, • Metastatic cancer, • Multiple organ failure, • Sarcopenia, • Severe vascular compromise, and • Terminal illness.

  23. Nutrition • Increased protein intake is often emphasized in patients with nonhealing wounds; adequate intake of any single nutrient, however, does not prevent pressure ulcer formation or facilitate healing. • Many clinicians recommend caloric intake of 30 kcal/kg to 35 kcal/kg33 and daily protein intake of 1.2 to 1.5 g/kg of body weight34 for nutritionally compromised patients who have or are at risk of pressure ulcers

  24. Pain Management Pain management. After assessing pain and defining its characteristics (e.g., frequency, intensity, possible aggravating factors) and causes, treat it aggressively by using appropriate pain management protocols. (See AMDA’s 2003 clinical practice guideline, Pain Management in the Long-Term Care Setting

  25. Turning and Positioning Proper positioning, turning, and transferring techniques are important to manage pressure and shearing forces, ensure weight redistribution on support surfaces, and protect uninvolved skin. Evidence does not support any specific time interval for turning patients as a preventive or healing strategy for pressure ulcers

  26. Manage Pressure A systematic review of support surfaces for pressure ulcer prevention found that the use of ordinary foam mattresses (less than 4 inches thick) presented a higher risk of pressure ulcer development than the use of higher-specification mattresses.45 Patients at risk of skin breakdown should be placed on a static support surface (e.g., foam overlay, foam mattress, static flotation device) rather than on a standard mattress.

  27. Necrotic Tissue Pressure ulcer healing may be delayed by the presence of necrotic tissue, which also provides a medium for bacterial growth. Any necrotic tissue observed during assessment of the ulcer should be debrided, provided that this intervention is consistent with overall patient care goals.

  28. Debridement of an ulcer When choosing a debridement method, consider • Ulcer size, • Amount of slough and exudate, • Presence and severity of pain associated either with the ulcer or with the method of debridement, • Feasibility of performing sharp or surgical debridement, and • Risks of transporting the patient outside of the facility vs. the benefits of surgical debridement.

  29. Heel Ulcers It is generally recommended not to debride heel ulcers with dry, hard eschar unless there is edema, erythema, fluctuance, or drainage. Monitor heel ulcers closely for evidence of infection, at which time debridement should occur.

  30. Cleaning the wound An effective antiseptic should: • Act quickly; • Be nonirritating; • Be nontoxic to viable tissue; • Have a broad spectrum of activity; • Have low resistance potential; and • Work in the presence of blood, fibrin, pus, and slough

  31. Ulcer Dressings The goals of dressing an ulcer are to: • Keep the ulcer bed moist and the surrounding skin dry, • Protect the ulcer from contamination, and • Promote healing.

  32. Factors to Consider When Selecting Ulcer Care Products • Burden to patient (i.e., number of daily dressing changes required) • Cost-effectiveness of product • Costs of ancillary supplies and equipment associated with treatment • Ease of use and cost of staff time to use the product • Safety, efficacy, and likelihood and potential severity of complications • Ulcer characteristics (e.g., depth, condition of surrounding skin, location near sources of contamination, presence and amount of exudate)

  33. F314 Surveyor Guidance: Monitoring Considerations • Daily Monitoring • Evaluate ulcer if no dressing is present • Evaluate status of dressing if present: Is dressing intact? Is drainage present? If so, is it leaking? • Status of area surrounding ulcer that can be observed without removing the dressing • Presence of possible complications (e.g., signs of increasing area of ulceration, soft tissue infection) • Evaluate whether pain, if present, is adequately controlled • Document when a change or complication is identified

  34. F314 Surveyor Guidance: Monitoring Considerations Weekly or Dressing Change Monitoring • Location and staging of ulcer • Size (perpendicular measurement of greatest extent of length and width of ulceration); depth; and presence, location, and extent of undermining, tunneling, or sinus tract* • Presence of exudate; if present, type (e.g., purulent, serous), color, odor, approximate amount • Presence of pain; if present, nature and frequency (e.g., episodic, continuous) • Status of wound bed: color and type of tissue; evidence of healing (e.g., granulation tissue); necrosis (slough, eschar) • Description of wound edges and surrounding tissue (e.g., rolled edges, redness, hardness/induration, maceration)

  35. F314 Surveyor Guidance: Monitoring Considerations • Use of Photography in Pressure Ulcer Monitoring • Photography may be used in monitoring as part of the facility’s compliance efforts, if the facility has developed a protocol consistent with accepted standards, which include the following: • Frequency of use • Photos taken at a consistent distance from the wound • Type of photographic equipment used • Means to ensure that digital images are accurate and not modified • Inclusion of resident identification, ulcer location, dates, etc., within the photographic image • Parameters for comparison over time

  36. IMPORTANT! • It is important to establish goals consistent with the values and lifestyle of the individual and his/her family.
