1 Pressure Ulcers: Staging and Risk Assessment
Keri Holmes-Maybank, MD Medical University of South Carolina

2 Learning objectives Residents will be able to stage pressure ulcers in hospitalized patients. Residents will recognize the relationship between pressure ulcer healing and nutrition. Residents will recognize the importance of pressure ulcer prevention.  Residents will recognize the Braden Scale as a tool to identify patients at risk for pressure ulcer formation.

3 Key Messages In hospital pressure ulcer formation is on the rise.
Pressure ulcers lead to increased mortality, hospital cost, and length of stay. Staging of pressure ulcers is standardized by the National Pressure Ulcer Advisory Board. 99% of deep tissue injuries lead to stage III or Stage IV ulcers.

4 Pressure Ulcers

5 Pressure Ulcers 2.5 million hospitalized patients/yr
60,000 die/yr from pressure ulcer complications 1 in 25 if pressure ulcer reason for admit 1 in 8 if pressure ulcer secondary diagnosis 10-18% acute care patients 0.4-38% acute care new ulcers

6 Pressure Ulcers 80% increase pressure ulcer related hospitalizations Length of Stay days (average LOS 5 days) $ billion in 2008 awards avg $13.5 million $312 million in one case

7 Impact on Patients Reduces quality of life
Interfere with basic activities of daily living Increased pain Decrease functional ability Infection – OM and septicemia Increase length of stay Premature mortality Deformity

8 Pressure Ulcer Localized injury to the skin and/or underlying tissue
0ver a bony prominence Result of pressure, or pressure in combination with shear.

9 Pressure Pressure is the force that is applied perpendicular to the surface of the skin. Compresses underlying tissue and small blood vessels hindering blood flow and nutrient supply. Tissues become ischemic and are damaged or die.

10 Shear Shear occurs when one layer of tissue slides horizontally over another, deforming adipose and muscle tissue, and disrupting blood flow. Ex: when the head of the bed is raised > 30 degrees.

11 Bony Prominences Occiput Ear Scapula Spinous Process Shoulder Elbow
Iliac Crest Sacrum/Coccyx Ischial Tuberosity Trochanter Knee Malleolus Heel Toe

12 Bony Prominences

13 Additional Areas Any skin surface subjected to excess pressure
Oxygen tubing Drainage tubing Casts Cervical collars

14 Time to Pressure Ulcer Bed bound individuals form a pressure ulcer in as little as 1-2 hours. Those in chairs may form a pressure ulcer in even less times because of greater relative force on skin.

15 Risk Assessment Expert panels recommend use of risk assessment tools.
Tool is better than clinical judgment alone. Scores are predictive of pressure ulcer formation. Patients with a risk assessment have better documentation and more likely to have prevention initiated. Braden Scale

16 Who do you screen? Limited ability to reposition self in bed or chair
Stroke with residual deficits Post-surgical Paraplegic Quadraplegic Wheelchair bound Bed bound

17 Braden Scale Sensory perception Moisture
Activity - degree of physical activity Mobility – ability to change body position Nutrition Friction and Shear

18

19 Braden Scale – Sensory Perception
Ability to respond meaningfully to pressure- related discomfort. Completely Limited No moan/flinch, cannot feel pain most of body Very Limited – Responds only to pain, cannot feel pain ½ body Slightly Limited – Responds to command, cannot feel pain 1-2 limbs No Impairment

20 Braden Scale - Moisture
Degree to which skin is exposed to moisture. Constantly Moist Very Moist Often but not always, change sheets each shift Occasionally Moist Extra linen change a day Rarely Moist Only routine linen change

21 Braden Scale - Activity
Degree of physical activity. Bedfast Chairfast Assisted into chair, cannot or barely walk Walks Occasionally Very short distance, most shift in bed Walks Frequently Walks outside room or in room every 2 hours

22 Braden Scale - Mobility
Ability to change and control body position. Completely Immobile Very Limited Unable to make frequent or significant changes Slightly Limited Makes frequent but small changes No Limitation

23 Braden Scale - Nutrition
Usual food intake pattern. Very Poor 1/3 meal, <2 servings protein, NPO w IVF Probably Inadequate ½ meal, 3 servings protein, poor tube feeds Adequate >1/2 meals, 4 servings protein, supps, TF or TPN Excellent

24 Braden Scale – Friction and Shear
Sliding, rubbing against sheets, bed, chair, etc. Problem Mod-max assist, slides, cannot move without slide against sheets, spasticity, contractures, agitation Potential Problem Feeble, min assist, occ slides, indep moves with slide No Apparent Problem

25 Braden Scale Braden Scale score of 18 or less initiate prevention.
Score of 1 or 2 initiate specialty bed.

27 Partial and Full Thickness
Partial thickness wound involves ONLY the epidermis and dermis – Stage II. Full thickness wound involves the epidermis and dermis and extends into deeper tissues (subcutaneous fat, muscle) – Stages III and IV.

28 Non-Blanchable Erythema
The ulcer appears as a defined area of redness that does not blanch (become pale) under applied light pressure – Stage I.

29 Undermining Tissue destruction underneath intact skin at the wound edge. Wound edges are not attached to the wound base. Edges overhang the periphery of the wound. Pressure ulcer may be larger in area under the skin surface.

30 Undermining

31 Tunneling Tunnel is a narrow channel of tissue loss that can extend in any direction away from the wound through soft tissue and muscle. Tunnel may result in dead space which can complicate wound healing. Depth of the tunnel can be measured using a cotton-tipped applicator or gloved finger.

32 Tunneling

33 Stage I

34 Stage I INTACT SKIN. NON-BLANCHABLE redness of a localized area.
Difficult to detect in individuals with dark skin tones - affected site is deeper in color. Surrounding skin will feel different than effected area. May indicate “at risk” persons.

35 Stage I

36 Stage II

37 Stage II Partial thickness loss of dermis presenting as shallow open ulcer with a RED-PINK wound bed. Shiny or dry shallow ulcer. No slough or bruising. BLISTER - intact, open or ruptured serum or serosangineous-filled. Tissue surrounding the areas of epidermal loss are erythemic.

38 Stage II

39 Stage III

40 Stage III FULL-THICKNESS tissue loss. Subcutaneous fat may be visible.
Bone, tendon, or muscle is NOT visible or directly palpable. Slough may be present but does NOT obscure the depth of tissue loss. May include undermining and tunneling.

41 Stage III 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 so Stage III ulcers can be shallow. Areas of significant adiposity can develop extremely deep Stage III pressure ulcers.

42 Stage III

43 Stage IV

44 Stage IV FULL-THICKNESS tissue loss.
BONE, TENDON, or MUSCLE is visible or directly palpable. Slough or eschar may be present but does NOT obscure wound bed. Often includes undermining and tunneling. Can extend into supporting structures (fascia, tendon or joint capsule) making osteomyelitis or osteitis likely .

45 Stage IV The depth of a Stage IV 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.

46 Stage IV

47 Unstageable

48 Unstageable FULL-THICKNESS tissue loss in which SLOUGH (yellow, tan, gray, green, or brown), ESCHAR (tan, brown, or black), or both COVER the base of the ulcer. Cannot determine true depth of wound secondary to slough and/or eschar. Will be either a Stage III or IV.

49 Unstageable

50 Deep Tissue Injury

51 Deep Tissue Injury INTACT SKIN. PURPLE or MAROON.
BLOOD FILLED BLISTER. May be difficult to detect in individuals with dark skin tones. Color and mechanical stiffness of the skin (firm, mushy, boggy) assist in differentiating between DTI and a Stage I pressure ulcer.

52 Deep Tissue Injury Most common:
Sacrum, buttocks and heels. Heel may look like a bruise or a blood blister. 1% resolve spontaneously. Evolution: Thin blister over a dark wound bed. Covered by thin eschar. May rapidly evolve. Likely become a Stage III or IV.

53 Deep Tissue Injury

54 Not Pressure Ulcers Skin Tears Venous Ulcers Arterial Ulcers
Diabetic Ulcers Perineal (Incontinence Associated) Dermatitis

55 Skin Tear Separation of epidermis from the dermis or epidermis and dermis from underlying tissue. Thin skin, less elastic, purpura or ecchymosis. Epidermal flap.

56 Arterial Ulcers Impaired arterial flow to the lower leg and foot.
Tissue ischemia, necrosis and loss WELL DEFINED MARGINS Toes, foot, malleolus Thin, shiny skin, cool skin temperature, decreased or absent hair Painful - increase with elevation Decreased pulse Minimal exudate Pale wound bed; necrotic tissue

57 Venous Ulcers Decrease in blood return from leg and foot.
Between the knee and the ankle. Thickened, brown discolored skin is noted around the lower calf, ankle and proximal foot. Skin proximal and distal to the wound is reddened.

58 Diabetic Ulcers Ulcer that occurs in diabetics
Metatarsal head, top of toes, and foot Neuropathy, poor microvascular circulation Repetitive trauma, unperceived pressure, or friction/shear Regular wound margins Callus around wound Dry, cracked, warm

59 Perineal Dermatitis (Incontinence Associated)
Skin irritation from incontinence. Erosion of epidermis and dermis from mechanical injury to macerated skin. Buttocks, perineum, and upper thighs. Secondary infection. Diffuse erythema. Scaling, papule and vesicle formation . Tissue “weeping”.
