Wound Assessment: Part 1 Dot Weir, RN, CWON, CWS

Objectives 1. To describe the rationale for accurate wound assessment and documentation. 2. To recall the most common elements of a wound assessment. 3. To identify important aspects of soft tissue, wound characteristics and underlying structures.

Wound Assessment Keypoints • Foundation for developing goals and plan of care • Ultimate driver of treatment decisions (wounds are dynamic / may change often) • Evaluation of progress towards meeting goals of care (change from previous assessments) • Important to have common language to facilitate consistent documentation van Rijswijk, L, Eisenberg, M. (2014) Wound assessment and documentation. In: Krasner, D. L. (Ed). Chronic Wound Care: The Essentials. Malvern, PA. , HMP Communications

Wound Assessment Frequency and Documentation • Complete assessment generally performed weekly - Evaluation of wound status : every dressing change - Observe for significant changes both positive and negative that may require treatment change • Document per facility / agency protocol

Elements of the Wound Assessment • Wound Etiology - Location • Measurements - Surface area - Depth - Undermining, tracts & tunneling • Exudate - Color - Character • Tissue Type - Eschar - Slough - Granulation tissue - Epithelium • Wound Edges & Surrounding Skin • Structure - Bone - Tendon

Location • Important to document correct anatomical location • Use descriptors such as proximal/distal, anterior/posterior, superior/inferior with multiple wounds Left trochanter and left iliac crest versus left hip. Left scapula versus left shoulder

Wound Etiology • Diagnosis established by health care provider - Accurate diagnosis critical to guide treatment and goals of care (e. g. topical versus medical or combination of both) - Lower extremity wounds frequently have mixed etiology - Skin cancers may appear as small open area that fails to heal • If wound is not progressing as expected with current management, look further/revisit treatment plan

Common Wound Etiologies Diabetic foot ulcer Surgical Peripheral Arterial Disease Misc. Atypical Wounds Trauma Skin Cancer Pressure Ulcer Burn Venous Ulcer

Wound Measurements • Initial wound measurements critical as baseline to assess healing progress • Length multiplied by the width will provide approximate (though usually overstated) surface area • Length X Width X Depth can be calculated to provide approximate volume (using electronic medical records)

Wound Measurements – Length and Width • Measure longest length of the wound and widest then perpendicular line to that for width

Wound Measurements – Depth • Insert cotton end of sterile applicator into deepest part of wound at 90° angle to skin • Grasp applicator at skin level, remove and measure using disposable measuring guide.

Undermining and Tracts • Undermining is an area or space parallel to the skin • Tracts (also called sinus tracts or tunneling) are narrow areas that extend beyond the depth or edge of the wound • Important to assess, measure and document to guide treatment related to dressings and packing and to establish a baseline to assess healing

Undermining, Tracts and Depth Measurements: Document Using a “Clock” Method “Undermining 5 cm from 12 to 3 o’clock”

Drainage or Exudate: Amount Assessing amount is inexact unless dressings are weighed which is only done in clinical trials Assess to the extent possible knowing when the last dressing was changed Examples of estimating amount: • Changed 1 week ago = Small • Changed 2 days ago = Moderate • Changed 1 hour ago = Large

Drainage or Exudate: Color • Describe what you see • Impacted by previous treatments, bacteria • Common colors: Red, yellow, pink, tan, green

Drainage or Exudate: Character • Common terms: - Serous: clear light yellow - Serosanguinous: clear pink/yellow - Sanguineous: red/bloody - Purulent: Usually white/tan, may be tinged with other colors, opaque, cloudy • Use caution using the term purulent! Exudate may be byproduct of treatment: Autolysis, enzymatic debridement, cellular tissue products that have biodegraded, silver nitrate or other silver products

Exudate Character: Examples Serosanguinous Predominately serous Sanguineous

Exudate Character: Examples Tan Purulent Green Purulent Previous treatment residue; enzymatic ointment in use, expected outcome.

Exudate Character: Previous Treatment Residue

Tissue Types • Eschar: Dark in color, may be dry or moist • Slough: Necrotic tissue at some level of liquefying, may be dry or moist • Granulation: Wound in process of healing, tissue pink or red, granular in appearance • Clean non-granular: Wound bed pink or red but no evidence of healing • Hyper-granulation tissue: Tissue growth above the level of the skin

Granulation Tissue Pink, Non-Granular Red, Granular

Hyper-granulation Tissue

Epithelium • Migration of cells from the edge of the wound to resurface • May be evident, or may be thin layer which gives surface of wound a matte appearance • May originate in center of wound from structures such as hair follicles

Wound Edges and Surrounding Skin • Assessing edges provides evidence of: - Trauma: Callous, tearing - Inadequate wound surface: Cells thickened at edge - Epibole: Rolled edges, migration of cells down the wound edge closing them in

Callous/Rolled Edges

Epibole/Rolled Edges

Thickened

Surrounding Skin • Identify Potential Issues - Maceration - Erythema (Infection? ) - Rash • • • Reaction to treatment Fungal growth Excoriation Itching

Rash Reaction to Treatment Fungal Infection

Excoriation

Structures • Recognizing visible or palpable deep structures such as bone, tendon or fascia is critical - Potential for migrating infection or osteomyelitis - Need to maintain moisture to prevent drying

Bone • White, firm, shiny, either visually present in the wound, noted when cleansing or felt when gently probing deeper wound

Fascia • Dense fibrous connective tissue that surrounds the muscles, bones, nerves and blood vessels

Tendon • Cords of tough, fibrous connective tissue; glistening white in color

Summary • Accurate assessment is foundation for developing plan and goals of care • Accurate assessment guides wound treatment decisions • Accurate assessment and documentation is foundation for evaluating progress towards meeting goals of care (change from previous assessments)
