Systematic wound evaluation, tissue types, and objective measurement technique
Wound assessment is a core clinical skill that drives treatment decisions and tracks healing progress. A complete, objective wound assessment requires systematic evaluation of the wound bed, wound edges, surrounding skin, drainage, odor, pain, and size — documented consistently so that changes over time are clearly visible in the clinical record.
Effective wound assessment follows a consistent structure so that nothing is missed and documentation supports care planning. The key components are: location, size, wound bed characteristics, wound edges, periwound skin, drainage, odor, pain, and signs of infection.
Document anatomical location precisely (e.g., "right lateral malleolus" not "right ankle"). Use body landmarks, not patient terms, to ensure consistency across caregivers. For pressure injuries, note the specific bony prominence.
Measure length (head-to-toe axis), width (side-to-side), and depth in centimeters. Use a sterile swab or probe inserted perpendicular to the wound bed for depth. For undermining or tunneling, document the clock-position and extent (e.g., "tunneling 2 cm at 12 o'clock position"). Photograph wounds when agency policy permits.
Identifying tissue type guides wound care decisions and reflects healing stage.
Beefy red, moist, granular-appearing tissue. Indicates active healing. A wound bed with more than 75% granulation is progressing well. Pale or dusky granulation may indicate poor perfusion or infection.
Yellow, tan, or gray stringy or mucinous tissue attached to the wound bed. Represents devitalized tissue that must be removed (debridement) to support healing. The presence of slough does not automatically indicate infection.
Black, brown, or tan hard, leathery devitalized tissue. Stable eschar on a heel — dry, intact, no signs of infection — may be left in place per physician order. Soft or fluctuant eschar should be reported and assessed for debridement.
Pink or purple tissue migrating from wound edges inward. Indicates the final stage of healing. Handle gently — this tissue is fragile.
Document drainage type (serous, serosanguineous, sanguineous, purulent), amount (scant, moderate, heavy), and color. Purulent drainage, increased warmth, erythema extending more than 2 cm from wound edges, edema, increased pain, and odor are signs of local infection requiring clinical notification. Systemic signs (fever, chills, elevated WBC) indicate possible spreading infection or sepsis — call 911.
Assess for erythema, induration, maceration (from excess moisture), desiccation (from too little moisture), or breakdown. Macerated periwound skin — whitened, soft, wrinkled — indicates excessive moisture exposure and requires dressing adjustment.
