How to Perform a Skin Assessment

Skin integrity serves as a primary quality indicator in healthcare. Hospital-acquired pressure injuries (HAPIs) are classified as “never events” by Medicare, indicating preventable error. Proficiency in Skin Assessment and the Braden Scale is mandatory for nursing students to ensure patient safety and regulatory compliance. This guide delineates systematic evaluation protocols and evidence-based prevention strategies.

Skin Assessment Protocols

Effective assessment requires systematic inspection and palpation to evaluate color, temperature, moisture, turgor, and integrity.

The National Pressure Injury Advisory Panel (NPIAP) identifies the differentiation between blanchable and non-blanchable erythema as the critical step in preventing Stage 1 injury progression.

Inspection Techniques

Remove all compression devices and linens. Inspect bony prominences: Sacrum, Coccyx, Heels, Ischial Tuberosities, Elbows, Scapula, and Occiput. Check skin under medical devices (cannulas, catheters, braces) for device-related pressure injuries.

Palpation Techniques

• Blanching Test: Apply light pressure to reddened areas. If color fades (whitens) and returns, microcirculation is intact (Blanchable). If redness persists, capillary beds are damaged (Non-blanchable/Stage 1).
• Induration: Palpate for hardness or “bogginess” compared to surrounding tissue.
• Temperature: Use the dorsal hand surface. Warmth indicates inflammation/infection; coolness indicates ischemia.

Braden Scale Scoring Criteria

The Braden Scale (Range 6-23) predicts pressure injury risk based on six subscales. Lower scores indicate higher risk.

1. Sensory Perception (Ability to respond to pressure)

• 1 (Completely Limited): Unresponsive to pain (e.g., Coma, deep sedation).
• 2 (Very Limited): Responds only to painful stimuli; cannot communicate discomfort.
• 3 (Slightly Limited): Responds to verbal commands but has some sensory deficit (e.g., neuropathy).
• 4 (No Impairment): Responds to verbal commands; no sensory deficit.

2. Moisture (Degree of skin exposure)

• 1 (Constantly Moist): Skin wet due to perspiration/urine. Dampness detected every time patient is turned.
• 2 (Very Moist): Linen changes needed at least once/shift.
• 3 (Occasionally Moist): Linen changes approx. once/day.
• 4 (Rarely Moist): Skin usually dry.

3. Activity (Degree of physical activity)

• 1 (Bedfast): Confined to bed.
• 2 (Chairfast): Ability to walk severely limited or non-existent. Cannot bear weight.
• 3 (Walks Occasionally): Walks short distances with/without assistance during shift.
• 4 (Walks Frequently): Ambulates outside room at least twice daily.

4. Mobility (Ability to change body position)

• 1 (Completely Immobile): Does not make even slight changes without assistance.
• 2 (Very Limited): Makes occasional slight changes in body or extremity position but unable to make frequent/significant turns.
• 3 (Slightly Limited): Makes frequent though slight changes independently.
• 4 (No Limitation): Makes major and frequent changes independently.

5. Nutrition (Usual food intake)

• 1 (Very Poor): Never eats a complete meal. Takes fluid poorly. NPO and/or clear liquids or IVs for >5 days.
• 2 (Probably Inadequate): Rarel eats a complete meal (1/2 of food offered).
• 3 (Adequate): Eats over half of most meals. Eats a specified protein source.
• 4 (Excellent): Eats most of every meal. Never refuses a meal.

6. Friction and Shear

• 1 (Problem): Requires moderate to max assist. Spasticity, contractures, or agitation leads to sliding.
• 2 (Potential Problem): Moves feebly or requires min assist. Skin likely slides against sheets during move.
• 3 (No Apparent Problem): Moves in bed and chair independently. Lifts self completely during move.

Risk-Based Prevention Protocols

Interventions must correspond to the identified risk level.

• At Risk (15-18): Turn schedule (q2h), maximal remobilization, heel protection.
• Moderate Risk (13-14): Above interventions + 30-degree lateral incline position, foam wedges, moisture barrier creams.
• High Risk (10-12): Above interventions + increased turning frequency, dietary consult for supplements.
• Very High Risk (≤9): Above interventions + pressure-redistributing support surface (e.g., air-fluidized bed), manage moisture/incontinence aggressively.

Pressure Injury Staging System

Correct staging determines treatment and reimbursement.

• Stage 1: Intact skin with non-blanchable erythema.
• Stage 2: Partial-thickness loss of skin with exposed dermis. Wound bed is viable, pink/red, moist. May present as an intact or ruptured serum-filled blister. Excludes: Skin tears, burns, moisture-associated dermatitis.
• Stage 3: Full-thickness skin loss. Adipose (fat) is visible. Granulation tissue and epibole (rolled edges) often present. Slough/eschar may be visible. Undermining/tunneling may occur.
• Stage 4: Full-thickness skin and tissue loss. Exposed or directly palpable fascia, muscle, tendon, ligament, cartilage, or bone. Slough/eschar likely.
• Unstageable: Obscured full-thickness skin and tissue loss. Extent of damage cannot be confirmed because it is covered by slough or eschar. Action: If slough is removed, it will be Stage 3 or 4.
• Deep Tissue Injury (DTI): Persistent non-blanchable deep red, maroon, or purple discoloration. Skin may be intact or non-intact. Results from intense/prolonged pressure and shear at the bone-muscle interface.

Documentation Standards: REEDA

Document findings precisely using the REEDA acronym:

• Redness (Erythema)
• Edema (Swelling)
• Ecchymosis (Bruising)
• Discharge (Type: Serous, Sanguineous, Purulent / Amount / Odor)
• Approximation (Wound edges closed/open)

Measurements: Always measure Length (head-to-toe) x Width (side-to-side) x Depth. Use a clock face to describe tunneling (e.g., “3cm tunnel at 4 o’clock”).

Conclusion

Skin assessment is a fundamental nursing responsibility directly linked to patient outcomes. Proficiency in the Braden Scale and staging protocols enables early intervention, preventing the severe complications associated with pressure injuries.
