Pressure ulcers, also known as bedsores, decubitus ulcers, or pressure injuries, represent a significant concern in healthcare. These localized injuries to the skin and underlying tissue typically arise from prolonged pressure, often over bony prominences. The sustained pressure disrupts blood flow, leading to ischemia, tissue damage, and ultimately, ulceration and necrosis. Understanding the risk factors and implementing preventive measures are crucial for nurses and healthcare providers. This article delves into the Nursing Diagnosis For Risk For Pressure Ulcers, providing a comprehensive overview of assessment, prevention, and care strategies.
Understanding Pressure Ulcers
Pressure ulcers primarily develop over bony prominences due to concentrated pressure. Common sites include the sacrum, coccyx, greater trochanter, heels, and lateral malleoli. The National Pressure Injury Advisory Panel (NPIAP) classification system standardizes pressure ulcer staging based on tissue involvement:
- Stage 1: Non-blanchable erythema of intact skin.
- Stage 2: Partial-thickness skin loss with exposed dermis.
- Stage 3: Full-thickness skin loss, involving subcutaneous fat.
- Stage 4: Full-thickness skin and tissue loss, exposing muscle, bone, tendon, ligament, or cartilage.
- Unstageable: Full-thickness tissue loss with the base of the ulcer covered by slough or eschar.
- Deep Tissue Pressure Injury (DTPI): Persistent non-blanchable deep red, maroon, or purple discoloration.
Preventing pressure ulcers is paramount as they can be challenging to treat and significantly impact patient morbidity. Stage 3 and 4 ulcers carry a heightened risk of severe complications such as osteomyelitis and sepsis. While simple wound care may suffice for early stages, advanced ulcers often require debridement, negative pressure wound therapy, hyperbaric oxygen therapy, or surgical intervention.
The Nursing Process and Pressure Ulcer Prevention
Effective pressure ulcer prevention necessitates a collaborative healthcare team approach. This includes implementing regular turning schedules, meticulous hygiene practices, nutritional support, and vigilant monitoring. Even with proactive preventive measures, high-risk patients can still develop pressure ulcers, emphasizing the nurse’s crucial role in early detection and diligent wound care to avert complications.
Nursing Assessment: Identifying Risk for Pressure Ulcers
The cornerstone of preventing pressure ulcers is a thorough nursing assessment. This involves gathering comprehensive patient data encompassing physical, psychosocial, emotional, and diagnostic aspects. Focusing on both subjective and objective data is essential for accurate risk identification and tailored intervention planning.
Review of Health History: Subjective Data Collection
1. Inquiry about Skin Changes: Initiate the assessment by directly asking the patient about any existing skin issues, particularly noting:
- Skin discoloration or unusual redness
- Any foul odor emanating from a specific area
- Presence of discharge or drainage
- Areas of decreased or altered sensation
2. Identifying Potential Causative Factors: Evaluate the patient’s skin condition and mobility status meticulously. Document any medical devices or equipment, such as diapers, intravenous lines, or urinary catheters, that could exert pressure on the skin. Recognize that the following factors, when combined with pressure, significantly elevate the risk of pressure ulcer development:
- Exposure to moisture from bodily fluids (perspiration, urine, or feces)
- Friction forces (skin rubbing against surfaces like bed linens)
- Shear forces (tissue layers sliding over each other, causing vascular damage)
3. Risk Factor Stratification: Determine the patient’s individual risk profile for pressure ulcer development. Patients exhibiting the following characteristics are considered at higher risk:
- Advanced age
- Immobility or bedridden status
- Paralysis
- Incontinence (urinary or fecal)
- Malnutrition
- Obesity or underweight status
- Impaired ability to communicate pain or discomfort
4. Medical Record Review: Scrutinize the patient’s medical history for pre-existing conditions that predispose them to pressure ulcers. Pay close attention to conditions that compromise mobility, sensory perception, or blood circulation:
- Conditions causing immobility:
- Paraplegia
- Quadriplegia
- Spina bifida
- Sensory perception deficits
- Conditions affecting peripheral vascular circulation
Note: Document the duration of the patient’s hospitalization, as prolonged stays correlate with an increased incidence of pressure ulcers.
5. Medication Review: Consider the patient’s medication regimen. Be aware of drug-induced pressure ulcers (DIPUs), a recognized adverse drug reaction, particularly linked to psychiatric medications in elderly individuals.
6. Socioeconomic and Support System Assessment: Evaluate the patient’s living situation and available support system. Stage 4 pressure ulcers can sometimes indicate neglect, especially in vulnerable populations like nursing home residents or home-care patients. Assess the adequacy of caregiver support and offer education to families and caregivers responsible for immobile patients.
7. Surgical History Review: Note any recent surgeries. Pressure ulcers can begin to form within hours of immobility, even during surgery. Prolonged anesthesia, lengthy surgical procedures, and post-operative reduced mobility are significant risk factors.
Physical Assessment: Objective Data Collection
1. Comprehensive Pressure Ulcer Assessment: If a pressure ulcer is present, conduct a detailed assessment, documenting:
- Size: Measure length, width, and depth in centimeters.
- Wound characteristics:
- Presence and type of exudate (serous, sanguineous, purulent)
- Presence of odor (foul or pungent)
- Undermining (tissue destruction extending under intact skin along wound edges)
- Tunneling (narrow passageway extending from the wound)
- Necrotic tissue (slough, eschar)
- Healing status: Presence of granulation tissue and epithelization
- Wound margins and periwound skin condition (erythema, induration, maceration)
2. Pressure Ulcer Staging: Accurately stage the pressure injury using the NPIAP classification system. Correct staging is crucial for monitoring wound progression or deterioration and guiding treatment.
3. Mental Status Evaluation: Assess the patient’s cognitive ability to communicate needs and perceive discomfort. Patient’s who are cognitively impaired may not be able to verbalize their needs for repositioning, toileting, or hydration, increasing their risk.
4. Neuromuscular and Mobility Status: Evaluate neuromuscular function and mobility level. Patients with sensory impairments (e.g., spinal cord injuries, neuropathy) may not perceive pressure or discomfort. Limited mobility, contractures, or paralysis necessitate proactive pressure ulcer prevention strategies.
5. Braden Scale Assessment: Utilize the Braden Scale, a widely validated tool for pressure ulcer risk assessment. Evaluate six subscales: sensory perception, moisture, activity, mobility, nutrition, and friction/shear. The total score categorizes risk level and guides individualized intervention planning.

Diagnostic Procedures
1. Blood Workup: Obtain blood samples for laboratory analysis. Certain values can provide insights into underlying causes or factors affecting wound healing:
- Elevated white blood cell (WBC) count: May indicate infection or inflammation.
- Low hemoglobin levels: Suggests reduced oxygen-carrying capacity to tissues.
- Low platelet count: Can impair wound healing processes like proliferation and angiogenesis.
- Low albumin levels: Indicate protein deficiency, hindering wound repair.
- Elevated glucose levels: Can negatively impact wound healing.
2. Wound Culture: If the pressure ulcer exhibits drainage or signs of infection, obtain a wound culture to identify the causative pathogen and guide antibiotic therapy.
3. Tissue Biopsy: Consider tissue biopsy for non-healing pressure ulcers to rule out underlying complications such as osteomyelitis or malignancy.
4. Imaging Studies: If osteomyelitis is suspected, MRI or CT scans may be indicated to evaluate bone involvement.
Nursing Interventions: Preventing and Treating Pressure Ulcers
Nursing interventions are crucial for both preventing pressure ulcers in at-risk individuals and effectively managing existing ulcers to promote healing and prevent complications.
Pressure Ulcer Prevention Strategies
1. Regular Repositioning and Turning: Implement a strict repositioning schedule, turning patients at least every two hours. Delegate turning schedules to unlicensed assistive personnel as appropriate. Encourage increased activity levels within patient capabilities, including passive and active range of motion exercises and ambulation.
2. Skin Hygiene and Moisture Management: Maintain meticulous skin hygiene, keeping the skin clean and dry. Utilize moisture barrier creams to protect skin from incontinence. Consider fecal and urinary diversion devices based on ulcer location and contamination risk.
3. Pressure-Relieving Support Surfaces: Employ specialty mattresses, cushions, foam wedges, and heel protectors to offload pressure from bony prominences.
4. Friction and Shear Reduction: Minimize friction and shear forces. Use transfer sheets when repositioning patients in bed. Keep the head of the bed as low as clinically possible to prevent patient sliding.
5. Hydration and Nutritional Optimization: Ensure adequate hydration and nutrition, particularly protein intake, to support skin health and tissue integrity. Hydration is crucial for cell function, collagen production, and skin elasticity.
6. Device and Line Management: Prevent pressure from medical devices (urinary catheters, IV lines, feeding tubes). Ensure linens and clothing are wrinkle-free under the patient.
7. Patient and Caregiver Education: Educate patients, families, and caregivers about pressure ulcer prevention. Emphasize:
- Adherence to turning and repositioning schedules.
- Maintaining clean and dry skin.
- Utilizing pressure-offloading devices.
- Recognizing early warning signs of skin breakdown (e.g., skin darkening, decreased sensation).

Treatment of Existing Pressure Ulcers
1. Pressure Relief and Protection: For Stage 1 pressure ulcers, focus on pressure offloading. Frequent repositioning, pressure-relieving mattresses, pillows, and wedges are essential. Consider applying a Mepilex Border dressing to sacral/coccyx or heel areas for protection against pressure, friction, and shear.
2. Wound Dressing Selection: Wound dressing choices depend on ulcer characteristics (drainage, infection status). Follow facility protocols or healthcare provider orders:
- Infected wounds, non-draining: Silver dressings, topical medical-grade honey, or foam dressings.
- Infected wounds, draining: Alginate, silver, gauze, or foam dressings.
- Non-infected wounds, non-draining: Hydrogel dressings.
- Non-infected wounds, draining: Alginate, hydrocolloid, gauze, or foam dressings.
3. Debridement Considerations: Debridement (removal of necrotic tissue) may be necessary for wound healing. Methods include moist dressings, enzymatic ointments, or surgical debridement by a wound care nurse or specialist.
4. Negative Pressure Wound Therapy (NPWT): Consider wound vacuum-assisted closure (VAC) for Stage 3 or 4 ulcers. NPWT promotes healing by removing exudate and reducing edema, stimulating granulation tissue formation, and drawing wound edges together.
5. Pain Management: Manage pain associated with wound care. Premedicate with analgesics as prescribed prior to painful procedures.
6. Surgical Intervention: Surgical debridement, skin grafts, or flap reconstruction may be needed for complex or non-healing wounds.
7. Hyperbaric Oxygen Therapy: Hyperbaric oxygen therapy can enhance wound oxygenation and promote healing in select cases.
8. Nutritional Consultation: Consult a dietitian to optimize nutritional support. Protein, macronutrients, and micronutrients (zinc, iron, vitamins C, E, A) are vital for wound healing.
9. Wound Care Specialist Referral: Refer complex or chronic pressure ulcers to a certified wound care nurse or specialist for expert management and treatment planning.
