Introduction to Pressure Ulcers
Key Learning Objective
Understanding pressure ulcers is fundamental to nursing practice as they represent one of the most preventable healthcare complications, affecting millions of patients worldwide and significantly impacting quality of life.
Pressure ulcers, also known as bedsores or decubitus ulcers, are localized injuries to the skin and underlying tissues that result from prolonged pressure, friction, or shear forces. These injuries primarily occur over bony prominences and represent a significant healthcare challenge, affecting approximately 2.5 million patients annually in the United States alone.
The development of pressure ulcers involves complex pathophysiological processes that nurses must understand to provide effective care. When external pressure exceeds capillary perfusion pressure (typically 32 mmHg), tissue ischemia occurs, leading to cellular hypoxia and eventual tissue death if pressure is not relieved.
Clinical Significance
- • Healthcare-associated infections increase by 50% with pressure ulcers
- • Average treatment cost ranges from $500 to $70,000 per ulcer
- • Mortality rates increase by 2.8 times in patients with pressure ulcers
- • Hospital stays extend by an average of 4.31 days
Prevalence Statistics
- • Acute care: 8-12% of patients
- • Long-term care: 15-25% of residents
- • Home care: 17% of patients
- • ICU settings: Up to 40% of patients
Timeline of Development
- • Stage 1: 1-6 hours of pressure
- • Stage 2: 6-24 hours of pressure
- • Stage 3: 1-5 days of pressure
- • Stage 4: 5+ days of pressure
Causes and Risk Factors
Mnemonic: “PRESSURE” for Risk Factors
P – Prolonged immobility
R – Reduced sensation
E – Excessive moisture
S – Skin fragility
S – Shear and friction forces
U – Undernutrition
R – Reduced perfusion
E – Elderly population
Primary Causes
Pressure
Sustained compression of tissues between bony prominences and external surfaces, compromising blood flow and oxygen delivery.
Shear
Parallel forces causing tissue layers to slide against each other, typically occurring when patients slide down in bed.
Friction
Resistance to motion between skin and contact surfaces, particularly problematic during patient repositioning.
Comprehensive Risk Assessment
| Risk Category | Specific Factors | Mechanism | Nursing Implications |
|---|---|---|---|
| Mobility Impairment | Paralysis, sedation, cognitive impairment, musculoskeletal disorders | Inability to relieve pressure independently | Implement turning schedules, use pressure-redistributing devices |
| Sensory Impairment | Spinal cord injury, neuropathy, medication effects | Lack of awareness of pressure or discomfort | Educate on skin inspection, provide sensory substitutes |
| Nutritional Deficiency | Protein malnutrition, dehydration, vitamin deficiencies | Compromised tissue integrity and healing capacity | Nutritional assessment, dietary supplements, hydration management |
| Circulatory Compromise | Hypotension, anemia, peripheral vascular disease | Reduced tissue perfusion and oxygen delivery | Monitor vital signs, optimize circulation, positioning |
| Skin Moisture | Incontinence, perspiration, wound drainage | Maceration and weakening of skin barrier | Moisture management, barrier products, frequent cleansing |
High-Risk Populations
Medical Conditions
- • Diabetes mellitus
- • Cardiovascular disease
- • Kidney disease
- • Cerebrovascular accidents
Patient Populations
- • Elderly patients (>65 years)
- • ICU patients
- • Surgical patients
- • Patients with spinal cord injuries
Stages and Classifications
The National Pressure Ulcer Advisory Panel (NPUAP) classification system provides a standardized approach to categorizing pressure ulcers based on the depth of tissue involvement. Understanding these stages is crucial for nursing assessment and treatment planning.
Stage 1: Non-Blanchable Erythema
Appearance: Intact skin with localized area of non-blanchable erythema
Characteristics: May appear darker in darkly pigmented skin
Symptoms: Warmth, edema, induration, or hardness
Reversibility: Fully reversible with pressure relief
Stage 2: Partial Thickness Loss
Appearance: Partial thickness loss of dermis
Characteristics: Shallow open ulcer with red/pink wound bed
Symptoms: May present as intact or ruptured serum-filled blister
Healing time: 3-21 days with proper treatment
Stage 3: Full Thickness Loss
Appearance: Full thickness tissue loss with visible fat
Characteristics: Subcutaneous fat may be visible but not bone, tendon, or muscle
Symptoms: Slough may be present, undermining possible
Healing time: 1-6 months depending on size and location
Stage 4: Full Thickness Loss with Exposed Structures
Appearance: Full thickness tissue loss with exposed bone, tendon, or muscle
Characteristics: Slough or eschar may be present
Symptoms: Often includes undermining and tunneling
Healing time: 3 months to 2+ years, may require surgical intervention
Additional Classifications
Unstageable
Full thickness tissue loss where the base of the ulcer is covered by slough and/or eschar in the wound bed, making depth assessment impossible.
Suspected Deep Tissue Injury
Purple or maroon localized area of discolored intact skin or blood-filled blister due to damage of underlying soft tissue from pressure and/or shear.
Mnemonic: “SKIN” for Stage Assessment
S – Surface integrity (intact vs. broken)
K – Knowledge of tissue layers involved
I – Identify depth of tissue loss
N – Note presence of slough or eschar
Assessment Tools and Techniques
The Braden Scale: Gold Standard Assessment
The Braden Scale is the most widely used tool for assessing pressure ulcer risk, evaluating six key factors with scores ranging from 6-23, where lower scores indicate higher risk.
| Braden Scale Component | Score Range | Assessment Criteria | Nursing Considerations |
|---|---|---|---|
| Sensory Perception | 1-4 | Ability to respond meaningfully to pressure-related discomfort | Assess cognitive function, pain perception, consciousness level |
| Moisture | 1-4 | Degree to which skin is exposed to moisture | Evaluate incontinence, perspiration, drainage |
| Activity | 1-4 | Degree of physical activity | Assess mobility limitations, bedrest requirements |
| Mobility | 1-4 | Ability to change and control body position | Evaluate range of motion, turning ability |
| Nutrition | 1-4 | Usual food intake pattern | Assess dietary intake, albumin levels, weight changes |
| Friction and Shear | 1-3 | Degree of assistance needed for movement | Evaluate sliding, repositioning needs |
19-23 Points
