Pressure Ulcer Prevention and Treatment in Nursing Homes

Pressure ulcers — also called pressure injuries, decubitus ulcers, or bedsores — represent one of the most closely monitored quality indicators in long-term care. Federal regulators classify their development as a potential marker of substandard nursing home care, making prevention protocols and treatment documentation central to both resident safety and regulatory compliance. This page covers the clinical definition and staging classifications, the mechanisms underlying prevention and treatment frameworks, the common scenarios in which pressure injuries arise or escalate in nursing facilities, and the regulatory and clinical boundaries that govern facility responses.

Definition and Scope

A pressure ulcer is localized damage to the skin and underlying soft tissue, typically over a bony prominence, resulting from sustained pressure, shear, friction, or a combination of these forces. The National Pressure Injury Advisory Panel (NPIAP) — the primary standards body for pressure injury nomenclature in the United States — revised its classification terminology in 2016 from "pressure ulcer" to "pressure injury," though federal regulatory language in the Code of Federal Regulations at 42 CFR §483.25(b) retains the term "pressure sore" and "pressure ulcer" for survey and enforcement purposes.

The NPIAP staging system defines six discrete categories:

1. Stage 1 — Non-blanchable erythema of intact skin; underlying tissue may feel firmer or softer than adjacent tissue.
2. Stage 2 — Partial-thickness skin loss with exposed dermis; wound bed is viable, pink, or red and moist. No slough or eschar.
3. Stage 3 — Full-thickness skin loss; subcutaneous fat may be visible, but bone, tendon, and muscle are not exposed. Depth varies by anatomical location.
4. Stage 4 — Full-thickness skin and tissue loss with exposed or directly palpable bone, tendon, or muscle. Slough and eschar may be present.
5. Unstageable — Full-thickness skin and tissue loss where extent cannot be determined because the wound base is obscured by slough or eschar.
6. Deep Tissue Pressure Injury (DTPI) — Persistent, non-blanchable, deep red, maroon, or purple discoloration indicating damage to underlying soft tissue, often with intact overlying skin.

Moisture-associated skin damage (MASD), skin tears, and arterial or venous ulcers fall outside this classification system and require distinct clinical pathways, though they are tracked separately under CMS Minimum Data Set (MDS) Section M.

The scope of the problem in nursing facilities is significant. The Agency for Healthcare Research and Quality (AHRQ) has identified pressure ulcers as a leading patient safety concern in institutional care settings. Facilities that accept Medicare and Medicaid funding are bound by Federal nursing home requirements at 42 CFR Part 483, which mandate that residents who are admitted without pressure ulcers do not develop them unless clinically unavoidable, and that residents admitted with existing ulcers receive treatment to promote healing.

How It Works

Pressure injury prevention and treatment in nursing homes operates through a structured, interdisciplinary framework tied directly to the Resident Assessment Instrument (RAI) process. The care planning and interdisciplinary team coordinates assessment findings into individualized prevention and treatment plans.

Prevention Framework — Four Core Elements:

1. Risk Assessment — Facilities use validated tools such as the Braden Scale or Norton Scale to quantify pressure ulcer risk. The Braden Scale scores residents across 6 subscales (sensory perception, moisture, activity, mobility, nutrition, and friction/shear), with scores at or below 18 indicating at-risk status. Risk assessments are required at admission, with each significant change of condition, and at quarterly intervals per RAI protocol.

2. Repositioning and Offloading — Residents assessed as at-risk must be repositioned at scheduled intervals — commonly every 2 hours when in bed, and every 1 hour when seated. Heel offloading devices, foam wedges, and specialty mattresses are deployed based on risk tier.

3. Pressure-Redistributing Support Surfaces — AHRQ clinical practice guidelines distinguish between reactive support surfaces (which respond to applied load) and active support surfaces (which cycle pressure independently). Stage 3 and Stage 4 injuries typically warrant active surfaces.

4. Nutritional Management — Protein-calorie malnutrition impairs wound healing and skin integrity. Nutritional and dietary services are integrated into pressure ulcer care plans, with dietitian involvement required when wounds fail to progress. Serum albumin, prealbumin, and body weight trends inform supplementation decisions.

Treatment Framework — Wound Care Protocol:

Once a pressure injury is identified, wound care services initiate a structured treatment protocol aligned with NPIAP clinical guidelines. Core elements include wound bed preparation (debridement of necrotic tissue), moisture balance management using appropriate dressings (hydrocolloid, foam, alginate, or antimicrobial dressings based on exudate level), infection surveillance and management, and pain control. Pain management protocols are a required component of active wound care plans under 42 CFR §483.25.

Wound reassessment must occur at a minimum weekly, with documentation of wound dimensions (length, width, depth in centimeters), wound bed characteristics, exudate type and quantity, and periwound skin condition. Failure to document wound progress constitutes a surveyable deficiency under CMS survey protocols.

Common Scenarios

Scenario 1: Hospital-Acquired Pressure Injury on Admission
Residents transferred from acute care settings frequently arrive with Stage 2 or higher pressure injuries, particularly over the sacrum, coccyx, or heels. Federal regulations require that admitting facilities conduct a skin assessment within 24 hours and document wound status at baseline before assuming treatment responsibility. The transitional care from hospital to skilled nursing facility process determines how pre-existing injuries are documented and distinguished from facility-acquired wounds for survey purposes.

Scenario 2: Immobile Resident with Nutritional Deficits
Long-term residents with advanced dementia, contractures, or end-stage disease often present with overlapping pressure ulcer risk factors — immobility, incontinence, and protein-calorie malnutrition simultaneously. Dementia and memory care medical services teams frequently manage repositioning compliance challenges, and certified nursing assistants bear primary responsibility for executing scheduled turning and skin inspection protocols.

Scenario 3: Heel Pressure Injuries in Diabetic Residents
Residents with peripheral neuropathy from diabetes are at elevated risk for undetected heel pressure injuries due to diminished sensation. Diabetes management in nursing home residents protocols intersect with pressure ulcer prevention here; vascular status assessment and podiatry services are integrated into the wound care plan when arterial insufficiency complicates healing.

Scenario 4: Unstageable Wound Following Incontinence-Related Skin Breakdown
Moisture-associated skin damage from urinary or fecal incontinence can co-exist with or mask pressure injuries. Distinguishing MASD from a Stage 2 pressure injury requires clinical assessment of wound location (MASD tends to be diffuse rather than focal over a bony prominence), wound geometry, and moisture exposure history. Misclassification carries regulatory risk.

Decision Boundaries

Clinically Unavoidable vs. Facility-Acquired Distinction
The regulatory boundary established at 42 CFR §483.25(b) distinguishes between pressure injuries that develop despite consistent application of evidence-based prevention measures and those that represent preventable failures of care. CMS Survey and Certification guidance — specifically the State Operations Manual (SOM) Appendix PP — outlines the criteria surveyors use to determine whether a pressure ulcer is "unavoidable." Documentation of individualized risk assessment, a care plan with specific interventions, consistent implementation, and outcome monitoring constitutes the evidentiary standard.

Staging Authority and Reverse Staging
NPIAP explicitly prohibits "reverse staging" — the practice of reclassifying a healing wound backward through stages (e.g., calling a healing Stage 4 wound a Stage 3). A Stage 4 wound healed by secondary intention remains a healed Stage 4. This distinction matters for MDS and Resident Assessment Instruments coding accuracy, as MDS Section M codes wounds at their highest confirmed stage regardless of current healing status.

Surgical Wound Consultation Threshold
Stage 3 and Stage 4 wounds with undermining, tunneling, or exposed bone may require surgical debridement, flap consultation, or infectious disease involvement. The nursing home medical director role includes oversight of transfer-or-treat decisions at this clinical threshold.
