The Four Stages of Bedsores: Medical and Legal Implications in California

Bedsores are among the most painful and preventable injuries a nursing home resident can suffer, and by the time a family notices one, the facility has usually had multiple opportunities to stop it. At The Elder Justice Firm, we represent California families when pressure ulcers develop because a nursing home failed to provide basic care. Understanding the four stages of bedsores, what they mean medically, and what they mean legally is the first step toward knowing whether your loved one has a viable claim.

What Are Bedsores?

Bedsores, also called pressure ulcers or decubitus ulcers, are wounds that form when prolonged, unrelieved pressure cuts off blood flow to a specific area of skin and underlying tissue. Without oxygen, cells die and tissue breaks down. According to the CDC National Center for Health Statistics, approximately 11 percent of nursing home residents have pressure ulcers at any given time. Because they are almost entirely preventable with consistent repositioning and monitoring, their presence in a nursing home is a recognized indicator of deficient care.

How Prolonged Pressure Damages Tissue

When a person stays in the same position without being turned or repositioned, pressure compresses blood vessels over bony areas of the body. Within hours, restricted blood flow begins to kill skin cells. Without intervention, the damage moves inward from the skin surface into fat, muscle, and eventually bone.

Who Is at Highest Risk

Residents with limited mobility, cognitive impairment, diabetes, poor nutrition, or incontinence face the highest risk. California nursing homes are required to conduct individualized risk assessments for each resident on admission and update them regularly. When a facility identifies risk and then fails to act on it, preventable injuries follow.

The Four Stages of Bedsores

The staging system used by the Centers for Medicare and Medicaid Services classifies pressure injuries into four stages based on the depth of tissue damage. Each stage carries distinct medical requirements and, in the legal context, distinct significance for a neglect claim.

Stage 1: Surface Changes With No Open Wound

A Stage 1 pressure injury presents as persistent skin discoloration that does not blanch when pressed, often appearing red in lighter skin tones or darker in those with deeper pigmentation. The skin is intact but may feel warm, firm, or painful. Stage 1 is fully reversible with prompt intervention. A facility that identifies Stage 1 changes and fails to respond with repositioning, pressure-relief equipment, and documented skin monitoring is on notice of a developing wound and choosing not to act.

Stage 2: Partial Skin Loss

Stage 2 involves partial thickness skin loss, presenting as a shallow open wound with a red or pink wound bed, or as an intact or broken blister. The wound is now open and susceptible to infection. Proper wound care and enforced repositioning schedules are medically required at this stage. Stage 2 wounds that are ignored or poorly treated progress rapidly.

Stage 3: Full Thickness Skin Loss Into Fat Tissue

Stage 3 pressure ulcers involve full thickness loss of skin, exposing the subcutaneous fat layer beneath. Slough, which is dead white or yellow tissue, may be visible in the wound bed. The depth varies based on anatomical location, but the wound is serious. A Stage 3 ulcer developing in a nursing home is strong evidence of systemic failure in that resident's care plan.

Stage 4: Exposure of Muscle, Tendon, or Bone

Stage 4 pressure ulcers are the most severe category. They involve full thickness tissue loss exposing muscle, tendon, cartilage, or bone. These wounds create a life-threatening risk of osteomyelitis (bone infection) and sepsis. The Agency for Healthcare Research and Quality classifies Stage 3 and Stage 4 pressure ulcers among the most serious preventable harms in long-term care. The medical community refers to them as "never events," meaning they should not occur when proper care is provided. A Stage 4 ulcer on a nursing home resident is, in most cases, direct evidence of neglect.

Where Bedsores Form Most Often

Pressure injuries develop over bony areas of the body where tissue between skin and bone is thin:

  • Heels and ankles, from lying in bed without position changes
  • Tailbone and sacrum, from prolonged semi-reclined or seated positions
  • Hips, from side-lying without adequate pressure relief
  • Shoulder blades and elbows, from extended bed rest
  • Back of the head, particularly in immobile or sedated residents

Why Bedsores Develop in Nursing Homes

The root cause of most nursing home pressure ulcers is inadequate repositioning. Immobile residents must be turned at least every two hours in bed and repositioned approximately every 15 minutes while seated. These intervals represent the clinical standard, not a suggestion. Under California Health and Safety Code Section 1276.5, skilled nursing facilities must provide a minimum of 3.5 direct care service hours per resident per day. When a facility's staffing falls below that floor or staff are stretched too thin to execute repositioning schedules, bedsores are a predictable consequence.

Failure to Reposition

Repositioning schedules exist to prevent pressure ulcer formation. When a nursing home fails to document turns, or when care plan records show hours-long gaps between repositioning events, that documentation is direct evidence of neglect.

Inadequate Skin Assessment

California nursing homes are required to conduct regular skin assessments and record findings in each resident's medical chart. When a Stage 1 injury goes unrecorded and progresses to Stage 3 or Stage 4, the documentation gap itself tells the story of what happened.

Untreated Wound Infections

An open pressure wound is an infection risk. Proper wound care, dressing changes, and antibiotic treatment when clinically indicated are not optional. When a nursing home fails to treat a wound consistently, infection can reach the bloodstream and cause sepsis, which carries a high fatality rate in elderly patients.

California Law and Nursing Home Liability for Bedsores

California's Elder Abuse and Dependent Adult Civil Protection Act, Welfare and Institutions Code Section 15600 provides strong remedies for families whose loved ones suffer from nursing home neglect. Under Welfare and Institutions Code Section 15610.57, neglect includes failing to provide medical care, hygiene, and protection from health and safety hazards. Allowing a preventable pressure ulcer to form and progress is neglect under this definition. When a facility's conduct is reckless, oppressive, or malicious, the Act allows families to recover enhanced damages and attorney's fees in addition to compensation for injuries.

What Must Be Proven

A bedsore neglect claim under California law requires showing that the facility owed a duty of care to the resident, that it breached that duty through inadequate repositioning, skin assessment, or wound care, and that the breach caused the pressure ulcer and the resulting harm. Medical records, care plans, staffing logs, and skin assessment documentation are central to that case.

Damages Available to Families

Compensation in a bedsore neglect case can include medical expenses for wound care, hospitalization, and surgery; damages for pain and suffering; enhanced damages when reckless conduct is proven under the Elder Abuse Act; and wrongful death damages when a Stage 3 or Stage 4 ulcer or its complications cause death.

Evidence Used in Bedsore Cases

  • Medical records showing wound staging, treatment history, and documentation gaps
  • Care plan records showing whether repositioning schedules were ordered and followed
  • Staffing logs showing nurse-to-resident ratios during the relevant period
  • Timestamped photographs of the wound at each visible stage
  • CDPH citation history for the facility, searchable on the Cal Health Find portal
  • Expert testimony from wound care specialists on what proper care required

Frequently Asked Questions

Are all bedsores evidence of nursing home neglect?

Not every pressure ulcer is the result of neglect, because some residents develop wounds despite excellent care due to circulatory failure in the final stages of a terminal illness. However, a Stage 3 or Stage 4 ulcer that developed in a facility with documented repositioning failures, absent skin assessment records, or understaffing is strong evidence of a preventable injury. An attorney can review the specific facts and records to assess what happened.

What should I do if I discover a bedsore on a loved one during a visit?

Photograph the wound immediately before any cleaning or dressing is applied, and request the nursing home's incident report and current skin assessment documentation in writing. If the facility cannot show that the wound was identified, staged, and actively treated, contact the California Long-Term Care Ombudsman at (800) 231-4024 and consult an attorney before signing anything the facility asks you to review.

Can a family pursue a claim if their loved one has already passed away?

Yes. If a bedsore or its complications contributed to a resident's death, surviving family members can bring a wrongful death claim, and the estate's personal representative can bring a separate survival action to recover damages the resident would have been entitled to claim. Statute of limitations deadlines apply, so consulting an attorney as soon as possible after a loved one's death is important.
