The appearance of a Kennedy Ulcer (KU), sometimes called a Kennedy Terminal Ulcer, is often associated with the final stage of life. This specific skin change signals a profound internal shift in the body of a person with a terminal illness. Its sudden development frequently prompts families and caregivers to seek clarity regarding the remaining time a loved one may have. This article provides an understanding of the nature of the Kennedy Ulcer and the typical timeline associated with its diagnosis.
Defining the Kennedy Ulcer
The Kennedy Ulcer is a skin wound distinguished from common pressure injuries, or bedsores, by its rapid onset and underlying cause. Nurse Karen Lou Kennedy-Evans first described it in 1989, noting its occurrence in patients nearing the end of life. Unlike typical pressure ulcers that develop over days or weeks, a Kennedy Ulcer can appear and progress dramatically within hours.
The wound most often appears on the sacrum (above the tailbone) but can also be found on other bony prominences. Its appearance is unique, often resembling a pear, butterfly, or horseshoe shape. Discoloration ranges from red or purple to dark black or yellow, often resembling a deep bruise that quickly deteriorates.
The Underlying Cause: Skin Failure
The development of a Kennedy Ulcer is not attributed to a lack of movement or localized neglect, but rather to a systemic physiological process known as “Skin Failure.” This describes the breakdown of the skin as an organ system during the end stages of a progressive, life-limiting illness. This inability to maintain skin integrity signals a widespread internal decline.
During the dying process, the body shunts blood and nutrients away from peripheral areas to concentrate resources on sustaining vital organs, such as the heart and brain. This poor tissue perfusion, or hypoperfusion, starves the skin of the oxygen and nutrition needed for repair. Consequently, the skin becomes highly vulnerable to injury, even from minimal pressure. The Kennedy Ulcer is viewed as an outward symptom of multi-organ system failure, rather than a preventable wound.
Addressing Prognosis and Longevity
The appearance of a Kennedy Ulcer is considered a sign of impending death, making it a powerful prognostic indicator. The typical survival window following diagnosis is short, often measured in days to a few weeks, reflecting the advanced state of the underlying disease. Some patients are noted to be in the final two weeks of life when the ulcer appears.
The specific timeline is variable and depends heavily on the ulcer’s presentation. The most rapidly progressing form, sometimes called the “3:30 syndrome,” often precedes death by less than 24 hours. A more common presentation may precede death by a few days up to several weeks. Prognosis is influenced by the severity of existing comorbidities, nutritional status, and the extent of systemic organ failure.
Care and Comfort Management
Once a Kennedy Ulcer is identified, the focus of care shifts from curative treatment to palliative management, prioritizing the patient’s comfort and dignity. The goal is to manage symptoms, as the body typically lacks the resources to heal the wound. Pain management is a primary objective, often involving pressure-relieving dressings and support surfaces to minimize discomfort.
Caregivers also focus on controlling symptoms like wound odor, which can be managed with specialized charcoal-infused dressings. Less frequent repositioning may be utilized for patients with a very short prognosis, as the discomfort of turning may outweigh the benefit of pressure relief. The care team provides emotional support and counseling to families, helping them understand that the ulcer is an unavoidable part of the dying process, not a sign of neglect.
