Kennedy Ulcer: What Is It And What You Need To Know

Tags :

Kennedy ulcer, also known as Kennedy terminal ulcer, is a specific type of pressure ulcer that manifests in terminally ill patients. Recognizing Kennedy ulcers is essential for providing appropriate care and managing symptoms effectively in terminally ill patients. Given their association with end-of-life care, proper understanding and management of Kennedy ulcers can enhance the quality of life for patients and ensure their comfort during this sensitive stage of life. Additionally, understanding why it’s termed "Kennedy ulcers" sheds light on their historical context and significance in wound care literature.

What Is Kennedy Ulcer?

Definition and Characteristics of Kennedy Ulcer

A Kennedy ulcer is a distinct type of pressure ulcer that primarily affects individuals in the terminal stages of illness or nearing the end of life. It is characterized by its sudden onset and rapid progression, often appearing as a sharply defined, irregularly shaped lesion with a dark maroon or purple hue. Kennedy ulcers typically develop on the sacral or coccygeal area but can also occur on other pressure points, such as the heels, hips, or elbows.

Clinical Presentation of Kennedy Ulcer

Kennedy ulcers are painful, non-blanchable lesions with surrounding tissue exhibiting signs of impending necrosis. Unlike traditional pressure ulcers, Kennedy ulcers may not exhibit the typical signs of tissue breakdown, such as erythema or inflammation. Instead, they often appear deep, crater-like wounds with minimal surrounding tissue trauma. Despite their distinct presentation, Kennedy ulcers share similarities with other pressure ulcers in their association with prolonged pressure, friction, and shear forces on vulnerable skin areas.

Background of Kennedy Ulcer's Naming

The term "Kennedy ulcer" originates from Dr. Patricia Kennedy, a renowned physician and pioneer in wound care. Dr. Kennedy was among the first to identify and describe this unique type of pressure ulcer in individuals nearing the end of life. Her extensive research and clinical observations led to the recognition of Kennedy ulcers as separate from conventional pressure ulcers. The name "Kennedy ulcer" was subsequently coined in honor of her contributions to understanding and managing this condition.

Contribution of Dr. Patricia Kennedy to Wound Care

Dr. Patricia Kennedy made significant contributions to the field of wound care through her innovative research, compassionate patient care, and advocacy for improved end-of-life management. Her work shed light on the pathophysiology, clinical presentation, and management strategies for Kennedy ulcers, providing healthcare professionals valuable insights into this often-overlooked aspect of palliative care. Dr. Kennedy's dedication to advancing wound care practices has left a lasting impact on the medical community. It continues to influence the treatment of patients with complex wound-related issues, including Kennedy ulcers.

What Causes Kennedy Ulcer?

Underlying Factors and Etiology

Kennedy ulcers, also referred to as Kennedy terminal ulcers, are a distinct type of pressure ulcer that predominantly occurs in individuals approaching the end of life. The pathophysiology of Kennedy ulcers is complex and multifactorial, involving various physiological and systemic changes associated with the terminal stages of illness. While the exact mechanisms underlying their development remain incompletely understood, several key factors contribute to the formation of Kennedy ulcers:

Diminished Tissue Perfusion: As individuals near the end of life, physiological changes, including decreased cardiac output and peripheral vascular resistance, can lead to compromised blood flow to the skin and underlying tissues. This reduction in tissue perfusion impairs oxygen and nutrient delivery to the skin, rendering it more susceptible to ischemic injury and breakdown.

Prolonged Immobility: Many terminally ill patients experience significant immobility due to weakness, fatigue, and declining functional status. Prolonged immobility exacerbates the risk of pressure ulcer development by subjecting vulnerable body areas to sustained pressure and shear forces, particularly over bony prominences.

Systemic Changes: The systemic effects of terminal illness, such as cachexia, malnutrition, dehydration, and metabolic disturbances, can further compromise tissue integrity and wound healing. These systemic factors contribute to the overall vulnerability of the skin and increase the likelihood of tissue breakdown.

Risk Factors Associated with Kennedy Ulcer Development

Several risk factors are commonly associated with the development of Kennedy ulcers in individuals nearing the end of life:

Prolonged Immobility: Immobility from advanced illness or debilitation significantly increases the risk of pressure ulcer formation. Patients who are bedridden or confined to a chair for extended periods are particularly susceptible to developing Kennedy ulcers.

Reduced Tissue Perfusion: Conditions that impair vascular perfusion, such as cardiovascular disease, peripheral artery disease, or hypotension, contribute to tissue ischemia and increase the susceptibility to pressure ulcer development.

Nutritional Deficits: Malnutrition, cachexia, and dehydration are common in individuals with advanced illness and can compromise tissue health and wound healing. Poor nutritional status diminishes the body's ability to repair and regenerate damaged tissue, predisposing patients to Kennedy ulcer formation.

Comorbidities: Patients with underlying medical conditions such as cancer, heart failure, renal failure, or chronic obstructive pulmonary disease (COPD) are at higher risk of developing Kennedy ulcers due to the systemic effects of these diseases on tissue integrity and healing capacity.

Altered Sensory Perception: Neuropathies, cognitive impairment, or altered mental status can impair sensory perception and diminish the ability to detect discomfort or pain associated with prolonged pressure, leading to delayed recognition and intervention for pressure ulcers.

Limited Access to Preventive Measures: Patients receiving end-of-life care in hospice, palliative care, or long-term care settings may have limited access to preventive interventions such as repositioning, support surfaces, and specialized equipment due to their clinical condition or care environment constraints. This lack of preventive measures increases the risk of pressure ulcer development in this population.

Understanding these underlying factors and risk factors associated with Kennedy ulcer development is crucial for implementing effective preventive strategies and providing optimal wound care management in palliative and end-of-life settings.

How Can You Tell If You Have A Kennedy Ulcer?

Signs and Symptoms

Kennedy ulcers typically present as distinctive wounds characterized by specific clinical features. While individual presentations may vary, common signs and symptoms of Kennedy ulcers include:

Location: Kennedy ulcers primarily develop in regions with prominent bony prominences, such as the sacrum, coccyx, heels, and hips. These areas are subjected to prolonged pressure and shear forces, increasing the risk of tissue breakdown.

Appearance: Kennedy ulcers often exhibit a characteristic appearance, with irregularly shaped, well-defined borders and an underlying yellowish or brownish discoloration. The wound bed may appear necrotic, with slough or eschar present, indicating tissue ischemia and breakdown.

Pain: Kennedy ulcers may be accompanied by varying degrees of pain or discomfort, although some patients may experience minimal or no pain due to altered sensory perception or advanced illness.

Wound Exudate: Kennedy ulcers typically produce minimal to moderate serosanguinous or seropurulent exudate. Purulent drainage or foul odor may indicate secondary infection and warrant further evaluation.

Diagnostic Procedures and Evaluation

Diagnosis of Kennedy ulcers involves a comprehensive assessment of the patient's clinical history, physical examination findings, and wound characteristics. Diagnostic procedures and evaluation techniques may include:

Clinical Assessment: Healthcare providers conduct a thorough examination of the wound, including its location, size, depth, and surrounding tissue condition. Visual inspection and palpation help identify characteristic features of Kennedy ulcers and distinguish them from other types of pressure ulcers or skin lesions.

Wound Measurement: Accurate measurement of the ulcer's dimensions, including length, width, and depth, provides valuable information for tracking wound progression and guiding treatment decisions.

Tissue Assessment: Evaluation of the wound bed and surrounding tissue helps assess tissue viability, necrosis or eschar, and signs of infection. Tissue sampling or biopsy may be performed to confirm the diagnosis and rule out other underlying conditions.

Imaging Studies: In some cases, imaging modalities such as ultrasound, magnetic resonance imaging (MRI), or computed tomography (CT) scans may be utilized to assess the extent of tissue involvement, identify underlying bony pathology, or evaluate for complications such as deep tissue injury or osteomyelitis.

Prompt and accurate diagnosis of Kennedy ulcers is essential for initiating appropriate wound care interventions and preventing further tissue damage or complications. Collaborative interdisciplinary care involving wound care specialists, nurses, physicians, and other healthcare professionals is critical for optimizing patient outcomes and providing comprehensive management of Kennedy ulcers.

Kennedy Ulcer Treatments

Medical Interventions and Management Strategies

Pain Management: Addressing pain associated with Kennedy ulcers is a crucial aspect of treatment. Analgesic medications, topical agents, nerve blocks, or complementary therapies may be utilized to alleviate discomfort and improve patient comfort.

Pressure Redistribution: Implementing pressure-relieving strategies is essential to prevent further tissue damage and promote wound healing. This may involve specialized support surfaces, such as pressure-reducing mattresses, cushions, or heel-offloading devices, to minimize pressure and shear forces on vulnerable areas.

Infection Control: Managing infection is paramount in Kennedy ulcer management. Antibiotic therapy, wound debridement, and topical antimicrobial agents may be prescribed to address bacterial colonization or secondary infection and promote wound healing.

Nutritional Support: Optimizing nutritional status is vital for supporting tissue repair and regeneration. Patients with Kennedy ulcers may benefit from nutritional assessment and supplementation, including adequate protein intake, vitamin supplementation, and hydration to facilitate wound healing.

Wound Care Approaches and Best Practices

Wound Debridement: Removal of necrotic tissue, slough, or eschar is essential for promoting wound healing and preventing infection. Depending on the wound characteristics and the clinician's expertise, debridement techniques may include sharp, enzymatic, autolytic, or surgical debridement.

Moist Wound Healing: Maintaining a moist wound environment supports cellular proliferation, angiogenesis, and granulation tissue formation. Moist dressings, hydrogels, hydrocolloids, or foam dressings may provide optimal wound moisture and facilitate healing.

Wound Dressings: The selection of appropriate wound dressings plays a critical role in Kennedy ulcer management. Dressings should promote moisture balance, protect the wound bed, and minimize trauma to surrounding tissue. Depending on wound characteristics and clinician preference, silicone dressings, foam dressings, alginates, or composite dressings may be used.


Comprehending Kennedy ulcers is paramount for healthcare providers engaged in wound care. These ulcers, named after Dr. Patricia Kennedy, pose distinctive challenges due to their aggressive nature and link to terminal illness. By discerning Kennedy ulcers from other pressure injuries and implementing suitable treatment approaches—such as pain management, pressure redistribution, infection control, and advanced wound care methods—clinicians can enhance patient outcomes and elevate their quality of life. Furthermore, ongoing research and interdisciplinary cooperation are vital for advancing our comprehension of Kennedy ulcers and refining treatment options for individuals grappling with these complex wounds.
