Pressure ulcers, also known as bedsores or pressure sores, are closely linked to increased mortality in aging populations due to a combination of physiological, medical, and care-related factors. These ulcers develop when prolonged pressure on the skin and underlying tissues reduces blood flow, causing tissue damage and necrosis. In elderly individuals, this process is more likely and more dangerous because of several interconnected reasons.
First, aging skin is thinner, less elastic, and more fragile, making it more susceptible to injury from pressure and shear forces. The natural decline in skin integrity means that even minor pressure can lead to ulcer formation. Additionally, older adults often have reduced mobility due to chronic illnesses, neurological conditions, or frailty, which increases the duration of pressure on certain body parts, especially bony prominences like the sacrum, heels, and hips. Immobility is a primary risk factor for pressure ulcers because it prevents the natural shifting of weight that relieves pressure and maintains healthy blood flow.
Second, aging populations frequently have multiple comorbidities such as diabetes, cardiovascular disease, and malnutrition, which impair wound healing and immune response. Diabetes, for example, can cause peripheral neuropathy and poor circulation, reducing sensation and the ability to detect early signs of pressure damage. Malnutrition, common in elderly patients due to decreased appetite or difficulty eating, deprives the body of essential nutrients needed for tissue repair and immune function. Cardiovascular problems further compromise blood supply to tissues, exacerbating the risk and severity of ulcers.
Third, pressure ulcers themselves can lead to serious complications that increase mortality risk. Once an ulcer forms, it can become a portal for infection. Local infections can progress to cellulitis, abscess formation, or osteomyelitis (bone infection). In severe cases, bacteria can enter the bloodstream, causing sepsis, a life-threatening systemic inflammatory response. Elderly patients are particularly vulnerable to these infections because of weakened immune systems and slower healing processes. The presence of chronic wounds also often leads to prolonged hospital stays, increased healthcare interventions, and a higher likelihood of exposure to hospital-acquired infections.
Moreover, pressure ulcers are associated with significant pain and psychological distress, including anxiety and depression, which can negatively affect overall health and recovery. Chronic pain and emotional burden may reduce an elderly person’s motivation to participate in rehabilitation or self-care, further worsening their condition.
In healthcare settings, inadequate prevention and management of pressure ulcers contribute to their development and progression. Factors such as understaffing, insufficient training, and failure to implement regular repositioning or use pressure-relieving devices can lead to neglect of at-risk patients. When pressure ulcers are not promptly identified and treated, they worsen, increasing the risk of complications and death.
The link between pressure ulcers and mortality in aging populations is therefore multifactorial: fragile skin and reduced mobility increase ulcer risk; comorbidities and poor nutrition impair healing; infections and systemic complications from ulcers raise mortality; and psychological impacts further degrade health. Preventing pressure ulcers through attentive care, proper nutrition, regular repositioning, and early treatment is critical to reducing mortality and improving quality of life for elderly individuals.
