Decubitus ulcers are common in debilitated patients, particularly the aged who have thinner skin and subcutaneous tissue that is more susceptible to compression injury.
Patients with limited mobility (from injury, sickness, or neurologic disorders, etc.), poor nutritional intake, conditions affecting perfusion and oxygenation of tissues (like diabetes, cardiovascular disease, heart failure, etc.), skin moisture due to incontinence, and advanced age are particularly vulnerable.
These ulcers are often multifactorial, making them difficult to prevent and even more difficult to heal in at-risk patients.
