Tissue susceptibility may be increased in the presence of maceration and by friction as well as shear forces.Chronic conditions, especially immobility and decreased tissue perfusion, increase the risk of pressure ulcers.Most pressure ulcers develop over bony prominences, most commonly the sacrum, heels, and trochanteric areas.Most pressure ulcers develop in acute hospitals; the risk is greatest in orthopedic and ICU patients.There are different stages and classifications of pressure ulcers. Pressure ulcers are classified as stage 1 to 4 depending on depth and severity of the wound.Pressure ulcers do not necessarily progress from stage 1 to 4.Treatment options differ depending on the type as well as stage of the wound and are often difficult to heal.Pressure ulcers have a significant impact on the quality of life of a patient as well as caregivers.Pressure ulcers have a significant cost to the health care system and have been associated with increased mortality rates in both acute and long-term care settings.
