Patient/caregiver was educated on pathophysiology of pressure ulcer development as follows:

1. Pressure ulcers, also called bedsores, are injuries to skin and underlying tissue resulting from unrelieved and prolonged pressure on the skin.
2. Pressure ulcers often develop in individuals with history of prolonged bedrest, wheelchair bound status, and limited independence for ADL performance.
3. Bedsores develop secondary to the unrelieved pressure on the skin and the skin getting damaged between the dependent surface (bed/chair) and the underlying bone.
4. Pressure ulcers mostly develop on the skin over bony prominences, especially on the dependent parts of the body, such as, the elbows, shoulder blades, heels, ankles, hips, sacrum, and back of arms and legs resting against any surface for prolonged periods of time.
5. Depending on the extent and depth of skin injury, pressure ulcers are graded into stages 1 – 4, 1 being mild injury and 4 being extensive injury to the skin involved.
