Preventing pressure ulcers in bedbound dementia patients means relieving pressure often, keeping skin clean and dry, and checking pressure areas each day. Pressure ulcers, also called bedsores, are skin and tissue injuries caused by prolonged pressure, especially over bony areas. Caregivers combine frequent small shifts, pressure-redistributing mattresses or cushions, adequate food and fluids, and professional advice on safe turning. This bundle approach fits late-stage dementia care, when a person may spend most time in bed or a chair.

Why dementia increases risk
Dementia itself raises concern because immobility, sensory loss, poor nutrition, and inability to reposition without help all increase pressure damage. NICE lists significant cognitive impairment such as dementia as a trigger for documented risk assessment on admission to secondary care or care homes, described in NICE recommendations.
Late-stage Alzheimer's often leaves the person bedridden or chair-bound, which strains skin and joints. The Alzheimer's Association explains that prolonged pressure can cause skin breakdown, pressure sores, and joint stiffening, as detailed in late-stage caregiving guidance.
Which spots need daily inspection
Check areas that bear weight in bed or a chair, such as heels, hips, buttocks, elbows, shoulders, and the back of the head. Look for intact skin, redness that does not fade when pressed, and changes in heat, firmness, or moisture.
NICE advises trained professionals to assess these pressure areas for non-blanchable colour change, including in darker skin tones, plus variation linked to incontinence, swelling, or dry skin. Family caregivers can support this process by reporting new redness, pain response, blisters, or broken skin promptly.
How often should position change
Shift weight often to let blood reach compressed skin. The Alzheimer's Association advises changing position at least every two hours and using pillows to keep arms and legs aligned and supported.
No single schedule fits every person. Cochrane found no clear evidence that one repositioning frequency or position prevents sores better than another in hospitals or care homes, summarized in the Cochrane evidence summary. Pair regular small shifts with a pressure-redistributing mattress or cushion, and ask a nurse or therapist about safe lifting and turning technique.
How to protect skin, heels and nutrition
Keep skin clean, dry, and moisturized as needed, and manage incontinence quickly to limit moisture damage. Consider barrier products for high moisture risk, and agree a personal heel-offloading plan with the person and carers where needed.
Support healing and prevention with enough food, fluids, and hydration. Effective hospital prevention combines risk and skin checks, support-surface review, nutritional screening, moisture control, and regular repositioning. For home care, that means daily inspection, clean dry bedding, adequate drinks and meals, and early professional help for new marks.
