How to Prevent Bed Sores in Bedridden Patients at Home
Bed sores can appear in hours and take months to heal — yet almost all are preventable. Here is the complete home routine for bed sore prevention.
Key takeaways
- Reposition the patient every 2 hours — this single habit prevents most bed sores.
- Check pressure points (hips, heels, tailbone, elbows, shoulders) daily for redness.
- Keep skin clean and dry, use a pressure-relief mattress, and maintain good nutrition and hydration.
What bed sores are and why they form
Bed sores (pressure ulcers) form when constant pressure on the skin — usually over a bony area — cuts off blood supply. The skin and tissue underneath begin to die. They can start in as little as two hours of unrelieved pressure, which is why immobile patients are at such high risk. The cornerstone of bed sore prevention is simple: never let pressure stay in one place for too long.
The 2-hour turning rule
Reposition the patient at least every two hours, day and night. Alternate between left side, back, and right side. Use pillows to support the new position and to keep knees and ankles from pressing against each other. A turning chart taped to the wall keeps everyone — family and caregivers — on schedule.
Daily skin checks: where to look
Inspect the skin at every position change, paying special attention to bony pressure points:
- Tailbone and lower back
- Hips and buttocks
- Heels and ankles
- Elbows and shoulder blades
- Back of the head and ears (for very thin patients)
The first warning sign is a patch of redness that does not fade when you press it. Treat that as a red alert — relieve all pressure from the area immediately and call a nurse.
Skin, surface, and nutrition
- Keep skin clean and dry. Sponge bathe daily, change soiled bedding at once, and use a barrier cream on at-risk skin. Moisture from sweat or incontinence accelerates sores.
- Use the right surface. A pressure-relief or air mattress redistributes weight. Avoid 'donut' cushions, which can make things worse.
- Reduce friction. Lift rather than drag the patient when moving them; dragging tears fragile skin.
- Feed for healing. Protein, vitamin C, zinc, and plenty of fluids keep skin resilient. See our diet tips for bedridden patients.
When to call a nurse
If you see broken skin, an open wound, foul smell, pus, or fever, do not treat it at home alone — an untreated sore can lead to deep infection and sepsis. A home nurse can stage the wound, dress it correctly, and set up a prevention plan.
