Bed sores, also called pressure ulcers or pressure injuries, can develop quickly in older adults who spend much of the day in bed or a wheelchair. They are painful, can lead to serious infections, and are often preventable with the right daily routines. This guide explains how bed sores in elderly adults form, how to spot them early, and what families in Miami-Dade and Broward Counties can do at home.
When a sore does develop, physician-ordered wound care from a skilled home health team can help clean, dress, and monitor the wound while keeping your loved one’s doctor informed.
Home health care simply means skilled medical services delivered in the home when they are needed. It is provided with a physician’s orders and coordination, and it works alongside your loved one’s doctors rather than replacing them.
Key Takeaways
- Bed sores form when constant pressure, friction, or shear reduces blood flow to the skin.
- Bony areas like the sacrum, heels, and hips are the most common sites.
- Bed sores are classified into four stages, and early detection makes treatment simpler.
- Regular repositioning, skin care, good nutrition, and the right support surfaces are the foundation of prevention.
- Signs of infection or a worsening wound need prompt attention from the physician.
What Causes Bed Sores in Older Adults
A bed sore develops when steady pressure on the skin limits blood flow to the tissue underneath. Without enough oxygen and nutrients, skin and deeper tissue begin to break down. Pressure is the main cause, but two other forces contribute: friction, when skin rubs against sheets or clothing, and shear, when the skin stays in place while the body slides, such as when someone slips down in bed with the head raised.
Aging skin is thinner, drier, and less elastic, which makes it more fragile. Moisture from sweat or incontinence, poor nutrition, dehydration, and long periods of immobility weaken the skin further, so sores can form faster than many families expect.
Who Is Most at Risk and Where Sores Form
Anyone with limited mobility can develop a pressure injury, but some older adults face a higher risk:
- People who are bedbound or use a wheelchair most of the day
- Those recovering from surgery, a stroke, or a hospital stay
- Adults living with incontinence
- People with diabetes or poor circulation
- Those who are underweight, malnourished, or dehydrated
- People with reduced sensation or memory changes who may not notice discomfort or shift position
Sores usually form over bony areas where there is little padding. In bed, the most common sites are the sacrum and tailbone, heels, hips, shoulder blades, elbows, and the back of the head. In a wheelchair, pressure tends to concentrate on the buttocks, tailbone, and the backs of the legs and shoulders.

The 4 Stages of Bed Sores
Clinicians classify the stages of bed sores by how deeply the tissue is damaged. Recognizing the early stages gives families the best chance to stop a sore from getting worse.
| Stage | What It Looks Like | What It Means |
| Stage 1 | Intact skin with redness that doesn’t fade when pressed; may feel warm, firm, or painful | An early warning sign; relieving pressure right away is critical |
| Stage 2 | A shallow open sore or blister with a pink or red wound bed | The top layers of skin are damaged |
| Stage 3 | A deeper, crater-like wound that reaches the fat layer | Full-thickness skin loss that needs professional wound care |
| Stage 4 | A deep wound exposing muscle, tendon, or bone | Severe damage with a high risk of serious infection |
Some wounds are labeled unstageable when dead tissue covers the base, or a deep tissue injury when the skin is intact but discolored purple or maroon. These categories come from the National Pressure Injury Advisory Panel, whose definitions clinicians use to guide treatment. On darker skin, early redness can be harder to see, so changes in color, temperature, or firmness are important clues.
Daily Prevention at Home
Learning how to prevent bed sores in elderly loved ones comes down to a few consistent habits. Ask the physician or home health nurse to tailor these steps to your loved one’s needs.
Repositioning Schedules in Bed and Wheelchair
Changing position regularly is the most important way to relieve pressure. A common guideline is to help someone in bed change position at least every two hours. In a wheelchair, weight shifts are needed more often, about every 15 minutes for those who can do them independently, with full repositioning about every hour. Use pillows or foam wedges to keep bony areas from pressing against each other, keep the head of the bed at 30 degrees or lower when possible to reduce shear, and lift rather than drag your loved one when moving them.
Skin Care, Moisture, and Incontinence
Check the skin daily, paying close attention to bony areas, and look for redness, warmth, blisters, or broken skin. Keep skin clean and dry with a gentle cleanser, patting rather than rubbing. For incontinence, change briefs and bedding promptly, clean the skin soon after each episode, and use a barrier cream if recommended. Moisturize dry skin, but avoid massaging bony or reddened areas, which can cause more damage. Good nutrition matters too: adequate protein, calories, and hydration help skin stay strong and heal, so ask the physician whether a dietitian referral or supplement makes sense.
Mattresses, Cushions, and Support Surfaces
Specialized support surfaces spread weight more evenly and reduce pressure on vulnerable areas. Options include pressure-redistributing foam mattresses or overlays, alternating-pressure or air mattresses for people at higher risk, and wheelchair cushions made of foam, gel, or air. Avoid donut-shaped cushions, which can concentrate pressure and reduce blood flow. Heel protectors or a pillow under the calves can keep the heels off the mattress. The physician or home health team can recommend the right equipment; coverage for medical equipment varies by plan, so verify your benefits.
Signs of Infection and When to Call the Doctor
An infected pressure sore can become serious, so watch for changes and contact the physician promptly if you notice any of the following:
- Increased redness, warmth, or swelling around the wound
- Pus, cloudy drainage, or a foul odor
- New or worsening pain
- A wound that is growing larger or deeper
- Darkened or black tissue in the wound
- Fever or chills
- Sudden confusion or unusual weakness
Fever, chills, confusion, or a rapid heartbeat can be signs that infection has spread, which may require urgent care; if symptoms seem severe, call 911. Even without signs of infection, report any new open sore, or any reddened area that doesn’t improve after pressure is relieved, to the doctor.
How Skilled Nurses Treat Pressure Sores at Home
Bed sore treatment at home works best when it follows a physician-ordered plan and is guided by a skilled nurse. During home visits, a nurse can assess and measure the wound, clean it and apply the appropriate dressing, watch for signs of infection, and update the physician on how it is healing.
With physician-ordered skilled nursing at home, nurses also teach family caregivers how to reposition safely, protect the skin, manage incontinence, and recognize warning signs between visits. They coordinate with the doctor on pain management, nutrition support, and any needed equipment or therapy. Healing times vary from person to person, so ongoing monitoring matters. Medicare may cover home health wound care for eligible homebound patients when it is ordered by a physician; coverage varies by plan, so verify your benefits.
AI Summary
This guide covers bed sores in elderly adults, also called pressure ulcers or pressure injuries, and how families in Miami-Dade and Broward Counties can prevent and manage them at home. Bed sores form when pressure, friction, or shear reduces blood flow to the skin, most often over the sacrum, heels, and hips. They are classified into four stages, from red, intact skin to deep wounds exposing muscle or bone. Prevention relies on repositioning at least every two hours in bed, frequent weight shifts in a wheelchair, daily skin checks, moisture and incontinence care, good nutrition, and pressure-redistributing mattresses and cushions. Signs of infection need prompt physician attention. Home Advantage Home Health provides skilled, physician-coordinated wound care and nursing across Miami-Dade and Broward Counties.
