Pressure Sores in Elderly Patients – Understanding the Issue

Pressure sores, or bedsores, occur when invalid patients spend long stretches in bed and are unable to relieve the pressure on parts of their body.
Pressure Sores in Elderly Patients

If someone you love resides in a nursing home or has an in-home caregiver, be on the lookout for one sure sign that they are not receiving the care they deserve.

Pressure sores.

Pressure sores, or bedsores, occur when immobile patients spend long stretches in bed and are unable to relieve the pressure on parts of their body that make contact with the bed. It happens most often in areas where the skin is close to the bone.

Where to Look for Pressure Sores

Some of the common spots for pressure sores in elderly, bedridden individuals include the following:

  • Hips
  • Elbows
  • Ankles
  • Heels
  • Back
  • Spine
  • Shoulder blades
  • Sides and back of the head

Pressure sores in elderly patients who spend a lot of time in wheelchairs are also common. Whenever someone spends a lot of time in one spot, bedsores are a risk.

What Causes Pressure Sores in Elderly Patients?

There are three primary causes of pressure sores:

  1. Friction
  2. Shear
  3. Sustained pressure

Each is discussed further in the following sections.


Friction occurs when the patient changes positions or moves from a bed to a wheelchair. The skin rubs against another surface, such as the bed sheet or clothing, and the other surface resists the applied motion.


Shear is another primary cause of pressure sores in elderly individuals. It is similar to friction, except the two surfaces are moving in opposite directions. Shear can damage tissue and blood vessels, and make the skin more susceptible to the third cause of pressure sores: sustained pressure.

Sustained Pressure

Sustained pressure occurs when an inactive patient’s skin and tissue become trapped between two hard surfaces:

  1. Bone, and
  2. A resting surface, such as a wheelchair or bed

The resulting pressure may be enough to prevent adequate blood flow from reaching the area. Without proper blood flow (and the oxygen and nutrients it carries), skin tissue can eventually wither and die.

How to Treat Pressure Sores in Elderly Patients

Bedsores can be prevented by encouraging patients to change positions, lay on different sides of their bodies, and move from a bed to a wheelchair. However, if it is too late, due to caregiver neglect or patient obstinacy, there are several ways to treat pressure sores.

  • Keep the wounds clean with cleaning solutions
  • A course of antibiotics
  • Reposition the patient often
  • Use specially designed pillows, mattresses, or cushions

The 4 Stages of Pressure Sores in Elderly Patients

Bedsores, if not treated immediately, can increase in seriousness through four stages:

  • Stage 1 – Skin is intact, but discolored and painful
  • Stage 2 – The wound opens, or looks like a pink blister filled with fluid
  • Stage 3 – Sores become deep and craterous; infection spreads
  • Stage 4 – The wound is so bad that bone, tendon, or muscle tissue becomes exposed

If your loved one is suffering from stage 3 or 4 bedsores while in the care of an in-home nurse, an elder care home, or even a relative, the odds are substantial that something is very wrong with the care the patient is receiving. It might be a good idea to change services or homes, and perhaps even to seek legal counsel on the patient’s behalf.

If you suspect a loved one has been injured, neglected or abused while in the care of a Southern California nursing home, assisted living facility or caretaker, or if you are the victim, it is important to contact Moran Law immediately to discuss your case.
