Handout – Pressure ulcer prevention
Suitable for care homes, nursing homes and hospitals.
What is a pressure ulcer?
A pressure ulcer is an area of flesh or tissue that is squeezed between a hard surface and a bony
prominence (such as a hip bone, heel or sacral bone above the buttocks). As the flesh is tightly
squeezed, the blood cannot reach the tissues and this causes a pressure injury (non-broken skin but
painful and red). Eventually, the tissues will die and turn black. This is a pressure ulcer. However, the
injury can easily be avoided with appropriate care.
Everyone has, at some point in their life, experienced the feeling of a pressure injury. Sit in a cinema
or theatre seat for two hours and you begin to feel very uncomfortable and begin to wriggle. If you are
enjoying the show and are engrossed in the content, you may not notice the discomfort until you
move. Then the discomfort becomes very noticeable. Imagine you are someone who can never move
and then you understand how important repositioning someone can be.
How do we know if a pressure injury is developing?
When blood is prevented from reaching the tissue for some time, the area becomes inflamed and
bright red. This is the very first sign that a pressure injury is developing. If a carer notes redness and
acts immediately, a pressure ulcer need never develop. In fact, the carer is the most important person
in the prevention of pressure injuries in clients.
How do we prevent pressure injury?
There are two main ways to prevent pressure injury which would ensure that a pressure ulcer does
not open the client to infection and potential death: repositioning and equipment.
This is a very simple method of pressure ulcer prevention and was discovered in the First World War
when orderlies were employed to care for the injured soldiers. They would pass from bed to bed,
washing and repositioning the soldiers, and they found it took two hours to go from bed one, around
the Nightingale ward, and back to bed one. They noted that this actually prevented pressure ulcers
from occurring. Today we realise that these were relatively healthy young men, and less likely to
develop pressure injury or ulcers. Our clients are generally elderly and more prone to tissue damage.
Therefore, we now recommend that the skin over bony prominences (heels, sacral area, hips etc.) is
examined regularly, and at least daily, for signs of redness. If redness is apparent, this tells the carer
that they must reposition more often. If there is no redness, then the repositioning time can be
There are all kinds of mattresses, from memory foam that creates a 'well' in the foam that is in the
shape of the body and redistributes the pressures away from the bony area, to mattresses that have
an inflation and deflation of air. Selecting the equipment, which should include cushions that are the
same quality as the mattress, is a simple process.
Are carers accountable for any pressure injury?
The answer to this is that carers do not have a professional body that will hold them accountable.
However, as a carer, they have a duty of care to the client. If they fail in that duty of care and cause
an unnecessary injury to the client (such as a pressure ulcer) then they may be held to account and
this can be through a Coroner’s Inquest or even a Court of Law.

Can a client die from pressure injury?
A pressure injury is unlikely to cause death, whereas a pressure ulcer is very likely to cause death. So
the answer to this is, yes, a client can die from a pressure ulcer which follows the original injury to the
skin. A researcher (Baxter, C. R. (1994), ‘Immunologic reactions in chronic wounds’, American
Journal of Surgery, 167:12S–14S) found that 67% of patients with a pressure ulcer who were
hospitalised would die compared with 15% of at-risk patients without pressure ulcers.
A pressure ulcer can create a poison that travels around the body and damages organs such as
kidneys. The client is often frail and the poison will lead to death. This is unacceptable as 95% of
pressure injuries are totally avoidable.
How many people develop pressure ulcers?
The NHS (http://www.nhs.uk/conditions/Pressure-ulcers/Pages/Introduction.aspx) estimates that just
under half a million people in the UK will develop at least one pressure ulcer in any given year. This is
usually people with an underlying health condition. For example, around 1 in 20 people who are
admitted to hospital with an acute (sudden) illness will develop a pressure ulcer.
How can I find out more about pressure ulcers and their prevention?
There are several excellent websites that any person caring for a client at risk of pressure injury
should be familiar with:
National Institute for Clinical Excellence:
Institute for Healthcare Improvement:
Royal College of Nursing:
These websites will provide you with a more in-depth description of pressure ulcers and how to
prevent them.
Pressure ulcers are preventable and there are different types of equipment that will promote the
health of the skin and prevent the pressure injury that can eventually lead to death.
