Plus Sized Pressure Care

In the current climate accessible care for all has never been so important.

In one US study the prevalence of obesity increased from 16.9% to 25.8% among newly admitted nursing home residents in just ten years (Cai, Rahman et al. 2013). Sadly, alongside increased body mass comes reduced mobility, increased difficulty for care workers when repositioning and a higher risk of having some secondary health issues, all risk factors for pressure ulcer development.

In the same study residents with moderate or severe obesity had, on average, 15.0% higher odds of having pressure ulcers as compared with non-obese residents in the same facility.

With these statistics in mind it’s easy to see why our plus sized patients need to be afforded the right care using the right equipment, which can come with challenges for care homes or for care in the community equipment providers.

Private homes and non-purpose-built nursing homes can have infrastructure issues that hinder plus sized care. In an acute care environment rooms for plus sized patients are recommended to be 17ft wide and 13.5ft long, not including space for furnishings (Muir 2009), quite a challenge to replicate in longer term care settings.

Secondly, many care providers simply do not keep in stock the equipment needed for those at the more extreme definitions of bariatric, or certainly do not have this equipment in quantity.

Finally, it can be a challenge to source all the required equipment simply and easily – a frustration when a new resident is arriving at a care home with specific needs, or a private home needs to be fitted out to allow a patient to be discharged from hospital.

At Harvest Healthcare we aim to relive the stress of sourcing and fitting plus sized equipment, leaving you to focus on providing the best quality care and support.  Our plus sized brochure contains our full range, making choosing what you need simple and easy, and our knowledgeable customer services and sales teams can talk you through any tricky situations. Our sister company Prism Medical can also support with ceiling track hoists, an excellent way to make use of smaller spaces.

The Harvest range includes beds, mattresses, hoists and bathroom equipment, all designed to make life easier for residents and for their carers and give everyone access to the love and support they deserve.

Warning Signs and Symptoms of Pressure Ulcers

Pressure ulcers often develop slowly but can develop in just a few hours with the right conditions.

Pressure ulcers are likely to develop faster when there is higher pressure on a smaller area, and more slowly when there is lower pressure over a wider area.

What are the Early Signs of Pressure Ulcer Development?

Early signs of pressure ulcer development include:

  • A change in the colour of the skin. People with pale skin are more likely to see red patches on the skin, and people with darker skin area more likely to see purple or blue patches.
  • Reddening of the skin that does NOT turn white when you press it. This is called a ‘non-blanching erythema’.
  • Any unusual changes in skin texture may be related to pressure damage. Common changes include skin feeling spongy or ‘boggy’.
  • A patch of skin that feels cooler or warmer to the touch than others.
  • A sore or itchy patch of skin.

Bedsores fall into one of several stages based on their depth, severity and other characteristics. The degree of skin and tissue damage ranges from red, unbroken skin to a deep injury involving muscle and bone. Skin showing these signs of pressure ulcer development may be referred to as ‘category one’.

See our related article for more information on the staging of pressure ulcers.

What are the Later Signs of Pressure Ulcer Development?

As pressure ulcers worsen, they may break the skin. Signs of worsening pressure ulcers include:

  • An open wound or
  • A deep wound that reaches the deeper layers of the skin.
  • A very deep wound that may reach the muscle and bone.

When should I get help for a Pressure Ulcer?

The NHS website says that if you’re in hospital or a care home, you should tell your healthcare team as soon as possible if you develop symptoms of a pressure ulcer as it will probably continue to get worse if nothing is done about it.

If you’re recovering from illness or surgery at home, or are caring for someone confined to bed or a wheelchair, contact your GP surgery if you think you or the person you’re caring for might have a pressure ulcer.

Get medical advice immediately if there is:

  • Red, swollen skin
  • Pus coming from the pressure ulcer or wound
  • Cold skin and a fast heartbeat
  • Severe or worsening pain
  • A high temperature (fever) of 38C (100.4F) or above

These symptoms could be a sign of a serious infection that needs to be treated as soon as possible.

Staging / Grading of Pressure Ulcers

Pressure ulcers vary in size and severity of the tissue affected, ranging from reddening of the skin to damage to muscle and underlying bone.

How are Pressure Ulcers Staged / Graded / Classified?

According to the international classification system pressure ulcers can be staged as one of six categories.

Superficial

Stage 1: Intact skin with persistent reddening, known as ‘non-blanching erythema’. For more information on non-blanching erythema, click here.

Stage 2: An abrasion or a blister can be seen, without bruising. There is some skin loss or damage affecting the top skin layers.

Superficial ulcers are more difficult to spot than deep ulcers. For information on the warning signs of pressure ulcer development click here.

Deep

Stage 3: Full thickness skin loss which can expose fat in areas where this exists. Damage is limited to the skin and fat layers.

Stage 4: Full thickness skin loss with damage to the underlying structures, such as tendons or bone, which may be exposed.

Other

Deep tissue injury: Tissue injury hidden under intact skin. These appear as deep bruises and can quickly deteriorate into a high-stage pressure ulcer. For more information on why deep tissue injuries occur, click here.

Unstageable Pressure Injury: Pressure ulcer with an undetermined level of tissue injury because the entire base of the wound is covered by slough tissue.

The grading of a pressure ulcer is a critical part of the process of caring for a person with pressure ulcers.

While treatment is tailored to the individual, as may factors can impact the development of a pressure injury, the grade of pressure sore is an important part of creating a treatment/management plan.

Shear and Friction in Pressure Ulcer Development

While the major factor in the development of pressure injury is pressure itself, shear forces also play a part.

What causes shear and friction?

When you move over a surface and the body remains in contact with it, the skin can be pulled along that surface. You can feel this ‘drag’ effect if you run your hand over something.

This ‘drag’ is caused by friction and leads to a difference in the direction of movement of the skin and the deeper tissues. This difference is called “shear” and is an important factor in pressure ulcer development.

How can shear forces lead to the development of a pressure ulcer?

Shear causes stretching and tearing of blood vessels which reduce blood flow increase blood pooling and can lead to cell damage.

Shearing stops or reduces blood flow more easily than pressure alone (for example, it is easier to cut off flow in a water hose by bending than by pinching it).

Although shear causes tissue damage slightly differently to pressure, the damage produced is the same as with pressure.

Importantly, it is difficult to create pressure without shear, and shear without pressure, so the two usually go hand-in-hand.

For information on how pressure leads to pressure injury, see our article How Pressure Ulcers Develop?

How can repeated friction cause a pressure ulcer?

As well as being a key element of making shear force, friction between the skin and the stationary surfaces such as bedclothes can result in the loss of the top layer of the skin (the stratum corneum).

Think about repeatedly rubbing your skin against a surface – after a time, the skin would start to become red and sore. This is due to friction.

This inflammation can lead to deeper injury or could be the initial damage needed to start pressure ulcer formation.

When there is a loss of the top skin layer, there is also a breach in the barrier against infection.

How can friction and shear be reduced?

There are several strategies to reduce shear and friction forces:

  • Use low-friction clothing such as Parafricta undergarments and socks to reduce friction on the vulnerable heel and pelvic areas. These can be especially useful for people who push themselves back up the bed using their heels, or who have involuntary leg movement, for example, those with Parkinson’s.
  • Use positioning aids such as slides sheets under the person’s body and feet and heels when repositioning to reduce the risk of friction and shear.
  • Use a profiling bed with an in-built knee break. When the person has been repositioned in bed, elevate the knee break first to prevent the person from sliding down the bed.

Risk Factors for Pressure Ulcer Development

Who is at Risk of Developing Pressure Ulcers?

The risk of developing a pressure ulcer is affected by many health and environment-associated factors.

In fact, more than 100 risk factors for pressure ulcers have been identified.

This means that anyone can get a pressure ulcer, although the following factors can make them more likely to develop:

  • Being elderly – older people are more likely to have mobility problems and may also have thin skin that is more easily damaged.
  • Being confined to bed or a chair with an acute illness, for example a urine infection, diarrhoea and vomiting, or after recent surgery.
  • Full or partial paralysis, reducing the ability to move independently.
  • Incontinence leading to wet and irritated skin.
  • Poor nutrition, which may be due to a lack of adequate nutrients or insufficient calories.
  • Medical conditions such as kidney disease or heart failure, or those that affect the blood supply, such as diabetes or peripheral arterial disease, or conditions that affect the ability to move independently, such as a stroke (CVA), multiple sclerosis (MS) or Parkinson’s disease.
  • History of previous pressure damage, where scar tissue may be present, as this will be less resilient than normal skin.
