Pressure Ulcers: Understanding and Prevention

Pressure ulcers commonly referred to as bedsores or pressure sores, are areas of damaged skin and underlying tissue that result from prolonged pressure on the skin. These painful wounds typically develop on parts of the body that bear weight, such as the heels, hips, elbows, and lower back. Pressure ulcers can range in severity from superficial red marks to deep, open wounds that expose muscle or bone, significantly impacting a person’s quality of life and, in severe cases, leading to life-threatening infections.

Preventing pressure ulcers is a major concern in healthcare settings, especially for patients with reduced mobility, such as those in hospitals, care homes, or living with long-term illnesses. While these ulcers can be challenging to treat, prevention strategies are well-documented and critical to reducing their occurrence. In this article, we will explore what pressure ulcers are, how they develop, who is at risk, and the most effective prevention methods backed by research.

What Causes Pressure Ulcers?

Pressure ulcers form when prolonged pressure on the skin impairs blood flow to the area, depriving tissues of oxygen and nutrients. This sustained pressure can result in cell death and tissue damage. Several factors contribute to pressure ulcer development, including:

  • Pressure: When the skin and tissues are compressed between a hard surface (such as a bed or wheelchair) and bone, blood flow is restricted, leading to tissue damage.
  • Shear: This occurs when the skin moves in one direction, while the underlying bones move in another. Shear forces are common in bedridden individuals when they are moved inappropriately or slide down a bed.
  • Friction: Repeated rubbing of the skin against another surface can cause superficial damage, weakening the skin’s ability to resist pressure.
  • Moisture: Excessive moisture from sweat, urine, or wound exudate can soften the skin, making it more susceptible to pressure ulcers.

Who is at Risk?

While anyone can develop a pressure ulcer under certain conditions, certain groups of people are more vulnerable. These include:

  • Individuals with limited mobility: People confined to beds or wheelchairs, such as those recovering from surgery or with chronic conditions, are at high risk. Without regular repositioning, the pressure on specific body areas can become prolonged and lead to ulcers.
  • Elderly patients: As people age, skin becomes thinner and less elastic, making it more susceptible to damage. Reduced circulation and slower healing processes also increase the likelihood of pressure ulcer development in older adults.
  • People with impaired sensation: Those with conditions that affect nerve function, such as diabetes or spinal cord injuries, may not feel discomfort in areas under prolonged pressure and therefore don’t shift their position often enough to prevent ulcers.
  • Malnourished individuals: Poor nutrition weakens the skin and reduces the body’s ability to repair damaged tissues, making it more difficult to prevent or heal pressure ulcers.

The Stages of Pressure Ulcers

Pressure ulcers are classified into four main stages, depending on their severity:

  • Stage 1: The skin is intact but may appear red and does not blanch when pressed. It may feel warmer or cooler than the surrounding skin, and the person may experience pain or itching.
  • Stage 2: The skin breaks open, creating a shallow ulcer or blister. The area may be tender and painful.
  • Stage 3: The ulcer becomes a deep wound, extending into the fat tissue. It may resemble a crater and can be accompanied by dead tissue (eschar) or infection.
  • Stage 4: The most severe form, where the ulcer extends through the skin and fat into the muscle or bone. There is a high risk of serious infection at this stage.

Prevention of Pressure Ulcers

Preventing pressure ulcers requires a proactive approach, especially for individuals at high risk. Prevention strategies focus on reducing pressure, maintaining skin integrity, and addressing factors like moisture and nutrition.

1. Regular Repositioning

Frequent repositioning is one of the most effective ways to prevent pressure ulcers. For bedridden individuals, this typically means shifting positions every two hours, while wheelchair users should aim to relieve pressure every 15-30 minutes.

  • For bed-bound individuals: It is crucial to alternate between different positions such as supine (lying on the back), lateral (lying on the side), and prone (lying on the stomach) to distribute pressure more evenly across the body.
  • For wheelchair users: Individuals should shift their weight regularly by tilting or leaning forward to alleviate pressure on their back and buttocks.

2. Specialised Support Surfaces

Pressure-relieving surfaces, such as specialised mattresses, cushions, and overlays, play a key role in pressure ulcer prevention. These products are designed to reduce pressure on vulnerable areas by redistributing body weight more evenly.

  • Air-filled mattresses: These mattresses are adjustable to allow varying levels of pressure relief and can be particularly beneficial for people at high risk of developing ulcers.
  • Gel, air and foam cushions: These can be used in wheelchairs or beds to provide extra support for areas like the heels and sacrum.

3. Skin Care and Hygiene

Maintaining good skin hygiene is essential to prevent pressure ulcers. Moisture from sweat, urine, or other sources can break down the skin, making it more susceptible to damage. Here are a few key practices:

  • Keep the skin dry and clean: Regular cleaning with mild soap and water, followed by gentle drying, is crucial. Special attention should be paid to skin folds or areas prone to moisture buildup.
  • Moisturise dry skin: Dry skin is more prone to cracking, which increases the risk of ulcers. Use a moisturiser regularly to keep the skin supple.
  • Use barrier creams: In areas prone to moisture exposure, such as the buttocks or perineum, barrier creams can protect the skin by forming a protective layer.

4. Nutritional Support

Proper nutrition is crucial for maintaining healthy skin and promoting healing. Malnutrition weakens the body’s defences, making it harder to prevent and heal pressure ulcers. Diets rich in protein, vitamins (particularly vitamins C and E), and minerals like zinc and copper are essential.

For individuals at risk of pressure ulcers, consulting with a dietitian can ensure they receive adequate nutrients tailored to their specific needs. In cases where eating sufficient food is difficult, supplements or fortified meals may be recommended.

5. Education and Training

Ensuring that both caregivers and patients are educated about the risks and prevention of pressure ulcers is essential. Caregivers should be trained to reposition patients correctly, use pressure-relieving devices effectively, and monitor skin conditions regularly. Patients themselves can also play a role in prevention by being vigilant about early signs of pressure ulcers and participating in their own care whenever possible.

Research on Pressure Ulcer Prevention

There has been a wealth of research conducted on pressure ulcer prevention, given the high cost and significant morbidity associated with these wounds. Below are some of the key findings from recent studies:

1. Repositioning Frequency

Research supports the idea that frequent repositioning, especially in high-risk patients, significantly reduces the likelihood of pressure ulcer formation. A review from the Cochrane Library highlighted the importance of repositioning every 2 to 3 hours in reducing pressure ulcer incidence in various healthcare settings.

2. Effectiveness of Pressure-Relieving Devices

A Cochrane review assessed the effectiveness of different pressure-relieving devices, such as specialised mattresses, cushions, and overlays. The study found that air-filled and foam mattresses significantly reduced the risk of pressure ulcers when compared to standard hospital mattresses.

3. Nutritional Interventions

Nutritional support plays a crucial role in preventing pressure ulcers. A study published in the Journal of Clinical Nutrition found that protein supplementation and adequate caloric intake in at-risk patients reduced the occurrence of pressure ulcers by promoting skin integrity and healing.

4. Use of Skin Moisturisers and Barrier Creams

In a study published by Advances in Skin and Wound Care, regular use of moisturisers and barrier creams, particularly in areas prone to moisture exposure, significantly reduced the incidence of stage 1 and 2 pressure ulcers by maintaining skin integrity.

Conclusion

Pressure ulcers are a common and potentially serious issue for individuals with limited mobility. However, with proper prevention strategies, such as regular repositioning, the use of pressure-relieving devices, good skin care, and appropriate nutrition, the risk of developing these painful sores can be significantly reduced.

Research continues to support these prevention methods, and with ongoing education and the implementation of best practices, healthcare professionals and caregivers can dramatically improve patient outcomes and quality of life.

For those in the healthcare industry, from physiotherapists and podiatrists to doctors and orthotists, understanding the risks and prevention of pressure ulcers is critical. With continued advancements in pressure ulcer research, there are new opportunities to further reduce the incidence of this challenging condition and enhance patient care.
