Pressure sores in the elderly: how to prevent them and how to care for the skin

When a parent or grandparent begins spending a great deal of time in bed or in an armchair, many families focus on administering medication correctly and ensuring general comfort, often overlooking a silent but extremely serious risk: pressure sores. These skin lesions can develop quickly — in just a few hours of constant pressure — and can progress from simple redness to deep wounds requiring emergency medical intervention.

For many carers, awareness comes too late, when the elderly person's skin already shows visible signs of deterioration. The reality is that pressure sores are far easier to prevent than to treat, and with a few simple gestures incorporated into the daily routine, you can protect your loved one's skin and ensure a much better quality of life.

In this article, we explain everything you need to know about pressure sores: how they develop, how to recognise them early, what practical methods you can apply at home, and when it is time to seek urgent specialist care. Whether you are caring for an elderly person at home or simply want to better understand their needs, this information will be of great help to you.

What pressure sores are and why they occur in elderly people

Pressure sores, also known as decubitus ulcers or pressure ulcers, are injuries to the skin and underlying tissues that occur when an area of the body is subjected to constant pressure over a prolonged period. In elderly people — particularly those confined to bed or a wheelchair — the risk is significantly higher due to skin fragility and reduced blood circulation.

The mechanism by which they develop is relatively straightforward, but the consequences can be serious. When the skin and soft tissues are compressed between bone and a hard surface (a mattress or armchair), blood flow to that area is dramatically reduced. Without sufficient oxygen and nutrients, cells begin to die and the skin deteriorates. The process can begin in as little as two to three hours of uninterrupted pressure — more quickly than many carers realise.

Why elderly people are more vulnerable

With age, skin becomes thinner, drier, and less elastic, losing its ability to withstand friction and pressure. Elderly people often have other conditions that increase the risk further:

• Poor blood circulation, worsened by diabetes or cardiovascular disease
• Weight loss and reduced fatty tissue that would otherwise protect the bones
• Urinary or faecal incontinence, which keeps the skin moist
• Reduced sensitivity, particularly in cases of neuropathy, meaning the elderly person may not feel discomfort
• Malnutrition or dehydration, which affects skin quality

Risk areas and contributing factors

Not all parts of the body are equally prone to developing pressure sores. There are critical areas where bone is close to the skin's surface and where pressure is most intense. Knowing these areas allows you to be far more attentive during daily care.

The most vulnerable areas of the body

For people lying on their back, the most vulnerable areas are:

• The sacral region (base of the spine) — the most common location
• The heels and ankles
• The shoulder blades and elbows
• The back of the head

If the elderly person lies on their side, the risk shifts to the hips, knees, and outer ankles. For those who spend time in an armchair or wheelchair, the buttock area and coccyx are most affected.

Factors that accelerate their development

Beyond pressure itself, several factors can trigger or worsen pressure sores:

1. Constant moisture — perspiration, urine, or faeces keeps the skin macerated and fragile
2. Friction and shearing forces — when an elderly person is dragged across a sheet rather than lifted, the skin tears
3. Dehydration — dry skin cracks more easily
4. Malnutrition — a lack of proteins and vitamins slows healing and weakens the skin
5. Complete immobility — the inability to change position independently

Practical methods for daily prevention

The good news is that most pressure sores can be prevented through simple, consistent measures that are accessible to any family. You do not need expensive equipment or advanced medical knowledge — only attentiveness, discipline, and a few basic techniques.

Repositioning — the golden rule

This is the most effective prevention method. Elderly people confined to bed must be repositioned every two hours, day and night. Yes, this may seem exhausting, but it is absolutely essential. Alternate positions: on the back, on the left side, on the right side, and occasionally on the stomach if their health permits.

For those in a wheelchair or armchair, pressure must be relieved every 15 to 30 minutes. If the elderly person is able, encourage them to lift themselves slightly or lean to one side for a few seconds. If they cannot, help them shift their position a little, or use cushions to redistribute pressure.

Using specialist mattresses and cushions

Investing in a pressure-relief mattress can make an enormous difference. There are several types available:

• Memory foam mattresses that mould to the body
• Alternating air cell mattresses that automatically vary pressure points
• Gel surfaces or foam-gel combinations
• Positioning cushions for calves, elbows, and heels

They do not necessarily need to be expensive — even mid-range models offer significant protection compared to a standard mattress.

Daily skin care

Clean, well-moisturised skin is far more resilient to pressure. Wash vulnerable areas with warm water and gentle soap, drying by patting (not rubbing). Apply moisturising and protective creams daily, particularly to areas exposed to pressure. Avoid products containing alcohol, as these dry the skin.

Stages of pressure sores and when to contact a doctor

Pressure sores progress through four stages, each more serious than the last. Early recognition can make the difference between a simple intervention and a severe complication requiring hospitalisation.

Stage I — The warning sign

The skin remains intact but shows persistent redness that does not disappear when you gently press it with your finger. The area may feel warm to the touch, slightly swollen, or painful. At this stage, the intervention is straightforward: relieve pressure from the affected area, apply protective cream, and monitor it daily. At this stage, healing is rapid if you act immediately.

Stage II — Superficial deterioration

Blisters, abrasions, or superficial ulceration appear — the skin breaks open, forming a wound. The outer layer (epidermis) and the layer beneath it (dermis) are both affected. Stage II pressure sores require specialist care: cleansing, specialist dressings, and usually a consultation with a nurse or GP.

Stages III and IV — Medical emergency

At Stage III, the wound penetrates deep into the fatty tissue, forming a cavity. At Stage IV, the destruction extends to muscle, tendons, or even bone. These severe pressure sores require urgent medical intervention, possibly surgical, and treatment in a hospital setting. The risk of infection is extremely high, and healing can take many months.

When to call a doctor — warning signs

• Any break in the skin or blistering over pressure areas
• Redness that does not disappear within 30 minutes of relieving pressure
• Signs of infection: unpleasant odour, pus, fever, or a very warm area
• Rapid worsening of the wound or appearance of new affected areas
• Severe pain or bleeding from affected areas

Daily skin care routine

A well-established routine transforms pressure sore prevention from a chore into a habit. Here is what a typical day of care for a bedridden elderly person might look like:

Morning

Begin the day with a thorough visual inspection of the skin, paying particular attention to risk areas. Use a mirror for areas that are difficult to see. Wash the entire body with warm water and gentle soap, drying by patting. Apply moisturising cream all over the body, with extra care to areas exposed to pressure. Change bed sheets if they are damp or wrinkled.

Throughout the day

Reposition every two hours, noting the time and position in a notebook to keep track. Check the skin after each repositioning. Ensure the elderly person is drinking enough fluids and receiving balanced meals. After each episode of incontinence, clean the area immediately, dry it thoroughly, and apply a barrier cream.

Evening

Repeat the full skin inspection. Apply moisturising cream again. Check that the mattress and cushions are correctly positioned. Ensure the feet are slightly elevated on cushions overnight to reduce pressure on the heels.

Useful products and equipment

The market offers a wide range of products dedicated to pressure sore prevention. Here is what is worth having to hand:

For skin protection

• Zinc oxide barrier creams — protect the skin from moisture in the perineal area
• Alcohol-free moisturising lotions — maintain skin elasticity
• Vitamin E or aloe vera sprays — soothing and restorative action
• Hydrocolloid dressings — for protecting areas with persistent redness

Positioning equipment

• Pressure-relief mattresses — ranging from simple foam to alternating air systems
• Triangular cushions for maintaining a lateral position
• Specialist heel protectors (heel boots or profiled cushions)
• Transfer (sliding) sheets to avoid friction during repositioning
• Gel or foam cushions for wheelchairs

How to choose the right products

There is no need to buy everything at once. Start with the essentials: a basic pressure-relief mattress, a few positioning cushions, and skin care products. Consult your GP or nurse for personalised recommendations based on the level of risk for your elderly relative. Many medical supply shops allow you to try products before committing or offer a returns guarantee.

Nutrition in the prevention of pressure sores

It may seem surprising, but what your elderly relative eats and drinks has a direct impact on skin health and the body's ability to prevent and heal pressure sores.

Protein — the fuel for tissue repair

Skin and tissues need sufficient protein to regenerate. Bedridden elderly people should consume a variety of sources daily: lean meat, fish, eggs, dairy products, and pulses. If they have difficulty chewing, opt for minced versions, protein pastes, or nutritional supplements recommended by a doctor.

Hydration — vital for skin elasticity

Dehydration makes skin fragile and prone to cracking. Ensure your elderly relative drinks at least 1.5 to 2 litres of fluid daily, provided there are no medical contraindications. Water, herbal teas, soups, natural juices — all contribute. If they refuse to drink, offer fluids in small, frequent portions or foods with a high water content (watermelon, cucumber, yoghurt).

Essential vitamins and minerals

Certain nutrients play a particular role in skin health:

1. Vitamin C — essential for collagen synthesis (citrus fruits, peppers, kiwi, broccoli)
2. Vitamin A — maintains skin integrity (carrots, pumpkin, spinach, liver)
3. Zinc — accelerates healing (seeds, nuts, meat, wholegrains)
4. Vitamin E — protects cells (vegetable oils, nuts, seeds)

If your elderly relative has a poor appetite or dietary restrictions, discuss with their doctor the possibility of introducing specialist nutritional supplements designed for elderly people or those at high risk of pressure sores.

Frequently asked questions

How quickly can pressure sores develop in a bedridden elderly person?

Pressure sores can begin to form in as little as two to three hours of constant pressure, depending on skin fragility and other risk factors. This is why repositioning every two hours is so important.

Can I use talcum powder on an elderly person's skin to keep it dry?

This is not recommended. Talcum powder can clump when it comes into contact with moisture, which increases friction and may irritate the skin. Instead, use barrier creams and change wet incontinence pads or bed linen promptly.

If redness appears, can I massage the area to stimulate circulation?

No. Directly massaging a red area can worsen tissue damage. Instead, relieve all pressure from that area, protect it with specialist dressings, and monitor it closely. If the redness does not disappear within 30 minutes, consult a doctor.

Does a pressure-relief mattress replace the need to reposition the elderly person?

Not entirely. Although pressure-relief mattresses significantly reduce the risk, repositioning remains essential. A mattress is an important aid, but it does not eliminate the need for regular repositioning and attentive skin care.

What should I do if the elderly person refuses to be repositioned because it causes them pain?

Discuss with their doctor the option of administering pain relief before repositioning. Use gentle repositioning techniques, transfer sheets, and explain to the elderly person why it is so important. Sometimes even small movements can help if a full position change is not tolerated.

How much does pressure sore prevention equipment cost?

Costs vary considerably. A basic foam pressure-relief mattress can cost between 200 and 500 RON, whilst alternating air systems range from 1,500 to 3,000 RON. Positioning cushions start from 50 to 100 RON each. Skin care products cost approximately 100 to 200 RON per month. Check with the Casa de Asigurări de Sănătate — under certain conditions, some equipment may be subsidised.

Preventing pressure sores may feel overwhelming at first, but once you establish a clear routine, it becomes a natural part of daily care. Every gesture counts: every repositioning, every application of cream, every glass of water offered. If you feel you need additional support or personalised guidance, do not hesitate to seek professional home care services or to speak with your district nurse. Your elderly relative's skin health deserves this consistent attention.
