Preventing Pressure Injuries (Bedsores) at Home: A Singapore Caregiver's Guide for Bedbound Loved Ones

With Singapore now officially a super-aged society — more than one in five residents is aged 65 and above — more families are caring for elderly relatives who are bedbound or have limited mobility at home. One of the most common, painful, and yet most preventable complications in this situation is the pressure injury, still widely known as a bedsore or pressure ulcer.

This nurse-written guide explains, in plain language, how pressure injuries form, how to spot them early, and the practical home routine that keeps your loved one's skin intact. It is written for family caregivers in Singapore — not clinicians — and always defers to your doctor, polyclinic nurse, or home care team for individual advice.

What exactly is a pressure injury?

A pressure injury is localised damage to the skin and underlying tissue, usually over a bony area, caused by sustained pressure — often combined with shearing (skin dragging) and moisture. When someone lies or sits in one position for too long, the weight of the body squeezes the small blood vessels under the skin. Starved of oxygen, the tissue begins to break down, sometimes within just a couple of hours.

The most vulnerable spots on a person lying in bed are the tailbone (sacrum), heels, hips, shoulder blades, elbows, and the back of the head. For someone who sits for long periods in a wheelchair or recliner, the sitting bones and tailbone are most at risk.

How serious can a bedsore become?

Internationally, clinicians stage pressure injuries from 1 to 4:

• Stage 1: Intact skin with an area of redness that does not turn white (blanch) when you press it. This is the warning stage — and the stage you want to catch.
• Stage 2: Partial-thickness skin loss; a shallow open sore or blister.
• Stage 3: Full-thickness skin loss; the wound is deeper, sometimes exposing fat.
• Stage 4: Deep wound exposing muscle, tendon or bone, with high infection risk.

Deeper pressure injuries can take weeks or months to heal and may need specialist input from a hospital wound centre such as the Changi General Hospital (CGH) Wound Healing Centre, Tan Tock Seng Hospital (TTSH), or Singapore General Hospital (SGH). Prevention is dramatically easier — and kinder — than treatment.

Why is Singapore's climate a hidden risk factor?

Singapore's year-round heat and humidity mean skin is more likely to stay damp from sweat, especially under layers, drawsheets, and adult diapers. Moisture softens the skin (a process called maceration) and makes it far more vulnerable to both pressure and friction. Incontinence adds another layer of moisture and irritation. This is why moisture management is just as important as repositioning for families caring for someone at home here.

The daily prevention routine that works

1. Reposition regularly

The single most important action is to change your loved one's position at least every 2 hours when lying down, and roughly every hour when sitting (or encourage small weight shifts). Alternate between lying on the back and gently turning to each side using a 30-degree tilt, supported with pillows or positioning wedges so bony points are offloaded. Set a phone alarm so the schedule is never forgotten, especially overnight.

2. Protect the skin from moisture

Keep skin clean and dry. Change soiled or wet underpads and adult diapers promptly, cleanse gently with a pH-balanced cleanser or wash mitt rather than vigorous rubbing, and apply a barrier cream or film over areas exposed to moisture. Quality absorbent underpads draw wetness away from the skin and are a simple, high-impact buy for any home care setup.

3. Reduce pressure and friction

Consider a pressure-redistributing foam or alternating-air mattress for anyone bedbound for long periods. Use a draw sheet or slide sheet to move the person rather than dragging them across the bed (dragging causes shearing). Cushion the heels by placing a pillow under the calves so the heels "float" off the mattress. Keep bed linen smooth and crumb-free.

4. Inspect the skin every single day

During each wash or diaper change, look at all the high-risk bony areas. You are hunting for any redness that does not blanch (turn pale) when pressed, plus any warmth, swelling, blisters, or skin that feels firmer or softer than the area around it. On darker skin tones, redness can be harder to see — look instead for colour changes, a purplish hue, or differences in temperature and texture.

5. Support nutrition and hydration

Skin needs protein, calories, fluids and micronutrients to stay resilient and to heal. Poor appetite is common in frail elderly patients, so work with your doctor, dietitian, or pharmacist if you are concerned about intake — oral nutritional supplements may be recommended in some cases.

What supplies should a home caregiver keep on hand?

• Absorbent underpads and drawsheets to manage moisture and protect bedding.
• Skin barrier creams or films for areas exposed to incontinence.
• Foam dressings to cushion and protect early at-risk areas or shallow wounds (on a nurse's advice).
• Gentle cleansers or wash mitts for no-rinse, low-friction skin care.
• Positioning pillows or wedges to hold a 30-degree tilt and float the heels.
• Disposable gloves and antimicrobial cleansers for hygienic dressing changes.

When should you call a professional?

Contact your polyclinic, GP, home nursing provider, or a hospital wound team promptly if you notice any of the following:

• Skin that has broken open, blistered, or formed a sore.
• Redness that does not improve within a day of relieving pressure.
• Signs of infection: spreading redness, warmth, swelling, pus, a foul smell, or fever.
• A wound that is getting larger, deeper, or more painful.

Singapore offers strong community and home-based wound care. Home nursing services (for example through St Luke's Hospital and other providers) can visit to assess and dress wounds, and your polyclinic or GP can refer to a specialist wound centre when needed. Some wound treatments may be partially claimable under MediSave or subsidies, subject to Ministry of Health (MOH) guidelines — ask your care team what applies.

Frequently asked questions

How often should I turn a bedbound person to prevent bedsores?

As a general rule, reposition at least every 2 hours when lying down and about every hour when sitting. Your home nurse may adjust this based on the person's skin condition and risk level.

Can a pressure injury be reversed?

A Stage 1 pressure injury (non-blanching redness with intact skin) can often recover fully if you relieve the pressure early and protect the skin. Once the skin breaks, healing takes much longer and should be managed with professional wound care.

Are underpads or adult diapers enough on their own?

No. Moisture management is essential but it does not replace repositioning and pressure redistribution. The most effective prevention combines regular turning, a suitable mattress, daily skin checks, and good moisture control together.

Is a special mattress really necessary at home?

For anyone bedbound for long stretches, a pressure-redistributing foam or alternating-air mattress significantly lowers risk and is one of the most worthwhile investments a caregiver can make. Discuss the right type with your home care team.
