Elderly bedridden or sedentary prone to bedsores? Causes of pressure ulcers, turning frequency, and care at a glance
Bedsores are mostly caused by prolonged pressure, friction, and moisture on bony prominences. Hospital health education recommends turning bedridden patients at least every 2 hours, avoiding massage of reddened skin, and paying attention to nutrition and skin care.
Why do bedsores occur? Which areas are at higher risk?
According to hospital health education, the main causes and common sites of bedsores (pressure injuries) are as follows:
- Localized damage to skin and subcutaneous tissue caused by prolonged pressure or pressure combined with shear, usually occurring over bony prominences
- Common contributing factors include: sustained pressure on bony prominences without movement, incontinence causing skin moisture, sheet pulling or friction, improper dragging during transfers, and the elderly person's poor nutrition and decreased skin elasticity
- High-risk areas when lying supine: back of the head, shoulder blades, spine, sacrum/coccyx, heels; when lying on side: ears, shoulders, hips (greater trochanter), knees, ankles; when sitting: buttocks (ischium), sacrum/coccyx, heels
- Elderly individuals who are bedridden long-term, use wheelchairs long-term, have sensory deficits (e.g., stroke, spinal cord injury), or are unconscious and unable to turn themselves are at higher risk
How many stages are there for pressure ulcers? From skin redness to deep bone involvement
According to the grading definitions published by the Quality Management Center of National Taiwan University Hospital, pressure injuries are roughly classified into the following levels based on severity (actual wounds must still be assessed by medical staff):
- Stage 1: Intact skin with localized redness that does not blanch when pressed with a finger
- Stage 2: Partial-thickness skin loss with exposed dermis; wound bed is pink or red and moist, possibly with blisters
- Stage 3: Full-thickness skin loss, visible subcutaneous fat and granulation tissue, but not extending to muscle, tendon, or bone
- Stage 4: Full-thickness skin and tissue loss, deep enough to expose or palpate fascia, muscle, tendon, ligament, cartilage, or bone
- Once the skin shows 'redness that does not blanch with pressure,' it is already an early warning sign of pressure ulcers; it is recommended to increase the frequency of turning and skin inspection, rather than waiting until the skin breaks
How to determine turning frequency? How to choose skin care and pressure-relieving aids?
Hospital health education provides the following specific practices:
- Bedridden patients should generally be assisted to turn at least every 2 hours, alternating between left side, supine, and right side; if the skin is already red or has wounds, increase turning frequency
- Wheelchair users are advised to perform buttock lifts (or lean forward) every 15 minutes to relieve pressure for about 10 seconds, and change sitting position at least every hour
- After bathing or incontinence, keep the skin dry; apply lotion or skin protectant spray as needed to avoid prolonged moisture
- When turning or assisting the elderly with transfers, avoid massaging bony prominences or already reddened skin areas—massage may cause additional damage to already compressed and injured tissues; the correct approach is to observe and record skin changes, not to rub
- Bedridden patients can use aids such as alternating pressure mattresses, pressure-relieving foam, and pressure-relieving cushions to reduce local pressure, but these aids only help distribute pressure and cannot replace turning; regular turning or position changes must still be performed
Does nutrition and fluid intake help prevent pressure ulcers?
Skin integrity and wound healing are related to nutritional status. Hospital health education recommends:
- Consume adequate calories and high-protein foods (such as eggs, milk, meat, soybeans and soy products); insufficient nutrition reduces skin elasticity and makes it more prone to damage
- Some health education materials suggest also paying attention to vitamin C and zinc intake, as both are related to wound repair
- Fluid intake is equally important; actual needs should be assessed by a physician or dietitian based on the elderly person's kidney function, heart function, etc., and should not be supplemented excessively without guidance
- If the elderly person also experiences decreased appetite and weight loss, it is recommended to monitor whether nutritional status is deteriorating (refer to this site's 'Malnutrition Warning Signs' explanation), rather than only addressing skin surface issues
Are aids like alternating pressure mattresses subsidized by Long-Term Care 2.0? When to seek medical attention?
In addition to home care, if the elderly person meets eligibility criteria, they can apply for assistive devices through the long-term care system; seek medical attention when specific changes occur:
- According to the assistive device service items announced by the Ministry of Health and Welfare's Long-Term Care Service Section (1966 hotline), 'Alternating Pressure Mattress - Type A' (code EG01) and 'Alternating Pressure Mattress - Type B' (code EG02) are both listed as service items, available for rental or purchase
- The application process is: individuals who meet long-term care eligibility are assessed at home by a care manager to confirm the need for assistive devices, then referred to the local municipal or county (city) competent authority for processing; it is not automatically granted upon reaching a certain age
- Long-Term Care 2.0 service targets generally include disabled elderly aged 65 and above, disabled indigenous people aged 55 and above, individuals with dementia aged 50 and above, and disabled persons with disabilities of any age (actual disability level and eligibility are determined by the care manager's assessment)
- Actual subsidy amounts, co-payment ratios, and latest regulations may vary by county/city and individual case assessment; it is recommended to directly call the 1966 long-term care hotline or consult the local care management center for confirmation
- If the elderly person's skin shows redness that does not blanch with pressure, blisters, broken skin, or the wound has exudate, odor, surrounding redness, swelling, heat, pain, or fever, seek medical attention promptly for evaluation of whether further wound management is needed
FAQ
How often should a bedridden elderly person be turned?
According to hospital health education, bedridden patients should generally be assisted to turn at least every 2 hours, alternating between left side, supine, and right side. If the skin is already red or has wounds, the turning frequency should be increased rather than maintaining a fixed 2-hour interval. For wheelchair users, it is recommended to perform buttock lifts or lean forward every 15 minutes to relieve pressure, and change sitting position at least every hour.
If the skin is red, can I massage it vigorously to make it fade?
It is not recommended. Hospital health education indicates that massaging bony prominences or already reddened skin during turning or care should be avoided, as massage may cause additional damage to already compressed and injured tissues. The correct approach is to continuously observe skin changes, record whether the area is expanding, and increase turning frequency. If there is no improvement, consult medical staff.
How many stages are there for pressure ulcers? How can I tell if the wound is severe?
According to hospital grading definitions, pressure injuries are roughly divided into four stages: Stage 1 is intact skin with localized redness that does not blanch when pressed; Stage 2 is partial-thickness skin loss with exposed dermis; Stage 3 is full-thickness skin loss with visible fat and granulation tissue; Stage 4 is deep enough to expose or palpate muscle, tendon, ligament, or bone. Actual staging and severity must be assessed by medical staff after examining the wound; self-grading and delaying medical attention is not recommended.
If we use an alternating pressure mattress at home, do we still need to turn the elderly person?
No. Hospital health education reminds that aids such as alternating pressure mattresses and pressure-relieving foam can only help distribute pressure and reduce risk, but cannot replace turning itself. Even with an alternating pressure mattress, bedridden patients should still have regular turning or position changes; using both together yields better results.
Does Long-Term Care 2.0 subsidize alternating pressure mattresses? How to apply?
According to the assistive device service items announced by the Ministry of Health and Welfare's Long-Term Care Service Section, 'Alternating Pressure Mattress - Type A' and 'Alternating Pressure Mattress - Type B' are both listed as service items, available for rental or purchase. However, a care manager must first conduct an in-home assessment to confirm that the elderly person meets long-term care eligibility and has an actual need, before referral to the local competent authority for processing. For actual subsidy amounts and co-payment ratios, it is recommended to call the 1966 long-term care hotline or consult the local care management center.
What changes in an elderly person's bedsore wound require immediate medical attention?
If the skin shows redness that does not blanch with pressure, blisters, broken skin, or the wound has exudate, odor, surrounding redness, swelling, heat, pain, or even systemic symptoms such as fever, it is recommended to seek medical attention promptly. Medical staff should evaluate whether further wound debridement or treatment is needed; do not rely solely on home dressing changes and observation.
