Patients in hospital beds are rotated every 2 hours to prevent bedsores exactly why is this effective?

While patients in hospital beds are rotated every 2 hours to prevent bedsores, current clinical practice, and studies don't support this specific 2-hour time interval as being universally effective in preventing pressure injuries (bedsores). The effectiveness of pressure injury prevention strategies depends on various factors, including the patient's condition, skin integrity, and overall care regimen.

Pressure injuries, also known as bedsores or pressure ulcers, occur when there is unrelieved pressure on the skin and underlying tissues, cutting off blood flow and causing damage. Factors such as immobility, incontinence, and malnutrition increase the risk of developing pressure injuries.

Here's why regular patient rotation is important, irrespective of a specific time interval:

1. Preventing Prolonged Pressure: Regularly changing a patient's position helps distribute weight and pressure on different areas of the body, reducing the risk of pressure sores developing on specific parts.

2. Enhancing Circulation: Shifting positions improves blood flow and circulation, which is essential for maintaining skin health and preventing tissue damage.

3. Encouraging Mobility: Depending on the patient's condition and ability, encouraging small movements and repositioning can help stimulate blood flow and prevent stiffness.

4. Reducing Shear Forces: Sliding or pulling a patient during rotation should be avoided to minimize shear forces on the skin. Instead, gentle lifting techniques are recommended.

5. Skin Care: Regular inspection of the skin and providing proper skin care, such as moisturizing, can help maintain skin integrity.

It's crucial for healthcare professionals to assess each patient's individual needs and modify the frequency and techniques of rotation based on factors like their mobility, risk assessment, and medical condition.

Instead of relying solely on a specific time interval, a personalized and comprehensive approach to pressure injury prevention is recommended, considering factors such as patient risk assessment, use of appropriate support surfaces, nutritional support, and education for healthcare providers and patients/caregivers.
