How Often Should Bed-Bound Residents Be Repositioned?

A bed-bound resident is an individual unable to change their body position to relieve pressure, typically due to illness, severe injury, or limited mobility. Repositioning is a fundamental component of quality care designed to maintain skin integrity and promote overall health. Sustained pressure of the body against a surface can rapidly damage underlying tissues. The goal is to redistribute weight regularly, preventing complications that arise from immobility.

Standard Guidelines for Repositioning Frequency

The universally recognized baseline for bed-bound residents is the “2-hour rule,” which dictates that a person must be physically repositioned at least every two hours around the clock. This time frame is based on medical consensus, acknowledging that tissues can typically withstand continuous pressure for about 120 minutes before irreversible damage begins. Repositioning involves a complete change of position, such as turning the individual from their back to a side-lying position. The European Pressure Ulcer Advisory Panel (EPUAP) and the National Pressure Injury Advisory Panel (NPIAP) suggest that a 30-degree lateral incline is the preferred side-lying position, as this avoids placing weight directly onto the prominent hip bone.

Patients who are able to sit up in a chair or wheelchair require more frequent attention. The standard guideline for a seated resident is to reposition or shift their weight at least every hour. For individuals who can manage it, a weight shift or a slight lean from side to side should be performed every 15 minutes to briefly relieve pressure on the buttocks and tailbone.

The Importance of Pressure Injury Prevention

The strict repositioning schedule is primarily a defense against the development of pressure injuries, commonly known as bedsores or pressure ulcers. These injuries begin when sustained pressure exceeds the normal capillary closing pressure (roughly 32 mm Hg). This pressure compresses small blood vessels, leading to restricted blood flow called ischemia. Without oxygen and nutrients, affected cells and tissues begin to die (necrosis), quickly leading to skin breakdown.

Pressure injuries most often form over bony prominences where soft tissue padding is minimal, concentrating body weight onto a small area. The most common sites are the sacrum (tailbone area), the heels, the hips, the elbows, and the back of the head. Friction (skin rubbing against a surface) and shear (skin staying put as underlying tissue slides) can accelerate this damage. Healthcare professionals use standardized tools, such as the Braden Scale, to assess an individual’s risk factors for developing these wounds.

The consequences of inaction extend far beyond the skin, as an open pressure injury can rapidly progress to involve deeper muscle and bone. Uncontrolled wounds introduce a pathway for infection, potentially leading to osteomyelitis or life-threatening systemic sepsis. Consistent, proactive repositioning is the most fundamental intervention to prevent this serious complication.

Factors That Modify the Repositioning Schedule

While the two-hour rule is the standard baseline, a resident’s individual risk profile often requires a more aggressive schedule. Patients with existing skin integrity issues, such as redness that does not disappear quickly when pressure is relieved, may need to be turned every 90 minutes or even hourly. Individuals with poor nutritional status, including malnutrition or dehydration, are at higher risk because their skin is more fragile and their body’s ability to repair damaged tissue is compromised.

Certain medical conditions also increase the frequency needed for turning, such as severe edema (swelling) or poor circulation due to conditions like diabetes. The treatment plan must be customized based on a thorough assessment of these factors. Specialized support surfaces, such as alternating air mattresses, can help redistribute pressure. However, equipment should never replace the need for manual repositioning. The key is to establish an individualized turning regimen that ensures the tissue is sufficiently offloaded to prevent injury.
