How Often Should Residents In Wheelchairs Be Repositioned

Navigating the intricacies of care for wheelchair-bound residents requires a deep understanding of their unique needs, especially concerning repositioning. Proper repositioning is paramount in preventing pressure ulcers, promoting circulation, and enhancing overall comfort. But how often should residents in wheelchairs be repositioned? This comprehensive guide delves into the science, best practices, and individualized approaches to ensure optimal care.

Understanding the Importance of Repositioning

Prolonged sitting in a wheelchair can lead to a host of complications. The constant pressure on bony prominences restricts blood flow, which is a primary cause of pressure ulcers, also known as bedsores or pressure injuries. These ulcers can range from minor skin irritations to deep, infected wounds that require extensive medical intervention.

Repositioning is the act of changing a person's posture or position. It serves several critical functions:

• Relieving Pressure: Shifting weight away from areas susceptible to pressure ulcers.
• Improving Circulation: Enhancing blood flow to tissues, promoting healing and preventing tissue damage.
• Enhancing Comfort: Providing relief from discomfort and stiffness.
• Promoting Skin Integrity: Reducing the risk of skin breakdown and irritation.
• Preventing Contractures: Maintaining joint flexibility and preventing muscle shortening.

The General Guideline: Every Two Hours

The most commonly cited guideline for repositioning wheelchair-bound residents is every two hours. This standard is rooted in research and clinical experience, suggesting that this frequency is generally sufficient to prevent pressure ulcers in most individuals.

However, it's crucial to recognize that this is a general guideline and not a one-size-fits-all rule. Individual needs can vary significantly based on a range of factors, which we will explore in subsequent sections.

Factors Influencing Repositioning Frequency

Several factors necessitate adjusting the standard two-hour repositioning schedule. A comprehensive assessment of each resident is essential to determine the most appropriate repositioning frequency.

1. Risk Factors for Pressure Ulcers

Identifying residents at high risk for pressure ulcers is the first step in tailoring a repositioning plan. Key risk factors include:

• Immobility: Limited ability to change positions independently.
• Sensory Impairment: Reduced ability to feel pressure or discomfort.
• Incontinence: Exposure to moisture, which can weaken the skin.
• Poor Nutrition: Inadequate intake of protein, vitamins, and minerals, hindering tissue repair.
• Chronic Medical Conditions: Diabetes, vascular disease, and other conditions that impair circulation.
• History of Pressure Ulcers: Previous ulcers indicate a higher susceptibility.
• Age: Older adults generally have thinner skin and reduced tissue elasticity.
• Body Weight: Both underweight and obese individuals are at increased risk.

Residents with multiple risk factors may require more frequent repositioning, possibly every hour or even more often, depending on the severity of their risk profile.

2. Individual Skin Assessment

Regular skin assessments are vital for detecting early signs of pressure ulcers. The assessment should include:

• Visual Inspection: Checking for redness, discoloration, blisters, or breaks in the skin.
• Palpation: Gently feeling for areas of hardness, warmth, or tenderness.
• Braden Scale Assessment: Using a validated tool like the Braden Scale to assess pressure ulcer risk based on sensory perception, moisture, activity, mobility, nutrition, and friction/shear.

If skin assessments reveal early signs of pressure ulcers, such as persistent redness that doesn't blanch with pressure, repositioning frequency should be increased, and other preventive measures should be implemented immediately.

3. Wheelchair Cushion and Support Surfaces

The type of wheelchair cushion and support surfaces significantly impacts pressure distribution.

• Standard Cushions: Offer basic support but may not effectively redistribute pressure.
• Gel Cushions: Provide better pressure redistribution than standard cushions.
• Air Cushions: Offer the best pressure redistribution and are ideal for high-risk individuals.
• Specialty Back Supports: Help maintain proper posture and reduce pressure on the spine.

Residents using standard cushions may require more frequent repositioning than those using advanced pressure-redistributing cushions. Regularly inspect cushions for wear and tear, ensuring they provide adequate support.

4. Resident Comfort and Tolerance

While adhering to repositioning schedules is essential, resident comfort and tolerance should also be considered. Some individuals may experience discomfort or anxiety with frequent repositioning.

• Communicate with Residents: Explain the importance of repositioning and address any concerns.
• Involve Residents in the Process: Encourage residents to participate in repositioning if possible.
• Adjust Schedules Based on Tolerance: If a resident consistently experiences discomfort with a specific repositioning schedule, consider adjusting the frequency or technique.
• Pain Management: Address any underlying pain that may be exacerbated by repositioning.

5. Resident Activity Level

A resident's activity level also influences repositioning needs.

• Active Residents: Residents who can independently shift their weight or perform pressure relief exercises may not require repositioning as frequently.
• Passive Residents: Residents who are completely immobile require more frequent and thorough repositioning.

Encouraging active residents to perform regular weight shifts can supplement scheduled repositioning and promote independence.

Repositioning Techniques

Effective repositioning involves more than just changing positions. Proper techniques are crucial to prevent injury and maximize benefits.

1. Weight Shifting

Weight shifting involves gently leaning the resident to one side, then the other, to relieve pressure on the buttocks and sacrum. This can be done independently by some residents or with assistance from caregivers.

• Independent Weight Shifting: Teach residents to lean to each side for 15-30 seconds every 15-30 minutes.
• Assisted Weight Shifting: Caregivers can assist residents by gently tilting the wheelchair or using their hands to shift the resident's weight.

2. Pressure Relief Exercises

Pressure relief exercises involve lifting the body off the wheelchair seat to relieve pressure on the buttocks and sacrum.

• Independent Pressure Relief: Teach residents to push up from the armrests or use a specialized device to lift themselves off the seat.
• Assisted Pressure Relief: Caregivers can assist residents by lifting them slightly off the seat.

3. Full Repositioning

Full repositioning involves changing the resident's position in the wheelchair, such as from sitting upright to reclining or tilting.

• Reclining: Reclining the wheelchair can redistribute pressure and improve comfort.
• Tilting: Tilting the wheelchair can relieve pressure on the buttocks and sacrum.
• Lateral Positioning: Positioning the resident on their side can relieve pressure on the sacrum and hips.

When performing full repositioning, ensure proper body alignment and support to prevent injury.

4. Use of Assistive Devices

Various assistive devices can aid in repositioning and pressure relief.

• Transfer Boards: Facilitate lateral transfers between the wheelchair and other surfaces.
• Mechanical Lifts: Assist in lifting and transferring residents, reducing the risk of injury to both the resident and caregiver.
• Specialty Wheelchairs: Offer features such as tilt-in-space and recline to facilitate repositioning.

Implementing a Repositioning Schedule

Creating and implementing a personalized repositioning schedule is essential for providing consistent and effective care.

1. Assessment and Planning

• Comprehensive Assessment: Conduct a thorough assessment of the resident's risk factors, skin condition, and activity level.
• Develop a Care Plan: Create a personalized care plan that outlines the repositioning schedule, techniques, and assistive devices to be used.

The Science Behind Repositioning

Understanding the scientific principles behind repositioning can help caregivers appreciate its importance and implement it more effectively.

1. Pressure and Tissue Damage

Prolonged pressure on tissues restricts blood flow, leading to ischemia (lack of oxygen) and tissue damage.

• Capillary Closing Pressure: The pressure at which blood flow is occluded in capillaries is typically around 32 mm Hg.
• Time and Pressure: The higher the pressure and the longer the duration, the greater the risk of tissue damage.

Repositioning reduces pressure on tissues, allowing blood flow to return and preventing ischemia.

2. Shear and Friction

Shear occurs when layers of tissue slide against each other, causing damage to blood vessels and tissues. Friction occurs when the skin rubs against a surface, leading to skin breakdown.

• Minimize Shear and Friction: Use proper lifting techniques and avoid dragging residents across surfaces.
• Use Protective Barriers: Apply barrier creams or dressings to protect the skin from friction.

3. Inflammation and Healing

Pressure ulcers trigger an inflammatory response, which can delay healing.

• Promote Healing: Ensure adequate nutrition, hydration, and wound care to promote healing.
• Manage Pain: Manage pain to improve comfort and promote healing.
