4.3 Restraint Alternatives & Patient Safety
Key Takeaways
- Federal regulations under OBRA 1987 strictly guarantee residents the right to be free from physical and chemical restraints imposed for discipline or staff convenience.
- Restraint alternatives—such as low-bed positioning, sensor alarms, structured activity programs, and scheduled toileting—must be attempted and documented before physical restraints are considered.
- If a physician orders a physical restraint for medical necessity, the CNA must check the resident's skin, circulation, and comfort every 15 minutes and remove the restraint every 2 hours for at least 10 minutes.
- Complications of physical restraint use include pressure injury, muscle atrophy, nerve damage, strangulation, increased agitation, and deep vein thrombosis.
4.3 Restraint Alternatives & Patient Safety
Clinical Core Concept: Residents in licensed long-term care facilities possess a legal and ethical right to be free from physical and chemical restraints. The Nursing Home Reform Act (OBRA 1987) strictly limits restraint use. CNAs play a critical role in implementing creative, person-centered restraint alternatives to protect resident safety and preserve dignity.
1. Principles of Restraint-Free Care & OBRA Guidelines
A physical restraint is any manual method, physical or mechanical device, material, or equipment attached or adjacent to the resident's body that the individual cannot remove easily, which restricts freedom of movement or normal access to one's body.
A chemical restraint is any medication given to control a resident's behavior or restrict freedom of movement when the medication is not standard treatment for the resident's medical or psychiatric condition.
OBRA 1987 Standards & Resident Rights
- Restraints may NEVER be used for discipline, punishment, or staff convenience.
- Restraints may only be used as an extreme last resort to treat medical symptoms when a resident poses an immediate, serious physical danger to themselves or others.
- Physician Order Required: Physical restraints require a specific, written order from a licensed physician specifying the medical reason, exact type of restraint, location, and precise duration. Standing orders or PRN (as-needed) restraint orders are strictly illegal.
2. Severe Risks & Complications of Physical Restraint Use
Historical assumptions that physical restraints prevent injuries have been thoroughly disproven. Physical restraints frequently increase injury severity and cause catastrophic physical and psychological harm:
| Category | Clinical Hazard / Complication | CNA Assessment Finding |
|---|---|---|
| Integrum & Skin | Severe friction abrasions, tears, pressure injuries | Redness, skin breakdown, bruising under restraint straps |
| Circulatory | Constriction of arterial/venous blood flow, edema, DVT | Cold extremity, pale or cyanotic nail beds, weak or absent pulse |
| Musculoskeletal | Rapid muscle atrophy, joint contractures, osteoporosis | Decreased range of motion, muscle weakness, stiffness |
| Respiratory | Chest compression, asphyxiation, strangulation | Shallow breathing, dyspnea, accidental death from sliding down |
| Psychological | Entrapment anxiety, severe depression, combative agitation | Screaming, withdrawal, delirium, loss of dignity |
3. Person-Centered Restraint Alternatives
Before any physical restraint can be considered, the interdisciplinary care team must attempt and document restraint alternatives. CNAs implement these alternatives during daily routines:
Environmental Adaptations
- Low Beds & Floor Mats: Placing beds in their lowest position next to cushioned floor mats prevents fall injuries without restricting movement.
- Positioning Devices: Using foam wedges, body pillows, or concave mattress pads to provide physical comfort and postural support.
- Motion Sensors & Bed/Chair Alarms: Installing electronic pressure pads or infrared motion sensors to alert nursing staff immediately when a resident attempts to ambulate unassisted.
Individualized Nursing Interventions
- Scheduled Toileting Programs: Escorting restless residents to the bathroom every 2 hours to eliminate the urge to wander.
- Addressing Physical Comfort: Systematically evaluating residents for unmet needs such as pain, hunger, thirst, full bladder, or feeling cold.
- Targeted Distraction & Activities: Providing folding tasks, activity aprons, fidget blankets, music therapy, or peaceful walks with staff.
- De-escalation Techniques: Using a calm, gentle tone of voice, reducing environmental noise, and offering familiar objects.
4. Care Guidelines for Physician-Ordered Restraints
When all alternatives fail and a physician issues a legal restraint order, the CNA must strictly execute required monitoring and direct care standards:
- EVERY 15 MINUTES: Perform safety and circulatory checks on the restrained resident.
- EVERY 2 HOURS: Completely remove the restraint for at least 10 minutes to deliver essential physical care.
15-Minute Safety & Circulation Checks
- Verify the restraint is applied correctly and has not shifted toward the throat or chest.
- Inspect skin integrity under and surrounding the device.
- Assess pulse, skin color, temperature, and capillary refill in restrained limbs.
- Ensure the resident is breathing comfortably without chest restriction.
2-Hour Restraint Release & Direct Care Routine (Minimum 10 Minutes)
- Remove Restraint Completely: Release straps to restore unrestricted movement.
- Perform Range-of-Motion (ROM): Gently flex and extend joints to prevent contractures and promote circulation.
- Skin & Hygiene Care: Inspect skin, cleanse, dry, and apply moisturizer; reposition the resident to relieve pressure.
- Toileting & Hydration: Offer bedpan, urinal, or escort to bathroom; offer water or nutritional fluids.
- Re-evaluating Necessity: Re-apply the restraint only if the medical symptom persists and safety demands it.
5. Safe Restraint Application Protocols
If assigned to apply a physician-ordered restraint (e.g., wrist restraint, vest restraint, belt restraint):
- Quick-Release Knot: Always tie restraint straps using a quick-release knot (such as a slip knot or half-hitch) so staff can instantly release the device in an emergency.
- Attachment Point: Secure straps directly to the movable frame of the bed (or wheelchair frame). NEVER tie restraint straps to side rails, as lowering the bed rail will pull the restraint tight, causing severe injury or strangulation.
- Proper Fit Test: Ensure you can easily insert two fingers between the restraint device and the resident's body/wrist to prevent circulatory constriction.
6. Clinical Scenario: Implementing Restraint Alternatives
Scenario: Mrs. Gable has moderate vascular dementia and repeatedly attempts to stand up unassisted from her wheelchair, placing her at extreme risk of falls due to recent hip surgery. The nurse asks CNA David to implement restraint alternatives rather than using a lap belt.
Correct CNA Intervention: David implements person-centered alternatives: he installs a tab-alarm sensor on her wheelchair that sounds a gentle chime when her back leaves the seat cushion. He reviews her care plan and establishes a scheduled toileting routine every 90 minutes. Recognizing Mrs. Gable was formerly a seamstress, David provides her with a basket of fabric swatches and ribbon to organize at the nursing station table. Mrs. Gable remains happily engaged, her toileting needs are met, and her unassisted transfer attempts drop to zero without using physical restraints.
