6.3 Restraints, Restraint Alternatives, and OBRA Requirements
Key Takeaways
- OBRA gives every resident the right to be free from restraints used for discipline or staff convenience
- Restraints require a physician's order for a specific medical reason and must use the LEAST restrictive device for the shortest time
- A restrained resident is checked at least every 30 minutes and released at least every 2 hours for range of motion, toileting, fluids, and repositioning
- Restraints can cause strangulation, skin breakdown, impaired circulation, contractures, depression, and MORE falls — they increase risk, not safety
- Alternatives a CNA can use include bed/chair alarms, low beds, floor mats, scheduled toileting, activities, and one-on-one attention
- The two-finger rule: you must be able to slide two fingers between the restraint and the resident's skin to confirm it is not too tight
Restraints Are One of the Most Regulated Topics in Long-Term Care
The Omnibus Budget Reconciliation Act (OBRA) of 1987 and Illinois law sharply restrict both physical and chemical restraints. Every resident has the right to be free from any restraint that is not medically necessary and ordered by a physician. This is a heavily tested topic on the INACE, and the safe answer almost always favors the least restrictive option.
What Counts as a Restraint
| Type | Definition | Examples |
|---|---|---|
| Physical restraint | Any device or method that the resident cannot remove and that restricts free movement or normal access to the body | Vest/jacket restraints, wrist or ankle restraints, lap belts, fixed lap trays, and side rails used to keep a resident in bed |
| Chemical restraint | A drug used to control behavior or for convenience rather than to treat a diagnosed medical condition | Sedatives or antipsychotics given just to calm or quiet a resident |
A key trap: the same device can be either a restraint or not, depending on use and the resident. A side rail a resident uses to reposition is an aid; the same rail raised to stop a confused resident from getting up is a restraint. A lap tray the resident can remove is fine; one they cannot remove restrains them.
OBRA Restraint Rules
| Rule | Detail |
|---|---|
| Resident right | Freedom from restraint for discipline or staff convenience |
| Medical necessity | Only used to treat a specific medical symptom, never as a fall "fix" |
| Physician order | Required, stating reason, type, and duration |
| Least restrictive | Use the least restrictive device for the shortest possible time |
| Reassessment | Continued need must be re-evaluated regularly |
| Release | Released at least every 2 hours |
| Monitoring | Checked at least every 30 minutes |
| Documentation | All checks, releases, and observations recorded |
Why Restraints Are Dangerous
Restraints frequently cause more harm than the risk they were meant to prevent.
| Danger | Why It Happens |
|---|---|
| Strangulation / asphyxiation | A vest or rail can shift and compress the neck or chest — the leading cause of restraint death |
| Skin breakdown | Constant pressure and friction from the device |
| Impaired circulation | A restraint that is too tight cuts off blood flow |
| Nerve damage | Pressure on nerves at the wrist or ankle |
| Increased agitation | Loss of control often makes residents more upset |
| MORE falls | Residents climb over rails or out of restraints and fall harder |
| Contractures | Immobility shortens muscles and stiffens joints |
| Depression and loss of dignity | Lost autonomy harms emotional health |
Restraint Alternatives a CNA Can Implement
Alternatives are always tried before restraints. Most are squarely within your scope.
| Alternative | How It Helps |
|---|---|
| Bed or chair alarm | Alerts staff when the resident tries to rise, no movement restriction |
| Low bed | Reduces injury if the resident slides or rolls out |
| Floor mat beside the bed | Cushions a fall from bed |
| Scheduled toileting | Removes the urgency that drives unassisted standing |
| Meaningful activities | Reduces wandering, boredom, and agitation |
| One-on-one attention or sitters | Comforts an anxious or restless resident |
| Reclining or wedge cushion chairs | Provide positioning support without restraint |
| Pain management (report promptly) | Untreated pain is a common cause of agitation |
| Adequate lighting and orientation | Reduces confusion and sundowning |
CNA Responsibilities When a Restraint Is Ordered
If a physician orders a restraint, you must:
- Check the care plan for the exact type, schedule, and release plan.
- Apply only restraints you are trained on, using a quick-release knot — never a fixed knot — tied to the movable bed frame, not the side rail.
- Use the two-finger rule — you must slide two fingers between the restraint and the skin to confirm it is not too tight.
- Release at least every 2 hours for range of motion, toileting, fluids, skin care, and repositioning.
- Monitor at least every 30 minutes for breathing, circulation, skin integrity, and comfort.
- Document every check and release.
- Report immediately any distress, color change, swelling, or skin breakdown to the nurse.
Worked Example: A Wandering Resident
Mr. Choi has dementia and keeps trying to leave his chair, and a coworker suggests "just put a lap belt on him." The correct path is to try alternatives first: a chair alarm, a reclining chair, a structured activity, a check for pain or a full bladder, and one-on-one company. A lap belt could only be used later if those failed, the resident had a clear medical reason, a physician ordered it, and it was the least restrictive option — and even then you would check him every 30 minutes, release it every 2 hours, and use the two-finger rule.
If you simply applied the belt for convenience, you would be violating his OBRA rights and risking strangulation, more falls, and skin breakdown.
Reporting and the Resident's Rights
Always report a request to restrain a resident "for convenience" to the nurse rather than acting on it. The resident also keeps the right to refuse, and a properly applied, ordered restraint must still allow access to the call light. Quality-of-life measures — answering call lights promptly, meeting toileting and comfort needs, and reducing noise and confusion at night — are the real long-term strategy for a restraint-free environment, which is the federal and Illinois standard of care.
Common Exam Traps
The exam loves "safety" distractors that are actually restraints or staff convenience: a sedative "to keep the resident calm," tying a sheet across the lap, or raising all four side rails so a resident cannot get up. None are acceptable without a documented medical order, and the wandering or fall-risk resident calls for an alternative first. Remember the numbers — 30 minutes to check, 2 hours to release — and tie restraints to the movable bed frame with a quick-release knot, never to the side rail. A device the resident can remove independently is generally not a restraint, while the identical device that traps them is.
Under OBRA, a physical restraint may be applied only when:
