Restraints in healthcare are any methods used to limit a person’s movement or behavior to prevent them from harming themselves or others. They fall into three main categories: physical, chemical, and environmental. Each works differently, carries specific risks, and is governed by strict legal requirements about when and how long it can be used.
Types of Restraints
Physical Restraints
A physical restraint is any action or device that prevents a person from moving freely to a position of their choice, using something attached to or placed next to their body that they can’t easily control or remove. Common examples include soft wrist restraints, lap belts, vests, jackets, and mitts that cover the hands. Some devices specifically prevent bending at the elbows, knees, wrists, or ankles. Bed rails, when used to keep someone from getting out of bed rather than to prevent rolling, also count as physical restraints.
Chemical Restraints
Chemical restraints involve giving someone medication specifically to control their behavior rather than to treat a diagnosed condition. Sedatives, anti-anxiety drugs, and antipsychotic medications all qualify as chemical restraints when the purpose is to restrict what a person can do. The key distinction is intent: the same medication prescribed to treat a psychiatric disorder is therapy, but the same medication given primarily to make someone easier to manage is a chemical restraint. There is no international consensus definition for chemical restraint, which makes this line blurry in practice.
Environmental Restraints
Environmental restraints restrict movement by changing a person’s surroundings. Locking someone in their room, using keypad-locked ward doors, repositioning furniture to block movement, and electronic surveillance systems all fall into this category. These are generally considered a subtype of physical restraint, even though no device is directly attached to the person’s body.
Why Restraints Are Used
Restraints are used when someone poses an immediate safety risk. In hospital settings, this often means a patient is pulling out breathing tubes, IV lines, or surgical drains. In psychiatric or long-term care settings, it may mean a person is physically aggressive toward staff or other patients, or is engaging in self-harm. Staff in emergency departments also use restraints when a patient’s behavior creates danger that can’t be managed any other way.
The core justification is always the same: the person’s safety, or the safety of those around them, is at immediate risk and no less restrictive option is working.
Risks and Complications
Restraints carry serious medical risks. Physically restrained patients in intensive care units are six times more likely to develop pressure injuries compared to unrestrained patients. Up to 30% of restrained ICU patients develop visible skin damage, including bruising, redness, swelling, ulcers, and in severe cases, tissue death at the restraint site.
The risks go well beyond skin injuries. Restrained patients face higher rates of blood clots in the legs, aspiration pneumonia (inhaling food or fluid into the lungs), and other hospital-acquired infections. Paradoxically, restraints can actually increase agitation rather than reduce it, leading some patients to fight harder against the devices. Restrained patients also experience longer hospital stays and higher mortality rates.
Strangulation is the most dangerous acute risk, particularly with vest and jacket restraints when a patient slides down in bed. Prolonged immobility from restraint use also leads to muscle weakening and joint stiffness over time, especially in older adults.
The Ethical Tension
Restraint use creates a genuine moral conflict for healthcare workers. Nurses in particular face the dilemma of weighing a patient’s right to autonomy against their obligation to keep that patient safe. When a confused elderly patient tries to pull out a feeding tube, for example, respecting their bodily autonomy means accepting they might seriously injure themselves.
The ethical framework is straightforward in principle: restraints should only be used when the harm of not restraining clearly outweighs the harm of restraining. In practice, this calculation is difficult. Staff may bear legal responsibility if an unrestrained patient is injured, which can push decisions toward restraint even when the situation is ambiguous. Outside of genuine safety emergencies, restraint use conflicts with the basic medical principle of doing no harm, given the well-documented physical and psychological risks.
Informed consent and shared decision-making are considered essential whenever possible. Explaining to patients (or their families) what restraints involve and why they’re being considered respects their dignity even when their autonomy is being limited.
Legal Requirements
Federal regulations set strict limits on restraint use in the United States. Every use of restraint requires a physician’s order that includes the ordering provider’s name, the date and time, the specific intervention, and the authorized duration. Orders cannot exceed four hours for adults ages 18 to 21, two hours for those ages 9 to 17, and one hour for children under 9. Each order must be limited to the duration of the emergency, and staff must document the situation that made restraint necessary before the end of their shift.
These regulations mean restraints cannot be ordered on an indefinite or “as needed” basis. Each episode requires its own assessment, its own order, and its own documentation.
Alternatives That Reduce Restraint Use
About 90% of emergency departments report trying alternatives before applying restraints. The most common first step is simply talking with the patient one-on-one, followed by offering a time-out or pastoral care. These approaches work more often than many people expect.
In long-term care settings for older adults, the most effective alternatives focus on individualized daily routines: keeping a consistent schedule, ensuring regular meals, managing pain proactively, and making everyday activities like bathing and dressing as easy as possible. For people with cognitive decline, reducing confusion through predictability often eliminates the behaviors that would otherwise lead to restraint.
On hospital wards and psychiatric units, several strategies have proven effective. Training staff in de-escalation and crisis management techniques reduces restraint use significantly. Review committees where staff and families examine the circumstances around each restraint episode have cut incidents by 34% in some facilities. Increasing the staff-to-patient ratio gives nurses more time for direct interaction, which lowers aggression. Even changes to the physical environment, like reducing noise levels and adjusting lighting, can decrease the agitation that leads to restraint.
The consistent finding across settings is that the more present and engaged staff are with patients, the less restraint is needed. Regular conversation, attentive monitoring, and quick responses to discomfort or confusion address the root causes of unsafe behavior rather than simply suppressing the behavior itself.
