Patient Safety & Systems-Based Practice

Restraint use: indications, alternatives, monitoring

Clinical Overview and When to Consider Restraints

— Non-violent/medical-surgical restraint: to protect medical devices or prevent interference with care (e.g., confused ICU patient pulling at ETT, central line, NG tube)

— Violent/self-destructive restraint: to prevent imminent harm to self or others (agitated psychiatric or delirious patient swinging at staff)

— Acutely agitated delirious elderly patient pulling at lines after non-pharmacologic measures fail

— Postoperative patient at risk of dislodging life-sustaining device (e.g., ECMO cannula, fresh tracheostomy)

— Psychiatric patient with acute homicidal/suicidal behavior unresponsive to verbal de-escalation

— Documented failure or inappropriateness of alternatives

— Specific behavior described (e.g., "pulling at femoral arterial line") — not vague labels like "uncooperative"

— Physician/LIP order with type, duration, and clinical justification

Definition: Any manual method, physical/mechanical device, material, or equipment that immobilizes or reduces the ability of a patient to move arms, legs, body, or head freely. Chemical restraint = medication used to manage behavior that is not standard treatment for the patient's condition.

Two regulatory categories (CMS/Joint Commission):

Core principle: Restraints are a last resort, time-limited intervention used only when less restrictive alternatives have failed or are clearly inadequate, and only to address a specific clinical safety concern — never for staff convenience, punishment, coercion, or as a substitute for adequate staffing.

When to consider on Step 3:

Required elements before initiation:

Board pearl: A PRN ("as needed") restraint order is never acceptable under CMS — each episode requires a new individualized order based on current assessment. A standing "restrain if agitated" order will be the wrong answer.

Step 3 management: When the stem describes restraint use, your first question is always "Were less restrictive alternatives attempted and documented?" — if not, that is the next best step before placing restraints.

Presentation Patterns and Key History

— ICU delirium: Mechanically ventilated patient, hyperactive subtype, pulling at ETT — classic vignette

— Postoperative hypoactive-to-hyperactive delirium: Elderly hip fracture patient POD#2, sundowning, climbing out of bed

— Substance withdrawal: Alcohol withdrawal with hallucinations and combativeness despite CIWA-guided benzodiazepines

— Acute psychosis or mania: Threatening staff, throwing objects, refusing oral medications

— Dementia with behavioral disturbance: Wandering, exit-seeking in a hospitalized patient with Alzheimer disease

— Baseline cognition and functional status (collateral from family critical in elderly)

— Medication review: anticholinergics, benzodiazepines, opioids, steroids, fluoroquinolones — common deliriogenic agents

— Substance use: alcohol, benzodiazepine, opioid timing of last use

— Recent infections, metabolic derangements, urinary retention, constipation, pain — the reversible "delirium 6"

— Prior history of restraint use, trauma history, PTSD — restraints can re-traumatize survivors of abuse

— Restraints treat behavior, not etiology — always pursue the cause in parallel

— A patient who is hypoxic, hypoglycemic, or in urinary retention should have those fixed, not be tied down

— Check for documented preferences against restraint

— Notify family/surrogate when restraints initiated (required by many institutions)

High-risk clinical scenarios that drive restraint questions:

History elements that must be obtained or reviewed before restraint:

Identify the underlying driver:

Advance directives and surrogate input:

Key distinction: Agitation due to unmet need (pain, full bladder, hypoxia, hypoglycemia, fear) is reversible and should not be the first indication for restraint. Agitation with imminent harm potential despite addressing reversible causes is when restraints become defensible.

Board pearl: In a vignette where a delirious elderly patient is "pulling at IV" — the next best step is usually NOT restraints but rather workup for delirium cause (UA, labs, med review) plus non-pharmacologic measures (family at bedside, reorientation, sitter).

Behavioral and Physical Assessment Before Restraint

— Vital signs: tachycardia, fever (sepsis, withdrawal, NMS, serotonin syndrome, thyroid storm), hypoxia, hypoglycemia

— Glucose fingerstick — non-negotiable in any altered patient

— Pulse oximetry and capnography if obtunded

— Neurologic exam: focal deficits suggest stroke or structural lesion, not primary behavioral problem

— Pupils: pinpoint (opioids), dilated (anticholinergic, sympathomimetic, withdrawal)

— Skin: diaphoresis (withdrawal, sympathomimetic), dry/flushed (anticholinergic)

— Abdomen/bladder scan: urinary retention or fecal impaction is a frequent reversible agitation cause in elderly

— RASS (Richmond Agitation-Sedation Scale): −5 (unarousable) to +4 (combative); target 0 to −2 in most ICU patients

— CAM-ICU or 4AT: detect delirium in nonverbal/ventilated patients

— BARS (Behavioral Activity Rating Scale): ED agitation

— Prone restraint and four-point restraint risk positional asphyxia, especially with obesity, recent meal, intoxication

— Struggle against restraints causes rhabdomyolysis, hyperthermia, lactic acidosis, sudden cardiac death — particularly with stimulant intoxication or excited delirium

— Airway patent, no aspiration risk in chosen position

— No fracture, recent surgical site, vascular access, or wound under restraint

— Circulation distal to limb restraints assessed (cap refill, pulse, color)

Targeted assessment in the agitated patient:

Standardized agitation scales (used during and after restraint):

Hemodynamic considerations during restraint:

Pre-restraint physical clearance checklist:

CCS pearl: When you place restraints in a simulated case, simultaneously order: fingerstick glucose, vital signs q15min, continuous pulse ox/telemetry, and a 1:1 sitter or constant observation. Forgetting monitoring is the most common CCS deduction in restraint cases.

Board pearl: Excited delirium with stimulant use + restraint + IM antipsychotic is a classic sudden death vignette — the safer answer often includes benzodiazepines, cooling, and IV fluids rather than escalating restraint.

Less Restrictive Alternatives — The First-Line "Workup"

Environmental modifications:

— Move to quiet, well-lit room near nursing station

— Reduce noise, alarms, overhead pages at night

— Cluster care to allow uninterrupted sleep blocks

— Keep glasses, hearing aids, dentures in place

— Clock and calendar visible; window for day-night cues

Behavioral/relational:

— Family at bedside — single highest-yield intervention in elderly delirium

— 1:1 sitter or patient safety attendant

— Frequent reorientation, calm low-tone communication

— De-escalation techniques: maintain space, offer choices, validate emotion

— Music therapy, familiar objects from home

Physiologic optimization (treat the cause):

— Pain control (scheduled acetaminophen often underused)

— Toileting schedule, bladder scan, disimpaction

— Hydration, electrolyte correction

— Oxygen if hypoxic; review and deprescribe deliriogenic medications (Beers criteria)

— Restore sleep-wake cycle; minimize nighttime vitals if stable

Device-protection alternatives (medical-surgical setting):

— Mittens (least restrictive — often not classified as restraint if patient can remove)

— Abdominal binder over surgical drains

— Camouflage IV lines under stockinette

— Early extubation/line removal when clinically appropriate

— Tube placement behind ear or in less accessible location

Non-pharmacologic alternatives must be attempted and documented first (except in true imminent-danger emergencies):

Step 3 management: In a hospitalized elderly patient with hyperactive delirium, the best initial management is almost always the HELP (Hospital Elder Life Program) bundle: reorientation, early mobilization, sleep protocol, vision/hearing aids, hydration — before any restraint or antipsychotic.

Board pearl: Mittens that the patient can remove independently are generally not considered restraints; mittens secured to the bed are restraints. Know this distinction.

Pharmacologic Alternatives and Adjuncts

Hyperactive delirium in older medical/surgical patients:

— Low-dose haloperidol 0.25–0.5 mg PO/IV/IM — preferred when antipsychotic needed; check baseline QTc

— Quetiapine 12.5–25 mg PO — useful when QT prolongation concern or Parkinson disease/Lewy body (avoid haloperidol in these)

— Avoid benzodiazepines in non-withdrawal delirium — they worsen confusion (exception: alcohol/benzo withdrawal)

— Antipsychotics carry FDA black box warning for increased mortality in elderly dementia patients — use lowest dose, shortest duration, document risk-benefit

Alcohol or benzodiazepine withdrawal:

— Benzodiazepines first-line — lorazepam, diazepam, or chlordiazepoxide via CIWA-Ar protocol

— Phenobarbital alternative in refractory cases

— Thiamine 100 mg before glucose to prevent Wernicke

Acute psychiatric agitation (psychosis, mania):

— Oral preferred when accepted: olanzapine ODT, risperidone, haloperidol

— IM if refusing/imminent danger: haloperidol 5 mg + lorazepam 2 mg + diphenhydramine 50 mg ("B-52") — though many institutions now favor olanzapine 10 mg IM or droperidol 5 mg IM

— Avoid IM olanzapine + parenteral benzodiazepine concurrently — respiratory depression and hypotension risk

ICU sedation (alternative to restraint in ventilated patients):

— Dexmedetomidine preferred for delirium reduction over benzodiazepine infusions

— Daily sedation interruption (SAT/SBT bundle) reduces both restraint days and ICU LOS

Pharmacologic management of agitation is not a substitute for treating the underlying cause but may reduce or avoid physical restraint.

Key distinction: A medication given at usual therapeutic dose for a diagnosed condition (e.g., haloperidol for schizophrenia) is not a chemical restraint. The same medication given to a non-psychotic delirious patient solely to control behavior is a chemical restraint and triggers monitoring requirements.

Board pearl: Get a baseline ECG before haloperidol if feasible; QTc >500 ms is a contraindication.

Indications and Decision Logic for Initiating Restraints

— Specific imminent risk of physical harm to patient or others

— Less restrictive alternatives attempted, failed, or clearly inadequate given urgency

— Restraint is expected to address the specific risk

— Use is time-limited with a clear plan for discontinuation

— Staff convenience or insufficient staffing

— Punishment or retaliation

— Coercion to gain cooperation with non-emergent care

— Routine for "fall risk" alone — restraints do not reduce falls and increase fall-related injury

— As substitute for monitoring

— Routinely for all confused or wandering patients

— Step 1: Identify and treat reversible causes (hypoxia, hypoglycemia, pain, retention, withdrawal, infection)

— Step 2: Apply non-pharmacologic alternatives (family, sitter, environment)

— Step 3: Consider targeted pharmacotherapy if behavior persists with safety risk

— Step 4: If imminent harm remains, initiate least restrictive restraint type for shortest duration

— Step 5: Continuously reassess for earliest discontinuation

— Violent/self-destructive: physician/LIP order, in-person evaluation within 1 hour; order limited to 4 hours adults, 2 hours ages 9–17, 1 hour <9 years; renewable up to 24 hours

— Non-violent (medical): order valid up to 24 hours, must be renewed daily with in-person reassessment

— Never PRN; each episode = new order

Justifiable indications (must meet ALL):

NEVER acceptable indications (always wrong answer):

Decision tree:

Order requirements (CMS):

Step 3 management: When a CCS case escalates to restraints, place the order with: type (e.g., bilateral soft wrist), clinical indication (e.g., "pulling at endotracheal tube"), duration, monitoring frequency, and criteria for discontinuation ("when extubated or following commands").

Board pearl: Fall prevention is not an indication for restraint — bed alarms, low beds, hip protectors, and sitters are correct answers.

Types of Restraints and Selection of Least Restrictive Option

Least restrictive:

— Mittens (unsecured): prevent line manipulation; patient retains limb mobility

— Lap belt or seated waist belt that patient can release: positioning aid, not restraint

— Bed rails: all 4 raised = restraint; partial rails for mobility assistance ≠ restraint

Moderately restrictive:

— Soft wrist restraints (single or bilateral): most common medical-surgical; allow some hand mobility

— Soft ankle restraints: added when kicking or attempting to climb out

— Mitts secured to bed

Most restrictive:

— Four-point leather/locking restraints: reserved for violent behavior with imminent danger; psychiatric/ED settings

— Five-point (adds chest/torso strap): highest risk of positional asphyxia

— Seclusion: involuntary confinement alone in a room from which patient cannot exit

Application principles:

— Quick-release knots to bed frame (not side rail, which moves)

— Two fingers should fit between restraint and skin

— Limbs in anatomic neutral position; avoid abduction >90°

— Supine preferred over prone to reduce asphyxia risk

— Head of bed elevated 30° to reduce aspiration

Special restraint types:

— Enclosed bed (Posey bed): alternative for wandering dementia; classified as restraint

— Geri-chair with locked tray: restraint if patient cannot remove

— Chemical restraint: as above

Hierarchy from least to most restrictive:

Key distinction: Seclusion and restraint are governed by similar but distinct CMS rules; seclusion is only permitted for management of violent or self-destructive behavior, never for medical-surgical indications.

Board pearl: Match restraint to behavior — a confused patient pulling at one IV does not need four-point restraints; bilateral soft wrist mitts or a single wrist restraint may suffice. Choosing the least restrictive effective option is the right answer.

Application Procedure and CCS-Style Order Set

— Confirm physician order with indication, type, duration

— Two-staff minimum for application of violent restraints; security/code grey team if needed

— Explain to patient and family in calm terms, even if patient cannot fully comprehend

— Remove jewelry, watches, sharps from patient

— Document time zero, behavior necessitating restraint, alternatives tried

— Position supine, head elevated; avoid prone

— Soft padded restraint between cuff and skin

— Secure to bed frame, never to side rail or movable part

— Confirm distal pulses, cap refill, sensation, motor function immediately

— Restraint type and limbs specified

— Clinical indication documented

— Vital signs q15 min × 1 hr, then q1h (more frequent for violent)

— Continuous pulse oximetry and telemetry

— Circulatory/neurovascular checks q15 min (skin integrity, pulses, ROM)

— Range of motion to each restrained limb q2h, one limb at a time

— Repositioning, toileting offered q2h

— Food, fluid offered at meals and q2h

— 1:1 observation for violent restraint or seclusion

— Reassessment for discontinuation at minimum q1h (violent) or q4h (non-violent)

— Notify family/surrogate

— Continue workup for underlying cause (labs, imaging, medication review)

— Schedule debrief with patient and team after release

Pre-application:

During application:

Standing CCS order set when placing restraints:

One-hour face-to-face requirement (violent restraint): Physician, advanced practice provider, or trained RN (varies by state/institution) must evaluate within 1 hour to assess physical/psychological status, continued need, and complications.

CCS pearl: Forgetting q2h repositioning and ROM, q15 min circulation checks, or 1-hour face-to-face for violent restraint are the most common CCS scoring losses. Build a "restraint bundle" macro.

Board pearl: Document discontinuation criteria at the time of order — e.g., "Discontinue when patient follows commands and denies intent to remove lines." This shifts the burden toward release.

Special Populations — Elderly and Renal/Hepatic Impairment

— Highest restraint use and highest harm rates

— Pressure injury, deconditioning, functional decline, incontinence, aspiration, delirium prolongation, and death are documented restraint complications

— Skin fragility — increased risk of skin tears, bruising, abrasions under restraint

— Antipsychotic black box warning: increased mortality (cerebrovascular events, sudden death) in elderly dementia patients

— Beers Criteria: avoid benzodiazepines, anticholinergics, first-generation antihistamines for behavioral control in elderly

— Prefer non-pharmacologic measures + low-dose haloperidol or quetiapine if pharmacotherapy required

— Hip fracture, hospitalization, and ICU admission are independent restraint risks — proactive delirium prevention bundle (HELP) reduces use

— Haloperidol: no dose adjustment but accumulates with severe impairment — start lowest dose

— Risperidone: reduce dose 50% if CrCl <30

— Olanzapine: no renal adjustment

— Lorazepam, oxazepam, temazepam preferred benzodiazepines in CKD (glucuronidated, no active metabolites)

— Avoid diazepam, chlordiazepoxide in CKD — active metabolite accumulation

— Watch for uremic encephalopathy masquerading as agitation — treat with dialysis, not restraint

— Lorazepam, oxazepam, temazepam ("LOT") preferred — phase II metabolism unaffected

— Avoid diazepam, midazolam, chlordiazepoxide — prolonged sedation

— Haloperidol: reduce dose; monitor for extrapyramidal effects

— Hepatic encephalopathy — agitation is from ammonia, not behavioral — treat with lactulose, rifaximin; restraint is rarely correct answer

Elderly patients:

Renal impairment:

Hepatic impairment:

Step 3 management: In an elderly hospitalized patient with new agitation, the best next step is a delirium workup (CAM, UA, labs, med reconciliation) and non-pharmacologic interventions, NOT initiation of antipsychotics or restraints.

Key distinction: Sundowning alone in a stable demented patient = environmental measures and reassurance. Acute change in mentation = delirium workup. Don't restrain either as first-line.

Special Populations — Pediatrics, Pregnancy, Psychiatric, and Disability

— Stricter CMS time limits: violent restraint orders ≤2 hours ages 9–17, ≤1 hour <9 years

— Face-to-face evaluation within 1 hour required

— Parental notification required as soon as possible

— Developmental considerations: explain in age-appropriate language; allow caregiver presence when safe

— Autism spectrum/intellectual disability: sensory accommodations (weighted blanket, dim lighting), preferred communication methods preferred over restraint

— Highest legal scrutiny — schools and inpatient pediatric units are common litigation sites

— Avoid supine position in late pregnancy — risk of aortocaval compression; use left lateral tilt

— Avoid abdominal/torso straps in 2nd/3rd trimester

— Haloperidol generally safe; benzodiazepines associated with neonatal withdrawal if used near delivery

— Incarcerated pregnant patients: many states prohibit shackling during labor — know that this exists

— Trauma-informed care principles — many patients have abuse histories; restraint can re-traumatize

— Advance psychiatric directives may specify preferred de-escalation strategies and avoid certain medications

— Patients with capacity may refuse pharmacotherapy but lose that right when imminent danger threshold met

— Post-restraint debriefing with patient is required practice — explore triggers, alternatives for next episode

— Communication boards, sign language interpreters, AAC devices before assuming agitation is behavioral

— Wheelchair-bound patients: lap belts they cannot release = restraint

— Deaf/hard of hearing: agitation may reflect inability to communicate — provide interpreter first

— Higher risk of positional asphyxia in prone or supine with chest straps

— Standard restraints may not fit — use bariatric-rated equipment

Pediatric considerations:

Pregnancy:

Psychiatric population:

Patients with disability:

Bariatric patients:

Board pearl: In an incarcerated woman in active labor, removing shackles is the right answer — federal Bureau of Prisons and most state laws prohibit restraint during labor and delivery except in extraordinary circumstances.

Step 3 management: In pediatric restraint, parental presence at the bedside is both therapeutically and legally critical — call the family early.

Complications and Adverse Outcomes

— Positional asphyxia — leading cause of restraint-associated death, especially prone position, obesity, intoxication, large meal

— Sudden cardiac death — particularly in excited delirium/stimulant intoxication during struggle

— Strangulation — vest/torso restraints; banned in many institutions

— Aspiration pneumonia — supine positioning, sedation, vomiting

— Skin breakdown, pressure injuries, nerve compression (radial nerve palsy from wrist restraint)

— Rhabdomyolysis from prolonged struggling — check CK, urine myoglobin

— Brachial plexus injury, joint dislocations from struggle against restraint

— DVT/PE from immobility — chemical VTE prophylaxis warranted

— Bowel/bladder dysfunction — urinary retention, constipation, incontinence

— Strangulation by bed rails — entrapment in gaps; FDA reporting required

— Hypothermia or hyperthermia depending on environment

— Dehydration if not actively offered fluids

— Malnutrition with prolonged use

— Disuse atrophy and contractures with multi-day restraint

— Acute traumatic stress and PTSD, especially in survivors of prior trauma or assault

— Worsening agitation and paranoia

— Loss of trust in healthcare system — future care avoidance

— Delirium prolongation — restraints are an independent risk factor

— Haloperidol: QT prolongation, torsades, EPS, NMS, akathisia (paradoxically worsens agitation)

— Benzodiazepines: respiratory depression, paradoxical disinhibition (children, elderly, brain injury)

— Combined IM antipsychotic + benzodiazepine: hypotension, oversedation, aspiration

— Increased length of stay

— Increased fall-related injury (paradoxical)

— Litigation and regulatory citations

Physical complications:

Physiologic and metabolic:

Psychological complications:

Medication-associated complications when chemical restraint used:

System-level harms:

Sentinel event reporting: Death or major injury associated with restraint use is a Joint Commission sentinel event — mandatory root cause analysis (RCA).

CCS pearl: Order DVT prophylaxis, repositioning q2h, and skin assessments as part of the restraint bundle to prevent complications.

Board pearl: Any death while a patient is in restraint — regardless of apparent cause — is CMS-reportable within 1 working day (and within 24 hours for soft 2-point wrist restraint deaths).

When to Escalate Care — Consultation and Higher Level of Monitoring

Medical escalation:

— Underlying cause unclear or refractory — ICU transfer for closer monitoring, advanced workup

— Hemodynamic instability during restraint episode

— Severe hyperthermia, rhabdomyolysis, or excited delirium syndrome — ICU-level cooling, IV fluids, sedation

— Respiratory compromise from positioning or chemical restraint

— Status epilepticus masquerading as agitation — neurology consult, EEG

Behavioral escalation:

— Psychiatry consult for any inpatient who requires violent-category restraint, repeated PRN antipsychotics, or seclusion

— Persistent agitation despite first-line pharmacotherapy

— Suicidal ideation, command hallucinations, or homicidal threats

— Consideration of involuntary psychiatric hold (state-specific: 72-hour holds, 5150 in CA, "petition" in others)

Geriatrics/delirium escalation:

— Geriatrics consult or delirium service in refractory hyperactive delirium

— Palliative care if restraints conflict with comfort-focused goals

Ethics consult:

— Conflict between family and team regarding restraint use

— Patient with capacity refusing restraint when team feels it is needed (rare — capacity usually impaired)

— Long-term restraint use in chronically institutionalized patients

Security/code grey activation:

— Imminent staff injury risk

— Weapons or unexpected violence

— Multiple staff required for safe application

— Restraints generally must be reordered upon transfer between units (e.g., ED to floor)

— Handoff communication: type, duration of use, attempted alternatives, response, monitoring plan, discontinuation criteria

Escalate when restraint is being considered or has been initiated and:

Transfer of care considerations:

Step 3 management: A patient requiring >24 hours of continuous restraint despite escalating interventions warrants formal multidisciplinary case review — psychiatry, primary team, nursing, ethics, social work — to identify a path off restraints.

Board pearl: Excited delirium with stimulant intoxication is a medical emergency — call for ICU evaluation, give IV fluids and benzodiazepines, cool actively, and minimize struggle; restraint alone risks sudden death.

Differential Diagnosis of Agitation — Medical Causes (Same-Category)

The "I WATCH DEATH" delirium mnemonic categories:

— Infection: UTI (especially elderly), pneumonia, meningitis, encephalitis, sepsis, COVID

— Withdrawal: alcohol, benzodiazepine, opioid (less commonly causes delirium), nicotine

— Acute metabolic: hyponatremia, hypernatremia, hypoglycemia, hyperglycemia, hypercalcemia, uremia, hepatic encephalopathy, hypomagnesemia

— Trauma: head injury, subdural hematoma (elderly fall), fat embolism

— CNS pathology: stroke (especially right MCA, frontal), seizure (postictal, NCSE), tumor, abscess

— Hypoxia/hypercapnia: PE, pneumonia, COPD exacerbation, CHF

— Deficiencies: thiamine (Wernicke), B12, folate, niacin

— Endocrinopathies: thyroid storm, myxedema madness, Cushing, Addisonian crisis, pheochromocytoma

— Acute vascular: hypertensive encephalopathy, vasculitis, cerebral venous thrombosis

— Toxins/medications: anticholinergics (TCAs, antihistamines, antispasmodics), steroids, fluoroquinolones, opioids, benzodiazepines, serotonin syndrome, NMS, lithium toxicity, digoxin toxicity

— Heavy metals: lead, mercury

— Hypoglycemia — combative, diaphoretic, tachycardic patient → fingerstick first, always

— Hypoxia/hypercapnia — restless ICU patient → check ABG, not restraints

— Urinary retention/fecal impaction — agitation in elderly nursing home patient → bladder scan, rectal exam

— Non-convulsive status epilepticus — fluctuating mental status with subtle automatisms → EEG

— Nondominant hemisphere stroke — agitation, neglect, anosognosia

— Hepatic encephalopathy — asterixis, elevated ammonia

— Wernicke encephalopathy — confusion + ophthalmoplegia + ataxia in alcohol use disorder

Before attributing behavior to a primary psychiatric diagnosis, rule out medical causes — restraints applied to undiagnosed medical illness are a sentinel error.

Specific high-yield medical mimics:

Key distinction: A patient with acute change in mental status has delirium until proven otherwise; chronic baseline confusion suggests dementia. Both deserve workup, not reflexive restraint.

Board pearl: A previously oriented elderly inpatient who becomes acutely agitated overnight needs UA, CXR, labs, and medication review before antipsychotics or restraints — the most likely cause is occult infection or medication effect.

Differential Diagnosis — Primary Psychiatric and Behavioral Causes

Primary psychiatric:

— Acute psychosis (schizophrenia, schizoaffective): hallucinations, delusions, disorganized thought — antipsychotic first-line; restraint only if imminent danger

— Bipolar manic episode: pressured speech, grandiosity, decreased need for sleep — mood stabilizer + antipsychotic; consider involuntary hold

— Major depression with agitation: akathisia-like restlessness — careful pharmacotherapy

— Borderline personality disorder crisis: self-harm, splitting — verbal de-escalation, DBT skills, avoid restraint when possible as it reinforces dysregulation

— PTSD flashback: trauma-informed grounding techniques; restraint highly counterproductive

— Panic attack: hyperventilation, derealization — reassurance, breathing, not restraint

— Catatonia (excited type): rigidity alternating with agitation — benzodiazepine challenge (lorazepam 1–2 mg), ECT; antipsychotics may worsen

Substance-related:

— Alcohol withdrawal/delirium tremens: autonomic hyperactivity, tremor, hallucinations — benzodiazepines, thiamine; restraint as bridge only

— Sympathomimetic intoxication (cocaine, methamphetamine, MDMA): hyperthermia, hypertension, mydriasis — benzodiazepines, cooling, IV fluids; restraint risks sudden death

— Hallucinogen intoxication (PCP, ketamine, LSD): dissociation, agitation — quiet environment, benzodiazepines

— Cannabis/synthetic cannabinoid: anxiety, paranoia — supportive

— Anticholinergic toxicity: "mad as a hatter" — physostigmine in selected cases

— Serotonin syndrome / NMS: discontinue offending agent, supportive care, cyproheptadine or dantrolene

Behavioral/developmental:

— Intellectual disability / autism with sensory overload

— Traumatic brain injury with disinhibition

— Dementia with behavioral disturbance — non-pharm first

Once medical causes are excluded or addressed, primary psychiatric and behavioral conditions present with agitation requiring distinct approaches.

Key distinction: Catatonia can present as either stupor or excited agitation — antipsychotics worsen catatonia; lorazepam is diagnostic and therapeutic. Missing this and restraining + giving haloperidol is a classic wrong answer.

Board pearl: Sympathomimetic-induced excited delirium → benzodiazepines + cooling + IVF, NOT antipsychotics; physical restraint alone has well-documented sudden-death cases.

Discontinuation, Documentation, and Transition Planning

— Reassess at each monitoring interval — does the original behavior still pose imminent risk?

— Trial release of one limb at a time when behavior improving

— Document specific behavioral criteria for discontinuation in initial order

— "Follows commands, denies intent to remove lines"

— "Calm cooperative behavior × 2 hours"

— "RASS 0 to −1, no agitation × 4 hours"

— "Underlying cause (hypoxia, hypoglycemia, infection) corrected"

— Behavior necessitating restraint (specific, observable)

— Less restrictive alternatives attempted and outcomes

— Type, location, time of application

— Patient and family notification

— Vital signs, neurovascular checks, ROM, hygiene, nutrition documented per protocol

— Face-to-face evaluation findings

— Time of discontinuation and patient status

— Post-restraint debrief with patient (when able) and team

— What triggered the behavior?

— What worked / what didn't?

— Patient preferences for future episodes (psychiatric advance directive)

— Staff well-being check

— Add to problem list and care plan: triggers, effective de-escalation strategies, medication preferences

— Communicate at handoff to next shift, next unit, next facility

— Inform PCP at discharge

— Address underlying cause (e.g., dementia diagnosis, substance use disorder treatment referral)

— Caregiver education on home safety, behavioral strategies

— Outpatient psychiatry, geriatrics, or addiction medicine follow-up

— Medication reconciliation — deprescribe deliriogenic agents

— If new behavioral diagnosis: psychoeducation, advance psychiatric directive discussion

Continuous reassessment for earliest possible release:

Discontinuation criteria examples:

Documentation required for every restraint episode:

Post-event debrief content:

Care plan updates:

Discharge considerations after hospitalization involving restraint:

Step 3 management: A patient released from restraints should remain on close behavioral observation with continued treatment of the underlying cause; restart restraints only if the original criteria are met again — do not automatically continue "as a precaution."

Board pearl: "Trial off restraints" is the right answer earlier than most learners think — staying in restraints longer than necessary is itself a deviation from standard of care.

Follow-Up, Monitoring Parameters, and Rehabilitation

— Non-violent/medical restraint: circulation, ROM, hygiene, toileting, nutrition, hydration q2h; restraint reassessment q4h; physician renewal q24h

— Violent restraint: continuous 1:1 observation; q15 min circulation/safety checks; physician face-to-face within 1 hour; reassessment for renewal q4h (adults), q2h (ages 9–17), q1h (<9)

— Continuous pulse oximetry and telemetry while in violent restraint or after IM sedation

— Physical therapy for deconditioning, contracture prevention — especially after prolonged or multi-episode use

— Occupational therapy for ADL retraining

— Speech/swallowing evaluation if aspiration risk during episode

— Skin care for breakdown sites

— DVT prophylaxis continued through mobilization

— Cognitive rehabilitation if post-delirium cognitive impairment

— PCP follow-up within 1–2 weeks for medication reconciliation, delirium recovery assessment

— Geriatric assessment in elderly — cognition, function, home safety, caregiver burden

— Psychiatry follow-up within 1–2 weeks for psychiatric admissions

— Addiction medicine referral for substance-related agitation episodes

— Cognitive assessment at 1 and 3 months — post-ICU and post-delirium cognitive impairment can persist

— Trauma-focused therapy if patient reports restraint-related distress

— Educate patient and family about delirium risk and reversibility

— Advance care planning discussion — preferences regarding future restraints, intubation, ICU

— Psychiatric advance directive (PAD) drafting for patients with recurrent psychiatric crises

— Caregiver training on home behavioral management for dementia

— Track restraint hours per 1000 patient-days as a quality indicator

— Unit-level review of all violent restraint episodes

— Annual staff training in de-escalation (CPI, Handle With Care, BERT)

Acute monitoring during restraint (summary):

Post-restraint rehabilitation needs:

Outpatient follow-up after hospitalization with restraint use:

Counseling and prevention:

Quality and system-level metrics:

CCS pearl: Schedule a 2-week post-discharge visit with the PCP and document medication reconciliation, delirium screening (e.g., 4AT), and functional reassessment — this is the high-yield ambulatory follow-up.

Board pearl: Post-ICU syndrome includes cognitive, psychiatric, and physical impairment — patients restrained during ICU stays are at increased risk and warrant proactive follow-up.

Ethical, Legal, and Patient Safety Considerations

— Autonomy vs. beneficence/non-maleficence — restraints restrict autonomy to prevent harm

— Justice — restraints are disproportionately used in racial/ethnic minority patients, patients with limited English proficiency, and those with psychiatric diagnoses; this is a quality and equity issue

— Least restrictive alternative is an ethical and legal mandate

— In emergency with imminent harm, consent is not required to apply restraints (emergency exception to consent)

— Outside emergency, patient or surrogate notification required as soon as feasible

— Restraint use should be disclosed in the medical record and to family/surrogate

— Capacity to refuse restraint is rare in the agitated patient — but capacity should still be assessed and documented

— CMS Conditions of Participation 42 CFR §482.13 — federal standard for all Medicare-participating hospitals

— Joint Commission Standards PC.03.05 — accreditation requirements

— State laws add additional protections (e.g., shackling during labor bans, school restraint laws, psychiatric advance directives)

— HIPAA — restraint events documented but disclosure to family follows usual rules

— EMTALA — emergency restraint use in ED falls under federal emergency stabilization requirements

— Death during or shortly after restraint: report to CMS within 1 working day (and within 24 hours under some criteria)

— Sentinel events to Joint Commission — death or permanent harm

— Suspected elder abuse, child abuse, or abuse of vulnerable adult if inappropriate restraint use observed in long-term care or home — mandated reporter requirements apply

— Restraint status, type, indication, and discontinuation criteria must be communicated at every handoff — failure to do so is a top patient safety failure

— Discharging a patient still requiring behavioral interventions without arranging follow-up creates readmission and harm risk

— Transferring from ED to inpatient psychiatric facility: restraints typically must be reassessed and reordered

— Wrong: a sleeping patient left in restraints after agitation resolved

— Wrong: PRN "as needed" restraint orders

— Wrong: restraint for "fall prevention" alone

— Right: time-limited, indication-specific, monitored restraint with documented alternatives

High-Yield Associations and Rapid-Fire Clinical Facts

— Violent restraint orders: 4h adults, 2h ages 9–17, 1h <9y; renewable to 24h total

— Non-violent restraint orders: 24h, renewed daily

— Face-to-face evaluation: within 1 hour for violent restraint or seclusion

— PRN restraint orders prohibited

— Specific behavior (not "agitated")

— Alternatives tried

— Type, duration, monitoring plan

— Discontinuation criteria

— Report to CMS within 1 working day

— All restraint-associated deaths = Joint Commission sentinel event → RCA mandatory

— Restraints do NOT prevent falls

— Restraints increase fall-related injury severity

— Supine head-elevated preferred

— Prone restraint associated with positional asphyxia deaths

— Left lateral tilt in pregnancy

— Avoid benzodiazepines in non-withdrawal delirium

— Avoid haloperidol in Parkinson disease, Lewy body dementia, QTc >500

— Catatonia: lorazepam first, avoid antipsychotics

— Excited delirium with stimulants: benzodiazepines + cooling + IVF, avoid IM antipsychotic alone

— Unsecured mittens patient can remove = not restraint

— Mittens tied to bed = restraint

— All 4 raised = restraint

— Partial rails for mobility aid = not restraint

— Medication used to control behavior not part of standard treatment for the patient's diagnosis

— Pregnant incarcerated patients in labor — shackling prohibited in most jurisdictions

— Elderly + antipsychotic = black box mortality warning

— Pediatric restraint = strictest time limits and parental notification

— HELP bundle (Hospital Elder Life Program) — reduces delirium and restraint use

— ABCDEF ICU bundle (Awakening, Breathing trials, Choice of sedation, Delirium monitoring, Early mobility, Family engagement) — reduces ICU restraint days

— Dexmedetomidine > benzodiazepines for ICU delirium prevention

— Family presence — single highest-impact non-pharmacologic intervention

Board Question Stem Patterns

"An 82-year-old man is hospitalized for pneumonia. On hospital day 2, he pulls out his IV and tries to climb out of bed. He calls the nurse his deceased wife." → Best next step: delirium workup (UA, glucose, oxygenation, med review) + non-pharmacologic measures (reorientation, family at bedside, sitter). Not restraints, not lorazepam.

"Nursing requests a PRN order for soft wrist restraints in case the patient becomes agitated overnight." → Correct response: PRN restraint orders are prohibited; orders must be specific to each episode of behavior.

"An 88-year-old with dementia has fallen twice. The team considers bilateral wrist restraints." → Best answer: bed alarms, low bed, hip protectors, sitter, scheduled toileting — not restraints (do not reduce falls; increase injury).

"A 28-year-old male, agitated, diaphoretic, T 40°C, HR 140 after cocaine use, is restrained prone and given IM haloperidol; he becomes unresponsive." → Lesson: avoid prone restraint and IM antipsychotic alone; use benzodiazepines, IV fluids, active cooling.

"Young woman with rigid posturing alternating with excited agitation, mutism." → Lorazepam challenge, not antipsychotic + restraint.

"Hospital day 3, post-op patient becomes tremulous, diaphoretic, hallucinating." → CIWA-guided benzodiazepines + thiamine; restraint only if needed to bridge.

"A 10-year-old in inpatient psychiatry requires violent restraint." → Order time limit 2 hours, face-to-face within 1 hour, parental notification as soon as possible.

"Patient found pulseless 30 minutes after being placed prone in 4-point restraints." → Positional asphyxia; report as sentinel event; CMS notification within 1 working day.

"Patient now calm, oriented, cooperative for 4 hours." → Remove restraints; do not continue "in case."

"Family refuses consent for restraint in imminently dangerous demented patient." → Emergency exception allows restraint without consent when imminent harm; notify family as soon as feasible.

Pattern 1 — Elderly delirium:

Pattern 2 — PRN restraint order:

Pattern 3 — Fall prevention:

Pattern 4 — Excited delirium with stimulant:

Pattern 5 — Catatonia mistaken for psychosis:

Pattern 6 — Alcohol withdrawal:

Pattern 7 — Pediatric restraint:

Pattern 8 — Restraint complication:

Pattern 9 — Discontinuation:

Pattern 10 — Capacity/consent:

Board pearl: When unsure, the lowest-restriction answer that addresses the underlying cause is almost always correct.

One-Line Recap

Restraints are a last-resort, time-limited safety intervention used only after less restrictive alternatives fail, requiring individualized orders, intensive monitoring, and continuous reassessment for the earliest possible discontinuation — while always pursuing the underlying medical or behavioral cause.

Indications: Specific imminent risk of harm to self/others after alternatives attempted; never for staff convenience, punishment, fall prevention alone, or via PRN order.

Alternatives first: Treat reversible causes (hypoxia, hypoglycemia, pain, retention, infection, withdrawal, deliriogenic medications) → non-pharmacologic measures (family at bedside, sitter, reorientation, sleep protocol, HELP/ABCDEF bundles) → targeted pharmacotherapy (low-dose haloperidol or quetiapine for delirium, benzodiazepines for withdrawal and excited delirium with stimulants, dexmedetomidine for ICU sedation).

Orders and monitoring: Specific behavior documented, type and duration limited (violent: 4h adult/2h teen/1h child; non-violent: 24h), face-to-face within 1 hour for violent restraint, continuous observation, q15 min neurovascular checks, q2h ROM/toileting/hygiene, daily renewal with reassessment, clear discontinuation criteria, family notification, post-event debrief.

Safety and ethics: Avoid prone position (positional asphyxia), avoid IM antipsychotic monotherapy in stimulant-induced excited delirium, avoid antipsychotics in catatonia and Parkinson/Lewy body, avoid benzodiazepines in non-withdrawal delirium; report restraint-associated deaths to CMS within 1 working day as Joint Commission sentinel events; monitor for inequities in restraint use across race, language, and psychiatric diagnosis.

Board reflex: The right answer almost always decreases restriction, increases monitoring, addresses the underlying cause, and engages family and multidisciplinary support.
