Management of Agitation in an Elderly Patient New to a Locked Unit
For an elderly patient newly admitted to a locked unit exhibiting agitation and exit-seeking behavior, immediately implement non-pharmacological interventions focusing on orientation, environmental modification, and systematic investigation of reversible medical causes—reserving low-dose haloperidol (0.5-1 mg) only for severe agitation with imminent risk of harm after behavioral approaches have failed. 1
Immediate Priority: Address Reversible Medical Causes
The first critical step is systematically investigating underlying medical triggers that commonly drive agitation in elderly patients who may be unable to verbally communicate discomfort:
- Pain assessment and management is a major contributor to behavioral disturbances and must be addressed immediately 1
- Screen for infections, particularly urinary tract infections and pneumonia, which are common triggers in this population 2, 1
- Check for urinary retention and constipation, both of which significantly contribute to agitation 2, 1
- Assess for dehydration and electrolyte disturbances 3
- Review all medications to identify anticholinergic agents (diphenhydramine, oxybutynin, cyclobenzaprine) that worsen agitation and cognitive function 1
Non-Pharmacological Interventions (First-Line Treatment)
These interventions have substantial evidence for efficacy without the mortality risks associated with pharmacological approaches and must be attempted first 1:
Environmental and Communication Strategies
- Ensure effective communication and orientation: Explain where the patient is, who you are, and your role using calm tones and simple one-step commands 2, 3
- Provide adequate lighting to reduce confusion and fear 2, 3
- Allow adequate time for the patient to process information before expecting a response 1
- Reduce excessive noise and environmental stimuli 1
- Install safety equipment such as grab bars to prevent injuries while allowing safe movement 1
Addressing Exit-Seeking Behavior Specifically
- Explore the patient's concerns and anxieties about being in the new environment 2, 3
- Establish structured daily routines to provide predictability 1
- Consider whether the patient's exit-seeking represents an unmet need (bathroom, hunger, boredom, desire for familiar surroundings) 4
- Provide meaningful activities such as 1-on-1 socializing or food/drink, which have the fewest barriers to implementation 5
Pharmacological Management (Reserved for Severe Cases Only)
Medications should only be used when the patient is severely agitated, threatening substantial harm to self or others, and behavioral interventions have been thoroughly attempted and documented as insufficient. 1
When Pharmacological Treatment Is Indicated
Use medications only in these specific circumstances 1:
- Severe agitation with imminent risk of harm to self or others
- Patient is severely distressed despite non-pharmacological interventions
- Behavioral approaches have been systematically attempted for 24-48 hours and documented as failed
Medication Selection Algorithm
For acute severe agitation:
- Haloperidol 0.5-1 mg orally (maximum 5 mg daily in elderly patients) 2, 1
- Start with 0.5 mg in frail elderly patients 1
- Can be given orally, subcutaneously, or intramuscularly 1
- Monitor for extrapyramidal symptoms and QTc prolongation 1
Alternative for acute agitation if able to swallow:
- Lorazepam 0.25-0.5 mg orally (maximum 2 mg in 24 hours for elderly) 2, 3
- However, benzodiazepines should NOT be first-line for agitated delirium as they increase delirium incidence and duration, and cause paradoxical agitation in approximately 10% of elderly patients 1
For chronic agitation without psychotic features (after stabilization):
- SSRIs are preferred: Citalopram 10 mg/day (maximum 40 mg/day) or Sertraline 25-50 mg/day (maximum 200 mg/day) 1
- Evaluate response within 4 weeks; if no benefit, taper and discontinue 1
Critical Safety Warnings
Before initiating any antipsychotic, you must discuss with the patient (if feasible) and surrogate decision maker 1:
- Increased mortality risk (1.6-1.7 times higher than placebo in elderly dementia patients) 1
- Cardiovascular effects including QT prolongation, dysrhythmias, and sudden death 1
- Risk of falls, hypotension, and metabolic changes 1
- Extrapyramidal symptoms (tremor, rigidity, bradykinesia) 1
Patients over 75 years respond less well to antipsychotics, particularly olanzapine 1
Monitoring and Reassessment
- Evaluate ongoing need daily with in-person examination 1
- Use the lowest effective dose for the shortest possible duration 1
- Monitor for side effects including extrapyramidal symptoms, falls, sedation, metabolic changes, and cognitive worsening 1
- Taper and discontinue as soon as the acute crisis resolves 1
- Avoid inadvertent chronic use—approximately 47% of patients continue receiving antipsychotics after discharge without clear indication 1
Common Pitfalls to Avoid
- Do NOT use antipsychotics for mild agitation or exit-seeking alone—reserve them only for dangerous, severe symptoms 1
- Do NOT use benzodiazepines as first-line for agitated delirium in elderly patients 1
- Do NOT use anticholinergic medications (diphenhydramine) as they worsen agitation and cognitive function 1
- Do NOT continue antipsychotics indefinitely—review need at every visit 1
- Do NOT skip the systematic investigation of medical causes—treating the underlying trigger is more effective than sedation 1
