Can an 82-year-old female patient with a subdural hematoma, urinary tract infection (UTI), and stage 4 lung cancer, currently undergoing immunotherapy, receive treatment for her anxiety?

Management of Anxiety in an 82-Year-Old Cancer Patient with Subdural Hematoma

Yes, this patient can receive treatment for anxiety, but you must first address the underlying medical causes—specifically the UTI and potential delirium from the subdural hematoma—before considering anxiolytic medications, and if pharmacotherapy is needed, use extreme caution with benzodiazepines given her age, head trauma, and high risk of cognitive impairment. 1

Critical First Steps: Rule Out Medical Causes

Before treating anxiety pharmacologically, you must address reversible medical causes that commonly present as restlessness and anxiety in this clinical context: 1

• Treat the UTI aggressively - Urinary tract infections are a primary cause of delirium and agitation in elderly patients, particularly those with subdural hematomas 1
• Assess for delirium - The combination of subdural hematoma, infection (UTI), advanced age, and cancer makes delirium highly likely; restlessness may be delirium rather than primary anxiety 1
• Evaluate for uncontrolled symptoms - Pain, fatigue, and other physical symptoms from cancer or head trauma must be addressed first, as these commonly manifest as anxiety 1
• Check electrolytes - Electrolyte imbalances from cancer, immunotherapy, or infection can cause agitation 1

Non-Pharmacologic Management (Preferred First-Line)

For cancer patients with anxiety, non-pharmacologic interventions should be offered as first-line treatment when feasible: 1

• Provide supportive care and education to the patient and family about anxiety symptoms and what warrants calling the medical team 1
• Ensure safety measures are in place given the subdural hematoma and restlessness to prevent falls 1
• Consider brief psychosocial interventions with relaxation techniques or problem-solving strategies, even in the acute setting 1

Pharmacologic Treatment: When and What to Use

If anxiety persists after addressing medical causes, pharmacotherapy may be offered, but medication selection is critical in this high-risk patient: 1

Benzodiazepines: Use with Extreme Caution

Benzodiazepines carry significant risks in this patient and should be time-limited if used at all: 1

• Major concerns: Cognitive impairment, increased fall risk, respiratory depression, and worsening delirium in elderly patients with head trauma 1
• If prescribed: Use the lowest effective dose for the shortest duration possible, in accordance with psychiatric guidelines 1
• Lorazepam is FDA-approved for short-term relief of anxiety symptoms, but this approval does not negate the heightened risks in your patient 2
• Monitor closely for paradoxical agitation, confusion, or worsening neurological status 1

Alternative Pharmacologic Options

Consider non-benzodiazepine anxiolytics that pose less cognitive risk: 1, 3

• SSRIs or SNRIs may be preferable if anxiety is moderate to severe and treatment duration will extend beyond a few days 3
• Low-dose antipsychotics (neuroleptics) may be appropriate if delirium is contributing to agitation 1
• The choice should be informed by adverse effect profiles, drug interactions with immunotherapy, and the patient's overall medical stability 1

Clinical Algorithm for This Patient

1. Immediately: Treat UTI and assess for delirium; implement fall precautions 1
2. Within 24 hours: Reassess anxiety after infection treatment begins; optimize pain and symptom control 1
3. If anxiety persists: Offer supportive care, education, and non-pharmacologic interventions 1
4. If pharmacotherapy needed: Consider non-benzodiazepine options first; if benzodiazepines are unavoidable, use lowest dose for shortest duration with close monitoring 1, 3
5. Reassess frequently: Monitor for treatment response, adverse effects, and changes in neurological status 1

Critical Pitfalls to Avoid

Do not reflexively prescribe benzodiazepines without first addressing medical causes - this is the most common error and can worsen outcomes in elderly patients with head trauma and infection 1, 4

Do not overlook delirium - restlessness in this clinical context is delirium until proven otherwise, and benzodiazepines can make it worse 1

Do not use long-term benzodiazepines - if started, they must be time-limited and tapered as soon as the acute stressor (infection, acute phase of subdural hematoma) resolves 1
