A Hip Fracture, a Full Medicine Cabinet, and a Daughter Who Wants Her Mother Sedated
Mrs. D is an 84-year-old widow with mild dementia (baseline Mini-Mental State Examination 24) who lives with her daughter. She fell and sustained a right intertrochanteric femur fracture and underwent hemiarthroplasty two days ago. Her medications include donepezil 10 mg, memantine 10 mg twice daily, oxybutynin 5 mg twice daily, diphenhydramine 25 mg nightly for sleep, morphine 2 mg intravenously every 4 hours as needed, and scheduled polyethylene glycol. Tonight she is awake, calling for her dead husband, pulling at her intravenous line and urinary catheter, and trying to climb out of bed; at other times she is quiet and staring. Staff ask for 'something to calm her down.' Her daughter says, 'My mother would never act like this - please just sedate her.' There is no documented goals-of-care discussion and no appointed health care agent.
1. What is your differential for her behavior, and what is the first-line evaluation and management?
Read the worked answer
This is delirium superimposed on dementia until proven otherwise - not 'sundowning' and not just grief.
Look for the reversible drivers before reaching for a sedative
- Pain: undertreated hip pain is the most common cause; assess with an observational tool and give scheduled acetaminophen, then opioid as needed.
- Urinary retention from the oxybutynin plus immobility, and fecal impaction despite polyethylene glycol.
- Infection: pneumonia, urinary tract infection, wound infection; check oxygen saturation, temperature, urinalysis, chest radiograph.
- Metabolic and cardiac: electrolytes, glucose, renal function, occult myocardial infarction, pulmonary embolism, hypoxia.
- Drugs: diphenhydramine and oxybutynin are potent anticholinergics and should stop; morphine metabolites accumulate in older adults and in kidney injury; review for new additions.
- Surgical complication: dislocation, hematoma, compartment syndrome.
Nonpharmacologic measures are treatment, not comfort measures
- Glasses and hearing aids in place; family presence; consistent staff; daylight exposure; a quiet, lit room at night.
- Remove the catheter and intravenous line as soon as possible; they are restraints in disguise.
- Mobilize with assistance, avoid bed and chair alarms, avoid physical restraints.
- A sleep protocol that does not rely on diphenhydramine.
Reassess within hours, not days; a fluctuating course with inattention is the diagnostic handle.
2. If nonpharmacologic measures fail and she remains distressed, what would you prescribe, what would you avoid, and what would you tell her daughter?

Prescribe
- Haloperidol 0.25–0.5 mg by mouth or intravenously every 6–12 hours as needed, or quetiapine 12.5–25 mg at night if she is very drowsy-prone. Start at the lowest dose, use it for a defined period, and reassess daily with a plan to taper once the delirium resolves.
Avoid
- Benzodiazepines - they worsen and prolong delirium, cause paradoxical agitation, and increase falls. Reserve them for alcohol or benzodiazepine withdrawal, or catatonia.
- Diphenhydramine, hydroxyzine, and oxybutynin - anticholinergic burden.
- Quetiapine or haloperidol in suspected Lewy body disease can cause severe rigidity; if parkinsonism or visual hallucinations predate the admission, use quetiapine cautiously or consult psychiatry.
- Physical restraints - they increase injury and delirium.
What to tell her daughter
- Name the diagnosis: 'Your mother has delirium - a sudden brain failure from pain, surgery, and medications. It is common, it is usually temporary, and it is not the end of her personality.'
- Be honest about the medications: antipsychotics are not approved for this use and carry a boxed warning about increased mortality in older adults with dementia. We use the smallest dose for the shortest time because the distress is worse than the small risk, and we stop as soon as we can.
- Do not promise sedation as the goal; promise comfort and safety, and set a 24-hour reassessment.
3. How does her dementia trajectory change the goals-of-care conversation, and what would you recommend regarding hospice or palliative care involvement?
Read the worked answer
Use the event as a trigger, not a crisis. Hip fracture in advanced dementia carries roughly 30–40% one-year mortality and often marks a permanent functional decline. That is a legitimate opening: 'She was managing at home before this. If she cannot walk again, what would she want?'
Concrete steps
- Ask about her prior statements, and identify the daughter's legal standing as surrogate; if not appointed, discuss a health care proxy or guardianship under state law.
- Clarify what matters: returning home, recognizing family, avoiding repeated hospitalizations, avoiding a feeding tube.
- Name the trajectory: dementia is a terminal illness. Incontinence of bladder and bowel, inability to walk, and minimal speech (Functional Assessment Staging stage 7) with a complication such as hip fracture or pneumonia would support hospice eligibility; she may not meet criteria today.
- Bring in palliative care now for symptom management and family support, not only at discharge planning.
- Set a time-limited rehabilitation trial: 'Two weeks of therapy; if she is not standing with assistance, we revisit the goal.'
- Attend to the daughter's grief - she is already mourning the mother who would 'never act like this,' and that grief, not ignorance, is driving the request for sedation.
