Preventive Care in Advanced Dementia: When Less Is More
89-year-old man with advanced Alzheimer disease lives in a nursing home. He has dysphagia and two aspiration pneumonia admissions in 6 months, BMI 19, and eGFR 25 mL/min/1.73 m². He had an MI 15 years ago. Medications: aspirin 81 mg daily, atorvastatin 80 mg daily, alendronate 70 mg weekly, vitamin D 800 IU daily, donepezil 10 mg daily. There is no advance directive. His daughter is health care proxy and wants “everything, including colonoscopy,” because he is “still eating.” He has had no cancer screening for 10 years. He is bed-to-chair, has a stage 2 sacral pressure injury, and cannot state his goals. He is not acutely ill. The nursing home pharmacist flags the medication list for review. The daughter asks whether stopping any medicine would be “giving up.”
1. Which preventive medications should be continued, stopped, or deprescribed, and why?

Frame this around goals. At 89 with advanced dementia, dysphagia, recurrent aspiration, and eGFR 25, he has a limited life expectancy and a high symptom burden; preventive drugs with delayed benefit are unlikely to help. Alendronate should stop: he cannot safely swallow it, he has limited mobility, and fracture prevention over years is not a realistic goal. Atorvastatin for secondary prevention is debatable; if his goals are comfort and he has no recent ACS or stent, deprescribe it, because the absolute benefit late in life is small and it adds pill burden. Aspirin for secondary prevention also needs review; if he has no recent stent and bleeding risk is high, stop it after discussing with the daughter. Vitamin D can continue; it is low-burden and may help bone health. Donepezil has questionable benefit in advanced dementia, can cause bradycardia and weight loss, and should be reconsidered.
2. How would you respond to the daughter's request for colonoscopy?
Read the worked answer
Acknowledge her love and fear: she does not want to feel she is giving up. Explain that colonoscopy is not a neutral test in an 89-year-old with dementia, dysphagia, and aspiration risk: bowel prep, sedation, dehydration, perforation, and delirium are real harms, while the chance of preventing a cancer death is very small given his life expectancy. Ask what her father would have wanted and what she understands his current quality of life to be. Offer a focus on comfort: aspiration precautions, pressure injury care, pain, constipation, and meaningful interaction. If she still wants screening, clarify that a less invasive test would not change management unless he would accept treatment. If conflict persists, involve palliative care or ethics.
3. What documentation and care planning steps are needed?
Read the worked answer
Assess and document decision-making capacity; if he lacks it, identify the daughter as surrogate and confirm the hierarchy under state law. Hold a goals-of-care conversation with the daughter and document the patient’s values, acceptable quality of life, and preferences for hospitalization, antibiotics, and artificial nutrition. Complete a POLST or equivalent if available, and update the advance directive. Do a deprescribing plan with clear stop dates and monitoring for withdrawal or symptom rebound. Involve palliative care, nursing, pharmacy, and speech-language pathology for dysphagia. Revisit the plan after any hospitalization, because goals often change. Record that stopping preventive medicines is an active comfort-focused decision, not abandonment.
