Medication Management in a Cognitively Impaired Older Adult
Mrs. L, an 82-year-old widow, lives alone in a second-floor apartment. She has mild cognitive impairment (MCI) and takes seven medications, including warfarin, metoprolol, and insulin. Her daughter visits weekly and fills a pill organizer. Last month, Mrs. L missed two warfarin doses and took an extra metoprolol on one day. She has had two falls in the past six months, both without injury. Her MMSE score is 24/30. She insists on staying home and refuses a move to assisted living. The case manager must balance safety with autonomy.
1. What are the key risk factors for medication mismanagement in this case, and how should the case manager prioritize them?
Read the worked answer
Key risk factors include: cognitive impairment (MCI), complex medication regimen (7 meds, including high-risk drugs like warfarin and insulin), living alone, recent medication errors, and history of falls. Prioritization should focus on the highest-risk medications: warfarin (bleeding risk) and insulin (hypoglycemia). The case manager should first assess Mrs. L's actual medication management ability (e.g., using a pill count, observing her fill the organizer), then consider simplifying the regimen with her prescriber (e.g., once-daily formulations, eliminating non-essential meds). A medication dispenser with reminders could be helpful, but must be evaluated for usability. Fall risk should be addressed through home safety evaluation and review of medications that contribute to falls (e.g., metoprolol, hypoglycemia). The case manager must respect autonomy while mitigating risk through education and support.
2. Mrs. L refuses any in-home help. How can the case manager address safety while honoring her autonomy?

The case manager should use a harm-reduction approach: acknowledge Mrs. L's right to decide, explore her reasons for refusal (e.g., privacy, cost, distrust), and negotiate limited, acceptable interventions. For example, propose a daily check-in call or a medical alert device. Involve her daughter with permission to provide oversight. Educate on the signs of bleeding and hypoglycemia. Schedule a follow-up to reassess. If risk escalates, consider a multidisciplinary team meeting including her physician and possibly adult protective services if self-neglect is suspected, but only as a last resort. Document the discussion and Mrs. L's choices.
