Clinical Report: Patterns of Medication Initiation and Continuation Impacting Cognitive Function in Elderly Patients
Overview
This study examines the initiation and continuation of medications affecting cognition, specifically antipsychotics, in older adults, revealing a significant proportion of prescriptions initiated from acute or postacute settings. Notably, a high percentage of patients continued these medications one year later, raising concerns about their cognitive impact and associated risks such as delirium and falls.
Background
The use of medications that adversely affect cognition, such as antipsychotics, is prevalent among older adults, despite associated risks like delirium and falls. Understanding the contexts in which these medications are prescribed is crucial for improving patient safety and cognitive outcomes. This study provides insights into the initiation patterns and continuation rates of such medications among elderly patients, emphasizing the need for careful prescribing practices.

Key Findings
22.0% of dementia patients' visits were to acute/postacute settings, but 43.3% initiated antipsychotics from these settings.
67.1% of dementia patients continued antipsychotics one year after initiation.
14.2% of patients with no cognitive impairment initiated medications from acute/postacute settings.
38.2% of patients with no cognitive impairment continued medications affecting cognition after one year.
Patients with CIND had a higher initiation rate from acute settings compared to those without cognitive impairment.
Clinical Implications
Healthcare providers should be vigilant about the initiation of cognitive-affecting medications in acute settings and consider the long-term implications of continued use. Regular medication reviews and deprescribing strategies may be necessary to mitigate cognitive risks in older adults.
Conclusion
The study highlights the concerning trend of initiating cognitive-affecting medications in acute settings and the high rates of continuation, underscoring the need for careful prescribing practices in elderly patients.
In a target-trial emulation of more than 600,000 veterans, GLP-1 RA initiators saw fewer new substance use disorders—and patients with existing SUDs had fewer overdoses, hospitalizations, and deaths.
This week's research makes one thing clear: who someone is before they get sick — their relationships, their partner's health, the back of their eye — is doing a lot of work medicine is only beginning to account for.
