Medication Management Difficulty, Medication Nonadherence, and Risk of Hospitalization Among Cognitively Impaired...

Area of Science:

• Gerontology
• Neuroscience
• Public Health

Background:

• Effective disease management in older adults is crucial for preventing adverse outcomes.
• Medication adherence is a key factor, especially for individuals with cognitive impairment.
• Cognitive decline significantly impacts an older adult's ability to manage medications.

Purpose of the Study:

• To investigate the relationship between cognitive impairment and medication management.
• To assess the impact of cognitive function on medication adherence and hospitalization risk.
• To identify specific challenges in medication use across different cognitive function levels in older adults.

Main Methods:

• Analysis of data from 28,558 community-dwelling older adults.
• Categorization of participants based on cognitive function: dementia, cognitive impairment without dementia, and intact cognition.
• Statistical analysis to determine associations between cognitive status, medication management difficulties, nonadherence, and hospitalization.

Main Results:

• Individuals with dementia reported the highest medication management difficulties (13.12%), followed by cognitive impairment without dementia (5.80%), and intact cognition (1.96%).
• Medication management difficulty was significantly associated with increased hospitalization risk only in individuals with dementia (OR = 1.71).
• Cost-related nonadherence was linked to hospitalization risk exclusively in older adults with intact cognition (OR = 1.25).

Conclusions:

• Dementia is strongly associated with challenges in medication management, leading to a higher risk of hospitalization.
• Cognitive impairment necessitates tailored support systems for medication adherence in older populations.
• Understanding cognitive-specific medication management issues is vital for reducing adverse health outcomes and hospitalizations in older adults.
