Associations Between Cognitive Impairment Severity and Barriers to Healthcare Engagement Among Older Adults.

To assess whether older adults with a cognitive impairment were more likely to report challenges interacting with medical providers, or to avoid needed medical care. Data for this exploratory, cross-sectional analysis were from older adults ( = 493) ages 60-82 participating in the "LitCog" cohort study. Multivariable generalized linear models compared cognitive impairment (none, mild, moderate, severe) with validated measures of healthcare engagement. A moderate cognitive impairment was associated with delays in medical care due to embarrassment (RR 5.34.95% CI 1.30-22.0) and discomfort asking the doctor questions (RR 4.07, 95% CI 1.00-16.5). Intermediate cognitive deficits such as with mild cognitive impairment (MCI) or mild dementias, may impact meaningful engagement with healthcare systems, potentially affecting timely detection and appropriate management of cognitive concerns and other chronic medical conditions. More research is needed to understand mechanisms underlying this relationship.
