Lower cognitive function may hinder access to outpatient healthcare services among older adults. Further research with administrative data is recommended to confirm these findings on healthcare utilization.

Area of Science:

  • Gerontology
  • Cognitive Science
  • Health Services Research

Background:

  • Cognitive function variation in aging populations is poorly understood.
  • The relationship between cognitive impairment and healthcare utilization/costs requires further investigation.

Purpose of the Study:

  • To develop a cognitive function typology in a national sample of the oldest old.
  • To evaluate acute healthcare use based on cognitive function levels, controlling for confounders.
  • To include individuals unable to self-respond through proxy assessments.

Main Methods:

  • Analysis of the Asset and Health Dynamics Among the Oldest Old (AHEAD) survey baseline data.
  • Categorization into three cognitive function levels using direct and proxy measures (n=7,443).

  • A two-part model to predict healthcare service use and intensity.

    • Main Results:

    • Cognitive function groups (low, moderate, high: 16%, 64%, 20%) differed significantly across demographic and health measures.
    • Lower cognitive function was associated with reduced outpatient service use.
    • Cognitive function did not directly impact hospital use when controlling for other factors.

    Conclusions:

    • Reduced cognitive function may act as a barrier to accessing outpatient care.
    • Replication with administrative healthcare utilization and cost data is advised.
