FIGURE 2: Overlap of Claims-Based Definitions with EHR-Adjudicated Dementia, Overall and by Age.

FIGURE 2:

Percent of subjects with clinician-adjudicated dementia, among those meeting criteria for the base and refined claims-based definitions of dementia, overall and by age group.

Base clams-based definition: Indicator variable incorporating all ICD-10 diagnostic codes corresponding to the ICD-9 codes included in a previously validated claims-based dementia, identified using Centers for Medicare & Medicaid Services General Equivalence Mapping.

Refined claims-based definition: Indicator variable incorporating a modified set of ICD-10 diagnostic codes, in which we removed codes inconsistent with current diagnostic criteria for dementia.

Analytic sample: Comprised of subjects whose electronic health records were fully evaluated by clinician reviewers. Only the overall sample size is shown.

Reconstructed sample: Target overall sample, reconstructed from the analytic sample using inverse probability weighting. Only the overall sample size is show.
