About the National Data

Data

Data Source:  Medicare Current Beneficiary Survey (MCBS), CMS

Baseline: 59.7 percent of adults aged 65 years and over with diagnosed Alzheimer's disease and other dementias, or their caregiver, were aware of the diagnosis in 2013-15

Target: 65.1 percent

Numerator
Number of adults aged 65 years and over diagnosed with Alzheimer's disease or other type of dementia, or their caregiver, who are aware of the diagnosis.
Denominator
Number of adults aged 65 years and over diagnosed with Alzheimer's disease or other types of dementia, persons receiving treatment for Alzheimer's disease or other types of dementia (ICD-10 codes: DX F01.50, F01.51, F02.80, F02.81, F03.90, F03.91, F04, G13.8, F05, F06.1, F06.8, G30.0, G30.1, G30.8, G30.9, G31.1, G31.2, G31.01, G31.09, G94, R41.81, R54, Any DX on the claim).
Target-setting method
Minimal statistical significance
Target-setting method details
Minimal statistical significance, assuming the same standard error for the target as for the baseline.
Target-setting method justification
Trend data were evaluated for this objective, but it was not possible to project a target because the trend was moving away from the desired direction, and the slope of the trend line was not statistically different from zero. The standard error was used to calculate a target based on minimal statistical significance, assuming the same standard error for the target as for the baseline. This method was used because it was a statistically significant improvement from the baseline and the Healthy People 2030 Workgroup Subject Matter Experts viewed this as an ambitious yet achievable target.
