About the National Data

Data

Data Source:  National Health Interview Survey (NHIS), CDC/NCHS

Baseline: 13.2 per 1,000 adults aged 45 years and over had visual impairment due to glaucoma in 2017

Target: 10.6 per 1,000

Numerator
Number of adults aged 45 years and over with glaucoma, who have lost vision because of glaucoma.
Denominator
Number of adults aged 45 years and over.
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 projections were not statistically significant improvements from the baseline. 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.

Methodology

Questions used to obtain the national baseline data

(For additional information, please visit the data source page linked above.)

From the 2017 National Health Interview Survey Vision Supplement:

Numerator and Denominator:
Have you ever been told by a doctor or other health professional that you had glaucoma?
  1. Yes
  2. No
  3. Refused
  4. Don't know

If answered "yes" (1) then asked:

Have you lost any vision because of glaucoma?
  1. Yes
  2. No
  3. Refused
  4. Don't know

Methodology notes

Persons who responded "yes" to the two Numerator questions met the (self-reporting) criteria for this objective.
