About the National Data

Data

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

Baseline: 58.8 percent of adults aged 18 years and over had a dilated eye examination within the past 2 years, as reported in 2017

Target: 61.1 percent

Numerator
Number of adults aged 18 years and over who report they had a dilated eye exam within the past 2 years.
Denominator
Number of adults aged 18 years and over.
Target-setting method

Projection

Target-setting method details
Linear trend fitted using weighted least squares and a projection at the 33 percent prediction interval.

Target-setting method justification
Trend data were evaluated for this objective. Using historical data points, a trend line was fitted using weighted least squares, and the trend was projected into the next decade. This method was used because three or more comparable data points were available, the projected value was within the range of possible values, and a projection at the 33 percent prediction interval was selected because a modest increase was projected, with data from 2016-17 showing slight increases in the percentage of adults getting comprehensive eye exams. The National Eye Health Education Program emphasizes this objective as a top priority, making this target ambitious yet achievable.

Methodology

Methodology notes

Among adults, the appropriate time interval for getting a dilated eye exam is generally considered to be within the past 2 years. Adults who respond "less than 1 month," "1 to 12 months," or "13 to 24 months" to the above question are considered to be getting a dilated eye exam within the appropriate time interval. Among persons with diabetes, the appropriate time interval is 1 year. Adults with diabetes who respond "less than 1 month" or "1-12 months" to the question are getting a dilated eye exam at the appropriate interval.

History

Comparable HP2020 objective
Retained, which includes core objectives that are continuing from Healthy People 2020 with no change in measurement.

1. Because Healthy People 2030 objectives have a desired direction (e.g., increase or decrease), the confidence level of a one-sided prediction interval can be used as an indication of how likely a target will be to achieve based on the historical data and fitted trend.
