Chronic Disease Indicators

Chronic Disease Indicators logo

The chronic disease indicators (CDI) are a set of surveillance indicators developed by consensus among CDC, the Council of State and Territorial Epidemiologists (CSTE), and the National Association of Chronic Disease Directors (NACDD). CDI enables public health professionals and policymakers to retrieve uniformly defined state and selected metropolitan-level data for chronic diseases and risk factors that have a substantial impact on public health. These indicators are essential for surveillance, prioritization, and evaluation of public health interventions. More

Notice to users:

The 2020 release includes the latest available CDI estimates across all topic areas. Due to changes in data collection (e.g., survey question deletions or modifications, or data abstraction changes), a few indicators were not updated with new estimates.

Indicators that have no updated estimates due to the absence of the “activity limitation” survey question in the BRFSS 2017 questionnaire include:

  • Activity limitation due to arthritis among adults aged ≥ 18 years who have doctor-diagnosed arthritis.
  • Prevalence of activity limitation among adults ≥ 18 with diagnosed chronic obstructive pulmonary disease.
  • Prevalence of activity limitation among adults ≥ 45 years with diagnosed chronic obstructive pulmonary disease.

New estimates are also unavailable for the indicator “Hospitalization for heart failure among Medicare-eligible persons aged ≥ 65 years”. Changes made to ICD-10 codes in 2017 for heart disease resulted in comparability concerns with previous years estimates.

In addition, the following new estimate should be reviewed with caution when compared to previous released estimates:

  • Cholesterol screening among adults aged ≥ 18 years. The survey question wording changed in 2017, resulting in higher estimates compared to previous years. The 2017 estimates may not be comparable to earlier years’ estimates and should be reviewed with caution.
  • With the National Survey of Children’s Health (NSCH) survey redesign in 2016, administration and question changes occurred beginning with the 2016 survey year. As a result, data on dental visits among children and adolescents aged 1–17 years and on preventive dental visits among children and adolescents aged 1–17 obtained from NSCH 2016 and onward are not comparable to data from prior years.

A footnote was mistakenly added to the 2013 US estimate indicator for healthy weight among high school students. Contrary to what is stated in the footnote, the 2013 US estimate is not a median of state estimates but is instead the estimated prevalence for the US. The footnote will be removed in the next CDI release.
