Health Care Access and Utilization: Follow Up Survey Details and Resources

Survey Design

The All of Us Research Program Health Care Access and Utilization survey asks about participants' access to and use of health care. The survey includes 58 items (47 main items and 11 related follow-ups) items from the The National Health Interview Survey (NHIS) and items developed specifically for use within the All of Us Research Program.

Scoring Considerations for the Health Care Access and Utilization Survey

The Health Care Access and Utilization survey is composed primarily of items from the National Health Interview Survey (NHIS) that are not meant to be scored. 

Sample Eligibility

The survey is considered a “follow-up” survey and is available to all All of Us participants after completion of the Basics, Overall Health, and Lifestyle surveys.

For more information about survey samples and releases, please see Introduction to All of Us Survey Collection and Data Transformation Methods.

Data Model & Privacy Protection Considerations

All survey codebook variables (e.g., source codes) are deposited into the OMOP Common Data Model’s observation table and stored as concepts in an AoU specific “PPI” vocabulary. This vocabulary is both browsable and downloadable via Athena, the online OMOP repository - for a listing of concepts specific to the Health Care Access and Utilization survey, please see this Athena entry. 

Select items from the Health Care Access and Utilization survey have been either suppressed or generalized within the Registered and Controlled Tiers. Please see below for these specifics, which are also captured in the All of Us survey codebook and How All of Us Protects Participant Privacy.
