Clinical Table Search Service is a web service which software programs can use for querying clinical data tables. The API for each table is designed to work with our form field autocompletion package, but can be used by other programs as well. The tables may also be accessed through FHIR APIs. Check out the overview page and FAQ page for more details (including terms of use), and please contact us if you have further questions or if there are other clinical data tables you would like to see here. There is also an annoucements list for staying informed about changes.

Connectable Clinical Tables

What follows is a list of currently available tables with links to instructions for the APIs for programmatic access, and an example autocompleter for each table which uses that table's API.

Some of the data sets that we serve are stable (e.g., ICD-9-CM), while others are updated more frequently (e.g., ClinVar). We strive to keep our data up-to-date with respect to the data sources; in most cases it should be less than a month behind. Please refer to the "Details" column below for more information on a specific API's data version or date.
