National Hospital Care Survey

Annual Hospital Interview

The Annual Hospital Interview (AHI) is a yearly supplemental component of the National Hospital Care Survey (NHCS). All sampled hospitals are asked to complete the AHI to create national estimates on hospital care and utilization.

The AHI asks hospitals to provide summary information on emergency department, outpatient department, and inpatient department visits for the calendar year. This information will be used for statistical purposes and for further insight on sampled hospitals.

AHI Portal

The AHI is accessible on the AHI Portal. Hospitals invited to complete the AHI will receive an invitation email with their four-digit NHCS-sampled hospital identifier and instructions to access the AHI Portal. The invitation email will be sent by ahi-support@cdc.gov. For Frequently Asked Questions (FAQs), please view the FAQs pdf icon[PDF – 275 KB].
