NOTE: Data from 1994-1996 can be downloaded from the CDC/FTP server.

HSIC also has three tape cartridges which contain this data.

A single CD-ROM with 1994-96 data is available, but HSIC does not own it at this time.

For information about data collection, variables, and results go to these NCHS webpages:

• NSAS National Survey of Ambulatory Surgery, Public Use Data Files (from the Catalog of Electronic Data Products)
• National Hospital Discharge and Ambulatory Surgery Data
