Public-Use Data Files (Micro-data)

 

To NSAS 2006 Data Users:

The revised 2006 National Survey of Ambulatory Surgery (NSAS) public use data set is now available for downloading from our website. The revised public use file documentation is also available. We advise anyone who has used the earlier NSAS data set (released in October 2008) to re-run all analyses using the revised data set before reporting or publishing any 2006 NSAS data. The National Health Statistics Report Number 11, entitled "Ambulatory Surgery in the United States, 2006," [PDF - 468 KB]) has been revised and is now available. The reasons for the revision of the NSAS data set, which affected some of the procedure estimates, are discussed at the beginning of the public use file documentation and in the report. The report also explains that some other estimates of standard errors were printed incorrectly in the original report and these have been corrected. Estimates from the original report should not be used.
