NAMCS and NHAMCS Datasets and Documentation

Visit the National Ambulatory Medical Care Survey website at https://www.cdc.gov/nchs/namcs/ and the National Hospital Ambulatory Medical Care Survey at https://www.cdc.gov/nchs/nhamcs/ for more information about these surveys.

A NAMCS Public Use Physician Trend File is also available.  This file includes all previously released physician data from the 2005 through 2010 NAMCS Public Use Files; no visit data are included.  A single record is included for each physician in every survey year; each record contains information collected during the Physician Induction Interview along with a weighting variable which enables researchers to make national estimates. File documentation is also available for downloading, along with SAS files for reading and formatting the data.
