Survey Results and Products

Web Tables

The annual NAMCS and NHAMCS-ED and NHAMCS-OPD summaries that have been published in the National Health Statistics Report series since 2006 and, prior to that, in the Advance Data from Vital and Health Statistics series, have been discontinued. The last year for the annual summary publications was 2007. Highlights from each new year of NAMCS and NHAMCS data are now being featured in the shorter Data Brief series. However, the standard tables from the traditional summaries will continue to be produced in PDF format on the web. These are referred to as Summary Tables in the links below. Other tables are also available, some combining data across surveys or across years. Also shown are data from the National Electronic Health Records Survey (NEHRS), which started as a NAMCS supplement.

Publications using NAMCS/NHAMCS data


The Ambulatory and Hospital Care Statistics Branch compiles a series of Factsheets for each physician specialty group sampled in NAMCS. These sheets present data on ambulatory medical care visits by specialty and are given to sampled providers to demonstrate the types of data the survey collects. Factsheets are also compiled for hospital emergency and outpatient departments and given to NHAMCS participants.
