Hospital Ambulatory Medical Care Survey (NHAMCS) Data
Highlights - Selected Tables, Charts, and Graphics Survey
Methodology Reason for Visit Classification, Drug Entry List, Generic Ingredient List: These classifications are updated on an annual basis and printed in the documentation for each survey year. In addition, text formats for reason for visit, drug entry, and generic ingredient codes are all available in downloadable SAS formats for data years 1993-2006 and SPSS syntax files for 2002-2006. The SAS and SPSS formats also include text labels for the following codes: diagnosis, cause of injury, procedures, and therapeutic class of drug.
List of survey items, 1973-2006 Publications using NAMCS/NHAMCS data NAMCS/NHAMCS Publications List - This contains a complete chronological listing of citations for all NCHS reports, journal articles, and other publications using NAMCS and NHAMCS data. It is meant to be a reference document and does not provide links to downloadable reports. Downloadable NCHS Reports - Selected NCHS reports are listed here, which can be viewed or downloaded. Public-Use
Data Files (micro-data) (1973-2006) However, data users should note
that, beginning with the 2002 public use files, two new masked design
variables were added to the file, for use with statistical software that
assumes a single stage of sampling. For the 2003 public use files
and beyond, the
decision was made to include only these two masked design variables
for variance estimation.
Therefore, data users who wish to combine years of data from 2003
and beyond with
years prior to 2002 will need to create these two variables for each file
prior to 2002. A technical paper, Using Ultimate Cluster Models with
NAMCS and NHAMCS Public Use Files, gives instructions.

NAMCS and NHAMCS data can also be downloaded
from the Inter-University Consortium for Political and Social Research
(ICPSR).
