Ambulatory Health Care Data

What's New

 

Did You Know?

  • NAMCS data can be used to make physician estimates as well as visit estimates.
  • As part of the survey induction process, physicians are interviewed about themselves and their practices, using the Physician Induction Interview Form. NAMCS public use files from 2005 forward contain a physician-level weight that can be used to make estimates of office-based physicians who saw patients during their reporting week, representing the majority of NAMCS participants. The public use files contain a variety of physician-level variables, and additional items [PDF - 50 KB] are available through the NCHS Research Data Center. The RDC files also contain records for NAMCS physicians who are not included on the public use files for various reasons (did not see patients during reporting week, did not submit visit forms). Including these physicians in one’s analysis along with those who saw patients can provide national estimates of all office-based physicians.
  • A recent example of physician-level NAMCS data appeared in the QuickStats section of CDC’s Morbidity and Mortality Weekly Report (MMWR). It shows acceptance by physicians of various forms of payment from new patients in 1999-00 and 2008-09.
  • A new NAMCS Public Use Physician Trend File covering survey years 2005-2010 is now available; see under Data Products for more information.

NAMCS Continuing Medical Education Course

The NAMCS Continuing Medical Education course is now available! The course entitled, “National Ambulatory Medical Care Survey Methods: What Clinicians Need to Know”, has been approved to offer 1.0 continuing medical education (CME) credit, 1.0 continuing nursing education (CNE) credit, and 0.1 continuing education (CEU) credit for physicians, nurses, and other health professionals who register for and complete the online module.

Ambulatory Care Drug Database

It was recently discovered that a March 2012 CDC system update may have caused an error in the Ambulatory Care Drug Database.  As a result, some drugs were displaying in search results without a corresponding number of “2009 Mentions”.  The problem appears to have been identified and resolved.  We will continue to monitor the database periodically to check for any further anomalies.  Please keep in mind that the main function of the database is to help researchers identify codes and characteristics of drugs that have been reported in NAMCS and NHAMCS in order to facilitate research efforts.
