National Ambulatory Medical Care Survey - Electronic Health Records Survey
The National Ambulatory Medical Care Survey (NAMCS) focuses on visits made to non-federally employed office-based physicians who are primarily engaged in direct patient care. Beginning in 2006, the survey also includes an annual sample of visits to community health centers (CHCs). NAMCS provides information on patient, provider, and visit characteristics. The annual NAMCS physician sample is composed of doctors of medicine (MDs) and doctors of osteopathy (DOs) representing an array of medical specialties. Physicians are randomly selected based on information obtained from the masterfiles of the American Medical Association (AMA) and the American Osteopathic Association (AOA). The CHC sample is maintained by the Health Resources and Services Administration (HRSA). In addition to the standard in-person NAMCS, a mail survey examining adoption of electronic health records (EMRs)/electronic medical records (EHRs) is mailed to physicians who are otherwise eligible for NAMCS, but have not been selected in the regular NAMCS sample. The mail survey has been fielded continuously since 2008.
