From the 2007 National Ambulatory Medical Care Survey, Electronic Health Records Survey:
Does your practice use electronic medical records?
The NAMCS Electronic Health Records Survey is a mail survey affiliated with the in-person NAMCS. Findings are based on a sample of non-federal employed office-based physicians who are primarily engaged in direct patient care. Physicians in the specialties of anesthesiology, pathology, and radiology are excluded from the survey.
Medical practices are considered to use electronic records if they indicate any use (all electronic or part electronic).
