Which physicians and practices are using electronic medical records?

Greater use of electronic medical records (EMRs) has the potential to improve the quality of medical care and has become a goal of the U.S. administration. According to the National Ambulatory Medical Care Survey, only an average of 17.6 percent of physicians reported use of EMRs in their office-based practices. The adoption rate did not increase from 2001 through 2003. Practices with more physicians and those owned by health maintenance organizations (HMOs) were significantly more likely to use this technology, but use varied little by the characteristics of individual physicians, the practice's scope of services, or the practice's sources of revenue.
