Use of electronic medical records differs by specialty and office settings

OBJECTIVE: To assess differences in the use of electronic medical records (EMRs) among medical specialties and practice settings. METHODS: A cross-sectional retrospective study using nationally representative data from the National Ambulatory Medical Care Survey for the period 2003-2010 was performed. Bivariate and multivariate analyzes compared EMR use among physicians of 14 specialties and assessed variation by practice setting. Differences in EMR use by geographic region, patient characteristics, and physician office settings were also assessed. RESULTS: Bivariate and multivariate analysis demonstrated increased EMR use from 2003 to 2010, with 16% reporting at least partial use in 2003, rising to 52% in 2010 (p0.05). CONCLUSIONS: Uptake of EMR is increasing, although it is significantly slower in dermatology, ophthalmology, and psychiatry. Solo practitioners and owners of a practice have low frequencies of EMR use compared with non-solo practitioners and those who do not own their practice. Despite incentives for EMR adoption, physicians should carefully weigh which, if any, EMR to adopt in their practices.
