PURPOSE Despite considerable potential for improving health care quality, adoption of new technologies, such as electronic medical records (EMRs), requires prudence, to ensure that such tools are designed, implemented, and used meaningfully to facilitate patient-centered communication and care processes, and better health outcomes. The association between patients' perceptions of health care provider use of EMRs and health care quality ratings was assessed. METHOD Data from two iterations of the Health Information National Trends Survey, fielded in 2011 and 2012, were pooled for these analyses. The data were collected via mailed questionnaire, using a nationally representative listing of home addresses as the sampling frame (n=7,390). All data were weighted to provide representative estimates of quality of care ratings and physician use of EMR, in the adult US population. Descriptive statistics, t-tests, and multivariable linear regression analyses were conducted. RESULTS EMR use was reported significantly more frequently by females, younger age groups, non-Hispanic whites, and those with higher education, higher incomes, health insurance, and a usual source of health care. Respondents who reported physician use of EMRs had significantly higher ratings of care quality (Beta=4.83, standard error [SE]=1.7, P<0.01), controlling for sociodemographic characteristics, usual source of health care, and health insurance status. CONCLUSION Nationally representative data suggest that patients' perceptions of EMR use are associated with their perceptions of the quality of the health care they receive.
