"Meaningful Use" of ambulatory EMR: Does it improve the quality and efficiency of health care?

The US government has initiated incentive programs to encourage the adoption of Electronic Medical Records (EMR). To qualify for the incentive payment, healthcare providers need to demonstrate "meaningful use" of EMR systems, which requires the use of certified EMRs and the implementation of a set of standard functionalities. In this paper, we examine how the meaningful use of EMRs would affect health care outcomes in outpatient settings. Our results show that the use of core functionalities required by "meaningful use" criteria and the use of certified EMRs have a positive impact on the quality and efficiency of health care. In addition, we find the relationship between the meaningful use and quality of care is moderated by the length of use. The implications of this study are also discussed.
