WASHINGTON – Hospitals' use of electronic health records has had just a limited effect on improving the quality of medical care nationwide, according to a study by the nonprofit RAND Corporation.
The study, published online by the American Journal of Managed Care, is part of a growing body of evidence suggesting that new methods should be developed to measure the impact of health information technology on the quality of hospital care.

However, quality scores improved no faster at hospitals that had newly adopted a basic electronic health record than in hospitals that did not adopt the technology. In addition, at hospitals with newly adopted advanced electronic health records, quality scores for heart attack and heart failure improved significantly less than at hospitals that did not have electronic health records. EHRs had no impact on the quality of care for patients treated for pneumonia.

"The lurking question has been whether we are examining the right measures to truly test the effectiveness of health information technology," said Spencer S. Jones, the study's lead author and an information scientist at RAND. "Our existing tools are probably not the ones we need going forward to adequately track the nation's investment in health information technology."

Support for the study was provided by RAND COMPARE (Comprehensive Assessment of Reform Efforts). RAND developed COMPARE to provide objective facts and analysis to inform the dialogue about health policy options. COMPARE is funded by a consortium of individuals, corporations, corporate foundations, private foundations and health system stakeholders.
Other authors of the study are John L. Adams, Eric C. Schneider, Jeanne S. Ringel and Elizabeth A. McGlynn.

The private health system is funded by a number of private health insurance organisations. The largest of these is Medibank Private, which is government owned, but operates as a government business enterprise under the same regulatory regime as all other registered private health funds. Thanks a lot.
It is a record in digital format that is theoretically capable of being shared across different health care settings. In some cases this sharing can occur by way of network connected enterprise wide information systems and other information networks or exchanges. Thanks.
Relaxation techniques are physical methods used to relieve stress. Psychological methods include cognitive therapy, meditation, and positive thinking, which work by reducing response to stress. Thanks.
