Interoperable electronic prescribing in the United States: a progress report.

Although the vast majority of U.S. physicians still handwrite prescriptions, adoption of electronic prescribing is slowly growing. Major barriers to adoption remain, including the inability to electronically submit prescriptions for controlled substances and confusion about standards for data exchange. Federal and state governments and private insurers are using payment and policy incentives to boost e-prescribing because they still believe in its promise for improving the quality and efficiency of health care. However, additional efforts and further investments are needed to reap the benefits of e-prescribing on a national scale.
