Abstract
The objectives and assumptions of health care reform have changed repeatedly during the past century and may now be entering a new historical phase as a result of the "new economy" rooted in information technology. In a high-growth context, proponents of reform may no longer feel obliged to bundle expanded coverage with tighter cost containment. At the same time, the new digital environment may facilitate innovations intended to inform and expand consumer choice and to improve quality. The new environment elevates "transparency" to a guiding principle. Health informatics has long been peripheral to reform and must now become more central.
