[영문]Building privacy and security protections into health information technology systems will bolster trust in such systems and promote their adoption. The privacy issue, too long seen as a barrier to electronic health information exchange, can be resolved through a comprehensive framework that implements core privacy principles, adopts trusted network design characteristics, and establishes oversight and accountability mechanisms. The public policy challenges of implementing this framework in a complex and evolving environment will require improvements to existing law, new rules for entities outside the traditional health care sector, a more nuanced approach to the role of consent, and stronger enforcement mechanisms.
