The future of healthcare informatics: it is not what you think

Electronic health records (EHRs) offer many valuable benefits for patient safety, but it becomes apparent that the effective application of healthcare informatics creates problems and unintended consequences. One problem that seems particularly challenging is integration. Painfully missing are low-cost, easy to implement, plug-and-play, nonintrusive integration solutions-healthcare's "killer app." Why is this? We must stop confusing application integration with information integration. Our goal must be to communicate data (ie, integrate information), not to integrate application functionality via complex and expensive application program interfaces (APIs). Communicating data simply requires a loosely coupled flow of data, as occurs today via email. In contrast, integration is a chief information officer's nightmare. Integrating applications, when we just wanted a bit of information, is akin to killing a gnat with a brick.
