Yesterday we tried to put EHRs into perspective. They're important, and we can't effectively move health care forward without them. But they're only one of many important health IT functions. EHRs and health IT alone won't fix health care. So developing a comprehensive but effective national health IT plan is a huge undertaking that requires broad, non-ideological thinking.

As we've learned so painfully elsewhere in the economy, the danger we face now in developing health care solutions is throwing good money after bad. We don't merely need a readjustment of how health IT dollars are spent. We need to reboot the entire conversation about how health IT relates to health, health care, and health care reform. To get there, we need to take a deep breath and start from well-established and agreed-upon principles.

Most of us want a health system that, whenever possible, bases care on knowledge of what does and doesn't work - i.e., evidence. We want care that is coordinated, not fragmented, across the continuum of settings, visits and events. And we want care that is personal, affordable and increasingly convenient.

Most of us also agree that, so far, we have not achieved these ideals. In fact, health care continues to become costlier, quality is spotty, and the gap between the health care we believe possible and the current system is widening.

We believe that most health care professionals are acutely aware that more health IT alone cannot resolve these problems. Despite billions of dollars in health IT investments by health care professionals and organizations, the gap persists and is widening. Many physician practices have expanded their health IT functions, moving beyond electronic billing systems - a necessary asset to be paid by Medicare - toward EMRs and from paper to software systems.  About a quarter of US physicians use EHRs from commercial vendors. Hospitals and health plans - larger, corporate organizations with more dedicated capital resources - have implemented health IT more quickly. Even so, the tools implemented have typically been focused on record-keeping and transactional processing, not decision-support. Health care clinical and administrative decisions have not yet become more rational, less tolerant of waste and duplication, or more congruent with evidence.

We don't need simply more health health IT; instead, we need an array of specific health IT functions and capabilities that can facilitate better care at lower cost, and the adherence to evidence-based rules.

What would those empowering health IT products look like, and what would they do?
