Interoperability

Anecdote-driven systems engineering and complaint-based interoperability design will not solve health IT woes

As I’ve been preparing to chair the HealthIMPACT conference in Houston next Thursday I’ve been having some terrific conversations with big companies like Cisco, some of our publishing partners, and smaller vendors entering the health IT space for the first time. One great question I was asked during a discussing yesterday by a tech publisher was “so what’s it going to take to achieve real interoperability in healthcare and how long will it take?

I’ve often said that Meaningful Use and the HITECH Act created false demand for EHRs and has (perhaps irrevocably) harmed innovation in the EHR space by standardizing features and function rather than outcomes and expectations. It’s a false demand because it concentrated too much on prescriptive, sometimes useless, and in many cases productivity-killing, functionality instead of focusing on what’s really needed — data interoperability and fostering innovation. John Halamka wrote something similar recently in his Advice to the new ONC chief (highlights in red below are mine, not John’s):

Most health IT interoperability and connectivity discussions these days center around HL7, CCD, and other structured data interchange. However, the vast majority of data (in terms of size) is shared as images and documents. The DICOM and PACS standards are very successful but given the number of questions I get about them from readers it seems there’s still a lot of guidance and support needed. To help answer some of the most common technical questions, I reached out to a fellow health IT expert, Herman Oosterwijk from OTech.
