We published the HL7 Survival Guide as a series of blog posts on the Caristix website. It’s now available as a single PDF download. Our goal was to clear up misconceptions about interfacing and HL7 — including the fact that some people think HL7 v2 and traditional interfacing are going away with Meaningful Use and CDA. Take a look and let me know what you think. I’m always open to feedback, which we’ll incorporate when we get started on the second edition.
