Why Do HL7 Interfaces Take So Long to Write?

HL7 Interfacing Advice from the Indiana Health Information Exchange

The largest health information exchange (HIE) in the US is located in Indiana. It connects 80 hospitals, and serves 10 million patients as well as 19,000 physicians. IHIE members participated in a recent meeting of the Central Indiana Beacon Community and posted their slide decks here. The presentation that resonated for us was Mapping Interfaces by Dr. Mike Barnes, Dan Vreeman, and Amanda Smiley (PDF).

Their killer quote: “Interface programmers are the only [...]

Protecting Patient Data in HL7 Logs

By sovita.chander@caristix.com | Published: January 28th, 2011

Information Week ran an article this week on protecting patient data. The article wasn’t on one of the usual suspects — a HIPAA violation or a breach in a production system. Instead, this was notable because we’re finally seeing one of the hidden dangers in healthcare IT coming to light: unsecured patient data sitting in development and test systems. Our industry needs to start addressing this issue.

Information Week cited a survey where 51% of organizations don’t protect patient data used [...]

Guest Post on Healthcare IT Guy

By sovita.chander@caristix.com | Published: January 12th, 2011

Jean-Luc Morin, VP R&D at Caristix, has a guest post on Shahid Shah’s blog, Healthcare IT Guy. Shahid’s top-ranked blog covers healthcare IT, EMR, EHR, PHR, medical content, and document management.

Jean-Luc’s article covers 6 questions hospital CIOs and IT directors should be asking vendors about interface documentation.

Here’s an excerpt:

At first glance, documentation doesn’t seem like a CIO-level concern. In a typical implementation cycle, the team gets a few specs from a vendor. Someone signs off on an interface configuration document. [...]

Will HL7 V3 Adoption Take Off in 2011? 5 Points and 1 Caveat

By jeanluc.morin@caristix.com | Published: January 4th, 2011

A few weeks ago, I was working on an HL7 v3 project with an outside partner and the discussion turned to market adoption. We came to the conclusion that it’s not exactly taking off — at least, not as quickly as you might expect. Apart from meaningful-use initiatives around CDA in the US and the big push by Canada Health Infoway, I don’t really see much traction in North America. I’m going to come right out and say this: from [...]

Definitions

We’re continuing with our series of posts on patient data de-identification. This week, we’re reviewing a set of definitions of common terms.

De-identifying Patient Data, Part 1

By jeanluc.morin@caristix.com | Published: November 30th, 2010

In healthcare IT, no matter where you work, you’re faced with protecting patient data. Many countries have regulatory frameworks to address patient privacy and the use of health information. In the US, HIPAA regulates the use of PHI (protected health information). In Canada, the law is called PIPEDA (Personal Information Protection and Electronic Documents Act). PIPEDA regulates the use of consumer data in a number of industries, not just healthcare. Plus a few Canadian provinces have their own privacy legislation [...]

What if HL7 interface specifications were easy to document?

By sovita.chander@caristix.com | Published: November 23rd, 2010

Some organizations call them HL7 conformance profiles, others call them HL7 interface specifications. They’re all talking about a description of the data format used for exchange between systems within a care facility.

The terminology might not be consistent, but the challenge is: documentation. How do you document conformance profiles so that the description is up-to-date and trustable?

3 HL7 Documentation Issues
1. Creation is Time Consuming

Documenting an HL7 specification requires a fair amount of effort. Applications exchanging data through the HL7 standard usually [...]

By stephane.vigot@caristix.com | Published: November 19th, 2010

I was in Philadelphia this week for the 2nd Annual Canada-US eHealth Summit (PDF). Now, this wasn’t a big conference like HIMSS.

Plus, we got to hear from a handful of respected HIT leaders, including John Glaser, CEO of Siemens HIT, and David Levine, head of a major Canadian regional health agency.

Here are 15 highlights from the presentations.
