HL7 Interfacing: The last mile is the longest.

Tim Gee mentions the Mirth Project as a cost effective solution for RHIOs (regional health information organizations). In particular, he notes that the WebReach appliance is "ready to go" hardware and software.

I've recently started looking at HL7 interface engines for providing our ICG electronic records to customer EMR systems. I've mainly been evaluating Mirth and NeoIntegrate from Neotool.

One of the Neotool bullet points about HL7 V2 states:

Not “Plug and Play” - it provides 80 percent of the interface and a framework to negotiate the remaining 20 percent on an interface-by-interface basis

Since HL7 V2 is the most widely adopted interface in the US, that last 20% can be a significant challenge. This is one of the primary purposes for HL7 integration tools like Mirth and NeoIntegrate -- to make it as easy as possible to complete that last mile.

If you look closely at the Mirth appliance literature you'll see this in the Support section:

For customers requiring assistance with channel development, WebReach consulting and engineering services are available, and any custom work performed by WebReach can be added to your annual support agreement.

They're providing a turn-key hardware and integration engine system, but you either have to create the custom interfaces yourself or hire them (or someone else) to do it for you.

<AnalogyAlert>
This means that you have bought the hammer and identified the nail(s) to pound in. All you need to do now is find and hire a carpenter to complete the job.
</AnalogyAlert>

This really shouldn't be that surprising though. Custom engineering and support is the business model for the WebReach Mirth project and I'm sure a large revenue generator for Neotool.

There is certainly great value in being able to purchase a preconfigured and supported HL7 interface appliance. Just be aware that it's not quite ready to go.

Update 17-Dec-07:

If anyone has experience using HL7 integration engines that they'd like to share, I'd love to here for you (preferably through the comments so they're shared, but private mail is also fine). In particular, I know there are a number of competing offerings to the ones mentioned in this post, and it would be good to know if they are worth evaluating. Thanks!

    Hi

    I agree with you. I was looking for a interface engine, found couple of but nobody says it can be used to build complete interface. Some vendors say a prototype can be built for testing ?

    Right you are Bob. Perhaps I should not have been so casual in describing anything about HL7 being “ready to go.”

  3. This explains well why doctors need to realize why an EMR or lab might charge you to build an interface for you. It’s not as plug n play as we’d all like it to be.
