By sovita.chander@caristix.com | Published: May 9th, 2014

Tip 9 in the Interoperability Tip Series

In Tip 8, we explained what an HL7 interface specification should include. In this tip, learn how to develop an HL7 interface specification, which you’ll need for each interface you develop.

(A quick note about terms. There is no standard term for a spec. Some people call them a profile, conformance profile, schema. We use the term profile or HL7 profile in our software. We use the terms specification, conformance profile, and profile interchangeably in [...]

Tip 8 in the Interoperability Tip Series

Critical Elements in an HL7 Interface Specification

These are critical elements a developer needs to create a interface that works (almost) out of the box with minimal testing. The more accurate the HL7 interface specification, the faster it’ll be implemented – and the less costly the work will be.

1. Interface nameHow do you refer to your interface in your integration environment? Some organizations manage thousands of interfaces. If you’ve got 10 or 20 interfaces, no [...]

Gap Analysis and CCD Document Specification

By sovita.chander@caristix.com | Published: April 28th, 2014

Bridging the Gaps

In a previous post on CCD, C-CDA, and CDA, we compared HL7 v2 messaging to CCD development. This week’s article is about the biggest roadblock with CCD document specification: gap analysis.

What is Gap Analysis?

Simply put, gap analysis is about understanding the differences in the data between two systems. The output of a gap analysis process is a list of all the differences between two systems charted in a requirements document. With HL7 v2 messaging, many organizations create their [...]

Tip 7 in the Interoperability Tip Series

Communicating These Needs to Leadership

These are the most important assets you’ll need when you’re working on creating new interfaces or converting existing ones from one system to another. You’ll need to create them manually, or automate this work via interface lifecycle software.

Why These Assets?

Besides making sure that you have complete requirements so that you can accurately scope a project, you need to make sure you have all the parts and piece lined up and [...]

HL7v2 to CCD

By sovita.chander@caristix.com | Published: April 22nd, 2014

Confused? Start with What You Know

Over the past few months, we’ve heard a lot from our hospital-based customers about CCD and C-CDA readiness. There’s more urgency with Meaningful Use Stage 2 deadlines, even with the extension.

But the funny thing is: hardly anyone ever says, darn, but this is confusing.

Sometimes people express their frustration. “What the heck are those regulators doing? Why are they pushing more stuff at us, when we’re barely able to keep up as it is?”

Others bury their [...]

What is One-Hour Interoperability?

By sovita.chander@caristix.com | Published: April 15th, 2014

The Status Quo

This is the world interface analysts, developers, and quality testers work in:

2 weeks to get a list of code values for a single field
1 week to get a list of custom field formats like lab order codes
20 hours to code a schema in an engine from a spec in Excel
9 days on gap analysis
30 days to test a 10-minute code change
8 versions of a spec before it’s baked enough for development

Productivity with Caristix

With our software, especially with the [...]
