Avoiding the #1 Interface Validation Mistake

By sovita.chander@caristix.com | Published: October 19th, 2010

When provider organizations are on a tight deadline to implement or upgrade an EHR, EMR, HIS or other clinical system, setting up a test or staging system can seem like just another procedural hurdle. So it couldn’t hurt to just do the final testing in the live, production system, right?

Wrong.

Why It’s Tempting

It might seem quicker to simply tag test data as “Test Patient1″ in “Bed #1-T” and get it into the production EMR or HIS. You skip duplicate server (or [...]

Customer Success: Cardinal Health Canada

By sovita.chander@caristix.com | Published: October 12th, 2010

Here’s what Barry Holleman, Vice President, Clinical Technologies, at Cardinal Health Canada had to say recently about Caristix:

“Cardinal Health Canada was seeking ways to cut HL7 interface validation time on our product deployments, without sacrificing quality processes. We were aiming to cut 20 to 25% off our troubleshooting time. Instead, Caristix software enabled our interface engineers to streamline troubleshooting much more significantly. In one case, what was a 2 hour task now takes just 10 minutes.

“I would also like to [...]

8 Stages in an HL7 Interface Lifecycle

By jeanluc.morin@caristix.com | Published: October 5th, 2010

While clinical end-users count on interfaces to deliver the functionality and interoperability they need, IT stakeholders need to be sure everyone involved gets the steps and costs involved. Especially since interfacing takes up 20 to 40% of an implementation project timeline. Here’s a quick overview to get everyone on the same page.

Meaningful Use Stage 1: Certification is Just the First Step

By jeanluc.morin@caristix.com | Published: September 21st, 2010

Yesterday, CCHIT launched their ONC-mandated test and certification program and delivered a one-hour webcast on their process. Slides and a recording are available on the CCHIT site.

One thing is clear. Certification is just the first step. Certification means that the EHR system or module meets NIST testing criteria for functionality and security related to Stage 1 Meaningful Use measures. But implementation and related integration issues still loom in the background.

At least three objectives in the core and menu sets require [...]

HL7 Interface Conformance Profile Template

By jeanluc.morin@caristix.com | Published: September 14th, 2010

I recently had a discussion with some of our partners around conformance profiles and templates. Collectively, we haven’t come across an industry-standard template. Some organizations build their own. Others decide to go without because templates can take time and effort to set up. We think a conformance profile should help you clearly and concisely communicate what your system expects in terms of data exchange. In healthcare, this isn’t a trivial task. Learn more about conformance profiles in healthcare, which we [...]

What is an HL7 Conformance Profile?

By jeanluc.morin@caristix.com | Published: September 9th, 2010

Definition

Let’s start with the formal definition, introduced by the HL7 organization in the v2.5 specification. Here is an excerpt from section 2.12:

Definition: An HL7 message profile is an unambiguous specification of one or more standard HL7 messages that have been analyzed for a particular use case. It prescribes a set of precise constraints upon one or more standard HL7 messages.

In other words, this is a description of the data and messages that an interface sends and/or receives. The description covers [...]

4 Tips for Smoother HL7 Interface Validation

By sovita.chander@caristix.com | Published: August 17th, 2010

What can you do to improve the HL7 interface validation process on your next implementation project?

I was on-site at a hospital where a vendor was doing a product upgrade. The vendor and the hospital IT team were both committed to getting it done right, so the 2-week interface validation was thorough. That investment pays off. The upfront work pays off down the line in reduced help desk wait time and service calls.

Based on this experience, here are 4 tips to [...]

Application Testing in Healthcare: Sacrifice Test Performance for Traceability?

By jeanluc.morin@caristix.com | Published: August 10th, 2010

There seems to be two conflicting needs in software testing in healthcare: traceability and test performance.

Traceability Traceability is the ability to link your requirements to your tests:

In healthcare, regulatory compliance is on the side of traceability. Reasonably enough, regulators want to know that products actually do what they’re designed to do. Traceability provides that chain of evidence.

Test Performance However, traceability can come at the expense of test performance — defined as how efficiently a product can be tested both for [...]

Gap Analysis in HL7 Interface Deployment, Part 2

By jeanluc.morin@caristix.com | Published: August 3rd, 2010

In Part 1 of this series on HL7 gap analysis, I covered the need to identify gaps before starting to configure an interface, and explained why gaps happen. Today, I’m going to talk about gap analysis steps and the limitations you need to plan for.

Gap Analysis Steps 1. Obtain vendor conformance profile. Vendor analysts start out with an HL7 conformance profile for the product they’re deploying. The profile documents the specific trigger events and segments used by the application. It [...]
