HL7 Survival Guide: Chapter 11 Maintenance, Troubleshooting, Monitoring

By sovita.chander@caristix.com | Published: May 30th, 2013

Now we’re coming full circle. Throughout Chapters 6 through 10, we talked about creating interfacing artifacts, assets, and documentation: profiles, gap analyses, test plans, test messages, test systems, and workflow maps. In this chapter, we explain how you can get maximum value from all the work you put into creating all of those. 

Why Document?

By documenting your profiles and specs, you can much more easily troubleshoot issues and tweak configuration once your interface is live. Plus, if you created electronic – [...]

HL7 Survival Guide: Chapter 10 Process and Workflow

By sovita.chander@caristix.com | Published: May 13th, 2013

In the last chapter, we explained what to aim for in test messages and message samples. Next you need to map out your processes and workflows to understand how your interface can support them.

For example, your clinical workflow may look like this: a patient is admitted in the Emergency Department via the departmental ADT system. The doctor on duty orders lab work and the patient is admitted to the hospital. The admission is now recorded as an in-patient in the [...]

HL7 Survival Guide: Chapter 9 Message Samples and Test Messages

By sovita.chander@caristix.com | Published: March 26th, 2013

In the previous chapter, we covered what you need to know when testing your interface. While the right test tool is helpful, you need to feed it the right message samples and test messages. After all, messages impact the entire interfacing lifecycle.

So what makes messages “right”? Namely, you need message samples and test messages that reflect your environment: your ADT message flow, your specific lab codes, and your case mix – whatever information your interface is intended to share.

Just as [...]

By jeanluc.morin@caristix.com | Published: March 5th, 2013

The HL7 interface lifecycle. You need to test during Configuration, Validation, and Maintenance.

In the last two chapters, we covered some of the requirements-related artifacts you need. Now it’s time for testing, which you conduct at different phases in the interface lifecycle: during configuration and development; during the formal validation phase; and during maintenance.

“Why test?,” you ask. When you start to develop and iterate on your interface, you run tests to avoid introducing new problems – you check and test [...]

HL7 Survival Guide — Chapter 7: Gap Analysis

By jeanluc.morin@caristix.com | Published: February 21st, 2013

This chapter helps you set up a crucial HL7 requirements document: the gap analysis. Once you have profiles for your source and destination systems, you need to capture a list of all the gaps existing between the two systems in a requirements document. You unearth this list by conducting a gap analysis, which will tell you what’s missing and what needs to be bridged by the interface. In essence, a gap analysis captures the differences in messaging between the new [...]

The first five chapters of this Survival Guide have helped you think strategically about your interfacing project. Now we’re going to dive into the nitty-gritty of what you need in an interface specification and/or HL7 profile (note: we use the terms specification, conformance profile, and profile interchangeably in this chapter).

An HL7 interface specification should list:

1. Interface name
