guide to hl7 implementation [closed]

Question

I'm trying to get a handle on hl7 and so far I'm reasonably clear on the data structures and encoding protocols. Where I remain mystified is the actual implementation mechanics e.g. sequence of request, ack, response, ack and such things as do I need to ack an ack etc, what do if I receive a nack/ no ack etc?

Any pointers on where to start looking to learn about these things?

Answer 1

There are a number of resources that can help you with the details of your HL7 implementation. I highly recommend becoming a member of HL7.org as they have the current and detailed implementation guides. You can also find other resources on the web:

1) HL7 v2.3.1 Implementation Guide
Chapter 2 references Acknowledgements specifically.

2) HL7.org Wiki
Here is the HL7 v2 FAQ

I hope this helps.

Answer 2

Interfaceware offer a useful introductory resource on HL7 version 2.

It is also useful to bear in mind that HL7 v2 and HL7 v3 are very different standards, essentially based on different messaging technologies The standard body for HL7, recently freed up some of their license restrictions, making some of their resources available for free.
