Just one other comment on context linking. We have done a context link between our old McKesson RIS (due to be replaced soon) with ICE. There is an icon on the top tool bar of RIS which says "ICE". Click on this gives us the blood & other results on a web-page for the same patient. I have found this enormously helpful for reporting complex CT/MRI as I can now easily see WBC count, amylase levels, blood tumour markers, etc.
Web technologies doi make context linking far easier that was previously possible & we are able to do this without CCOW.
Getting back to our discussions about HL7 & CDA. Above is some interesting discussions about H7 & CDA and open vs. closed standards. I think it is an important debate to be had. Thanks to David for opening this up for a debate. I had tried to get someone from CFH who would give an opinion on this issue at the Autumn, but they do not wish to express an opnion until cabinet office have reached a decision.
In my google surfing for information, i camne across this http://www.healthstory.com/standards/standards.htm CDA does bring radiology reports in line with other clinical documents exchanged between healthcare professionals. However, I do worry about a closed HL7 standard hampering innovation by the small innovative vendors.
Another worrying development has been that on the Canada Infoway project, general & complimentary membership as part of the HL7 affiliation has been suspended. Vendors have to apply for premium membership to access HL7 material--until an agreement on affiliated membership is reached. I am trying to contact someone from Canada Infoway to shed some light on this & perhaps speak at our meeting.

The HL7 CEO has just announced that it will be changing its policy to become an Open Standard.
Access and implementation will become free by Q1 2013.
This means that using CDA will not require implementers or users to become HL7 members.

To be honest, I don't know whether this is good news or not, but suspect the question is...'what will be the impact on the 'standard'? Will it be a better standard (because its free)? or will users drift away (?because no-one owns it)??
maybe only time will tell.....

This is excellent news for health informatics industry. Thanks David for keeping us updated on this issue.
John, Both DICOM & IHE are dependent on HL7. So HL7 is only going to stay as one can see the imcreasing popularity of IHE amongst vendors.
I feel it is great news - although the page on the HL7 web site is only really a statement of intent so given the devil is always in the details there is much to watch for but a giant leap forward regardless.
John.. It shouldn't have any effect on the integrity of the standard.. like any Open Source software published under free license, there is no transfer of copyright or ownership* (indeed the HL7 page explicitly mentions that), and the direction and development of the standard remains in the same hands - those who have taken up HL7 membership. What I think it should do is remove distractions and give us a platform to bring Health Informatics generally into the twentieth twenty-first century :-)
* obviously some OSS does exactly that but HL7 are not likely to follow that lead.
