Notes from Healthcare Interoperability 2008

I was in Birmingham yesterday, to join Healthcare Interoperability 2008. I can not say that is was as rich as I had expected, but still it hosted some interesting stands.

EMIS and their partners were the star of the event, and I guess from a business perspective the message was obvious there: primary care is a very good market for healthcare informatics.

I guess it allows you to build controllable products and services. Controllable in the sense that the medical domain requirements you have to handle are much smaller compared to ones in a secondary care institution, and also administrative and financial side of things is again tiny compared to hospital information systems. EMIS certainly knows how to tap into this domain, and their approach to business partners is encouraging. PAERS and EMIS together produce solutions which can take some burden off the shoulders of GP offices. I have to say EMIS people have been very helpful, and they made sure that any questions are answered.

There were some other interesting stands, with some quite specific solutions. I think in terms of healthcare IT, targeting a well differentiated market has huge benefits to offer. You can find a layer that is fit for your resources and you can move between different scales as  a vendor. That is what is missing in some other markets, like Turkey. Being able to produce “to the point” products is a very good option to get into the market, and this model needs to be encouraged. Needless to say, without an established system in primary care, you can not do much.

After the HL7 UK conference

I’ve spend two days of last week at HL7 UK conference, and it was worth it. It was nice to see what are the hot topics in the HL7 domain, and some topics seemed to be a real focus of interest from the community.

A couple of thoughts about the feel of things: first of all, CDA is getting stronger. People are more focused on CDA than any other method for messaging, and this is supported by NHS’s choice to use CDA for messaging. However, HL7 community may like to  consider thinking about  why people are so focused on CDA, when they have a huge amount of work channeled into building models based on the RIM. I mean, CDA has  a more controlled environment of (kinda) its own, and that seems to take a lot of attention.

This was the conclusion I reached a couple of years ago, when I first started about how to implement the national project in Turkey, and I can see that more or less everyone is going towards the same direction now. I consider this as a signal for HL7 people all around the world to take a good look at the modeling practices and approaches people are taking. If people do prefer CDA due to its simplicity, than there is something wrong with the other parts of the work.  In general, I have doubts about the modeling approach of HL7 V3, especially about the specialization practices in RIM based modeling. Throwing away attributes from parent as you descend from it, is not a good fit with the object oriented technologies, which will be a problem in case you want to reflect RIM to a JAVA ITS.

Work around the tooling efforts seem to go in a better direction, and the demo of the Eclipse based modeling solution was nice. I’l like to know how that will end up. I guess RIMBAA is another important initiative to follow, but in general I do not think I am happy with the offered solution. I somehow feel that it will bring more trouble than it eliminates, especially due to work that will be necessary for integration with the local system

Seeing OpenEHR discussed in the event was nice, and listening to Dipak Kalra was even nicer. HL7 is a messaging standard, that’s how it is defined, but what happens after the message arrives is another huge question. OpenEHR has answers for this question, and I guess it would be nice if HL7 domain would also consider the phases after successful messaging.  There is more to write about the whole thing, especially about terminology and information models relationship, but that is another thing that deserves its own post.

To the occasional spammer

Dear friend(s),

I have no idea why you may hope that this little piece of blog will make you rich through the garbage you keep posting on, but I will not loose a minute of my time thinking about it.

I’ve closed all comments thanks to your endless desire to fill my blog with meaningless crap, and now you can go somewhere else.  Maybe I’ll take the time in the future to implement a decent spam filter to get rid of you, but for the moment, you’ve made me choose a blunt mehtod. Way to go!

Note to self, for Eclipse problem (Ganymede under Ubuntu)

When you see an empty dialog just after the splash screen, first check the .log file under workspace/.metadata/

if it is a xul error, which probably is, then do this:

sudo apt-get install xulrunner

append to eclipse.ini
-Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner/xulrunner

(taken from : http://sandakith.wordpress.com/2008/07/11/eclipse-ganymede-startup-problem-in-ubuntu-orgeclipseswtswterror-xpcom-erro/)

Remember: the -D… stuff goes last in eclipse.ini

Mobile 3G, the biggest lie of all

Ok, this blog has been a place of ranting for the last couple of days, but I won’t keep this one inside: my 3 mobile connection is terrible. Others using Vodafone, T-Mobile etc has not mentioned about any positive experiences either.

It appears the mobile operators are enjoying the huge amount of customers buying mobile broadband(!), but are not keen to invest for proper infrastructure to provide the advertised speeds. So far the best my connection has given me is about 30-40 kbs/sec, and that’s when everybody else goes to sleep. 90% of the time however my connection is around 6-10 kbs/sec. Yes, kilobytes! I have not been using such a slow connection since what, 1996?

In case you are planning to get any of these things, think again! On the other hand, the performance of mobile phones is clearly better. I can see people watching videos over their phones, and they do not even have the latest and greatest technogy that we are supposed to have. This makes me think that the operators are capping mobile 3g connections. I wonder what yould happen if a sim card sold in a phone would work in a mobile usb modem?

Very sad state of Eclipse GUI designers

I have just realized that the VE (Visual Editor) project does not support Eclipse versions above 3.2. Moreover, the project seems to be dead, and even if there are a few people who seems to be active in the project mail list, the overall look scene is not very promising.

I am just starting a new project which will be open source, and it will use Java Swing for the UI. There is simply no free UI designer that I can use for Eclipse 3.3 or 3.4.

Matisse4MyEclipse is supported by MyEclipse (I’m one of their customers) and Instantiations have their very impressive Window Builder product. However, none of these give me the ability to just put my source online so that other people can download it and play with it using the same set of tools that I’ve used. Eclipse has become a very solid and rich platform, but UI designer functionality is in a very sad state.

Just because of this, I’ll have to use Netbeans, because I can not expect people to hand code Java Swing UI in the year 2008! Instantiations provides open source licences, but this would not allow people who download my code to use the same set of tools (I guess)

As a result, whatever I do will have to be done on Netbeans instead of Eclipse only because of this situation. I cant’ believe that there  is no single free UI designer for Eclipse now.

London

The title is simple, but means a lot for me at the moment. I’ve moved to London for starting a PhD in University College London, CHIME. It took a a lot of steps, it took quite a lot of time, and there is a lot that must be done here.  This is a short entry, for I have no idea how to talk about this change in detail. So many things to say…
