I agree partially. It's true that you re-evaluate quality based on  
the feed back that you receive and changing insights (the PCDA cycle)  
but that doesn't mean that it's a moving target. Once a good sense of  
quality is established by all parties involved and the underlying  
insights don't change (f.i. by new lines of research), a quite stable  
situation can occur. Here in the Netherlands we've a lot of  
experience with quality protocols to asses common ailments in the GP  
office. Some of these protocols are stable for over 5 years now. So  
yes the quality cycle is infinite but the work to create and maintain  
such a system not.

I agree, the thing I'm looking/asking for is that we can store  
additional data required for a quality system. I realize that,  
especially in the beginning, quality systems wills only be used in a  
few (sub)processes and probably will never aply to all of them. As  
Ian McNicoll points out,  the cost/benefit factor will kick in there,  
but i totally agree with Thomas that in the end it's all about  
quality of care we provide to the patient/citizen.

Absolutely, thanks,
