well, a "secondary" use - clinical patient care is the "primary" use;-) 
(sorry - just had to say that since it is in most papers, projects you 
will find on the EHR). But I agree largely - you can't have big 
epidemiological or research queries from the CDC or somewhere killing 
your production hospital database  - that's what data warehosing is for 
- transforming data for efficient population querying , and separating 
out the resources for the primary production use of the information from 
all other uses..
