So data consistency and integrity is not important in the medical  
domain and the EAV stuff is used as the main model for data  
management? I can't believe that. EAV is just a synonym for "I don't  
like to think about data management and schema evolution, therefore  
let me break it right away in the design phase." Of course, it has  
its uses but it's rare to see it applied properly.

Implementing an EAV pattern on top of Hibernate is trivial. Attached  
some source you may use if you promise never to design a system with  
this that runs my pacemaker.
