Information systems in medicine tend to be tools.

Trials tend to be of the products.

I can see the possibility of a RCT between two 
decision-assisting algorithms for a single condition, but I 
think one of the larger elements to study will be how th eusers 
like working with them.

Unfortunately at the moment that can very easily be subsumed by 
a discussion of how th epaymasters an get the managmeent 
information they want from the various system components, and 
how they can enforce particular behaviour on users.

Given a few more generations of managers and programs this may 
tilt back, but RCTs are perhaps a subtler instruemnt than fits 
the software we have at present.
