I have just completed an article on “Leveraging the Computerized Hospital Information System for Medical Education and Research“. It is a concept paper. I do not know if such a system has been implemented anywhere. In the hospital I worked in previously, domains have been created for Operations, Analytical function, Train and Build. However, despite being a hospital for training undergraduates and postgraduates, the benefits of HIS have not been optimized for teaching and learning.
I think there are extensive possibilities and would like to realize them if given the chance.

A PDF version is available.
