I’m ginvg a talk about i2b2 (among other things) and when browsing through their website, I cam across an interesting project, SHRINE. This is an acronym for Shared health Research Informatics NEtwork., and represents a way of allowing users to review information across multiple i2b2 sites. It requires the individual institutions who have i2b2 systems to cooperate with one another, which is not always easy. But this has tremendous potential.
