Extending a clinical repository to include multiple sites.
With the consolidation of health care organizations and services, a clinical repository comprising data from a single site is no longer sufficient. Individual patient data are now spread across multiple sites comprising a single enterprise. Users require an integrated view, or at least a common view, of these clinical data across multiple sites. Many issues arise when one tries to merge data from multiple, distinct organizations into an existing schema. We have addressed these issues while extending our clinical repository for Barnes Hospital with data from Jewish Hospital, both of which are members of the recently formed BJC Health System. We describe the architecture of our existing repository, approaches and issues in extending this repository to include multiple sites, and the specific issues we addressed in our system.
