The International Society For Pharmacoeconomics and Outcomes Research (ISPOR) has put together a database of databases from around the world. The ISPOR International Digest of Databases has goal is to organize global health care databases into searchable models. Their working group on this topic is chaired by Carl Asche and Elisabeth Oehrlein. If you have any databases you suggest that should be added to ISPOR’s International Digest of Databases, you can email the working group with suggestions using this form.
While I have not reviewed the quality of this database in detail, the opportunity to have a single searchable database to identify high value data around the world would be extremely valuable for researchers. The University of Michigan’s ICPSR attempts to the same but focuses on social science more broadly.
Regardless, providing researchers with more information and access on health care tools and data will hopefully greatly improve the quality of social science and health care research in the future.
