The Virtual Health Information Network (VHIN) assists researchers to do high quality health research using Integrated Data Infrastructure (IDI) and other administrative health data.

A deeper understanding of the IDI and increased awareness of data quality issues can be gained via online guides, discussions on the VHIN Facebook page, analytical code from VHIN research projects and our shared code repository, explanatory material from meetings and presentations about current IDI research, and courses.
