User Expectations

CADR expects that investigators will be aware of the potential difficulties of working with very large datasets. We suggest that you read through the material on the Choosing the Right Database page of the CADR website.

Spotlight

The Truven Health Analytics MarketScan® Commercial Claims Database has expanded from 5 to 9 years of data (2006-2014)! The MarketScan database is an extremely large, complex collection of individual-level medical and pharmacy claims from private healthcare plans. 

Additions to the AHRQ Healthcare Cost and Utilization Project (HCUP) data inventory include the 2013 National Inpatient Sample (NIS), the 2013 Nationwide Emergency Department Sample (NEDS) and 2014 State data from NY, FL and WA.

The Administrative Data Users group continues to meet on a (mostly) monthly basis.  Information on monthly topics is available here.  Contact CADR at cadr_icts@dom.wustl.edu for more information.
