Consulting groups provide access to a petascale data warehouse of over 170 datasets. This includes clinical data gathered by Stanford itself, as well as a variety of population health datasets.

Stanford Clinical Data

STARR, a research data repository with 20 years of fully identified clinical data (since 1998),  includes, but is not limited to, nightly clinical data, Epic Clarity, from both Stanford Health Care (SHC aka adult hospital) and Stanford Children’s health (SCH aka Lucile Packard Children’s Hospital or LKSC). There have been several changes in the Electronic Health Record systems at the Hospitals over the years:

  • Legacy EMRs at SHC before 2008
  • Legacy EMRs at SCH before 2014
  • Epic Clarity at SHC since 2008
  • Epic Clarity at SCH since 2014

STARR contains not only fully identified and up-to-date (within the last 24-36 hours) Epic data from both SHC and Packard but also fully identified and current imaging data from Radiology as well as some historic clinical data from earlier EMRs that is not present in the current EMR systems.
