MSDW Data Contents

The Mount Sinai Data Warehouse (MSDW) collects clinical and operational data for use in clinical and translational research, as well as quality improvement initiatives.

 

The MSDW provides researchers access to data on patients in the Mount Sinai Health System Epic EHR:

  • Over 11 million patient records
  • Over 87 million patient encounters

 

 

Understanding Electronic Health Record (EHR) Data

Principal Data Architect Timothy Quinn, PhD, has developed informative presentations on OMOP Vocabulary Tables and Electronic Health Record (EHR) Data in MSDW:

Mount Sinai’s Epic electronic health record (EHR) system constitutes the primary data source for the Mount Sinai Data Warehouse. Data are also loaded from other ancillary systems.

 

 

MSDW Data Model

MSDW ecosystem uses the OHDSI collaborative’s OMOP Common Data Model to facilitate optimal data sharing and interoperability both internally (at Mount Sinai) and externally with research partners. The clinical data are extracted from Mount Sinai’s Epic Caboodle database and other ancillary systems, transformed to the OMOP Common Data Model (CDM) format, and loaded to the MSDW database. These data are updated daily.

The MSDW is situated on the Minerva High Performance Computing (HPC) cluster alongside other research data sets.
