C-A1-02: Developing a Structure for Programmatic Quality Assurance Checks on the Virtual Data Warehouse

Abstract

Background/Aims The HMORN Virtual Data Warehouse (VDW) has an expanding set of quality assurance data checks developed by its data content work groups. These checks improve the reliability and consistency of the data across sites. When the Center for Effectiveness and Safety Research (CESR) Data Coordinating Center sought to provide additional data checks, it defined a standard methodology for additional validation. The structure and methodology provides a basis to apply data checks consistently across the data content areas.
