Generalized Review of OSCAR Unified Checking (GROUCH) is a program that produces a summary report for each data source of warnings of implausible and suspicious data observed from the OSCAR summary. It identifies potential issues across all OMOP common data model tables, including potential concerns with all drug exposures and all conditions. GROUCH allows for data quality review of specific drugs (such as the ingredients that comprise the OMOP drugs of interest) or specific conditions (including population-level prevalence of the health outcomes of interest, and unexpected gender-specific rates, such as males with pregnancy, and females with prostate cancer).
The GROUCH Specification and source code are available. Click on the document titles below to obtain the following:
