This section contains detailed descriptions of the data quality
checks included in the DataQualityDashboard package. Each check is
described on its own page; click on the check name in the list below or
in the dropdown menu above to navigate to the check’s documentation
page.
N.B. This section is currently under development. A documentation
page is not yet available for all checks. The links below will be
updated as more pages are added. In the meantime, see the Check
Type Descriptions page for a brief description of each
check.
General guidance
- These documentation pages are intended to provide a detailed
description of each check and guidance for users on how to interpret the
results of each check
- Guidance is provided for both ETL developers and OMOP
CDM users (e.g. analysts, data managers, etc). CDM users are
strongly encouraged to work with their ETL development team, if
possible, to understand and address any check failures attributable to
ETL design. However, guidance is also provided in case this is not
possible
- In some cases, SQL snippets are provided to help investigate the
cause of a check failure. These snippets are written in OHDSI SQL and
can be rendered to run against your OMOP CDM using the SQLRender package.
As always, it is also recommended to utilize the “violated rows” SQL
(indicated by the comment lines
/*violatedRowsBegin*/ and
/*violatedRowsEnd*/) from the SQL query displayed in the
DQD results viewer for a given check to inspect rows that failed the
check
