Abstract

A network data quality check which determines whether there are any value set violations in the submission. Value set violations are values that are outside of an accepted range of permissible values, usually defined in the PEDSnet conventions. For example, visit types in the PEDSnet data model can only contain a series of values that are specified in the conventions document.

Results of this check for the current data cycle can be explored on the PEDSnet Data Quality Dashboard. Data quality results for previous data cycles have been archived in the Valueset Conformance Network Results collection.

Visualization Output

NOTE: Visualizations are NOT part of the packaged code. This description applies to what is used on the PEDSnet Data Quality Dashboard.

The results of this check are visualized as a bar graph displaying ONLY the value sets where violations are present. It will show the proportion of rows represented by the violating concepts where violations are present.

Raw Output

This check produces a raw data output containing 16 columns of data:

Column Data Type Definition
total_denom_ct character the total number of rows in the table
total_pt_ct character the total number of patients in the table
site character the name of the site being targeted
database_version character the database version from which the counts originated
check_name character a short string identifier for the check
check_type character a short string identifier for the module
accepted_value boolean indicator of whether or not the vocabulary is acceptable for that table + field
table_application character the name of the table for which the vocabulary distribution was evaluated
measurement_column character the name of the column in the table_application for which the vocabulary distribution was evaluated
concepts numeric concepts that violate the valueset; defaults to -999 if no violations are found
total_viol_ct character the number of rows with concepts that do not meet the valueset requirements
total_viol_pt_ct character the number of patients with concepts that do not meet the valueset requirements
concept_name character the name of the violating concepts; defaults to “No violations” if no violations
vocabulary_id character the name of the vocabulary associated with the violating concepts; defaults to PEDSnet if no violations

The [Network Data Quality (NDQ)](https://pedsnet.github.io/ndq/) package contains several data quality modules intended to evaluate the overall condition of the data in a clinical research network. These modules, which cover a broad range of data quality domains from conformance to plausibility, are flexible and can be configured to execute checks specific to desired use cases in both the OMOP and PCORnet common data models (CDMs).
