Abstract
A network data quality check which computes the overlap of patients across more than one domain or clinical characteristic. The combined count in the output is the number of patients meeting both cohort definitions when they occur within a specified time period of each other (i.e. events must occur within 30 days of one another).
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 Data quality results for previous data cycles have been archived in the Domain Concordance Network Results collection.

Visualization Output
NOTE: The visualizations are NOT part of the packaged code. This description applies to the visualizations available on the PEDSnet Data Quality Dashboard.
There are three distinct ways to view the results of this module. The first is a bar graph with the proportion of patients only meeting the cohort 1 definition, the proportion of patients meeting both cohort definitions, and the proportion of patients only meeting the cohort 2 defintion.
The second is a bar graph that uses cohort 1 as the denominator – meaning out of all patients who meet the definition for cohort 1, how many also meet the definition for cohort 2 (i.e. out of all patients with an asthma diagnosis, how many also have a bronchodilator drug exposure).
The third is a bar graph that uses cohort 2 as the denominator – meaning out of all patients who meet the definition for cohort 2, how many also meet the definition for cohort 1 (i.e. out of all patients with an bronchodilator drug exposure, how many also have an asthma diagnosis)

cohort_label |
character | a descriptive label of each cohort |
site |
character | the name of the site being targeted |
database_version |
character | the database version from which the counts originated |
check_type |
character | a short string identifier for the module |
