title: Domain Concordance Results, PEDSnet Database (2025-07)

description: Results vary greatly by site and domain.<br><br> Thirteen threshold violations were flagged in this data cycle: 1. A low concordance between two cohorts. For this check, only 64.2% of patients with evidence of Type 1 Diabetes Diagnosis also have evidence of Insulin Drug Exposure. This is less than the minimum expected value of 70%. <br> Codesets: [Cohort 1](https://pedsnet.org/metadata/handle/20.500.14642/1060), [Cohort 2](https://pedsnet.org/metadata/handle/20.500.14642/1076) 2.

description: This network analysis computes the overlap of patients across more than one domain or clinical characteristic both by year and overall. The combined count in the output is the number of patients meeting both cohort definitions. Proportions are calculated where the numerator is the number of patients meeting the given cohort definition and the denominator is the total number of patients meeting one or both definitions (i.e. patients in cohort 1 + patients in cohort 2 - patients in both cohort 1 and cohort 2). All PEDSnet sites as of July 2025 were analyzed, but site names have been anonymized in this report.
