Data Cycle Change Results, PEDSnet Database (2025-07)

1. **Homogeneous changes**: The overall changes observed from the previous data cycle (database version 5.7) are largely homogeneous, with nearly zero proportional change between cycles. 2. **Threshold violations**: Seventeen threshold violations were flagged in this data cycle. These violations indicate changes in count between data submissions that exceed acceptable limits. 3. **Domain-specific issues**: The threshold violations are specific to certain domains, such as Immunization, ADT, Device Exposure, and Drug Exposure. 4. **Negative proportional change**: There is a significant negative proportional change (-80%) observed in the Immunization domain data from a single site. 5. **Positive proportional changes**: Positive proportional changes are observed in ADT data from multiple sites (ranging from 18% to 23%). 6. **Maximum acceptable changes**: The maximum acceptable changes for these domains are -5% and 15%, respectively. In summary, the data quality results indicate that there are some concerns regarding changes in count between data submissions, particularly in certain domains such as Immunization and ADT. These threshold violations may require further investigation to ensure the accuracy and integrity of the data.
