Variation in Mother-Infant Linkage Rates by Jurisdiction in U.S. Medicaid Data

Within the U.S. FDA’s Sentinel System, linkage of mother and infant data is critical for the assessment of medication safety during pregnancy. Recently, U.S. Medicaid and Children’s Health Insurance Program (CHIP) data in the new Transformed Medicaid Statistical Information System (T-MSIS) format were converted to the Sentinel Common Data Model, and an initial mother-infant linkage was performed. 

This presentation assesses mother-infant linkage rates by U.S. Medicaid jurisdiction and explores jurisdiction-specific reasons for differential results. It was presented at the 39th International Conference on Pharmacoepidemiology and Therapeutic Risk Management.
