The Research Data Core (RDC) provides a relational database produced from Tennessee Medicaid and TennCare. The database includes Medicaid enrollment, Medicaid and TennCare professional and institutional encounters and pharmacy records. Medicaid enrollment is augmented with information from birth, death and fetal death certificates through a probabilistic linkage. Medical encounters are augmented with Medicare and Hospital Discharge Data System records.
This database has potential for use in pharmacoepidemiology or program evaluation.
