The Sentinel Distributed Database has a total of 351.8 million unique patient identifiers spanning the 2000 to 2020 time period. If patients move between health plans, they may have more than one patient identifier. 228.7 million patients have least one day of drug and medical coverage.
Of those with both medical and drug coverage, there are:
- 70.6 million members currently accruing new data
- 788 million person-years of data
- 14.8 billion pharmacy dispensings
- 13.8 billion unique medical encounters
- 42.6 million members with at least one laboratory test result
Additionally, the Sentinel Distributed Database contains 5.1 million deliveries with a mother-infant linkage.
The Sentinel Common Data Model (SCDM) includes a Mother-Infant Linkage (MIL) table that enables the routine evaluation of medical product exposures during pregnancy on outcomes observed during infancy. Mothers and infants are matched mainly on family subscriber numbers and, when available, birth certificate data. Most matches were deterministic, though probabilistic matching methods were also used by some Data Partners. More information about the MIL table may be found in the Mother-Infant Linkage FAQ.
The Sentinel Distributed Database has:
- 4 Data Partners populating the MIL table
- 5,108,877 linked deliveries
- 78.7% linkage rate
