Import Dates

TPP create a snapshot of the primary care information captured in the SystmOne database; this is processed before it is imported into the OpenSAFELY-TPP database. TPP also receive (or "ingest") external data sources from NHS Digital, ONS, etc. These external data sources are also processed before they are imported into the OpenSAFELY-TPP database. In each case, a new import overwrites the previous import. Once a data source has been imported, it can be queried immediately from Level 3.

The dates in the sections below reflect when the data sources were last imported into the OpenSAFELY-TPP database. They do not reflect when the data sources were received by TPP, nor when the event activity occurred.
