BC Perinatal Data Registry

Description

The BC Perinatal Data Registry (BCPDR) captures maternal, fetal, and neonatal data for an estimated 99% of all births that occur in BC. The BCPDR captures data for both the mother (Delivery episode, Postpartum Transfer/Readmissions ≤42 days) and the baby (Baby Newborn episode, Baby Transfer/Readmissions ≤28 days). The available BCPDR data fields are separated into these four suites below. ≥

For detailed abstraction guidelines and questions about the definitions for specific fields in the BCPDR, please refer to the applicable version(s) of the BCPDR Reference Manual, located at: http://www.perinatalservicesbc.ca/our-services/data-surveillance.
