National Maternity and Perinatal Audit (NMPA) Data Flow Overview

The National Maternity and Perinatal Audit (NMPA) collects data extracts from various datasets in England, Wales, and Scotland to improve maternity and perinatal services. The datasets include mortality registers, birth notification datasets, maternity services data sets, and more. The collected data is pseudonymized and used for longitudinal analysis, validation, and benchmarking purposes. The NMPA collaborates with different data controllers and processors to generate anonymized and aggregated outputs for analyses and reporting.
