National Maternity and Perinatal Audit (NMPA) Data Flow Summary

The National Maternity and Perinatal Audit (NMPA) in England, Wales, and Scotland receives various datasets for maternal and perinatal care, including mortality data, birth notifications, maternity services data, and more. The datasets are pseudonymised and used for linkage, validation, case ascertainment, and longitudinal analysis. Data controllers include Office for National Statistics (ONS), NHS England, Digital Health and Care Wales (DHCW), National Records for Scotland (NRS), and Public Health Scotland (PHS). The NMPA processes and outputs anonymised and aggregated data for reporting, benchmarking, audit reports, and research. Access to specific datasets is regulated, and the data flow supports various analyses and quality validations in maternal and perinatal healthcare.
