This is the fourth annual report on NHS Maternity Activity which brings together established HES data with data from the MSDS which is a maturing, national-level dataset which has been impacted in terms of non-response from providers as they work towards establishing their reporting flows.
For data in 2019-20, the MSDS transitioned to a new version of the dataset. MSDS v2.0 is an update to the existing data set that introduces a new structure and content, including clinical terminology, in order to meet current clinical practice and incorporate new requirements. This is the first publication of data from MSDS v2.0, therefore data from this year is not directly comparable to previous years. More information about the changes for MSDS v2.0 can be found here.
This section reports on the similarities and differences in terms of coverage and nature of reported activity between both data sets.
Both the HES and MSDS record some core data about each delivery and pregnancy including method of delivery, onset of labour, gestation at delivery and gestation at the first antenatal assessment / booking appointment.
