Comparison of Data Common to HES and MSDS

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.

Comparison of deliveries

The MSDS is a maturing data set and reporting coverage continues to improve. However it does not yet capture as many deliveries as are recorded in HES.

Download the data for this chart Deliveries in MSDS as a percentage of HES deliveries, 2016-17 to 2019-20.

The proportion of deliveries in the MSDS compared to HES was 58.7 per cent in 2019-20.

In 2019-20, the MSDS transitioned to a new version of the dataset, meaning the data from this year is not directly comparable to previous years.

Deliveries by method of onset

The proportion of deliveries with each of onset of labour method is very different between HES and MSDS. This may be related to the significant number of providers that did not submit birth data to MSDS during 2019/20
