Maternity Services Data Set


The Maternity Services Data Set (MSDS) collects information on each stage of care for women as they go through pregnancy.

The Maternity Services Data Set (MSDS) Information Standards Notice (ISN) that mandates the national collection of the MSDS is available via the former ISB web pages. A corrigendum which makes some minor corrections to the original ISN is also available on the Standardisation Committee for Care Information (SCCI) web pages.

The ISN required that maternity information systems must be fully conformant with the standard by 1 November 2014. Maternity Service providers must collect data locally from 1 November 2014, and central submissions commenced from 1 June 2015 (for April 2015 data).

Version 2.0 of the Maternity Services Data Set (MSDS) is currently in development. The Information Standards Notice (ISN) is due to be published in September 2018, with go live planned for April 2019 (dates subject to change based on approval timeframes). We will keep stakeholders updated via the MSDS monthly newsletter.

What data is collected?

The Maternity Services Data Set (MSDS) sets out national definitions for the extraction of data for:

  • routine booking appointment activities
  • maternity care plan
  • dating scan
  • antenatal screening tests
  • structural foetal anomaly screening
  • labour & delivery
  • newborn screening
  • maternal or neonatal death

The MSDS provides a national standard for gathering data from Maternity healthcare providers in England. It covers key information captured from NHS-funded maternity services.

This data set standard will be used both locally and nationally to generate 'secondary uses' information, i.e. for a purpose other than direct clinical care.

The MSDS will provide reliable information for:

  • payment of Maternity Services
  • local and national monitoring
  • reporting for effective commissioning
  • monitoring outcomes
  • addressing health inequalities

Who should implement the maternity data set?

The MSDS should be implemented by all NHS-commissioned Maternity Services in England who have electronic data collection systems, including acute trusts, foundation trusts and private services commissioned by the NHS. The maternity care pathway covers antenatal, intrapartum and postnatal/postpartum episodes.

When do I need to implement the data set?

System Suppliers

From 01 November 2014, Maternity systems MUST be fully conformant with this standard.

Care Providers

From 01 November 2014, providers of NHS-funded Maternity Services MUST be able to collect information locally, and from 01 June 2015 MUST begin submitting MSDS submissions in accordance with this standard.

How do I implement the data set?

All providers should be discussing the MSDS with their system suppliers to make sure that any required upgrades have been made in accordance with the timescales in the ISN (ISB 1513 Amd 45/2012). If necessary, you should also be making any business changes to data collection processes to ensure that all data items are recorded and can be extracted.

The MSDS is submitted using an XML format. The XML schema has been developed along with a conversion tool, which enables providers to load or copy their data into the provided table structure. Once populated, the tool is able to export the data in the required XML format, ready for submission to the Bureau Service Portal. The associated XML schema is available on the NHS Data Model and Dictionary website. The XML schema is fully supported and any enquiries should be forwarded to with the subject of 'MSDS XML Schema'. The conversion tool pack is available on request. Please ensure that you are using the most up to date version of this, currently v2.4.

In order to start making submissions, you will also need to register to use the submission portal and supply a data user certificate (DUC) form, which you can find under the 'Maternity and Children's Data Set (MCDS)' heading on the NHS Digital Bureau Service Portal web pages . Any queries regarding registration should be sent to the Exeter Helpdesk via

How do I submit the data?

For each reporting period, data providers should populate their XML schema file with data collected from their own local systems and upload this to the central system, using the online Bureau Service Portal (BSP). You will need to register to use the BSP via the Exeter Helpdesk.

During the two month submission window, sites can make as many submissions as are needed. Any files submitted to and accepted by the BSP overwrite previously submitted files. It is therefore imperative that providers thoroughly check their data submission as there are no opportunities to re-submit data for a time period once the portal has closed.

Please note that no concept exists of primary and refresh submissions.

Please also check that you have not marked your file as 'not for submission'.

Once the window closes the 'last good file' present will be made available for national analysis and reporting.

Submissions for each fixed period are made up of data for the appropriate reporting periods.

What are the submission dates?

Data submissions for Maternity Services are based upon fixed period reporting. There is a period of approximately two months for each submission to be undertaken. Data submissions are required on a monthly basis, the timetable for which is shown below.

There was a change in this timetable between 1 January to 28 February 2018 when the submission window  opened for both November and December 2017 data.

Additional data submitted by providers is published within the Maternity Services Monthly Statistics, England reports.

These statistics are initially badged as Experimental Statistics, meaning that they are new Official Statistics undergoing evaluation. They are published in order to involve users and stakeholders in their development and as a means to build in quality at an early stage. Each publication includes a standard Data Quality (DQ) Report that provides an overview of DQ in the MSDS dataset. A variety of DQ dimensions are shown and presented by individual data quality metrics and individual providers.

The following additional documents and tools will assist in implementing the MSDS in your organisation.

Organisational assessment and planning tools

Maternity Implementation Planning Template

You can use this planning template to plan your organisation's activity for implementing the MSDS. The resulting plan should give a high level picture of how your organisation intends to tackle this implementation within the anticipated timescales.

MSDS Readiness Assessment tool

You can use this readiness assessment tool to measure your organisation's MSDS implementation progress. This spans a baseline assessment, regular reviews and a final review to report successful implementation.

XML Extract Schemas

The xml schemas describe the structure of the exports and can be used to assist in development of in-house analytical and checking tools. You can download the XML Extract Schemas from the TRUD website here. In order to access the schemas, you will be required to register with the website and subscribe to each extract. You will be notified each time there is an update and you can further manage your subscriptions from your TRUD account.

The document below details the requirements for forming extracts of data for the Maternity Services Data Set (MSDS) from the Bureau Service Portal (BSP).
