General description

This data is derived from the Maternity Indicators dataset which is provided to the Welsh Government by Digital Health and Care Wales (DHCW).
The Maternity Indicators dataset was established in 2016. It combines records from a mother’s initial assessment with a child’s birth record and enabled Welsh Government to monitor its initial set of outcome indicators and performance measures (Maternity Indicators) which were established to measure the effectiveness and quality of Welsh maternity services.
The Maternity Indicators dataset allows us to analyse characteristics of the mother’s pregnancy and birth process. The process for producing this data extract is complex largely because there can be multiple initial assessment data and records for both initial assessments and births are not always complete.
Full details of every data item available in the Maternity Indicators dataset are available through the NHS Wales Data Dictionary: http://www.datadictionary.wales.nhs.uk/#!WordDocuments/datasetstructure20.htm

The mental health conditions listed on the record are categorised as: puerperal psychosis (severe postnatal depression); bi-polar effective disorder/manic depression; psychosis; psychotic depression; schizophrenia; and other (any other mental health condition).

Data collection and calculation

Data from the Maternity Indicators dataset only includes initial assessment data where the initial assessment and birth both occurred in the same health board, in Wales only.
Data should include all hospital births and some home births; however, due to the way data is recorded, we are unable to distinguish between home and hospital births in some health boards. Births to Welsh resident mothers who gave birth in England or in any other country outside of Wales are not included in the data.
Data for each calendar year refers to when the baby was born for both birth and initial assessment statistics. Initial assessments may have taken place in the previous year but would be counted in the year in which the birth occurred. This ensures data throughout a single pregnancy is recorded in the same year.

Revisions information

The Maternity Indicators dataset is a live database, meaning health boards can amend data for any period. For this data, DHCW take data extracts from a single point in time, for the latest calendar year. This means that if data extracts are taken for previous time periods, they may differ to the data which is published as it may have been revised by health boards. Welsh Government will not make revisions to historical data unless errors are discovered.

Statistical quality

From 1st April 2019 health service provision for residents of Bridgend local authority moved from Abertawe Bro Morgannwg to Cwm Taf. For more information see the joint statement from Cwm Taf and Abertawe Bro Morgannwg University Health Boards (see weblinks). The health board names have changed with Cwm Taf University Health Board becoming Cwm Taf Morgannwg University Health Board and Abertawe Bro Morgannwg University Health Board becoming Swansea Bay University Health Board.
Data for Abertawe Bro Morgannwg and Cwm Taf are available for previous years in this table by selecting the tick boxes in the Area drop-down box.
More detailed information on the sources of data and analyses in this statistical release are provided in the quality report: https://www.gov.wales/maternity-and-birth-statistics-quality-report

The Wales-level percentage for pregnant women reporting a mental health condition at initial assessment excludes data from Betsi Cadwaladr and Cwm Taf/Cwm Taf Morgannwg because of their low reliability for all six years. While 99% of records had valid data entered in both health boards, the large majority were recorded as having no mental health condition which is unlikely to reflect the actual position in these health boards.
All other health boards have valid data for the mental health data item in at least 88% of records in each year, apart from Cardiff and Vale in 2016 (56% completeness). In 2024, Aneurin Bevan have been excluded from the mental health at initial assessment analysis due to high levels of missing data (76%).
For 2016 to 2023, the Wales total represents data from 5 health boards. Excluding data from Betsi Cadwaladr and Cwm Taf/Cwm Taf Morgannwg because mental health data recorded is of low reliability. A Wales total is also not presented for 2024 due to excluding 3 health boards from the data analysis (these plus Aneurin Bevan).
The percentages for the number of pregnant women reporting a mental health condition at initial assessment are based on all records minus records with a ‘not stated’ value for mental health condition. The number of records removed from the calculation can be found in Table 4 of the Maternity and birth statistics: quality report tables (https://www.gov.wales/maternity-and-birth-statistics-quality-report).
