HES Maternity (HESAPC_MAT) Dataset#
Last modified: 29 Jul 2025
1. Summary#
This dataset is a subset of the HES Admitted Patient Care (APC) dataset. Maternity data are also collected in the Maternity Services Data Set (MSDS). Some measures are available in both (e.g. ethnicity of the mother and the baby’s birth weight) and some are unique to one specific data set (e.g. only the MSDS collects the mother’s smoking status and the first feed information, while only HESAPC_MAT collects the length of hospital stay and the number of babies delivered per pregnancy). In reports, HESAPC_MAT data are used for the national totals, because they have historically been more complete.

4. Documentation#
We are currently building a documentation storage system which will host useful documents related to datasets and data owners. We will surface these documents on Guidebook.
5. Useful Syntax#
Below we will include syntax that may be helpful to other researchers in the UK LLC TRE. For longer scripts, we will include a snippet of the code plus a link to the UK LLC GitHub repository where you can find the full scripts.
