The publication includes details of all births taking place in NHS hospitals (in England) excluding home births and those taking place in independent sector hospitals. This includes a wide range of information such as details of how the baby was born (method of delivery), complications, birth weight and gestation.
This information was historically reported separately from other HES data because it has a number of unique characteristics and issues which do not affect other aspects of the data. More information about these issues can be found in the maternity topic paper on HES online.
