For the 2012-13 financial year, Hospital Episode Statistics (HES) has collected over 17.7 million records detailing episodes of admitted patient care delivered by NHS hospitals in England. These records include details of each delivery which takes place in an NHS hospital. This information has been published in recent years in an annual statistical bulletin.

This is the fifteenth bulletin that has been published on this subject. It covers the period from April 2012 to March 2013 and draws on over 671,000 detailed records of deliveries in NHS hospitals. 


NHS Maternity Statistics, 2012-13

The 2012-13 NHS Maternity Statistics tables have been re-designed to deliver a more consistent layout, where each key variable is analysed by a number of relevant variables.  The key variables are:

Method of onset
Method of delivery
Age of mother
Delivery complications
Birth complications


Provider-level analysis, 2012-13
The purpose of the provider-level analysis is to contribute to the improvement of both the quality and coverage of maternity data submitted to HES.  It is hoped this will stimulate discussion and ultimately contribute to enhancements in patient care.

The provider level analysis provides information at national, strategic health authority and hospital provider level relating to: 
Gestation period in weeks at first antenatal assessment date
Gestation length at delivery
Method of onset of labour
Method of delivery
Person conducting delivery
Place of delivery
Selected Maternity statistics
Spontaneous deliveries with a procedure to facilitate delivery (including episiotomy)
Caesarean with postnatal stay 0-3 days
Total caesarean with anaesthetics
Unassisted deliveries

Please note that an additional data quality note relating to gestation length at delivery was added on 13/01/2014.
