‘Births and their outcome: analysing the daily, weekly and yearly cycles and their implications for the NHS’ was originally funded by the National Institute for Health Research’s HS&DR Programme, Project 12/136/93. We are looking for further funding to complete the analyses.

We are accessing national data about over seven million births, derived from data recorded at civil registration of births and deaths and statutory notification of births linked to Hospital Episode Statistics Data for England provided by NHS Digital, formerly the Health and Social Care Information Centre and corresponding data for Wales, provided by the NHS Wales Informatics Centre. We are using these data to produce statistics in ways which make it impossible to identify you or your child.

The Data Controller is City, University of London, but the data are not stored at the University. They are stored in secure facilities at the Office for National Statistics, which acts as Data Processor. The University of Oxford has also been supporting the linkage work as a Data Processor on behalf of City, University of London. Subject to approvals by City, University of London, ONS and NHS Digital, access to the data may be granted to third parties for independent research. In such cases, they will not have access to identifiable data.

The data

The data consist of individual records from births from January 1 2005 onwards and deaths of these children or their mothers. The records which can be accessed by City staff do not include names and addresses. They include NHS Numbers which are used to link the data and are then removed from the data used for analysis. They also include dates of birth as these are essential for analysis, but data are not released from the secure facilities unless they are in disclosure controlled aggregated tables.

City is working with the Office for National Statistics (ONS), which routinely uses the information collected when a birth or death is registered, to produce statistics about births and infant deaths in England and Wales.

ONS is working with researchers at City, University of London to link this information to data extracted from NHS hospital records of births in England and In Wales. These include information about mothers and babies recorded at birth, such as length of pregnancy, time of birth, method of birth and conditions diagnosed in mothers and babies. This has been further linked to data about any subsequent admissions to hospital of either the mother or the baby after birth. Linking birth registration data to this NHS information will produce fuller information about births and their outcome to analyse for research and statistical purposes to provide more detailed information about the care given at birth than is recorded in any system individually and which can be used to inform decisions about the provision of maternity care.

The questions this information will help us to answer relate to the need to ensure a consistent 24 hour maternity service, which is a high priority. This linked database was set up for a special project to see how numbers of births and maternity care for mothers and babies vary over time and whether there is any difference at night, during weekends or at holiday times. We aim to answer the following questions:

1. How does the number of births vary by time of day, day of the week and day of the year?

2. Does the way labour starts and how babies are born change according to the time of day and the day of the week?

3. Do the size and type of maternity unit and variations in medical and midwifery staffing affect these patterns of birth?

4. Is there any difference by time of day, day of week and time of year of birth in stillbirth and infant death rates or in the extent to which babies or their mothers are readmitted to hospital? If so, does this relate to the length of the pregnancy or how the baby is delivered?

Confidentiality

We are not using individuals’ names and addresses to do this project. The information accessed includes NHS numbers, dates of birth and postcodes. This is being held electronically on a secure system at ONS and access is only given to authorised users. All our project members have a legal duty to keep information about individual mothers and their babies confidential. City adheres to the principles of medical confidentiality. Personal data, as defined in the Data protection Act 1998, the will not be disclosed by City or ONS to third parties except for other authorised researchers who have obtained the necessary permissions. These obligations shall continue without limit in time.

Where to find the results so far

Our report on the project so far will be published by the National Institute for Health Research and a summary will appear on ONS’ web site. A lay summary and other information about the project can be found at https://www.journalslibrary.nihr.ac.uk/programmes/hsdr/1213693/#/ More detailed publications can be found in City Research Online http://openaccess.city.ac.uk/
