Summary

The Aberdeen Maternity and Neonatal Databank holds data for all Aberdeen City births from 1949 to the present day. From 1951 to present this unique database links all the obstetric and fertility-related events occurring to women from a defined population.

Documentation

The Aberdeen Maternity and Neonatal Databank (AMND) was initiated in the department of Obstetrics and Gynaecology, University of Aberdeen, in 1950, by the late Professor Sir Dugald Baird, in collaboration with the Medical Research Council’s (MRC’s) Medical Sociology Unit. It was originally set up as a resource for the study of the physiology, pathology and sociology of pregnancy, but the usefulness of the AMND has extended significantly beyond this through linkage with other health and social care records as well as intergenerational and family linkages.

The AMND is an invaluable resource for life-course epidemiology, especially since it is one of the earliest and most comprehensive obstetric databases. From the year 1950 to the present, this unique database has been recording all the obstetric and fertility-related events occurring in women residing in Aberdeen, Scotland, UK.

Data are collected from every pregnancy event occurring in Aberdeen Maternity Hospital which is part of the National Health Services (NHS) Grampian.

Aberdeen Maternity Hospital is the only maternity hospital in the city of Aberdeen and serves the Grampian region as well as the Northern Isles, Shetland and Orkney, for tertiary maternity care. A dedicated midwives’ unit also based at the hospital provides shared maternity care for uncomplicated pregnancies. The hospital provides antenatal and postnatal care, with about 4000–5000 babies born every year. In addition, an early pregnancy unit based at the hospital manages complications such as miscarriage and other pregnancy loss. The AMND also captures data from these units.

The AMND population coverage varies according to different areas. It covers about 99% of Aberdeen and about 97% of the entire Grampian region. This differential coverage is due to a small proportion of home births and deliveries in peripheral hospitals.

Patient pathway description

The dataset contains information relating to pregnancies and deliveries. The main data items include the following information:

  1. Patient.
  2. Pregnancy (from first ante-natal booking).
  3. Summary of labour and delivery.
  4. Baby details
,

delivery and outcome.

Other data items include:

  1. Diagnostic procedures
  2. Operative management
  3. Drugs
  4. Indications for procedures
  5. Intergenerational data
  6. Datasets from previous studies
  7. Neonatal data

Information is recorded for both Primary and Secondary care (from initial scans through to delivery).

The full patient pathway is recorded from family details (patient

, husband, mother, father) through to techniques used during delivery, and patient/baby health following delivery.

Access service description

The Grampian Data Safe Haven

The Grampian Data Safe Haven (DaSH) is a secure, virtual healthcare data analysis and storage centre established by the University of Aberdeen and NHS Grampian to allow for the secure processing and linking of health data for the Grampian and Scottish population when it is not practicable to obtain consent from individual patients.

The DaSH Research Coordinators can provide advice and support with obtaining the required approvals for DaSH projects. A Permissions Pathway guide explaining the approvals process for DaSH projects is also available. In addition, DaSH have some template application forms with pre-populated information about DaSH that can be used by researchers during the permission application process as appropriate.

DaSH technology ensures unconsented healthcare, social data and other types of sensitive data are accessible for research and clinical purposes whilst protecting individuals’ privacy. Our ethos is built on working with clinicians, researchers and industry partners to improve health and social care by providing a safe and secure environment and enabling cutting-edge research.

The Grampian Data Safe Haven offers bespoke data storage, processing and linkage services based on the individual needs of your research project. The DaSH team works with researchers to provide detailed project planning and data management support whilst ensuring adherence to the highest standards of security and governance and protecting patient confidentiality.

Each project is supported by a Research Coordinator and Data Analyst to ensure projects adhere to permissions and outputs meet the project specification and comply with information security regulations. If you require non-DaSH held datasets, we can assist with obtaining the relevant approvals, as well as coordinating the request with the data custodians and linkage between datasets.
