Linkage to health data – hospital episode statistics

About the research

This research project focused on the value gained by linking study data to health data from the NHS. It explored the types of consent used in Understanding Society and the Avon Longitudinal Study of Parents and Children (ALSPAC), with a focus on linkage between study data and Hospital Episode Statistics (HES). HES is a database containing details of all admissions, A&E attendances and outpatient appointments at NHS hospitals in England.

Researchers can now benefit from a CLOSER resource report to help them link longitudinal data to HES. The project team published a paper in November 2014 in the BMC Medical Research Methodology journal outlining their findings around participant consent to linkage in Understanding Society.
