THIN and academic institutions
Academia data

Unique areas in which Academia can have access to include:

  • THIN Research Services: GP Questionnaires, Patient Questionnaires, Redacted notes from Electronic Health Records, Death Certificate analyses.
  • Affecting Change through Cegedim’s Outcomes Manager solution which is system agnostic. This allows critical research to be put into practice where change can be affected at the patient or clinician level.
  • Clinical Trial scoping, development and implementation – utilising data from THIN in addition to Cegedim’s Outcomes Manager solution.

Data Governance

The THIN® Advisory Committee provides advice on the operations of the database, to ensure that it continues to be used in a way that maximises its research value in the best interests of the public whilst protecting the rights of its data subjects.

Our Advisory Committee meets three times each year, or as needed, and consists of representatives from the following organisations and roles:

• THIN® management employed by Cegedim

• Data scientists and epidemiologists from THIN® academic partners

• NHS clinicians, including general practitioners

• Patient representatives

Real World Evidence - how is THIN data used for research?

The collected Real-world Data is used mainly to carry out studies including scientific and statistical studies, producing Real-world Evidence to inform research. This can either be directly by THIN® or by a third-party entity to whom the data is transmitted in anonymised form. These studies are mainly intended for the Life Sciences sector, the medical and academic world as well as research centres.
