Our data


THIN data is a UK primary care electronic medical record (EMR) data resource covering more than 3.7 million active patients. These patients are representative of the UK population by age, gender, medical conditions and death rates adjusted for demographics and social deprivation.

The collected records (EMR) are consistently updated and can be followed as they develop over time. The GPs contributing data to THIN provide health services under the terms of the UK’s National Health Service (NHS).

The unique nature of the UK’s NHS allows the life-long health record of a UK citizen to be held by one practice. THIN provides a comprehensive picture of pseudonymised patient data including:

  • Diagnoses
  • Pseudonymised commentary written by the health physician
  • Symptoms
  • Prescriptions issued
  • Tests and results
  • Measurements and readings taken in the practice
  • Demographic information
  • Dates of entry in and out of the database: These dates include information on death and outcomes of conditions and treatments.
