With appropriate ethics committee and Health Research Authority privacy committee approval, identifiable information was gathered from pre-1994 clinical records and registers for a cohort study of UK patients with insulin-treated diabetes. Identifiers (name and date of birth) were sent to the Office for National Statistics, NHS Scotland, and NHS Digital, who have and continue to notify the study of cancer registrations and mortality (cause and date of death information sources from civil registration data). This data is used for analysis of risk factors for cancer and mortality in the cohort. Appropriate ethics and data protection approval is carried out at all levels in the process.
