Lay summary
The Clinical Practice Research Datalink (CPRD) is a repository of primary care electronic healthcare records in the United Kingdom (UK). CPRD collects anonymised patient data from a network of general practices across the UK. Primary care data from CPRD can be linked to secondary care data from Hospital Episode Statistics (HES) in England. Both CPRD and HES have the ability for ethnicity to be recorded in a patient record.
Technical summary
This study will be a retrospective cohort study of completeness and representativeness of the ethnicity recording in the Clinical Practice Research Datalink (CPRD) GOLD and Aurum databases. Additionally, ethnicity recoding in English secondary care, from the Hospital Episode Statistics (HES), will be linked to English patients in CPRD GOLD and CPRD Aurum for a more complete picture of the completeness and representativeness of ethnicity.
