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 are linked to many other datasets, including socioeconomic (SES) measures, to provide a fuller picture of health in the UK.
Technical summary
This study will be a retrospective cohort study of completeness and representativeness the area level socioeconomic (SES) and Rural-Urban Classification (RUC) data linked with the Clinical Practice Research Datalink (CPRD) GOLD and Aurum databases, amongst acceptable patients and currently registered patients eligible for patient postcode linkage. SES/RUC data linked with CPRD can be provided at the practice-level across the UK, and at the patient-level for England only. Currently, CPRD offers linkage with the Indices of Multiple Deprivation (IMD), the Townsend Deprivation Index, the Carstairs Index, and RUC, which are commonly used in health research as a proxy for individual level SES in analyses.
