Data resource profile: Clinical Practice Research Datalink (CPRD) Aurum

Abstract

Clinical Practice Research Datalink (CPRD) is a UK government, not-for-profit research service that has been supplying anonymized primary care data for public health research for more than 30 years. In October 2017 CPRD launched a new data resource called CPRD Aurum. CPRD Aurum is a database containing routinely collected data from primary care practices in England, capturing diagnoses, symptoms, prescriptions, referrals and tests for over 19 million patients as of September 2018 ( Figure 1). Primary care data in CPRD Aurum have been linked to national secondary care databases as well as deprivation and death registration data ( Table 1).
