This month, a paper giving an overview of the CPRD Aurum database has been published in the International Journal of Epidemiology.
Like CPRD GOLD, CPRD Aurum holds routinely collected primary care data, but collected from practices using a different GP IT system. The paper describes the September 2018 CPRD Aurum build, with over 19 million patients in England, of whom 7 million were alive and currently contributing.
The key strengths of CPRD Aurum are its size and coverage (complementing CPRD GOLD), longitudinal follow-up, representativeness, and standard linkages to national secondary care databases as well as deprivation and death registration data.
Since September, CPRD Aurum has continued to grow and includes additional practices from Northern Ireland. Data held by CPRD in the CPRD GOLD and recently introduced CPRD Aurum databases now encompasses over 35 million patient lives, including 11 million currently registered patients.
