CPRD collects fully-coded patient electronic health records from GP Practices using the Vision® or EMIS® software systems. Due to some differences in structure and clinical coding in these two systems, these data are provided as two separate primary care databases at present with accompanying metadata and advice to enable researchers to make study-specific decisions on how best to pool these data.
Our in-house researchers are happy to provide advice on which database to use depending on your research question.
