Linked datasets

The latest set of linkage data (set 18) is now available for use in research studies. There has been an increase in the coverage periods for many of the linked data sources.

Linkage data is available for patients from 416 CPRD GOLD contributing practices (based on the Vision software system) and 890 CPRD Aurum contributing practices (based on EMIS software).

Further information about set 18 and how CPRD provides routine data linkages between primary care and other health-related patient datasets is available on our linked data web page.
