The updated HERC Database of Mapping Studies is now available at https://www.herc.ox.ac.uk/downloads/herc-database-of-mapping-studies.

This includes 38 new studies published before January 2019 describing 82 mapping algorithms: including new source instruments, such as the Glasgow Outcome Scale, Kessler Psychological Distress Scale and 22-item Sino-Nasal Outcome Test (SNOT-22). Version 7 includes a total of 182 studies reporting 386 mapping algorithms, including 42 mapping to EQ-5D-5L. The database can be filtered by disease area or source/target instruments to quickly identify mapping studies that may provide data inputs for economic evaluation and assess the novelty of new mapping studies.
