Red Hat Group

The Red Hat Group (RHG) was formed at the COMET VII meeting in Amsterdam in 2018, and comprises several initiatives related to improving choice of outcomes in health research – COMET, OMERACT, CS-COUSIN, GRADE, CMTP, COSMIN, CDISC and SONG.


The initial objective is to work together on a project to share knowledge and understanding of mechanisms to promote uptake of COS in comparative effectiveness research.
