Inclusive approaches to involvement of community groups in health research: the co-produced CHICO guidance.

Background: Racially marginalised groups are underserved in healthcare and underrepresented in health research. Patient and public involvement and engagement (PPIE) is established as the method to ensure equity in health research. However, methods traditionally employed in PPIE can lead to the exclusion of some communities and exacerbation of existing inequalities, highlighting the need to develop inclusive processes for more inclusive community involvement in health research.
