Core Outcomes Set Initiative (CS-COUSIN)

The CHORD COUSIN Collaboration

The Consortium for Harmonizing Outcomes Research in Dermatology (CHORD) and the CS-Core Outcome Set Initiative (CS-COUSIN) groups have formed a union that has brought together a global network of stakeholders engaged in core outcome set (COS) development for dermatologic conditions under one organizational structure known as C3: CHORD COUSIN Collaboration. C3’s vision is the improved health of patients through robust assessment of interventions in dermatology, skin care and related areas. The mission is to develop, disseminate and implement Core Outcome Sets (COS) for clinical trials and routine care through the engagement of patients, clinical experts, methodologists,  industry partners and other possible stakeholders. Find out more on the C3 website.


Jochen Schmitt and Hywel Williams initiated the international, multidisciplinary Cochrane Skin Group Core Outcome Set Initiative (CS-COUSIN) in 2014. With energy and enthusiasm the international community agreed to collaboratively work on the aim on development, quality assurance, implementation, and dissemination of core outcome sets in dermatology.
