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.

 The Cochrane Skin - Core Outcome Set Initiative (CS-COUSIN) is a multiprofessional international initiative that supports the development and implements Core Outcome Sets (COS) in dermatology in order to improve and standardise outcome measurement in clinical trials and to make trial evidence more useful. It is part of Cochrane Skin.

A COS is a standardised consented minimum set of domain and outcome measurement instruments to be used in every trial in a medical field. A core outcome set does not mean that only COS should be measured, but simply that the COS should be measured in all future trials of that particular skin disease so that results can be compared properly. Outcomes that are additional to the COS can be measured as required by the specific study.

CS-COUSIN is the first Core Outcome Set group within the Cochrane Collaboration. CS-COUSIN provides assistance and guidance for the development of COS in dermatology following a structured peer guidance workflow.

Core Outcomes Sets are available or being developed for the following conditions:
