Abstract

Summary: A major obstacle of evidence‐based clinical decision making is the use of nonstandardized, partly untested outcome measurement instruments. Core Outcome Sets (COSs) are currently developed in different medical fields to standardize and improve the selection of outcomes and outcome measurement instruments in clinical trials, in order to pool results of trials or to allow indirect comparison between interventions. A COS is an agreed minimum set of outcomes that should be measured and reported in all clinical trials of a specific disease or trial population. The international, multidisciplinary Cochrane Skin Group Core Outcome Set Initiative (CSG‐COUSIN) aims to develop and implement COSs in dermatology, thus making trial evidence comparable and, herewith, more useful for clinical decision making. The inaugural meeting of CSG‐COUSIN was held on 17–18 March 2015 in Dresden, Germany, as the exclusive theme of the Annual Cochrane Skin Group Meeting. In total, 29 individuals representing a broad mix of different stakeholder groups, professions, skills and perspectives attended. This report provides a description of existing COS initiatives in dermatology, highlights current methodological challenges in COS development, and presents the concept, aims and structure of CSG‐COUSIN. Abstract : What's already known about this topic? Many different outcomes and outcome measurement instruments are used in clinical trials to assess the benefits and harms of treatments. The use of noncomparable outcome measurement instruments, often with unknown measurement properties, makes the combining of results in systematic reviews difficult. The inability to compare outcomes across trials hampers evidence‐based recommendations and clinical decision making. Core Outcome Sets (COSs) have been suggested to standardize the measurement and reporting of study endpoints. What does this study add? The theme of the 2015 Annual Cochrane Skin Group Meeting was the initiation of the international, multidisciplinary Cochrane Skin Group Core Outcome Set Initiative (CSG‐COUSIN). The mission of CSG‐COUSIN is to develop and implement high‐quality COSs in dermatology to make trial evidence comparable and more useful. The CSG‐COUSIN management team and methods group will develop methodological approaches and standards to optimize the COS development procedure and to guarantee high‐quality recommendations for outcomes and outcome measurement instruments.
