Aims and mission    Who we are    Methods group    Project groups    Management group

In the field of dermatology 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.

Aims and mission

  • to support the development and to strengthen the quality of core outcome sets (COS) in dermatology
  • to standardize the selection of domain and outcome measurement instruments in dermatology clinical trials to make trial evidence more useful and comparable
  • to strengthen the quality and interpretability of systematic reviews in dermatology through the implementation of COS in trials and reviews
  • to strengthen the quality of evidence-based decision making in clinical practice and eventually the quality of care for dermatology patients.

Who we are

Jochen Schmitt and Hywel Williams founded CS-COUSIN in 2014. Jochen is the current lead of the Initiative. CS-COUSIN consists of a Methods Group, several Project Groups and a Management Group.


Management group

Based in Dresden, Germany, it oversees and facilitate the progress of the groups through COS development. It holds key advisory documentation, publications and databases. It maintains contact with Cochrane Skin (UK) and supports Project Groups with literature searches.

Methods Group

This consists of 9 experienced post-doc or professorial experts in the development of Core Outcome Sets. Each Project Group is assigned one of these advisors who remains with them for the lifetime of the project.

The key research interests of Jan Kottner are skin and tissue integrity and preventive skin care with a special focus on skin physiology, skin barrier restoration and maintenance as well as efficacy of skin care interventions and pressure ulcer prevention. He has also special interests in evidence-based practice including systematic reviews, clinical trial design and conduct, and outcome development and validation. Since 2015, he works within CS-COUSIN and is member of the Core Outcome Set in the Incontinence Associated Dermatitis (CONSIDER) and Outcomes for Pressure Ulcer Trials (OUTPUTs) initiatives.
Sanna Prinsen
Amsterdam,
Netherlands
Dr. Cecilia AC Prinsen is an assistant professor in Clinimetrics at the department of Epidemiology and Biostatistics of Amsterdam UMC, location VUmc, Amsterdam, the Netherlands. She is a clinical epidemiologist by background and the focus of her research is on the standardization of outcome measurement in trials and clinical practice. Sanna has been involved in the development of internationally-accepted methodology on COS development (i.e. COMET Handbook); she has taken the lead in the development of a guideline on how to select outcome measurement instruments for outcomes included in a COS, and in the development of a guideline for systematic reviews of patient-reported outcome measures (PROMs). In addition, she was involved in the development of updated methodology for the evaluation of the quality of measurement instruments (i.e. COSMIN Risk of Bias checklist).
