Our mission is to strengthen the focus on the patient perspective in medicine by using patient-reported outcomes measures (PROMs) and by learning about the needs and experiences of people living with a chronic disease.



These are some examples of the questions we want to answer with our research:

What is important to patients?

What are their experiences in the healthcare system?

What do healthcare providers need to successfully use PROMs in daily practice?

What do patients expect from their treatment?

How do patients and clinicians communicate?




We make use of a broad range of scientific methods allowing us to get a comprehensive understanding of the patient perspective.

As research group at the Institute of Health Care Research in Dermatology and Nursing, our research is rooted in the dermatological field. Within the last decade, we have extended our research to further medical areas, including neurology, oncology, and others.

Our key topics are:


  • Health-related quality of life

  • Subjective well-being

  • Patient-defined treatment goals

  • Patient-relevant treatment benefit

  • Subjective symptoms

  • Patient-clinician interaction

  • Patient experiences in the healthcare system

We make use of:


  • Qualitative methods

    • In-depth interviews

    • Focus groups

    • Document analysis

  • Quantitative methods

    • Psychometric evaluation

    • Item-response theory

    • Multivariate analyses

    • Ecological momentary assessment

  • Mixed-methods

Our research is funded by the DFG (German Research Foundation), the BMBF (German Federal Ministry of Education and Research), the EADV (European Academy for Dermatology and Venerology), pharmaceutical industry and others.


In our research projects, we cooperate with a wide range of clinical, research, and industry partners, such as the School of Health and Related Research (ScHARR) at University of Sheffield; the School of Health Sciences, University of Dundee; the Specialized Hospital Bad Bentheim; the Department of Dermatology at the University Hospital Schleswig-Holstein; AstraZeneca; Almirall; Urgo; and many more.
