Regina Kunz has recently been appointed Director of the Institute for Insurance Medicine at the University and University Hospital Basel, Switzerland. Nephrologist and clinical epidemiologist by training, she has comprehensive expertise in doing systematic reviews, meta-analyses and health technology assessments. Then, her clinical practice reminded her day by day how important it is to have high quality syntheses at hand when advising patients and making management decisions. Today, the lack of high quality evidence synthesis in insurance medicine is a painful experience that urgently needs change. Her academic activities within the Grading of Recommendations Assessment, Development and Evaluation (GRADE) working group on guideline methodology and as a long-standing board member of the Guidelines International Network G-I-N corroborate the need for high quality reviews and meta-analyses in all areas of healthcare, to provide physicians, patients and decision makers with sound recommendations, and the difficulties of delivering convincing recommendations in the absence of such reviews. She is the founding member of the German Network EbM, editor of the German textbook Evidence-based Medicine in Clinic and Practice, and has a great deal of experience in running teaching courses on systematic reviews and meta-analyses, the GRADE-methodology and evidence-based medicine worldwide.
