Institut für Medizinische Statistik - UMG

Systematic Review Unit


Die Zahl wissenschaftlicher Veröffentlichungen nimmt jedes Jahr stark zu. Dies stellt für Ärzte und Wissenschaftler, die sich über ein medizinisches Themengebiet umfassend und aktuell informieren möchten, eine große Herausforderung dar. Daher ist es notwendig, einzelne Studien zur gleichen Thematik systematisch zu erfassen, kritisch zu bewerten und, wenn möglich, zusammenzufassen. Solche Informationssynthese kann in Form von systematischen Übersichtsarbeiten und Meta-Analysen geschehen. Die Institute Allgemeinmedizin, Medizinische Statistik und Arbeits- und Sozial- und Umweltmedizin besitzen in diesem Bereich Kernkompetenzen und praktische Erfahrungen.

Zielgruppe und Ziele

Mitglieder der Systematic Review Unit

Die Systematic Review Unit wurde im Jahre 2010 von Prof. Jean-Francois Chenot (Allgemeinmedizin), PD Dr. Sebastian Straube (Arbeits-, Sozial- und Umweltmedizin) und Prof. Tim Friede (Medizinische Statistik) gegründet. Sebastian Straube ist Mitglied der Editorial Boards der Pain, Palliative and Supportive Care Group der Cochrane Collaboration sowie der Zeitschriften ISRN Pain und ISRN Obesity. Sebastian Straube ist außerdem im Komitee der Special Interest Group on Systematic Reviews in Pain Relief der International Association for the Study of Pain. Tim Friede ist Reviewer in der Multiplen Sklerose Gruppe der Cochrane Collaboration.
