[Evidence-based surgery - The Study Center of the German Surgical Society]. / Generierung von Evidenz in der Chirurgie - Das Studienzentrum der Deutschen Gesellschaft für Chirurgie.

The Study Center of the German Surgical Society (SDGC) assists surgeons to develop research questions and conduct clinical trials. Development (sample size calculation, protocol, funding application), implementation (submission to ethics committee, data management, monitoring) and analysis (statistical analysis, publication) are supported by SDGC specialists such as biometricians and project managers. Currently approximately 4,800 patients have been included in 15 trials. Systematic reviews with meta-analyses are the basis of valid sample size calculation by aggregating the results of existing studies systematically. In 2005, a work group for the development of systematic reviews has been established at the SDGC. Sixteen publications have so far been completed, and eight more are underway. Using clinical trials and systematic reviews as the fundamental cornerstones in evidence-based medicine, the SDGC has developed an effective network for clinical research in surgery.
