title: Center for clinical studies in a surgical department--an approach for more evidence-based medicine.
abstract: The concept of evidence-based medicine (EBM) has been introduced into the field of surgery in Germany since 1996, initially focussing on the application of the classical five-step-concept of EBM to the individual patient. Despite the international efforts of the Cochrane Collaboration, few systematic reviews address surgical procedures and the number of high quality randomized-controlled trials (RCTs) are low. External evidence in surgery is a major problem and requires new strategies in research and patient care. Therefore, in the Department of Surgery at the University of Heidelberg a clinical trial unit was founded to create more evidence via two approaches. First, patients admitted to hospital should be treated within RCTs. Since May 2002 1808 patients have been enrolled into a total of 38 pharmaceutical (19 trials with 470 patients enrolled) and investigator initiated (19 trials with 1338 patients enrolled) studies. Second, the clinical site develops and conducts surgical efficacy RCTs and follows new standards including publication and registration of the protocols. Within 3 years it was possible to change practice in an academic setting from the traditional concept to an evidence-based approach.
