[Why Switzerland needs evidence-based guidelines for its general practice medicine].

Introduction: Medical guidelines summarize evidence based knowledge and give helpful recommendations for diagnostics and therapy in daily practice. Most Swiss medical societies therefore adapt international guidelines for the Swiss setting. In primary care this adaption must not only take into account the specific Swiss healthcare system, but also the specific setting of primary care, which is characterized by a low prevalence of most diseases as well as by chronic conditions and multimorbidity. Exactly these multimorbid patients are underrepresented in the studies, which underline the current guidelines of medical societies. The institute of primary care at the university of Zurich, IHAMZ, therefore creates evidence based guidelines according to international established quality criteria for the Swiss primary care setting.
