Abstract: Modern medical libraries have an important responsibility to provide updated, reliable knowledge services for evidence-based medicine. In recent years, a series of websites, such as Clinical Evidence, DynaMed, Essential Evidence Plus, MD Consult, and UpToDate, were established to provide synthesized knowledge services for clinical physicians based on massive data resources in medical libraries. Physicians and patients can use these systems to find relevant knowledge services according to their needs and interest. Evidence-based medical knowledge service platforms have received wide welcome from the international medical professionals, and have become an indispensable tool for clinical decision-making. This article introduced several famous knowledge service platforms, analyzed their functions and technical characteristics, and discussed their role in clinical decision-making.
