DynaMed is a clinical reference tool created by physicians for physicians and other health care professionals for use primarily at the 'point-of-care'. With clinically-organized summaries for more than 3,000 topics, DynaMed is the only evidence-based reference shown to answer most clinical questions during practice. Based on the results of a study published in Annals of Family Medicine (November/December 2005), not only did primary care clinicians answer more clinical questions with access to DynaMed than without DynaMed, but these clinicians also found more answers in DynaMed that changed clinical decisions.

DynaMed is updated daily and monitors the content of over 500 medical journals and systematic evidence review databases directly and indirectly by using many journal review services. Each publication is reviewed cover-to-cover, and each article is evaluated for clinical relevance and scientific validity. The new evidence is then integrated with existing content, and overall conclusions are changed as appropriate representing a synthesis of the best available evidence. Through this process of systematic literature surveillance, the best available evidence determines the content of DynaMed.
