Abstract

The present invention affords an information system that is simple to use, can be queried in a user-friendly manner, is capable of searching multiple resources in parallel to effect an efficient search, presents diverse information in an easy-to-comprehend format, and allows rapid and intuitive navigation among high-quality contextual information. The invention allows a user to enter a simple query, search all available resources in parallel (or alternatively select only those resources of interest), and navigate among the search results using an intuitive user-interface to develop an action plan based on the resulting information. As a result, a user takes information from several sources and turns that information into action-oriented knowledge that can be applied to solve a particular problem. The amount of information available is secondary to the quality and relevance of the information and how readily it can be synthesized as knowledge by the user. The invention may also afford multiple educational aspects where a user can attain credit for the review and application of the information retrieved and where integration of the system with an electronic medical record provides information on the impact of learning on order entry and clinical outcomes.
