Infobuttons are clinical decision support tools that use information about the clinical context (institution, user, patient) in which an information need arises to provide direct access to relevant information from knowledge resources. Two freely available resources make infobutton implementation possible for virtually any EHR system. OpenInfobutton is an HL7-compliant system that accepts context parameters from an EHR and, using its knowledge base of resources and information needs, generates a set of links that direct the user to relevant information. The Librarian Infobutton Tailoring Environment (LITE) is a second system that allows institutional librarians to specify which resources should be selected in a given context by OpenInfobutton. This paper describes the steps needed to use LITE to customize OpenInfobutton and to integrate OpenInfobutton into an EHR.
