My Personal Information Needs

Addressing Information Needs with Infobuttons Clinical information systems evoke information needs Clinician’s computer has access to resources Context can be used to predict need Context can be used to automate retrieval

Infobuttons Anticipate Need and Provide Queries i

First Attempt: The Medline Button CIS on mainframe BRS/Colleague (Medline) on same mainframe Get them to talk to each other Search using diagnoses and procedures

First Attempt: The Medline Button CIS on mainframe BRS/Colleague (Medline) on same mainframe Get them to talk to each other Search using diagnoses and procedures Technical success Practical failure

Infobuttons Web-based More resources Hardwired links in clinical system Customize search with concept of interest

Institution-Specific Requirements What are the users’ information needs? In what contexts do those needs arise? What resources will resolve the needs? Terminology? How can the Infobutton Manager be integrated into the clinical information system?

Institution Customization Institution librarians know their clients best Institution librarians know their resources How can librarians populate Infobutton Manager tables? Terminology is institution-specific How do we handle institution-specific data translation?

LITE Research Plan Conduct community assessment Refine LITE features Establish forum for feedback from librarians Develop LITE in an iterative manner Develop a user manual and tutorial Evaluate usability of LITE by librarians Evaluate the use of LITE Disseminate the results of the project Promote the use of the IM and LITE

Conclusions Infobuttons can anticipate and resolve clinicians’ information needs Institution-specific tailoring is required LITE will make Infobutton Manager accessible HL7 standard will simplify links from commercial clinical systems HL7 link to knowledge resources is feasible
