Retrieve Information for Display enables simple and rapid access to patient information for better care.  It supports access to existing persistent documents in well-known presentation formats such as CDA, PDF, JPEG, etc.  It also supports access to specific key patient-centric information such as allergies, current medications, summary of reports, etc. for presentation to a clinician.  It complements workflows from within the users on-screen workspace or application. By linking it with two other IHE profiles - Enterprise User Authentication and Patient Identifier Cross-referencing for MPI, this profile s reach can extend across organization boundaries.  This IHE Integration Profile leverages HTTP, Web Services, IT presentation formats and HL7 CDA.
