IHE IT Infrastructure Domain Update Karen Witting – IBM IT Infrastructure Technical Committee co-chair

IT Infrastructure Domain (ITI) Supports profiles which supply necessary infrastructure for sharing healthcare information. IT Infrastructure domain began in 2003 and now has 27 profiles that it supports. Key ITI profiles demonstrated today: – Information Exchange: XDS.b, XDM, XDS-SD, RFD – Security: ATNA, CT, XUA, BPPC – Identity Management: PIX, PDQ (HL7 V2 & V3)

An Infrastructure Interoperability Component Is… An infrastructure Interoperability component… – Represents a common IT function or service that is used as a building block for a variety of use cases – May be imbedded in an application, but is often deployed as a shared resource within a RHIO or Health Information Exchange – Is a necessary ingredient, but is rarely visible to the end user

Categories of Healthcare Communication Services Security/Privacy Document Sharing Patient and Provider Identity Management Dynamic Information Access Workflow Management Source persisted and attested health records Specific info snapshot provided on demand 2 or more entities synchronize a task e.g. access last 6 mo. historical labs & encounter summaries e.g. order lab test, track status and receive results e.g. get current list of allergies or med list from source Hospitals HIEs and RHIOs
