Integration Profiles - Overview Integrating the Healthcare Enterprise G. Claeys Agfa Healthcare R&D, Technology Manager Vendor co-chair IHE Europe Courtesy of IHE Committees

7 February 2005IHE Europe Educational Event 2 Integration Profiles - Objective Address real-world interoperability problems (bottom-up approach) Leverage same integration solutions over multiple domains (top-down)  Generalized solutions  Example : Scheduling exams, display `exam results Integration Profiles are orthogonal  IPs are independent of each other  Applications may combine multiple Integration Profiles E.g. Information access + security

7 February 2005IHE Europe Educational Event 5 IHE Scope

7 February 2005IHE Europe Educational Event 6 IHE Radiology – Focus Points Streamline the workflow sub-processes  Upstream : Patient ADT – Ordering – Data creation & processing  Downstream : Reporting – Treatment – Billing  Exception management : e.g. update unknown patient IDs Quality control  Consistent presentation of images on displays & printers Improve communication with referring physicians  Access to information, generated in radiology (images, reports)  Image notes (post-its) Improve machine-machine communication (automatic processing)  Structured reports  Measurements and coded data Security :  Adhere to (parts of) existing Security&Privacy regulation  authentication, auditing Off-line medium distribution (new)

7 February 2005IHE Europe Educational Event 7 Patient Information Reconciliation Reconcile Worklists, Status and Data Objects For Unknown Patients and Demographics Changes Access to Radiology Information Consistent Presentation of Images Create, store, manage, retrieve & use objects for hardcopy and softcopy grayscale presentation states Key Image Notes Create, store, manage, retrieve & use objects to flag significant images Simple Image and Numericc Reports Create, store, manage, retrieve & use simple diagnostic reports with optional image links & Scheduled Workflow Presentation of Grouped Procedures Manage individual procedure image subsets from a multi-procedure acquisition for viewing & reporting Basic Security Charge Posting Reporting Workflow Manage worklists, track status, perform & notify diagnostic reporting steps Evidence Documents Create, store, manage, retrieve & use objects to record study evidence Manage worklists, track status, perform & notify image processing & CAD steps Post - Processing Workflow Create, Store, Manage, Retrieve & Use Images Admission, Order Management, Scheduling, Store, Retrieve Manage Worklists, Track Status, Perform & Notify Acquisition Related Steps Radiology – Integration Profiles New NM Image Portable Data for Imaging New

7 February 2005IHE Europe Educational Event 8 IHE IT Infrastructure – Focus Points Enterprise interoperability issues, common to multiple departments Improve information consistency among applications & departments :  Cross referencing patient IDs among hospitals (MPI)  Patient synchronisation of multiple desktop applications Simple access to patient’s clinical information from workstations and browsers  Reports, images, Simple access to administrative information of patient and staff  Patient’s demographic information, personnel directory Security :  Single sign-on (shared user context)  Centralized user management  Audit trails on enterprise level Sharing of clinical information among healthcare providers (e.g. regional health networks)

7 February 2005IHE Europe Educational Event 9 IT Infrastructure – Integration Profiles Enterprise User Authentication Provide users a single name and centralized authentication process across all systems Retrieve Information for Display Access a patient’s clinical information and documents in a format ready to be presented to the requesting user Retrieve Information for Display Access a patient’s clinical information and documents in a format ready to be presented to the requesting user Patient Identifier Cross-referencing for MPI Map patient identifiers across independent identification domains Patient Identifier Cross-referencing for MPI Map patient identifiers across independent identification domains Synchronize multiple applications on a desktop to the same patient Patient Synchronized Applications Consistent Time Coordinate time across networked systems Audit Trail & Node Authentication Centralized privacy audit trail and node to node authentication to create a secured domain. New Patient Demographics Query New Personnel White Page Access to workforce contact information New Cross-Enterprise Document Sharing Registration, distribution and access across health enterprises of clinical documents forming a patient electronic health record New

7 February 2005IHE Europe Educational Event 10 IHE Laboratory – Focus Points Leverage schedule workflow of radiology  Ordering, scheduling and performing clinical laboratory tests Support specimen testing on the point of care or on the patient’s bedside  Delivering the observation results to the medical staff, at various steps of validation. Manage the sequence of operations of automated lab equipment  E.g. analyzers, robotic decappers, centrifuges, conveyors All specialties working on specimen, not on the patient itself.

7 February 2005IHE Europe Educational Event 12 IHE Cardiology – Focus Points Leverage “schedule workflow” (radiology) for cath lab and echocardiography Leverage “retrieve for display” for ECG’s Differences with radiology :  Echo cardio modalities are not always on-line  Ad-hoc scheduling is the rule, not the exception  Time synchronization among multiple modalities

7 February 2005IHE Europe Educational Event 13 IHE Cardiology – Integration Profiles Cardiac Catheterization Workflow New Echocardiography Workflow New Retrieve ECG for Display Integration Profile (RED) Provide ECGs and related documents to enterprise New
