IHE Cardiology – Discussion with EP Subcommittee Harry Solomon, co-chair IHE Cardiology Tech Cttee 12 August 2005
Why IHE? • Cardiology has hardsystem and data integration problems • Multiple locations (office, in-patient, ED …) • Multiple devices and modalities • Long term patient care by many care providers • Data integration is essential to quality patient care • Care providers must work with industry to develop solutions to meet their needs • Implementations must be based on open standards
What is IHE? • An initiative to improve systems integration and interoperability for a multi-vendor Enterprise • A process for coordinated adoption of standards • Clinicians define their highest priority integration problems • Vendor committees develop solutions and produce a Technical Framework • Industry adopts and implements solutions in products • Professional Society sponsors supervise documentation, testing, demonstration and promotion
Goals of IHE • Accelerate standards-based healthcare data integration • Improve clinical and administrative workflow • Improve data flow – where it’s needed, when it’s needed • Improve the efficiency and effectiveness of clinical practice • Advance the healthcare IT market
Who is IHE? • IHE is a joint initiative of: • American College of Cardiology (ACC) • Radiological Society of North America (RSNA) • Healthcare Information and Management Systems Society (HIMSS) • Vendors/manufacturers in major supporting role • Local sponsorship internationally • IHE-Europe and IHE-Asia/Oceania • IHE-Cardiology additional participating societies • ASE, ASNC, HRS, SCAI and more • IHE-Cardiology in Europe sponsored by European Society of Cardiology (ESC)
What IHE is NOT! SDO • NOT a standards development organization • Profiles use of established standards (HL7, DICOM, IETF, others) to address specific clinical needs • Standards promotion organization - complementary to SDOs • NOT a product certification organization • Interoperability testing supervised by Professional societies with vendor-independent test tools • Vendor self-certification based on test results • NOT simply a demonstration project • Demos only one means to the end: adoption
IHE and Standards • Standards are necessary… • but not sufficient – Why ? • Multiple standards and domains - overlap and redundancy • Conflict because domain boundaries are unclear and information models are different • Standards are broad, abstract and flexible • Room for interpretation in implementation hinders interoperability • Standards deal with getting data from A to B… but do not define full end-to-end user workflow across points A, B, C & D • Different techniques for standards development vs. deployment
The IHE Value Proposition • Users get a comprehensive, end-to-end workflow • Uniting multiple systems and multiple standards • Improving cost-effectiveness and quality of patient care • Products can rely on other vendors’ products providing critical information in a consistent manner • Reducing development, validation, and integration costs • Avoiding chicken-and-egg adoption problem • Integration occurs proactively in controlled environment with defined timetable, not reactively at customer site • Common approach creates the market in which vendors can sell and users can buy with confidence • “We each succeed when we all succeed”
IHE Process • Users and vendors work together to identify and design solutions for integration problems • Intensive process with annual cycles: • Identify key healthcare workflows and integration problems • Research & select standards to specify a solution • Write, review and publish IHE Technical Framework • Perform cross-testing at “Connectathon” • Demonstrations at trade shows • Yearly cycle focuses on most important tractable problems

Key IHE Concepts • Generalized Systems -> Actors • Interactions between Actors -> Transactions • Problem/Solution Scenarios -> Integration Profiles • For each Integration Profile: • the context is described (which real-world problem) • the actors are defined (what systems are involved) • the transactions are defined (what must they do)
IHE Technical Frameworks • Detailed standards implementation guides • Cardiology • IT Infrastructure • Lab • Radiology • Patient Care Coordination
Connectathon • Weeklong interoperability testing event • Validation of the participants’ integration work • Prerequisite testing with MESA tools • Test all transactions under all profiles • 100s products, 1000s connections, 10000s messages • Primary IHE benefit for vendors • Test against all other players in one week, in one location (not at customer installation sites!)
Demonstrations • Part of the IHE marketing effort to end-users and system purchasing decision makers • Involve educational sessions, handouts, and interoperating systems demos • Structured to be fair to all participating vendors • Prerequisite is successful completion of Connectathon
IHE Cardiology – where we have been • Year 1 – three profiles with “success path”, addressing broad range of integration problems • Workflow management in a Cath Lab, including angio, hemo, and IVUS, especially for emergent cases • Workflow management in Echocardiography, including mobile echo • Ability to view an ECG from many locations - quickly and easily integrated into other applications • Broad participation in North America and Europe Connectathons and demos
Cath Lab Multiple re-entry of Patient ID Error prone Results fragmented across systems Results inconsistently time-tagged Custom solutions needed for data sharing Difficult to manage Uncoordinated with Hospital Information System Un-ordered cath exams (emergency) Unidentified patients Diagnostic and interventional procedures Ad hoc scheduling of cath labs Change of rooms during procedure 7 6 5 8 10 9 11 4 3 2 1
Echo Workflow • The “drive-by echo” - Cardiologist to sonographer in CCU: “While you’re here, do a TTE on bed 3” • Unordered, unscheduled exam • Modality not on network • Stress echo –After exam, sonographer creates new quad displays of stages and views • No intrinsic value add • Data is redundantly copied to storage
IHE Cardiology – where we are now • Year 2 – enhance profiles to address measurement gathering, and production of final reports • Evidence Document options in Cath and Echo, including procedure log, QCA/QVA, hemo, IVUS measurements • PDF-based Displayable Reports production, archive, and distribution • Demonstration of Cross-Enterprise DocumentSharing between inpatient and ambulatory settings (RHIO)
Evidence Documents Echocardiography Measurement Patient: Doe, John Technologist: der Payd, N Measurements: Mitral valve diameter 3.1cm - shown in image at [ ] Ventricular length, diastolic 5.97 cm - shown in image at [ ] Ventricular volume, diastolic 14.1 ml - inferred from [ ] - inferred from VLZ algorithm • Pick your kludge: • Measurements made on modality or workstation, and written onto a paper worksheet, then transcribed into a report • Measurements output to a printer port, intercepted by an application that scrapes the values • Screen capture of measurements sent to a reporting system, which uses OCR (optical character recognition) to reconstruct the original measurement names and numbers
Cross-enterprise document sharing problem Long Term Care Acute Care (Inpatient) Other Specialized Care(incl. Diagnostics Services) GPs and Clinics (Ambulatory) Typically, a patient goes through a sequence of encounters in different Care Settings
