Common and distinct needs in CardiologyCommon and distinct needs in Cardiology Data Complexity and WorkflowData Complexity and Workflow Applying Scheduled Workflow in CardiologyApplying Scheduled Workflow in Cardiology Challenges and next steps…Challenges and next steps…

3 HIMSS What is IHE about? Its an initiative promoting and supporting the integration of systems in the healthcare enterprise.Its an initiative promoting and supporting the integration of systems in the healthcare enterprise. Integration Goal: Improve the efficiency and effectiveness of clinical practice by:Integration Goal: Improve the efficiency and effectiveness of clinical practice by: –Improved Information Flow –Advanced Multi-System Functions

4 HIMSS Why is IHE needed? Serious Integration Challenges in Healthcare:Serious Integration Challenges in Healthcare: Systems need Information other systems haveSystems need Information other systems have But, systems communicate poorly or not at allBut, systems communicate poorly or not at all Result: - tedious, inefficient workflows - data that is inconsistent or unavailableResult: - tedious, inefficient workflows - data that is inconsistent or unavailable Responsibility for information flow between systems, and between departments, is often unclear.

5 HIMSS Who is IHE? Participants:Participants: –Professional Societies (RSNA/HIMSS/…) –Vendors (over 30 companies) –Standards Group Committee Members RSNA and HIMSS sponsor IHE to provide a neutral forum for working on the Big PictureRSNA and HIMSS sponsor IHE to provide a neutral forum for working on the Big Picture

6 HIMSS What Does IHE Do? Users and vendors work together to identify and design solutions for integration problemsUsers and vendors work together to identify and design solutions for integration problems Intensive process with annual cycles: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 tradeshows (RSNA/HIMSS)

7 HIMSS Arent DICOM / HL7 Sufficient? Standards are vital (HL7, DICOM, ICD, …)Standards are vital (HL7, DICOM, ICD, …) –They provide tools & technologies But Standards alone are insufficientBut Standards alone are insufficient –They are open to interpretation –There is room for optional variations –They avoid specifying how to apply them to particular real world scenarios

8 HIMSS How is IHE related to Standards? IHE attacks real world integration problemsIHE attacks real world integration problems HL7 and DICOM provide dictionariesHL7 and DICOM provide dictionaries IHE defines a phrasebook that solves real world problems by assembling pieces provided by DICOM/HL7IHE defines a phrasebook that solves real world problems by assembling pieces provided by DICOM/HL7

9 HIMSS What are Key IHE Concepts? Generalized Systems -> ActorsGeneralized Systems -> Actors Interactions between Actors -> TransactionsInteractions between Actors -> Transactions Problem/Solution Scenarios-> Integration ProfilesProblem/Solution Scenarios-> Integration Profiles For each Integration Profile:For each Integration Profile: the context is described (which real-world problem)the context is described (which real-world problem) the actors are defined (what systems are involved)the actors are defined (what systems are involved) the transactions are defined (what must they do)the transactions are defined (what must they do)

13 HIMSS Why IHE in Cardiology? Cardiology workflow is complexCardiology workflow is complex Multiple diagnostic tests are very commonMultiple diagnostic tests are very common –Large number of manual demographic input steps is common. –This leads to inefficiency, invalid data in clinical archives and can lower the quality of care

14 HIMSS Why IHE in Cardiology (2) ? The Cardiology position in the IT technology adoption cycle makes the IHE an ideal foundationThe Cardiology position in the IT technology adoption cycle makes the IHE an ideal foundation The concepts of the IHE TF have broad general applicability, many can be directly leveraged in CardiologyThe concepts of the IHE TF have broad general applicability, many can be directly leveraged in Cardiology Some of Cardiologys special requirements can be well met by the IHE TFSome of Cardiologys special requirements can be well met by the IHE TF The TF could be adapted to meet Cardiology specific needsThe TF could be adapted to meet Cardiology specific needs

15 HIMSS Common Needs Cardiology departments have needs similar to Radiology departmentsCardiology departments have needs similar to Radiology departments –Both are driven by imaging modalities –Workflow is similar at a very high level –Need to manage distributed departmental resources –Desire an integrated patient-centered view –Need for administrative reporting –Need to improve lab efficiency via workflow management

16 HIMSS Distinct Cardiology Needs Clinical data content is more complexClinical data content is more complex –Procedural data with rich report content Direct tie to billingDirect tie to billing –Clinical results data mining is a priority Cardio departments are often more driven/isolated by subspecialtyCardio departments are often more driven/isolated by subspecialty Legacy installed base without clear connectivity path is largeLegacy installed base without clear connectivity path is large Strong individual patient focus than a system or procedure focusStrong individual patient focus than a system or procedure focus Cardio departments are revenue centersCardio departments are revenue centers

17 HIMSS Complexity of Core Data RadiologyRadiology –Diagnostic Imaging CT,MR,US,NM…CT,MR,US,NM… Scanned FilmScanned Film –Text Reports –Measurements Cardiology –Diagnostic Imaging XA, US, NM, CT, MR –Waveforms ECG, Hemo, EP, Stress –Extensive numeric measurements –Lab data –Complex Reports Stress,Holter, Cath

18 HIMSS Cardiology Workflow Elements Workflow elements in common with Radiology:Workflow elements in common with Radiology: –Patients are admitted –Demographics entered (often multiple times for the same patient) –Imaging studies are performed and read –Reports generated

19 HIMSS Cardiology Workflow Elements Additional Workflow elements:Additional Workflow elements: –Echo, ECG & lab data often prerequisites to treatment –Consumable materials and clinical data tied to procedures –Monitoring data is part of the Cath procedure –Echo as follow on to a Cath procedure –Interpretation generally uses multiple clinical inputs

20 HIMSS Scheduled Workflow Works for Cardiology Minimizing redundant demographic input and producing valid header data in the clinical archive is important in CardiologyMinimizing redundant demographic input and producing valid header data in the clinical archive is important in Cardiology –Multiple modality inputs of Cardiology drives the value –Basic problem is well addressed by the Scheduled Workflow and Patient Reconciliation Integration Profiles in IHE Year 3

21 HIMSS Patient Information Reconciliation Profile Works for Cardiology Extends Scheduled WorkflowExtends Scheduled Workflow –Handle unidentified patient (e.g. emergent) –Handle demographic information mistakes –Propagate changes to all affected systems, update all affected data Reduces incorrectly identified or lost studiesReduces incorrectly identified or lost studies Can reduce lost charge postings (billing)Can reduce lost charge postings (billing)

22 HIMSS Can you Just Do It? We have done some investigations and prototype clinical testing to examine the utility of applying the concepts of Scheduled Workflow and Patient ReconciliationWe have done some investigations and prototype clinical testing to examine the utility of applying the concepts of Scheduled Workflow and Patient Reconciliation Key PiecesKey Pieces –HIS, RIS, Modality & PACS The HIS is the sameThe HIS is the same So far this is easy…So far this is easy…
