2 September, 2005What IHE Delivers VA Success Story – Image Acquisition using IHE Scheduled Workflow June 6~7, 2006 Peter Kuzmak, Andrew Casertano, and Dr. Ruth Dayhoff Department of Veterans Affairs

3 2 VA Healthcare Enterprise 157 Medical Centers & 850+ Outpatient Clinics Serves an active patient population of 5 million veterans All sites acquire DICOM images ½ billion images online ½ million images acquired each day

4 3 VistA & Computerized Patient Record System

5 4 Multimedia Patient Record Chart Data Textual chart data Computable data Handwritten and non-electronic chart data Multimedia Data Images, graphics, waveforms, audio, etc. Computerized Patient Record and VistA Imaging

6 5 Wide Variety of Images Integrated with the Online Patient Record Cardiology Bronchoscopy Gastrointestinal Endoscopy Hematology Pathology Surgery Nuclear Medicine Dental Radiology Dermatology Ophthalmology Podiatry Vascular Urology Nursing Electrocardiography Scanned Documents

7 6 VA IHE Success Story All VA DICOM image acquisition uses IHE Radiology Transactions to interface modalities to PACS: #5 - Modality Worklist Provided - download patient and study #8 - Modality Images Stored - send images to the PACS. One interface for 250 different models of instruments! Radiology, ophthalmology, dentistry, endoscopy, pathology, and cardiology. VA/DoD DICOM Modality requirements documents: The VA will not purchase a new modality unless it supports these capabilities.

8 7 Using Consults for Clinical Specialties (Simplified Workflow) 1. Consult Ordered 2. Schedule Appointment 3. Patient Arrives 4. Images Acquired 5. Patient Leaves 6. Diagnostic Reporting 7. Follow up Visits

9 8 VA Hospital Information System P A C S Acquisition Modality Worklist Query Worklist Response Workflow Transactions

10 9 VA Hospital Information System P A C S Acquisition Modality Worklist Query Worklist Response Storage Workflow Transactions Image Retrieval

11 10 VAs Role in Advancement of DICOM in Ophthalmology Initially no Ophthalmology specification in DICOM Could not even tell left from right VA encouraged AAO develop new specification Ophthalmic Photography Image DICOM Supplement – Organized the IHE Eye Care Showcase 2006 – VA national Diabetic Retinopathy Surveillance program Fundus Image 3072 x bit

15 14 IHE Value to Vendors IHE Technical Framework defines implementation specifications in detail Resources needed to developed, test, and maintain just a single interface IHE provides interface testing tools and vendor-to- vendor interoperability Connectathon. IHE saves vendors money

16 15 Conclusion: Follow IHE for Success IHE enables interoperability and saves money Using industry standards avoids having to develop custom interface methodologies Provides smoother integration Accelerates acceptance testing Cost-effective for all participants
