  1. Berthold Wein,Dept. Diagnostic RadiologyUniversity Hospital Aachen The Clinical Benefits of IHE The first 7 IHE Integration Profiles, for a Better Practice

  2. Selected Problems: (Overview) • Seamless workflow • Data consistency • Image presentation • Spiral CT examinations • Information distribution • Image notification • Parametric access to images and reports

  3. Workflow • Most critical issue in a Radiology Environment • Inter- or corrupted information chain • Paper based informations -> multiple re-entry of data • Different non adapted subsystems don‘t cooperate • Error correction takes huge amount of time • Stale information • Brandnew information not known (cancellation, change) • Status update information • Exam registered, finished, archived, reported, delivered

  4. ADT Patient Registration Patient Registration Scheduled Workflow Admit, order, schedule, acquire images, notify of completed steps Patient Update Image Creator Order Placer Storage Commit Image Display Images Stored Filler Order Management Placer Order Management Q /R Key Image Note Present.

  6. Data Consistency • Trauma patient • Manual wrong data entry at the modality • System crashed • VIP person

  7. Scheduled Workflow Admit, order, schedule, acquire images, notify of completed steps Patient Information Reconciliation Unknown patients and unscheduled orders IHE Integration Profiles

  8. Image presentation • Viewing on different monitors / systems • Ensuring print quality outside of the department • Radiologist discussing images with remote physicians • Capture image manipulation to avoid redundant work (coronal CT, MR reading, etc.)

  11. Re-arranging Series • CT/MR: Head bone / brain separation (external/internal) • CR: Foot/ankle - hand/wrist • E.g., lateral image of foot shared between AP of ankle and AP of foot • DR: Trauma patient AP / Lat re-grouping • I.e., do all the Aps then rotate the patient once then do Lats • MR: MRI/MRA • To be viewed and billed separately • IR: Diagnostic run and therapeutic run • Performed contemporaneously, viewed/billed separately • US: Abdomen and kidneys / retroperitoneum and lymphnodes

  14. Information distribution • Therapy related imaging • Radiation therapy • Computer assisted surgery (orthopaedic, neurosurgery, ...) • Secure image distribution within the enterprise and to the outside world

  20. Parametric access to images and reports Discussion Comparison is made to the prior study of 11.04.1999. The left paratracheal lymph node (image 8, image 11) now measures 2.5x2.7x3.1 cm increasing from 2.0x2.1x2.6 previously. No other mediastinal, upper abdominal or axillary adenopathy is identified. No focal pulmonary lesions are seen. The yadda, yadda, yadda are normal. Impression Worsening left paratracheal adenopathy. Signature

  25. Clinical Benefits by IHE • The power of IHE to improve productivity and reduce errors is really great • Clinical workflow will re-gain resources • Systems connectivity increases • => Daily work will become worthwhile again
