1 IHE Endoscopy with DICOM WG13 “IHE-J Endoscopy” The concept of Japanese activities Hideto Yokoi (IHE-Japan Endoscopy Working Group)

2 IHE Endoscopy with DICOM WG13 Outline Background Summarize the activities by IHE-J in digestive endoscopy scene  Characteristics of workflow of endoscopy Discussion

3 IHE Endoscopy with DICOM WG13 What is an “Endoscopy” Endoscope Biopsy Forceps Main targets: Digestive tracts Bronchial tubes… Variety of “Endoscope” Laparoscope Capsule endoscope…

4 IHE Endoscopy with DICOM WG13 Standardization in digestive endoscopy scene Standardization of contents  Data models MST Standardization of communication.  Protocols for communication between systems HL7 (using commonly in US endoscopy scene) DICOM (discuss in WG13, contents(tag), movie format… ) IHE Endoscopy has a international terminology. OMED (World Organisation of Digestive Endoscopy) supporting IHE-J endoscopy WG

5 IHE Endoscopy with DICOM WG13 Activities of IHE-J Endoscopy WG Technical Framework I Japanese version completed, Public comments invited: April 2006 The English version created: September 2006 TF II is now being created (by JAHIS) Preparation for implementation is being conducted in Kagawa University Hospital  By Olympus, Fujitsu, JR west, DGS computer, Seafic software Mutual connection with DICOM WG13 (Visible Light) Informal meeting in RSNA 2006: November 29 Plan: Connectathon in 2007, Year 2 document (discussion of new scenarios such as colonoscopy and laparoscopy)

10 IHE Endoscopy with DICOM WG13 Discussion IHE-J decided that the radiology SWF could not satisfy endoscopists’ demand. IHE-J established “Endoscopy SWF”.

13 IHE Endoscopy with DICOM WG13 What is a workflow fitting endoscopy scene? The workflow needs an interaction with pathology department system. Decided to have transactions for the linkage information between Endoscopy order/report and Pathology order/report. The interaction needs endoscopy report describing where & how specimens were gotten. Included “Reporting workflow” in the “Endoscopy SWF”.

14 IHE Endoscopy with DICOM WG13 An ideal data structure for endoscopists How do we handle a primary exam and secondary exam? Endoscopy record  finding Pathology report (Procedure record) Analytic report from Lab (biochemical test, germ culture etc.) (Procedure record)  (Procedure record) “Procedure record”  Financial data for insurance  Used material or/and device for logistics

15 IHE Endoscopy with DICOM WG13 GUI image that we want DateEvent Endoscopy (EGD) Pathology (biopsy from stomach) Germ culture Report of endoscopy There is “Ulcer” in the stomach. stage: A1 Bleeding: (+) … biopsy:1. from the side of ulcer :2. oral side of Endoscopy Image 1. Group 1: ulcer 2.Group 3: anomaly of some cells… Pathology results Window of EMR

16 IHE Endoscopy with DICOM WG13 Discussion for “Pathology Order” from endoscopy reporting system. [We met an obstacle.] The issue is discussed in Message Exchange Standard Committee in JAHIS  Many Japanese HIS are integrated by CPOE (computer physician order entry) system.  The CPOE is working as a “hub” integrating some department systems in Japanese hospitals.  Basically, CPOE does not accept the orders from department systems (only from physician’s console acceptable).

19 IHE Endoscopy with DICOM WG13 Current state of Japan’ IHE activity The “Japan IHE Association” established in April 2007 The sponsor is shifting from Ministry of Economy, Trade and Industry (METI) to Ministry of Health, Labour and Welfare (MHLW)  The change is hoped to lead the rapid spread of IHE in Japanese medical scene

20 IHE Endoscopy with DICOM WG13 Our scope To establish another “Endoscopy” profiles  Bronchoscopy  Laparoscopy  Capsule endoscopy… Think about basic of DICOM protocol  MWM, MPPS are comfortable for endoscopy?
