Outline

Outline

  • Background

  • Summarize the activities by IHE-J in digestive endoscopy scene

    • Characteristics of workflow of endoscopy

  • Discussion

IHE Endoscopy with DICOM WG13


What is an endoscopy

What is an “Endoscopy”

Endoscope

Main targets:

Digestive tracts

Bronchial tubes…

Variety of “Endoscope”

Laparoscope

Capsule endoscope…

Biopsy Forceps

IHE Endoscopy with DICOM WG13


Standardization in digestive endoscopy scene

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

IHE Endoscopy with DICOM WG13


Activities of ihe j endoscopy wg

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)

Discussion

Discussion

  • IHE-J decided that the radiology SWF could not satisfy endoscopists’ demand.

  • IHE-J established “Endoscopy SWF”.

IHE Endoscopy with DICOM WG13


What is a workflow fitting endoscopy scene

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”.

  • IHE Endoscopy with DICOM WG13


    An ideal data structure for endoscopists

    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

    Discussion for pathology order from endoscopy reporting system we met an obstacle

    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).

    Current state of japan ihe activity

    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

    IHE Endoscopy with DICOM WG13


    Our scope

    Our scope

    • To establish another “Endoscopy” profiles

      • Bronchoscopy

      • Laparoscopy

      • Capsule endoscopy…

    • Think about basic of DICOM protocol

      • MWM, MPPS are comfortable for endoscopy?
