Several Volumes (it’s large)

Vol. 1 – defines the Profiles

IHE Integration ProfileIHE Integration Profile

Integration Profile: The Most Important Term Vendors implement them Users buy them / list them in RFPs

Each Profile defines a Problem / Solution E.g. IHE Scheduled Workflow Profile (SWF) “How do I maintain the integrity of patient demographic & order

information and manage workflow in the Radiology Dept?”

The Profile bundles all the necessary integration for the solution

IHE Integration ProfileIHE Integration Profile

In each Profile in the Tech. Framework: the context is described (Use Cases)

(what real-world problem is addressed) the actors are defined

(what systems are involved) the transactions are defined

(what do they have to do when they talk)

IHE TransactionsIHE TransactionsThe guts of IHE - Vol. 2 of the Technical Framework

This is the product implementation guide

Each Transaction: Addresses a specific exchange of data Selects an existing, open standard (e.g. HL7, DICOM, SMTP, …) Documents how to use the standard to implement the transaction Strictly specified to avoid incompatible implementations (retire

options, clarify data model, etc.)

Re-usable, may appear in multiple Profiles

Defines external interface Does not constrain System internal functions

11IHE Canada Workshop 2006IHE Canada Workshop 2006

IHE TransactionsIHE Transactions

E.g. Query Modality Worklist Transaction [RAD-5]

Details Include: Based on DICOM Modality Worklist Management Service Specifies mapping from HL7 Order to Worklist Procedure Step Refines Matching Key and Return Key requirements

Defines exchange of data between actors Order Filler Actor <-> Acquisition Modality Actor

12IHE Canada Workshop 2006IHE Canada Workshop 2006

IHE ActorIHE Actor

A generalized system function, e.g. : Order Placer Order Filler Audit Repository

Implementers choose which Actors included in system

E.g. Order Filler In the RIS? In a Broker Box? In the PACS? Sure, just implement the transactions assigned in the Profile

Systems may group several Actors e.g. LIS = Order Filler + Lab Automation Manager + Result Tracker

Report Creator Patient Identity Source Document Repository

IHE National ExtensionsIHE National Extensions

Technical Framework is Global

National Extensions are Appendices in TF: Documents national clarifications and extensions Mostly translations and minor variations Additional codes for national practices E.g. Use of a Provincial Insurance Number

Radiology TF - Volume 4 Includes France, Germany, U.S., Italy, U.K. Canadian Extension is near completion
