4 RSNA for Administrators Classroom Sessions … a new generation of Healthcare IT solutions that have an order of magnitude greater level of integration. … a whole new level of Complexity Management to manage these interfaces. … we need to Decrease the time for integrating the Multi Vendors systems. … we need the capabilities for plug and play interoperability of systems. … we need to lower the total cost of integration To achieve these goals we need …

5 RSNA for Administrators Classroom Sessions Standards Exists: DICOM, HL7 The main purpose of standards is to lower the cost of integration between systems. The more plug and play integration the lower is the cost of the implementation. However Standards are broad and include options that reduce the interoperability So we need to constrain the Standards in order to improve the interoperability

6 RSNA for Administrators Classroom Sessions What is IHE Joint Initiative from HIMSS and RSNA since 1998 IHE is a specification of transactions between systems that defines integration profiles solution (SWF, PIR, RWF) based on standards Uses a combination of standards to achieve a fully Interoperable workflow Reinforces constrained standards to achieve fully Interoperability

16 RSNA for Administrators Classroom Sessions IHE Deployment – Testing the Integrated System Solutions For Healthcare to succeed in the digital transformation it will need much better integration between its systems. IHE is an open standards approach to lower the cost of integrating healthcare and exposing many more processes. Open Source can accelerate the adoption of IHE by helping to educate administrators to learn how to test the integration

17 RSNA for Administrators Classroom Sessions Open Source - Integration testing tools There are many (dozens) of DICOM and HL7 tools. Too many to mention. The web site openrad.com has a repository with all the main open source Integration testing tools

19 RSNA for Administrators Classroom Sessions Todays Lesson Build an IHE Testing Environment Test IHE Scheduled Workflow Components On a windows laptop

20 RSNA for Administrators Classroom Sessions Standard Documentation Recommendation IHE Technical Framework: volumes #1, 2, 3 –Scheduled Workflow DICOM standard –Information Object Definition Pt.3 –Services Pt.4 –Data Dictionary Pt.6 –Medical.nema.org HL7 v2.3.1 standard

21 RSNA for Administrators Classroom Sessions IHE Medical Enterprise Simulators and Analyzers (MESA) Provides the Test Procedures and Simulation of all the IHE Profiles and Actors. Excellent Documentation. Developed by the Mallinckrodt Institute of Radiology MESA Tools runs on different operating systems: Windows 2000, Windows XP, Solaris 7.0, Red Hat Linux 7.0 & 9.0 from Intel. The MESA tool is organized for particular IHE actors as defined in the IHE Technical Framework

22 RSNA for Administrators Classroom Sessions Step 1. Install MESA tools Decide What Actors/Systems you need to test Read the Installation Guide for installing the tools you need to test your Actors/Systems Precompiled and Source Codes are available Recommend to Install the preferred Windows 2000 precompiled MESA s/w ready to be used

23 RSNA for Administrators Classroom Sessions Step 2: What & How to Test List your Actors/Profiles that you need to test Review the MESA Test Procedures applicable for each actor that need to be tested Review the Test Procedures for the Peer to Peer testing applicable actors.

24 RSNA for Administrators Classroom Sessions Test Example – Scheduled Workflow Profile (SWF) Figure Administrative Process Flow This case covers both inpatient and outpatient procedures. The patient may be new or known to the current healthcare facility. The following sequence of steps describes the typical process flow when a request is made to perform an imaging procedure on a patient
