NHIS Overview
Turkey’s National Health Information System (NHIS) aims to provide a nation-wide infrastructure for sharing Electronic Health Records (EHRs) Currently, Minimum Health Data Sets, called the “Transmission Schemas”, from the Family Medicine Information Systems (FMIS) and the Hospital Information Systems (HIS) to the NHIS servers at the MoH premises The implementation provides Twenty five HL7 v3 based Web Services Sixteen non-HL7 Web Services each of which is specialized to a specific Minimum Health Data Set Transmission Oct. 10, 2008 IHIC 08, Crete, Greece 3
MHDS Web Services Integration Profile
The integration profile is based on the following national and international standards and specifications: The Transmission Schemas are HL7 v3 conformant messages and localized according to the national requirements For transport protocol, HL7 Web Services Profile is used For security, WS-Security Username Token over SSL is required for conformance Codes in the messages must be from the Health Coding Reference Server (HCRS) The id numbers of the doctors in the messages should exist in Doctor Data Bank The patient id numbers in the messages are required to exist and be consistent with Turkey’s MERNIS (Central Demographics Management System) For each Transmission Schema and MHDS, several semantic Business Rules are defined to provide consistency among the values used in the data elements Oct. 10, 2008 IHIC 08, Crete, Greece 4
TestBATN Framework
A generic Web-based Conformance and Interoperability Testing Framework for e-Business standarts and specifications HL7, Integrated Healthcare Enterprises (IHE), OASIS UBL, OAGIS, GS1 eCOM, CIDX, RosettaNet, etc.
How the TestBATN can be used?
Web-based testing service to support vendors to test themselves for conformance and interoperability As a testing and monitoring tool in interoperability testing events As a certification framework As tool for SDOs or interoperability consortiums Oct. 10, 2008 IHIC 08, Crete, Greece 5
TestBATN Features
A Test Execution Model consisting of high level test constructs Provides functionalities to handle or simulate different parts or layers of the interoperability stack Automate the whole testing process Messaging Capabilities (Sending, Receiving, Listening) Data Processing Capabilities Test Assertions Configuration Management User Interaction (set/show scenario requirements, test questions, monitoring test execution) Oct. 10, 2008 IHIC 08, Crete, Greece 6
TestBATN Test Description Language
A computer interpretable XML-based test description language which provides
Flexibility to design Modify Maintain and Extend the test functionality In contrast to a priori designed and hard coded test cases
Provides a graphical environment
Where a test designer can assemble the reusable test constructs to desing a test scenario Oct. 10, 2008 IHIC 08, Crete, Greece 7
Turkey NHIS Test Scenarios
Basic Conformance Test Cases: Tests the ability of the SUTs (HIS or FMIS systems) to send valid “Transmission Schemas” in terms of syntactic and structural constraints The ability of the systems to send HL7 Web Services Profile conformant SOAP (Web Service) messages The ability of the systems to send WSSecurity Username-Token Profile conformant SOAP (Web Service) messages The ability of the systems to use the username and the password assigned to it correctly, as specified in the WS Security Username-Token Profile in the corresponding SOAP header Syntactic validations of “Transmission Schemas” sent by the systems against their corresponding XML schemas Checking if the code systems and the codes used in the “Transmission Schemas” are valid Validation of the “Transmission Schemas” according to the corresponding business rules Oct. 10, 2008 IHIC 08, Crete, Greece 8
Turkey NHIS Test Scenarios
Interoperability Test Cases: Functions as a proxy between the SUTs (FMISs and HISs) and the MoH NHIS Server Internally stores all intercepted messages for further testing Applies the same checks presented in basic conformance test cases and generates its own transmission response based on the profile constraints As the final step, the transmission responses of the MoH Server are validated against the ones generated internally by the TestBATN framework Oct. 10, 2008 IHIC 08, Crete, Greece 9
Turkey NHIS Test Scenarios
Functionality/Semantic Test Cases: Tests whether the information in the transmissions accurately represents the intentional semantics of the FMIS or HIS users (e.g. doctors, family practitioners) A real life scenario with some information requirements are provided to user or users are asked to specify the values The information requirements are tested by semantic validations Performed Tests: Basic Conformance Tests Testing whether the system provides all possible code values to its user for selection, Checking whether the system accurately packs the value selected by the user into the transmission, Testing whether the system (HIS or FMS) has the ability to render this value to its users Oct. 10, 2008 IHIC 08, Crete, Greece 10
NHIS Conformance Testing Event, Izmir 2008
A conformance testing event(connect-a-thon like event), a five-day workshop, is organized by MoH, Turkey in June 2008 in Cesme, İzmir.
200 Test Scenarios
categorized under 25 testsuites are developed for TestBATN During the workshop more than
5000
test scenarios are executed through TestBATN by an avarage of
130 participants
from
55 vendors
After the workshop TestBATN is also deployed to MoH Servers and are still publicly available from web for vendors to test their products for conformance 109 registered users https://212.175.169.50:8443/testexecution/TestExecuti onGUI.html Oct. 10, 2008 IHIC 08, Crete, Greece 11
