HL7 for Implementation and Maintenance Staff
Session 1 – HL7 Introduction
This session will give an understanding of why messaging is used in healthcare and the standards that are used. The session will conclude with a view of the scope of HL7 and the concepts and principles used in messaging.
•Why Healthcare Messaging
•Healthcare Messaging Standards
•Scope of HL7, HL7 Concepts and Principles
Session 2 – Concepts and Principles
Give an understanding of what HL7 is and its concepts. It concludes with an introduction into messaging types, trigger events and interface engines.
•What Hl7 is/is not?
•Trigger Events, Message Types
Session 3 – Project Implementation
This session views the building of HL7 messages and the elements involved in the construction. It goes into detail of structure and the roles of each message component.
•Fields/Tables, Conformance, Tools
Session 4 – Planning for the Future
Objective This last session looks into the future of HL7 and its migration to further versions. It will also investigate the version migration process. The session will conclude with an evaluation of the course.
HL7 for programmers and interface developers
This course is for HL7 programmers, interface developers and dedicated Implementers and is designed to provide the skills for the analysis testing, problem tracking and activation of phases of an HL7 project. Attendees will learn HL7 design; trigger concepts, message formatting rules, data types, enhanced acknowledgement rules, identifiers, and table translation issues. Course work includes hands on exercises.
On completion of this course, attendees will have gained a deep understanding of HL7 messaging processes and practices, with the ability to effectively read, understand, analyze, design, develop, and test
HL7 messages for implementation.
Session 1 – Healthcare Messaging Standards
This session will give an understanding of why messaging is used in healthcare and the goals that are achieved. The session will conclude with a view of the scope of HL7 and the concepts and Principles used in messaging.
•Why Healthcare Messaging
•Purpose & Scope of HL7
•Development of HL7
Sessions 2 & 3 – Concepts and Principles
This session gives an understanding of what HL7 is and its concepts. It introduces messaging types and triggers events and then goes into the building of HL7 messages and the elements involved in the construction. It goes into detail of the structure and the roles of each message component.
•What HL7 is/is not?
Session 4 – HL7 Building Blocks (Data Types)
This session discusses in detail concepts of data types and all important data types.
•Data Types 1 (Alphanumeric/numeric/identifiers)
•Data Types 2 (Demographic/coded)
•Data Types 3 (Date-Time/miscellaneous)
Session 5 – Building Messages and Segments
In this session details of messages their segments (down to the field level) will be fully discussed. Most important messages and segments shall be covered.
Session 6 - Sending & Responding
This session examines the role of acknowledgements and message responses in HL7 and introduces the use of queries and continuation messages.
•Acknowledgements & Responses
Session 7 – Conformance & Specification
This session examines conformance in HL7 messaging and the reason for its use. Conformance profiles are examined in detail as well as the conformance tools that are available.
•Conformance Profile 1 (Use case/dynamic)
•Conformance Profile 2 (Static)
Session 8 – Filling the Gaps
This session completes the HL7 concepts by examining many of the peripheral parts of HL7 messaging and concludes with the relationship that HL7 has with XML.
•HL7 & XML
Session 9 and 10 – Hands-On
By this point of time, the resources will be well acquainted and confident with the theoretical aspects of HL7 V2.6. Session 9 and 10 will now focus completely on hands on. Each resource will be trained to dissect each message and understand each field with nothing more than their knowledge and notepad.exe. They would then be provided a real life scenario and trained to construct an HL7 message with notepad.exe.
Following this they will be trained to receive and send these messages using freeware tools, to get an understanding of real world requirements.
Next, they will be trained in the use of different freeware applications that would allow them to quickly accept, read, analyze and modify/correct HL7 V2.6 messages. They would also learn to use these tools to quickly construct messages.
Finally, the resources will learn how to create a conformance profile, using a popular open-source tool.
Session 11 – What’s next? HL7 V3
This last session looks into the future of HL7 and its migration to further versions. It will also investigate the version migration process. The session will conclude with an opportunity to answer any lingering questions/issues.
