The HL7 Pocket Guide. A Practical Reference for Healthcare IT Consultants, Interface Analysts, and Interoperability Professionals - Alison Owen NRMA PH.D.

Healthcare systems depend on the seamless exchange of clinical and administrative data. From patient registration to diagnostic testing and results reporting, healthcare applications must communicate accurately and efficiently to support safe, coordinated care.

The HL7 Pocket Guide provides a clear and practical introduction to the HL7 messaging standard-the foundational technology that enables interoperability between healthcare systems.

Designed for healthcare IT professionals, interface analysts, consultants, developers, and health informatics students, this guide breaks down complex HL7 concepts into easy-to-understand explanations supported by visual diagrams, workflow illustrations, and quick-reference tables.

Inside this guide you will learn how HL7 messaging supports the flow of healthcare information across systems such as Electronic Health Records (EHR), Laboratory Information Systems (LIS), Radiology Information Systems (RIS), pharmacy systems, and billing platforms.
