This lecture is an introduction about myself and gives an overview of the course objectives, expected content across all three parts, and some important disclaimers to keep in mind.
This lecture provides an introduction to healthcare interoperability, tracing its evolution from early integrated health information systems to today’s need for seamless data exchange. It explains the levels of interoperability and highlights the critical role of healthcare standards in enabling secure, efficient, and meaningful communication across healthcare systems.
This lecture covers the topic of one of the oldest HL7 standards, called HL7 version 2, its history, development paradigms, and usage.
This lecture continues with the development of HL7 standards and discusses the next generation of HL7 standards, the methodology behind it, and how it influenced subsequent standards.
This lecture focuses on a specific domain within the HL7v3 standard that has gained greater popularity: Clinical Document Architecture, or CDA.
When discussing HL7 standards, it's crucial to mention openEHR as well. This lecture briefly introduces openEHR, which isn't under the HL7 umbrella but has influenced the development of HL7 FHIR as well.
Recap of the previous section and quick look at what's ahead.
This lecture begins the FHIR introduction by discussing the reasons for the emergence of a new standard, the history of its development, and the personalities behind it.
The aim of this lecture is to provide you with a quick introduction to the 'FHIR' specification, its various sections, and how to navigate them.
This lecture covers the realm of FHIR resources, explaining what they are, why they're important, and how to navigate them.
This lecture provides a hands-on demonstration of how to explore and retrieve FHIR resource instances using examples from the FHIR specification and the HAPI FHIR JPA Server.
Healthcare data is conveyed through elements with specific data types. This lecture covers the foundations of data types in FHIR, including primitive and complex data types, along with other related topics.
Searching for FHIR resource instances is an essential aspect of the FHIR standard, and it can be both exciting and challenging. This lecture explores the basics of the FHIR search mechanism, how it operates, and the steps needed for successful utilization.
This lecture explains in detail a few confusing search paradigms that exist in FHIR, specifically chained and reverse chained searches, and result modifiers.
This lecture helps you ensure that the created or retrieved instance is a valid FHIR instance. It introduces several ways to automate the validation process on design, testing, and application levels.
This lecture aims to help you achieve semantic interoperability by introducing FHIR terminologies, standard sections, and related aspects.
The HL7 FHIR standard does not cover all aspects of the healthcare IT world; there are other related standards that may work in conjunction. This lecture introduces some of them.
This lecture offers guidance on how to bring the flexible FHIR specification to life in real-world healthcare scenarios.
As a closing remark, I'd like to provide students with additional reading materials that this course is based on, as well as offer consulting services.
There are likely several hundred or even thousands of standards that healthcare organizations may need to comply with, depending on country or region, the type of services they provide, and the regulatory bodies governing them.
In this lecture we will only review a few standards that have directly or indirectly influenced the development of the HL7 Fast Healthcare Interoperability Resources or FHIR standard.
The primary audience for this course is software developers, software testers, interface analysts, system integrators, and other professionals seeking an organized guide to the HL7 FHIR standard documentation.
As a software developer who is just starting to learn HL7 FHIR and wants to grasp the basics as quickly as possible, I have organized the learning process in a way that prioritizes the topics I recommend you learn first, what you should absorb next, and which topics can be skipped for the time being.
This approach is designed to help you optimize your learning and get up to speed with the FHIR standard as efficiently as possible.
Upon completion of this course, you should have a solid understanding of FHIR in general, know how to navigate different sections of the standard effectively, and gain insight into the third-party standards necessary to implement your specific healthcare requirements successfully.
