This document provides an overview of Fast Healthcare Interoperability Resources (FHIR). FHIR is a standard developed by HL7 for exchanging healthcare information electronically. It includes a consistent data model with various resources, supports different paradigms of exchange like RESTful APIs and documents, and is designed with implementers in mind. FHIR incorporates lessons learned from prior standards and is freely available along with supporting tooling, servers and libraries to facilitate adoption and implementation.
James McClay, MD from the University of Nebraska Medical Center gave a presentation on FHIR (Fast Healthcare Interoperability Resources) at the AMIA Fall Symposium 2019 in Washington DC. The presentation provided an overview of FHIR, including its resources, references between resources, structured and coded data, and use of FHIR for documenting a clinical consultation. FHIR is designed to improve healthcare data sharing and interoperability.

The document discusses FHIR documents and their structure. It notes that FHIR documents are bundles that contain a Composition resource along with other resources like sections, lists, observations, etc. bound together. Documents can be used when persistence of data across multiple resources is needed or when authentication of the full content is required. The document describes how FHIR documents can be communicated by posting the bundle to various FHIR endpoints like the Mailbox, Document/Bundle, or as a transaction to create/update the individual resources. It also notes documents can be posted as a Binary resource or referenced through a DocumentReference resource.
The Clinical Document Architecture (CDA®) is HL7’s
specification for standards-based exchange of clinical
documents. CDA is based on the concept of scalable,
incremental interoperability and uses Extensible Markup
Language (XML), the HL7 Reference Information Model
(RIM), and controlled terminology for structure and
semantics. This tutorial presents the business case for
CDA, its primary design principles, and an overview of the
technical specification.
This document provides an overview of FHIR (Fast Healthcare Interoperability Resources) and its potential uses in New Zealand. It discusses drivers for adopting FHIR like increasing data sharing needs, the limitations of current standards, and how FHIR addresses these through resources, APIs, terminology support and other features. The document outlines FHIR concepts like resources, paradigms for exchange, and use of terminology systems. It proposes several potential early uses of FHIR in New Zealand like patient portals, primary care integration, mobile apps and a record locator service. The presentation aims to show attendees where FHIR fits in New Zealand and encourage further learning and planning pilots.

FHIR - as a new currency of exchange in New ZealandDavid Hay
- FHIR is the latest HL7 interoperability standard that has seen huge international interest from vendors, national bodies, and other standards development organizations.
- FHIR can be used across document, message, REST, and service paradigms using the same core resources. It defines clinical and administrative resources that can be used to store and exchange healthcare information.
- The presentation provides a practical example of how a mobile application could use FHIR resources like Patient, Encounter, Condition, and Observation to record, present, and summarize a clinical encounter for a pediatric patient.
This document discusses various topics related to health data standards and interoperability. It provides an overview of SMART on FHIR, which uses HL7 FHIR and OAuth 2.0 to allow third-party applications to safely and securely access patient data from electronic health records and other healthcare IT systems. It also discusses FHIR Questionnaires and how they can be used to capture structured data from forms and questionnaires. Finally, it briefly introduces the Device Observation profile for representing device-generated observational health data using the FHIR Observation resource.
This document provides an agenda and overview for an HL7 FHIR training course. The morning session will include introductions to FHIR, resources, and the RESTful model. Exercises are planned to apply the concepts. The agenda also includes an introduction to the FHIR data model and more exercises before breaking for lunch. The trainer is identified as Ewout Kramer from Furore in Amsterdam, and he has experience with FHIR and healthcare software development.
Morning session at Vitalis 2016 - giving a high-level overview of the why what and how of HL7 and FHIR. These slides combine background information on the principles that shaped FHIR and the components of FHIR.
This document provides an overview of FHIR (Fast Healthcare Interoperability Resources) and how it can be used to exchange healthcare data. It discusses key FHIR concepts like resources, references between resources, extensions, and how FHIR uses RESTful principles for interoperability. Resources are small units of exchange that can be composed of other resources or reference them. FHIR specifies a RESTful API where resources have URLs and can be retrieved, updated, deleted using HTTP verbs. This allows distributed, standards-based sharing of healthcare information.
The document discusses search capabilities in FHIR, including:
1. FHIR supports searching resources through parameters and queries to address use cases like finding a patient's record or running analytics.
2. Parameters can represent data types like numbers, dates, strings, and references between resources.
3. Indexing resources involves extracting searchable fields and mapping data types between parameters and resource contents.
- FHIR provides a standard way to represent clinical documents as bundles of FHIR resources bound together with a Composition resource similar to a CDA header and narrative.
- Document bundles can be generated from or decomposed into their component resources using FHIR APIs and operations.
- Validating, storing, and exchanging clinical documents as FHIR resources satisfies the same persistence, stewardship, and authentication requirements as CDA documents.

The document discusses SMART on FHIR, a specification for creating medical applications that can run across different electronic health record systems. It was created to facilitate sharing of clinical knowledge through interactive apps. The specification addresses challenges like defining a data model, security protocols using OAuth2 and OpenID Connect, and user interface integration. It also describes using FHIR resources and profiles to define the data contracts apps need to exchange data. The goal is to allow developers to create substitutable apps that improve care without being restricted to a single EHR vendor.

FHIR DevDays 2015 - introduction to FHIREwout Kramer
This document provides an introduction to FHIR (Fast Healthcare Interoperability Resources). It discusses how FHIR resources like Patient, Observation, and DiagnosticReport can be exchanged using RESTful HTTP operations. Resources have defined meanings and can reference each other to link related clinical information. Extensions allow adding custom elements to resources. FHIR supports bundling multiple resources together in a transaction using the Bundle resource. The specification and additional documentation provide help for implementing FHIR-based systems and applications.
The speaker discusses mapping CDA (Clinical Document Architecture) documents to FHIR (Fast Healthcare Interoperability Resources). CDA was difficult to construct and read, while FHIR provides a more streamlined approach. A joint project maps CDA elements to FHIR specifications and profiles to define the relationship between the standards. The goal is a common syntax and resources that support both documents and APIs, with CDA documents eventually represented in FHIR.

Maturity model
Goto the spec – resource list
In general, FHIR is based on resources and extensions. Since extensions represent the local variations in the system we are very concerned about refining this boundary. One of the areas where there is healthy discussion is around the concept of lists.
Clinicians see many types of lists, problems, diagnosis, patient concerns, allergies, meds, etc. From a developer standpoint they are all flavors of a list. So a discussion ensued over how to refine them.
“All documents have the same structure: a Bundle of resources of type "document" that has a Composition resource as the first resource in the bundle, followed by a series of other resources, referenced from the Composition resource, that provide supporting evidence for the document. The bundle gathers all the content of the document into a single XML or JSON document which may be signed and managed as required.
A Message is similar, refers (amongst others) to its author, and contains information about the source, destination and the event that triggered it.
A message contains 1 “data” resource, which is the root of the payload of the message. This is just a normal resource, which in its turn can refer to other related resources.
A Document, no matter how nested, is flattened to a list of entries, the Document’s header being the first.
The document header (and any other the other resources) refer to each other using normal references to reflect the document’s nesting.
Of course, there may be a digital signature (on the whole Bundle) to attest to the content of the document.
Open the FHIR Home Page and point out the following:
Top Menu –
Getting Started – Better than I can do
Documentation – the canonical documents
Each Resource is composed of about 20-40 resource “elements”
Each resource element is defined by:
Name
Cardinality
Type (Data type or structural resource)
Description
Terminology Binding
Other stuff (Comments, Constraints, Summary Flags, mappings, etc)
Complex meaning composed of other datatypes - example identifer, codeableConcept
Eg condition with different specialties
There are some cases where the information provided in an extension modifies the meaning of the element that contains it. Such extensions are known as "modifier extensions".
Implementers SHOULD avoid the use of modifier extensions where possible.
Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
