Fast Healthcare Interoperability Resources


Fast Healthcare Interoperability Resources (FHIR) is a next generation standards framework created by HL7.

Fast Healthcare Interoperability Resources combines the best features of HL7's v2 , HL7 v3 and Clinical Document Architecture (CDA) product lines while leveraging the latest web standards and applying a tight focus on implementability.

Fast Healthcare Interoperability Resources solutions are built from a set of modular components called "Resources". These resources can easily be assembled into working systems that solve real world clinical and administrative problems at a fraction of the price of existing alternatives. Fast Healthcare Interoperability Resources is suitable for use in a wide variety of contextsMobile Appss, Cloud computing communications, Electronic Health Record-based data sharing, server communication in large institutional Health Care Providers, and much more.

There are also number of Open Source based tools that can foster worldwide adoption of the HL7 standards

Fast Healthcare Interoperability Resources intent would be to migrate from the current practice of exchanging complex Clinical Document Architecture (CDA) documents to FHIR exchange sets of simpler, more modular and interoperable FHIR JSON Objects

Why Fast Healthcare Interoperability Resources is better #

FHIR offers many improvements over existing standards:
  • A strong focus on implementation – fast and easy to implement (multiple developers have had simple interfaces working in a single day)
  • Multiple implementation libraries, many examples available to kick-start development
  • Specification is free for use with no restrictions
  • Interoperability out-of-the-box– base resources can be used as is, but can also be adapted for local requirements
  • Evolutionary development path from HL7 Version 2 and CDA – standards can co-exist and leverage each other
  • Strong foundation in Web standards– XML, JSON, HTTP, OAuth, etc.
  • Support for RESTful architectures, seamless exchange of information using messages or documents, and service based architectures
  • Concise and easily understood specifications
  • A human-readable serialization format for ease of use by developers
  • Solid ontology-based analysis with a rigorous formal mapping for correctness

Fast Healthcare Interoperability Resources requires any Protected Resource MUST document which version of FHIR applies to the resources it offers.

Fast Healthcare Interoperability Resources and Authentication#

FHIR servers should authenticate the clients. The server may choose to authenticate the client system and trust it, or to authenticate the individual user by a variety of techniques. For web-centric use, OpenID Connect may be used to authenticate users and OAuth may be used to authenticate and/or authorize the users. The Smart-On-FHIR profile on OAuth is tightly integrated with FHIR and is the preferred method for using OAuth.

The HEART Profile is a set of privacy and security specifications that enable an individual to control the authorization of access to RESTful health-related data sharing APIs, and to facilitate the development of interoperable implementations of these specifications by others.

Fast Healthcare Interoperability Resources Classifications#

Fast Healthcare Interoperability Resources is a resource that are classified into 6 sections:
  • Clinical - The content of a Clinical Data
  • Identification - Supporting entities involved in the care process
  • WorkFlow - Manage the healthcare process
  • Financial - Resources that support the billing and payment parts of FHIR
  • Conformance - Resources use to manage specification, development and testing of FHIR solutions
  • Infrastructure - General functionality, and resources for internal FHIR requirements

Fast Healthcare Interoperability Resources Tense#

One of the most fundamental aspects of a Fast Healthcare Interoperability Resources is tense - where it fits into the timeline. Some Fast Healthcare Interoperability Resources are records of past events, some are plans for the future, etc. This table summarizes the categories:
PastA record of an event that has happened
PresentA record that serves an exchange in real time
FutureA record that describes a future intent
OngoingA record that is maintained over time that tracks the state of a patient
UnrelatedA record that doesn't relate to time (e.g. a fixed entity)
Note that even future records end up in the past after the event they are concerned with passes.

Fast Healthcare Interoperability Resources Security Considerations[3]#

Fast Healthcare Interoperability Resources is not a security protocol, nor does it define any security related functionality. However, FHIR does define exchange protocols and content models that need to be used with various security protocols defined elsewhere.
