The Fast Healthcare Interoperability Resources (FHIR, {{IPAc-en|f|aɪər}}, like fire) standard is a set of rules and specifications for the secure exchange of electronic health care data. It is designed to be flexible and adaptable, so that it can be used in a wide range of settings and with different health care information systems. The standard describes data formats and elements (known as "resources") and an application programming interface (API) for exchanging electronic health records (EHR). The standard was created by the Health Level Seven International (HL7) health-care standards organization.

FHIR builds on previous data format standards from HL7, like HL7 version 2.x and HL7 version 3.x. But it is easier to implement because it uses a modern web-based suite of API technology, including a HTTP-based RESTful protocol, and a choice of JSON, XML or RDF for data representation.{{Cite web|url=https://www.hl7.org/fhir/|title=Welcome to FHIR|last=|first=|date=2019-11-01|website=HL7.org|publisher=|access-date=2021-02-12}} One of its goals is to facilitate interoperability between legacy health care systems, to make it easy to provide health care information to health care providers and individuals on a wide variety of devices from computers to tablets to cell phones, and to allow third-party application developers to provide medical applications which can be easily integrated into existing systems.{{cite journal

FHIR provides an alternative to document-centric approaches by directly exposing discrete data elements as services. For example, basic elements of healthcare like patients, admissions, diagnostic reports and medications can each be retrieved and manipulated via their own resource URLs.

Architecture

File:FHIR resource graph.png

FHIR is organized by resources (e.g., patient, observation).{{cite web|title=Fast Healthcare Interoperability Resources® (FHIR)

|publisher=eCQI Resource Center|url=https://ecqi.healthit.gov/fhir}} Such resources can be specified further by defining FHIR profiles (for example, binding to a specific terminology). A collection of profiles can be published as an implementation guide (IG), such as The U.S. Core Data for Interoperability (USCDI).{{cite web |url=https://www.healthit.gov/sites/default/files/draft-uscdi.pdf |title=Draft U.S. Core Data for Interoperability (USCDI) and Proposed Expansion Process |publisher=USA HHS |accessdate=27 November 2019}} The ONC anticipates finalizing USCDI v4 in July 2023.{{Cite web |title=USCDI ONDEC |url=http://www.healthit.gov/isa/ONDEC |access-date=2023-05-30 |website=www.healthit.gov |language=en}}

Because FHIR is implemented on top of the HTTPS (HTTP Secure) protocol, FHIR resources can be retrieved and parsed by analytics platforms for real-time data gathering. In this concept, healthcare organizations would be able to gather real-time data from specified resource models. FHIR resources can be streamed to a data store where they can be correlated with other informatics data. Potential use cases include epidemic tracking, prescription drug fraud, adverse drug interaction warnings, and the reduction of emergency room wait times.{{cite web

In January, 2018, Apple announced that its iPhone Health App would allow viewing a user's FHIR-compliant medical records when providers choose to make them available. Johns Hopkins Medicine, Cedars-Sinai, Penn Medicine, NYU-Langone Medical Center, Dignity Health and other large hospital systems participated at launch.{{Cite news|url=https://www.apple.com/newsroom/2018/01/apple-announces-effortless-solution-bringing-health-records-to-iPhone/|title=Apple announces solution bringing health records to iPhone|work=Apple Newsroom|access-date=2018-08-09|language=en-US}}

In 2014, the U.S. Health IT Policy and the Health IT Standards committees endorsed recommendations for more public (open) APIs.

The U.S. JASON task force report on "A Robust Health Data Infrastructure" says that FHIR is currently the best candidate API approach, and that such APIs should be part of stage 3 of the "meaningful use" criteria of the U.S. Health Information Technology for Economic and Clinical Health Act.{{cite news | url=http://www.modernhealthcare.com/article/20141016/NEWS/310169945 | title=EHR interoperability solution offered by key IT panels | work=Modern Healthcare

It would then be possible for medical records systems to migrate from the current practice of exchanging complex Clinical Document Architecture (CDA) documents, and instead exchange sets of simpler, more modular and interoperable FHIR JSON objects.{{cite news

A collaboration agreement with Healthcare Services Platform Consortium (now called Logica) was announced in 2017.{{Cite web|url=https://www.healthcare-informatics.com/news-item/interoperability/hl7-teams-healthcare-services-platform-consortium-fhir-development|title=HL7 Teams with Healthcare Services Platform Consortium on FHIR Development {{!}} Healthcare Informatics Magazine {{!}} Health IT {{!}} Information Technology|website=www.healthcare-informatics.com|language=en|access-date=2017-03-30}} Experiences with developing medical applications using FHIR to link to existing electronic health record systems clarified some of the benefits and challenges of the approach, and with getting clinicians to use them.{{Cite web|url=https://www.healthcare-informatics.com/article/interoperability/slow-fhir-will-much-hyped-standard-turbo-charge-interoperability-or-maybe|title=Top Ten Tech Trends 2017: Slow FHIR: Will a Much-Hyped Standard Turbo-Charge Interoperability—Or Maybe Not Quite? {{!}} Healthcare Informatics Magazine {{!}} Health IT {{!}} Information Technology|website=www.healthcare-informatics.com|language=en|access-date=2017-03-30}}

In 2020, the U.S. Centers for Medicare & Medicaid Services (CMS) issued their Interoperability and Patient Access final rule, (CMS-9115-F), based on the 21st Century Cures Act. The rule requires the use of FHIR by a variety of CMS-regulated payers, including Medicare Advantage organizations, state Medicaid programs, and qualified health plans in the Federally Facilitated Marketplace by 2021.{{Cite web|title=CMS Interoperability and Patient Access final rule {{!}} CMS|url=https://www.cms.gov/Regulations-and-Guidance/Guidance/Interoperability/index|access-date=2020-09-22|website=www.cms.gov}} Specifically, the rule requires FHIR APIs for Patient Access, Provider Directory and Payer-to-Payer exchange.

Proposed rules from CMS, such as the patient burden and prior authorization proposed rule (CMS-9123-P),{{Cite web|title=CMS Proposes New Rules to Address Prior Authorization and Reduce Burden on Patients and Providers|url=https://www.cms.gov/newsroom/press-releases/cms-proposes-new-rules-address-prior-authorization-and-reduce-burden-patients-and-providers|access-date=2021-05-21|website=www.cms.gov}} further specify FHIR adoption for payer-to-payer exchange. The CMS rules and Office of the National Coordinator for Health IT (ONC) Cures Act Final rule (HHS-ONC-0955-AA01){{Cite web|title=ONC 21st Century Cures Act Final Rule|url=https://www.healthit.gov/curesrule/|access-date=2021-05-21|website=www.healthit.gov}} work in concert to drive FHIR adoption within their respective regulatory authorities.

Further, other agencies are using existing rule-making authority, not derived from the Cures Act, to harmonize the regulatory landscape and ease FHIR adoption. For example, the U.S. Department of Health and Human Services (HHS) Office of Civil Rights (OCR) has proposed to update the HIPAA privacy rule (HHS–OCR–0945–AA00){{Cite web|title=HHS Proposes Modifications to the HIPAA Privacy Rule to Empower Patients, Improve Coordinated Care, and Reduce Regulatory Burdens|url=https://www.hhs.gov/about/news/2020/12/10/hhs-proposes-modifications-hipaa-privacy-rule-empower-patients-improve-coordinated-care-reduce-regulatory-burdens.html|access-date=2021-05-21|website=www.hhs.gov|date=10 December 2020 }} with an expanded right of access for personal health apps and disclosures between providers for care coordination. Unlike the CMS and ONC final rules, the OCR HIPAA privacy proposed rule is not specific to FHIR; however, OCR's emphasize on standards-based APIs clearly benefits FHIR adoption.

=Brazil=

In 2020, Brazil's Ministry of Health, by the IT Department of the SUS, started one of the world's largest platforms for national health interoperability, called the National Health Data Network, which uses HL7 FHIR r4 as a standard in all its information exchanges.{{Cite web|title=RNDS – Ministério da Saúde|url=https://rnds.saude.gov.br/|access-date=2020-11-10|language=pt-BR}}

=Israel=

In 2020, Israel's Ministry of Health began working towards the goal of promoting accessibility of information to patients and caregivers through the adoption of the FHIR standard in health organizations in Israel. Its first act was to create the IL-CORE work team in order to adapt the necessary components for localization and regulation in the health system in Israel. The ministry, in cooperation with the Nonprofit Organization 8400, created the FHIR IL community, whose purpose is to encourage the adoption of the standard in the Israeli healthcare system while cooperating with healthcare organizations and the industry.{{Cite web|url=https://en.fhir-il-community.org/israel-core/|title=Israel Core|last=|first=|date=2022-08-07|website=fhir-il-community.org|publisher=|access-date=2022-08-07}} As part of a joint activity of the Ministry and 8400, a number of projects were launched for the implementation of FHIR in health management organizations (HMO) and hospitals, alongside other projects that are being independently promoted by healthcare organizations.{{Cite web|url=https://outburn.co.il/blog/fhir-israel/|title=FHIR In Israel – An Overview|last=|first=|date=2022-02-28|website=outburn.co.il|publisher=|access-date=2022-08-07}} In addition, the Ministry of Health allocated budgets to the HMOs and other organizations for the purpose of establishing organizational FHIR infrastructure.

In the 2020 Eli Hurvitz Conference on Economy and Society, run by the Israel Democracy Institute it was estimated that the cost of implementing central FHIR modules of in the Israeli healthcare system is estimated at about 400 million NIS over 5 years.{{Cite web|url=https://www.idi.org.il/media/15311/health.pdf|title=מוכנות מערכת הבריאות למצבי משבר|last=|first=|date=2020-12-16|website=idi.org.il|publisher=|access-date=2022-08-07}} In 2023, the Israeli government began a legislative process to promote the sharing of information between organizations in the Israeli health ecosystem for the benefit of the patient, with an emphasis on patient empowerment and reduced information blocking.{{Cite web|url=https://moj.my.salesforce.com/sfc/dist/version/download/?oid=00D1t000000uX5h&ids=0683Y00000Tg0GP&d=%2Fa%2F3Y000002Lf35%2F0yWSM8LV0HE5TM_ChfZ0VBBI2ph.zsE.zGLYGcTy0mA&asPdf=false|title=תזכיר חוק ניוד מידע בריאות, התשפ"ג-2023|last=|first=|date=2023-01-24|website=www.tazkirim.gov.il|publisher=|access-date=2023-02-14}} The proposed legislation also refers to the need to standardize the data by adopting the FHIR standard and utilizing standard terminologies, such as SNOMED-CT, both in source systems and in the data exchange process. The sharing of information will be with the patient's consent, and this consent will be given according to data buckets.{{Cite web|url=https://outburn.co.il/blog/israeli-health-data-mobility-law-proposal/|title=Everything You Need To Know About The Health Data Mobility Law|last=|first=|date=2023-02-02|website=outburn.co.il|publisher=|access-date=2023-02-14}}
