HL7 standards benefit everyone

Data standards provide the common language that lets different digital systems work together - so everyone can securely access and use the right health information when and where they need it.

standards benefit everyone everywhere
standards are a community effort

HL7 is a community effort

HL7 standards are developed through the dedicated collaboration of over 4,000 volunteers worldwide who represent healthcare vendors, providers, payers, policy makers, consultants and others.

Here are some ways that HL7 members benefit from active support and participation:

  • Help make healthcare better for everyone
  • Jump-start innovation and speed time to launch on interoperability projects
  • Future-proof your business by staying ahead of standards and trends
  • Learn and collaborate with peers, customers, competitors, and potential partners
  • Influence new standards in ways that matter to your business

“What I like about HL7 is that it's very mission-driven. There's very much a sense of higher purpose. I really feed off the opportunity to connect with others who are passionate and involved about interoperability.”

—Tate Gilchrist, InterSystems


Straight from the Source

Designed for easy implementation, HL7's Fast Health Interoperability Resources (FHIR) standard combines the best of earlier HL7 standards with the latest web technologies for health interoperability that's astonishingly quick and cost-effective to develop.

For organizations considering FHIR as a cure for interoperability headaches, HL7 is your source for all things FHIR.

“HL7 FHIR is the HTML of healthcare.”

—John Halamka, MD, CIO, Beth Israel Deaconess Medical Center

Clinicians and healthcare providers

The continuum of care is critical in improving patient health. HL7 FHIR promises to integrate health data from separate silos to deliver continuous information. 

Why HL7?

HL7 is your source to learn about FHIR and connect with others working on the same challenges.

"Participating in standards requires investment, but there's a high return on that investment through more successful participation in initiatives to reduce costs, create revenue, speed time to market, and ease reporting."

- James McClay, MD, University of Nebraska Medical Center

"With the exponential increase in the amount of data about humans, clinicians need to roll up their sleeves and get involved with HL7 so we can contribute to building standards that work in the context of patient care."

- Russ Leftwich, MD, InterSystems

How you can get involved:

Join an HL7 Work Group

HL7 has many work groups relevant to clinicians and healthcare providers, including in the areas of anesthesia, clinical decision support, clinical quality, emergency care and patient care. These work groups fall under the HL7 Clinical Steering Division, which defines the requirements and solutions to support the needs for communication information related to the creation, management, execution and quality of messages, services, resources and documents.

Clinicians on FHIR

This is a hands-on program developed by the HL7 Patient Care Work Group for those familiar with clinical workflows to challenge FHIR resources and build simple FHIR profiles around abbreviated clinical use cases. It also provides clinical expertise to the technical FHIR Connectathons and seeks to education and evangelize other clinicians about FHIR.

Reducing Clinician Burden Project

This project is managed by the HL7 Electronic Health Records (EHR) Work Group. It focuses on clinician burden and burnout (including time and data quality burdens) as it relates to the use of EHR/HIT systems. It considers the following: clinical practice at the point of care; regulatory, accreditation, administrative, and payer mandates; EHR/HIT system design functionality, usability and implementation; and data quality and usability. The project is reviewing reference sources to document the substance, impact and extent of clinical burden in order to use the findings to influence the future direction of HL7 standards development efforts.

HL7 FHIR provides access to clinical data such as precision medicine and clinical decision support and advances value-based care by improving work flow, care quality and quality reporting.

Why HL7?

HL7 is your source for the latest FHIR solutions to improve health and control cost across health populations.

"As payers we need to stay engaged in the interoperability standards setting process lest our growing needs for provider collaboration and member information will go unmet."

- Joe Miller, Director of Strategy and Innovation, AmeriHealth Caritas (remarks from an ONC meeting)

"The healthcare industry has spoken about patient-centric healthcare for years, but major stakeholders like payers, providers, and government agencies had designed and procured solutions that were best suited for institutions rather than how patients actually wish to consume care. True "patient-serving" innovations and delivery system transformation requires payer/provider collaboration from the start– and it is here that FHIR can play a valuable role. The AHIP Innovation Lab is proud to help HL7 operationalize meaningful shifts that enable "patient-serving" initiatives to achieve optimal utilization levels across the multi-stakeholders in our ecosystem– these types of collaborative innovation models are being proven more and more frequently, with less time to market, and are creating a viable path to outcomes driven healthcare for the consumers we all have the privilege of serving."

- Rahul Dubey,SVP, Innovations and Solutions- AHIP, Founder of the AHIP Innovation Lab

"In a collaborative effort with health providers, health plans are rapidly moving toward alternative payment methods that are value-based, leveraging clinical and financial data to provide consumers better care with better outcomes at a lower cost. By adopting HL7 standards that are capable of resolving many of the healthcare IT ecosystem barriers, we can achieve consumer-first, affordable healthcare delivery."

- Frank Viviano, Director of Technology Strategy, Data Exchange Solutions, Cambia Health Solutions
