This confluence page in the HL7 Devices Projects space provides an initial "starter" home for collecting content and discussion notes during the PHN project initiation phases within HL7.   Once the project is approved, this page can be moved to the appropriate confluence space / lead working group as appropriate.

Zulip discussion stream has been created HERE.


In HL7, the Personalized Health Navigation (PHN) discussion was begun 11 May 2023 during the HL7 WGM in New Orleans.  The presentations (see Resources below) included the following overview slide:

Personalized Health Navigation – 

Enables & empowers individuals

to intentionally pursue their

own health and wellness journey...

By utilizing intelligent navigational technologies,

integrating comprehensive information

from their daily lives &

factoring in all relevant knowledge sources

To personalize, optimize and guide their

self-directed health & wellness & healthcare activities &

To facilitate coordination with their 

family, community, caregivers and healthcare team

All to attain their desired goals.

A primary differentiator between PHN and other projects within HL7 is its focus on person (not necessarily patient) directed health and wellness navigation, with healthcare coordination when appropriate and optimized to return to a state of optimal health and wellness.   

The project focuses on the WHO definition of Health:  a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.

HL7 PHN Project

HL7 PSS-2197 Personalized Health Navigation Project Proposal was reviewed and approved for distribution by the HL7 Devices WG , and completed HL7 review and "Accepted" on  .  This proposal begins the broad discussion of PHN within the HL7 community and proposes the following three general project deliverables:

  1. PHN White Paper – A balloted paper that will establish the broad HL7-wide perspective on advancing PHN
  2. PHN FHIR Implementation Guides – Based on the consensus established in the white paper
  3. HL7 PHN Implementation Community – including FHIR Connectathon track(s), open source implementations, education materials, etc.

Next Milestones:

  1. PSS-2197 Project Proposal Approval - COMPLETE () Accepted!!! - this will establish both the scope and subject relevance within the HL7 community + identify those groups that are actively interested in participation 
  2. PSS-2240 PHN Project Scope Statement (PSS)  - Drafting underway, to be submitted for approval end of July  / August - the formal project plan, including primary work group and supporting groups

Joint HL7-ISO PHN Program

The HL7 PHN Project will be pursued as a joint effort in collaboration with the ISO/TC215/WG11 Personalized Digital Health Informatics 9472 PHN Standards family.  As proposed in the kick-off presentation (see Resources below):
