PCWG Actiue Projects: Status as in 2015

The following is a list of PCWG projects that are currently active and ongoing. Each project are assigned two project co-leads and are currently working to develop domain analysis models (DAM) or HL7 v3 clinical models, and potentially a set of v3 templates for use in C-CDA or other v3 messaging infrastructures.

Project Status
Allergy & Intolerance

This topic covers all interactions related to clinically recorded adverse reactions
Project ID: 881.
Project contact: Stephen Chu;; Elaine Ayres;
Allergy/Intolerance topics: clinical models (HL7 v3 R-MIMs) - published as DSTU.

Harmonization activities with C-CDA R2.x and FHIR - ongoing
Care Plan Project - PCWG

Contacts: Stephen Chu; Laura Heermann-Langford, Russ Leftwich
Care Plan was balloted in 2007 as DSTU. However, a few negative comments had not been resolved and the balloted contents did not achieve DSTU status.
A new project was initiated in 2011. This project resulted in the development of a Care Plan Domain Analysis Model (DAM) . The HDF 1.5 (HL7 development framework) approach will be followed.
HL7 PC will build on the material and knowledge of various groups to develop the DAM.
Project progress:
* The Care Plan DAM was submitted for 2 rounds of informative ballots. All ballot comments were successfully resolved after the September 2014 WGM.
* Changes to the DAM contents are being made in preparation for its publication before the January 2015 WGM
Care Coordination Service (CCS) Model project:
* The PCWG Care Plan team worked in collaboration with the SOA WG on a Care Coordination Services Model project team to define a set of Care Collaboration Services for care plan development and implementation including care activities scheduling and orchestration.
* The CCS specification was also subjected to 2 cycles of ballot. All ballot comments were reconciled successfully
* The CCS specification is being prepared for publication (schedule: January 2015)
Care Plan Clinical Model (R-MIM) and Harmonization project:
* To commence in 2015
Project contact: Laura Heermann Langford,; or Stephen Chu, MD,

There are considerable debates over the concepts of Care Plan, Plan of Care, and Treatment Plan.
A dedicated stream of work has been initiated to address questions and concerns of different stakeholders.
More information on this stream of work can be located by following this link (Type of Plans Differentiation and Definition):

A Coordinated Care Services Functional Model project has been initiated with co-sponsorship of PCWG and HL7 SOA groups:

Health Concern

Concern Tracking and Care statements provide a framework for tracking and managing health concerns.
Project contact: Michael Tan, NICTIS; Stephen Chu; Kevin Coonan, USA
Item itself will be withdrawn. PC will harmonize this with concern tracker and other R-MIMs with Concern.
Project ID: Needs new PSS once preparation work is done

Draft PSS approved by PCWG.
FHIR Clinical Resources - PCWG

This topic covers a number of clinical resources under the stewardship of PCWG.
Contacts: PCWG co-chairs
(NOTE - The medication resources are under the stewardship of HL7 Pharmacy WG)

PCWG will continue to provide review and feedbacks on the published FHIR DSTU Resources for which it has stewardship.
PCWG will also work with FHIR team to develop new clinical resources
These will be ongoing activities

There are three active FHIR related activities of which PCWG is the responsible committee/WG:
* Referral and Transition/Transfer of Care
* Clinical Assessment
* Clinicians on FHIR (renamed from Clinician Connectathon as of May 2015 Paris WGM)

Topics and Discussions of Interest:
* Representing Negation
* Observation vs Condition
* Observation, Clinical Assessment and Clinical Annotation


Projects: Past

Past Projects - with Active and Inactive/Cancelled Status

Other topics the Patient Care TC has defined:

These have their own project numbers, or project scope statements need to be developed and balloted.

This topic is completed and published in the normative edition since 2013.

This topic is completed and published in the normative edition since 2013.
  • Care Statement -- the clinical statement version in the D-MIM for patient Care, currently DSTU.
Will in future versions of Care Provision be replaced by the Clinical Statement CMET A_SupportingClinicalStatement universal (COCT_RM530000UV)
Needs to be split up in a whole set of different topics to allow finding these in the ballot. Current clustering renders it not findable.
  • Concern Tracking -- currently DSTU as part of care structures, to be moved to separate topic level
Needs new PSS and ID by January 2012 to move to normative

  • NOTE:
Each separate Topic needs a new PSS and separate ID around January 2012 once the D-MIM and first Topics Care Record, Query, Transfer have been brought to ballot.

Change Requests

Patient Care has now a formal request for change (RFC) page which can be used to request changes in the ballot materials.

Patient Care Change Requests

Please use this for RFC you have pertaining to Topics, D-MIM, R-MIM, use cases, interactions, walkthrough etc. Those that have been handled by either a motion accepted, and /or models or descriptions being changed are listed under Dispositioned Requests.
