Page History

The Products Hierarchy is primarily comprised of primitive concepts, and in many areas, replicates the organization of concepts in the Substance Hierarchy. Because the concepts in the Products Hierarchy are mostly primitive concepts or not defined using the proximal primitive modeling methodology, the classifier cannot be leveraged, relevant changes in the Substance Hierarchy are only reflected in the Products Hierarchy with manual intervention, and the Products Hierarchy cannot be effectively and efficiently maintained. Most concepts in the Products hierarchy could be fully defined with the attributes present in the existing concept model, excluding concepts that contain product strength or represent product role.

1. Updates per SLA agreement

1. Completed Jan 2017

RFP-Drug concept model

1. Draft mode, analysis and creation of Master Position Statement. Drugs area review of the impact of EMA approach for the Medicinal Products Dictionary.

1. Completed June 2016
   
   

1. Assessment and partial cleanup of 17k Concepts (total number in product hierarchy)

1. Completed Oct 2016-delivery of 6k for Alpha Release. Feedback on content has led to next step resolution phase.

Drugs Products Hierarchy Project

1.Alpha Release

There are multiple aspects to this project including:

Concepts representing product role:

Concepts representing product role need to be removed from the Product Hierarchy because the association between a product and its role represents knowledge that is outside of the scope of an ontology. The product role may not be always and necessarily true as required by the SNOMED CT concept model. The product role may vary between Member countries or be dependent on dose form or strength, resulting in incorrect inferred relationships

Groupers in Product Hierarchy:

Groupers, including concepts that represent chemical class, mechanism of action, body system, and dose form, in the Product Hierarchy are inconsistently represented. The groupers include concepts that cannot be fully defined, leading to ongoing maintenance concerns. Editorial guidance for moving forward and recommendations for existing concepts that do not conform to the editorial guidelines must be agreed upon.

a.Recommendation for retirement of Product Hierarchy concepts representing product role

b.Recommendation for representation of roles in SNOMED CT, likely via a Role Hierarchy in the Qualifier value Hierarchy

i.Recommendations to be delivered to the Editorial Advisory Group

1. a&b i.Complete 2016

Medicinal Entity and Medicinal Form Concepts in the Product Hierarchy:

Medicinal Entity and Medicinal Form concepts in the Product Hierarchy are inconsistently represented. They include concepts that cannot be fully defined and inconsistent terming conventions, leading to ongoing maintenance concerns. Editorial guidance for moving forward and recommendations for existing concepts that do not conform to the editorial guidelines must be agreed upon.

1.Proposal documented, with two parts:

a.Recommendation for editorial guidelines for Medicinal Entity and Medicinal Form concepts

b.Recommendation for disposition of existing concepts that do not conform to the editorial guidelines

1. a &b on track to finish by Dec 2016, dependent on Project Group Sign-off with a scope 0f 80/20 with drugs first and vaccines etc. second.
   PSK: Both a&b have been started and updated as the model is being built

1. Updates per SLA agreement

1. In progress for July in alignment with the SNOMED CT International Release Schedule
   PSK: Completed

1. Draft Drugs Model has been completed by external Consultant. The end deliverable has been posted on the Drugs Product group and the Modelling AG confluence sites. Next steps are to progress to a draft version which can be presented at the October Conference.

1. In Progress, Q1 2017.
   PSK: Completed

1. Assessment and partial cleanup of 17k Concepts (total number in product hierarchy)

1. Feedback on content has led to next step resolution phase.
   PSK: on-going as part of Drugs/Substance re-modelCompleted

      ii. Recommendations to be delivered to the Drug Project Group after agreement from the Editorial Advisory Group
      
      
2. Detailed deployment plans for both will be developed after the proposals are accepted and dependent on the Alpha release.
   
   
3. Proposal documented, with two parts:
   1. Recommendation for editorial guidelines for groupers
   2. Recommendation for disposition of existing concepts that do not conform to the editorial guidelines
      
      
4. Detailed deployment plan will be developed after the proposal is accepted

1.a&b ii - In Progress, interim solution delivered to Editorial AG, agreed and test in Alpha, long term solution in progress it was delivered to the Drug Project group as the long term solution is being finalized. and will become part of 2.

2. In Progress -March 2017(dependent on drug concept model & Substance project)

PSK: plan to deliver in July 2018Jan 2019

3.In Progress - testing and analysis done. Looking for feedback from working group on recommendations. Dependent on working group response to finish in 2016 in may be Jan/Feb 2017 also in part to holiday constraints.

PSK: in progress and will be deliverd July 2018

 4. March 2017 (dependent on drug concept model)

PSK: plan to deploy in July 2018

Medicinal Entity and Medicinal Form concepts in the Product Hierarchy are inconsistently represented. They include concepts that cannot be fully defined and inconsistent terming conventions, leading to ongoing maintenance concerns. Editorial guidance for moving forward and recommendations for existing concepts that do not conform to the editorial guidelines must be agreed upon.

1. Detailed deployment plan will be developed after the proposal is accepted

1. March 2017(dependent on drug concept model)

PSK: Terming and Semantic tags being finalised, will be included in July 2018

Comprehensiveness of Content:

A plan for the ongoing maintenance of the Product Hierarchy must be developed, including the ability to leverage content created by national extensions. Planning for this work will begin as the previously described aspects to the project are resolved.

1. Maintenance Plan for Product Hierarchy

1. TBD -Dependent on Drug Concept model to be delivered Oct 2017

Re-model of Drugs hierarchy

1. Groupers
2. Dose forms
3. MPs, MPFs and CDs
