ICD-11 revision process: External assessment now due April 1

Post #317 Shortlink: http://wp.me/pKrrB-42A

This post is the first in a series of updates on the ICD-11 revision process.

Last July, in Call for Expressions of Interest to review the ICD revision process, I reported that the World Health Organization (WHO) Office of the Assistant Director General, Health Systems and Innovation had posted a call for expressions of interest from suitable contractors to conduct an interim assessment of the 11th Revision of the International Classification of Diseases (ICD).

Lead time was four months, with the completed final report targeted for submission to WHO by December 15, latest.

With no sign of a report in the offing, I asked WHO’s Bedirhan Üstün, last week, whether an interim assessment had been delivered in December and did WHO intend to publish a summary report.

Dr Üstün confirmed on January 10 that the external report will now be delivered by April 1 and that it “will certainly be made available.”

So the delivery of this interim assessment has slipped targets by some 15 weeks.

I have no information about the contractors who successfully pitched for the review and no date by which WHO aims to release a copy of the report’s findings (or summary of key findings).

The Call for Expressions of Interest to review the ICD revision process Terms of Reference document can still be downloaded from the WHO website, here:

ICD-11 Beta drafting platform

Go here for the public version of the ICD-11 Beta drafting platform.

According to Slide #4 of this WHO presentation on Slideshare, the Joint Linearization for Mortality and Morbidity and Statistics (JLMMS) was expected to be frozen at certain points during the review process.

If you are registered with the public Beta platform for increased access and interaction with the draft, there are dropdowns from the Info tab for Downloads and Frozen Releases, eg:

Linearization Print Versions

Simplified Linearization Outputs

Linearization Index Tabulations

Frozen Releases

You may find the frozen release downloads here


When viewing the ICD-11 Beta drafting platform bear in mind that the platform may still be subject to freeze and more recent proposals will have been made across all chapters.

From the Contributions tab, you can pull up the Proposals pages for specific terms or view the Proposals List. New proposals are added on a daily basis and date back to July 2014.

Proposals can be filtered according to Proposal Status (Saved; Submitted; External Review, Accepted, Implemented, Rejected etc.) or filtered by Proposal Type.

Before scrutinizing or quoting from the public version of the Beta draft, I strongly advise that you first check the Proposals List for more recent revisions since the public Beta drafting platform may not display the most recent proposals.

You may find later proposals for revisions to the text of definitions and other Content Model descriptors; additions or deletions to Inclusions, Exclusions, Synonyms; deletions or additions of entities; revisions to terminology; proposals for complex hierarchical changes etc. Please also read these Caveats.

Caveats: The ICD-11 Beta drafting platform is not a static document: as a work in progress, it is subject to daily edits and revisions, to field test evaluation and to approval by ICD Revision Steering Group and WHO classification experts. Not all new proposals may survive internal/external review or field testing. Chapter numbering, codes and sorting codes currently assigned to ICD categories may change as chapters, entities, content and parent/child hierarchies are reorganized. The public version of the Beta draft is incomplete; not all “Content Model” parameters display or are populated; the draft may contain errors and omissions of categories and Index terms.
