1. World Health Organization Classifications, Terminologies, Standards ICD Revision: Where Are We?

2. Overview ICD Revision progress –Current status –Stability: how similar to ICD10 – ICD10AM –Next Steps: Collaborative Authoring Tool improvements Proposals Peer Review Field Trials Other Products …

3. ICD-11 Revision Goals multi-purpose 1.Evolve a multi-purpose and coherent classification public health… –Mortality, morbidity, primary care, clinical care, research, public health… –Consistency & interoperability across different uses 2.Serve as an international and multilingual reference standard for scientific comparability and communication purposes 3.Ensure that ICD-11 will function in an electronic environment. a digital productICD-11 will be a digital product electronic health records and information systemsSupport electronic health records and information systems Link ICD logically to underpinning terminologies and ontologies (e.g. SNOMED, GO, …) ICD Categories “defined” by "logical operational rules" on their associations and details

4. Current Status Frozen September 30 – iCAT continues real time – JLMMS is frozen for review – A new freeze is expected in Dec 2014. Definitions – Top level > 75 %> 10,000 definitions Linearization errors < 465 (from 10K) Duplicates< 105 (from 3K)

5. The ICD Foundation Component is a collection of ALL ICD entities like diseases, disorders... It represents the whole ICD universe. In a simple way, the foundation component is similar to a “store” of books or songs.

6. The ICD Linearizations A linearization is a subset of the foundation component, that is: Fit for a particular purpose: reporting mortality, morbidity, or other uses Jointly Exhaustive of ICD Universe (Foundation Component) Composed of entities that are Mutually Exclusive of each other Each entity is given a single parent

7. Foundation Foundation: ICD categories with - Definitions, synonyms - Clinical descriptions - Diagnostic criteria - Causal mechanism - Functional Properties Find Term SNOMED-CT, International Classification of Functioning, Disability and Health (ICF)… Linearizations Mortality Morbidity Primary Care

22. Print Versions

23. ICD 2014 September release Print version release includes: Frozen “Joint Linearization for Mortality and Morbidity Statistics” ( Vol. 1 Equivalent). The ongoing work on iCAT will go ahead in further completing the ICD definitions and improvements. A future release is also planned in December. Thereafter the releases will be made whenever necessary. Incremental changes from August Release are given in a separate document to enable tracking which parts remained stable – which parts changed.

26. Taxonomic Check Taxonomic check includes the aggregation equivalence: with the Primary Care versions – PC Intermediate Resource version  renamed: Intermediate Version – PC Low Resource version  renamed: Short Version With Specialty Versions – see whether the specialty extensions roll up to JLMMS ( if this was the chosen option)

27. Annotation Document & Reviews An updated Annotation Document identifies the architecture, principles and known issues. Reviews by Mortality and Morbidity TAGs included for common reference and guiding future work

28. STABILITY ANALYSIS A Foundation based equivalence programme identifies equivalences between ICD-10 and ICD-11. a TRANSCODING table between ICD-10 and ICD-11 in excel format A CROSSWALK gives the detailed output in excel format The ICD11 Beta Browser will display the ICD-10 equivalents accordingly.

32. ICD Index Print Index is about 1900 pages with some lead terms running several pages. About 3000 ICD10 Index terms are “missing”. A human judgement is being made as to whether they are necessary and once included they point to the right code. Sublead terms missing Improvements planned
