ICD could be a key part of this, but risks marginalisation if it does not become  computable . Preliminary examination of injury and external causes reveals no fundamental barrier to such change, BUT & Making the full transformation will require investment of much thought, time and money. The question How much should and can be done for ICD-11? The answer will affect how the TAG does its work.b%  `%  ` cStructural issuesCode template and allowed ranges ICD-10 allows: Injury S00.0-T99.9 External Causes V00.0-Y99.0 Clinical modifications of ICD-10 allow up to 3 more digits The question: What will ICD-11 allow? N!/e!/ebStructural issuesdPre- and post-coordination ICD-10 is heavily weighted towards pre-coordination, but: Aspects of injury and external causes classification are well suited to post-coordination. For example: Treating Place as 4th character in Ext Causes chapter forces creation of many rarely used compounds & is structurally constraining. More post-coordination in ICD-10 clinical modifications : Modifier compound codes: e.g. Burns: location/depth + area Implicit compounds: e.g. Head injury: intracranial injury (fact of + type + volume) + loss of consciousness (fact of + duration) + skull fracture (fact of + part of skull) + whether fracture is compound (i.e. communicates with a wound) Multi-axial compounds e.g. Nature/anatomical location of injury [ compounds] + Intent/mechanism + Place of occurrence + Activity when injured The question: What will be allowed in ICD-11?Z:ZZ:ZZZ Z:| n:   eStructural issuesMultiple codes per record Post-coordination presumes that multiple codes are allowed per record Allowed under ICD-10 (& clinical modifications)? typically  Yes for morbidity and  No for mortality The question: What will be allowed in ICD-11 versions? bx5*x5* dStructural issuesVersions and how they relate Plans for ICD-11 have foreshadowed versions for: Mortality Morbidity also: Primary care, Clinical specialty care, & Research Case distributions & data needs differ between settings: the same  short list of categories will not be optimal for all different needs result in different structural preferences (e.g. underlying cause for mortality; reason for current admission/current contact for clinicians) In which way will ICD-11 provide for the use cases? One version (trying to allow for diverse needs, more or less well) Single hierarchy of versions (i.e. collapsed/expanded versions)  Underlying detailed version, from which specific versions are projected? (Perhaps with a  base version in common)Z1ZMZ9ZZ4ZZ1M94 hSummary & conclusionsGood prospects To improve the Injury and External Causes chapters of ICD. ICD-11 injury and external causes chapters should: Embody enough innovation to reflect change & make the effort worthwhile Serve a wider range of uses and users than ICD-10 Retain backward comparability sufficient for continuance of important trends Keys to progress Early decisions on certain aspects of structure and rules: Essential for efficient progress to drafting The decisions should have input from users and custodians of ICD-10 & developers of ICD-11 a timetable for development (6/12?), refinement & decision (12/12?) Realism about resources needed and available Ambitions must match the time, money and people available. o<.<o  <.<VInvitation to participate Submit specific issues, and proposals to remedy them Express interest in participating in debates that may emerge Respond to issues raised in this paper To: james.harrison@flinders.edu.au (#/P:;<=>?@ABCDEB  0` 33` Sf3f` 33g` f` www3PP` ZXdbmo` \ғ3y`Ӣ` 3f3ff` 3f3FKf` hk]wwwfܹ` ff>>\`Y{ff` R>&- {p_/̴` 3f3ff>?" dd@,?" dd@% @ ` n?" dd@   @@``PJ    @ ` ` pF@`F@` >6(    60!  `}  T Click to edit Master title style! !  0$  `  RClick to edit Master text styles Second level Third level Fourth level Fifth level!
