ICD-11 RSG MeetingWHO, Geneva

Overview

New features in iCAT Things people want Survey results Feedback

iCAT A collaborative authoring tool for the ICD-11 alpha phase Developed at Stanford as a generic tool that can be

customized for different ontologies, terminologies and classifications

The vision is to use the same conceptual framework and tool infrastructure for the entire WHO-FIC to enable the interoperation of the classifications

Installations already exists for: Intl. Classification of Traditional Medicine (iCAT-TM)

Intl. Classification of Patient Safety (iCAT-PS) Production platform: http://icat.stanford.edu

Demo platform: http://icatdemo.stanford.edu

The Content Model

iCAT = Content Model + User Interface Content Model is the underlying formal structure

that defines the characteristics of a disease (and the fields in iCAT)

Content Model is developed by the HIM-TAG and it is constantly evolving (iCAT has to keep up with it)

Significant changes in the Content Model since last iCAMP (linearization, external causes, functional impact, value sets, short and long definition, index terms, etc.)

New iCAT features Support for linearization and different use cases

Support for external causes

Support for functional properties

Threaded notes

Improved watch functionality and email notifications

Direct links to categories

Change history

Hierarchy management

Improved value set search in BioPortal

Login with OpenId (Google, Yahoo, etc.)

Import/export spreadsheet template

Export to CLAML to generate the print version (Mayo team) Etc. See more on: http://groups.google.com/group/icat-users/web/icat-release-notes

New Orange Logo

Linearizations

Specify the uses of a category (mortality, morbidity, etc.)

Specify the specialty adaptation (Mental Health, Dermatology, etc.)

In a linearization, a category has exactly one parent Select a parent for a particular use (one of the

existing parents, or one of their ancestors) Used to build the classifications for the different

uses and the print version Primarily for the classification experts

External causes

External causes are special: different dimensions and different fields

Dimensions: Intent, Mechanism, Place of occurrence, Activity, Substance use

Value sets from ICECI Keep backwards mapping to ICD-10 Different user interface with different fields

External cause example

External causes – ICD-10 mapping

Functional Properties

Describe the functional impact of a disease Different aspects: Understanding, Communication,

Mobility, Self-care, etc. Value set comes from ICF Check-boxes to expose most common values

Functional Properties

Threaded notes

Notes and discussions are shown in a threaded fashion to enhance the presentation of replies

A user may edit, delete or archive his or her own note, if there is no reply

Threads with new replies pop-up in the notes tree

Watched Entities and Branches

Watched entity

Watched branch

Watch branch: get notified about any change in the branch.

See change list of watched entities and branches after you log in on the first page

Email Notifications about the Watched Entities and Branches

Receive email with the change notifications and discussion notifications

Configure the frequency of notifications (immediate, hourly, daily)

Links to jump directly to the changed category

Change history

Browse the change history of a category

Manage Hierarchy Tab

Import/Export Spreadsheet template

Thank you to Robert Chalmers for providing the macros

Things people want (feedback from iCAMP2)

Import/export to spreadsheets Cloning More collaboration support:

– Notifications

– Filtering of watched entities Better searching capabilities Support for avoiding duplicates

iCAT Usability Survey

We received 14 responses Extremely useful feedback both on the tool, content

model and process Results of the survey are available online*

* http://tinyurl.com/icat-survey

What people liked...

Hierarchy management Clear tab structure nice tree, clear layout, nice UI Ease of navigation, ability to cut and paste

information Integration of features Link with BioPortal

What people did not like..

Lack of:

– synchronization between the tabs (implemented now)

– export/import

– view of all properties in one screen Slow sometimes

Content model:

– too much content

– too complex

– takes too much time to fill in

Missing features

Comments attached to multiple categories Better retirement Revision workflow Preview of classification

What is coming in the very near future

Tree synchronization in the different tabs Improved search capabilities Export/import from an Excel template Widgets for editing index terms Support for severity Support for temporal properties

Feedback and observations

Not enough clarity about:

– Documentation

– Process

– iCAT Features Misconceptions about tool capabilities and where to

find the tool We need:

– Clear and better communication channels between TAGs, WHO-TAGs, TAGs-iCAT team

The good news..

The second good news.. A mock-up for the beta tool

Thank you!
