Project Snapshot
 Streamlines data collection at
investigative sites - addresses
Critical Path Opportunity #45
 Continuation of ACRO’s
Initiative
 Started October 2006
 Supported by a collaborative
group of 17 organizations
 Core team of 16 members
manages..
•
•
11 working groups
Comprised of between 8-40
volunteers
 ~190 working group volunteers
 16 Safety data domains
developed
 Consolidated document posted
for public review in May 2008
 Received over 1800 comments
from 46 companies, institutions
and agencies.
 All 3 ICH regions were
represented in the public
comment process

CDASH Purpose & Scope
 Develop content standards for a basic set of global
industry-wide CRF fields to support clinical research
 element name
 definition
 metadata
 Initial scope limited to most commonly collected data
 These CRF standards apply across all therapeutic areas
and phases of clinical development (I-IV)
 Follow CDISC defined standards development process.

5
CDASH Development Steps
 Started with regulatory electronic study
submission standard - Study Data Tabulation
Model (SDTM)
 Focused on CRF Content, not CRF Layout
 Collected > 150 CRF samples across industry
 Evaluated commonalities/differences between
CRF samples
 Documented data points included/excluded with
justifications

CDASH Development Steps
(Continued)
• Agreed on basic CRF collection fields
• Mapped to SDTM
• Defined required terminology with the CDISC
Terminology Team
• Developed CRF question definitions and
completion instructions for clinical sites and
sponsors

How can CDASH be
used today?
• Use as a Content Standard
– Off the shelf Case Report Form content
– Describes relationship between Operational Data and
Submission Datasets
– CDASH represented several file format
• Excel, Word, Proprietary EDC system format
• Potentially unstructured
• Use within Machine-Readable Metadata
– CDASH represented in CDISC Operational Data Model (ODM)
– Vendor neutral system with an independent format
– Hierarchical structure is ideal for re-usable library of components

Implementation to Date
• Adopted by industry, eVendors and other
organizations.
• Utilized as a platform/template to support efforts
around electronic health records (IHE & HITSPI
efforts)
• Harmonized with NCI’s caBIG project.
(CDASH basic fields + Oncology fields = standard CRF in
the oncology workspace)
CDASH has and will continue to facilitate many
positive changes on how clinical data can be
collected.

CDASH Projects–
Why are we doing this???
•
•
•
•
•
•
•
•
Eliminate some of the variety in CRFs
Streamline training & support common understanding
Reinforce collecting only key data
Reduce collection of duplicate data - decreasing the
potential for error
Minimize data queries
Facilitates populating CRFs by eHR without re-entry
(Cuts down on study start time – for all stakeholders)
Better quality of collected data
Facilitates efficient mapping to SDTM for CDASH
implementers
