Clinical Data Acquisition Standards Harmonization (CDASH)
1.0 Introduction
Its a standard way to organize and format the way you collect clinical trial data.
Follow CDISC defined standards development process
Developed to support the streamlining of processes within medical research.
CDASH Standard Version 1.1 Specifications includes 16 domains that are all therapeutic area
agnostic
Download guide at: http://www.cdisc.org/cdash

CDASH Published Documents 33
Mary Thiongo & Harry van Loen, 4th ADMIT Workshop, ITM BELGIUM, 30 NOV-4DEC2015
Why CDASH? 34
2.0 Value of CDASH
Streamline the processes You don’t reinvent the wheel every time when
conducting a study:
reuse of CRFs,
edit checks and output programs
Reuse of analysis programs i.e. do files.
Makes data more usable Data aggregation
Data mining
Data usability
Mary Thiongo & Harry van Loen, 4th ADMIT Workshop, ITM BELGIUM, 30 NOV-4DEC2015
Why CDASH? 35
Sharing research data with your research partners made easy
Integrates the SDTM requirements into CRF
Provides traceability and more transparency to regulators and other s who review your data.

Study #1 – demo.xpt
Data collection with CDASH (paper) 38
The standard CDASH CRF allow efficient data acquisition and efficient data monitoring at the sites.
Leads to more standard SDTM datasets.
Mary Thiongo & Harry van Loen, 4th ADMIT Workshop, ITM BELGIUM, 30 NOV-4DEC2015
CDASH MODEL 39
Harmonize process across
standards
Ensure Harmonization
with other CDISC
standards
Uses an SDTM concept (domain
variable) if available and
possible.
When data collected can
be placed directly into
SDTM variable
Standardize a CDASH variable if there is not an
appropriate SDTM one
CDASH variable is
used that can map to SDTM
Use existing controlled
terminology
That supports:
• Data analysis • Traceability • Data mining
3.0 CDASH Model
Mary Thiongo & Harry van Loen, 4th ADMIT Workshop, ITM BELGIUM, 30 NOV-4DEC2015
CDASH Metadata Tables 40
CDASH standards are presented in metadata tables
• Common header fields • Domains in alphabetical order • Eight columns in each table

Implementing CDASH in your data stream
44
Creating new variables
Creating new domain
Custom domains are created when they are no published domains
The rules for creating custom domains are described in STDMIG
5.0. CDASH Implementation
Mary Thiongo & Harry van Loen, 4th ADMIT Workshop, ITM BELGIUM, 30 NOV-4DEC2015
CDASH Variables 45
Created to address the specific needs of data collection and management.
Not possible to collect data using same data type, controlled
terminology or format with SDTM.
More than one variable is needed for data collection & data management, but will be mapped into a single SDTM variable.
When a single variable can map into more than one place in SDTM.
Mary Thiongo & Harry van Loen, 4th ADMIT Workshop, ITM BELGIUM, 30 NOV-4DEC2015
CDASH Variables 46
Process of creating new variables
Confirm
• Might be in SDTM and not in CDASH
Use existing names
• Look in SDTM • Domains • QNAMs • TESTCD
Create your Own
• Use CDASH/SDTM variable naming fragments to create with similar conventions
Mary Thiongo & Harry van Loen, 4th ADMIT Workshop, ITM BELGIUM, 30 NOV-4DEC2015
Activity-Creating variables 47
Using the SDTMIG V 3.1 or higher & CDASH standard guides ver. 1.1, to complete the activity
Mary Thiongo & Harry van Loen, 4th ADMIT Workshop, ITM BELGIUM, 30 NOV-4DEC2015
Process of creating custom domain 48
• From SDTM Confirm there is no published
domain
• Must be based on a single class:
• Finding, Intervention, Events Determine the one General
Observation class for your custom domain
• Reserved domain codes • Use X,Y.Z 1. X=Interventions 2. Y=Events 3. Z=Finds
Create an appropriate 2 character domain code
• Adding the domain code to the generic variable
from: class, common identifier and timing fields Create the variables
Create a standard mapping into SDTM from your output
Mary Thiongo & Harry van Loen, 4th ADMIT Workshop, ITM BELGIUM, 30 NOV-4DEC2015
Activity- Creating custom domains 49
Using the SDTMIG V 3.1 or higher as a reference, to complete the activity
Mary Thiongo & Harry van Loen, 4th ADMIT Workshop, ITM BELGIUM, 30 NOV-4DEC2015
CDISC
ADMIT – CDISC - considerations
oADMIT will focus on CDASH
oExamining possible cooperation with CDISC
oExploring the 2 Days CDISC course “End-to-End” (which has academics as target audience)
