CDASH Serious Adverse Event (SAE) Supplement v 1.0 is Now Available


This supplement expands the Adverse Event (AE) domain in the current CDASH standard to include additional data elements for the capture of serious adverse event information in an SAE form. This supplement also facilitates Sponsor generation of an E2B message for electronic reporting of an Individual Case Safety Report (ICSR) to Health Authorities.

**CDISC CDASH-SAE Addendum Public Review Comments**



CDASH Version 1.1 was developed via CDISC’s consensus-based standards development process (see COP-001), which included comments from organizations in all three ICH regions (US, Europe and Japan).  The standard describes the basic recommended data collection fields for 18 domains; these include common header fields, demographic, adverse events, and other safety domains that are common to all therapeutic areas and phases of clinical research.   In addition, CDASH V 1.1 includes implementation guidelines and best practice recommendations, regulatory references and other information on the CDASH project.

CDASH User Guide


The CDASH User Guide (CDASH UG) is now available.  The CDISC UG provides CDASH implementation examples, including CDASH to SDTM mappings, CDASH ODM files and a library of example CRFs that have been created in several different data collection systems, including paper examples.  The CDASH team plans to update the CDASH UG with additional examples as they become available.

CDASH ODM.xml, Data Definitions and CRF Examples

The Operational Data Model (ODM) is a vendor neutral, platform-independent format for interchange and archive of research data. Click here for more information about ODM.


The CDASH-ODM file provided below is an implementation of ODM that provides examples of basic case report form (CDASH) content in XML. The XML may require modification to be applicable for a particular study or to be implementable in a particular database system.  


The PDF file provided below includes the data definitions and CRF examples that have been created from the ODM XML.  The primary purpose of these examples is to provide a starting point for the creation of CDASH CRFs.

Library of CRF Examples

A library of example CDASH CRFs has been created in several different data collection systems, including paper examples.  The CDASH team plans to update the CDASH UG Example CRF library with additional examples as they become available.

CDASH CRF Examples



If your organization would like to submit example CRFs to the User Guide team to be included in the CDASH CRF Examples library, please send a representation (e.g., pdf, screen shot) of the CRF, a description of the use case you are addressing, and the name of the EDC or other system in which you created the example CRF to Shannon Labout. 

All submitted example CRFs should be de-identified (i.e., remove the name of your company, name of your investigational product, etc, from the CRF example). The CDASH team will review all examples submitted.  Conformant examples of CRFs will be added to the library, provided permission to publish the example is given by the EDC or other vendor in whose system the example is represented.




CDASH Team Projects


CDASH Version 2.0

 The CDASH team is currently working towards the publication of CDASH Version 2.0.  This version will include minor updates and clarifications.  We anticipate that this new version will be available in Q1 2014.


 In addition, the CDASH Team has been working on a number of related and collaborative projects that include the development of new domains and associated documents for medical devices and therapeutic area CRFs.  Following are short summaries about these CDISC projects: 



CDISC Device Standard 


 The CDISC Device team is comprised of members from the CDASH and SDS team and is working to develop the basic collection fields and the submission variables and mappings to support a majority of device studies. The Device team recently published draft SDTM constructs for public comment.  Work on the collection aspects will commence as soon as the submission elements are agreed. 



CDISC Therapeutic Area CRFs

The CDASH team is collaborating with other CDISC teams to develop therapeutic area (TA) specific CRFs to be used together with the safety CRFs described in the CDASH standard.  Draft TA specific CRFs will be released for public review according to the CDISC consensus process. 



CDASH Serious Adverse Event Domain 


This CDASH-E2B sub team is working to identify and describe the E2B basic data fields that are collected from investigative sites.  This new Serious Event domain is intended to reduce the need for separate SAE reporting processes and the inevitable duplication of data collection that occurs between the SAE and clinical databases.  The draft standard will be released for public review according to the CDISC consensus process. 




The CDASH team also supports the development and review of a REDCap CDASH CRF library.  



CDASH User Guide team 


The CDASH User Guide team will continue to add example CRFs and other implementation tools to the CDASH User Guide.
