An exploration of quality gaps in SDTM implementation activities and ideas on how to
address these gaps through appropriate resourcing
Dianne Weatherall: 2013-04-11

GOAL
• Adoption of CDISC standards has led to:– new processes (aCRF, metadata, programming)– new responsibilities
• Goal: to discuss the “best” SDTM team to implement the new process

DEFINE THE PROBLEM
• Define what is wrong with the current setup

ROOT CAUSE OF QUALITY ISSUES
• Lack of understanding of SDTM – WHY?1 2 3
Lack of skills Lack of training Expensive
It is complicated Too much room for personal preference
Customer specific implementations
Unclear process Too many cross-functional teams involved
Companies are too silo’ed
Lack of expert support Lack of skills It takes time and effort to become an expert

ROOT CAUSE OF QUALITY ISSUES
• Lack of understanding of clinical data – WHY?1 2 3
Lack of data / clinical skills of teams
Clinical data is complicated Highly un-normalized Database structures are often developed for data entry and clinician preference, not CDASH/SDTM standards
The CRF changes over time Therapeutic areas have complicated study designs (e.g. cohort changes)
Poor planning from the study design stage
![Page 7: An exploration of quality gaps in SDTM implementation activities and ideas on how to address these gaps through appropriate resourcing Dianne Weatherall:](https://reader031.fdocuments.in/reader031/viewer/2022032516/56649c7c5503460f94930ca9/html5/thumbnails/7.jpg)
ROOT CAUSE OF QUALITY ISSUES
• Non-standard data – WHY?1 2 3
Legacy studies SDTM standards are relatively recent
Customer specific requirements Customer specific implementations
Customer legacy systems are not CDISC-compatible
Therapeutic areas have complicated study designs (e.g. cohort changes)
Poor planning from the study design stage

SUMMARY OF ROOT CAUSES
• Company silo’s • Lack of data skills of Biostats teams • Lack of CDASH / SDTM skills of Data teams • Time and effort to build expertise • Customer-specific • Poor study planning • Expensive - join a user group!

Other things to consider
• Submissions– Continuity across studies– Consistency across studies– Change control– Bottle necks (reviewer team)
• ADaM / statistical output resourcing

RESOURCE CRITERIA
FROM• SDTM after design• Just save costs• Allocate availability
TO• SDTM during design• Invest in expert team• Look at continuity
