Working Model Pilot – DM Rules

• Objective: to get many different perspectives and experiences in order to refine the approach for the remaining domains/ observation classes. Pilot Exercise – DM Domain

• Using draft rules template extract all text that may indicate DM rules from SDTM 1.4/SDTMIG 3.2

• Record all potential interpretations• Reconciliation team to harmonize and consolidate• Full team review of rule metadata and potential

interpretations

Rules Team Scope

• Extract all business logic and data conformance rules? What about data quality? Is the output expected to be comprehensive or only

what is not captured e.g. DDT attributes, structural SDTM compliance? Inferred data quality?

• Rules metadata model: English-like, not concerned with rigorous application of

CT or rule syntax? More principle than law.

VS. Consistent syntax and CT, but perhaps too granular,

lacking readability. More law than principle.

• Implementable in Share? Do we know?

Rules Questions

• Screen failures - expected to be included or excluded? Data for screen failure subjects, if submitted, should be

included in the Demographics dataset, with ARMCD = “SCRNFAIL" and ARM = “Screen Failure”

Conditional rule? Add parameter to TS?

• ACTARM, ACTARMCD – implementation in complex trials are problematic, and are values expected to match TRTxxA (ADaM)?

• Population flags – expected? Conditional rule? Add parameter to TS?

Rules Questions

• Professional patients, patients shopping sites/arms – multiple DM records?

• What is the rule? Additional guidance needed. Multiple records / different SUBJIDs VS. One record per patient/USUBJID

• Map secondary to SUPPDM

• Where can a variable be used? Class level rules?

Rules Questions

• Managing Duplicate Rules• Rules class heirarchies – e.g.

If Core Variable Status = Req then Variable must exist Vs. USUBJID must exist, ARM must exist, etc.

• Overall Guidance Heirarchy SHARE (Future)

• SDTM– Class

»Domain

• Can children refine / restrict parent rules?
