What problem does it solve?

Special Purpose SDTM domains (DM, CO, SE, SV) have unique structures that complicate standard observation-class workflows. This skill provides a structured guide and reference for designing, validating, and transforming these domains to ensure CDISC compliance and data integrity.

Core Features & Use Cases

• Domain-specific templates for DM, CO, SE, SV with required and permissible variables aligned to SDTMIG.
• Validation guidance to ensure proper USUBJID construction, CT application, and date logic, with recommended transformation patterns.
• Reference and guidance for linkage between DM, SV, SE, and CO, including handling of visits, demographics, and comments in clinical data pipelines.
• Use Case: A data team mapping trial demographics to DM and aligning visit data in SV while capturing study elements in SE.

Quick Start

Install or load the Special Purpose Domains guidance in your SDTM project, then consult the sample variable definitions and transformation examples to begin constructing your DM, SV, SE, and CO domains consistently.
