The Primary Care Research Object Model (PCROM): a computable information model for practice-based primary care...

Area of Science:

• Clinical research informatics
• Health services research
• Biomedical informatics

Background:

• Growing chronic disease burden necessitates large, community-based clinical trials.
• Existing clinical trial management systems require a robust primary care research information model.
• The need for standardized models to facilitate primary care research is critical.

Purpose of the Study:

• To develop a primary care research object model (PCROM) for community-based clinical trials.
• To support the design, execution, and analysis of practice-based clinical trials.
• To integrate with existing clinical research models like the Biomedical Research Integrated Domain Group (BRIDG) model.

Main Methods:

• Utilized Unified Modeling Language (UML) to create use cases, activity diagrams, and a class model.
• Focused the initial PCROM scope on randomized clinical trials (RCTs) in primary care.
• Validated the PCROM with global domain experts and compared it against the BRIDG model.

Main Results:

• A class diagram and definitions for primary care RCT components were developed.
• 45% of PCROM objects mapped directly to BRIDG, 37% showed differences, and 18% did not map.
• Demonstrated significant overlap and areas for integration with the BRIDG model.

Conclusions:

• The PCROM serves as a vital link between current research models and practical implementation of primary care clinical trial systems.
• The model's high correspondence with existing research models validates its comprehensiveness.
• Existing research models need extensions to fully accommodate the specific needs of primary care research.
