Structured representation for core elements of common clinical decision support interventions to facilitate knowledge...

Area of Science:

• Health Informatics
• Computerized Clinical Decision Support
• Information Standards

Background:

• Lack of standardized methods for representing clinical decision support (CDS) interventions hinders interoperability and knowledge sharing.
• Existing approaches do not adequately define the structural components of diverse CDS intervention types.

Purpose of the Study:

• To identify essential requirements for representing five common CDS intervention types: alerts and reminders, order sets, infobuttons, documentation templates/forms, and relevant data presentation.
• To propose and validate a shareable XML schema for CDS knowledge representation.

Main Methods:

• Development of an XML schema to represent CDS interventions and their core structural elements (metadata, clinical scenarios, inputs, outputs, logic).
• Validation of the schema by creating CDS artifacts for 22 interventions aligned with 2011 Meaningful Use criteria.
• Creation of custom style sheets for human-readable rendering of XML files and establishment of a public web portal for sharing.

Main Results:

• Successful validation of the proposed XML schema through the creation of 22 diverse CDS artifacts.
• Demonstrated the feasibility of representing key structural components of various CDS intervention types.
• Established a public web portal for sharing CDS knowledge artifacts, facilitating broader access and collaboration.

Conclusions:

• The developed XML schema provides a standardized approach for representing CDS interventions, addressing a critical gap in current practices.
• The study highlights limitations in existing standards and offers insights for future development in CDS knowledge representation and sharing.
• The proposed schema and shared artifacts can enhance the interoperability and adoption of clinical decision support systems.
