Lessons learned from implementing service-oriented clinical decision support at four sites: A qualitative study.

Area of Science:

• Health Informatics
• Clinical Decision Support Systems
• Electronic Health Records

Background:

• Service-oriented architecture (SOA) is increasingly used for clinical decision support (CDS) integration.
• The Clinical Decision Support Consortium (CDSC) conducted a multi-site study to evaluate SOA-based CDS.

Purpose of the Study:

• To identify challenges and lessons learned during the development and implementation of SOA-based CDS.
• To establish best practices for future SOA-based CDS initiatives.

Main Methods:

• Employed ethnographic investigation utilizing the rapid assessment process.
• Included clinical observation, system demonstrations, and 91 interviews across diverse clinical sites.

Main Results:

• Identified challenges across eight dimensions: infrastructure, content, interface, personnel, workflow, organizational policies, external regulations, and system monitoring.
• Key challenges included performance issues, terminology differences, workflow variability, and the need for a legal framework.

Conclusions:

• Eight best practices were identified for SOA-based CDS: optimize performance, embrace terminology flexibility, foster transparency, develop legal frameworks, support flexible interfaces, dedicate resources, enable peer communication, and improve standards.
• The CDSC successfully implemented SOA-based CDS, offering valuable lessons for developers and implementers.
