Experience with AWS Bedrock Description The Agency is expanding the Provincial Health Services Directory (PHSD) to incorporate artificial intelligence capabilities that improve provider discovery, referral quality, and healthcare navigation across provincial digital health applications.

The solution will utilize PHSD provider, practitioner, organization, healthcare service, specialty, location, and service metadata together with clinical referral context to provide intelligent recommendations while maintaining traceability to authoritative source data. AI agents will consume PHSD FHIR APIs, Smile CDR, AWS Health

Lake, the Agency Master Data Management, and other provincial digital health assets to provide grounded responses rather than generative opinions.

The project includes development of reusable AI services, MCP servers, semantic search capabilities, vector-based retrieval, prompt orchestration, evaluation frameworks, and secure integration with SMART on FHIR applications and provincial healthcare systems.

The implementation will emphasize explainability, auditability, privacy, security, and clinical confidence while supporting future AI-enabled healthcare workflows across the Agency.

Responsibilities: Design and develop AI agents supporting intelligent provider and referral destination discovery.

Develop Retrieval Augmented Generation (RAG) pipelines utilizing PHSD healthcare data.

Design and implement MCP servers exposing PHSD functionality to AI clients.

Develop semantic search capabilities supporting provider, practitioner, organization, healthcare service, and specialty discovery.

Integrate AI agents with Smile CDR, AWS Health

Lake, PHSD APIs, Provider Registry, and Master Data Management services.

Develop intelligent referral destination recommendations based on referral reason, specialty, geography, language, service availability, and organizational relationships.





Develop AI services that validate referral completeness and identify missing referral information prior to submission.

Implement explainable AI responses referencing authoritative PHSD records and supporting evidence.

Develop prompt templates, orchestration workflows, tool selection strategies, and AI evaluation frameworks.

Optimize retrieval quality, ranking, semantic search relevance, latency, and operational performance.
