Description

• The Provincial Health Services Directory (PHSD) is enhancing its user experience and integration capabilities to support eReferral workflows directly within electronic medical record (EMR) environments. The work will enable clinicians to find and retrieve appropriate healthcare services and providers from PHSD while remaining within their EMR workflow. The project will enhance SMART on FHIR integration to support EMR launch context, fhirContext, and standards-based FHIR read and write operations. It will also add support for the Ontario Context Management Services (CMS) standard using FHIRCast so that patient, user, encounter, and application context can be synchronized where required across participating applications. The PHSD user interface will be modernized using React and TypeScript best practices, with a focus on responsive provider and service discovery, semantic search, intelligent search suggestions, filtering, and a streamlined eReferral experience. Advanced Google Maps capabilities will be incorporated to support geographic service discovery, including regional and polygon overlays, service clustering, and other map-based visualizations. Backend Spring Boot microservices will be refined to apply user roles, permissions, and entitlements when searching across different PHSD and provincial datasets. The work also includes integration with NetIQ for identity and access management, IBM Master Data Management (MDM), FHIR-based Pub/Sub patterns, REST and FHIR APIs, OpenSearch, PostgreSQL, and supporting AWS cloud services to provide secure, scalable, and reliable interoperability.
