Everything about health information standards like openEHR, FHIR, SNOMED CT, LOINC and more.
SNOMED allows creating extensions for terms not in its release, adhering to specific rules for standards. Extensions can map to pre-coordinated concepts or require post-coordination, published with a namespace for semantic interoperability.
In this comprehensive guide to the Clinical Knowledge Manager, understand how the CKM drives the core principles of openEHR - ensuring and facilitating standardization, interoperability, governance and community development.
SMART on FHIR enables health apps to connect with EHRs securely, including OAuth2 and OpenID for authorization and authentication. It supports standalone and EHR app launches, emphasizing security, PKCE support, and specifying access through scopes.
Refsets in SNOMED CT allow subsets for specific use cases, enabling standard compliance and external sharing. They cater to language, mappings, and situational needs with a mandatory regeneration post-SNOMED release.
CMS's Patient Access Rule mandates HL7 FHIR API for data access, provider directory via API, payer-to-payer data exchange, and daily federal-state data exchanges, enhancing interoperability and patient data access.
SMART on FHIR defines two ways in which clients can authenticate - symmetric (shared secret) and asymmetric (public key) client authentication.
FHIR leads healthcare interoperability, enabling secure data exchange across systems. CMS/ONC's initiatives like Blue Button 2.0, BCDA, and DPC pilot utilize FHIR for Medicare data sharing, enhancing patient access and care coordination.
Medblocks, initially focused on blockchain for medical record interoperability, evolved to address healthcare data challenges utilizing openEHR, FHIR, SNOMED, and LOINC for standardized data format and terminology, and using OAuth2 for secure data access
PHC system by Kyushu University & Grameen Communications uses eHealth and telemedicine, integrates openEHR and FHIR, serving 45,000+ since 2010, now includes Tele-Pathology and Tele-Eye Care.
Use SNOMED CT Browser for exploring clinical concepts, synonyms, relationships, and semantic tags. Supports ECL for advanced search and MRCM for rules validation.
Medblocks UI, open-source alternative to Better EHR Studio for auto-generating forms from openEHR templates, now available under Apache 2 license.
Set up a SNOMED CT terminology server using Docker and Hermes: Clone Hermes, index SNOMED CT files, execute index.sh, start server with docker-compose up.
