## Outline * Interoperability * APIs * HL7 * FHIR * IHE Connectathon * Discussion

Interoperability

  • Extent to which systems and devices can
    • Exchange data
    • Interpret that shared data
  • Essential for
    • Continuity of care
    • Monitoring & Evaluation
    • Public Health Surveillance

Interoperability

πŸ—£ Vocabularies

Interoperability


Thacker SB, Qualters JR, Lee LM. Public health surveillance in the United States: evolution and challenges. MMWR Suppl. 2012;61(3):3-9.
# APIs * Application Programming Interfaces * Clearly defined protocol for inter-application communication * Exist at all levels - Operating system - Libraries and frameworks - Remote (RPC & Web)
# REST * Representational State Transfer * Built on HTTP (GET, POST, etc) * URIs

APIS

# HL7 **Overview** * Health Level 7 (OSI model) * Est. 1987 * ANSI/ISO πŸ‘πŸΌ * Mission: To provide standards that empower global health data interoperability
# HL7 **Standards** * HL7 v2 & v3 * CDA * CCD * Arden syntax * FHIR
