Introduction:

Introduction Goal : To provide better and cost effective patient care one needs to exchange healthcare information. Standard : Ability of two or more systems or components to exchange information and to use the information that has been exchanged [ IEEE Standards Computer Dictionary ]

Slide3:

Health Concept Triangle from: SCOTT, P., MACISAAC, P. SAAD, P., et al. An introduction to health terminologies. Brisbane: NCCH, 2002.

Broad Categories:

Broad Categories Vocabulary Content Exchange Transport Privacy, Security and Confidentiality

Common Vocabularies:

Common Vocabularies ICD-9, 10, 11 (WHO) SNOMED-CT (IHTSDO) LOINC (Regenstrief Institute Inc.) CPT-5 (AMA, USA) ICHI (WHO, based on ICD-10-AM) ICD-10 CPS RxNorm (NLM, USA)

Content Exchange Standards:

Content Exchange Standards HL7 v2.x, v3.0, FHIR HL7 CDA R2.0 CDA + CCR (ASTM) = CCD DICOM

Transport Standards:

Transport Standards SOAP ( Simple Object Access Protocol ) XML (W3C)

Security:

Security A symmetric 128 bit fixed-block cipher algorithm capable of using a 128, 192, or 256 bit encryption key An encrypted and integrity protected link to be implemented (e.g., TLS, IPv6, IPv4 with IPsec).

What is Health Level Seven (HL7)?:

HL7 is an ANSI-accredited Standards Development Organization (SDO) operating in the healthcare arena. HL7 v2.x: Communication layer (Interaction and Message models) HL7 v3: Objects layer (Information model – RIM and Document – CDA ) HL7 FHIR : Fast Health Interoperable Resources What is Health Level Seven (HL7) ?

Slide13:

How to Harmonize different standards – e.g ., HL7 and DICOM? HL7 communicates Clinical and Administrative (ADT) data between HIS and RIS DICOM communicates between RIS and PACS for images and DICOM modality work list query So there needs to be a Broker to communicate between HL7 and DICOM IHE Scheduled Workflow ( SWF ) integrates the ordering , scheduling , imaging acquisition , storage and viewing activities associated with radiology exams.
