Transport Level Interoperability (TLI) Standard

Transport Level Interoperability (TLI) Standards allow information to be exchanged between different healthcare systems in a transparent, secure, reliable and efficient manner. This simplifies and accelerates the rapid integration of new and existing health care applications

Transport Level Interoperability (TLI) Standard                       CAS *

  • Ensures that sensitive health care information remains secure, non-repudiated and private when shared across systems
  • Ensures reliable and efficient end-to-end communication of health care information
  • Enables appropriate routing and dispatching of health care information to designated systems
  • Provides standardized mechanisms, procedures and codes to address transport level exception handling
  • Leverages Service Oriented Architecture and applicable conformance criteria from WS-* specification stack (including WS-Security, WS- Reliability, WS-Addressing, etc.)
  • Provides foundational principles as an input and guidance for implementation and integration of alternative transport capabilities and how to transform existing transport features to be conformant with TLI specification
  • Improves interoperability of systems and enables consistent exchange of health information among health care providers
  • Ensures secure, reliable and accurate transport and exchange of patient health care information
  • Reduces redundancies and increases transport efficiency of health care information
  • Allows for system reuse
  • Reduces the number of implementation choices for health care organizations
  • Leverages standardized web service infrastructure to achieve higher productivity and expedite integration among various EHRS System Components
  • Messaging: HL7 V3.0
  • Terminology: HL7 Terminology Code Systems, SNOMED CT, ICD-10-CA, CCI

* Status Definitions

Canadian Draft for Use (CDFU) - The standard has been developed but it may or may not be implemented or be in use. The standard is considered ready to be used by early adopters: however, change is probable as stakeholders begin using the standard in implementations.

Canadian Approved Standards (CAS) - The standard is in use for the purpose(s) or context(s) for which it was intended. Only those parts of the standard that have been implemented or are in use can progress for consideration as CAS. This decision point signifies that the standard has reached a level of stability and is comprehensive enough such that major changes are not expected.
