Overview
ISO/TR 16056-1:2004 - Health informatics - Interoperability of telehealth systems and networks - Part 1: Introduction and definitions - provides a concise introduction to the interoperability challenges of telehealth and establishes the terms, definitions and scope needed for consistent work in this field. The Technical Report includes an informative annex describing a Telehealth Technical Reference Architecture to clarify system components and the elements to consider when formulating requirements. It does not define conformity or interoperability tests or full functional specifications.
Key topics
- Definitions and terminology for telehealth, telemedicine, interoperability and related technical terms - establishing a common vocabulary for stakeholders.
- Telehealth interaction modes: real‑time (synchronous), store‑and‑forward (asynchronous), and media streaming - and their interoperability implications.
- Telehealth Technical Reference Architecture (informative annex) - describes components, interfaces and elements to consider when specifying telehealth system requirements.
- Standards landscape and normative references - the report lists relevant standards and recommendations (examples cited in the document include ITU‑T H.320, T.120 family, G.711 and others) to contextualize telehealth interoperability efforts.
- Interoperability challenges - discusses causes such as broad service definitions, lack of dedicated telehealth standards and the need to coordinate telecommunications and IT sectors.
- Scope boundaries - explicit statement that Part 1 focuses on definitions and introduction, while Part 2 (Real‑Time Systems) and other future documents address specific technical requirements.
Applications and practical value
Who benefits:
- Healthcare providers and organizations - to align procurement, deployment and policy discussions around a shared vocabulary and architecture.
- Telehealth equipment vendors and system integrators - to map product features to reference architecture components and identify relevant standards.
- Standards developers and regulators - to identify gaps and prioritize workstreams for real‑time, store‑and‑forward and streaming interoperability.
- Governments and professional bodies - when developing guidance, procurement specifications, or accreditation criteria.
Practical uses:
- Establishing consistent definitions in RFPs, technical specifications and project scoping.
- Using the reference architecture as a checklist for component‑level requirements (e.g., terminals, codecs, signalling).
- Identifying normative standards to consult when designing interoperable telehealth solutions.
Related standards
- Part 2 of this Technical Report covers Real‑Time Systems (audio, video, data conferencing).
- The document references industry standards (ITU‑T recommendations, CEN/TC 251 reports) that implementers should consult for protocol‑level details.
