The National E-Health Transition Authority (NEHTA) is a company established by the Australian, State and Territory governments in 2005 to develop better ways of electronically collecting and securely exchanging health information.
NEHTA
• Lead the uptake of eHealth systems of national significance; and coordinate the progression and accelerate the adoption of eHealth by delivering urgently needed integration infrastructure and standards for health information.
• In 2013-14 NEHTA will continue to drive the national adoption and uptake of eHealth and support the Australian health sector’s transition to the effective use of eHealth.

• Standards & specifications that offer semantic interoperability between disparate systems.
• Provide standard naming conventions.
• Avoids risks of duplication, avoidable expenditure & solutions that cannot integrate/scale across healthcare settings.
• Addresses specific priority clinical processes. Examples:
• Medications Management
• Discharge Summaries
• Referrals
National approach required

Clinical challenge
Clinical records:
• Not only a record for the author
• Essential to inform the next person in the care team
Clinical safety risks of poor quality, ambiguous communication, e.g. prescribing, dispensing and administration errors.
Difficult to establish a person’s medication history reliably and efficiently across the continuum of care.
Desire to:
• make systems more interoperable
• improve data quality
• improve ability to re-use information

“If you’re stumped, why not write an illegible prescription and hope the pharmacist comes up with something?”

Why Terminology?
• Standardised and consistent terms
• Unique identifiers to support communication between computer systems ensuring no loss of meaning
• Foundation products to support National approach
• Clinical uses via Systematized Nomenclature of Medicine Clinical Terms – Australian release (SNOMED CT-AU)
• IHTSDO
• Medicines via Australian Medicines Terminology (AMT)
Clinical Terminologies
Terminologies are:
• Essentially large dictionaries of clinical terms
• Designed for clinical data capture and recording
• For use by humans and computers
Terminologies are not:
• A classification, e.g. ICD-10, ATC
• Designed for statistical reporting or resource uses
• A knowledge base
9 National E-Health Transition Authority www.nehta.gov.au
• A medicines terminology developed in the same way as SNOMED CT
• Delivers standardised identification of brand (trade) products and equivalent generic medicines along with associated components Identifies all commonly used medicines in Australia and can be implemented in clinical information systems to support:
• Prescribing
• Recording
• Reviewing
AMT overview
• Administering
• Supply – including dispensing
• Transfer of information
National E-Health Transition Authority www.nehta.gov.au
What is included in AMT?
• Majority of Registered items from the TGA’s Australian Register of Therapeutic Goods
• Many Listed items from the Register
• PBS dressings, diagnostics and nutritional supplements
• Provision to include non-approved therapeutic goods, e.g. SAS items
National E-Health Transition Authority www.nehta.gov.au
Medicines terminology or medicines information?
• There is a wide range of knowledge about medicines that is not included in a medicines terminology
• Terminology information must always necessarily be ‘true’
• Knowledge information may change over time
• Knowledge can be linked to product descriptions through the terminology
National E-Health Transition Authority www.nehta.gov.au
Terminology or Information?
• Product name, e.g. Panadol
• Clinical indication
• Pack size
• Strength
• Dose Form
• Unit of use
• Adverse reaction
• Relationships between concepts
• Availability
• Synonyms
• Identifier code
• Drug interaction
• Allergy class
• Dose
• Generic name, e.g. Paracetamol
• Contraindication
• Subsidy
• Container
• Price

What are they?
• Clinical scenarios defining how AMT can be used
• However feedback indicated:
• AMT implementation guidance against clinical use cases had been lacking.
• Use cases at the time didn’t provide context
Aim of developing use cases for v3 Beta:
• Improve understanding of how AMT may be used in different clinical situations
• Assist vendors in developing against defined use cases.
AMT v3 Beta – Use Cases
Initial focus:
• To support vendors and NEHTA initiatives (e.g. PCEHR) where the majority of development activity is occurring. This includes:
• General Practitioners (GP) and Specialists using pack based prescribing.
• Community Pharmacist dispensing (pack based)
• Transfer of information between GP Prescribing and Community Pharmacist Dispensing.
• Further use case development will prioritise those supporting electronic medications management and the AMT Roadmap, e.g. dose based prescribing.
Use Case Focus
• Puts use of AMT in context
• Illustrates interactions between Prescribe and Dispense Use Cases
• Includes messages and logical data flows to illustrate the use of the AMT
Prescribe and Dispense Use Case
Prescribing Use Case Goal - use of AMT as the source of the medicines terminology to support:
• Prescription (pack based prescribing) by an authorised prescriber (e.g. GP).
• Generation and exchange of information in a community-based model using an authorised dispenser (e.g. community pharmacy).
National E-Health Transition Authority www.nehta.gov.au
Prescribing Examples
The AMT will support pack based prescribing such as:
• Prescribed for the first time (new): antibiotics, oral medicines, injections, topical preparations, combination pack, modified release medicines etc.
• Prescribed for repeat prescription (repeats): long term medicines etc.
• Prescribed for re-supply of prescription: long term medicines, inhaler, anticoagulant, eye drops, tablets, etc.
• Prescribed for administration in clinics: vaccines etc.
Dispensing Use Case
Goal - use of AMT to support:
• Documentation of pack based dispensing by an authorised dispenser.
• Generation and exchange of information using AMT to dispense medicines.
• Dispensing of pack based prescriptions by an authorised dispenser (e.g. community pharmacist).
• Generation and exchange of information involving an authorised prescriber (e.g. GP).
National E-Health Transition Authority www.nehta.gov.au
Dispensing Examples
The AMT will support pack-based dispensing such as:
• Dispensed for the first time (new): antibiotics, oral medicines, injections, topical preparations, combination pack, modified release medicines etc.
• Dispensed for repeat prescription (repeats): long term medicines etc.
• Dispensed for re-supply of prescription: long term medicines, inhaler, anticoagulant, eye drops, tablets, etc.
