stakeholder organisations as possible were invited to participate in the Allergy Summits and the development of the
National Allergy Strategy. These organisations are listed in Appendix G.

Foreword
Allergic diseases have become increasingly important chronic disease and public health issues in Australia and other
developed countries over the last two decades, contributing to increased demand for medical services, significant
economic cost of care and reduced quality of life of people with allergic diseases and their carers. Currently affecting
more than 4 million Australians, the rapid and continuing rise of allergic diseases is therefore a serious public health
issue that requires action by all levels of government and the community.
To address these issues, the Australasian Society of Clinical Immunology and Allergy (ASCIA) and Allergy & Anaphylaxis
Australia (A&AA), as the leading medical and patient organisations for allergy in Australia, have developed the first
National Allergy Strategy for Australia in collaboration with key stakeholder organisations.
ASCIA and A&AA strongly believe that the development and implementation of the National Allergy Strategy is the
most effective way to address chronic disease and public health issues and to provide an effective and coordinated
plan to guide future actions to optimise the management of allergic diseases in Australia. Cost effective solutions are
available and through a coordinated and planned approach many issues can be addressed by collaboration between
stakeholders in all regions of Australia. Implementation of these solutions has the potential for significant health and
economic gains to be made through prevention, early intervention, community education and awareness as well as
better access to diagnostic and therapeutic allergy services.
Recommendations contained in the National Allergy Strategy have been developed with extensive consultation
involving health professionals, consumers and industry, including an Allergy Summit held in August 2014.
The National Allergy Strategy will help to:
n A ddress the most important issues in allergic diseases that currently affect patient care.
n R ecognise allergic diseases as important chronic disease and public health issues by all levels of government.
n Provide direction to government agencies.
n P revent allergic diseases, the most cost effective way to address the current allergy epidemic.
n P romote and expand existing best practice healthcare management.
n E nsure consistency in education, training, preventative measures and healthcare policies throughout Australia.
n R educe unnecessary duplication of effort within and between different regions.
n F ocus attention and research efforts on key allergic disease issues.
The National Allergy Strategy is the first comprehensive initiative in Australia that sets out to improve the assessment
and treatment of all forms of allergic diseases. It is intended to be a national response to the rise in allergic diseases
and will provide a long term plan with realistic directions for short to medium term actions. Our intention is for this
document to be used by state and federal governments, healthcare funders, medical practitioners, other healthcare
professionals, consumers, researchers and research funders, to guide future policies and actions relating to allergic
diseases in Australia.
We look forward to working with all stakeholders in the implementation of the National Allergy Strategy.

Mission, Goals and Guiding Principles
Mission
The National Allergy Strategy mission is to improve the health and quality of life of Australians with allergic diseases and
minimise the burden of allergic diseases on individuals, their carers, healthcare services and the community.
Goals
1. Standards of Care
D evelop standards of care to improve the health and quality of life of people with allergic diseases.
2. Access to Care
E nsure timely access to appropriate health care management for people with allergic diseases.
3. Information, Education and Training
I mprove access to best-practice, evidence-based and consistent information, education and training on allergic
diseases for health professionals, people with allergic diseases, consumers, carers and the community.
4. Research
P romote patient-focused research to prevent the development of allergic diseases and improve the health and quality
of life of people with allergic diseases.
5. Prioritised Chronic Disease
Recognition of allergic diseases as a prioritised chronic disease and National Health Priority Area.
Guiding principles
The following principles have guided the development of the National Allergy Strategy:

In understanding the impact of allergic disease in the community it is important to be aware of some important principles:
r
n P eople with allergy are not always sick and therefore are not always patients. g
n Patients are people who are currently accessing care for their allergic disease. y
n Consumers are people who are not currently accessing care for their allergic disease, but may do so in future.
s
n Carers (including parents/guardians, families and other carers) also need consideration as they are not patients, but t
