infective endocarditis Queensland (ieQ)

ieQ logoieQ is a Prince Charles Hospital initiative to establish Australia’s first clinical and research collaborative supporting improved outcomes for patients with infective endocarditis.

Established in 2017, and facilitated by a Metro North SEED Grant and extensive clinician in-kind support, the collaborative has established a multi-faceted structural platform. In May 2018, the Collaborative received additional recognition and support from The Prince Charles Hospital Foundation “The Common Good”.

Infective Endocarditis [IE] is a relatively rare condition in general practice, but is more common in cardiothoracic referral hospitals such as The Prince Charles Hospital. This condition affects dozens of Queenslanders per year, many requiring open-heart surgery. At least 1 in 10 Queenslanders with this disease will die from it and many more will suffer serious consequences affecting their quality of life. At TPCH, we admit and treat an estimated 60-80 patients with infective endocarditis every year.

Because of the relative rarity of this condition, little is actually known about it. All current guidelines are international, and none specific to Australia. Our leads, representing TPCH, are part of a global effort to expand knowledge about this condition.


  • Under a clinical and research framework, ieQ aims to improve understanding, in an Australian context, of this disease.
  • By having an established expert working group across multiple disciplines, with an affiliated patient/consumer representative, we’ll optimise education, research and translational opportunities.
  • With a focus on parallel clinical engagement and provision of an Expert Advisory Team [initially localised to TPCH but planned to expand state-wide], we can support front-line, evidenced-based, patient care.
  • The enabling of the IE Registry and Biobank [HREC/15/QPCH/60] is the first of its kind in Australia, and is anticipated to provide a strong repository for a broad spectrum of future research endeavours, from biomarkers through to genetics, and epidemiology through to health service utilisation.

Australasian Society for Infectious Diseases

The Australasian Society for Infectious Diseases is the peak professional body for infectious diseases and microbiology in the region and a key stakeholder for government departments, medical colleges and other societies, including international organisations. Membership encompasses Infectious Diseases Physicians, Clinical Microbiologists, Scientists, Infection Control Practitioners, Public Health Physicians, Sexual Health Physicians, Veterinarians and others eminent in the field of infectious diseases. The aims of the society are to:

  • Advance postgraduate education in infectious diseases in Australasia and internationally;
  • Promote research in all aspects of infectious diseases; and
  • Advocate for sound and evidence-based public health policy in matters related to infectious diseases.

Cardiac Soicety of Australia and New Zealand

The Society was constituted with the objective of promoting the highest standards of education, training, research and practice in cardiovascular medicine and surgery through:

a. contributing to the advancement of knowledge of the cardiovascular system and treatment of diseases

b. establishing and supporting the maintenance of professional and ethical standards of practice 

c. facilitation of the education of trainees in cardiovascular medicine 

d. facilitation of continuing professional development in cardiovascular medicine 

e. promotion and defence of equitable access of all Australians and New Zealanders to high quality cardiovascular healthcare; and 

f. promotion of good fellowship among those whose primary interest is the practice of cardiovascular medicine or surgery or allied subjects.

International Society of Cardiovascular Infectious Diseases

ISCVID was founded in the late 1980s to bring scientific awareness to endocarditis, a disease of high morbidity and mortality but with very little organized multinational collaboration. In the early 1990s this society began holding biennial scientific sessions to bring together the community of endocarditis investigators.

American Heart Association

The American Heart Association is the nation’s oldest and largest voluntary organization dedicated to fighting heart disease and stroke. Founded by six cardiologists in 1924, the AHA now includes more than 22.5 million volunteers and supporters. The AHA funds innovative research, fights for stronger public health policies, and provides critical tools and information to save and improve lives.
 Centre for Disease Control and Prevention      

The CDC works 24/7 to protect America from health, safety and security threats, both foreign and in the U.S. Whether diseases start at home or abroad, are chronic or acute, curable or preventable, human error or deliberate attack, CDC fights disease and supports communities and citizens to do the same.

As America's health protection agency, the CDC saves lives and protects people from health threats. To accomplish their  mission, the CDC conducts critical science and provides health information that protects against expensive and dangerous health threats, and responds when these arise.
