Cardiac arrest is one of the leading causes of sudden death worldwide. Without immediate medical intervention, survival rates are extremely low. However, in the Australian state of Victoria, individuals who experience cardiac arrest have a significantly higher chance of survival compared to most places in the world. Thanks to rapid emergency response systems, bystander intervention, and an extensive network of publicly accessible defibrillators, Victoria has set a global benchmark in cardiac arrest survival rates.

The Case of Austin Blight: A Testament to Quick Response

Seventeen-year-old Austin Blight had no warning signs when he collapsed at the gym due to sudden cardiac arrest. In that critical moment, gym staff sprang into action, administering cardiopulmonary resuscitation (CPR) and using an automated external defibrillator (AED) to restore his heartbeat. Their swift actions ensured his survival until paramedics arrived, highlighting the importance of early intervention in saving lives.

Since his medical emergency in 2024, Austin has returned to school to complete his studies and is back to his regular workout routine, demonstrating how quick response can mean the difference between life and death. His survival story is just one of many in Victoria, where cardiac arrest survival rates are among the highest globally.

Victoria’s Impressive Survival Statistics

The 2023/24 annual report from the Victorian Ambulance Cardiac Arrest Registry sheds light on the state’s groundbreaking advances in emergency response. Victoria now boasts the best cardiac arrest survival rate in Australia and ranks third globally, trailing only King County in the U.S. and Denmark.

Key findings from the report include:

  • 79% of witnessed cardiac arrests received immediate bystander CPR.
  • 141 cases involved public use of an AED, the highest recorded number to date.
  • 422 patients survived to hospital discharge.
  • 84% of those discharged returned home to their families.
  • 41% survival rate to hospital discharge, a remarkable increase from 36% in 2022/23.

Why Victoria Leads in Cardiac Arrest Survival

1. Early Bystander CPR and AED Use

A significant factor behind Victoria’s success is the high rate of bystander CPR. Nearly four out of five people who experience cardiac arrest in public receive immediate chest compressions, greatly improving survival odds. Additionally, the increasing presence and use of AEDs have played a crucial role in preventing fatalities.

2. Publicly Accessible Defibrillators

Victoria has more than 7,500 publicly accessible defibrillators, making it easier for bystanders to provide life-saving shocks before emergency medical services arrive. Studies show that when defibrillation occurs within the first few minutes of cardiac arrest, the chances of survival can be as high as 70%.

3. The GoodSAM App: Mobilizing First Responders

Ambulance Victoria’s GoodSAM app is an innovative tool that connects cardiac arrest victims with registered responders nearby. Integrated with the triple-zero emergency service, the app alerts volunteers who can provide CPR and defibrillation before paramedics arrive. In the past year alone:

  • 17,327 registered responders have joined the GoodSAM network.
  • 793 cases were attended to by volunteer responders, ensuring quicker interventions.

4. Strong Emergency Medical Services (EMS) Network

Victoria’s EMS network, including Ambulance Victoria, operates efficiently to ensure rapid response times. Trained paramedics equipped with advanced cardiac life support tools arrive swiftly to take over from bystanders, stabilizing patients for hospital transport.

Government and Community Support

The success of Victoria’s cardiac arrest response system is no accident—it results from dedicated efforts by healthcare professionals, government initiatives, and community involvement.

Government Initiatives

Victoria’s Ambulance Services Minister, Mary-Anne Thomas, commended the proactive approach taken by both professionals and community members. She emphasized the importance of immediate CPR and defibrillation, stating that “minutes matter in cardiac arrests.” The state government has continued to fund public access defibrillators and promote CPR training programs.

Community Training Programs

Recognizing the impact of bystander intervention, Victoria has prioritized CPR training in schools, workplaces, and community centers. These programs empower ordinary citizens with the skills to respond effectively during emergencies.

The Global Perspective on Cardiac Arrest Survival

While Victoria’s cardiac arrest survival rates are impressive, other leading regions like King County (U.S.) and Denmark have also demonstrated remarkable success. These areas share common strategies, including:

  • Mandatory CPR training in schools.
  • Publicly funded AED programs.
  • Widespread awareness campaigns on cardiac arrest response.
  • Highly efficient emergency medical services.

Looking Ahead: The Future of Cardiac Arrest Response in Victoria

Despite the achievements, there is still room for improvement. Experts suggest further increasing the number of AEDs in public places, expanding CPR education, and enhancing technology-driven emergency response systems.

Dr. Ziad Nehme, Ambulance Victoria’s Director of Research and Evaluation, emphasized that continued efforts in community engagement and innovation are necessary to maintain and improve survival rates.

Victoria’s remarkable success in improving cardiac arrest survival rates underscores the importance of early intervention, widespread CPR training, accessible defibrillators, and innovative technology like the GoodSAM app. By maintaining and enhancing these initiatives, the state sets a model for the rest of the world in tackling sudden cardiac arrest emergencies effectively.

As survival rates continue to improve, the message remains clear: immediate CPR and defibrillation save lives. Communities, healthcare professionals, and policymakers must continue working together to ensure that more people like Austin Blight have a fighting chance at survival.
