To the Editor: Over 26000 Australians experience out‐of‐hospital cardiac arrest (OHCA) each year, with almost nine in ten of these patients not surviving to hospital discharge or 30 days.1 Although it is known that swift defibrillation increases the possibility of patient survival in these situations, and that initial defibrillation by first responders (regardless of training) is associated with greater survival than initial defibrillation by emergency medical services,2 in Australia, less than 2% of OHCA cases receive defibrillation by a bystander.1 It is likely that this is driven by the limits to publicly accessible automated external defibrillators (AEDs) in Australian communities.3 On 30 November 2022, South Australia took a major step to deal with this problem and reduce death from OHCA. The SA Parliament passed the Automated External Defibrillators (Public Access) Bill 2022,4 making SA the first state or territory in Australia, and one of few in the world, to mandate the public provision of AEDs. The legislation, introduced by Member of the Legislative Council, the Hon Frank Pangallo of the SA‐BEST party, had bipartisan political support and backing from various organisations, and follows a recent public health campaign to install AEDs in Adelaide. The Bill will come into effect for government and public buildings in 2025 and a variety of private buildings in 2026, with awareness campaigns, grant programs, and communication with organisations being the focus of the interim period. The expected cost to the SA government of $7.2 million across four years is weighed against the $2 billion gross domestic product loss that Australia incurs annually as a result of sudden cardiac arrest.5 The health and economic benefits of public access defibrillation to Australian society are large. For the benefit of all Australians, other states and territories should follow the example set by SA and move to implement similar laws mandating the public availability of AEDs in their communities.

To the Editor: We applaud the authors for comparing ambulance offload times with mortality and re‐presentation rates for patients presenting with chest pain.1 However, the model employed by the authors fails to account for the independent impacts of access block and emergency department (ED) overcrowding on poor outcomes and thus risks overemphasising the influence of ramping. There is clear evidence that ED overcrowding and access block are associated with worse patient outcomes, including increased mortality, re‐presentation rates and ambulance offload times.2,3,4,5 This could explain many of the study's findings: ramping is the symptom, ED overcrowding and access block are the disease. Secondly, there are fundamental differences between tertiles 1 and 3 that have not been addressed. The patients in tertile 1 are more likely to have been offloaded straight into the waiting room, a common procedure in most EDs, whereas patients in tertile 3 would not, potentially due to poor mobility, dementia, or being assessed as requiring significant cardiorespiratory monitoring. For this reason, patients in tertile 1 would be expected to have better outcomes than those in tertile 3. The article adjusts for the presence of eight comorbid conditions but not their severity. Furthermore, the incidence of each individual comorbid condition was marginally higher in tertile 3, and although individually not statistically significant, the cumulative impact of multiple comorbid conditions would be higher in tertile 3, which could confound the results. The study's use of the Charlson index is limited, as it only uses the identified eight comorbid conditions. The Charlson index also includes dementia, hemiplegia, heart failure, liver disease, and cancer; these are not measured in the study and would all contribute to offload delays and worsened outcomes. Lastly, without including patients presenting via private transport with chest pain, and in the absence of any measures of ED overcrowding and access block, the analysis of patients presenting with chest pain remains incomplete. That ED overcrowding and access block, evidenced by ambulance offload delays, is associated with worsened outcomes is well known. Unfortunately, focusing on the symptom of ambulance ramping, rather than the disease of ED overcrowding and access block, risks leading to ill‐informed policy decisions and ineffective solutions.
