Objectives: Some geographic regions in high-income countries (HIC), including Australia, have poor healthy food access and a high burden of diet-related chronic disease. Scalable and sustainable strategies to strengthen community food systems have the potential to address these inequities. To inform future interventions in regions with poor healthy food access in Sydney, Australia, and beyond, we systematically reviewed randomised controlled trials of community-based food access interventions in HIC, to identify effects on dietary behaviours and health outcomes.

Methods: Four electronic databases were searched. Studies involving community-based healthy food access strategies (solely or combined with education/behaviour change) and measuring effects on dietary behaviours and/or health outcomes were identified. Data on dietary behaviours, health outcomes and intervention descriptions were extracted, and the risk of bias was assessed.

Results: Seven studies met inclusion criteria, with most conducted in the US (n = 6). Intervention strategies included food pantry-based interventions (n = 2), mobile produce markets (n = 2) and community farms (n = 3). Most interventions (n = 6, 85%) incorporated educational and/or behavioural change aspects. All studies measured fruit and vegetable (F&V) intake, with nearly all (n =6, 85%) reporting significant beneficial effects.

Conclusion: Preliminary evidence in our synthesis demonstrates that multicomponent community-based food system interventions promise to improve F&V intake in regions of HICs. Recommendations for improving future evaluations are identified to build evidence for policymakers and urban planners to enact upstream and downstream strategies to strengthen community healthy food, particularly in geographic regions with the greatest health inequities.

Objectives: Understanding and responding to emergency department (ED) presentations for suicide and self-harm is a major health system priority. Reporting using routinely collected ED diagnoses or presenting problem codes leads to significant underestimation of rates. We aimed to implement an enhanced method for reporting ED self-harm presentations in New South Wales (NSW), Australia.

Methods: An enhanced method was developed based on a literature review and clinical consultation. For NSW ED data collection records from 2005-2020, presenting problem codes were mapped to International Classification of Diseases version 10 (ICD-10). Self-harm codes (ICD-10 X60-84, Y87.0) were combined with additional codes for poisoning with medications commonly used in overdose and automated keyword searching of presenting problem text. Enhanced ED diagnoses were validated against hospital diagnoses for presentations resulting in hospital admission.

Results & discussion: Core ICD-10 self-harm codes identified 21 797 suicide and self-harm-related presentations per year to NSW EDs, of which 79% were for suicide-related ideation (R45.81). The enhanced method increased estimated annual presentations to 51 822 and increased sensitivity for suicide-related behaviours from 12.2% to 73.9%, while retaining high specificity (99.4%). Results matched known demographics of ED self-harm, and revised estimates were consistent with population rates reported by other jurisdictions. Service feedback and data sharing during the coronavirus disease 2019 (COVID-19) pandemic suggest that estimates from the enhanced method are plausible and sensitive to change.

Conclusions: In NSW ED data, standard presenting problem codes recorded by clinicians detect less than half of presentations for self-harm or suicidal ideas. An enhanced method using additional codes and free text searching is computationally simple and increases sensitivity for monitoring trends and service performance. The method will continue to be refined as new data items become available.

Objective: Due to the negative connotations around radiation, there is a great deal of angst in the community regarding radiation exposure and health; especially electromagnetic radiation (EMR) sources such as powerlines, mobile phone towers and the rollout of the 5G network. As such, it is important for health authorities to provide the public with information and assurances regarding radiation safety. The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) set up community engagement programs to address community concerns. Type of program or service: From 2003 until April 2022, ARPANSA operated a Health Complaints Register, which collected reports of health complaints from members of the public related to possible EMR exposures.

Methods: Collected data was used to produce annual statistical summaries on the nature and level of complaints received. Since 2016, ARPANSA has also run the Talk to a Scientist program, which allows the public to communicate directly with scientists on issues about radiation exposure, health and protection in Australia. Data is collected on the type of radiation and radiation source.

Results: There was a low level of interest in the Register, with only 180 reports received over the duration of its operation. Smart meters were the most common source of EMR exposure reported to be responsible for adverse health effects. The most common adverse health effect reported was headaches. The Register was closed in April 2022 due to a lack of interest. In contrast, the Talk to a Scientist program has responded to 6546 enquiries since 2016, most of which have been on EMR sources and the success of the Talk to a Scientist program, which rendered the Register obsolete.

Lessons learnt: The EMR Health Complaints Register never received much interest from the public, potentially due to a perceived lack of engagement with authorities. The Talk to a Scientist program, which facilitated direct interaction with subject matter experts, has been much more successful in engaging with the public and addressing community concerns on radiation safety.

Objectives and importance of study: Being physically active is critical for healthy ageing, yet many older people do not meet physical activity guidelines. The aim of this study was to test the relative effectiveness of five previously identified campaign slogans designed to encourage older people to be more physically active: 'Be active 30-60 minutes a day to stay fit and well'; 'Move more, live longer'; 'Stay fit to stay functional'; 'This is your time - enjoy being strong and active'; and 'Use it or lose it'.

Study type: Online experiment Methods: A total of 1200 Australians aged 50 years and older (50% female, mean age 65 years) were recruited to complete an online survey, with respondents randomised to answer a series of questions on a video featuring one of the five slogan conditions. One-way ANOVAs with Tukey's post-hoc tests were used to identify differences in outcomes between slogans.

Results: Overall, the slogans were assessed favourably, suggesting older adults may be receptive to messages about increasing their physical activity. 'Use it or lose it 'performed best across the outcome measures of internal and external motivation, perceived effectiveness, liking, believability, and personal relevance.

Conclusion: Efforts to encourage physical activity among older Australians could use the slogan 'Use it or lose it' as an evidence-based tagline.

Objectives: This paper reports on a program of research funded by a National Health and Medical Research Council (NHRMC) partnership grant (2015-2021) entitled "Delivering safe and effective test result communication, management and follow-up". The project's objectives were to: 1) improve the effectiveness and safety of test-result management through the establishment of clear governance processes of communication, responsibility, and accountability; 2) harness health information technology to inform and monitor test-result management; and 3) enhance consumer contribution to the establishment of safe and effective test-result management systems. Type of program: The partnership project addressed its key objectives through: i) the development of a consumer-driven approach; ii) using diagnostic stewardship and digital health to enhance safety and quality; iii) identifying clinical workflows that can lead to timely and meaningful communication; and iv) contributing to the Royal College of Pathologists of Australasia and Australasian Association for Clinical Biochemistry and Laboratory Medicine's work on nationally harmonised alert thresholds for critical laboratory results.

Methods: The project employed a convergent mixed-methods approach using multistage studies across hospitals in South Eastern Sydney and Illawarra and Shoalhaven Local Health Districts. A consumer-centred approach, including patient reference groups and community forums, was used to identify mechanisms to enhance consumers' role in test-management governance processes and inform the direction of the research and interpretation of findings. Results and lessons learnt: The body of evidence generated by the project highlights the multilayered and interconnected components required to achieve safe and effective test results management. Addressing the significant patient safety risk associated with the failure to follow-up test results must include consideration of diagnostic clinical work tasks (involving multiple people across numerous clinical settings) and embrace patient-centred and digital health strategies for shared information and timely and meaningful communication.

Objectives: This study was aimed at understanding the attitudes and positions of key Australian organisational and political stakeholders towards using psychedelic agents in medically supervised environments to treat mental health conditions. Specifically, this research was designed to identify some of the issues that might impede the clinical implementation of psychedelics.

Methods: Semi-structured interviews were conducted with four Australian politicians and nine representatives of key stakeholder organisations between September 2022 and January 2023. Data analyses were completed using pattern-based inductive thematic analysis.

Results: Participants were cautiously optimistic about using psychedelics to treat mental health conditions, with hesitancy emerging due to the perceived inadequacy of research into the efficacy and feasibility of these treatments. Politicians consistently mentioned that negative stigma prevented them and their peers from supporting the use of psychedelics in Australia. Effective, evidence-based, clear messaging that refutes misconceptions, uses persuasive messaging and provides clear information to inform implementation is needed to improve knowledge and challenge attitudes, biases and emotions that can influence the debate around psychedelics.

Conclusions: Stakeholder representatives and politicians agree that insufficient evidence exists to support the widespread clinical implementation of psychedelics in Australia. Politicians also perceive the stigma associated with psychedelics might negatively influence progressive legislation. Additional research and a clear presentation of this research are needed before the clinical use of psychedelics can be supported.

The emergency phase of the coronavirus disease 2019 (COVID-19) pandemic is over. Still, the work goes on in understanding the SARS-CoV-2 virus and its evolution, infection impacts - acute and long term - as well as therapeutics and the lessons for preventing and responding to future pandemics. Research into the long-term post-infection effects and therapeutic interventions also expands as the post-infection period lengthens. We provide an overview of the leading edge of COVID-19 research across clinical, epidemiological and social domains.

Loneliness and social isolation have been identified as critical global health issues in the aftermath of the coronavirus disease 2019 (COVID-19) crisis. While there is robust scientific evidence demonstrating the impact of loneliness and social isolation on health outcomes and mortality, there are fundamental issues to resolve so that health authorities, decision makers, and practitioners worldwide are informed and aligned with the latest evidence. Three priority actions are posited to achieve a wider and more substantial impact on loneliness and social isolation. They are 1) strengthening the evidence base; 2) adopting a whole-of-systems approach; 3) developing policy support for governments worldwide. These priority actions are essential to reduce the pervasive impact of loneliness and social isolation as social determinants of health.
