Implementing decision aids for cardiovascular disease prevention: stakeholder interviews and case studies in Australian primary care.

BACKGROUND: Australian cardiovascular disease (CVD) prevention guidelines recommend absolute CVD risk assessment, but less than half of eligible patients have the required risk factors recorded due to fragmented implementation over the last decade. Co-designed decision aids for general practitioners (GPs) and consumers have been developed that improve knowledge barriers to guideline-recommended CVD risk assessment and management. This study used a stakeholder consultation process to identify and pilot test the feasibility of implementation strategies for these decision aids in Australian primary care. METHODS: This mixed methods study included: (1) stakeholder consultation to map existing implementation strategies (2018-20); (2) interviews with 29 Primary Health Network (PHN) staff from all Australian states and territories to identify new implementation opportunities (2021); (3) pilot testing the feasibility of low, medium, and high resource implementation strategies (2019-21). Framework Analysis was used for qualitative data and Google analytics provided decision support usage data over time. RESULTS: Informal stakeholder discussions indicated a need to partner with existing programs delivered by the Heart Foundation and PHNs. PHN interviews identified the importance of linking decision aids with GP education resources, quality improvement activities, and consumer-focused prevention programs. Participants highlighted the importance of integration with general practice processes, such as business models, workflows, medical records and clinical audit software. Specific implementation strategies were identified as feasible to pilot during COVID-19: (1) low resource: adding website links to local health area guidelines for clinicians and a Heart Foundation toolkit for primary care providers; (2) medium resource: presenting at GP education conferences and integrating the resources into audit and feedback reports; (3) high resource: auto-populate the risk assessment and decision aids from patient records via clinical audit software. CONCLUSIONS: This research identified a wide range of feasible strategies to implement decision aids for CVD risk assessment and management. The findings will inform the translation of new CVD guidelines in primary care. Future research will use economic evaluation to explore the added value of higher versus lower resource implementation strategies.

Selfie-Related Incidents: Narrative Review and Media Content Analysis.

BACKGROUND: Selfie-related injury has become a public health concern amid the near ubiquitous use of smartphones and social media apps. Of particular concern are selfie-related deaths at aquatic locations; areas often frequented because of their photogenic allure. Unfortunately, such places exhibit hazards inherent with their environment. OBJECTIVE: This study aimed to ascertain current evidence regarding selfie-related injuries and recommended risk treatment measures in the academic literature as well as how selfie-related injuries and deaths were being reported by the media, allowing us to identify key challenges facing land managers and public health practitioners in mitigating selfie-related injuries and deaths. METHODS: Between October and December 2022, we performed a narrative review of peer-reviewed literature published since January 2011. Literature was screened to identify causal factors implicated in selfie-related deaths and injuries, as well as risk treatments recommended. Furthermore, we used an environmental scan methodology to search for media reports of selfie-related injuries and deaths at aquatic locations in Australia and the United States. Individual cases of selfie-related aquatic injuries and deaths sourced from news reports were analyzed to assess epidemiological characteristics, and a thematic content analysis was conducted to identify key themes of news reporting on selfie-related deaths and injuries. RESULTS: In total, 5 peer-reviewed studies were included. Four studies identified falls from height as the most common injury mechanism in selfie incidents. Drowning was the second most common cause of death. Recommended risk treatments were limited but included the adoption of "no selfie zones," physical barriers, signage, and provision of information on dangerous locations to social media users. In total, 12 cases were identified from media reports (4 injuries and 8 fatalities; 7 in Australia and 5 in the United States). The mean age of the reported victims was 22.1 (SD 6.93) years with victims more likely to be female tourists. Content analysis revealed 3 key themes from media reports: "blame," "warning," and "prevention and education." Few media reports (n=8) provided safety recommendations. CONCLUSIONS: The selfie-related incident phenomenon should be viewed as a public health problem that requires a public health risk communication response. To date, little attention has been paid to averting selfie-related incidents through behavior change methodologies or direct messaging to users, including through social media apps. Although previous research has recommended "no selfie zones," barriers, and signage as ways to prevent selfie incidents, our results suggest this may not be enough, and it may be prudent to also engage in direct safety messaging to social media users. Media reporting of selfie incidents should focus on preventive messaging rather than blame or warning.

'I actually thought that I was going to die': Lessons on the rip current hazard from survivor experiences.

BACKGROUND: Rip currents are strong, narrow, fast-flowing currents of water that occur on many beaches and in Australia contributing to 26 drowning deaths and several thousand lifeguard/lifesaver rescues each year. Educating the public about the rip current hazard is a primary focus of beach safety practitioners, but there has been a lack of qualitative research exploring the firsthand experiences of being caught in a rip current to assist in this regard. The aim of this study was to analyse interviews of rip current survivors to understand more about how people react when unintentionally caught in a rip current in order to help guide future public education to mitigate rip current drowning. METHODS: Semi-structured interviews were conducted with 56 individuals (primarily Australian-born) about their experience of being caught in a rip current. Interviewees were recruited via an online survey and varied in age and self-reported swimming ability. RESULTS: Thematic analysis revealed three key temporal elements to the rip current experience: Before the Rip in which lack of awareness and knowledge, complacency, over-confidence, and attitude were prevalent themes; During the Rip which identified panic and temporary inhibition of decision-making, physical response, prior experience, and relationships with other beach users as themes; and After the Rip where post-rip effects and rip safety messaging and education were key themes. The importance of experiential immersion was a prevalent thread throughout all phases of the thematic analysis. DISCUSSION: Our research shows that being caught in a rip current can be an intense and traumatic experience and that lessons learned from survivors have significant implications for improving existing and future rip current education efforts. In this regard, we provide several recommendations based on evidence-based insights gained from our interviews including the development of immersive rip current experience using virtual reality. SO WHAT: Despite the prevalence of rip currents causing drowning deaths and rescues, there has been a lack of qualitative research on firsthand experiences to aid in public education. These interviews emphasise the intense and traumatic nature of being caught in a rip current, underscoring the need for improved rip current education to aid in prevention of this, often harrowing, experience.

Preventing selfie-related incidents: Taking a public health approach to reduce unnecessary burden on emergency medicine services.

Unintentional deaths from selfies have received limited exposure in emergency medicine literature; yet trauma remains the leading cause of death and disability in children and young adults, and most of those implicated in a selfie incident are in this demographic. Selfie-related injuries and deaths may be a relatively new phenomenon, but data suggest they are a public health hazard that is not going away. Emergency medicine practitioners may have a role to play in the primary and secondary prevention of selfie incidents, including delivering opportunistic behaviour change messaging to those who are at risk of being injured or killed in a selfie-related incident, particularly young (14-25 years) males. Emergency medicine specialists should be aware of the dangers of selfie-related incidents and understand their polytraumatic presentation.

Addressing Behavioral Barriers to COVID-19 Testing With Health Literacy-Sensitive eHealth Interventions: Results From 2 National Surveys and 2 Randomized Experiments.

BACKGROUND: Polymerase chain reaction (PCR) testing for COVID-19 was crucial in Australia's prevention strategy in the first 2 years of the pandemic, including required testing for symptoms, contact with cases, travel, and certain professions. However, several months into the pandemic, half of Australians were still not getting tested for respiratory symptoms, and little was known about the drivers of and barriers to COVID-19 PCR testing as a novel behavior at that time. OBJECTIVE: We aimed to identify and address COVID-19 testing barriers, and test the effectiveness of multiple eHealth interventions on knowledge for people with varying health literacy levels. METHODS: The intervention was developed in 4 phases. Phase 1 was a national survey conducted in June 2020 (n=1369), in which testing barriers were coded using the capability-opportunity-motivation-behavior framework. Phase 2 was a national survey conducted in November 2020 (n=2034) to estimate the prevalence of testing barriers and health literacy disparities. Phase 3 was a randomized experiment testing health literacy-sensitive written information for a wide range of barriers between February and March 2021 (n=1314), in which participants chose their top 3 barriers to testing to view a tailored intervention. Phase 4 was a randomized experiment testing 2 audio-visual interventions addressing common testing barriers for people with lower health literacy in November 2021, targeting young adults as a key group endorsing misinformation (n=1527). RESULTS: In phase 1, barriers were identified in all 3 categories: capability (eg, understanding which symptoms to test for), opportunity (eg, not being able to access a PCR test), and motivation (eg, not believing the symptoms are those of COVID-19). Phase 2 identified knowledge gaps for people with lower versus higher health literacy. Phase 3 found no differences between the intervention (health literacy-sensitive text for top 3 barriers) and control groups. Phase 4 showed that a fact-based animation or a TikTok-style video presenting the same facts in a humorous style increased knowledge about COVID-19 testing compared with government information. However, no differences were found for COVID-19 testing intentions. CONCLUSIONS: This study identified a wide range of barriers to a novel testing behavior, PCR testing for COVID-19. These barriers were prevalent even in a health system where COVID-19 testing was free and widely available. We showed that key capability barriers, such as knowledge gaps, can be improved with simple videos targeting people with lower health literacy. Additional behavior change strategies are required to address motivational issues to support testing uptake. Future research will explore health literacy strategies in the current context of self-administered rapid antigen tests. The findings may inform planning for future COVID-19 variant outbreaks and new public health emergencies where novel testing behaviors are required.

Implementing patient decision aids into general practice clinical decision support systems: Feasibility study in cardiovascular disease prevention.

Objective: Patient decision aids (DA) facilitate shared decision making, but implementation remains a challenge. This study tested the feasibility of integrating a cardiovascular disease (CVD) prevention DA into general practice software. Methods: We developed a desktop computer application (app) to auto-populate a CVD prevention DA from general practice medical records. 4 practices received monthly practice reports from July-Nov 2021, and 2 practices use the app with limited engagement. CVD risk assessment data and app use were monitored. Results: The proportion of eligible patients with complete CVD risk assessment data ranged from 59 to 94%. Monthly app use ranged from 0 to 285 sessions by 13 individual practice staff including GPs and nurses, with staff using the app an average of 67 sessions during the study period. High users in the 5-month study period continued to use the app for 10 months. Low use was attributed to reduced staff capacity during COVID-19 and technical issues. Conclusion: High users sustained interest in the app, but additional strategies are required for low users. The study will inform implementation plans for new guidelines. Innovation: This study showed it is feasible to integrate patient decision aids with Australian general practice software, despite the challenges of COVID-19 at the time of the study.

Collateral positives of COVID-19 for culturally and linguistically diverse communities in Western Sydney, Australia.

BACKGROUND: To investigate whether culturally and linguistically diverse (CALD) communities in Western Sydney have experienced any positive effects during the COVID-19 pandemic, and if so, what these were. METHODS: A cross-sectional survey with ten language groups was conducted from 21st March to 9th July 2021 in Sydney, Australia. Participants were recruited through bilingual multicultural health staff and health care interpreter service staff and answered a question, 'In your life, have you experienced any positive effects from the COVID-19 pandemic?' Differences were explored by demographic variables. Free-text responses were thematically coded using the Content Analysis method. RESULTS: 707 people completed the survey, aged 18 to >70, 49% males and 51% females. Only 161 (23%) of those surveyed reported any positive impacts. There were significant differences in the proportion of those who reported positives based on age (p = 0.004), gender (p = 0.013), language (p = 0.003), health literacy (p = 0.014), English language proficiency (p = 0.003), education (p = <0.001) and whether participants had children less than 18 years at home (p = 0.001). Content Analysis of open-ended responses showed that, of those that did report positives, the top themes were 'Family time' (44%), 'Improved self-care' (31%) and, 'Greater connection with others' (17%). DISCUSSION: Few surveyed participants reported finding any positives stemming from the COVID-19 pandemic. This finding is in stark contrast to related research in Australia with participants whose native language is English in which many more people experienced positives. The needs of people from CALD backgrounds must inform future responses to community crises to facilitate an equitable effect of any collateral positives that may arise.

Decision Support Tools for Coronary Artery Calcium Scoring in the Primary Prevention of Cardiovascular Disease Do Not Meet Health Literacy Needs: A Systematic Environmental Scan and Evaluation.

A shared decision-making approach is considered optimal in primary cardiovascular disease (CVD) prevention. Evidence-based patient decision aids can facilitate this but do not always meet patients' health literacy needs. Coronary artery calcium (CAC) scans are increasingly used in addition to traditional cardiovascular risk scores, but the availability of high-quality decision aids to support shared decision-making is unknown. We used an environmental scan methodology to review decision support for CAC scans and assess their suitability for patients with varying health literacy. We systematically searched for freely available web-based decision support tools that included information about CAC scans for primary CVD prevention and were aimed at the public. Eligible materials were independently evaluated using validated tools to assess qualification as a decision aid, understandability, actionability, and readability. We identified 13 eligible materials. Of those, only one qualified as a decision aid, and one item presented quantitative information about the potential harms of CAC scans. None presented quantitative information about both benefits and harms of CAC scans. Mean understandability was 68%, and actionability was 48%. Mean readability (12.8) was much higher than the recommended grade 8 level. Terms used for CAC scans were highly variable. Current materials available to people considering a CAC scan do not meet the criteria to enable informed decision-making, nor do they meet the health literacy needs of the general population. Clinical guidelines, including CAC scans for primary prevention, must be supported by best practice decision aids to support decision-making.

The role of Primary Health Networks in cardiovascular disease prevention: A qualitative interview study.

BACKGROUND: Since the inception of PHNs in Australia, their role in implementing chronic disease prevention activities in general practice has been unclear. This study aimed to qualitatively explore the views of PHN staff on the role of PHNs in promoting prevention, with a focus on cardiovascular disease (CVD) prevention. METHODS: Content analysis of PHN Needs Assessments was conducted to inform interview questions. Twenty-nine semi-structured interviews were conducted with 32 PHN staff, between June and December 2020, in varied roles across 18 PHNs in all Australian states and territories. Transcribed audio recordings were thematically coded, using the Framework Analysis method to ensure rigour. RESULTS: We identified three main themes: (a) Informal prevention: All respondents agreed the role of PHNs in prevention was indirect and, for the most part, outside the formal remit of PHN Key Performance Indicators (KPIs.) Prevention activities were conducted in partnership with external stakeholders, professional development and quality improvement programs, and PHN-funded data extraction and analysis software for general practice. (b) Constrained by financial incentives: Most interviewees felt the role of PHNs in prevention was contingent on the financial drivers provided by the Commonwealth government, such as Medicare funding and national quality improvement programs. (c) Shaped through competing priorities: The role of PHNs in prevention is a function of competing priorities. There was strong agreement amongst participants that the myriad competing priorities from government and local needs assessments impeded prevention activities. CONCLUSIONS: PHNs are well-positioned to foster prevention activities in general practice. However, we found that PHNs role in prevention activities was informal, constrained by financial incentives and shaped through competing priorities. Prevention can be improved through a more explicit prevention focus at the Commonwealth government level. To optimise the role of PHNs, therefore, requires prioritising prevention, aligning it with KPIs and supporting stakeholders like general practice.

Positive outcomes associated with the COVID-19 pandemic in Australia.

ISSUE ADDRESSED: To investigate whether Australians have experienced any positive effects during the COVID-19 pandemic. METHODS: National online longitudinal survey. As part of a June 2020 survey, participants (n = 1370) were asked 'In your life, have you experienced any positive effects from the COVID-19 pandemic' (yes/no) and also completed the World Health Organisation-Five well-being index. Differences were explored by demographic variables. Free-text responses were thematically coded. RESULTS: Nine hundred sixty participants (70%) reported experiencing at least one positive effect during the COVID-19 pandemic. Living with others (P = .045) and employment situation (P < .001) at baseline (April) were associated with experiencing positive effects. Individuals working for pay from home were more likely to experience positive effects compared to those who were not working for pay (aOR = 0.45, 95% CI: 0.32, 0.63, P < .001) or who were working for pay outside the home (aOR = 0.40, 95% CI: 0.28, 0.58, P < .001). 54.2% of participants reported a sufficient level of well-being, 23.2% low well-being and a further 22.6% very low well-being. Of those experiencing positive effects, 945/960 (98%) provided an explanation. The three most common themes were 'Family time' (33%), 'Work flexibility' (29%) and 'Calmer life' (19%). CONCLUSIONS: A large proportion of participants reported positive effects resulting from changes to daily life due to the COVID-19 pandemic in Australia. SO WHAT: The needs of people living alone, and of those having to work outside the home or who are unemployed, should be considered by health policymakers and employers in future pandemic preparedness efforts.

Perceived public health threat a key factor for willingness to get the COVID-19 vaccine in Australia.

BACKGROUND: Vaccination rollout against COVID-19 is underway across multiple countries worldwide. Although the vaccine is free, rollout might still be compromised by hesitancy or concerns about COVID-19 vaccines. METHODS: We conducted two online surveys of Australian adults in April (during national lockdown; convenience cross-sectional sample) and November (very few cases of COVID-19; nationally representative sample) 2020, prior to vaccine rollout. We asked about intentions to have a potential COVID-19 vaccine (If a COVID-19 vaccine becomes available, I will get it) and free-text responses (November only). RESULTS: After adjustment for differences in sample demographics, the estimated proportion agreeing to a COVID-19 vaccine if it became available in April (n = 1146) was 76.3%. In November (n = 1941) this was estimated at 71.5% of the sample; additional analyses identified that the variation was driven by differences in perceived public health threat between April and November. Across both surveys, female gender, being younger, having inadequate health literacy and lower education were associated with reluctance to be vaccinated against COVID-19. Lower perceived susceptibility to COVID-19, belief that data on the efficacy of vaccines is 'largely made up', having lower confidence in government, and lower perception of COVID-19 as a public health threat, were also associated with reluctance to be vaccinated against COVID-19. The top three reasons for agreeing to vaccinate (November only) were to protect myself and others, moral responsibility, and having no reason not to get it. For those who were indifferent or disagreeing to vaccinate, safety concerns were the top reason, followed by indecision and lack of trust in the vaccine respectively. CONCLUSIONS: These findings highlight some factors related to willingness to accept a COVID-19 vaccine prior to one being available in Australia. Now that the vaccine is being offered, this study identifies key issues that can inform public health messaging to address vaccine hesitancy.

Chronic pain and cardiovascular disease prevention in primary care: a review of Australian primary health network needs assessments.

Objective Chronic pain and cardiovascular disease (CVD) have a high disease burden. This research aimed to understand whether Australian primary health networks (PHNs) are recognising the need for the prevention of these conditions by investigating what local health and service issues have been identified. Methods Separate sets of needs assessments were analysed for chronic pain and CVD for all 31 PHNs using a document analysis approach. Framework analysis was undertaken to ascertain the types of health and service issues, prevention-related issues and supporting data sources identified, as well as to quantify the number of PHNs identifying these issues. Results Fewer PHNs identified health issues for chronic pain (n = 13) compared with CVD (n = 30), with the most common being disease prevalence and burden supported by National Health Survey data. Service issues were identified by fewer than half the PHNs (n = 13 for each disease), which were largely informed by stakeholder consultation and related to service integration, service accessibility and health professional training. Prevention-related issues were frequently identified for CVD (n = 26), but not chronic pain (n = 3). Conclusions This paper highlights the need for a greater focus on chronic pain- and CVD-related issues by PHNs. This could be supported nationally by recognising chronic pain and risk factors in national datasets and PHN performance frameworks, and locally via greater stakeholder consultation to inform PHN population health planning. What is known about the topic? Chronic pain and CVD are the two leading causes of total disease burden in Australia. PHNs are well positioned to address prevention locally through population health planning, supporting primary healthcare providers, health care integration and coordination and commissioning necessary services. What does this paper add? This paper highlights gaps in data availability, the proportion of PHNs identifying local service issues for both chronic pain and CVD and health- and prevention-related issues for chronic pain. What are the implications for practitioners? Although PHNs are constrained by government priorities and funding, greater stakeholder consultation is one potentially promising strategy to overcome local data gaps to identifying and prioritising chronic pain and CVD prevention.

Do hospital consent forms for cardiology procedures meet health literacy standards? Evaluation of understandability and readability.

OBJECTIVES: Consent forms that are difficult to understand may jeopardize informed consent. The aim of this study was to determine whether consent documents for cardiology-related procedures could be easily read and understood by patients with low health literacy. METHODS: All 37 cardiology-related consent forms with patient information material were retrieved from a publicly available suite of documents from one state in Australia. Two raters independently assessed documents and resolved discrepancies through discussion. Understandability was assessed using the Patient Education Materials Assessment Tool for Printed materials (PEMAT-P). Readability was assessed using the Gunning Fog Index, SMOG and Flesch Reading Ease formulas. Images were assessed using the 5C Image checklist. Results were analyzed descriptively. RESULTS: Only 1 of 37 forms met the general PEMAT-P threshold (70%) for being 'understandable'. The average readability score was high, requiring a grade 10-12 level of education to understand. Most images lacked useful captions, had low visual clarity, and were not purpose-designed for the material. CONCLUSIONS: The current format for cardiology consent forms does not meet recommended standards for understandability and readability. PRACTICE IMPLICATIONS: Development of consent forms would benefit from taking health literacy principles into account with patient input, and purpose-designed images should be included in all forms to reinforce text.

Interventions Using Heart Age for Cardiovascular Disease Risk Communication: Systematic Review of Psychological, Behavioral, and Clinical Effects.

BACKGROUND: Cardiovascular disease (CVD) risk communication is a challenge for clinical practice, where physicians find it difficult to explain the absolute risk of a CVD event to patients with varying health literacy. Converting the probability to heart age is increasingly used to promote lifestyle change, but a rapid review of biological age interventions found no clear evidence that they motivate behavior change. OBJECTIVE: In this review, we aim to identify the content and effects of heart age interventions. METHODS: We conducted a systematic review of studies presenting heart age interventions to adults for CVD risk communication in April 2020 (later updated in March 2021). The Johanna Briggs risk of bias assessment tool was applied to randomized studies. Behavior change techniques described in the intervention methods were coded. RESULTS: From a total of 7926 results, 16 eligible studies were identified; these included 5 randomized web-based experiments, 5 randomized clinical trials, 2 mixed methods studies with quantitative outcomes, and 4 studies with qualitative analysis. Direct comparisons between heart age and absolute risk in the 5 web-based experiments, comprising 5514 consumers, found that heart age increased positive or negative emotional responses (4/5 studies), increased risk perception (4/5 studies; but not necessarily more accurate) and recall (4/4 studies), reduced credibility (2/3 studies), and generally had no effect on lifestyle intentions (4/5 studies). One study compared heart age and absolute risk to fitness age and found reduced lifestyle intentions for fitness age. Heart age combined with additional strategies (eg, in-person or phone counseling) in applied settings for 9582 patients improved risk control (eg, reduced cholesterol levels and absolute risk) compared with usual care in most trials (4/5 studies) up to 1 year. However, clinical outcomes were no different when directly compared with absolute risk (1/1 study). Mixed methods studies identified consultation time and content as important outcomes in actual consultations using heart age tools. There were differences between people receiving an older heart age result and those receiving a younger or equal to current heart age result. The heart age interventions included a wide range of behavior change techniques, and conclusions were sometimes biased in favor of heart age with insufficient supporting evidence. The risk of bias assessment indicated issues with all randomized clinical trials. CONCLUSIONS: The findings of this review provide little evidence that heart age motivates lifestyle behavior change more than absolute risk, but either format can improve clinical outcomes when combined with other behavior change strategies. The label for the heart age concept can affect outcomes and should be pretested with the intended audience. Future research should consider consultation time and differentiate between results of older and younger heart age.

The Psychological Impact of Hypertension During COVID-19 Restrictions: Retrospective Case-Control Study.

BACKGROUND: It is unclear how people with hypertension are responding to the COVID-19 pandemic given their increased risk, and whether targeted public health strategies are needed. OBJECTIVE: This retrospective case-control study compared people with hypertension to matched healthy controls during the COVID-19 lockdown to determine whether they have higher risk perceptions, anxiety, and vaccination intentions. METHODS: Baseline data from a national survey were collected in April 2020 during the COVID-19 lockdown in Australia. People who reported hypertension with no other chronic conditions were randomly matched to healthy controls of similar age, gender, education, and health literacy level. A subset including participants with hypertension was followed up at 2 months after restrictions were eased. Risk perceptions, anxiety, and vaccination intentions were measured in April and June. RESULTS: Of the 4362 baseline participants, 466 (10.7%) reported hypertension with no other chronic conditions. A subset of 1369 people were followed up at 2 months, which included 147 (10.7%) participants with hypertension. At baseline, perceived seriousness was high for both hypertension and control groups. The hypertension group reported greater anxiety compared to the controls and were more willing to vaccinate against influenza, but COVID-19 vaccination intentions were similar. At follow-up, these differences were no longer present in the longitudinal subsample. Perceived seriousness and anxiety had decreased, but vaccination intentions for both influenza and COVID-19 remained high across groups (>80%). CONCLUSIONS: Anxiety was above normal levels during the COVID-19 lockdown. It was higher in the hypertension group, which also had higher vaccination intentions. Groups that are more vulnerable to COVID-19 may require targeted mental health screening during periods of greater risk. Despite a decrease in perceived risk and anxiety after 2 months of lockdown restrictions, vaccination intentions remained high, which is encouraging for the future prevention of COVID-19.

Contextualising COVID-19 prevention behaviour over time in Australia: Patterns and long-term predictors from April to July 2020 in an online social media sample.

BACKGROUND: In Australia in March 2020 a national public health directive required that non-essential workers stay at home, except for essential activities. These restrictions began easing in May 2020 as community transmission slowed. OBJECTIVES: This study investigated changes in COVID prevention behaviours from April-July 2020, and psychosocial predictors of these behaviours. METHODS: An Australia-wide (national) survey was conducted in April, with monthly follow-up over four months. Participants who were adults (18+ years), currently residing in Australia and who could read and understand English were eligible. Recruitment was via online social media. Analysis sample included those who provided responses to the baseline survey (April) and at least one subsequent follow-up survey (N = 1834 out of a possible 3216 who completed the April survey). 71.7% of the sample was female (n = 1,322). Principal components analysis (PCA) combined self-reported adherence across seven prevention behaviours. PCA identified two behaviour types: 'distancing' (e.g. staying 1.5m away) and 'hygiene' (e.g. washing hands), explaining 28.3% and 24.2% of variance, respectively. Distancing and hygiene behaviours were analysed individually using multivariable regression models. RESULTS: On average, participants agreed with statements of adherence for all behaviours (means all above 4 out of 7). Distancing behaviours declined each month (p's < .001), whereas hygiene behaviours remained relatively stable. For distancing, stronger perceptions of societal risk, self-efficacy to maintain distancing, and greater perceived social obligation at baseline were associated with adherence in June and July (p's<0.05). For hygiene, the only significant correlate of adherence in June and July was belief that one's actions could prevent infection of family members (p < .001). CONCLUSION: High adherence to COVID prevention behaviours were reported in this social media sample; however, distancing behaviours tended to decrease over time. Belief in social responsibility may be an important aspect to consider in encouraging distancing behaviours. These findings have implications for managing a shift from government-imposed restrictions to individual responsibility.

COVID-19 Misinformation Trends in Australia: Prospective Longitudinal National Survey.

BACKGROUND: Misinformation about COVID-19 is common and has been spreading rapidly across the globe through social media platforms and other information systems. Understanding what the public knows about COVID-19 and identifying beliefs based on misinformation can help shape effective public health communications to ensure efforts to reduce viral transmission are not undermined. OBJECTIVE: This study aimed to investigate the prevalence and factors associated with COVID-19 misinformation in Australia and their changes over time. METHODS: This prospective, longitudinal national survey was completed by adults (18 years and above) across April (n=4362), May (n=1882), and June (n=1369) 2020. RESULTS: Stronger agreement with misinformation was associated with younger age, male gender, lower education level, and language other than English spoken at home (P<.01 for all). After controlling for these variables, misinformation beliefs were significantly associated (P<.001) with lower levels of digital health literacy, perceived threat of COVID-19, confidence in government, and trust in scientific institutions. Analyses of specific government-identified misinformation revealed 3 clusters: prevention (associated with male gender and younger age), causation (associated with lower education level and greater social disadvantage), and cure (associated with younger age). Lower institutional trust and greater rejection of official government accounts were associated with stronger agreement with COVID-19 misinformation. CONCLUSIONS: The findings of this study highlight important gaps in communication effectiveness, which must be addressed to ensure effective COVID-19 prevention.

Health literacy and disparities in COVID-19-related knowledge, attitudes, beliefs and behaviours in Australia.

OBJECTIVES: To explore the variation in understanding of, attitudes towards, and uptake of, health advice on coronavirus disease 2019 (COVID-19) during the 2020 pandemic stage 3 restrictions ('lockdown') by health literacy in the Australian population. STUDY DESIGN: National cross-sectional community survey. SETTING: Australian general public. PARTICIPANTS: Adults aged over 18 years (N = 4362). MAIN OUTCOME MEASURES: Knowledge, attitudes and behaviours related to COVID-19; health literacy and sociodemographic factors. RESULTS: People with inadequate health literacy had poorer understanding of COVID-19 symptoms (49% vs 68%; p < 0.001), were less able to identify behaviours to prevent infection (59%% vs 72% p < 0.001), and experienced more difficulty finding information and understanding government messaging about COVID-19 than people with adequate health literacy. People with inadequate health literacy were less likely to rate social distancing as important (6.1 vs 6.5; p < 0.001) and reported more difficulty with remembering and accessing medicines since lockdown (3.6 vs 2.7; p < 0.001). People with lower health literacy were also more likely to endorse misinformed beliefs about COVID-19 and vaccinations (in general) than those with adequate health literacy. The same pattern of results was observed among people who primarily speak a language other than English at home. CONCLUSION: Our findings show that there are important disparities in COVID-19-related knowledge, attitudes and behaviours according to people's health literacy and language. These have the potential to undermine efforts to reduce viral transmission and may lead to social inequalities in health outcomes in Australia. People with the greatest burden of chronic disease are most disadvantaged, and are also most likely to experience severe disease and die from COVID-19. Addressing the health literacy, language and cultural needs of the community in public health messaging about COVID-19 must now be a priority in Australia.
