The influence of the COVID-19 pandemic on lung cancer surgery in Queensland.

BACKGROUND: The coronavirus disease-19 (COVID-19) pandemic poses unprecedented challenges to global healthcare. The contemporary influence of COVID-19 on the delivery of lung cancer surgery has not been examined in Queensland. METHODS: We performed a retrospective registry analysis of the Queensland Cardiac Outcomes Registry (QCOR), thoracic database examining all adult lung cancer resections across Queensland from 1/1/2016 to 30/4/2022. We compared the data prior to, and after, the introduction of COVID-restrictions. RESULTS: There were 1207 patients. Mean age at surgery was 66 years and 1115 (92%) lobectomies were performed. We demonstrated a significant delay from time of diagnosis to surgery from 80 to 96 days (P < 0.0005), after introducing COVID-restrictions. The number of surgeries performed per month decreased after the pandemic and has not recovered (P = 0.012). 2022 saw a sharp reduction in cases with 49 surgeries, compared to 71 in 2019 for the same period. CONCLUSION: Restrictions were associated with a significant increase in pathological upstaging, greatest immediately after the introduction of COVID-restrictions (IRR 1.71, CI 0.93-2.94, P = 0.05). COVID-19 delayed the access to surgery, reduced surgical capacity and consequently resulted in pathological upstaging throughout Queensland.

Decreased Neisseria gonorrhoeae genotypic diversity following COVID-19 restrictions in Queensland, Australia 2020.

We investigated the potential effects of COVID-19 public health restrictions on the prevalence and distribution of Neisseria gonorrhoeae (NG) genotypes in our Queensland isolate population in the first half of the year 2020. A total of 763 NG isolates were genotyped to examine gonococcal strain distribution and prevalence for the first 6 months of 2020, with 1 January 2020 to 31 March 2020 classified as 'pre' COVID-19 restrictions (n = 463) and 1 April 2020 to 30 June 2020 classified as 'post' COVID-19 restrictions (n = 300). Genotypes most prevalent 'pre' restrictions remained proportionally high 'post' restrictions, with some significantly increasing 'post' restrictions. However, genotype diversity was significantly reduced 'post' restrictions. Overall, it seems public health restrictions (9-10 weeks) were not sufficient to affect rates of infection or reduce the prevalence of well-established genotypes in our population, potentially due to reduced access to services or health-seeking behaviours.

Heatwaves and mortality in Queensland 2010-2019: implications for a homogenous state-wide approach.

Heatwaves are a significant cause of adverse health outcomes and mortality in Australia, worsening with climate change. In Queensland, the northeastern-most state, little is known about the impact of heatwaves outside of the capital city of Brisbane. This study aims to explore the impact of heatwaves on mortality across various demographic and environmental conditions within Queensland from 2010 to 2019. The Excess Heat Factor was used to indicate heatwave periods at the Statistical Area 2 (SA2) level. Registered deaths data from the Australian Bureau of Statistics and heatwave data from the Bureau of Meteorology were matched using a case-crossover approach. Relative risk and 95% confidence intervals were calculated across years, regions, age, sex, rurality, socioeconomic status, and cause of death. Heatwaves were associated with a 5% increase in all-cause mortality compared to deaths on non-heatwave days, with variability across the state. The risk of death on a heatwave day versus a non-heatwave day varied by heatwave severity. Individuals living in urban centers, the elderly, and those living in regions of lower socioeconomic status were most impacted by heatwave mortality. The relative risk of dying from neoplasms, nervous system conditions, respiratory conditions, and mental and behavioral conditions increased during heatwaves. As heatwaves increase in Queensland due to climate change, understanding the impact of heatwaves on mortality across Queensland is important to tailor public health messages. There is considerable variability across communities, demographic groups, and medical conditions, and as such messages need to be tailored to risk.

Wave of COVID-19 outbreaks in Gold Coast residential aged care facilities after easing travel restrictions into Queensland.

Objective: This paper describes outbreaks of coronavirus disease 2019 (COVID-19) in Gold Coast residential aged care facilities (RACFs), in the two months following the easing of travel restrictions at Queensland's domestic border on 13 December 2021. Methods: This audit reviewed all RACF COVID-19 outbreaks notified to the Gold Coast Public Health Unit between 13 December 2021 and 12 February 2022. An outbreak was defined by the Communicable Diseases Network Australia guidelines current at the time. Results: There were 60 COVID-19 outbreaks across 57 RACFs during this period. In 44 outbreaks (73.3%), a staff member was identified as the primary or co-primary case. Transmission amongst residents occurred in 48 outbreaks (80.0%). The attack rates in staff and residents were 17.0% (n = 1,060) and 11.7% (n = 645) respectively. A higher number of males were hospitalised (n = 39: 57.4%) or died (n = 28: 66.7%) than were females (n = 29: 42.6%; n = 14: 33.3% respectively). Most resident cases (n = 565: 87.6%) had received two or more doses of a COVID-19 vaccine. In resident cases who were under-vaccinated (n = 76), twenty (26.3%) required hospitalisation and nine (11.8%) died. In resident cases who received two doses of vaccine (n = 484), forty-three (8.9%) were hospitalised and 27 (5.8%) died. In resident cases who had received three doses (n = 80), four (5.0%) were hospitalised and five (6.3%) died. Conclusions: COVID-19 caused significant morbidity and mortality in Gold Coast RACFs following the easing of border restrictions. Higher rates of hospitalisation and death occurred in males than in females, and in under-vaccinated resident cases than in those vaccinated with at least two doses of a COVID-19 vaccine. Implications for public health: These data support the need for up-to-date COVID-19 vaccination of residents in RACFs, continued surveillance and timely and appropriate implementation of public health guidelines to manage COVID-19 outbreaks in RACFs.

Predicting mortality and admission duration for burns patients in Queensland, Australia: a retrospective cohort study.

BACKGROUND: Burn outcomes can be improved by reducing mortality and hospital admission duration. This increases patient quality of life and reduces hospital-associated complications and costs. This study aimed to develop a model with which to predict burns inpatient mortality and admission duration. METHODS: Multiple logistic and linear regression were used to investigate mortality and admission duration by age, total body surface area, sex, delay to presentation, the use of surgery, discharge distance and period. RESULTS: One thousand four hundred and seventy nine patients (747 pre-COVID and 732 during COVID) were admitted between the study dates. Using multiple logistic regression, age and total body surface area predicted mortality LR X2 (5), P < 0.001, pseudo R2  = 0.57. Using multiple linear regression, age, total body surface area and the use of surgery predicted admission duration F (7, 1455) = 161.42, P < 0.001, R2  = 0.44. Sex, delay to presentation, period and discharge distance did not predict mortality or admission duration. CONCLUSIONS: In our institution, mortality was increased by 8.6% for each additional year of age and by 11.3% for each additional percentage total body surface area. Likewise, admission duration was prolonged by 1 day for every 7 years of increased age, by 1 day for each additional percentage total body surface area or by 7 days if surgery was required. These models have been incorporated into a set of prediction tables for mortality and admission duration for use in our institute that can guide patient and family discussions.

Did the coronavirus vaccination program in a rural and regional area work? Health outcomes of the vaccination program in Wide Bay.

The objective of this case study is to evaluate the effectiveness of the Wide Bay region coronavirus vaccination program in preventing hospitalisation for coronavirus disease 2019 (COVID-19). Population vaccination data and the vaccination status of patients hospitalised with confirmed COVID-19 have been used to evaluate preventable hospitalisations and risk reduction during and after a 2 month period following the outbreak of COVID-19 in Wide Bay after removal of public health measures in Queensland in December 2021. Wide Bay is a rural region of Queensland including K'Gari (formerly Fraser Island) to the east, the North Burnett farming region in the west and extending from the Fraser Coast to the Discovery Coast. Two local regional hospitals received and managed hospitalised COVID-19 patients. The region had, at this time, 171 365 people 20 years and older eligible for coronavirus vaccination. The risk reduction for hospitalisation of those receiving fewer than two vaccinations, two vaccinations and three vaccinations was calculated to determine the vaccination program effectiveness. The program achieved 90% effectiveness for people with two or more vaccinations (those with two vaccinations and those receiving boosters of third or more vaccination), and 97% effectiveness for those having received three vaccinations, in preventing hospitalisation for COVID-19 during the period. This translated into a significant risk reduction for hospitalisation for those receiving two or more vaccinations, preserving capacity to enable the health service to manage all cases locally.

Occurrence of multiple respiratory viruses in wastewater in Queensland, Australia: Potential for community disease surveillance.

The early warning and tracking of COVID-19 prevalence in the community provided by wastewater surveillance has highlighted its potential for much broader viral disease surveillance. In this proof-of-concept study, 46 wastewater samples from four wastewater treatment plants (WWTPs) in Queensland, Australia, were analyzed for the presence and abundance of 13 respiratory viruses, and the results were compared with reported clinical cases. The viruses were concentrated using the adsorption-extraction (AE) method, and extracted nucleic acids were analyzed using qPCR and RT-qPCR. Among the viruses tested, bocavirus (BoV), parechovirus (PeV), rhinovirus A (RhV A) and rhinovirus B (RhV B) were detected in all wastewater samples. All the tested viruses except influenza B virus (IBV) were detected in wastewater sample from at least one WWTP. BoV was detected with the greatest concentration (4.96-7.22 log10 GC/L), followed by Epstein-Barr virus (EBV) (4.08-6.46 log10 GC/L), RhV A (3.95-5.63 log10 GC/L), RhV B (3.74-5.61 log10 GC/L), and PeV (3.17-5.32 log10 GC/L). Influenza viruses and respiratory syncytial virus (RSV) are notifiable conditions in Queensland, allowing the gene copy (GC) concentrations to be compared with reported clinical cases. Significant correlations (ρ = 0.60, p < 0.01 for IAV and ρ = 0.53, p < 0.01 for RSV) were observed when pooled wastewater influenza A virus (IAV) and RSV log10 GC/L concentrations were compared to log10 clinical cases among the four WWTP catchments. The positive predictive value for the presence of IAV and RSV in wastewater was 97 % for both IAV and RSV clinical cases within the four WWTP catchments. The overall accuracy of wastewater analysis for predicting clinical cases of IAV and RSV was 97 and 90 %, respectively. This paper lends credibility to the application of wastewater surveillance to monitor respiratory viruses of various genomic characteristics, with potential uses for increased surveillance capabilities and as a tool in understanding the dynamics of disease circulation in the communities.

Household transmission of the Delta COVID-19 variant in Queensland, Australia: a case series.

Household transmission plays a key role in the spread of COVID-19 through populations. In this paper, we report on the transmission of COVID-19 within households in a metropolitan area in Australia, examine the impact of various factors and highlight priority areas for future public health responses. We collected and reviewed retrospective case report data and follow-up interview responses from households with a positive case of the Delta COVID-19 variant in Queensland in 2021. The overall secondary attack rate (SAR) among household contacts was 29.6% and the mean incubation period for secondary cases was 4.3 days. SAR was higher where the index case was male (57.9% vs. 14.3%) or aged ≤12 years (38.7% vs. 17.4%) but similar for adult contacts that were double vaccinated (35.7%) and unvaccinated (33.3%). Most interview participants emphasised the importance of clear, consistent and compassionate health advice as a key priority for managing outbreaks in the home. The overall rate of household transmission was slightly higher than that reported in previous studies on the wild COVID-19 variant and secondary infections developed more rapidly. While vaccination did not appear to affect the risk of transmission to adult subjects, uptake in the sample was ultimately high.

Seeking to improve access to COVID-19 therapeutics in the remote Torres and Cape communities of Far North Queensland during the first COVID-19 omicron outbreak.

INTRODUCTION: The first outbreak of the omicron variant of COVID-19 in the Torres and Cape region of Far North Queensland in Australia was declared in late December 2021. A COVID-19 Care at Home program was created to support the health and non-health needs of people with COVID-19 and their families throughout the mandatory isolation periods and included centralising the coordination and delivery of COVID-19 therapeutics. The therapeutics available included one intravenous monoclonal antibody (sotrovimab) and two oral antiviral therapies: nirmatrelvir and ritonavir (Paxlovid®) and molnupiravir (Lagevrio®). This article describes the uptake and delivery of this therapeutics program. METHODS: COVID-19 cases were documented in a notification database, screened to determine eligibility for COVID-19 therapies and prioritised based on case age, vaccination status, immunosuppression status and existing comorbidities, in line with Queensland clinical guidelines. Eligible cases were individually contacted by phone to discuss treatment options, and administration of therapies were coordinated in partnership with local primary healthcare centres and hospitals. RESULTS: A total of 4744 cases were notified during the outbreak period, of which 217 (4.6%) were deemed eligible for treatment after medical review. Treatment was offered to 148/217 cases (68.2%), with 90/148 cases (60.8%) declining treatment and 53/148 cases (35.8%) receiving therapeutic treatment for COVID-19. Among these 53 cases, 29 received sotrovimab (54.7%), 20 received Paxlovid (37.7%) and four received Lagevrio (7.5%). First Nations people accounted for 48/53 cases (90.6%) who received treatment, and COVID-19 therapeutics were delivered to cases in 16 remote First Nations communities during the outbreak period. CONCLUSION: The COVID-19 Care at Home program demonstrated a novel, public health led approach to delivering time-critical medications to individuals across a large, remote and logistically complex region. The application of similar models to outbreaks and chronic conditions of public health importance offers potential to address many health access inequities experienced by remote Australian First Nations communities.

Protocol for a winter sentinel surveillance program of notifiable respiratory viruses in Queensland.

BACKGROUND: With the reduction in access to polymerase chain reaction (PCR) testing and changes in testing guidelines in Australia, a reduced number of people are seeking testing for coronavirus disease (COVID-19), limiting the opportunity to monitor disease transmission. Knowledge of community transmission of COVID-19 and other respiratory viruses is essential to better predict subsequent surges in cases during the pandemic to alert health services, protect vulnerable populations and enhance public health measures. We describe a methodology for a testing-based sentinel surveillance program to monitor disease in the community for early signal detection of SARS-CoV-2 and other respiratory viruses. METHODS/DESIGN: A longitudinal active testing-based sentinel surveillance program for respiratory viruses (including SARS-CoV-2, influenza A, influenza B and Respiratory Syncytial Virus) will be implemented in some regions of Queensland. Adults will be eligible for enrolment if they are part of specific community groups at increased risk of exposure and have not had a COVID-19 infection in the last 13 weeks. Recruitment via workplaces will occur in-person, via email and through online advertisement. Asymptomatic participants will be tested via PCR for SARS-CoV-2 infection by weekly self-collected nasal swabs. In addition, symptomatic participants will be asked to seek SARS-CoV-2 and additional respiratory virus PCR testing at nominated COVID-19 testing sites. SARS-CoV-2 and respiratory virus prevalence data will be analysed weekly and at the end of the study period. DISCUSSION: Once implemented, this surveillance program will determine the weekly prevalence of COVID-19 and other respiratory viruses in the broader community by testing a representative sample of adults, with an aim to detect early changes in the baseline positivity rate. This information is essential to define the epidemiology of SARS-CoV-2 in the community in near-real time to inform public health control measures and prepare health services and other stakeholders for a rise in service demand.

Post COVID-19 vaccination: AusVaxSafety survey participation and adverse events - a community-based regional Queensland study.

OBJECTIVE: To describe adverse events following COVID-19 immunisation (AEFI) and participation in AusVaxSafety surveillance in a Queensland regional community. METHODS: Participants presenting for second dose COVID-19 vaccine at the Hervey Bay Wide Bay Hospital and Health Service (WBHHS) vaccine clinic in July 2021 completed a survey pertaining to their first COVID-19 vaccine. Data collected included participation in AusVaxSafety surveillance, vaccine type (BNT162b2 (Pfizer/BioNTech) or ChAdOx1-S(Oxford/AstraZeneca), AEFI experienced and impact on work/routine activities. Multivariable logistic regression related demographic factors to odds of surveillance participation and AEFI occurrence. RESULTS: Of 1,148 participants, 37.6% participated in AusVaxSafety surveillance and 44.8% reported an AEFI. Participation in surveillance was higher in older (≥50 vs <50 years: OR 1.36, 95%CI:1.04-1.78) and less-educated participants (university vs. high school/below: OR 0.68, 95%CI:0.48-0.95). Reporting an AEFI was higher in younger (≥50 years vs. <50 years: BNT162b2: OR 0.69, 95%CI:0.51-0.93; ChAdOx1-S: OR 0.42, 95%CI:0.10-1.89), female (female vs. male: BNT162b2: OR 2.28, 95%CI:1.67-3.12; ChAdOx1-S: OR 1.85, 95%CI:1.17-2.94) and more educated participants (university vs. high school/below: BNT162b2:OR 1.63, 95%CI: 1.08-2.45; ChAdOx1-S: OR 3.98, 95%CI:2.03-7.79). Of participants with an AEFI, 15% reported missing work/routine activities. CONCLUSIONS: Participation in surveillance was modest in this regional population, despite AEFI being frequent, and impacts of absenteeism in this setting warrants further research. IMPLICATIONS FOR PUBLIC HEALTH: The findings can inform strategies to improve surveillance participation and inform workforce planning in regional areas.

Modelling herd immunity requirements in Queensland: impact of vaccination effectiveness, hesitancy and variants of SARS-CoV-2.

Long-term control of SARS-CoV-2 outbreaks depends on the widespread coverage of effective vaccines. In Australia, two-dose vaccination coverage of above 90% of the adult population was achieved. However, between August 2020 and August 2021, hesitancy fluctuated dramatically. This raised the question of whether settings with low naturally derived immunity, such as Queensland where less than [Formula: see text] of the population is known to have been infected in 2020, could have achieved herd immunity against 2021's variants of concern. To address this question, we used the agent-based model Covasim. We simulated outbreak scenarios (with the Alpha, Delta and Omicron variants) and assumed ongoing interventions (testing, tracing, isolation and quarantine). We modelled vaccination using two approaches with different levels of realism. Hesitancy was modelled using Australian survey data. We found that with a vaccine effectiveness against infection of 80%, it was possible to control outbreaks of Alpha, but not Delta or Omicron. With 90% effectiveness, Delta outbreaks may have been preventable, but not Omicron outbreaks. We also estimated that a decrease in hesitancy from 20% to 14% reduced the number of infections, hospitalizations and deaths by over 30%. Overall, we demonstrate that while herd immunity may not be attainable, modest reductions in hesitancy and increases in vaccine uptake may greatly improve health outcomes. This article is part of the theme issue 'Technical challenges of modelling real-life epidemics and examples of overcoming these'.

Associations between COVID-19 lockdown and post-lockdown on the mental health of pregnant women, postpartum women and their partners from the Queensland family cohort prospective study.

BACKGROUND: There are very few developed countries where physical isolation and low community transmission has been reported for COVID-19 but this has been the experience of Australia. The impact of physical isolation combined with low disease transmission on the mental health of pregnant women is currently unknown and there have been no studies examining the psychological experience for partners of pregnant women during lockdown. The aim of the current study was to examine the impact of the first COVID-19 lockdown in March 2020 and post lockdown from August 2020 on the mental health of pregnant women or postpartum women and their partners. METHODS: Pregnant women and their partners were prospectively recruited to the study before 24 weeks gestation and completed various questionnaires related to mental health and general wellbeing at 24 weeks gestation and then again at 6 weeks postpartum. The Depression, Anxiety and Stress Scale (DASS-21) and the Edinburgh Postnatal Depression Scale (EPDS) were used as outcome measures for the assessment of mental health in women and DASS-21 was administered to their partners. This analysis encompasses 3 time points where families were recruited; before the pandemic (Aug 2018-Feb 2020), during lockdown (Mar-Aug 2020) and after the first lockdown was over (Sept-Dec 2020). RESULTS: There was no significant effect of COVID-19 lockdown and post lockdown on depression or postnatal depression in women when compared to a pre-COVID-19 subgroup. The odds of pregnant women or postpartum women experiencing severe anxiety was more than halved in women during lockdown relative to women in the pre-COVID-19 period (OR = 0.47; 95%CI: 0.27-0.81; P = 0.006). Following lockdown severe anxiety was comparable to the pre-COVID-19 women. Lockdown did not have any substantial effects on stress scores for pregnant and postpartum women. However, a substantial decrease of over 70% in the odds of severe stress was observed post-lockdown relative to pre-COVID-19 levels. Partner's depression, anxiety and stress did not change significantly with lockdown or post lockdown. CONCLUSION: A reproductive age population appear to be able to manage the impact of lockdown and the pandemic with some benefits related to reduced anxiety.

"Scary to get, more scary not to": COVID-19 vaccine acceptance among healthcare workers in Central Queensland, Australia, a cross-sectional survey.

Background: Behavioural and social drivers (BeSD) of coronavirus disease 2019 (COVID-19) vaccine acceptance among Australian healthcare workers (HCW) living and working in regional areas are not well studied. Understanding local HCWs' COVID-19 risk perceptions and potential barriers to COVID-19 vaccine uptake is crucial in supporting rollout. We aimed to understand the COVID-19 vaccine drivers among HCW in Central Queensland (CQ), Australia. Method: A cross-sectional online survey of HCWs in CQ between 17 May and 31 May 2021, based on the BeSD framework adapted from the World Health Organization (WHO) Data for Action guidance, consisting of the five instrument domains: what people think and feel; social processes; motivations; practical issues; and vaccination uptake. Results: Of the 240 responding HCWs within Central Queensland Hospital and Health Service, 78% were female. Of the participating HCWs, 64% percent had received at least one dose of a COVID-19 vaccine; of those who had not yet received a vaccine, 53% said they were willing to receive one. Factors associated with vaccine acceptance included: belief that the vaccine was important for their health (81%; odds ratio (OR): 7.2; 95% confidence interval (CI): 3.5-15.5); belief that their family and friends wanted them to have the vaccine (64%; OR: 6.7; 95% CI: 2.9-16.7); trust in the vaccine (72%; OR: 6.4; 95% CI: 3.5-12.0); and confidence in being able to answer patients' questions about the vaccine (99%). Conclusions: These findings suggest that a combination of communications and educational material framed around the benefits and social norms of vaccination, along with materials addressing vaccine safety concerns, will encourage HCW to take up a COVID-19 vaccine.

Two Treponema pallidum strains account for the majority of syphilis infections, including among females, in Queensland, Australia.

Abstract: An ongoing outbreak of syphilis in Australia, first reported in the state of Queensland in 2011, has led to increasing cases of congenital syphilis, including several deaths. Here, we applied multi-locus sequence typing (MLST) on available Treponema pallidum PCR-positive samples from the state of Queensland from the beginning of the outbreak to July 2020. In total, 393 samples from 337 males and 56 females were genotyped. Of 36 different Treponema pallidum sequence types (ST) observed, the two most common STs, ST 1 (also reported to be a dominant strain in various other countries) and ST 100 (the latter differing from ST 1 by only one single nucleotide polymorphism (SNP) based on the MLST scheme), together comprised 69% (271/393) of all samples, including the majority of samples in females (79%; 44/56). ST 1 was prevalent throughout the entire study period. Both strains remained the most common STs during the year 2020 where social distancing and other measures were implemented due to the COVID-19 pandemic. Both STs had high male-to-female ratios and included male rectal infections, therefore suggestive of occurrence primarily among men-who-have-sex-with-men (MSM). Hence, bridging from MSM to heterosexual networks may potentially contribute to infections among females, but further studies are needed to confirm this. Overall, there was considerable diversity of Treponema pallidum genotypes observed throughout the study period, but the fact that two key strains accounted for the majority of infections, including among females, stresses the need for further investigations into the transmission of these strains, and potentially a need for targeted public health interventions to better control the spread of syphilis in Queensland.

Risk of sustained SARS-CoV-2 transmission in Queensland, Australia.

We used an agent-based model Covasim to assess the risk of sustained community transmission of SARSCoV-2/COVID-19 in Queensland (Australia) in the presence of high-transmission variants of the virus. The model was calibrated using the demographics, policies, and interventions implemented in the state. Then, using the calibrated model, we simulated possible epidemic trajectories that could eventuate due to leakage of infected cases with high-transmission variants, during a period without recorded cases of locally acquired infections, known in Australian settings as "zero community transmission". We also examined how the threat of new variants reduces given a range of vaccination levels. Specifically, the model calibration covered the first-wave period from early March 2020 to May 2020. Predicted epidemic trajectories were simulated from early February 2021 to late March 2021. Our simulations showed that one infected agent with the ancestral (A.2.2) variant has a 14% chance of crossing a threshold of sustained community transmission (SCT) (i.e., > 5 infections per day, more than 3 days in a row), assuming no change in the prevailing preventative and counteracting policies. However, one agent carrying the alpha (B.1.1.7) variant has a 43% chance of crossing the same threshold; a threefold increase with respect to the ancestral strain; while, one agent carrying the delta (B.1.617.2) variant has a 60% chance of the same threshold, a fourfold increase with respect to the ancestral strain. The delta variant is 50% more likely to trigger SCT than the alpha variant. Doubling the average number of daily tests from ∼ 6,000 to 12,000 results in a decrease of this SCT probability from 43 to 33% for the alpha variant. However, if the delta variant is circulating we would need an average of 100,000 daily tests to achieve a similar decrease in SCT risk. Further, achieving a full-vaccination coverage of 70% of the adult population, with a vaccine with 70% effectiveness against infection, would decrease the probability of SCT from a single seed of alpha from 43 to 20%, on par with the ancestral strain in a naive population. In contrast, for the same vaccine coverage and same effectiveness, the probability of SCT from a single seed of delta would decrease from 62 to 48%, a risk slightly above the alpha variant in a naive population. Our results demonstrate that the introduction of even a small number of people infected with high-transmission variants dramatically increases the probability of sustained community transmission in Queensland. Until very high vaccine coverage is achieved, a swift implementation of policies and interventions, together with high quarantine adherence rates, will be required to minimise the probability of sustained community transmission.

Roles, experiences and perspectives of the stakeholders of "10,000 Lives" smoking cessation initiative in Central Queensland: Findings from an online survey during COVID-19 situation.

ISSUE ADDRESSED: The "10,000 Lives" initiative was launched in Central Queensland in November 2017 to reduce daily smoking prevalence to 9.5% by 2030 by promoting available smoking cessation interventions. One of the main strategies was to identify and engage possible stakeholders (local champions for the program) from hospitals and community organisations to increase conversations about smoking cessation and referrals to Quitline. We aimed to understand the roles, experiences and perceptions of stakeholders (possible champions for delivering smoking cessation support) of the "10,000 Lives" initiative in Central Queensland, Australia. METHODS: We conducted a mixed-method online survey during the COVID-19 situation (23 June 2020 to 22 August 2020) with a cross-section of possible stakeholders who were targeted for involvement in "10, 000 Lives" using a structured questionnaire with mostly closed-ended questions. Questions were asked regarding their roles, experiences and perceptions about smoking cessation and "10,000 Lives". RESULTS: Among the 110 respondents, 52 (47.3%) reported having provided smoking cessation support, including referral to Quitline, brief intervention and promoting existing interventions. Among them (n = 52), 31 (59.6%) were from hospitals and health services, 14 (26.9%) were from community services and three (5.8%) were from private medical practices while four of them did not report their setting. Twenty-five respondents (22.7%) self-identified as being directly involved with the "10, 000 Lives" initiative, which significantly predicted provision of smoking cessation support (OR 6.0, 95% CI: 2.1-19.8). However, a substantial proportion (63.5%) of those (n = 52) who reported delivering cessation support did not identify as contributing to "10,000 Lives". CONCLUSIONS: Stakeholders from hospitals, health services and community services are the main providers of smoking cessation support in Central Queensland. More could be done to support other stakeholders to feel confident about providing cessation support and to feel included in the initiative. SO WHAT?: Engaging with a range of stakeholders is critical for health promotion program success, to further develop the program and to ensure its sustainability. As such, funding needs to be allocated to the activities that enable this process to occur.

Impact of the COVID-19 pandemic on medical student placements in rural Queensland: A survey study.

OBJECTIVE: The COVID-19 pandemic has adversely impacted medical students' learning experiences. Students in one Australian Rural Clinical School were surveyed to investigate the impact of disruptions to clinical placements and satisfaction with educational changes implemented as a result of the pandemic. DESIGN: Cross-sectional survey. SETTING: The University of Queensland Rural Clinical School. METHODS: Students undertaking one or two years of study at the participating Rural Clinical School in November 2020. MAIN OUTCOME MEASURE: A 20-item anonymised survey with questions on personal health and safety, quality of clinical training experience, response to changes in learning and student environment, and progression to completion of the medical degree. RESULTS: The survey was completed by 124 students (76% response rate). Students were satisfied with the changes made to their learning to accommodate the disruptions to health service delivery and placements. Final year students were more satisfied with their learning experiences compared to their third-year counterparts. CONCLUSIONS: The Rural Clinical School implemented a range of academic and psychological support strategies which appear to have helped with mitigating mental health concerns experienced by students completing rural placements, who are already prone to experiencing social isolation. Strengthening communication between the academic and health service sectors can improve the quality of learning for medical students on placements.

Use of telemedicine for rheumatology practice in Queensland, Australia: experiences before and during the COVID-19 pandemic.

BACKGROUND: In Australia there is a shortage of rheumatologists potentially translating to poorer outcomes. A possible solution in this setting is telemedicine (TM). AIMS: To examine the utilisation and provider perceptions of TM in rheumatology in Queensland and explore the challenges faced when using TM before and during COVID-19. METHODS: A sequential mixed-methods study design was used. Rheumatologists completed a questionnaire on demographics, clinical practice, TM uptake, models of care and clinician perceptions of TM. The qualitative phase utilised purposeful sampling of active users of TM through in-depth semi-structured interviews. RESULTS: Thirty rheumatologists participated, with 76.7% identifying as active TM users. Use of TM was limited prior to COVID-19 with 80.9% examining less than five patients per week. Patient populations served by TM included capital city (53.3%), regional (63.3%) and rural/remote (23.3%). Most rheumatologists prescribed conventional or biological disease modifying agents (90% and 55%) through TM consultations. Barriers to TM use included low confidence in joint assessments, limited distribution of technology, access to administrative and peripheral clinical staff and lack of financial incentives. During the COVID-19 pandemic, a significant expansion of TM via telephone calls occurred and rheumatologists reported low confidence and satisfaction with this model. CONCLUSIONS: Familiarity with TM exists in this rheumatologist cohort; however, its use in routine practice is limited due to multiple barriers. The COVID-19 pandemic highlighted low confidence in telephone calls as a form of TM underlining the need for appropriate TM models of care for rheumatology practice.

The effect of resilience on the relationship between perceived stress and change in alcohol consumption during the COVID-19 pandemic in Queensland, Australia.

The COVID-19 pandemic has led to increased levels of stress and alcohol consumption. This study examined the effect of resilience on the relationship between stress and changes in alcohol consumption in the context of the COVID-19 pandemic in early 2020. A cross-sectional survey of 502 adults in Queensland, Australia (mean age = 45.68 (16.61)), found 23.9% of individuals had increased their alcohol consumption since the start of the pandemic. Regression modelling demonstrated a significant association between perceived stress and change in alcohol consumption. The study also revealed resilience was a moderating factor, where high levels of resilience buffered against increases in alcohol consumption associated with stress during the COVID-19 pandemic.
