"COVID-19 - A Perfect Storm": A Qualitative Exploration of Residential Care Facility Managers Perspectives on the Psychosocial Impacts of COVID-19

Growing evidence highlights the negative impact of managing the COVID-19 pandemic on the wellbeing of the healthcare workforce, including in the aged care sector. We undertook a qualitative study during the pandemic's third year to explore the psychosocial impacts on nine managers of residential care facilities (RCFs) across metropolitan and rural New South Wales, the largest state in Australia. Four themes were identified: (1) Increased pressure on maintaining aged care services, (2) Increased responsibility on RCF managers, (3) Psychosocial impacts due to accumulating pressures, and (4) Experience of beneficial supports. COVID-19 compounded pre-pandemic sector challenges and added new stressors. While resilient and resourceful, RCF managers experienced workplace stress and burnout, which may affect quality of resident care and impact on staff retention. There is a need for more investment to effectively support staff, and research to identify optimal psychosocial and management supports.

Implementing recommended COVID-19 public health measures in the era of living with COVID-19: Experiences of residential aged care facility managers in New South Wales, Australia

OBJECTIVES

To understand residential aged care facility (the facility) managers' perspectives on implementing public health measures (the measures) in their facilities in terms of barriers, facilitators and suggestions for improvement, after three years of the COVID-19 pandemic.

METHODS

Nine managers of the facilities without an active COVID-19 outbreak across New South Wales, Australia, representing metropolitan and rural locations, diverse facility size and star quality rating were interviewed (April-June 2023) and data qualitatively analysed.

RESULTS

Broader policy context, the need to balance the measures with resident well-being, facility-built infrastructure and mask fatigue were reported as barriers to implementation. Workplace policies, cultural embedding and local innovations were reported as facilitators. Suggested strategies included recommending the measures consistent with temporal COVID-19 risk; government agencies improving communication about the measures; mandatory staff vaccination; and simplified reporting requirements.

CONCLUSIONS

We recommend that relevant government agencies develop a single source of formalised, endorsed, up-to-date advice for the sector-specific COVID-19 information and communications; streamline outbreak notification and reporting requirements; and improve consultation with the sector.

Members' experiences and perceptions of participating in an Australian Regional One Health Network

BACKGROUND

The One Health framework is intended to optimise the interdependent health of humans, animals and ecosystems. It relies on effective collaborations across disciplines, sectors and communities. One Health networks have become increasingly important platforms for encouraging, creating and supporting collaborations. Their success is usually judged by evaluations of their outputs. However, there is also a need to understand member experiences and perceptions of the networks in which they participate. To that end, we undertook the first membership survey of a One Health network that was established in Australia in 2005.

METHODS

An online membership survey was created, comprising closed and open-ended questions.

RESULTS

Around one third of the Regional One Health Partnership ('the Network') participated in the study (33 members). Participants contributed a combined total of 170 years of experience in the Network and 414 years of combined experience working in/on One Health. The Network has provided excellent opportunities for cross sectoral collaboration that would otherwise not have been possible. Findings also highlighted the intangible benefits of membership such as the creation of a collaborative support group for emerging and established One Health practitioners.

CONCLUSIONS

The Network plays an important role in One Health collaborations in New South Wales and further afield. Commensurate with the literature on One Health collaborations globally, we identified a need for greater diversity amongst members, especially from First Nations people, local communities, non-government organisations and wildlife/environment experts, as well as concerted attempts to identify policy implications. Our membership survey tool could be adapted for future One Health Network membership surveys in Australia and internationally.

Epidemiology of Group A Streptococcal bacteraemia in Hunter New England Local Health District, 2008 to 2019

Invasive Group A Streptococcal infection (iGAS) is an uncommon but serious infection with Streptococcus pyogenes in a normally sterile body site. Manifestations include bacteraemia, necrotising fasciitis and toxic shock syndrome with attendant serious morbidity and mortality. An increasing incidence of iGAS has been observed in some regions of Australia. iGAS became a nationally notifiable condition from 1 July 2021. To determine if regional incidence has increased, and to identify priority populations, we undertook a retrospective data analysis of Group A Streptococcal (GAS) bacteraemia cases in Hunter New England Local Health District (HNELHD), New South Wales, Australia, from 1 January 2008 to 31 December 2019, as identified by NSW Health Pathology, John Hunter Hospital. A total of 486 cases were identified (age-standardised rate: 4.05 cases per 100,000 population per year). Incidence in HNELHD gradually increased over the study period (adjusted incidence rate ratio: 1.04; 95% confidence interval: 1.01-1.07) and was significantly higher in children under 5 years of age; in adults over 70 years of age; in males; and in First Nations peoples. A significant peak occurred in 2017 (9.00 cases per 100,000 population), the cause of which remains unclear. GAS bacteraemia is uncommon but severe, and incidence in HNELHD has slowly increased. Public health and clinical guidelines must address the needs of priority populations, which include young children, older adults and First Nations peoples. Routine surveillance and genomic analysis will help improve our understanding of iGAS and inform best public health management.

Embedding Aboriginal cultural governance, capacity, perspectives and leadership into a local Public Health Unit Incident Command System during COVID-19 in New South Wales, Australia

This case study describes the development and implementation of a governance structure that prioritised First Nations peoples in a local public health Incident Command System activated for the COVID-19 pandemic response in New South Wales, Australia. Using lessons learnt from past pandemics and planning exercises, public health leaders embedded an approach whereby First Nations peoples determined and led community and culturally informed pandemic control strategies and actions.In March 2020, First Nations governance was embedded into the local public health emergency response to COVID-19 in the Hunter New England region of New South Wales, Australia, enabling First Nations staff and community members to actively participate in strategic and operational decision-making with the objective of minimising COVID-19-related risks to First Nations peoples and communities. The model provided cultural insight and oversight to the local COVID-19 response; strengthened and advanced First Nations leadership; increased the First Nations public health workforce; led the development of First Nations disease surveillance strategies; and supported working groups to appropriately respond to local needs and priorities. This model demonstrates the feasibility of reframing a standard Incident Command System to embed and value First Nations principles of self-determination and empowerment to appropriately plan and respond to public health emergencies.

Involvement and readiness of fellows from Papua New Guinea's Field Epidemiology Training Programme in the COVID-19 response, 2020-2021

Problem

Fellows of the Papua New Guinea Field Epidemiology Training Programme (FETP) were part of the national coronavirus disease (COVID-19) response. However, the specific activities and challenges experienced by fellows in the field were unknown.

Context

The advanced FETP cohort commenced just before the COVID-19 pandemic and all fellows were involved in the response. The advanced fellows participating in this review represented a cross-section of the country's public health workforce.

Action

A review was conducted to better understand the scope of activities undertaken by FETP fellows, identify the challenges experienced and assess how well the programme prepared fellows for their COVID-19 response roles. A facilitated discussion based on the World Health Organization COVID-19 intra-action review methodology and an online survey was conducted with advanced FETP fellows.

Outcome

The fellows made important contributions to the national COVID-19 response by assuming leadership positions at all levels of government, leading training activities and applying core field epidemiology competencies in surveillance and response activities. The programme had prepared them well for the response, giving them the confidence and skills to undertake a diverse range of response roles.

Discussion

The FETP review of the COVID-19 response in Papua New Guinea highlighted the role and influence of the fellows during the pandemic response. Fellows were able to apply core field epidemiology competencies across a range of roles. The recommendations derived from this review will be instructive for the FETP specifically and the COVID-19 response generally.

Team effectiveness: epidemiologists' perception of collective performance during emergency response

BACKGROUND

To describe epidemiologists' experience of team dynamics and leadership during emergency response, and explore the utility of the Team Emergency Assessment Measure (TEAM) tool during future public health emergency responses. The TEAM tool included categories for leadership, teamwork, and task management.

METHODS

We conducted a cross-sectional survey between October 2019 and February 2020 with the global applied field epidemiology workforce. To validate the TEAM tool for our context, we used exploratory and confirmatory factor analysis.

RESULTS

We analysed 166 completed surveys. Respondents included national and international emergency responders with representation of all WHO regions. We were unable to validate the TEAM tool for use with epidemiology teams involved in emergency response, however descriptive analysis provided insight into epidemiology emergency response team performance. We found female responders were less satisfied with response leadership than male counterparts, and national responders were more satisfied across all survey categories compared to international responders.

CONCLUSION

Functional teams are a core attribute of effective public health emergency response. Our findings have shown a need for a greater focus on team performance. We recommend development of a fit-for-purpose performance management tool for teams responding to public health emergencies. The importance of building and supporting the development of the national workforce is another important finding of this study.

Estimating the future global dose demand for measles-rubella microarray patches

Background

Progress toward measles and rubella (MR) elimination has stagnated as countries are unable to reach the required 95% vaccine coverage. Microarray patches (MAPs) are anticipated to offer significant programmatic advantages to needle and syringe (N/S) presentation and increase MR vaccination coverage. A demand forecast analysis of the programmatic doses required (PDR) could accelerate MR-MAP development by informing the size and return of the investment required to manufacture MAPs.

Methods

Unconstrained global MR-MAP demand for 2030-2040 was estimated for three scenarios, for groups of countries with similar characteristics (archetypes), and four types of uses of MR-MAPs (use cases). The base scenario 1 assumed that MR-MAPs would replace a share of MR doses delivered by N/S, and that MAPs can reach a proportion of previously unimmunised populations. Scenario 2 assumed that MR-MAPs would be piloted in selected countries in each region of the World Health Organization (WHO); and scenario 3 explored introduction of MR-MAPs earlier in countries with the lowest measles vaccine coverage and highest MR disease burden. We conducted sensitivity analyses to measure the impact of data uncertainty.

Results

For the base scenario (1), the estimated global PDR for MR-MAPs was forecasted at 30 million doses in 2030 and increased to 220 million doses by 2040. Compared to scenario 1, scenario 2 resulted in an overall decrease in PDR of 18%, and scenario 3 resulted in a 21% increase in PDR between 2030 and 2040. Sensitivity analyses revealed that assumptions around the anticipated reach or coverage of MR-MAPs, particularly in the hard-to-reach and MOV populations, and the market penetration of MR-MAPs significantly impacted the estimated PDR.

Conclusions

Significant demand is expected for MR-MAPs between 2030 and 2040, however, efforts are required to address remaining data quality, uncertainties and gaps that underpin the assumptions in this analysis.

Key lessons from the COVID-19 public health response in Australia

Australia avoided the worst effects of the COVID-19 pandemic, but still experienced many negative impacts. Reflecting on lessons from Australia's public health response, an Australian expert panel composed of relevant discipline experts identified the following key lessons: 1) movement restrictions were effective, but their implementation requires careful consideration of adverse impacts, 2) disease modelling was valuable, but its limitations should be acknowledged, 3) the absence of timely national data requires re-assessment of national surveillance structures, 4) the utility of advanced pathogen genomics and novel vaccine technology was clearly demonstrated, 5) decision-making that is evidence informed and consultative is essential to maintain trust, 6) major system weaknesses in the residential aged-care sector require fixing, 7) adequate infection prevention and control frameworks are critically important, 8) the interests and needs of young people should not be compromised, 9) epidemics should be recognised as a 'standing threat', 10) regional and global solidarity is important. It should be acknowledged that we were unable to capture all relevant nuances and context specific differences. However, the intent of this review of Australia's public health response is to critically reflect on key lessons learnt and to encourage constructive national discussion in countries across the Western Pacific Region.

Transmission of SARS-CoV-2 Delta variant from an infected aircrew member on a short-haul domestic flight, Australia 2021

In June 2021, when COVID-19 incidence in Australia was low, a COVID-19 (Delta variant) cluster occurred on an 81-minute domestic flight, with an aircrew member as the likely source. Outbreak investigation demonstrated that SARS-CoV-2 may be transmitted during short-haul flights and that mask use protected against infection.

Willingness to adopt personal biosecurity strategies on thoroughbred breeding farms: Findings from a multi-site pilot study in Australia's Hunter Valley

There are almost 9,500 full-time employees in Australia's thoroughbred horse breeding industry. During foaling, they can be exposed to bodily fluids and mucous membranes which may present risks for zoonotic disease. These risks can be mitigated through personal biosecurity strategies. The aim of this study was to identify which personal biosecurity strategies were more or less likely to be adopted by workers. Seventeen participants representing 14 thoroughbred breeding farms and three equine veterinary practices in Australia's largest thoroughbred breeding region trialed up to 16 stakeholder-nominated personal biosecurity strategies over the 2021 foaling season. The strategies encompassed personal protective equipment (PPE), zoonotic disease awareness, policies and protocols, supportive environments, and leadership. Strategy adoption was monitored through three repeated self-audit surveys designed around the Transtheoretical Model of change (TTM) and findings were reviewed in exit interviews. For all survey waves in aggregate, 13 strategies were practiced by at least 50.0% of participants. Participants were most likely to use a ready-made foaling box (98.0%), communicate the message that PPE usage is a personal responsibility (94.1%) and use ready-made PPE kits (88.2%). However, 31.4% had no intention of doing practice sessions and/or dummy runs for PPE use and 27.5% had no intention of using a buddy system on farm/practice to check use of PPE. Whilst these rates indicate workers' willingness to adopt and maintain personal biosecurity strategies, they also indicate capacity for more practices to be implemented more often. Overall, the findings highlight the need for personal biosecurity interventions to be sensitive to the demands of the annual thoroughbred breeding calendar, the size of the breeding operation and the availability of skilled staff.

Tailoring childhood immunisation services in a socioeconomically disadvantaged community in New South Wales, Australia: a cost analysis

BACKGROUND

Using the World Health Organization's 'Guide to Tailoring Immunization Programmes' (TIP), a three-step program was developed by health services in partnership with a marginalised community in New South Wales, Australia. The aim was to improve immunisation rates of 1-year-old children. For Step 1, nurses identified and monitored local children overdue for immunisation from a national register, and sent parents or family doctors reminders by mail or telephone. For Step 2, parents were offered appointments at a local health centre; and for Step 3, they were offered home visits.

METHODS

An economic costing study was undertaken to examine the program's resource use. Costs were collected between 1 June 2020 and 31 May 2021. Case records were obtained for 139 children.

RESULTS

A total of 56 children became up to date after receiving TIP services; most after receiving Step 1 services (n =37). Total annual costs (A$) for the program were $34250 or $246 per case; or $612 per case becoming up to date. At $44 per case and $98 per case becoming up to date, Step 1B: personalised reminders, was the lowest costing step. Sensitivity analysis showed a possible 8% program savings through employment of nurses with a lower salary and use of video conference meetings.

CONCLUSION

This study provides information to the local health provider on the cost of TIP alongside their community-based programs. It also identified ways in which TIP could be made more cost-effective. Decision-makers can use this information to consider whether the investment in TIP is recommended.

High Attack Rate of Severe Acute Respiratory Syndrome Coronavirus 2 B.1.1.529 Among 2-Dose Vaccinated Populations in 2 Indoor Entertainment Setting Outbreaks

We estimated attack rates of severe acute respiratory syndrome coronavirus 2 Omicron (B.1.1.529) infection among people attending a nightclub and a graduation ball where >95% had at least 2 vaccine doses. Attack rates were 295 of 535 (55.1%) and 102 of 189 (54.0%), respectively (mean, 5 days postevent). At the ball, attack rates increased with time since vaccination: 12.5% among those vaccinated 1-2 months previously and 68.0% among those vaccinated ≥3 months previously; such differences were not found at the nightclub. Recent vaccination prevents Omicron infection, but is time and setting dependent, emphasizing the importance of nonpharmaceutical public health measures in addition to vaccine booster doses to maximize protection in high-risk contexts.

Accelerating the Development of Measles and Rubella Microarray Patches to Eliminate Measles and Rubella: Recent Progress, Remaining Challenges

Measles and rubella microarray patches (MR-MAPs) are critical in achieving measles and rubella eradication, a goal highly unlikely to meet with current vaccines presentations. With low commercial incentive to MAP developers, limited and uncertain funding, the need for investment in a novel manufacturing facility, and remaining questions about the source of antigen, product demand, and regulatory pathway, MR-MAPs are unlikely to be prequalified by WHO and ready for use before 2033. This article describes the current progress of MR-MAPs, highlights challenges and opportunities pertinent to MR-MAPs manufacturing, regulatory approval, creating demand, and timelines to licensure. It also describes activities that are being undertaken by multiple partners to incentivise investment in and accelerate the development of MR-MAPs.

Leadership, politics, and communication: challenges of the epidemiology workforce during emergency response

BACKGROUND

Improving the epidemiological response to emergencies requires an understanding of who the responders are, their role and skills, and the challenges they face during responses. In this paper, we explore the role of the epidemiologist and identify challenges they face during emergency response.

METHODS

We conducted a cross-sectional survey to learn more about epidemiologists who respond to public health emergencies. The online survey included open and closed-ended questions on challenges faced while responding, the roles of epidemiology responders, self-rating of skills, and support needed and received. We used purposive sampling to identify participants and a snowballing approach thereafter. We compared data by a number of characteristics, including national or international responder on their last response prior to the survey. We analysed the data using descriptive, content, and exploratory factor analysis.

RESULTS

We received 166 responses from individuals with experience in emergency response. The most frequently reported challenge was navigating the political dynamics of a response, which was more common for international responders than national. National responders experienced fewer challenges related to culture, language, and communication. Epidemiology responders reported a lack of response role clarity, limited knowledge sharing, and communication issues during emergency response. Sixty-seven percent of participants reported they needed support to do their job well; males who requested support were statistically more likely to receive it than females who asked.

CONCLUSIONS

Our study identified that national responders have additional strengths, such as better understanding of the local political environment, language, and culture, which may in turn support identification of local needs and priorities. Although this research was conducted prior to the COVID-19 pandemic, the results are even more relevant now. This research builds on emerging evidence on how to strengthen public health emergency response and provides a platform to begin a global conversation to address operational issues and the role of the international epidemiology responder.

How Australia's measles control activities have catalyzed rubella elimination

BACKGROUND

By 2017, rubella had been officially eliminated in Australia. This success was attributed to Australia's longstanding national immunization programme and two enhanced measles immunization activities using measles, mumps, and rubella (MMR) vaccines - the Measles Control Campaign (MCC) and the Young Adult MMR Campaign (YAC). Our study describes the impact of these activities on rubella incidence, and its elimination in Australia.

METHODS

Aggregate national serological survey data were assigned to birth cohorts, and mean, median, and age-group estimates calculated and analyzed against MMR immunization coverage estimates (1998-2018) and rubella notifications (1993-2018). Three-year cumulative incidences were calculated by birth cohort.

RESULTS

The serological surveys revealed high and stable levels of rubella immunity among females, but estimates for three male cohorts were lower. Since 2007, MMR immunization coverage among children aged 24-27 months has remained above 90% for both doses. The 3-year cumulative incidence of rubella declined across all birth cohorts following the MCC and the YAC.

DISCUSSION

Using MMR vaccines to address measles immunity gaps had the additional benefit of controlling rubella in Australia. Both the MCC and YAC shifted rubella epidemiology, accelerating the interruption of endemic transmission. Countries should consider combined measles and rubella vaccines for all catch-up activities.

A novel semi-quantitative methodology for national poliovirus reintroduction and outbreak risk assessment

BACKGROUND

Under the International Health Regulations (2005), World Health Organization Member States need to verify certification of polio-free status annually. In 2018, Australia sought to reassess and comprehensively characterise the risk posed by wild-type and vaccine-derived poliovirus introductions to national health security. However formal guidelines for national polio risk assessment were not publicly available.

METHODS

Four risk elements were identified and weighted using an expert-informed modified Delphi method: reintroduction hazard; population susceptibility; detection capability; and response capability. Australian data and qualitative evidence were analysed, documented and scored against risk element indicators to characterise polio risk as a semi-quantitative estimate and qualitative risk category statement.

RESULTS

The semi-quantitative risk characterisation calculated likelihood and impact scores of 0.43 and 0.13, respectively (possible range: 0.02-4.5). The assessment concluded that the risk of poliovirus reintroduction, resultant outbreaks of poliovirus infection, and sustained transmission occurring in Australia is very low.

CONCLUSIONS

Until poliovirus is eradicated, it remains in countries' strategic health security interest to maintain optimal investment in polio prevention, preparedness, surveillance and response capability to manage their level of risk. We present a structured, transparent and reproducible methodology for national or sub-national polio risk characterisation that generates evidence for targeted investment to maintain polio-free status.

Parent-level barriers to uptake of childhood vaccination: a global overview of systematic reviews

INTRODUCTION

Understanding barriers to childhood vaccination is crucial to inform effective interventions for maximising uptake. Published systematic reviews include different primary studies, producing varying lists of barriers. To make sense of this diverse body of literature, a comprehensive level of summary and synthesis is necessary. This overview of systematic reviews maps all potential parent-level barriers to childhood vaccination identified in systematic reviews. It synthesises these into a conceptual framework to inform development of a vaccine barriers assessment tool.

METHODS

We applied Joanna Briggs methodology, searching the Epistemonikos review database and reference lists of included reviews to June 2020. Systematic reviews of qualitative or quantitative data on parent-level barriers to routine vaccination in preschool-aged children were included. Reviews addressing influenza, reporting non-modifiable determinants or reporting barriers not relevant to parents were excluded. Where possible, we extracted review details, barrier descriptions and the number, setting and design of primary studies. Two authors independently screened search results and inductively coded barrier descriptions.

RESULTS

We screened 464 papers, identifying 30 relevant reviews with minimal overlap. Fourteen reviews included qualitative and quantitative primary studies, seven included quantitative and seven included qualitative studies only. Two did not report included study designs. Two-thirds of reviews (n=20; 67%) only included primary studies from high-income countries. We extracted 573 barrier descriptions and inductively coded these into 64 unique barriers in six overarching categories: (1) Access, (2) Clinic or Health System Barriers, (3) Concerns and Beliefs, (4) Health Perceptions and Experiences, (5) Knowledge and Information and (6) Social or Family Influence.

CONCLUSIONS

A global overview of systematic reviews of parent-level barriers to childhood vaccine uptake identified 64 barriers to inform development of a new comprehensive survey instrument. This instrument will assess both access and acceptance barriers to more accurately diagnose the reasons for under-vaccination in children in different settings.

Comparing inductive and deductive analysis techniques to understand health service implementation problems: a case study of childhood vaccination barriers

BACKGROUND

Effective implementation requires a comprehensive understanding of individual, organisational and system determinants. This study aimed to compare inductive and deductive analysis techniques to understand a complex implementation issue. We used childhood vaccination as a case study, an issue with wide-ranging barriers contributing to low-vaccine uptake internationally.

METHODS

The study is based on the Behaviour Change Wheel framework, which was derived from several levels of theory: the 3 components of the COM-B framework (capability, opportunity and motivation) can be mapped to the 14 domains of the Theoretical Domains Framework (TDF), which is based on 84 underlying constructs. We first conducted a review of systematic reviews of parent-level barriers to childhood vaccination. Subsequently we (1) inductively coded these barriers into a data-driven framework, using thematic analysis, and (2) deductively mapped the barriers to COM-B and TDF domains and constructs. These processes were undertaken by two authors independently, and discrepancies were resolved through discussion. Inductive and deductive results were compared.

RESULTS

The inductive process coded 583 descriptions of barriers identified from the literature into a framework of 74 barriers in 7 categories. The initial definitions used to map the barriers to deductive domains/constructs led to 89% agreement at the domain level. Resolving discrepancies required further definitions at the construct level. Of the 14 TDF domains, 10 were clearly identified in the data from the barrier reviews. Some domains were not specific enough to differentiate between types of barriers (e.g. Environmental Context and Resources), while other domains were not represented in the review data (e.g. Behavioural Regulation).

CONCLUSIONS

Using both inductive and deductive analysis techniques can help achieve a more comprehensive understanding of barriers to health service implementation. The inductive categories represented the review data in a clearer way than the theoretical domains, with better differentiation; but the missing deductive domains were useful as a way to identify additional issues to investigate further. Both analysis techniques resulted in a comprehensive list of barriers to vaccination that would not have been achieved using either approach alone. We recommend a hybrid approach combining TDF with broader frameworks, for future researchers conducting evidence syntheses.

Shaping applied epidemiology workforce training to strengthen emergency response: a global survey of applied epidemiologists, 2019-2020

BACKGROUND

Rapid and effective emergency response to address health security relies on a competent and suitably trained local and international workforce. The COVID-19 pandemic has highlighted that the health security workforce needs to be well equipped to tackle current and future challenges. In this study, we explored whether training in applied epidemiology was meeting the current needs of the applied epidemiology workforce.

METHOD

We conducted a cross-sectional online survey that was available in English and French. We used purposive and snowballing sampling techniques to identify potential survey respondents. An online social media advertisement campaign was used to disseminate a REDCap survey link between October 2019 and February 2020 through field epidemiology networks. Survey questions included demographic details of participants, along with their technical background, level of formal education, topics studied during epidemiology training, and years of experience as an epidemiologist. We used Pearson Chi-squared (Chi2) to test the difference between categorical variables, and content analysis to evaluate responses to open-ended questions.

RESULTS

In total, 282 people responded to the survey. Participants had a range of formal public health and epidemiology training backgrounds. Respondents applied epidemiology experience spanned almost 30 years, across 64 countries. Overall, 74% (n = 210) were alumni of Field Epidemiology Training Programs (FETP). Basic outbreak and surveillance training was well reported by respondents, however training in specialised techniques related to emergency response, communication, and leadership was less common. FETP graduates reported higher levels of formal training in all survey topics.

CONCLUSION

It is critical for the health security workforce to be well-trained and equipped with skills needed to ensure a rapid and effective response to acute public health events. Leadership, communication, interpersonal skills, and specialist training in emergency response are lacking in current training models. Our study has demonstrated that applied epidemiology workforce training must evolve to remain relevant to current and future public health challenges.

Impact of funding on influenza vaccine uptake in Australian children

Objectives and importance of study: Young children are at higher risk for serious influenza outcomes but, historically, Australian children aged less than 5 years have had low seasonal influenza vaccine uptake. In 2018, most Australian jurisdictions implemented funded influenza vaccine programs targeted at improving vaccine uptake in this age group. Our aim was to determine how successful these programs were at improving self-reported seasonal influenza vaccine uptake at the community level by comparing vaccination rates in each Australian jurisdiction before and after the introduction of funded vaccines for children aged 6 months to less than 5 years, as well as other age groups.

STUDY TYPE

Volunteer observational cohort study.

METHODS

Flutracking is an email-based surveillance tool for influenza-like illness that collects information about symptoms and influenza vaccination. We used historical data from 2014 to 2017 to estimate baseline vaccination status before funding of childhood influenza vaccines was introduced. We compared self-reported vaccine uptake in children younger than 5 years, children aged 5-17 years and adults (18-64 years, and 65 years and older) in 2018 and 2019 by state or territory. Mixed effects logistic regressions were used to measure the association between vaccination and a number of predictors, including whether the child was eligible for free vaccines, and whether adults resided with children or not.

RESULTS

We found large increases in vaccine uptake for children younger than 5 years in 2018 in all jurisdictions except Western Australia (where vaccines were already funded) and the Northern Territory (where funded vaccines were not introduced until 2019) that coincided with vaccine policy changes. Self-reported vaccination rates for young children in 2018 increased 2.7-4.2-fold in jurisdictions that funded the vaccine (compared with the previous, unfunded period). Being eligible for the funded vaccine was associated with much higher odds (odds ratio [OR] 4.75; 95% confidence interval [CI] 4.57, 4.79) of a young child being vaccinated. Older children and adults younger than 65 years were also more likely to receive the vaccine following policy changes.

CONCLUSION

The seasonal influenza vaccine is an important protective measure for those at risk of serious outcomes, including young children. Flutracking data demonstrates that government-funded vaccines can lead to an almost five-fold increase in self-reported vaccine uptake of the targeted age group, as well as previously unreported flow-on effects to older children. This suggests that funded vaccines for young children may encourage caregivers to also vaccinate themselves and their older children.

Emergency response and the need for collective competence in epidemiological teams

Objective

To determine the challenges met by, and needs of, the epidemiology emergency response workforce, with the aim of informing the development of a larger survey, by conducting key informant interviews of public health experts.

Methods

We defined our study population as public health experts with experience of epidemiology deployment. Using purposive sampling techniques, we applied random number sampling to shortlists of potential interviewees provided by key organizations to obtain 10 study participants; we identified three additional interviewees through snowballing. The same interviewer conducted all key informant interviews during May-August 2019. We thematically analysed de-identified transcripts using a qualitative data analysis computer software package.

Findings

Despite our interviewees having a wide range of organizational and field experience, common themes emerged. Interviewees reported a lack of clarity in the definition of an emergency response epidemiologist; the need for a broader range of skills; and inadequate leadership and mentoring in the field. Interviewees identified the lack of interpersonal skills (e.g. communication) and a lack of career progression options as limitations to the effectiveness of emergency response.

Conclusion

The epidemiology emergency response workforce is currently not achieving collective competence. The lack of a clear definition of the role must be addressed, and leadership is required to develop teams in which complementary skills are harmonized and those less experienced can be mentored. Epidemiology bodies must consider individual professional accreditation to ensure that the required skills are being achieved, as well as enabling continual professional development.

Assessing the Risk of Exotic Mosquito Incursion through an International Seaport, Newcastle, NSW, Australia

Exotic mosquitoes, especially container-inhabiting species such as Aedes aegypti and Aedes albopictus, pose a risk to Australia as they bring with them potentially significant pest and public health concerns. Notwithstanding the threat to public health and wellbeing, significant economic costs associated with the burden of mosquito control would fall to local authorities. Detection of these mosquitoes at airports and seaports has highlighted pathways of introduction but surveillance programs outside these first ports of entry are not routinely conducted in the majority of Australian cities. To assist local authorities to better prepare response plans for exotic mosquito incursions, an investigation was undertaken to determine the extent of habitats suitable for container-inhabiting mosquitoes in over 300 residential properties adjacent to the Port of Newcastle, Newcastle, NSW. More than 1500 water-holding containers were recorded, most commonly pot plant saucers, roof gutters, and water-holding plants (e.g., bromeliads). There were significantly more containers identified for properties classified as untidy but there was no evidence visible that property characteristics could be used to prioritise property surveys in a strategic eradication response. The results demonstrate that there is potential for local establishment of exotic mosquitoes and that considerable effort would be required to adequately survey these environments for the purpose of surveillance and eradication programs.

Examining Australian public perceptions and behaviors towards a future COVID-19 vaccine

BACKGROUND

As immunisation program launches have previously demonstrated, it is essential that careful planning occurs now to ensure the readiness of the public for a COVID-19 vaccine. As part of that process, this study aimed to understand the public perceptions regarding a future COVID-19 vaccine in Australia.

METHODS

A national cross-sectional online survey of 1420 Australian adults (18 years and older) was undertaken between 18 and 24 March 2020. The statistical analysis of the data included univariate and multivariable logistic regression model analysis.

RESULTS

Respondents generally held positive views towards vaccination. Eighty percent (n = 1143) agreed with the statement that getting myself vaccinated for COVID-19 would be a good way to protect myself against infection. Females (n = 614, 83%) were more likely to agree with the statement than males (n = 529, 78%) (aOR = 1.4 (95% CI: 1.1-1.8); P = 0.03), while 91% of those aged 70 years and above agreed compared to 76% of 18-29-year-olds (aOR = 2.3 (95% CI:1.2-4.1); P = 0.008). Agreement was also higher for those with a self-reported chronic disease (aOR = 1.4 (95% CI: 1.1-2.0); P = 0.04) and among those who held private health insurance (aOR = 1.7 (95% CI: 1.3-2.3); P < 0.001). Beyond individual perceptions, 78% stated that their decision to vaccinate would be supported by family and friends.

CONCLUSION

This study presents an early indication of public perceptions towards a future COVID-19 vaccine and represents a starting point for mapping vaccine perceptions. To support an effective launch of these new vaccines, governments need to use this time to understand the communities concerns and to identify the strategies that will support engagement.

Hendra in the Hunter Valley

In June 2019 the first equine case of Hendra virus in the Hunter Valley, New South Wales, Australia was detected. An urgent human and animal health response took place, involving biosecurity measures, contact tracing, promotion of equine vaccinations and investigation of flying fox activity in the area.

No human or additional animal cases occurred. Equine vaccination uptake increased by over 30-fold in the surrounding region in the three months following the case. Black flying fox and grey-headed flying fox species were detected in the Valley. The incident prompted review of Hendra virus resources at local and national levels.

This event near the “horse capital of Australia”, is the southernmost known equine Hendra case. Management of the event was facilitated by interagency collaboration involving human and animal health experts. Ongoing One Health partnerships are essential for successful responses to future zoonotic events.

The ethical case for global measles eradication—justice and the Rule of Rescue

Measles causes a substantial disease burden for all countries, while mortality is greatest in underserved, marginalized populations. Global measles eradication is feasible and the strategies critically rely upon well-functioning national immunisation programs and surveillance systems. All six regions of the World Health Organisation have adopted measles elimination targets. The Rule of Rescue and the principle of justice leave no ethical place for health programs, governments, global public health bodies or donors to hide if they impede efforts to eradicate measles globally by not taking all necessary actions to establish a global eradication target and committing the resources essential to achieve this goal.

Improving child immunisation rates in a disadvantaged community in New South Wales, Australia: a process evaluation for research translation

The World Health Organization's Tailoring Immunization Programmes approach was used to develop a new strategy to increase child vaccination coverage in a disadvantaged community in New South Wales, Australia, including reminders, outreach and home visiting. After 18 months, the strategy hasn't been fully implemented. A process evaluation was conducted to identify barriers and facilitators for research translation. Participants included child health nurses, Population Health staff, managers and general practitioners. The Capability-Opportunity-Motivation model of behaviour change (COM-B) was used to develop questions. Twenty-four participants took part in three focus groups and four interviews. Five themes emerged: (i) designing and adopting new ways of working is time-consuming and requires new skills, new ways of thinking and changes in service delivery; (ii) genuine engagement and interaction across fields and institutions helps build capacity and strengthen motivation; (iii) implementation of a new strategy requires clarity; who's doing what, when and how?; (iv) it is important not to lose sight of research findings related to the needs of disadvantaged families; and (v) trust in the process and perseverance are fundamental. There was strong motivation and opportunity for change, but a need to enhance service capability. Areas requiring support and resources were identified.

Identifying early changes in influenza vaccination uptake following a government funded immunisation program using a participatory community surveillance program

Following Australia’s severe influenza season in 2017, the health departments of the states and territories commenced funding in 2018 of influenza vaccine for all children aged six months to five years. As the national immunisation register has recently been extended to include recording of vaccination for all age groups, Australia’s community-based influenza-like illness (ILI) surveillance system, Flutracking, was used to explore influenza vaccine coverage in participants. Flutracking participants respond to a weekly survey about ILI from April to October each year. Participants report their influenza vaccine status with the current year’s vaccine in the first weekly survey, and if unvaccinated (or unknown), participants are prompted with the question weekly until the end of the Flutracking season. Detailed methods for Flutracking are available elsewhere.1 Self-reported vaccine coverage by age group (<5 years, 5 to 17 years, 18 to 64 years and ≥65 years) was calculated at 21 October (timing of the final 2018 Flutracking survey) for participants who had completed at least one survey in 2018. The five-year average was calculated for the percentage vaccinated at the end of the Flutracking survey for the years 2013 to 2017, and compared to 2018. Flutracking received ethics approval from the University of Newcastle (# 06/03/22.403) in 2006. In 2009 the program applied to the University of Newcastle to exit the ethics committee review as Flutracking had been incorporated into the national influenza surveillance system. The total number of participants completing at least one survey increased from 18,437 in 2013 to 45,532 in 2018. Flutracking participants are more likely to be female (59.8% compared to 50.4%) and more likely to have completed a postgraduate degree (22.6% compared to 3.6%) than the general Australian population.2 A relatively large proportion of Flutracking participants are health care workers, working face to face with patients (17.5%).

Asymptomatic COVID-19 or are we missing something?

A closer review of the asymptomatic COVID-19 cases recorded during the first pandemic wave in the Hunter New England area found that seven of the 26 ‘asymptomatic’ patients actually had experienced COVID-19-like symptoms, with five reporting symptoms prior to testing on review of all available clinical records. There is a need to delve deeper into the symptom history of ‘asymptomatic’ cases than initially recommended in national guidelines.

Study protocol: building an evidence base for epidemiology emergency response, a mixed-methods study

INTRODUCTION

Determinants and drivers for emergencies, such as political instability, weak health systems, climate change and forcibly displaced populations, are increasing the severity, complexity and frequency of public health emergencies. As emergencies become more complex, it is increasingly important that the required skillset of the emergency response workforce is clearly defined. To enable essential epidemiological activities to be implemented and managed during an emergency, a workforce is required with the right mix of skills, knowledge, experience and local context awareness. This study aims to provide local and international responders with an opportunity to actively contribute to the development of new thinking around emergency response roles and required competencies. In this study, we will develop recommendations using a broad range of evidence to address identified lessons and challenges so that future major emergency responses are culturally and contextually appropriate, and less reliant on long-term international deployments.

METHOD AND ANALYSIS

We will conduct a mixed-methods study using an exploratory sequential study design. The integration of four data sources, including key informant interviews, a scoping literature review, survey and semistructured interviews will allow the research questions to be examined in a flexible, semistructured way, from a range of perspectives. The study is unequally weighted, with a qualitative emphasis. We will analyse all activities as individual components, and then together in an integrated analysis. Thematic analysis will be conducted in NVivo V.11 and quantitative analysis will be conducted in Stata V.15.

ETHICS AND DISSEMINATION

All activities have been approved by the Science and Medical Delegated Ethics Review Committee at the Australian National University (protocol numbers 2018-521, 2018-641, 2019-068). Findings will be disseminated through international and local deployment partners, peer-reviewed publication, presentation at international conferences and through social media such as Twitter and Facebook.

COVID-19 is rapidly changing: Examining public perceptions and behaviors in response to this evolving pandemic

BACKGROUND

Since the emergence of SARS-CoV-2, the virus that causes coronavirus disease (COVID-19) in late 2019, communities have been required to rapidly adopt community mitigation strategies rarely used before, or only in limited settings. This study aimed to examine the attitudes and beliefs of Australian adults towards the COVID-19 pandemic, and willingness and capacity to engage with these mitigation measures. In addition, we aimed to explore the psychosocial and demographic factors that are associated with adoption of recommended hygiene-related and avoidance-related behaviors.

METHODS

A national cross-sectional online survey of 1420 Australian adults (18 years and older) was undertaken between the 18 and 24 March 2020. The statistical analysis of the data included univariate and multivariate logistic regression analysis.

FINDINGS

The survey of 1420 respondents found 50% (710) of respondents felt COVID-19 would 'somewhat' affect their health if infected and 19% perceived their level of risk as high or very high. 84·9% had performed ≥1 of the three recommended hygiene-related behaviors and 93·4% performed ≥1 of six avoidance-related behaviors over the last one month. Adopting avoidance behaviors was associated with trust in government/authorities (aOR: 6.0, 95% CI 2.6-11·0), higher perceived rating of effectiveness of behaviors (aOR: 4·0, 95% CI: 1·8-8·7), higher levels of perceived ability to adopt social distancing strategies (aOR: 5.0, 95% CI: 1·5-9.3), higher trust in government (aOR: 6.0, 95% CI: 2.6-11.0) and higher level of concern if self-isolated (aOR: 1.8, 95% CI: 1.1-3.0).

INTERPRETATION

In the last two months, members of the public have been inundated with messages about hygiene and social (physical) distancing. However, our results indicate that a continued focus on supporting community understanding of the rationale for these strategies, as well as instilling community confidence in their ability to adopt or sustain the recommendations is needed.
