RESUMO
BACKGROUND: Patients admitted from the emergency department to the wards, who progress to a critically unwell state, may require expeditious admission to the intensive care unit. It can be argued that earlier recognition of such patients, to facilitate prompt transfer to intensive care, could be linked to more favourable clinical outcomes. Nevertheless, this can be clinically challenging, and there are currently no established evidence-based methods for predicting the need for intensive care in the future. OBJECTIVES: We aimed to analyse the emergency department data to describe the characteristics of patients who required an intensive care admission within 48 h of presentation. Secondly, we planned to test the feasibility of using this data to identify the associated risk factors for developing a predictive model. METHODS: We designed a retrospective case-control study. Cases were patients admitted to intensive care within 48 h of their emergency department presentation. Controls were patients who did not need an intensive care admission. Groups were matched based on age, gender, admission calendar month, and diagnosis. To identify the associated variables, we used a conditional logistic regression model. RESULTS: Compared to controls, cases were more likely to be obese, and smokers and had a higher prevalence of cardiovascular (39 [35.1%] vs 20 [18%], p = 0.004) and respiratory diagnoses (45 [40.5%] vs 25 [22.5%], p = 0.004). They received more medical emergency team reviews (53 [47.8%] vs 24 [21.6%], p < 0.001), and more patients had an acute resuscitation plan (31 [27.9%] vs 15 [13.5%], p = 0.008). The predictive model showed that having acute resuscitation plans, cardiovascular and respiratory diagnoses, and receiving medical emergency team reviews were strongly associated with having an intensive care admission within 48 h of presentation. CONCLUSIONS: Our study used emergency department data to provide a detailed description of patients who had an intensive care unit admission within 48 h of their presentation. It demonstrated the feasibility of using such data to identify the associated risk factors to develop a predictive model.

BACKGROUND: The Australian Government implemented a range of public health response strategies and communication approaches to reduce the spread of COVID-19; however, concerns have been raised around a failure to sufficiently consider culturally and linguistically diverse (CaLD) communities in these processes. This research aimed to understand the factors that have impacted COVID-19 communication and engagement efforts during the pandemic from the perspective of key CaLD community and faith-based leaders. A further aim was to understand the processes that could be adopted to support future communication strategies, including promoting pandemic-related vaccines. APPROACH: This study included 29 key informant interviews with community and faith-based leaders in New South Wales, Australia. RESULTS: The overwhelming message from community leaders was a sense of shared responsibility between their organisations and governments in communicating pertinent and accurate COVID-19 related information to CaLD communities. They expressed a sense of duty to keep their community members safe. However, community leaders and others shouldered significant costs related to resources and time that need to be acknowledged by governments in preparing for future disease outbreaks. They felt that governments should consider: 1) improving communication between governments and CaLD organisations; 2) responding to the specific CaLD needs with greater agility; 3) foregrounding social media in their communication strategy; 4) reinvesting in local public health units to know their population; 5) developing a health ambassadors model program; 6) preparing a hybrid model of translators/interpreters to fill the gap; and, 7) reimagining vaccine information campaigns to target CaLD communities better. CONCLUSION: Given the technical details about the COVID-19 virus conveyed in government information campaigns and the media, ensuring the most vulnerable populations, including people from CaLD backgrounds, access clear, concise and timely public health messaging from governments and community organisations requires further attention.

BACKGROUND: Vaccine-preventable infections are generally well controlled in Australia. However, gaps in immunity can lead to outbreaks and are important to identify. Young adults are a highly mobile population and a potential source of imported infections. We aimed to evaluate anti- measles, mumps, rubella and varicella (MMR&V) IgG seroprevalence and explore factors relating to antibody seropositivity. METHODS: A cross-sectional online survey was conducted among students from a large Australian university to collect demographic, vaccination, infection and travel characteristics. Blood samples were collected to measure MMR&V seroprevalence. Logistic regression was used to identify factors associated with seropositivity. RESULTS: Among 804 university students, seroprevalence (positive or equivocal) for measles was 82.3% (95% CI 79.6-84.8%), mumps 79.5% (95% CI 76.7-82.3%), rubella 91.5% (95% CI 89.6-93.5%) and varicella 86.2% (95% CI 84.1-88.8%), with 452 (56.2%, 95% CI 52.8-59.6) seropositive to all four viruses. Varicella seropositivity was highest in the older birth cohort (born 1988-1991). Measles seropositivity was higher for international students compared to domestic students. Among international students, mumps seroprevalence was significantly lower than measles and rubella seroprevalence. International travel in the previous 12 months was reported by 63.1% of students, but only 18.2% of travellers reported seeking pre-travel health advice prior to most recent international travel. CONCLUSIONS: Overall, this study suggests immunity to MMR&V is sub-optimal. We found the university student population to be highly mobile and unlikely to seek pre-travel advice; thus, they are a potential source of infection importation. The implementation of university immunization policies could address the gaps identified and our findings can inform the development of targeted vaccination campaigns.

BACKGROUND: Intravenous immunoglobulin (IVIg) is a critical replacement therapy for immunodeficiencies and immunomodulatory treatment for autoimmune and inflammatory diseases. Adequate supply of IVIg is a global issue, necessitating supply restrictions. In Australia, despite strict criteria for use, demand for IVIg has increased over time and exceeds domestic supply. OBJECTIVE: Factors associated with the upward trend in overall IVIg use were examined, including in the number of unique patients, IVIg dosing and treatment frequency and variations by prescribing discipline and disease group. METHODS: De-identified data of IVIg dispensed in the largest Australian state (New South Wales) from 2007 to 2013 were provided by Australian Red Cross Lifeblood. Trends and projections were calculated using log-linear regression of unique patients, treatment episodes and grams of IVIg for overall use and use stratified by discipline and disease group. RESULTS: During the study period, 169 453 treatment episodes were recorded for 12 547 unique patients accounting for 5 827 787 g of IVIg use. Overall, IVIg use increased by 12.0% (11.5-12.6%) per year representing a 97.7% increase (91.6-104%) over the study period. The highest growth was among neurological conditions (16.0% (14.9-17.1%) per year). An increase in the number of unique patients was the primary driver of this growth, augmented by increases in the frequency and average dose per treatment. CONCLUSIONS: Clinically acceptable measures to improve management of IVIg supply are needed including optimising dose, frequency and duration of treatment. Formal evaluation of IVIg versus alternatives, including cost-effectiveness and comparative efficacy, is warranted.

INTRODUCTION: In 2016, Australia launched a whole life immunisation register, the Australian Immunisation Register (AIR), building on a universal childhood register established in 1997. Immunisation Information Systems are well established in Europe, the US and elsewhere. However, a national system covering immunisation across the lifespan, with complete capture of the population and satisfactory data quality, is rare. METHODS: A national workshop was convened in 2016 with key stakeholders from the government, new and existing vaccine users, and vaccine providers to review the ideal features of the AIR to ensure optimal effectiveness. This workshop focused on the functionality needed to identify population groups newly included in the register and support the achievement of high immunisation coverage in these groups eligible for National Immunisation Program vaccines. RESULTS: Key recommendations included the need for bidirectional data flow between the AIR and providers; systematic approaches to the capture and recording of accurate and complete data to ascertain important denominators for subpopulations, includingAboriginal and Torres Strait Islander status, medical risk factors, occupation, ethnicity, country of birth, and vaccines given during pregnancy; linkage with other government datasets including notifiable diseases; the capture of adverse events following immunisation; ease of access by patients, providers; and by researchers. CONCLUSIONS: Some recommendations from the workshop have informed the development and future utility of the AIR. Some recommendations from the workshop have been integrated into the current iteration of the AIR, which is more important than ever given the roll-out of COVID-19 vaccines. The accuracy and validity of data have subsequently improved through data entry controls, data integrity checks and reporting requirements. Access to AIR data for research remains protracted and costly, limitingresearch potential.

BACKGROUND: Gay and bisexual men (GBM) who use HIV preexposure prophylaxis (HIV-PrEP) have high rates of bacterial sexually transmitted infections (STIs). The use of daily antibiotics as STI preexposure prophylaxis (STI-PrEP) may be appealing to GBM who are using or have previously used HIV-PrEP (HIV-PrEP-experienced) for the prevention of bacterial STIs. METHODS: We examined willingness to use daily STI-PrEP among a cross-sectional sample of HIV-PrEP-experienced GBM in Australia who participated in an observational online cohort study from August 2018 to March 2020. Factors associated with willingness to use daily STI-PrEP were determined using bivariate and multivariate logistic regression. RESULTS: Of the 1347 participants, half (54.3%) were willing to use daily STI-PrEP. Factors independently associated with greater willingness to use daily STI-PrEP included having >10 sexual partners in the last 6 months, using methamphetamine in the last 6 months, being more conscious about avoiding STIs, having a greater number of STIs since commencing HIV-PrEP, being willing to take HIV-PrEP for as long as they were at risk of acquiring HIV, and only using condoms when a sexual partner requested them. Conversely, factors associated with less willingness to use daily STI-PrEP included being university educated, using nondaily dosing regimens of HIV-PrEP, preferring event-driven HIV-PrEP, and being concerned about long-term HIV-PrEP adverse effects. CONCLUSIONS: Sexually transmitted infection PrEP is likely to be appealing to many HIV-PrEP-experienced GBM, especially those who engage in activities associated with a higher risk of STI transmission. However, they are less likely to be willing to use STI-PrEP unless it aligns with their HIV-PrEP dosing regimen, suggesting that research into the safety and efficacy of alternative STI prophylaxis dosing options should be prioritized.

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.

BACKGROUND: Pretravel health advice can play a crucial role in improving both travelers' awareness about disease risk and compliance with preventive measures. General practitioners (GPs) and the internet have been reported internationally to be the main sources of health advice for travelers to non-mass gathering (MG) destinations. However, few studies have attempted to investigate the sources of health advice among travelers to MGs including the Hajj pilgrimage, and none of these studies further investigated the impact of pretravel advice on pilgrims' health behaviors. OBJECTIVE: The objective of this study was to investigate the impact of the source of pretravel health advice (from GPs and specialized Hajj travel agents) on Hajj pilgrims' awareness of and compliance with health recommendations, and the incidence of Hajj-associated illnesses. METHODS: A prospective cohort study (before and during Hajj) was conducted among Australian pilgrims aged ≥18 years in 2015. RESULTS: A total of 421 pilgrims participated prior to Hajj, and 391 (93%) provided follow-up data during Hajj. All participants obtained pretravel health advice from one or more sources, with Hajj travel agents (46%) and general practitioners (GPs; 40%) the most commonly reported sources. In total, 288 (74%) participants reported Hajj-related symptoms, of which 86% (248/288) were respiratory symptoms. Participants who obtained pretravel health advice from travel agents were more likely to be aware of the official Saudi recommendations (adjusted odds ratio [aOR] 2.1, 95% CI 1.2-3.8; P=.01), receive recommended vaccines before travel (aOR 2.4, 95% CI 1.4-3.9; P=.01), use hand sanitizers including soap (aOR 2.5, 95% CI 1.1-6.1; P=.03), and wash their hands after touching an ill person during Hajj (aOR 2.9, 95% CI 1.1-7.1; P=.01), compared to those who sought advice from GPs. However, neither advice from travel agents nor GPs was associated with a lower incidence of Hajj-related illnesses. CONCLUSIONS: Advice from travel agents appeared to be accessed by more travelers than that from GPs, and was associated with an increased likelihood of positive travel health behaviors.

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.

The role of hand hygiene in the prevention of respiratory tract infections in Hajj pilgrims has not been assessed through a focussed systematic review of the literature. Considering this, a systematic review was undertaken to synthesize the up-to-date literature on the compliance and effectiveness of hand hygiene among Hajj attendees. Major databases, including OVID Medline, were searched by using a combination of MeSH terms and text words for potentially relevant articles. Data from identified articles were abstracted, quality assessed and combined into a summary effect. Twelve observational studies containing data of 6,320 pilgrims were included. The compliance of hand washing with non-alcoholic surfactants was 77.7% (ranged from 31.5% to 90.3% in individual studies) and the compliance of hand cleaning with alcoholic products was 44.9% (ranged from 30.7% to 67.4%). Education was a key influencer of hand hygiene practice. Only three of the six studies that assessed the effectiveness of hand hygiene against clinical disease found the practice to be effective, and only one of the two studies that evaluated its effectiveness against a laboratory-confirmed infection found it to be effective. This systematic review suggests that hand hygiene using non-alcoholic products is generally acceptable among Hajj pilgrims but there is no conclusive evidence on its effectiveness.

BACKGROUND: High-quality vaccination data are critical to planning, implementation and evaluation of immunization programs. However, sub-optimal administrative vaccination data quality in low- and middle-income countries persist for heterogeneous reasons, though most relate to organizational factors and human behavior. The nationwide Data Improvement Team (DIT) strategy in Uganda aimed to strengthen human resource capacity to generate quality administrative vaccination data at the health facility. METHODS: A financial cost analysis of the Uganda DIT strategy (2014-2016) was conducted from the program funder perspective. Activity-based micro-costing from funder financial and program monitoring records was used to estimate total and unit costs by program area (in 2016 US dollars). Hypothetical scenarios were developed to illustrate potential approaches to reducing costs. RESULTS: Over 25 months the DIT strategy was implemented in all 116 operational districts and 3443 (89%) health facilities in Uganda at a total financial cost of US $575 275. Training and deployment of DITs accounted for the highest proportion of expenditure across program areas (69%). Transport, per diems, lodging, and honoraria for DIT members and national supervisors were the main cost drivers of the strategy. Deployment of 557 DIT members cost US $839 per DIT member, US $4 030 per district, and US $136 per health facility. The estimated opportunity cost of government staff time wasn't a major cost driver (2.5%) of total cost. CONCLUSION: The results provide the first estimates of the magnitude and drivers of cost to implement a national workforce capacity building strategy to improve administrative vaccination data quality in a low- or middle-income country. Financial costs are a critical input to combine with future outcome data to describe the cost of strategies relative to performance outcomes. The operational costs of the strategy were modest (0.5-1.6%) relative to the estimated operational costs of Uganda's national immunization program.

PURPOSE OF REVIEW: International migration is a global phenomenon that is growing in scope, complexity and impact. The inaugural International Society of Travel Medicine (ISTM) International Conference on Migration Health provided a forum to discuss scientific evidence on the broad issues relevant to migration health. This review summarises the key health issues, with a focus on infectious diseases, current effective strategies and future considerations presented at this forum and in the recent literature. RECENT FINDINGS: Migrants face health disparities for both communicable and non-communicable diseases. Their heightened infectious disease risks, compared to host populations, are related to pre-migration exposures, the circumstances of the migration journey and the receptivity and access to health services in their receiving countries. While the prevalence of infectious diseases identified through screening programmes are generally low, delays in diagnosis and treatment for a range of treatable infectious diseases result in higher morbidity and mortality among migrants. Barriers to care in host countries occur at the patient, provider and health systems levels. Coordinated and inclusive health services, healthcare systems and health policies, responsive to patient diversity reduce these barriers. Structural barriers to healthcare provision impede equitable care to migrants and refugees. Public health and medical professionals have a role in advocating for policy reforms.
RESUMO
INTRODUCTION: Immunisation is one of the most successful interventions for controlling infectious diseases but relies on continuous high coverage. Parental vaccine refusal and logistical barriers to access are threats to the success of immunisation programs, with resultant population immunity gaps leading to outbreaks of vaccine-preventable diseases. In Indonesia, coverage of childhood vaccines is suboptimal, with poor coverage of diphtheria-tetanus-pertussis vaccine leading to a large diphtheria outbreak in 2017. METHODS: To explore the underlying parents' reasons for incomplete childhood immunisation in Indonesia, semi-structured interviews were conducted in Tangerang Selatan, Banten Province, Indonesia. Sixteen purposively selected primary carers of partially and unimmunised children were interviewed. Transcripts were coded and analysed using inductive thematic analysis. RESULTS: Parental reasons were categorised into three interrelated themes of belief barriers, safety concerns, and issues of trust and misinformation. Stark differences were evident in reasons provided by carers of unimmunised children compared to partially immunised children. For parents of unimmunised children, Islamic beliefs, belief in the strength of natural immunity, and the use of alternative medicines strongly influenced behaviours. Safety concerns, issues of trust including distrust in the government, misinformation, and trust in information obtained through social networks were also prominent. In contrast, concerns about mild side-effects and logistical barriers outweighed beliefs among carers of partially immunised children. CONCLUSIONS: Our findings highlight the complexities in decision making for parents who decide not to vaccinate their children. In the Indonesian context, public health education and engagement of religious leaders to bridge the gap between religious beliefs and vaccine acceptance are needed to address vaccine refusal. Future research on the influence of social networks on vaccine hesitancy in the Indonesian context is also warranted. For parents of partially vaccinated children, interventions should focus on barriers of access to community health staff to encourage timely schedule completion.

BACKGROUND: Travel agents are known to be one of the main sources of health information for pilgrims, and their advice is associated with positive health behaviors. OBJECTIVE: This study aimed to investigate travel agents' health knowledge, what health advice they provide to the pilgrims, and their sources of health information. METHODS: In-depth interviews were conducted among specialist Hajj travel agents in Sydney, Australia. Thematic analysis was undertaken. RESULTS: Of the 13 accredited Hajj travel agents, 9 (69%) were interviewed. A high level of awareness regarding gastrointestinal infections, standard hygiene methods, and the risk of injury was noted among the participants and was included in advice provided to pilgrims. However, very limited knowledge and provision of advice about the risk of respiratory infections was identified. Knowledge of the compulsory meningococcal vaccine was high, and all participated travel agents reported influenza vaccine (a recommended vaccine) as a second "compulsory" vaccine for Hajj visas. Conversely, participants reported very limited knowledge about other recommended vaccines for Hajj. The Ministry of Hajj website and personal Hajj experience were the main sources of information. CONCLUSIONS: This study identifies a potential path for novel health promotion strategies to improve health knowledge among Hajj travel agents and subsequently among Hajj pilgrims.
RESUMO
Hepatitis A incidence has declined in most countries through a combination of prevention measures, augmented through the use of a highly effective vaccine. In Australia, the proportion of the population susceptible to hepatitis A infection has declined over time due to high rates of opportunistic vaccination as well as the sustained inflow of seropositive immigrants from high-endemicity countries. These factors have contributed to a rapid decline in incidence. An age-structured hepatitis A transmission model incorporating demographic changes was fitted to seroprevalence and disease notification data and used to project incidence trends and transmission potential for hepatitis A in the general population. Robustness of findings was assessed through worst-case scenarios regarding vaccine uptake, migration and the duration of immunity. The decline in age-specific seroprevalence until the introduction of hepatitis A vaccine in 1994 was well explained through a declining basic reproduction number (R0 ) that remained >1. Accounting for existing immunity, we estimated that the effective reproduction number (Reff ) <1 in the general population of Australia since the early 1990s, declining more rapidly after the introduction of the hepatitis A vaccine. Future projections under a variety of scenarios support Reff remaining <1 with continued low incidence in the general population. In conclusion, our results suggest that sustained endemic transmission in the general Australian population is no longer possible although risks of sporadic outbreaks remain. This suggests potential for local elimination of hepatitis A infection in Australia, provided that elimination criteria can be defined and satisfied in risk groups. The methodology used here to investigate elimination potential can easily be replicated in settings such as in the USA where sequential seroprevalence studies are supported by routine notification data.

BACKGROUND: migration has reached unprecedented levels, with 3.6% of the world's population living outside their country of birth. Migrants comprise a substantial proportion of high-income country populations, are at increased risk of a range of infectious diseases, compared to native-born populations and may experience worse health outcomes due to barriers accessing timely diagnoses and treatment. Poor access to essential healthcare services can be attributed to several factors, including language and cultural barriers and lack of specific inclusive health policies. METHODS: This review draws on evidence from the immigrant health and travel medicine literature, with a focus on infectious disease risks. It presents strategies to reduce barriers to healthcare access through health promotion and screening programs both at the community and clinic level and the delivery of linguistically and culturally competent care. The Methods: Salud Entre Culturas (SEC) 'Health Between Cultures' project from the Tropical Medicine Unit at the Hospital Ramon y Cajal in Madrid is described as an effective model of care. RESULTS: For those providing healthcare to migrant populations, the use of community-consulted approaches are considered best practice in the development of health education, health promotion and the delivery of targeted health services. At the clinic-level, strategies optimizing care for migrants include the use of bilingual healthcare professionals or community-based healthcare workers, cultural competence training of all clinic staff, the appropriate use of trained interpreters and the use of culturally appropriate health promotion materials. CONCLUSIONS: Multifaceted strategies are needed to improve access, community knowledge, community engagement and healthcare provider training to provide appropriate care to migrant populations to reduce infectious disease disparities.
