Enhancing the hepatitis B care cascade in Australia: A cost-effectiveness model.

If Australia is to successfully eliminate hepatitis B as a public health threat, it will need to enhance the chronic hepatitis B (CHB) care cascade. This study used a Markov model to assess the impact, cost and cost-effectiveness of scaling up CHB diagnosis, linkage to care and treatment to reach national and international elimination targets for hepatitis B in Australia. Compared to continued current trends, the model calculated the difference in care cascade projection, disability-adjusted life years (DALYs), costs and the incremental cost-effectiveness ratio (ICER), of scaling up CHB diagnosis, linkage to care and treatment to reach: (a) Australia's 2022 national targets and (b) the WHO's 2030 global targets. Achieving the national and WHO targets had ICERs of A$13 435 (A$10 236-A$21 165) and A$14 482 (A$13 031-A$25 641) per DALY averted between 2016 and 2030 in Australia, respectively. However, this excluded implementation and demand generation costs. The ICER for the National Strategy and WHO Strategy remained under A$50 000 per DALY averted if Australia spent up to A$328 or A$538 million, respectively, per annum (for 2016-2030) on implementation and demand generation activities. Sensitivity analysis showed that cost-effectiveness was predominately driven by the cost of CHB treatment and influenced by disease progression rates. Hence for Australia to reach the National Hepatitis B Strategy 2022 targets and WHO Strategy 2030 targets, it requires an improvement in the CHB care cascade. We estimated it is cost-effective to spend up to A$328 million or A$538 million per year to reach the National and WHO Strategy targets, respectively.

Development and pilot of a framework to evaluate reproductive health call centre services: experience of Marie Stopes international.

BACKGROUND: Call centres can improve the effectiveness of health services by helping reduce access barriers associated with stigma and geography. This project aimed to develop and pilot a standardised evaluation framework to assess Marie Stopes International reproductive health call centres. METHODS: Consultations were held with staff from the 14 existing international call centres to gauge current monitoring and evaluation processes, identify gaps, and establish evaluation needs. The draft framework was then piloted in the Marie Stopes Mexico call centre using client and provider surveys, mystery callers and a review of call centre records. RESULTS: A flexible framework was developed to allow call centres to measure the effectiveness of services offered. Nineteen indicators were developed to assess access, equity, quality and efficiency. The pilot found pre-defined ranges for indicators of access were not appropriate for a high-functioning call centre that was already achieving nearly 100% compliance. Several indicators could not be measured due to a lack of routine data collection systems. CONCLUSIONS: A standardised evaluation framework will allow comparisons over time and between call centres in different countries. Future assessments could be improved by establishing routine, reliable data collection systems prior to framework implementation. This is one of the first attempts to standardise the evaluation of a reproductive health call centre and establishes a method by which they can be monitored, and thus improved, over time.

Breaking down the barriers: a qualitative study to understand child oral health in refugee and migrant communities in Australia.

OBJECTIVE: Australia is an increasingly multicultural nation. Never before has the dental workforce been exposed to such language, cultural, religious and ethnic diversity. There is evidence that refugee and migrant children experience significantly poorer oral health than the nonmigrant population. However, little is known about the oral health knowledge, practices and beliefs of parents with young children from refugee and migrant backgrounds. The aim of this study was to identify the sociocultural influences on child oral health in these communities. DESIGN: Participatory and qualitative research methods were utilised. Partnerships were established with community agencies representing migrants from Iraq, Lebanon and Pakistan. Focus group discussions and semi-structured interviews were conducted with community members. Qualitative data were analysed thematically, combining focus group and interview data. RESULTS: Over 100 women participated in focus groups (n = 11) and semi-structured interviews (n = 7). Key findings included the knowledge, beliefs and practices concerning: caries risk factors, oral health practices and oral health literacy. Despite mothers' knowledge of the major causes of poor oral health - dietary changes, confusion about child oral hygiene practices and limited oral health literacy all influenced child oral health outcomes. CONCLUSION: This culturally competent qualitative study explores the sociocultural factors influencing child oral health in refugee and migrant communities. Understanding and acknowledging these factors are a prerequisite to determining where and how to intervene to improve oral health. Furthermore, it has implications for both dental and non-dental health professionals working to reduce health inequalities within such communities.

Setting the scene: locations for meeting sex partners among behaviorally bisexual men in Vientiane, Laos, and opportunities for health promotion.

Behaviorally bisexual men (BBM) in Vientiane, Laos report high-risk sexual behaviors. We explore settings for meeting sex partners and associated risk behaviors among BBM in Laos. BBM and their sexual partners were recruited in Vientiane Capital using modified snowball sampling (2010). Settings for usually meeting sex partners and associations with risk behaviors were assessed. Among 88 BBM, the most common settings for men meeting male, kathoey, and female sex partners were private residences (48%, 37%, 51%, respectively) and hospitality settings (39%, 31%, 40%, respectively). Hospitality settings were more commonly reported by heterosexual-identifying BBM, and private residences more commonly reported by bisexual/homosexual-identifying BBM. Inconsistent condom use was high across partners and settings. Meeting partners in hospitality settings was associated with reporting a high number of female sex partners and frequently drinking alcohol before sex. Our results suggest that targeted health promotion initiatives in bars, clubs, and beer-shops could reach a high proportion of high-risk bisexual men, particularly heterosexual-identifying BBM.

Overview of hepatitis B prevalence, prevention, and management in the Pacific Islands and Territories.

There are over 500-750 000 deaths per year because of hepatitis B virus (HBV)-related cirrhosis and liver cancer worldwide and the World Health Organization Western Pacific Region has some of the highest endemic levels of HBV in the world, particularly within China, South East Asia and Pacific Island Countries and Territories (PICT). The PICT have unique ethnic diversity and a very high prevalence of smoking and metabolic syndrome, both important risk factors for liver fibrosis and liver cancer. However, in contrast to many Asian countries, there is little published data on HBV prevalence and related liver disease burden in PICT. In this review, the available published literature and World Health Organization data for HBV prevalence and related liver disease and liver cancer burden in PICT is outlined, and unmet needs for improving HBV prevention and control in the region are highlighted.

An urgent need to scale-up injecting drug harm reduction services in Tanzania: prevalence of blood-borne viruses among drug users in Temeke District, Dar-es-Salaam, 2011.

BACKGROUND: Injecting drug use (IDU) is a growing concern in Tanzania compounded by reports of high-risk injecting and sexual risk behaviours among people who inject drugs (PWID). These behaviours have implications for transmission of blood-borne viruses, including HIV and hepatitis C (HCV). METHODS: We recruited 267 PWID (87% male) from Temeke District, Dar-es-Salaam through snowball and targeted sampling. A behavioural survey was administered alongside repeated rapid HIV and HCV antibody testing. HIV and HCV prevalence estimates with 95% confidence intervals (CIs) were calculated. RESULTS: Among PWID, 34.8% (95%CI 29.1-40.9) tested HIV positive (29.9% of males and 66.7% of females); 27.7% (95%CI 22.0-34.0) tested HCV antibody positive. Almost all (97%) participants were aware of HIV and 34% of HCV. 45% of male and 64% of female PWID reported a previous HIV test; only five (2%) PWID reported a previous HCV test. Of HIV and HCV positive tests, 73% and 99%, respectively, represented newly diagnosed infections. CONCLUSION: High prevalence of HIV and HCV were detected in this population of PWID. Rapid scale-up of targeted primary prevention and testing and treatment services for PWID in Tanzania is needed to prevent further transmission and consequent morbidities.

Reflections on cultural diversity in oral health promotion and prevention.

Dental caries is an extremely debilitating disease with lifelong consequences. In most developed countries significant oral health inequalities exist in disadvantaged communities, including refugee and migrant populations. Addressing these inequalities is becoming increasingly challenging as communities become more culturally diverse. An awareness of traditional oral health practices would enable the dental and broader health professions, to understand these differences and consequently better meet the needs of disadvantaged communities. The use of miswak is a common traditional oral hygiene practice used by a number of culturally diverse groups. Further research is required into the use and effectiveness of traditional oral health practices within developed countries. Such practices need to be understood, respected and incorporated within oral health care, policies and practices in order to reduce significant inequalities experienced in our communities. This commentary describes the current literature on miswak, its effectiveness and the implications for promoting oral health.

Formal and informal maternal health care: comparing the service provision of health facilities and village health volunteers in East Sepik Province.

Maternal health across Papua New Guinea (PNG) is of extreme public health concern. In response, the National Department of Health explicitly prioritized improving maternal, neonatal and child health services, envisaging increased collaboration between the formal health system and community-based initiatives as one method for achieving this. This study examined the patterns of formal and non-formal service utilization during pregnancy and childbirth in one province. We analysed the activity database of the East Sepik Women and Children's Health Project's Village Health Volunteer (VHV) program, an informal health service in East Sepik Province of PNG, estimating VHV activity and coverage for two maternal health care services (first antenatal care visit and VHV-attended deliveries) and comparing these to the volume and estimated coverage of these services delivered by the formal health system in East Sepik over the years 2007 to 2010. We found a significant increase in women's utilization of VHVs for first antenatal care and for an attended delivery. Reported coverage of these services delivered by the formal health service declined or at best remained static over the same time period. Our data cannot illuminate the causes of an apparent and highly concerning decline in health facility usage for assisted delivery, nor the reasons for increased usage of VHVs. The factors contributing to these trends in service provision require urgent study, to improve our understanding of the drivers of utilization of critical maternal health services. Our study demonstrates that VHVs deliver a substantial proportion of maternal health services in East Sepik. This finding alone highlights the importance of considering this cadre when planning health service improvements and suggests that a national VHV policy that builds on the work of the National Health Plan in defining the most appropriate role for VHVs in maternal health care is long overdue.
