Characterizing Socioecological Markers of Differentiated HIV Risk Among Men Who Have Sex with Men in Indonesia.

HIV prevention programs typically focus on changing individuals' risk behaviors, often without considering the socioecological factors that can moderate this risk. We characterized HIV risk among men who have sex with men (MSM) in Indonesia (n = 1314) using latent class analysis and used multinomial logistic regression to identify latent class relationships with demographics, social/sexual networks, and community-level socioecological indicators of HIV risk. Three HIV risk latent classes were identified-"Sexually Moderate" (n = 333), "Sexual Explorative" (n = 575), and "Navigating Complexities" (n = 406). Using "Sexually Moderate" (lowest risk) as the reference group, MSM in the "Sexual Explorative" class had additional social/sexual network-level risks (meeting partner(s) using both online and offline methods [RR = 3.8; 95%CI 1.7-8.6] or general social media and gay-specific online platforms [RR = 2.6; 95%CI 1.9-3.6] to meet partners, group sex [RR = 10.9; 95%CI 4.5-25.4], transactional sex [RR = 1.6; 95%CI 1.2-2.2]), and community-level risks (experiencing homosexual-related assaults [RR = 1.4; 95%CI 1.1-1.9]). MSM in the "Navigating Complexities" class had additional social/sexual network-level risks (low social support [RR = 1.6; 95%CI 1.1-2.5], less disclosure of their sexuality [RR = 1.4; 95%CI 1.0-1.9]) and community-level risks (higher internalized homonegativity scores [RR = 1.2; 95%CI 1.1-1.4], ever experiencing homosexual-related assaults [RR = 1.4:95%CI 1.1-1.9], less exposure to HIV/STI health promotion [RR = 0.7; 95%CI 0.5-0.9], attending STI-related services in the past 6 months [RR = 0.6; 95%CI 0.4-0.8]). Co-occurring individual and socioecological risk recommend holistic HIV prevention strategies tailored to consider the social and structural conditions of MSM in Indonesia are needed.

Patients' experience of accessing hepatitis C treatment through the Myanmar national hepatitis C treatment program: a qualitative evaluation.

BACKGROUND: Globally, 56.8 million people are living with hepatitis C and over three-quarters of those reside in low and middle-income countries (LMICs). Barriers and enablers to hepatitis C care among people who inject drugs in high-income countries are well documented. However, there is scant literature describing the patient experience in LMICs. Understanding the barriers and enablers to care from the patient perspective is important to inform service refinements to improve accessibility and acceptability of hepatitis C care. METHODS: We conducted a qualitative evaluation of the patient experience of accessing the national hepatitis C program at eight hospital sites in Myanmar. Semi-structured interviews were conducted with four to five participants per site. Interview data were analysed thematically, with deductive codes from Levesque et al.'s (2013) Framework on patient-centred access to healthcare. RESULTS: Across the eight sites, 38 participants who had completed treatment were interviewed. Barriers to accessing care were mostly related to attending for care and included travel time and costs, multiple appointments, and wait times. Some participants described how they did not receive adequate information on hepatitis C, particularly its transmission routes, and on the level of cirrhosis of their liver and what they were required to do after treatment (i.e. reduce alcohol consumption, liver cirrhosis monitoring). Many participants commented that they had few or no opportunities to ask questions. Provision of treatment at no cost was essential to accessibility, and gratitude for free treatment led to high acceptability of care, even when accessing care was inconvenient. CONCLUSIONS: These findings highlight the importance of streamlining and decentralising health services, adequate human resourcing and training, and affordable treatment in maximising the accessibility and acceptability of hepatitis C care in LMICs. Findings from this work will inform future service delivery refinements for national program and other decentralised programs to improve accessibility and acceptability of hepatitis C care in Myanmar.

Recruiting and retaining community-based participants in a COVID-19 longitudinal cohort and social networks study: lessons from Victoria, Australia.

BACKGROUND: Longitudinal studies are critical to informing evolving responses to COVID-19 but can be hampered by attrition bias, which undermines their reliability for guiding policy and practice. We describe recruitment and retention in the Optimise Study, a longitudinal cohort and social networks study that aimed to inform public health and policy responses to COVID-19. METHODS: Optimise recruited adults residing in Victoria, Australia September 01 2020-September 30 2021. High-frequency follow-up data collection included nominating social networks for study participation and completing a follow-up survey and four follow-up diaries each month, plus additional surveys if they tested positive for COVID-19 or were a close contact. This study compared number recruited to a-priori targets as of September 302,021, retention as of December 31 2021, comparing participants retained and not retained, and follow-up survey and diary completion October 2020-December 2021. Retained participants completed a follow-up survey or diary in each of the final three-months of their follow-up time. Attrition was defined by the number of participants not retained, divided by the number who completed a baseline survey by September 302,021. Survey completion was calculated as the proportion of follow-up surveys or diaries sent to participants that were completed between October 2020-December 2021. RESULTS: At September 302,021, 663 participants were recruited and at December 312,021, 563 were retained giving an overall attrition of 15% (n = 100/663). Among the 563 retained, survey completion was 90% (n = 19,354/21,524) for follow-up diaries and 89% (n = 4936/5560) for monthly follow-up surveys. Compared to participants not retained, those retained were older (t-test, p <  0.001), and more likely to be female (χ2, p = 0.001), and tertiary educated (χ2, p = 0.018). CONCLUSION: High levels of study retention and survey completion demonstrate a willingness to participate in a complex, longitudinal cohort study with high participant burden during a global pandemic. We believe comprehensive follow-up strategies, frequent dissemination of study findings to participants, and unique data collection systems have contributed to high levels of study retention.

Eliminating hepatitis C in Australia: a novel model of hepatitis C testing and treatment for people who inject drugs at a medically supervised injecting facility.

OBJECTIVE: To evaluate the feasibility of testing and treating people who inject drugs at a supervised injecting facility for hepatitis C virus (HCV) infection. DESIGN: Retrospective cohort study. SETTING, PARTICIPANTS: People who inject drugs who attended the Melbourne supervised injecting facility, 30 June 2018 - 30 June 2020. MAIN OUTCOME MEASURES: Proportion of people tested for hepatitis C; proportions of people positive for anti-HCV antibody and HCV RNA, and of eligible people prescribed direct-acting antiviral (DAA) treatment; sustained virological response twelve weeks or more after treatment completion. RESULTS: Of 4649 people who attended the supervised injecting facility during 2018-20, 321 were tested for hepatitis C (7%); 279 were anti-HCV antibody-positive (87%), of whom 143 (51%) were also HCV RNA-positive. Sixty-four of 321 had previously been treated for hepatitis C (20%), 21 had clinically identified cirrhosis (7%), eight had hepatitis B infections (2%), and four had human immunodeficiency virus infections (1%). In multivariate analyses, people tested for hepatitis C were more likely than untested clients to report psychiatric illness (adjusted odds ratio [aOR], 9.65; 95% confidence interval [CI], 7.26-12.8), not have a fixed address (aOR, 1.59; 95% CI, 1.18-2.14), and to report significant alcohol use (aOR, 1.57; 95% CI, 1.06-2.32). The median number of injecting facility visits was larger for those tested for hepatitis C (101; interquartile range [IQR], 31-236) than for those not tested (20; IQR, 3-90). DAA treatment was prescribed for 126 of 143 HCV RNA-positive clients (88%); 41 of 54 with complete follow-up data were cured (76%). CONCLUSIONS: People who attend supervised injecting facilities can be tested and treated for hepatitis C on site. Models that provide streamlined, convenient hepatitis C care promote engagement with treatment in a group in which the prevalence of hepatitis C is high.

Communication to promote and support physical distancing for COVID-19 prevention and control.

BACKGROUND: This review is an update of a rapid review undertaken in 2020 to identify relevant, feasible and effective communication approaches to promote acceptance, uptake and adherence to physical distancing measures for COVID-19 prevention and control. The rapid review was published when little was known about transmission, treatment or future vaccination, and when physical distancing measures (isolation, quarantine, contact tracing, crowd avoidance, work and school measures) were the cornerstone of public health responses globally. This updated review includes more recent evidence to extend what we know about effective pandemic public health communication. This includes considerations of changes needed over time to maintain responsiveness to pandemic transmission waves, the (in)equities and variable needs of groups within communities due to the pandemic, and highlights again the critical role of effective communication as integral to the public health response. OBJECTIVES: To update the evidence on the question 'What are relevant, feasible and effective communication approaches to promote acceptance, uptake and adherence to physical distancing measures for COVID-19 prevention and control?', our primary focus was communication approaches to promote and support acceptance, uptake and adherence to physical distancing. SECONDARY OBJECTIVE: to explore and identify key elements of effective communication for physical distancing measures for different (diverse) populations and groups. SEARCH METHODS: We searched MEDLINE, Embase and Cochrane Library databases from inception, with searches for this update including the period 1 January 2020 to 18 August 2021. Systematic review and study repositories and grey literature sources were searched in August 2021 and guidelines identified for the eCOVID19 Recommendations Map were screened (November 2021). SELECTION CRITERIA: Guidelines or reviews focusing on communication (information, education, reminders, facilitating decision-making, skills acquisition, supporting behaviour change, support, involvement in decision-making) related to physical distancing measures for prevention and/or control of COVID-19 or selected other diseases (sudden acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), influenza, Ebola virus disease (EVD) or tuberculosis (TB)) were included. New evidence was added to guidelines, reviews and primary studies included in the 2020 review. DATA COLLECTION AND ANALYSIS: Methods were based on the original rapid review, using methods developed by McMaster University and informed by Cochrane rapid review guidance. Screening, data extraction, quality assessment and synthesis were conducted by one author and checked by a second author. Synthesis of results was conducted using modified framework analysis, with themes from the original review used as an initial framework. MAIN RESULTS: This review update includes 68 studies, with 17 guidelines and 20 reviews added to the original 31 studies. Synthesis identified six major themes, which can be used to inform policy and decision-making related to planning and implementing communication about a public health emergency and measures to protect the community. Theme 1: Strengthening public trust and countering misinformation: essential foundations for effective public health communication Recognising the key role of public trust is essential. Working to build and maintain trust over time underpins the success of public health communications and, therefore, the effectiveness of public health prevention measures. Theme 2: Two-way communication: involving communities to improve the dissemination, accessibility and acceptability of information Two-way communication (engagement) with the public is needed over the course of a public health emergency: at first, recognition of a health threat (despite uncertainties), and regularly as public health measures are introduced or adjusted. Engagement needs to be embedded at all stages of the response and inform tailoring of communications and implementation of public health measures over time. Theme 3: Development of and preparation for public communication: target audience, equity and tailoring Communication and information must be tailored to reach all groups within populations, and explicitly consider existing inequities and the needs of disadvantaged groups, including those who are underserved, vulnerable, from diverse cultural or language groups, or who have lower educational attainment. Awareness that implementing public health measures may magnify existing or emerging inequities is also needed in response planning, enactment and adjustment over time. Theme 4: Public communication features: content, timing and duration, delivery Public communication needs to be based on clear, consistent, actionable and timely (up-to-date) information about preventive measures, including the benefits (whether for individual, social groupings or wider society), harms (likewise) and rationale for use, and include information about supports available to help follow recommended measures. Communication needs to occur through multiple channels and/or formats to build public trust and reach more of the community. Theme 5: Supporting behaviour change at individual and population levels Supporting implementation of public health measures with practical supports and services (e.g. essential supplies, financial support) is critical. Information about available supports must be widely disseminated and well understood. Supports and communication related to them require flexibility and tailoring to explicitly consider community needs, including those of vulnerable groups. Proactively monitoring and countering stigma related to preventive measures (e.g. quarantine) is also necessary to support adherence. Theme 6: Fostering and sustaining receptiveness and responsiveness to public health communication Efforts to foster and sustain public receptiveness and responsiveness to public health communication are needed throughout a public health emergency. Trust, acceptance and behaviours change over time, and communication needs to be adaptive and responsive to these changing needs. Ongoing community engagement efforts should inform communication and public health response measures. AUTHORS' CONCLUSIONS: Implications for practice Evidence highlights the critical role of communication throughout a public health emergency. Like any intervention, communication can be done well or poorly, but the consequences of poor communication during a pandemic may mean the difference between life and death. The approaches to effective communication identified in this review can be used by policymakers and decision-makers, working closely with communication teams, to plan, implement and adjust public communications over the course of a public health emergency like the COVID-19 pandemic. Implications for research Despite massive growth in research during the COVID-19 period, gaps in the evidence persist and require high-quality, meaningful research. This includes investigating the experiences of people at heightened COVID-19 risk, and identifying barriers to implementing public communication and protective health measures particular to lower- and middle-income countries, and how to overcome these.

Evaluation of a person-centred, nurse-led model of care delivering hepatitis C testing and treatment in priority settings: a mixed-methods evaluation of the Tasmanian Eliminate Hepatitis C Australia Outreach Project, 2020-2022.

INTRODUCTION: Australia has experienced sustained reductions in hepatitis C testing and treatment and may miss its 2030 elimination targets. Addressing gaps in community-based hepatitis C prescribing in priority settings that did not have, or did not prioritise, hepatitis C testing and treatment care pathways is critical. METHODS: The Tasmanian Eliminate Hepatitis C Australia Outreach Project delivered a nurse-led outreach model of care servicing hepatitis C priority populations in the community through the Tasmanian Statewide Sexual Health Service, supported by the Eliminating Hepatitis C Australia partnership. Settings included alcohol and other drug services, needle and syringe programs and mental health services. The project provided clients with clinical care across the hepatitis C cascade of care, including testing, treatment, and post-treatment support and hepatitis C education for staff. RESULTS: Between July 2020 and July 2022, a total of 43 sites were visited by one Clinical Nurse Consultant. There was a total of 695 interactions with clients across 219 days of service delivery by the Clinical Nurse Consultant. A total of 383 clients were tested for hepatitis C (antibody, RNA, or both). A total of 75 clients were diagnosed with hepatitis C RNA, of which 95% (71/75) commenced treatment, 83% (62/75) completed treatment and 52% (39/75) received a negative hepatitis C RNA test at least 12 weeks after treatment completion. CONCLUSIONS: Providing outreach hepatitis C services in community-based services was effective in engaging people living with and at-risk of hepatitis C, in education, testing, and care. Nurse-led, person-centred care was critical to the success of the project. Our evaluation underscores the importance of employing a partnership approach when delivering hepatitis C models of care in community settings, and incorporating workforce education and capacity-building activities when working with non-specialist healthcare professionals.

Pre-Empting Stigma and Complicating Trauma: Narratives of Gay and Bisexual Men who Inject Drugs in Australia.

Gay and bisexual men (GBM) report higher rates of sexualised and injecting drug use (IDU) than heterosexual men. Injecting-related stigma is linked to negative health outcomes among people who inject drugs (PWID). This paper describes the ways in which stigmatisation manifests in the narratives of GBM who inject drugs. We conducted in-depth interviews with Australian GBM with IDU histories, exploring drug use, pleasure, risk, and relationality. Data were analysed using discourse analytical approaches. Interviewees (n = 19), aged 24-60 years, narrated their experiences of IDU practice over 2-32 years. Most (n = 18) injected methamphetamine, and used other (non-injected) drugs, in sexual contexts. From participants' narratives, we developed two themes related to stigmatisation of PWID that illustrate the limitations of conventional drug discourses to narrate GBM's experiences. The first theme captures participants' attempts to pre-empt stigmatisation, outlining the layering of stigma faced by GBM who inject drugs. Linguistically, participants transformed injecting stigma by distinguishing their personal practice from that of more discreditable drug users. Practically, they mitigated stigmatisation by keeping discrediting information from others. The second theme illustrates how by complicating the stereotypes of IDU, participants took up prominent discursive practices linking IDU with trauma and pathology. Participants exerted agency by broadening available interpretive repertoires for understanding IDU among GBM, thus creating a counter-discourse. We argue that mainstream discursive practices reverberate through gay communities, perpetuating stigmatisation of PWID and inhibiting care-seeking. More narration of unconventional experiences, beyond insular social groups and critical scholarship, is needed in public discourse to effect destigmatisation.

The impact of point-of-care hepatitis C testing in needle and syringe exchange programs on linkage to care and treatment uptake among people who inject drugs: An Australian pilot study.

Point-of-care (POC) diagnostics overcome barriers to conventional hepatitis C (HCV) testing in people who inject drugs. This study assessed impact on hepatitis C treatment uptake of POC HCV testing in needle and syringe exchange programs (NSPs). Rapid EC was a single-arm interventional pilot study of HCV POC testing conducted in three inner-city community clinics with NSPs. Twelve months after the POC testing, a retrospective medical record and Pharmaceutical Benefits Scheme audit was performed to determine the number of HCV RNA-positive participants who were prescribed HCV treatment. 70 HCV RNA-positive Rapid EC study participants were included. 44 (63%) were prescribed DAAs; 26 (59%) completed treatment and 15 (34%) had SVR testing, all of whom were cured. Age ≥ 40 years (aOR 3.45, 95% CI 1.10-11.05, p = .03) and secondary school education (aOR 5.8, 95% CI 1.54-21.80, p = .009) had higher likelihood of being prescribed DAAs, whereas homelessness was inversely associated with prescription of DAAs (aOR 0.30, 95% CI 0.09-1.04, p = .057). Median time to receive a DAA script from date of diagnosis was seven days (IQR 0 to 14 days), and time to filling the DAA prescription was 2 days (IQR 0-12 days). In conclusion, provision of POC testing through NSPs was effective for linking new clients to HCV treatment and reduced the time to treatment. Further studies are needed to define the most cost-effective use of POC testing in models of care for people who inject drugs to increase HCV treatment uptake.

Impact of COVID-19 lockdown restrictions on hepatitis C testing in Australian primary care services providing care for people who inject drugs.

In 2020, the Australian state of Victoria experienced the longest COVID-19 lockdowns of any jurisdiction, with two lockdowns starting in March and July, respectively. Lockdowns may impact progress towards eliminating hepatitis C through reductions in hepatitis C testing. To examine the impact of lockdowns on hepatitis C testing in Victoria, de-identified data were extracted from a network of 11 services that specialize in the care of people who inject drugs (PWID). Interrupted time-series analyses estimated weekly changes in hepatitis C antibody and RNA testing from 1 January 2019 to 14 May 2021 and described temporal changes in testing associated with lockdowns. Interruptions were defined at the weeks corresponding to the start of the first lockdown (week 14) and the start (week 80) and end (week 95) of the second lockdown. Pre-COVID, an average of 80.6 antibody and 25.7 RNA tests were performed each week. Following the first lockdown in Victoria, there was an immediate drop of 23.2 antibody tests and 8.6 RNA tests per week (equivalent to a 31% and 46% drop, respectively). Following the second lockdown, there was an immediate drop of 17.2 antibody tests and 4.6 RNA tests per week (equivalent to a 26% and 33% drop, respectively). With testing and case finding identified as a key challenge to Australia achieving hepatitis C elimination targets, the cumulative number of testing opportunities missed during lockdowns may prolong efforts to find, diagnose and engage or reengage in care of the remaining population of PWID living with hepatitis C.

Digitalization of routine health information systems: Bangladesh, Indonesia, Pakistan.

Objective: To describe a systematic process of transforming paper registers into a digital system optimized to enhance service provision and fulfil reporting requirements. Methods: We designed a formative study around primary health workers providing reproductive, maternal, newborn and child health services in three countries in Bangladesh, Indonesia and Pakistan. The study ran from November 2014 to June 2018. We developed a prototype digital application after conducting a needs assessment of health workers' responsibilities, workflows, routine data requirements and service delivery needs. Methods included desk reviews, focus group discussions, in-depth interviews; data mapping of paper registers; observations of health workers; co-design workshops with health workers; and usability testing. Finally, we conducted an observational feasibility assessment to monitor uptake of the application. Findings: Researchers reviewed a total of 17 paper registers across the sites, which we transformed into seven modules within a digital application running on mobile devices. Modules corresponded to the services provided, including household enumeration, antenatal care, family planning, immunization, nutrition and child health. A total of 65 health workers used the modules during the feasibility assessment, and average weekly form submissions ranged from 8 to 234, depending on the health worker and their responsibilities. We also observed variability in the use of modules, requiring consistent monitoring support for health workers. Conclusion: Lessons learnt from this study shaped key global initiatives and resulted in a software global good. The deployment of digital systems requires well-designed applications, change management and strengthening human resources to realize and sustain health system gains.

A New Method for Estimating the Incidence of Infectious Diseases.

Ambitious World Health Organization targets for disease elimination require monitoring of epidemics using routine health data in settings of decreasing and low incidence. We evaluated 2 methods commonly applied to routine testing results to estimate incidence rates that assume a uniform probability of infection between consecutive negative and positive tests based on 1) the midpoint of this interval and 2) a randomly selected point in this interval. We compared these with an approximation of the Poisson binomial distribution, which assigns partial incidence to time periods based on the uniform probability of occurrence in these intervals. We assessed bias, variance, and convergence of estimates using simulations of Weibull-distributed failure times with systematically varied baseline incidence and varying trend. We considered results for quarterly, half-yearly, and yearly incidence estimation frequencies. We applied the methods to assess human immunodeficiency virus (HIV) incidence in HIV-negative patients from the Treatment With Antiretrovirals and Their Impact on Positive and Negative Men (TAIPAN) Study, an Australian study of HIV incidence in men who have sex with men, between 2012 and 2018. The Poisson binomial method had reduced bias and variance at low levels of incidence and for increased estimation frequency, with increased consistency of estimation. Application of methods to real-world assessment of HIV incidence found decreased variance in Poisson binomial model estimates, with observed incidence declining to levels where simulation results had indicated bias in midpoint and random-point methods.

A global investment framework for the elimination of hepatitis B.

BACKGROUND & AIMS: More than 292 million people are living with hepatitis B worldwide and are at risk of death from cirrhosis and liver cancer. The World Health Organization (WHO) has set global targets for the elimination of viral hepatitis as a public health threat by 2030. However, current levels of global investment in viral hepatitis elimination programmes are insufficient to achieve these goals. METHODS: To catalyse political commitment and to encourage domestic and international financing, we used published modelling data and key stakeholder interviews to develop an investment framework to demonstrate the return on investment for viral hepatitis elimination. RESULTS: The framework utilises a public health approach to identify evidence-based national activities that reduce viral hepatitis-related morbidity and mortality, as well as international activities and critical enablers that allow countries to achieve maximum impact on health outcomes from their investments - in the context of the WHO's 2030 viral elimination targets. CONCLUSION: Focusing on hepatitis B, this health policy paper employs the investment framework to estimate the substantial economic benefits of investing in the elimination of hepatitis B and demonstrates how such investments could be cost saving by 2030. LAY SUMMARY: Hepatitis B infection is a major cause of death from liver disease and liver cancer globally. To reduce deaths from hepatitis B infection, we need more people to be tested and treated for hepatitis B. In this paper, we outline a framework of activities to reduce hepatitis B-related deaths and discuss ways in which governments could pay for them.

A modelling analysis of financial incentives for hepatitis C testing and treatment uptake delivered through a community-based testing campaign.

Financial incentives may reduce opportunity costs associated with people who become lost to follow-up in hepatitis C treatment programs. We estimated the impact that different financial incentive amounts would need to have on retention in care to maintain the same unit cost per (1) RNA-positive person completing testing (defined as awareness of RNA status) and (2) RNA diagnosed person initiating treatment. Costing data were obtained from a 2019 community-based testing campaign focused on engaging people who inject drugs. For different financial incentive amounts, we modelled the corresponding improvements in retention in care that would be needed to maintain the same overall (1) unit cost per testing completion and (2) unit cost per treatment initiation. In the testing campaign, the unit cost per RNA-positive person completing testing was A$3215 and the unit cost per RNA diagnosed person initiating treatment was A$1055. Modelling found that an incentive of A$500 per RNA-positive person completing testing would result in more people completing testing for the same unit cost if the percentage of attendees receiving their test results increased from 63% to 74%. An incentive of A$200 per RNA diagnosed person initiating treatment would result in more people initiating treatment for the same unit cost if the percentage initiating treatment increased from 67% to 83%. Monetary incentives for completing testing and initiating treatment may be an effective way to increase retention in care without increasing the overall unit cost of completing testing/initiating treatment.

Health service utilization and experiences of stigma amongst people who inject drugs in Melbourne, Australia.

Whilst the testing and treatment of people who inject drugs (PWID) in Australia is a priority for local hepatitis C (HCV) elimination efforts, perceived stigma related to injecting drug use (IDU) has been identified as a major barrier for PWID engaging in health services. We used data from the EC Experience cohort study to explore associations between IDU-related perceived stigma and the number of different health services accessed by PWID in Melbourne, Australia. Data from the baseline questionnaire were used. Primary outcome was self-reported experience of stigma due to IDU (never, rarely, sometimes, often, always) in the previous 12 months. An ordinal logistic regression model assessed the association between stigma experienced and the number of different health services used (1-2, 3-4, 5-6, 7-10 different services) adjusted for recent IDU and key socio-demographics. Between September 2018 and February 2020, 281 participants were recruited from four health services. Sixty-nine per cent were male, median age was 42, 83% reported past-month IDU, 34% had never tested/tested >12 months, 8% tested negative <12 months, 43% were HCV-positive but not treated and 16% had been treated. Those accessing 5-6 services had 2.2 times greater odds of experiencing stigma (95% CI 0.86-6.65) compared with those using <5 services and those reporting 7-10 services had 2.43 times greater odds of experiencing stigma (95% CI 0.85-6.92) compared with those accessing <7 services. In conclusion, experiences of stigma may not necessarily be a barrier for PWID to access health services, but high rates of health service use may further expose, exacerbate or exaggerate stigma amongst PWID. Further examination of how stigma may be in/directly impact on hepatitis C treatment uptake is important and place-based interventions aimed at reducing stigma experienced by PWID may be needed.

Implications of HIV Self-Testing for Other Sexually Transmissible Infection Testing and Broader Sexual Health Needs: A Mixed-Methods Study of Gay and Bisexual Men in Australia.

BACKGROUND: Although HIV self-tests can support frequent HIV testing, their impact on attending clinics for other sexually transmissible infection (STI) testing and sexual health care is largely unknown. We explored intentions to use HIV self-tests and how this might affect patterns of attending sexual health services among gay, bisexual, and other men who have sex with men (GBM) in Victoria, Australia. METHODS: Gay, bisexual, and other men who have sex with men self-completed an online survey between March 10 and June 10, 2019. Among GBM reporting lifetime HIV testing and intentions to self-test at least once annually, we used logistic regression to identify correlates of intending to replace clinic-based HIV testing with self-tests. Qualitative interviews with purposively selected survey participants undertaken between May and June 2019 explored the implications of self-testing on clinic-based sexual health care. RESULTS: Of the 279 survey participants, 79 (29%) reported they would replace most or all clinic-based HIV tests with self-tests, with longer time since last testing for HIV and younger age associated with reporting this outcome in the multivariate analysis. Qualitative interviews revealed different perceived roles for self-tests and clinic-based testing, and the importance of integrating HIV self-tests within broader sexual health routines. CONCLUSIONS: Although GBM see a distinct role for HIV self-testing, its rollout will likely result in missed opportunities for clinic-based STI testing and education for some GBM, particularly among younger and less-recently tested GBM. Convenient, non-clinic-based approaches to STI testing are needed alongside support platforms to maximize the benefits of HIV self-testing within comprehensive sexual health routines.

Outcomes of the CT2 study: A 'one-stop-shop' for community-based hepatitis C testing and treatment in Yangon, Myanmar.

BACKGROUND: With the advent of low-cost generic direct-acting antivirals (DAA), hepatitis C (HCV) elimination is now achievable even in low-/middle-income settings. We assessed the feasibility and effectiveness of a simplified clinical pathway using point-of-care diagnostic testing and non-specialist-led care in a decentralized, community-based setting. METHODS: This feasibility study was conducted at two sites in Yangon, Myanmar: one for people who inject drugs (PWID), and the other for people with liver disease. Participants underwent on-site rapid anti-HCV testing and HCV RNA testing using GeneXpert(R) . General practitioners determined whether participants started DAA therapy immediately or required specialist evaluation. Primary outcome measures were progression through the HCV care cascade, including uptake of RNA testing and treatment, and treatment outcomes. FINDINGS: All 633 participants underwent anti-HCV testing; 606 (96%) were anti-HCV positive and had HCV RNA testing. Of 606 tested, 535 (88%) were RNA positive and had pre-treatment assessments; 30 (6%) completed specialist evaluation. Of 535 RNA positive participants, 489 (91%) were eligible to initiate DAAs, 477 (98%) completed DAA therapy and 421 achieved SVR12 (92%; 421/456). Outcomes were similar by site: PWID site: 91% [146/161], and liver disease site: 93% [275/295]). Compensated cirrhotic patients were treated in the community; they achieved an SVR12 of 83% (19/23). Median time from RNA test to DAA initiation was 3 days (IQR 2-5). CONCLUSIONS: Delivering a simplified, non-specialist-led HCV treatment pathway in a decentralized community setting was feasible in Yangon, Myanmar; retention in care and treatment success rates were very high. This care model could be integral in scaling up HCV services in Myanmar and other low- and middle-income settings.

A mobile phone application for malaria case-based reporting to advance malaria surveillance in Myanmar: a mixed methods evaluation.

BACKGROUND: To achieve malaria elimination in the Greater Mekong Subregion, including Myanmar, it is necessary to ensure all malaria cases are detected, treated, and reported in a timely manner. Mobile phone-based applications for malaria reporting, case management, and surveillance implemented at a community-level may overcome reporting limitations associated with current paper-based reporting (PBR), but their effectiveness in this context is unknown. METHODS: A mixed methods evaluation study was undertaken to determine the effectiveness of a national Malaria Case-Based Reporting (MCBR) mobile phone application in improving malaria case reporting compared to the existing PBR reporting system in Myanmar. Methods included secondary analysis of malaria case report data, questionnaires, focus group discussions and field observations of community volunteers, interviews and direct observations of malaria programme stakeholders, and cost analysis. Using a combination of these approaches the following areas were investigated: data quality and completeness, data access and usage, capacity for timely reporting, the acceptability, functionality, and ease of use of the application and facilitators and barriers to its use, and the relative cost of MCBR compared to the PBR system. RESULTS: Compared to PBR, MCBR enabled more accurate and complete data to be reported in a much timelier manner, with 63% of MCBR users reporting they transmit rapid diagnostic test outcomes within 24 h, compared to 0% of PBR users. MCBR was favoured by integrated community malaria volunteers and their supervisors because of its efficiency. However, several technical and operational challenges associated with internet coverage, data transmission, and e-literacy were identified and stakeholders reported not being confident to rely solely on MCBR data for programmatic decision-making. CONCLUSIONS: Implementation of MCBR provided timely and accurate data for malaria surveillance. Findings from this evaluation study will enable the optimization of an application-based reporting system for malaria monitoring and surveillance in the Greater Mekong Subregion and advance systems to track progress towards, and certify, the achievement of malaria elimination targets.

Real-world monitoring progress towards the elimination of hepatitis C virus in Australia using sentinel surveillance of primary care clinics; an ecological study of hepatitis C virus antibody tests from 2009 to 2019.

To achieve the elimination of the hepatitis C virus (HCV), sustained and sufficient levels of HCV testing is critical. The purpose of this study was to assess trends in testing and evaluate the effectiveness of strategies to diagnose people living with HCV. Data were from 12 primary care clinics in Victoria, Australia, that provide targeted services to people who inject drugs (PWID), alongside general health care. This ecological study spanned 2009-2019 and included analyses of trends in annual numbers of HCV antibody tests among individuals with no previous positive HCV antibody test recorded and annual test yield (positive HCV antibody tests/all HCV antibody tests). Generalised linear models estimated the association between count outcomes (HCV antibody tests and positive HCV antibody tests) and time, and χ2 test assessed the trend in test yield. A total of 44 889 HCV antibody tests were conducted 2009-2019; test numbers increased 6% annually on average [95% confidence interval (CI) 4-9]. Test yield declined from 2009 (21%) to 2019 (9%) (χ2P = <0.01). In more recent years (2013-2019) annual test yield remained relatively stable. Modest increases in HCV antibody testing and stable but high test yield within clinics delivering services to PWID highlights testing strategies are resulting in people are being diagnosed however further increases in the testing of people at risk of HCV or living with HCV may be needed to reach Australia's HCV elimination goals.

Modelling the impact of relaxing COVID-19 control measures during a period of low viral transmission.

OBJECTIVES: To assess the risks associated with relaxing coronavirus disease 2019 (COVID-19)-related physical distancing restrictions and lockdown policies during a period of low viral transmission. DESIGN: Network-based viral transmission risks in households, schools, workplaces, and a variety of community spaces and activities were simulated in an agent-based model, Covasim. SETTING: The model was calibrated for a baseline scenario reflecting the epidemiological and policy environment in Victoria during March-May 2020, a period of low community viral transmission. INTERVENTION: Policy changes for easing COVID-19-related restrictions from May 2020 were simulated in the context of interventions that included testing, contact tracing (including with a smartphone app), and quarantine. MAIN OUTCOME MEASURE: Increase in detected COVID-19 cases following relaxation of restrictions. RESULTS: Policy changes that facilitate contact of individuals with large numbers of unknown people (eg, opening bars, increased public transport use) were associated with the greatest risk of COVID-19 case numbers increasing; changes leading to smaller, structured gatherings with known contacts (eg, small social gatherings, opening schools) were associated with lower risks. In our model, the rise in case numbers following some policy changes was notable only two months after their implementation. CONCLUSIONS: Removing several COVID-19-related restrictions within a short period of time should be undertaken with care, as the consequences may not be apparent for more than two months. Our findings support continuation of work from home policies (to reduce public transport use) and strategies that mitigate the risk associated with re-opening of social venues.

Assessing the feasibility, acceptability and impacts of an education program on hepatitis B testing uptake among ethnic Chinese in Australia: results of a randomised controlled pilot study.

BACKGROUND: In Australia, Chinese migrants are among the populations most affected by hepatitis B virus (HBV) infection but often experience late diagnosis or access to clinical care. This study aims to explore approaches to increase HBV testing in Australia's Chinese community and inform evaluation planning, specifically to i) assess the feasibility and acceptability of HBV educational programs, and ii) compare HBV testing uptake in people receiving a tailored education resource focussing on liver cancer prevention compared with a standard HBV education package. METHODS: This is a pre-post mixed-methods pilot and feasibility study. People of Chinese ethnicity and unsure of their HBV infection or immunity status were recruited from ten community sites in Melbourne, Australia in 2019-2020. Participants were randomised to receive an education package (comprised of a leaflet and in-person one-on-one educational session) with a focus on either 1) standard HBV-related information, or 2) liver cancer prevention. Participants completed a baseline questionnaire prior to receiving the intervention and were followed up at 6 months' time for a questionnaire and an opt-in semi-structured interview. Primary study outcomes included feasibility of study procedures, measured by recruitment, participation, and retention rates; acceptability of the education program assessed by acceptability scores; and HBV testing uptake rate in each arm. Secondary outcomes include HBV-related knowledge change, assessed by pre-post comparison; and factors affecting participants' testing behaviour analysed using qualitative data. RESULTS: Fifty-four participants received an education package; baseline and follow-up data from 33 (61%) were available. The study procedures of recruitment and retention were feasible; the acceptability of the education program was moderate with improved HBV-related knowledge observed. Four participants self-reported being tested: one (1/15, 7%) in the standard HBV information group and three (3/18, 17%) in the liver cancer prevention information group. Factors identified as affecting testing included perceived relevance and seriousness of HBV, healthcare access and costs of testing, and perceptions of the role of primary care providers in HBV-related care. CONCLUSION: A tailored education program targeting ethnic Chinese in Australia was feasible with moderate acceptability. A larger study is required to determine if a liver cancer prevention message would improve HBV testing uptake in Chinese community than standard HBV education message. Supports from healthcare providers, community-based testing programs, and public health education programs are likely needed to motivate diagnostic testing among Chinese people at risk of HBV infection.
