Logics of control and self-management in narratives of people living with HIV, hepatitis C and hepatitis B

In Australia, the response to HIV, hepatitis C and hepatitis B has largely been through the constructed category of 'blood borne viruses' which treats these viruses as an interconnected set of conditions with respect to their mode of transmission. In this paper, we explore how people understand their viral infection, and compare the logics underpinning these different understandings. In-depth interviews were conducted with 61 participants who were either living with a blood borne virus or were the family members of people living with them. Our analysis reveals that the viral infection was often described as 'just a condition that needs to be managed', albeit in potentially exhausting ways. This understanding hinged upon a biomedical logic in which viral invasion was seen as causing illness and in turn necessitating biomedical intervention. In contrast, some participants with hepatitis B presented their infection as a condition unintelligible through Western biomedical logics, defined instead by symptomology - in terms of 'liver disease', and/or 'liver inflammation'. This focus on symptomology calls into question the soundness of prevention and management responses to hepatitis B based in biomedical logics and reveals the extent to which living with a virus involves multiple, sometimes incompatible, cultural logics. The different logics underpinning HIV, hepatitis C and hepatitis B reveal shortcomings of framing these viruses together as a coherent single construct.

HIV diagnosis period influences ART initiation: findings from a prospective cohort study in China

Background

We estimated the predictive effects of ART-related perceptions on the actual ART uptake behavior among ART naïve PLWH stratified by different time of HIV diagnosis under the new strategy.

Methods

A prospective cohort study was conducted among ART naïve PLWH in Guangzhou, China from June 2016 to June 2017. Cox regression model was used to evaluate the predictive effects of ART-related perceptions on ART initiation among PLWH stratified by different timepoint of HIV diagnosis (i.e., before or after the update of the new treatment policy).

Results

Among 411 participants, 150 and 261 were diagnosed before (pre-scaleup group) and after (post-scaleup group) the implementation of the new strategy, respectively. The ART initiation rate in the post-scaleup group (88.9%) was higher than that in the pre-scaleup group (73.3%) (p < 0.001). A significant difference of mean score was detected in each HBM construct between pre- and post-scaleup groups (p < 0.05). After adjusting for significant background variables, among all participants, only the self-efficacy [adjusted HR (HRa) = 1.23, 95% CI 1.06 to 1.43, p = 0.006], has a predictive effect on ART initiation; in pre-scaleup group, all constructs of HBM-related ART perceptions were predictors of ART initiation (HRa = 0.71 to 1.83, p < 0.05), while in post-scaleup group, no significant difference was found in each construct (p > 0.05).

Conclusions

The ART initiation rate was high particularly among participants who diagnosed after the new treatment strategy. The important role of the time of HIV diagnosis on ART initiation identified in this study suggested that future implementation interventions may consider to modify the ART-related perceptions for HIV patients who diagnosed before the implementation of the new ART strategy, while expand the accessibility of ART service for those who diagnosed after the implementation of the new strategy.

Comparing Australian gay and bisexual men with undiagnosed and recently diagnosed HIV infection to those in the National HIV Registry

Background Gay and bisexual men (GBM) with recent HIV infection are a key population to inform HIV-prevention. The National HIV Registry (NHR) provides details about all individuals diagnosed with HIV, but it is unclear how.

METHODS

Basic sociodemographic characteristics of GBM in the NHR who were diagnosed between 2010 and 2014 were compared with three samples of GBM: men with undiagnosed HIV infection from the Community-Based Study of Undiagnosed HIV and Testing (COUNT) study of HIV prevalence and undiagnosed infection that was conducted during 2013-14; men in the Australian Gay Community Periodic Surveys (GCPS) who were diagnosed with HIV between 2010 and 2014; and men in the HIV Seroconversion Study (SCS) who were also diagnosed in those years.

RESULTS

The NHR identified 3629 men who reported male-to-male sex as the exposure risk for their diagnosis between 2010 and 2014. COUNT identified 19 (8.9% of all men who tested HIV positive) men as having undiagnosed HIV. In the GCPS sample, 185 (2.5%) reported being diagnosed with HIV in 2010-14. In total, 367 men in the SCS received their diagnosis during 2010-14. The mean age of men in the NHR (36.8 years) was similar to that in GCPS (36.3 years) and SCS (35.1 years), while undiagnosed men in COUNT were younger (32.6 years), with no other significant differences between the samples.

CONCLUSIONS

The undiagnosed men were somewhat younger than diagnosed men. To achieve earlier diagnosis of new HIV infections, improved HIV testing frequency is needed among younger men.

Factors affecting the decision to initiate antiretroviral therapy in the era of treatment-as-prevention: synthesis of evidence from qualitative research in high-income settings

The emergence of treatment-as-prevention has made early initiation of antiretroviral treatment (ART) a "universal" policy. This review synthesizes qualitative research findings on barriers and facilitators of ART initiation in Organization for Economic Co-operation and Development (OECD) countries published since 2010. Ten articles describing seven research studies were included in the review. Findings confirmed ART initiation as a complicated process involving careful deliberation of the personal risks and benefits of treatment within the broader contexts of everyday life for people living with HIV (PLHIV). They also highlight interpersonal dynamics and concern for the public as increasingly important factors in shaping the decision to initiate treatment. The review provides valuable information for understanding treatment behaviour and maximizing treatment options brought forth by new biomedical advances.

Not so different? Comparison of risk profile of gay men who acquired HIV while travelling with those who acquired HIV in Australia

ISSUE ADDRESSED

Many countries now identify HIV and international mobility as a priority issue within a global and shared epidemic, including Australia. To support health promotion in this complex area, we investigated recent HIV infections that occurred among Australian gay men while travelling and compared to HIV infections that occurred in Australia.

METHODS

446 gay men recently diagnosed with HIV completed an on-line survey regarding the high risk event (HRE) where they believed that they acquired HIV. Those who acquired HIV while in their usual place of residence (308 men), those who were travelling within Australia (59 men), and those who were travelling overseas (79 men) were compared.

RESULTS

Those who acquired HIV while overseas had very similar risk profiles, sexual behaviour, and made similar assumptions about their partners and their own HIV status, as those who acquired HIV in Australia. Only HIV status disclosure at the HRE differed across locations (P = .030). Three quarters (74.7%) of the men who acquired HIV while overseas were not diagnosed until they returned to Australia.

CONCLUSIONS

Our findings challenge the idea that there are necessarily differences in behaviour and assumptions for HIV transmission in Australia and overseas. However, the men travelling may be in communities where HIV status is less commonly disclosed, and where HIV prevalence is higher. SO WHAT?: A deeper understanding of contextual factors may be required for HIV prevention and health promotion strategies targeting gay men travelling to locations with different cultural, HIV prevalence, and HIV testing considerations. This would also identify opportunities for new tools such as Pre-Exposure Prophylaxis and self-testing.

Impact of Peer Support on Behavior Change Among Newly Diagnosed Australian Gay Men

INTRODUCTION

Treatment as prevention relies on early uptake of HIV treatment, but onward transmission during primary HIV infection may be affected by changes in sexual risk behavior after diagnosis. What factors are associated with these changes in sexual risk behavior among gay and bisexual men?

METHODS

We surveyed gay and bisexual men recently diagnosed with HIV about changes to their sexual behavior since their diagnosis. In 2008-2010, 263 men described their sexual behavior during the 4 weeks before, and during the 4 weeks after, their HIV diagnosis. In 2010-2015, 301 men reported how they had changed their sexual behavior since their HIV diagnosis.

RESULTS

During 2008-2010, 26.6% engaged in condomless anal intercourse with non-HIV-positive casual partners during the 4 weeks before diagnosis, and 9.7% did so during the 4 weeks after diagnosis (P < 0.001). Only peer support from other people with HIV was associated with this change in behavior (OR = 1.42; 95% confidence interval = 1.07 to 1.88; P = 0.014). Peer support was also associated with partner reduction after diagnosis (P = 0.010). During 2010-2015, 31.9% reported that they had increasingly disclosed their HIV status to sex partners since their diagnosis, and 74.1% reported having reduced the number of men with whom they had sex. Peer support was associated with both these changes in behavior (P = 0.003 and P = 0.015, respectively).

CONCLUSIONS

The risk of onward transmission is likely to be less affected by immediate versus early treatment than it is by earlier diagnosis and peer support for those newly diagnosed with HIV. Enhanced peer support may further reduce the likelihood of onward transmission after diagnosis.

Motivations and Barriers to Treatment Uptake and Adherence Among People Living with HIV in Australia: A Mixed-Methods Systematic Review

In Australia, approximately 30% of people diagnosed with HIV are not accessing treatment and 8% of those receiving treatment fail to achieve viral suppression. Barriers limiting effective care warrant further examination. This mixed-methods systematic review accessed health and social sector research databases between November and December 2015 to identify studies that explored the perspective of people living with HIV in Australia. Articles were included for analysis if they described the experiences, knowledge, attitudes and beliefs, in relation to treatment uptake and adherence, published between January 2000 and December 2015. Quality appraisal utilised the Mixed Methods Appraisal Tool Version 2011. Seventy-two studies that met the inclusion criteria were reviewed. The interplay of lack of knowledge, fear, stigma, physical, emotional and social issues were found to negatively impact treatment uptake and adherence. Strategies targeting both the individual and the wider community are needed to address these barriers.

Use of antiretroviral treatment among people living with HIV in Australia between 1997 and 2012

Current international targets aim for 90% of people diagnosed with HIV to be on antiretroviral treatment (ART). This paper aims to identify sociodemographic and attitudinal factors associated with ART non-use over time in three samples of Australian people living with HIV (PLHIV). Data for this paper were derived from an Australian cross-sectional survey of PLHIV that was repeated at three different time points: 1997, 2003, and 2012. There were approximately 1000 respondents to each survey (n = 3042 in total). The survey included approximately 250 items related broadly to health and well-being, ART use, and attitudes towards ART use. Univariate and multivariate logistic regression analyses were used. While the proportion of participants using ART increased between 1997 and 2012 (78.8-87.6%, p < .001), there was a decrease between 1997 and 2003 to 70.6% (p < .001). Factors linked to ART non-use remained steady over those 15 years. In all cohorts, people less likely to be using ART were younger and had a more recent diagnosis of HIV. In 2003 and 2012, people in full-time employment were less likely to be using ART, while those whose main source of income was a pension or social security were more likely to be using ART. Multivariate models showed that, at each time point, a belief in the health benefits of delayed ART uptake was associated with non-use. These findings suggest that there may be barriers to ART uptake that have persisted over time despite changes to clinical guidelines that now encourage early uptake.

Understanding Concerns About Treatment-as-Prevention Among People with HIV who are not Using Antiretroviral Therapy

The use of antiretroviral therapy to prevent HIV transmission is now advocated in many settings, yet little research has documented the views of people with HIV. Semi-structured interviews were conducted in Australia between 2012 and 2014 with 27 HIV-positive people not using treatment at the time of interview. Thematic analysis of views on treatment-as-prevention found that while many participants recognised potential prevention benefits, only a minority was in support of initiating treatment solely to achieve those benefits. A range of uncertain or critical views were expressed regarding who would benefit, risk reduction, and changing treatment norms. Participants resisted responsibility narratives that implied treatment should be used for the public good, in favour of making considered decisions about their preferred approach to managing HIV. Engaging communities in dialogue and debate regarding the risks and benefits of treatment will be critical if this new prevention strategy is to engender public trust.

'Not Until I'm Absolutely Half-Dead and Have To:' Accounting for Non-Use of Antiretroviral Therapy in Semi-Structured Interviews with People Living with HIV in Australia

Current debates regarding the use of antiretroviral therapy (ART) to promote both individual- and population-level health benefits underscore the importance of understanding why a subpopulation of people with diagnosed HIV and access to treatment choose not to use it. Semi-structured interviews were conducted between 2012 and 2014 with 27 people living with HIV in Australia who were not using ART at the time of interview. Analytic triangulation permitted an appreciation of not only the varied personal reasons for non-use of treatment, but also underlying views on HIV treatment, and the ideal conditions imagined necessary for treatment initiation. Policy goals to increase the number of people with HIV using ART must recognize the diverse explanations for non-use of ART, which include concerns about the various impacts of committing to lifelong pharmaceutical treatment use. Our research identified distinctive subgroups among people who are not using antiretroviral therapy, with a range of individual and social needs that may affect treatment decisions. These findings challenge assumptions about treatment non-use in resource-rich settings, revealing persistent consumer fears about the potent and unknown effects of HIV medications that deserve greater recognition in policy debate on treatment uptake.
