Interest in using rectal microbicides among Australian gay men is associated with perceived HIV vulnerability and engaging in condomless sex with casual partners: results from a national survey.

OBJECTIVE: We assessed interest in using rectal microbicides to prevent HIV transmission among gay men in Australia. METHODS: A national online survey was conducted in 2013. Interest in using rectal microbicides was measured on a seven-item scale (α=0.81). Factors independently associated with greater interest in using a microbicide were identified using multivariate logistic regression. RESULTS: Data were collected from 1223 HIV-negative and untested men. Mean age was 31.3 years (SD=10.8, range 18-65); 77% were born in Australia and 25% reported any condomless anal sex with a casual partner in the previous 6 months. Overall, there was moderate interest in using rectal microbicides (M=3.33, range 1-5). In multivariate analysis, greater interest in using microbicides was independently associated with being born outside Australia (adjusted OR (AOR)=1.59; p=0.009), greater self-perceived likelihood of becoming HIV positive (AOR=3.40; p<0.001), less uncertainty about the efficacy of microbicides (AOR=0.65; p=0.009), any condomless anal sex with casual partners in the previous 6 months (AOR=1.78; p=0.03) and ever having received postexposure prophylaxis (AOR=1.53; p=0.04). Interest in using microbicides was not associated with age, number of male sex partners or the HIV status of regular male partners. CONCLUSIONS: Interest in using rectal microbicides was associated with self-perceived vulnerability to HIV, engaging in sexual practices that increase the risk of HIV acquisition and less uncertainty about the efficacy of microbicides. There appears to be a group of men who would benefit from, and are highly motivated to use, a rectal microbicide product.

Evolving views and practices of antiretroviral treatment prescribers in Australia.

OBJECTIVE: To examine whether there have been recent changes in Australian antiretroviral treatment (ART) prescribers' perceptions and practices relating to early ART initiation, which was defined as commencing ART when a patient's CD4+ T-cell count approaches 500 cells/mm3 or immediately after a patient is diagnosed with HIV. DESIGN, PARTICIPANTS AND SETTING: Self-completed, anonymous, cross-sectional surveys, targeting all ART prescribers in Australia, were conducted online in 2012 and 2013. The surveys included questions on prescriber factors, CD4+ T-cell count at which prescribers would most strongly recommend ART initiation, and perceived patient characteristics that could change prescribers' practices of early initiation of ART. MAIN OUTCOME MEASURES: Proportions of ART prescribers recommending early ART initiation. RESULTS: We analysed responses from 108 participants in 2012 and 82 participants in 2013. In both years, more male than female prescribers participated. The median age of participants was 49 years in 2012 and 50 years in 2013. In both rounds, over 60% had more than 10 years' experience in treating HIV-positive patients. More prescribers in 2013 stated that they would most strongly recommend early ART initiation compared with those in 2012 (50.0% [95% CI, 38.7%-61.3%] v 26.9% [95% CI, 18.8%-36.2%]; P=0.001). The prescribers' primary concern was more about individual patient than public health benefit. Out of 824 patients for whom ART was initiated, as reported by prescribers in 2013, only 108 (13.1% [95% CI, 10.9%-15.6%]) were given ART primarily to prevent onward HIV transmission. The number of patients for whom ART was initiated was significantly associated with prescribers' HIV caseload even after adjusting for prescriber type (adjusted odds ratio, 1.73 [95% CI, 1.47-2.03]; P<0.001); of the 37 who had initiated ART for 10 or more patients, 29 had a high HIV caseload. In 2013, 60 prescribers (73.2% [95% CI, 62.2%-82.4%]) reported that they routinely recommended ART to treatment-naive, asymptomatic patients with a CD4+ T-cell count of 350-500 cells/mm3. CONCLUSION: Our findings show increasing acceptance of and support for early ART initiation primarily as treatment and not as prevention.

No ordinary mainstream illness: how HIV doctors perceive the virus.

Research has shown that social representations of HIV can constitute barriers to health workers' willingness to provide HIV care. Considering a growing shortage in the HIV primary workforce in Western countries, we examine how HIV is perceived today by doctors involved in its care. In 1989 Sontag predicted that once the virus became better understood and treatable, the dehumanizing meanings that defined the early epidemic would vanish and HIV would turn into an ordinary illness. However, research shows that HIV still carries stigma, including in the health care sector. Drawing on qualitative interviews, we found that HIV doctors in Australia perceived HIV as a far-from-ordinary chronic illness because of its extraordinary history and its capacity to extend in multiple clinical and social directions. These rarely explored perspectives can contribute to the social reframing of HIV and to strategies to build a dedicated HIV workforce in Australia and elsewhere.

Between individual agency and structure in HIV prevention: understanding the middle ground of social practice.

When HIV prevention targets risk and vulnerability, it focuses on individual agency and social structures, ignoring the centrality of community in effective HIV prevention. The neoliberal concept of risk assumes individuals are rational agents who act on information provided to them regarding HIV transmission. This individualistic framework does not recognize the communities in which people act and connect. The concept of vulnerability on the other hand acknowledges the social world, but mainly as social barriers that make it difficult for individuals to act. Neither approach to HIV prevention offers understanding of community practices or collective agency, both central to success in HIV prevention to date. Drawing on examples of the social transformation achieved by community action in Australia and Brazil, this article focuses on this middle ground and its role in effective HIV prevention.

HIV-negative and HIV-positive gay men's attitudes to medicines, HIV treatments and antiretroviral-based prevention.

We assessed attitudes to medicines, HIV treatments and antiretroviral-based prevention in a national, online survey of 1,041 Australian gay men (88.3% HIV-negative and 11.7% HIV-positive). Multivariate analysis of variance was used to identify the effect of HIV status on attitudes. HIV-negative men disagreed with the idea that HIV drugs should be restricted to HIV-positive people. HIV-positive men agreed and HIV-negative men disagreed that taking HIV treatments was straightforward and HIV-negative men were more sceptical about whether HIV treatment or an undetectable viral load prevented HIV transmission. HIV-negative and HIV-positive men had similar attitudes to pre-exposure prophylaxis but divergent views about 'treatment as prevention'.

HIV-negative gay men's perceived HIV risk hierarchy: imaginary or real?

HIV-related risk perceptions and risk practices among gay men have changed over time. We revisited perceived HIV risk and engagement in anal intercourse with casual partners among HIV-negative gay men who participated in one of the Sydney Gay Community Periodic Surveys (GCPS). Perceived HIV risk was assessed by a range of anal intercourse practices combined with pre-specified casual partners' HIV status and viral load levels. Perceived HIV risk forms a potential hierarchy, broadly reflecting differences in the probability of HIV transmission through various anal intercourse practices. To a lesser extent, it also varies by casual partners' HIV status and viral load. Men who had unprotected anal intercourse with casual partners (UAIC) perceived lower HIV risk than those who used condoms consistently in the 6 months prior to survey. Recognising the complex associations between risk perceptions and risk practices helps to better address challenges arising from the 'Treatment as Prevention' (TasP).

Australian prescribers' perspectives on ART initiation in the era of "treatment as prevention".

This study explores Australian prescribers' attitudes towards Treatment as Prevention (TasP) and their practices around initiating combination antiretroviral treatment (cART) for HIV. A brief online survey was conducted nationally amongst antiretroviral treatment (ART) prescribers in Australia. The sample broadly represented ART prescribers in Australia (N = 108), with 40.7% general practitioners (GPs), 25.9% sexual health clinic-based physicians and 21.3% hospital-based infectious diseases physicians. About 60% of respondents had been treating HIV-positive patients for more than 10 years. Respondents estimated that about 70-80% of all their HIV-positive patients were receiving ART. Over half of the prescribers agreed very strongly that their primary concern in recommending cART initiation was clinical benefit to individual patients rather than any population benefit. A majority of the prescribers (68.5%) strongly endorsed cART initiation before CD4+ T-cell count drops below 350 cells/mm(3), and a further 22.2% strongly endorsed cART initiation before CD4+ T-cell count drops below 500 cells/mm(3). Regarding the optimal timing of cART initiation, this study shows that prescribers in Australia in 2012 focus primarily on the benefits for their individual patients. Prescribers may need more convincing evidence of individual health benefits or increased knowledge about the population health benefits for a TasP approach to be effective in Australia.

At the coalface and the cutting edge: general practitioners' accounts of the rewards of engaging with HIV medicine.

BACKGROUND: HIV has become a chronic manageable infection in the developed world, and early and lifelong treatment has the potential to significantly reduce transmission rates in the community. A skilled and motivated HIV medical workforce will be required to achieve these health management and prevention outcomes, but concerns have been noted in a number of settings about the challenges of recruiting a new generation of clinicians to HIV medicine. METHODS: As part of a larger qualitative study of the HIV general practice workforce in Australia, in-depth interviews were conducted with 31 general practitioners accredited to prescribe HIV medications in community settings. A thematic analysis was conducted of the de-identified transcripts, and this paper describes and interprets accounts of the rewards of pursuing and sustaining an engagement with HIV medicine in general practice settings. RESULTS: The rewards of initially becoming involved in providing care to people living with HIV were described as interest and inspiration, community calling and right place, right time. The rewards which then supported and sustained that engagement over time were described as challenge and change, making a difference and enhanced professional identity. Participants viewed the role of primary care doctor with special expertise in HIV as occupying an ideal interface between the 'coalface' and the 'cutting edge', and offering a unique opportunity for general practitioners to feel intimately connected to both community needs and scientific change. CONCLUSIONS: Approaches to recruiting and retaining the HIV medical workforce should build upon the intellectual and social rewards of this work, as well as the sense of professional belonging and connection which is imbued between both doctors and patients and across the global and national networks of HIV clinicians. Insights regarding the rewards of engaging with HIV medicine may also be useful in enhancing the prospect of general practice as a career, and strengthening retention and job satisfaction among the existing general practice workforce.

Willingness to use HIV pre-exposure prophylaxis and the likelihood of decreased condom use are both associated with unprotected anal intercourse and the perceived likelihood of becoming HIV positive among Australian gay and bisexual men.

OBJECTIVES: To investigate willingness to use HIV pre-exposure prophylaxis (PrEP) and the likelihood of decreased condom use among Australian gay and bisexual men. METHODS: A national, online cross-sectional survey was conducted in April to May 2011. Bivariate relationships were assessed with χ2 or Fisher's exact test. Multivariate logistic regression analysis was performed to assess independent relationships with primary outcome variables. RESULTS: Responses from 1161 HIV-negative and untested men were analysed. Prior use of antiretroviral drugs as PrEP was rare (n=6). Just over a quarter of the sample (n=327; 28.2%) was classified as willing to use PrEP. Willingness to use PrEP was independently associated with younger age, having anal intercourse with casual partners (protected or unprotected), having fewer concerns about PrEP and perceiving oneself to be at risk of HIV. Among men who were willing to use PrEP (n=327), only 26 men (8.0%) indicated that they would be less likely to use condoms if using PrEP. The likelihood of decreased condom use was independently associated with older age, unprotected anal intercourse with casual partners (UAIC) and perceiving oneself to be at increased risk of HIV. CONCLUSIONS: The Australian gay and bisexual men the authors surveyed were cautiously optimistic about PrEP. The minority of men who expressed willingness to use PrEP appear to be appropriate candidates, given that they are likely to report UAIC and to perceive themselves to be at risk of HIV.

The role of the general practitioner in the Australian approach to HIV care: interviews with 'key informants' from government, non-government and professional organisations.

OBJECTIVES: HIV care is provided in a range of settings in Australia, but advances in HIV treatment and demographic and geographic changes in the affected population and general practitioner (GP) workforce are testing the sustainability of the special role for GPs. This paper explores how a group of 'key informants' described the role of the GP in the Australian approach to HIV care, and conceptualised the challenges currently inspiring debate around future models of care. METHODS: A thematic analysis was conducted of semistructured interviews carried out in 2010 with 24 professionals holding senior roles in government, non-government and professional organisations that influence Australian HIV care policy. RESULTS: The strengths of the role of the GP were described as their community setting, collaborative partnership with other medical and health professions, and focus on patient needs. A number of associated challenges were also identified including the different needs of GPs with high and low HIV caseloads, the changing expectations of professional roles in general practice, and barriers to service accessibility for people living with HIV. CONCLUSIONS: While there are many advantages to delivering HIV services in primary care, GPs need flexible models of training and accreditation, support in strengthening relationships with other health and medical professionals, and assistance in achieving service accessibility. Consideration of how to support the GP workforce so that care can be made available in the broadest range of geographical and service settings is also critical if systems of HIV care delivery are to be realistic and cost-effective and meet consumer needs.

The impact of HIV seroadaptive behaviors on sexually transmissible infections in HIV-negative homosexual men in Sydney, Australia.

BACKGROUND: Human immunodeficiency virus (HIV) seroadaptive behaviors, such as serosorting and strategic positioning, are being increasingly practised by homosexual men; however, their impact on sexually transmissible infections is unclear. METHODS: Participants were 1427 initially HIV-negative men enrolled from 2001 to 2004 and followed to June 2007. Participants were tested annually for anal and urethral gonorrhoea and chlamydia, herpes simplex virus, and syphilis. In addition, they reported diagnoses of these conditions, and of genital and anal warts between annual visits, and sexual risk behaviors. RESULTS: Compared with men who reported no unprotected anal intercourse (UAI), serosorting was associated with an increased risk of urethral (incidence: 6.06 vs. 3.56 per 100 person-years (PY), hazard ratio (HR) = 1.97, 95% confidence interval [CI]: 1.43-2.72) and anal (incidence 3.95 vs. 2.80 per 100 PY, HR = 1.62, 95% CI: 1.11-2.36) chlamydia. Compared with men who reported UAI with HIV nonconcordant partners, men who practised serosorting had significantly lower risk of incident syphilis (incidence 0.18 vs. 1.00 per 100 PY, HR = 0.21, 95% CI: 0.05-0.81) and urethral gonorrhoea (incidence 2.15 vs. 5.52 per 100 PY, HR = 0.61, 95% CI: 0.39-0.96). Compared with men who reported no UAI, strategic positioning was associated with an increased risk of urethral gonorrhoea (incidence 4.11 vs. 2.10 per 100 PY, HR = 1.72, 95% CI: 1.05-2.83) and chlamydia (incidence 8.71 vs. 3.56 per 100 PY, HR = 2.22, 95% CI: 1.55-3.18). Compared with men who reported receptive UAI, the incidence of anal gonorrhoea (incidence 1.48 vs. 3.83 per 100 PY, HR = 0.38, 0.20-0.74) and chlamydia (incidence 3.10 vs. 6.30 per 100 PY, HR = 0.44, 95% CI: 0.27-0.69) was significantly lower in those who practised strategic positioning. CONCLUSION: For men who reported seroadaptive behaviors, rates of some bacterial sexually transmissible infections were higher than in men who reported no UAI. However, rates were lower than for men who reported higher HIV risk behaviors.

Beyond the distinction between biomedical and social dimensions of HIV prevention through the lens of a social public health.

Developing effective HIV prevention requires that we move beyond the historical but problematic distinction between biomedical and social dimensions of HIV. The current claim that prevention has failed has led to a strong interest in the role of treatment as HIV prevention; however, the turn to "biomedical prevention," "test and treat," and "combination prevention" instances pervasive confusions about prevention. These confusions arise from a failure to realize that all HIV prevention interventions must engage with the everyday lives of people and be integrated into their social relations and social practices. We challenge the claim that prevention has failed (illustrating this with discussion of prevention in Australia, Uganda, and Zimbabwe). We explain the enduring appeal of misguided approaches to prevention by examining how 1996 can be seen as a pivotal moment in the history of the global response to HIV, a moment marked by the rise and fall of distinct biomedical and social narratives of HIV.

Does drug and alcohol use undermine concordance between doctors' assessments of major depression and patients' scores on a screening tool for depression among gay men attending general practice?

General practitioners (GPs) identify that depression can be difficult to diagnose in populations with high rates of alcohol and other drug (AOD) use. This is a particular concern with gay men who are a population known to engage in high rates of AOD use and who are vulnerable to depression. This paper uses data from 563 gay men and their GPs to describe concordance between assessments of major depression and, in particular, whether AOD use undermines concordance. Data were collected as part of a larger study of male patients and GPs at high HIV-caseload general practices in Australia. Concordance was measured by comparing patients' scores on the Patient Health Questionnaire-9 screening tool, which is based on the Diagnostic and Statistical Manual of Mental Disorders IV criteria, and GPs' ratings of the likelihood of depression for each participant. We observed high concordance between GPs' assessments of major depression and patients' scores on the PHQ-9 (79% agreement), although our analysis also suggested that concordance was better when it related to cases in which there was no depression. The high concordance observed in our study did not appear to be undermined by gay male patients' AOD use, with the exception of frequent use of crystal methamphetamine. Here, men who reported frequent use of methamphetamine were significantly less likely to have concordant assessments (adjusted odds ratio 0.3, 95% CI 0.1-0.8). Overall, GPs appear to identify depression among many of their gay male patients. While GPs should be aware of the potential complications presented by frequent crystal methamphetamine use, other AOD use may have less impact on the diagnosis of depression.

Rates of condom and non-condom-based anal intercourse practices among homosexually active men in Australia: deliberate HIV risk reduction?

OBJECTIVE: Three decades into the HIV epidemic and with the advancement of HIV treatments, condom and non-condom-based anal intercourse among gay men in resource-rich countries needs to be re-assessed. METHODS: The proportions of men engaging in a range of anal intercourse practices were estimated from the ongoing cross-sectional Gay Community Periodic Surveys in six states in Australia from 2007 to 2009. Comparisons were made between HIV-negative men, HIV-positive men with an undetectable viral load and those with a detectable viral load. RESULTS: Condoms play a key role in gay men's anal intercourse practices: 33.8% of HIV-negative men, 25.1% of HIV-positive men with an undetectable viral load and 22.5% of those with a detectable viral load reported consistent condom use with all male partners in the 6 months before the survey. Among HIV-negative men, the second largest group were men who had unprotected anal intercourse (UAI) only in the context of HIV-negative seroconcordant regular relationships. Among HIV-positive men, the second largest group was men who had UAI in casual encounters preceded by HIV status disclosure to some, but not all, casual partners. CONCLUSIONS: A minority, yet sizeable proportion, of men consistently engaged in a number of UAI practices in specific contexts, suggesting they have adopted deliberate HIV risk-reduction strategies. While it is important that HIV behavioural prevention continues to reinforce condom use, it needs to address both the challenges and opportunities of the substantial uptake of non-condom-based risk-reduction strategies.

What moves a family doctor to specialise in HIV? Interviews with Australian policy key informants.

The population of people living with HIV in Australia is increasing, requiring an expert primary care workforce to provide HIV clinical care into the future. Yet the numbers of family doctors or general practitioners (GPs) training as community-based HIV medication prescribers may be insufficient to replace those retiring, reducing hours or changing roles. We conducted semi-structured interviews between February and April, 2010, with 24 key informants holding senior roles in organisations that shape HIV-care policy to explore their perceptions of contemporary issues facing the HIV general practice workforce in Australia. Informed by interpretive description, our analysis explores how these key informants characterised GPs as being 'moved' by the clinical, professional and political dimensions of the role of the HIV general practice doctor. Each of these dimensions was represented as essential to the engagement of GPs in HIV as an area of special interest, although the political dimensions were often described as the most distinctive compared to other areas of general practice medicine. Our analysis explores how each of these dimensions contributes to shaping the contemporary culture of HIV medicine and suggests that such an approach could be useful for understanding how health professionals become engaged in other under-served areas of medical work.

Discourses of depression of Australian general practitioners working with gay men.

The data for this article are from a primary health care project on HIV and depression, in which the prevalence, nature, clinical management, and self-management of depression among homosexually active men attending high-HIV-caseload general practice clinics were investigated. One of the qualitative arms consisted of in-depth interviews with general practitioners (GPs) with high caseloads of gay men. The approach to discourse analysis was informed by Halliday's systemic functional linguistics. GPs constructed three discourses of depression: engaging with psychiatric discourse, engaging with the patient's world, and engaging with social structures. When GPs drew on the discourse of psychiatry, this discourse was positioned as only one possible construction of depression. This discourse was also contextualized in the social lives of gay men, and it was explicitly challenged and rejected. Engaging with their patients' social world was considered vital for recognizing depression in gay men. Finally, the GPs' construction of depression was inextricably linked to social disadvantage and marginalization. Depression is highly heterogeneous and constructed in terms of social relationships rather than as an independent entity that resides in the individual. There is a synergy between GPs' constructions of depression and men's experiences of depression, which differs from conventional medical views, and which enables GPs to be highly effective in dealing with the mental health issues of their gay patients.

Prevalence, incidence and risk factors for hepatitis C in homosexual men: data from two cohorts of HIV-negative and HIV-positive men in Sydney, Australia.

BACKGROUND: An increasing incidence of hepatitis C virus (HCV) infection in HIV-positive homosexual men has recently been described, but it is uncertain to what extent this reflects sexual transmission. We report prevalence, incidence and risk factors for HCV infection in community-based cohorts of HIV-negative and HIV-positive homosexual men in Sydney. METHODS: Both cohorts recruited participants using similar community-based strategies. Men underwent annual face-to-face interviews, and reported history of injecting-drug use (IDU) and sexual and other behaviours that might lead to blood contact. HCV screening was offered to consenting participants from 2001 to 2007. RESULTS: At baseline, HCV prevalence was 1.07% in the HIV-negative and 9.39% in the HIV-positive men. HCV seropositivity was strongly associated with a history of IDU in both cohorts (OR=56.18, 95% CI 12.55 to 251.5 in HIV-negative, and OR=24.46, 95% CI 5.44 to 110.0 in HIV-positive). In the HIV-negative cohort, five men seroconverted to HCV over 4412.1 person-years of follow-up, an incidence of 0.11 per 100 person-years (95% CI 0.03 to 0.26). Only one seroconverter reported IDU. Of the five, four reported sexual contact with HIV-positive men (HR=8.23, 95% CI 0.91 to 74.28), and two had an incident ulcerative sexually transmitted infection. In the HIV-positive cohort, none seroconverted over 238.1 person-years of follow-up (97.5% CI 0 to 1.54, single-sided). CONCLUSION: HCV prevalence was almost 10 times higher in HIV-positive homosexual men. Although incident HCV infection was uncommon in both cohorts, cases of non-IDU-related transmission did occur, possibly linked to sexual contact with HIV-positive men.

Prevalence, incidence and risk factors for pharyngeal gonorrhoea in a community-based HIV-negative cohort of homosexual men in Sydney, Australia.

BACKGROUND: Pharyngeal gonorrhoea is common in homosexual men and may be important in maintaining community prevalence of anogenital infections. METHODS: From 2003, all participants in the Health in Men cohort of HIV-negative homosexual men in Sydney were offered annual pharyngeal gonorrhoea screening by BD ProbeTec nucleic acid amplification (NAAT) assay with supplementary porA testing. Participants self-reported diagnoses of pharyngeal gonorrhoea made elsewhere between interviews. Detailed sexual behavioural data were collected 6-monthly. RESULTS: Among 1427 participants enrolled, 65 study-visit-diagnosed pharyngeal gonorrhoea infections were identified (incidence 1.51 per 100 person-years, 95% CI 1.19 to 1.93) of which seven infections were identified on baseline testing (prevalence 0.57%, 95% CI 0.23 to 1.17%). Almost 85% of study-visit-diagnosed pharyngeal infections occurred without concurrent anogenital gonorrhoea. The combined incidence of study-visit-diagnosed and self-reported pharyngeal gonorrhoea (n=193) was 4.45 per 100 person-years (95% CI 3.86 to 5.12). On multivariate analysis, incident infection was associated with younger age (p-trend=0.001), higher number of male partners (p-trend=0.002) and reported contact with gonorrhoea (p<0.001). Insertive oro-anal sex ('rimming') was the only sexual behaviour independently associated with incident pharyngeal gonorrhoea (p-trend=0.044). CONCLUSIONS: The majority of pharyngeal gonorrhoea occurred without evidence of concurrent anogenital infection, and the high incidence-to-prevalence ratio suggests frequent spontaneous resolution of NAAT-detected infection. The association of pharyngeal gonorrhoea with oro-anal sex indicates that a broader range of sexual practices are likely to be involved in transmission of gonorrhoea to the pharynx than previously acknowledged. Screening the pharynx of sexually active homosexual men could play a role in reducing the prevalence of anogenital Neisseria gonorrhoeae.

HIV-related discriminatory attitudes of healthcare workers in Bangladesh.

This study aimed at identifying the level of HIV-related discriminatory attitudes and related factors in a purposively-selected sample of healthcare workers (HCWs) in Bangladesh. In total, 526 HCWs from a number of hospitals and healthcare centres were interviewed using a structured questionnaire. A moderate level of discriminatory attitudes was observed. The factors associated with a high level of such attitudes among the HCWs were: high level of irrational fear about HIV and AIDS; working in teaching hospital rather than in non-teaching hospital and diagnostic centres; low level of education; and being male. The results indicate that programmes to reduce irrational fear about transmission of HIV are urgently needed.

The role of physician and nurse attitudes in the health care of injecting drug users.

In 2005, 60 health care workers were recruited through services that attract injecting drug users (IDUs) and asked to complete attitude measures regarding IDU clients. Mediation analyses indicated that conservative health care workers displayed more negative attitudes toward their IDU clients because they believe that injecting drug use is within the control of the IDU. Negative attitudes toward IDU clients, in turn, were associated with worry about IDU clients' behavior in the clinic and with beliefs that IDU clients should disclose their hepatitis C status to their health care worker. Perceptions of controllability of drug use were also associated with the belief that IDU clients' ailments were caused by their IDU status. The study's limitations are noted.
