“…First, our assessment of drug use was based on patient self-reports and social desirability bias cannot be excluded. Nevertheless, the validity and reliability of self-reports on active drug use using the OTI have already been established in many studies which used similar methods to our own (Darke, 1998;Greenfield et al, 1995), as well as in a previous study in which we documented a high level of agreement between self-reported heroin use and morphine detection in urine (Messiah et al, 2001). Second, reporting bias related to the relationship with one's physician is possible.…”

“…Such recall bias is especially likely when discussing needle and sexual partnerships with HIV-positive individuals during the risk interval. Self-reported behaviour from drug users has been evaluated in treatment programmes where as much as 50% of reported behaviour change has been called into question by checking with objective evaluation tools such as urinalysis 44 . However, studies where an in-depth interview is employed, as in the present study, report higher rates of accuracy than cursory clinical questionnaires 45 .…”

To identify determinants of HIV seroconversion among injection drug users (IDUs) during a period of rising prevalence, a case-control investigation was conducted. Cases were IDUs with a new positive test after 1 January 1994, and a negative test within the prior 18 months. Controls required 2 negative tests during the same period. Subjects completed a questionnaire on demographic, psychosocial, and behavioural factors. Eighty-nine cases and 192 controls were similar with respect to gender, age, ethnicity and inter-test interval. Multivariate analyses of events during the inter-test interval showed borrowing syringes (adj. OR = 2.96; P < 0.006), unstable housing (adj. OR = 2.01; P = 0.03) and injecting > or = 4 times daily (adj. OR = 1.71; P = 0.06) to be independently associated with seroconversion. Protective associations were demonstrated for sex with opposite gender (adj. OR = 0.36; P = 0.001) and tetrahydrocannabinol use (adj. OR = 0.41; P = 0.001). There is a need to evaluate programmes dealing with addiction, housing and the social underpinnings of risk behaviours in this population.

“…Logically, those who drop out of treatment and then return are more likely to have gone back to injecting and consequently had greater potential for exposure to HIV than those who remained in treatment. Previous studies found that interruptions to methadone treatment were associated with increased prevalence of injecting drugs and sharing syringes (24, 25), resulting in an increased risk of new HIV infection. Findings such as this reinforce recommendations to provide HIV risk reduction counseling, including messages about safe injecting, to IDUs at the time of MMTP admissions (26, 27).…”

Background Taiwan has a growing HIV/AIDS epidemic that has recently shifted to an increase among injection drug users (IDUs). This study aimed to measure the prevalence and incidence and identify correlates of HIV infection among IDUs in a large methadone maintenance treatment program (MMTP) in Taipei, Taiwan. Methods Data from intake interviews and HIV testing completed by IDUs upon admission to the Taipei City Hospital MMTP in 2007-2010 were included in this analysis. HIV testing was repeated semi-annually among maintained clients who were HIV-negative at admission. Results Of 1,444 IDUs admitted, 85.9% were male, median age was 40 years, and mean years of injecting was 14.3 (range: 1-64). The prevalence of HIV, HCV, and HIV/HCV co-infection was 13.4%, 91.1%, and 13.2%, respectively. In multivariable analysis, HIV infection was associated with sharing syringes during the 6 months prior to admission (OR=14.76, 95% CI 10.31-21.13), homelessness (OR=6.46, 95% CI1.49-28.00), and lifetime number of MMTP admissions (OR=1.76, 95% CI 1.30-2.38) and times incarcerated (OR=1.10, 95% CI1.03-1.18). HIV seroincidence was 1.15/100 person-years at risk (95% CI 0.62-8.77/100 PY) among IDUs who were HIV-negative at first admission. Conclusions Taiwanese IDUs in MMTP have a high HIV prevalence, which was associated with syringe sharing and other factors related to social marginalization. Our findings highlight the importance of harm reduction programs, including syringe exchange, along with HIV-prevention education.
