Community acceptance and implementation of HIV prevention interventions for injection drug users

In 1997, the National Institutes of Health (NIH) reviewed evidence of the effectiveness of HIV prevention programs for injection drug users (IDUs) and recommended that three types ofinterventions be implemented to prevent transmission of HIV among IDUs: 1) community-based outreach, 2) expanded syringe access (including needle exchange programs [NEP] and pharmacy sales), and 3) drug treatment. Progress on increasing the acceptance and feasibility of implementing these programs has been made at the national level, but their implementation has been varied at the local level.Understanding the conditions under which communities accept and implement interventions can help guide effective strategies to foster the implementation of these interventions in areas where programs do not currently exist

Past-year prevalence of prescription opioid misuse among those 11 to 30

AbstractBackgroundThere are high levels of prescription and consumption of prescription opioids in the US. Misuse of prescription opioids has been shown to be highly correlated with prescription opioid-related morbidity and mortality including fatal and non-fatal overdose. We characterized the past-year prevalence of prescription opioid misuse among those 11–30years of age in the US.MethodsA systematic review and meta-analysis were carried out following a published protocol and PRISMA guidelines. We searched electronic databases; reports were eligible if they were published between 1/1/1990–5/30/2014, and included data on individuals 11–30years of age from the US. Study quality was assessed using the Newcastle-Ottawa Scale.ResultsA total of 3211 abstracts were reviewed for inclusion; after discarding duplicates and identifying non-eligible reports, a total of 19 unique reports, providing 34 estimates, were included in the final systematic review and meta-analysis. The range of past-year prescription opioid misuse prevalence the reports was 0.7%–16.3%. An increase in prevalence of 0.4% was observed over the years of data collection.ConclusionsThis systematic review and meta-analysis found a high prevalence of past-year prescription opioid misuse among individuals 11–30years of age. Importantly, we identified an increase in past-year prevalence 1990–2014. Misuse of prescription opioids has played an important role in national increases of fatal and non-fatal drug overdose, heroin use and injection, and HIV and HCV infection among young people. The observed high and increasing prevalence of prescription opioid misuse is an urgent public health issue

Stigmatization of Newly Emerging Infectious Diseases: AIDS and SARS

Objectives. We assessed relationships between sociodemographic characteristics and mental health status and knowledge of, being worried about, and stigmatization of 2 emerging infectious diseases: AIDS and SARS. Methods. We conducted a random-digit-dialed survey of 928 residents of the New York City metropolitan area as part of a study of the effects of the September 11, 2001, terrorist attacks. Questions added for this study concerned respondents’ knowledge of, worry about, and support of stigmatizing actions to control AIDS and SARS. Results. In general, respondents with greater personal resources (income, education, social support) and better mental health status had more knowledge, were less worried, and were less likely to stigmatize. This pattern held for both AIDS and SARS. Conclusions. Personal resources and mental health factors are likely to influence the public’s ability to learn about, rationally appraise the threat of, and minimize stigmatization of emerging infectious diseases such as AIDS and SARS.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/40384/2/Des Jarlais_Stigmatization of Newly Emerging Infectious Diseases_2006.pd

Social Factors Associated with AIDS and SARS

We conducted a survey of 928 New York City area residents to assess knowledge and worry about AIDS and SARS. Specific sociodemographic groups of persons were more likely to be less informed and more worried about contracting the diseases.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/40253/2/Des Jarlais_Social Factors Associated with AIDS_2005.pd

Updating the Infection Risk Reduction Hierarchy: Preventing Transition into Injection

Current approaches to prevention of blood-borne infections in injection drug users include referral to drug abuse treatment, access to sterile syringes, bleach disinfection of injection equipment, and education about not sharing equipment. However, rates of some blood-borne infections (e.g., hepatitis C virus) remain elevated among injection drug users, especially early after initiation into injection drug use. With lower infection rates in noninjectors and transition into injection drug use occurring most commonly among these noninjectors, prevention of transition into injection drug use as an additional step to reduce risk for acquisition and transmission of blood-borne infections merits closer attention.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/40275/2/Vlahov_Updating the Infection Risk Reduction Hierarchy_2004.pd

Positive deviance control-case life history: a method to develop grounded hypotheses about successful long-term avoidance of infection

Abstract Background Prevalence rates for long-term injection drug users in some localities surpass 60% for HIV and 80% for HCV. We describe methods for developing grounded hypotheses about how some injectors avoid infection with either virus. Methods Subjects: 25 drug injectors who have injected drugs 8 – 15 years in New York City. 17 remain without antibody to either HIV or HCV; 3 are double-positives; and 5 are positive for HCV but not HIV. "Staying Safe" methodology compares serostatus groups using detailed biographical timelines and narratives; and information about how subjects maintain access to physical resources and social support; their strategies and tactics to remain safe; how they handle problems of addiction and demands by drug dealers and other drug users; and how their behaviors and strategies do or do not become socially-embedded practices. Grounded theory and life-history analysis techniques compare and contrast doubly-uninfected with those infected with both viruses or only with HCV. Results Themes and initial hypotheses emerging from analyses included two master hypotheses that, if confirmed, should help shape preventive interventions: 1) Staying uninfected is not simply a question of social structure or social position. It involves agency by drug injectors, including sustained hard work and adaptation to changing circumstances. 2) Multiple intentionalities contribute to remaining uninfected. These conscious goals include balancing one's need for drugs and one's income; developing ways to avoid drug withdrawal sickness; avoiding situations where other drug users importune you to share drugs; and avoiding HIV (and perhaps HCV) infection. Thus, focusing on a single goal in prevention might be sub-optimal. Other hypotheses specify mechanisms of enacting these intentionalities. One example is finding ways to avoid extreme social ostracism. Conclusion We have identified strategies and tactics that some doubly-uninfected IDUs have developed to stay safe. Staying Safe methodology develops grounded hypotheses. These can be tested through cohort studies of incidence and prevention trials of hypothesis-based programs to help drug injectors make their injection and sexual careers safer for themselves and others. This positive deviance control-case life history method might be used to study avoiding other infections like genital herpes among sex workers.</p

Will "Combined Prevention" Eliminate Racial/Ethnic Disparities in HIV Infection among Persons Who Inject Drugs in New York City?

It has not been determined whether implementation of combined prevention programming for persons who inject drugs reduce racial/ethnic disparities in HIV infection. We examine racial/ethnic disparities in New York City among persons who inject drugs after implementation of the New York City Condom Social Marketing Program in 2007. Quantitative interviews and HIV testing were conducted among persons who inject drugs entering Mount Sinai Beth Israel drug treatment (2007–2014). 703 persons who inject drugs who began injecting after implementation of large-scale syringe exchange were included in the analyses. Factors independently associated with being HIV seropositive were identified and a published model was used to estimate HIV infections due to sexual transmission. Overall HIV prevalence was 4%; Whites 1%, African-Americans 17%, and Hispanics 4%. Adjusted odds ratios were 21.0 (95% CI 5.7, 77.5) for African-Americans to Whites and 4.5 (95% CI 1.3, 16.3) for Hispanics to Whites. There was an overall significant trend towards reduced HIV prevalence over time (adjusted odd ratio = 0.7 per year, 95% confidence interval (0.6–0.8). An estimated 75% or more of the HIV infections were due to sexual transmission. Racial/ethnic disparities among persons who inject drugs were not significantly different from previous disparities. Reducing these persistent disparities may require new interventions (treatment as prevention, pre-exposure prophylaxis) for all racial/ethnic groups
