RESUMO

BACKGROUND: People who inject drugs (PWID) experience many health problems which result in a heavy economic and public health burden. To tackle this issue, France opened two drug consumption rooms (DCRs) in Paris and Strasbourg in 2016. This study assessed their long-term health benefits, costs and cost-effectiveness. METHODS: We developed a model to simulate two fictive cohorts for each city (n=2,997 in Paris and n=2,971 in Strasbourg) i) PWID attending a DCR over the period 2016-2026, ii) PWID attending no DCR. The model accounted for HIV and HCV infections, skin abscesses and related infective endocarditis, drug overdoses and emergency department visits. We estimated the number of health events and associated costs over 2016-2026, the lifetime number of quality-adjusted life-years (QALYs) and costs, and the incremental cost-effectiveness ratio (ICER). RESULTS: The numbers of abscesses and associated infective endocarditis, drug overdoses, and emergency department visits decreased significantly in PWID attending DCRs (-77%, -69%, and -65%, respectively) but the impact on HIV and HCV infections was modest (-11% and -6%, respectively). This resulted in savings of €6.6 (Paris) and €5.8 (Strasbourg) millions of medical costs. The ICER of DRCs was €30,600/QALY (Paris) and €9,200/QALY (Strasbourg). In scenario analysis where drug consumption spaces are implemented inside existing harm reduction structures, these ICERs decreased to €21,400/QALY and €2,500/QALY, respectively. CONCLUSIONS: Our findings show that DCRs are highly effective and efficient to prevent harms in PWID in France, and advocate extending this intervention to other cities by adding drug consumption spaces inside existing harm reduction centers.

RESUMO

Participatory research can help improve addiction services. However, the superficial involvement of people with experiential knowledge runs the risk of reproducing social inequity rather than strengthening their empowerment. This article aims to present a critical analysis, co-constructed through a dialogue between people with academic and experiential knowledge, of different types of participation and collaboration undertaken over a number of years, while also examining issues raised by the professionalization or formalization of the role of people with experiential expertise in participatory research in the field of addiction. The results of this analysis have led to a co-constructed critical assessment that deals with the following themes: 1) a description of the collaborative process over time and the diverse ways in which people with experiential knowledge have been involved; 2) conceptual considerations with respect to the terms used and the identities linked to them; 3) aspects that have facilitated collaboration; 4) obstacles and challenges that were encountered. This dialogue between academic and experiential knowledge highlights the need to review institutional rules so as to better recognize the status of people with experiential knowledge involved in research. Recognition of skills related to eligibility for research positions should not be limited to academic qualifications. Experiential knowledge should be integrated into hiring processes as a recognized type of expertise.

RESUMO

Participatory health research is developing rapidly. Certain issues make the involvement of people with experiential knowledge in research both more complex and more necessary. This is the case for people who use drugs, whose knowledge rendered invisible by the illegality of drug use and the multiple ensuing forms of domination and stigmatization. The purpose of this article is to recount a particular experience of close long-term partnership between a person with experiential knowledge and an academic researcher. Based on a singular collaboration, this article sheds light on the contributions of participatory research, their social and political effects, and their limits. It shows how each stakeholder draws on the knowledge of the other to co-produce research that can help public action evolve and limit epistemic injustices. It also highlights the multiple identities present in this type of collaboration, which foster the conditions for the co-production of knowledge, and suggests ways of enabling similar collaborations with diverse groups.

RESUMO

BACKGROUND: Drug consumption rooms (DCRs) have been developed in cities with open drug scenes, with the aim to reduce drug-related harm. In Lyon, France's second-largest city, there is no distinct drug use area, which raised doubts regarding the need for a DCR. METHODS: We conducted a face-to-face survey of 264 people who use drugs (PWUDs), recruited in harm reduction or addiction treatment centers, in the streets or in squats. We assess their willingness to use a DCR, and we collected sociodemographic and medical features. Bivariable comparisons and analyses adjusted for sociodemographic parameters explored the association between willing to use a DCR and other variables, thus providing crude (ORs) and adjusted odds ratios (aORs) and 95% confidence intervals (95% CI). RESULTS: In total, 193 (73.1%) PWUDs accepted to participate (mean age 38.5 ± 9.3 years; 80.3% men). Among them, 64.2% declared willing to use a DCR. Being treatment-seeker (aOR 0.20, 95% CI [0.08-0.51]; p < 0.001) and not living alone (aOR 0.29; 95% CI [0.10-0.86], p = 0.025) were negatively associated with willing to use a DCR. By contrast, receiving precarity social insurance (aOR 4.12; 95% CI [1.86-9.14], p < 0.001), being seropositive for hepatitis C (aOR 3.60; 95% CI [1.20-10.84], p = 0.022), being cannabis user (aOR 2.45; 95% CI [1.01-5.99], p = 0.049), and reporting previous problems with residents (aOR 5.99; 95% CI [2.16-16.58], p < 0.001) or with the police (aOR = 4.85; 95% CI [1.43-16.39], p = 0.011) were positively associated. CONCLUSIONS: PWUDs, especially the most precarious ones, largely supported the opening of a DCR in Lyon, a city with no open drug scene.

RESUMO

While young adults experienced mental health challenges during the COVID-19 pandemic, little is known about how their mental health needs were subsequently met through access to mental health services (MHS). From October to December 2020, we conducted an online survey of young adults (18-29 years) living in Canada and France to investigate factors associated with unmet MHS needs. Of the 3222 participants expressing a need to access MHS (50.7% of the total sample), 58.2% in Canada and 74.8% in France reported unmet MHS needs. In both countries, those who identified as men and those who lost income due to COVID-19, were more likely to report unmet MHS needs. In Canada, participants from Quebec, those living in rural areas, and those who experienced ethno-racial discrimination had higher odds of reporting such unmet needs. Urgent investments are needed to improve access to MHS for young adults during and after the COVID-19 pandemic.

RESUMO

Drug consumption rooms (DCRs) have the potential to have a positive impact on the opioid overdose crisis. DCRs could also potentially change the political environment for public health because they can affect the distribution of responsibility for harm reduction between the individual and society by collectivizing responsibility for harm reduction through welfare regimes. The methodology is based on 2 case studies-1 in Copenhagen, Denmark, and 1 in Paris, France-about residents, people who inject drugs (PWID), and politicians' experiences of DCRs involving semidirective interviews. Denmark has a long history of harm-reduction policy, and the implementation of DCRs in Copenhagen has happened through close collaboration between local authorities and the local community. France is far more centralized and paternalistic in terms of the distribution of authority and decision-making in welfare and drug policy. Difficulties in cohabitation between local residents and PWID happened in both countries and can sometimes make public authorities hesitate to implement DCRs because of the NIMBY ("not in my backyard") phenomenon. However, the Danish and French case studies show that DCRs have the potential to become an instrument for civic cohabitation as well as to contribute to the destigmatization and health of PWID.

RESUMO

Objectives. To determine how harm reduction should be applied in low-resource countries such as Vietnam by exploring the perspectives of people who use drugs (PWUD), health care professionals, and policymakers regarding methadone treatment and harm reduction strategies. Methods. We conducted 2 qualitative studies in Vietnam between 2016 and 2021. We interviewed 62 PWUD and 22 experts in drug policy development and drug treatment programs, conducted observations at methadone clinics and harm reduction program meetings, and analyzed drug policy documents. Results. PWUD considered methadone treatment only as a transition to a drug-free life. Policymakers deemed harm reduction ineffective and continued to enforce arrest and incarceration of PWUD. Drug intervention programs are not yet geared to providing specialized services. Effective communication strategies and information on evidence-based harm reduction models are inadequate to help policymakers make the right decisions. Conclusions. Harm reduction principles have not been fully adopted in Vietnam. A harm reduction strategy based on a more humanistic approach that goes beyond a biomedicalized approach is urgently needed in Vietnam and other countries in the Global South.

RESUMO

BACKGROUND: To encourage Covid-19 vaccination, France introduced during the Summer 2021 a 'Sanitary Pass', which morphed into a 'Vaccine Pass' in early 2022. While the sanitary pass led to an increase in Covid-19 vaccination rates, spatial heterogeneities in vaccination rates remained. To identify potential determinants of these heterogeneities and evaluate the French sanitary and vaccine passes' efficacies in reducing them, we used a data-driven approach on exhaustive nationwide data, gathering 141 socio-economic, political and geographic indicators. METHODS: We considered the association between vaccination rates and each indicator at different time points: before the sanitary pass announcement (week 2021-W27), before the sanitary pass came into force (week 2021-W31) and 1 month after (week 2021-W35) and the equivalent dates for the vaccine pass (weeks 2021-W49, 2022-W03 and 2022-W07). RESULTS: The indicators most associated with vaccination rates were the share of local income coming from unemployment benefits, overcrowded households rate, immigrants rate and vote for an 'anti-establishment' candidate at the 2017 Presidential election. These associations increase over time. Consequently, living in a district below the median of such indicator decreases the probability to be vaccinated by about 30% at the end of the studied period, and this probability gradually decreases by deciles of these indicators. CONCLUSIONS: Our analysis reveals that factors related to poverty, immigration and trust in the government are strong determinants of vaccination rate, and that vaccination inequities tended to increase after the introduction of the French sanitary and vaccination passes.

RESUMO

Background: People who inject drugs are subjected to great stigmatization in many parts of the world. How they deal with stigma is closely linked to how stigma means to them. Understanding the strategies individuals employ to cope with these negative attitudes and what resources they mobilize in this process gives useful insights for clinical work and policy development. Methods: We conducted 12 months of field observation in 2017 and 2018 and 54 in-depth interviews with people who inject drugs in Haiphong, Vietnam. Grounded theory underpinned our sampling and data analysis. Results: The strategies participants used to manage stigma were both information and tension management. Many participants not only concealed their drug use but actively cultivated a pro-social image based on Vietnamese cultural virtues such as selflessness, hard work or harmonious living with others. Participants withdrew from social relationships to distance themselves from the stereotype of a money-begging drug user. They used techniques of neutralization to emphasize their good character and reframe their drug-related issues in a different light in order to negotiate their social status with their interlocutors. Conclusion: People who inject drugs endorse the same social values and aspirations as nonusers. A good support structure and resources could help them to cope more effectively with stigma.

RESUMO

BackgroundPeople who inject drugs (PWID) are frequently incarcerated, which is associated with multiple negative health outcomes.AimWe aimed to estimate the associations between a history of incarceration and prevalence of HIV and HCV infection among PWID in Europe.MethodsAggregate data from PWID recruited in drug services (excluding prison services) or elsewhere in the community were reported by 17 of 30 countries (16 per virus) collaborating in a European drug monitoring system (2006-2020; n = 52,368 HIV+/-; n = 47,268 HCV+/-). Country-specific odds ratios (OR) and prevalence ratios (PR) were calculated from country totals of HIV and HCV antibody status and self-reported life-time incarceration history, and pooled using meta-analyses. Country-specific and overall population attributable risk (PAR) were estimated using pooled PR.ResultsUnivariable HIV OR ranged between 0.73 and 6.37 (median: 2.1; pooled OR: 1.92; 95% CI: 1.52-2.42). Pooled PR was 1.66 (95% CI 1.38-1.98), giving a PAR of 25.8% (95% CI 16.7-34.0). Univariable anti-HCV OR ranged between 1.06 and 5.04 (median: 2.70; pooled OR: 2.51; 95% CI: 2.17-2.91). Pooled PR was 1.42 (95% CI: 1.28-1.58) and PAR 16.7% (95% CI: 11.8-21.7). Subgroup analyses showed differences in the OR for HCV by geographical region, with lower estimates in southern Europe.ConclusionIn univariable analysis, a history of incarceration was associated with positive HIV and HCV serostatus among PWID in Europe. Applying the precautionary principle would suggest finding alternatives to incarceration of PWID and strengthening health and social services in prison and after release ('throughcare').

RESUMO

BACKGROUND: Prisoners report much higher prevalence rates of drug use and more harmful consumption patterns than the general population. People who use drugs have above-average experiences with the criminal justice system in general, and the prison system and subsequent release situations in particular. Release from prison is associated with increased mortality rates among drug users due to the risk of overdose. The EU-funded project 'My first 48 hours out' aimed to address the gaps in continuity of care for long-term drug users in prison and upon release, with a special focus on drug user's perspectives on needs and challenges upon release. METHODS: A multi-country (Belgium, France, Germany and Portugal) qualitative study was set up to explore drug users' perceptions of drug use and risk behaviour upon prison release, experiences of incarceration and release, and strategies to avoid risks when being released. In total, 104 prisoners and recently released persons with a history of drug use participated in semi-structured interviews and focus groups discussions on these topics. RESULTS: Respondents pointed out that there are numerous challenges for people who use drugs when released from prison. Lack of stable housing and employment support were frequently mentioned, as well as complex administrative procedures regarding access to services, health insurance and welfare benefits. Besides structural challenges, individual issues may challenge social reintegration like 'old habits', mental health problems and disrupted social networks. As a result, (ex-)prisoners adopt individual strategies to cope with the risks and challenges at release. CONCLUSION: Measures to prepare prisoners for release often do not focus on the individual and specific challenges of persons who use drugs. Psychosocial and medical support need to be improved and adjusted to drug users' needs inside and outside prison. To improve the quality and continuity of care around release, the perspectives and coping strategies of people who use drugs should be used to better address their needs and barriers to treatment.

RESUMO

BACKGROUND: HIV, HBV and HCV infections continue to represent major health concerns, especially among key at-risk populations such as men who have sex with men (MSM), people who inject drugs (PWIDs), transgender women (TGW) and sex workers (SW). The objective of the ANRS-CUBE study was to evaluate the acceptability of a healthcare, community-based strategy offering a triple rapid HIV-HBV-HCV testing, and HBV vaccination, targeted at three priority groups (MSM, PWIDs and TGW/SWs), in three community centers, in the Paris area. METHODS: This longitudinal multicentric non-randomized study included all adult volunteers attending one of the three specialized community centers in Paris, between July 2014 and December 2015. HIV, HBV and HCV status and acceptability of HBV vaccination were evaluated. RESULTS: A total of 3662, MSM, 80 PWIDs and 72 TGW/SW were recruited in the three centers respectively. Acceptability of rapid tests was 98.5% in MSM and 14.9% in TGW/SWs, but could not be estimated in PWIDs since the number of users attending and the number of proposals were not recorded. User acceptability of HBV vaccination was weak, only 17.9% of the eligible MSM (neither vaccinated, nor infected) agreed to receive the first dose, 12.2% two doses, 5.9% had a complete vaccination. User acceptability of HBV vaccination was greater in PWIDs and TGW/SWs, but decreased for the last doses (66.7 and 53.3% respectively received a first dose, 24.4 and 26.7% a second dose and 6.7 and 0% a third dose). Fifty-three participants (49 MSM and 4 PWIDs) were discovered HIV positive, more than half with a recent infection. All but two HIV positive participants were linked to appropriate care in less than one month. CONCLUSIONS: Rapid HIV-HCV-HBV screening showed a very high level of acceptability among MSM. Efforts need to be made to improve immediate acceptability for HBV vaccination, especially among MSM, and follow-up doses compliance. Our results show the important role of community centers in reaching targets, often fragile, populations, while also suggesting the need to reinforce on-site human support in terms of testing and vaccination, especially when addressing PWIDs.

RESUMO

BACKGROUND: After the collapse of the Soviet Union at the beginning of the 1990s, people who inject drugs spiked in Eastern Europe. Facing local repression and an array of factors encouraging emigration, some users have migrated to France. This population now make up to a third of the patient list of some harm reduction services in Paris. This article aims to present original data on the sociodemographic profiles of these users, on their migration trajectory, their life conditions, and on the evolution of their drug use practices since arriving in Paris. METHODS: Data were collected as part of the ANRS-Coquelicot Survey, an HIV and HCV seroprevalence study among French-speaking people who use drugs. A sub-sample of Russian-speaking drug users who had relocated from Eastern Europe to live in Paris completed a quantitative questionnaire (N = 150) and a qualitative semi-structured interview (N = 20). The survey aimed to describe participants' backgrounds, and a thematic analysis of interviews was conducted to explore participants' migration histories, their life conditions in Paris, and their drug use practices before and after arriving in France. RESULTS: This study highlights the great vulnerability of the participating population, often following a loss of social status after migrating to France. Another important finding is that participants had better access to harm reduction tools and reduced their risk of exposure to HIV and HCV infections linked to needle sharing. Although 60% said they had already shared a syringe in their lifetime (49.9% of them in their home country), the proportions shrank to 13.9% after they arrived in France and to 9.3% in the month before the study, a proportion that is lower than among French-speaking people who use drugs. CONCLUSIONS: Our main findings on the profiles and behaviors of the study population lead us to make two recommendations: to offer stronger global care to these users in Paris and to reform drug policy in their home countries by integrating it into a public health approach.

RESUMO

BACKGROUND: Over the last 20 years, Hepatitis C virus (HCV) infection prevalence has dramatically increased among HIV-infected men who have sex with men (MSM) in many countries worldwide. It is suspected that this increase is primarily driven by sexual behaviours linked to blood exposure. Monitoring these behaviours is crucial to understand the drivers of the epidemic. This study assessed the prevalence of chronic HCV infection among MSM attending gay venues and associated chronic HCV risk factors. HCV screening and associated factors were described. METHODS: The cross-sectional survey PREVAGAY, based on time-location sampling, was conducted in 2015 among MSM attending gay venues in 5 French metropolitan cities. A self-administered questionnaire was completed and capillary whole blood on dried blood spots (DBS) collected. Possible factors associated with chronic HCV prevalence and with HCV screening in the previous year were investigated using Poisson regression. RESULTS: Chronic HCV infection prevalence from DBS analysis was 0.7% [IC95%: 0.3-1.5] in the study's 2645 participants and was 3.0% [1.5-5.8] in HIV-positive MSM. It was significantly higher in those who reported the following: (lifetime) slamming (with or without the sharing of injection equipment); (during the previous year) fisting and chemsex, unprotected anal intercourse with casual partners, using gay websites and/or of mobile-based GPS applications, and having more than 10 sexual partners. Only 41.3% [38.2-44.5] of the participants reported HCV screening during the previous year. Screening was significantly more frequent in MSM under 30 years of age, those who were HIV-positive, those vaccinated against hepatitis B and meningococcus C, and those who reported the following (during the previous year): more than 10 sexual partners, at least one sexually transmitted infection and fisting. CONCLUSION: Chronic HCV infection prevalence in MSM attending gay venues was significantly higher in HIV-positive MSM and in those with risky sexual behaviours. Reflecting current screening recommendations for specific populations, previous HCV screening was more frequent in HIV-positive individuals and those with risky sexual behaviours. Nevertheless, HCV screening coverage needs to be improved in these populations. Comprehensive medical management, which combines screening and linkage to care with prevention strategies, is essential to control HCV among MSM.

RESUMO

BACKGROUND & AIMS: Prevention of hepatitis C virus (HCV) transmission among people who inject drugs (PWID) is critical for eliminating HCV in Europe. We estimated the impact of current and scaled-up HCV treatment with and without scaling up opioid substitution therapy (OST) and needle and syringe programmes (NSPs) across Europe over the next 10 years. METHODS: We collected data on PWID HCV treatment rates, PWID prevalence, HCV prevalence, OST, and NSP coverage from 11 European settings. We parameterised an HCV transmission model to setting-specific data that project chronic HCV prevalence and incidence among PWID. RESULTS: At baseline, chronic HCV prevalence varied from <25% (Slovenia/Czech Republic) to >55% (Finland/Sweden), and <2% (Amsterdam/Hamburg/Norway/Denmark/Sweden) to 5% (Slovenia/Czech Republic) of chronically infected PWID were treated annually. The current treatment rates using new direct-acting antivirals (DAAs) may achieve observable reductions in chronic prevalence (38-63%) in 10 years in Czech Republic, Slovenia, and Amsterdam. Doubling the HCV treatment rates will reduce prevalence in other sites (12-24%; Belgium/Denmark/Hamburg/Norway/Scotland), but is unlikely to reduce prevalence in Sweden and Finland. Scaling-up OST and NSP to 80% coverage with current treatment rates using DAAs could achieve observable reductions in HCV prevalence (18-79%) in all sites. Using DAAs, Slovenia and Amsterdam are projected to reduce incidence to 2 per 100 person years or less in 10 years. Moderate to substantial increases in the current treatment rates are required to achieve the same impact elsewhere, from 1.4 to 3 times (Czech Republic and France), 5-17 times (France, Scotland, Hamburg, Norway, Denmark, Belgium, and Sweden), to 200 times (Finland). Scaling-up OST and NSP coverage to 80% in all sites reduces treatment scale-up needed by 20-80%. CONCLUSIONS: The scale-up of HCV treatment and other interventions is needed in most settings to minimise HCV transmission among PWID in Europe. LAY SUMMARY: Measuring the amount of HCV in the population of PWID is uncertain. To reduce HCV infection to minimal levels in Europe will require scale-up of both HCV treatment and other interventions that reduce injecting risk (especially OST and provision of sterile injecting equipment).

RESUMO

UNLABELLED: Hepatitis C virus (HCV) seroprevalence remains high in people who inject drug (PWID) populations, often above 60%. Highly effective direct-acting antiviral (DAA) regimens (90% efficacy) are becoming available for HCV treatment. This therapeutic revolution raises the possibility of eliminating HCV from this population. However, for this, an effective cascade of care is required. In the context of the available DAA therapies, we used a dynamic individual-based model including a model of the PWID social network to simulate the impact of improved testing, linkage to care, and adherence to treatment, and of modified treatment recommendation on the transmission and on the morbidity of HCV in PWID in France. Under the current incidence and cascade of care, with treatment initiated at fibrosis stage ≥F2, HCV prevalence decreased from 42.8% to 24.9% (95% confidence interval: 24.8-24.9) after 10 years. Changing treatment initiation criteria to treat from F0 was the only intervention leading to a substantial additional decrease in prevalence, which fell to 11.6% (95% CI: 11.6-11.7) at 10 years. Combining this change with improved testing, linkage to care, and adherence to treatment decreased HCV prevalence to 7.0% (95% CI: 7.0-7.1) at 10 years and avoided 15% (95% CI: 14-17) and 29% (95% CI: 28-30) of cirrhosis complications over 10 and 40 years, respectively. CONCLUSIONS: Major decreases in prevalent HCV infections occur only when treatment is initiated at early stages of fibrosis, suggesting that systematic treatment in PWID, where incidence remains high, would be beneficial. However, elimination within the 10 next years will be difficult to achieve using treatment alone, even with a highly improved cascade of care.

RESUMO

BACKGROUND: In France, information collected during postdonation interviews showed that a majority of human immunodeficiency virus (HIV)-infected donors were not eligible to donate as per donor selection criteria. In the interest of blood safety, this study aimed to explore the mechanisms of noncompliance with blood donor selection criteria, notably the permanent deferral of men who have sex with men (MSM). STUDY DESIGN AND METHODS: Semistructured individual interviews were conducted with 32 blood donors found positive for HIV between mid-2011 and 2014. Topics such as the experience and motivations for donating blood, understanding of selection criteria, sexual risk management, and opinions on donor selection were discussed. Transcripts were analyzed inductively. RESULTS: More than 50% of study participants were noncompliant with donor selection criteria. Reasons for nondisclosure of risk factors in the predonation questionnaire or the predonation interview included stigma, test-seeking motivations, symbolic attachment to blood donation, and context of donation. Compliance to donor criteria was seen as secondary by donors who reaped personal benefits from the symbolism of their donation. Donors lacked self-reflexivity in their assessment of risky sexual behavior. The "window period" and the underlying epidemiologic arguments for donor selection criteria were poorly understood. Nearly all participants disapproved of the permanent ban on blood donations from MSM. CONCLUSION: This study demonstrated the need for more communication on the epidemiologic basis for donor selection criteria and on the window period to facilitate donor compliance. These findings have already advanced improvements to predonation documents, in a larger context of 2016 donor selection criteria revision.
