Supervised injection facility use and all-cause mortality among people who inject drugs in Vancouver, Canada: A cohort study.

BACKGROUND: People who inject drugs (PWID) experience elevated rates of premature mortality. Although previous studies have demonstrated the role of supervised injection facilities (SIFs) in reducing various harms associated with injection drug use, including accidental overdose death, the possible impact of SIF use on all-cause mortality is unknown. Therefore, we examined the relationship between frequent SIF use and all-cause mortality among PWID in Vancouver, Canada. METHODS AND FINDINGS: Data were derived from 2 prospective cohort studies of PWID in Vancouver, Canada, between December 2006 and June 2017. Every 6 months, participants completed questionnaires that elicited information regarding sociodemographic characteristics, substance use patterns, social-structural exposures, and use of health services including SIFs. These data were confidentially linked to the provincial vital statistics database to ascertain mortality rates and causes of death. We used multivariable extended Cox regression analyses to estimate the independent association between frequent (i.e., at least weekly) SIF use and all-cause mortality. Of 811 participants, 278 (34.3%) were women, and the median age was 39 years (IQR 33-46) at baseline. In total, 432 (53.3%) participants reported frequent SIF use at baseline, and 379 (46.7%) did not. At baseline, frequent SIF users were on average younger than nonfrequent users, and a higher proportion of frequent SIF users than nonfrequent users were unstably housed, resided in the Downtown Eastside neighbourhood, injected in public, had a recent non-fatal overdose, used prescription opioids at least daily, injected heroin at least daily, injected cocaine at least daily, and injected crystal methamphetamine at least daily. A lower proportion of frequent SIF users than nonfrequent users were HIV positive and enrolled in addiction treatment at baseline. The median duration of follow-up among study participants was 72 months (IQR 24-123). In total, 112 participants (13.8%) died during the study period, yielding a crude mortality rate of 22.7 (95% CI 18.7-27.4) deaths per 1,000 person-years. The median years of potential life lost per death was 34 (IQR 27-42) years. In a time-updated multivariable model, frequent SIF use was inversely associated with risk of all-cause mortality after adjusting for potential confounders, including age, sex, HIV seropositivity, unstable housing, at least daily cocaine injection, public injection, incarceration, enrolment in addiction treatment, and calendar year of interview (adjusted hazard ratio 0.46, 95% CI 0.26-0.80, p = 0.006). The main study limitations are the limited generalizability of findings due to non-random sampling, the potential for reporting biases due to reliance on some self-reported information, and the possibility that residual confounding influenced findings. CONCLUSIONS: We observed a high burden of premature mortality among a community-recruited cohort of PWID. Frequent SIF use was associated with a lower risk of death, independent of relevant confounders. These findings support efforts to enhance access to SIFs as a strategy to reduce mortality among PWID. Further analyses of individual-level data are needed to determine estimates of, and potential causal pathways underlying, associations between SIF use and specific causes of death.

Developing Safe Syringe Exchange Programs: Role of the North Carolina Division of Public Health.

Syringe exchange programs became legal in North Carolina on July 11, 2016. A combination of forces led to this progressive public health measure, including advocacy of the State Health Official, in a state characterized by a conservative political climate. Data collected by the division of public health were a key contributor to the initiative. Nearly 5 North Carolinians died each day from unintentional medication or drug overdose. High rates of coinfection including hepatitis B and C, human immunodeficiency virus, and endocarditis were shown to have substantial economic consequences. The North Carolina Harm Reduction Coalition and use of Moral Foundations Theory in crafting messages were important in influencing legislation. North Carolina now has 30 active syringe exchange programs serving 40 counties. Individuals using intravenous drugs who take advantage of these syringe exchange programs are provided with clean needles to not only help prevent the spread of illness but also learn more about safe health practices.

Supervised injection facilities in Canada: past, present, and future.

Canada has long contended with harms arising from injection drug use. In response to epidemics of HIV infection and overdose in Vancouver in the mid-1990s, a range of actors advocated for the creation of supervised injection facilities (SIFs), and after several unsanctioned SIFs operated briefly and closed, Canada's first sanctioned SIF opened in 2003. However, while a large body of evidence highlights the successes of this SIF in reducing the health and social harms associated with injection drug use, extraordinary efforts were needed to preserve it, and continued activism by local people who inject drugs (PWID) and healthcare providers was needed to promote further innovation and address gaps in SIF service delivery. A growing acceptance of SIFs and increasing concern about overdose have since prompted a rapid escalation in efforts to establish SIFs in cities across Canada. While much progress has been made in that regard, there is a pressing need to create a more enabling environment for SIFs through amendment of federal legislation. Further innovation in SIF programming should also be encouraged through the creation of SIFs that accommodate assisted injecting, the inhalation of drugs. As well, peer-run, mobile, and hospital-based SIFs also constitute next steps needed to optimize the impact of this form of harm reduction intervention.

Trend Analyses of Users of a Syringe Exchange Program in Philadelphia, Pennsylvania: 1999-2014.

This study examines trends of injection drug users' (IDUs) use of a Philadelphia, Pennsylvania, syringe exchange program (SEP) from 1999 to 2014, including changes in demographics, drug use, substance abuse treatment, geographic indicators, and SEP use. Prevention Point Philadelphia's SEP registration data were analyzed using linear regression, Pearson's Chi square, and t-tests. Over time new SEP registrants have become younger, more racially diverse, and geographically more concentrated in specific areas of the city, corresponding to urban demographic shifts. The number of new registrants per year has decreased, however syringes exchanged have increased. Gentrification, cultural norms, and changes in risk perception are believed to have contributed to the changes in SEP registration. Demographic changes indicate outreach strategies for IDUs may need adjusting to address unique barriers for younger, more racially diverse users. Implications for SEPs are discussed, including policy and continued ability to address current public health threats.

Why do the clients of Georgian needle exchange programmes inject buprenorphine?

AIM: The aim of the study was to understand the prevalence and patterns of the non-medical injecting use of buprenorphine among drug injectors in Georgia. METHOD: A self-administered questionnaire was distributed among injecting drug users enrolled in Georgian needle exchange programmes. The questions covered topics related to drug use career, patterns (frequency, history, dosage) and reasons for the use of buprenorphine. RESULTS: Pharmaceutical buprenorphine in the form of Subutex was the most commonly injected drug in terms of lifetime (95.5%) and last-month (75%) prevalence of use. 48% of those study participants who had injected Subutex at some point reported having used it to cope with withdrawal or to give up other opioids. 90.5% of Subutex injectors used 1-2 mg as a single dose, and the mean frequency of its injection was 6 times per month. 75% of Subutex injectors had used 3 or more types of illegal drugs during the last 30 days. CONCLUSION: While widely misused by Georgian drug injectors, Subutex is neither the principal nor the favourite drug, and it is rather used as self-treatment. The authors consider the introduction of buprenorphine maintenance treatment to be a promising effective measure to decrease its non-medical and illegal use.

Understanding the increase in opioid overdoses in New Hampshire: A rapid epidemiologic assessment.

BACKGROUND: New Hampshire (NH) has had among the highest rates of fentanyl-related overdose deaths per capita in the United States for several years in a row-more than three times the national average in 2016. This mixed-methods study investigated drug-using practices and perspectives of NH residents who use opioids to inform policy in tackling the overdose crisis. METHODS: Seventy-six participants from six NH counties completed demographic surveys and semi-structured interviews focused on drug-using practices and perspectives, including use precursors, fentanyl-seeking behaviors, and experiences with overdose. Rigorous qualitative methods were used to analyze interview data including transcription, coding and content analysis. Descriptive statistics were calculated on quantitative survey data. RESULTS: Eighty-four percent of interviewees had knowingly used fentanyl in their lifetime, 70 % reported overdosing at least once, and 42 % had sought a batch of drugs known to have caused an overdose. The majority stated most heroin available in NH was laced with fentanyl and acknowledged that variability across batches increased overdose risk. Participants reported high availability of fentanyl and limited access to prevention, treatment, and harm reduction programs. There was widespread support for expanding education campaigns for youth, increasing treatment availability, and implementing needle exchange programs. CONCLUSIONS: A confluence of factors contribute to the NH opioid overdose crisis. Despite consensus that fentanyl is the primary cause of overdoses, individuals continue to use it and affirm limited availability of resources to address the problem. Policies targeting innovative prevention, harm reduction, and treatment efforts are needed to more effectively address the crisis.

[The efficacy of needle exchange programs in the prevention of HIV and hepatitis infection among injecting drug users]. / A tucsereprogramok hatékonysága az injektáló droghasználók közötti HIV- és hepatitisz fertozés megelozésében.

BACKGROUND: HIV infection has become one of the major public health problems of our time. An estimated 33.2 million people lived worldwide with HIV in 2007. Injecting drug users are the most at risk group of HIV infection in many regions of the world. Injecting drug use became the primary route of infection in Western- and Central Europe, also in North America and Australia, and dominated from the beginning of the epidemic in Eastern Europe and Central Asia. GOALS: Identifying drug users as risk groups has evoked a series of intervention possibilities, of which the authors introduce and assess the effectiveness of needle and syringe exchange programs. METHODS: We evaluated a literature search by the use of MEDLINE, PsycINFO and Web of Science databases. RESULTS: After reviewing the scientific literature the authors conclude that needle and syringe exchange programs are an effective way of reducing risky behaviors related to injecting drug use, hence they are effective in reducing the spread of HIV among injecting drug users and the population. The authors introduce the literature related to the effectiveness of various kinds of programs for distributing sterile injecting equipment. CONCLUSION: Besides various kinds of prevention programs and harm reduction measures, when adopted to the given populations needs and socio-cultural circumstances, the providing of needle and syringe programs are an indispensable condition of successfully preventing the spread of HIV.

Evaluation of contingency management as a strategy to improve HCV linkage to care and treatment in persons attending needle and syringe programs: A pilot study.

BACKGROUND: A greater proportion of HCV-infected people who inject drugs (PWID) need to be linked to care for HCV antiviral treatment. This study sets out to evaluate the efficacy of contingency management (CM) for improving HCV linkage to care, treatment initiation, adherence, and cure for PWID recruited from a needle and syringe program. METHODS: Between March 2015 and April 2016, 20 participants were enrolled into the CM arm, and then subsequently enrolled 20 participants in the enhanced standard of care (eSOC) arm. Participants in the eSOC arm received an expedited appointment and a round-trip transit card. Participants enrolled in the CM arm received eSOC plus $25 for up to ten HCV clinical visits and $10 for each returned weekly medication blister pack. Adherence was measured via electronic blister packs. RESULTS: Overall the median age was 47 years; most were men (67%) and Hispanic (69%). There were no significant differences in demographic characteristics between participants in the study arms. In the CM arm 74% were linked to HCV care, compared to 30% in the eSOC arm (p = 0.01). In the CM arm, 75% (9/12) of treatment eligible participants initiated treatment, compared to 100%(4/4) in the eSOC arm (p = 0.53). All patients (9/9) achieved cure in the CM arm, as compared to 75% (3/4) of patients in the eSOC arm. There were no differences in adherence between study arms. CONCLUSIONS: In this pilot study, contingency management led to higher rates of HCV linkage to care for PWID, as compared to standard of care. CM should be considered as a possible intervention to improve the HCV treatment cascade for PWID.

Take-home naloxone possession among people who inject drugs in rural West Virginia.

BACKGROUND: Take-home naloxone (THN) possession among people who inject drugs (PWID) in rural communities is understudied. Better understanding the nature of THN possession among rural PWID could inform the implementation of overdose prevention initiatives. The purpose of this research is to determine factors associated with rural PWID having recently received THN. METHODS: Data from a PWID population estimation study implemented in Cabell County, West Virginia were used for this research. Multivariable Poisson regression with a robust variance estimator was used to evaluate the independent effects of several measures (e.g., sociodemographics, structural vulnerabilities, substance use) on PWID having received THN in the past 6 months. RESULTS: Forty-eight percent of our sample (n = 371) of PWID reported having received THN in the past 6 months. Factors associated with having received THN were: age (adjusted Prevalence Ratio [aPR] = 1.02; 95% Confidence Interval [CI]: 1.01-1.03), having recently accessed sterile syringes at a needle exchange program (aPR = 1.82; 95% CI: 1.35-2.46), believing that doctors judge people who use drugs (aPR = 1.50; 95% CI: 1.07-2.12), and having witnessed at least one non-fatal overdose in the past 6 months (aPR = 1.44; 95% CI: 1.06-1.94). Greater numbers of overdose events in the past 6 months were also associated with having received THN. CONCLUSIONS: Among rural PWID in West Virginia, slightly less than half received THN in the past 6 months. Rural communities need overdose prevention interventions that are responsive to the unique needs of rural PWID, decrease stigma, and ensure PWID have access to harm reduction services and drug treatment programs.

Changing risk and presentation of overdose associated with consumption of street drugs at a supervised injection site in Vancouver, Canada.

BACKGROUND: British Columbia is experiencing a public health emergency due to overdoses resulting from consumption of street drugs contaminated with fentanyl. While the risk of overdoses appears to be increasing, the overdose rate and severity of overdose presentations have yet to be quantified. METHODS: Insite is a supervised injection site in Vancouver. Data from Insite's client database from January 2010 to June 2017 were used to calculate overdose rates as well as the proportion of overdoses involving rigidity and naloxone administration over time in order to estimate changes in the risk and severity of overdose resulting from changes in the local drug supply. RESULTS: The overdose rate increased significantly for all drug categories. Heroin used alone or with other drugs continues to be associated with the highest overdose rate. The overdose rate associated with heroin increased from 2.7/1000 visits to 13/1000 visits over the study period, meaning that clients were 4.8 times more likely to overdose in the most recent period as in the baseline period. The proportion of overdose events involving rigidity, a known complication of intravenous fentanyl use, increased significantly from 10.4% to 18.9%. The proportion of overdoses requiring naloxone administration increased significantly from 48.4% to 57.1% and is now similar across all drug categories. CONCLUSIONS: The risk and severity of overdoses at Insite have increased since the emergence of illicit fentanyl. This information derived from supervised injection site data can be used to inform local harm reduction efforts and the response to the overdose emergency.

Changes in supervised drug-injecting practices following a community-based educational intervention: A longitudinal analysis.

BACKGROUND: People who inject drugs face several health issues because of unsafe injecting practices. We aimed to evaluate changes in supervised drug-injecting practices following the implementation of a face-to-face educational intervention. METHODS: The national study ANRS-AERLI was conducted in 17 harm reduction (HR) facilities in France between 2011 and 2013. Eight offered the intervention and nine did not. We conducted a pre-post analysis focusing on injecting practices data, collected in the 8 HR facilities providing the intervention. The intervention consisted of providing face-to-face educational sessions including direct observation of injecting practices, counseling about safer injecting, and shared discussion. Injecting practices were collected following a checklist and classified as safe or unsafe. To assess changes in injecting practices, practices were compared before (at baseline) and after at least one educational session. FINDINGS: Mixed logistic models showed that the 78 participants included were more likely to improve in the following drug-use steps: setting up a clean preparation area (Adjusted Odds Ratio (AOR) = 3.4, 95% Confidence Interval (95% CI) = 1.6-7.6), hand washing (AOR = 7.2, 95% CI = 3.1-16.4), skin cleaning (AOR = 5.6, 95% CI = 2.5-12.1), choice of safe injection site (AOR = 6.5, 95% CI = 1.5-28.8) and post-injection bleeding management (AOR = 12.8, 95% CI = 5.5-29.9). Furthermore, participants were less likely to lick their needles before injecting (AOR = 8.1, 95% CI = 1.5-43.4) and to perform booting/flushing (AOR = 2.5, 95% CI = 1.2-5.3). CONCLUSIONS: The AERLI intervention seems to be effective in increasing safe drug-injecting practices.

Are there differences in individual-level needle and syringe coverage across Australian jurisdictions related to program policy? A preliminary analysis.

INTRODUCTION AND AIMS: Services provided by needle and syringe programs (NSP) within Australia are easily accessible by international standards. However, important variation in NSP policy remains across Australian jurisdictions. The potential impacts of these variations on program operation for clients have not been systematically analysed in Australia. In this paper we conduct a preliminary examination to compare individual-level syringe coverage between and within Australian capital cities. DESIGN AND METHODS: Participants were 2498 people who inject drugs (PWID) recruited from all Australian capital cities as part of the annual Illicit Drug Reporting System PWID survey over the period 2014-2016. Insufficient coverage was defined when <100% of a participant's injecting episodes were 'covered' by sterile needles and syringes. We report the percentage of insufficient coverage for each capital city for each year, and present descriptive statistics for coverage parameters, and an alternative measure for insufficient coverage, as Supporting Information. RESULTS: Differences in behaviours that have the potential to impact syringe coverage were highly variable over time and place leading to variations in levels of insufficient coverage between and within all cities. Overall, insufficient coverage was most evident in larger cities where insufficient coverage varied between 19% and 23% (Sydney) over time, compared to smaller cities with variation from 9% to 12% (Adelaide). DISCUSSION AND CONCLUSIONS: We found no consistent pattern of differences in individual-level needle and syringe coverage between and within Australian capital cities. Further work is needed to fully evaluate whether policy variation between Australian jurisdictions impacts on NSP coverage.

More free syringes, fewer drug injectors in the case of Spain.

International policy on the prevention of HIV and other health problems among drug users should be guided by scientific evidence. However, it has frequently been argued that Needle Exchange Programs (NEPs) have negative effects such as facilitation of injection of illicit drugs, without providing evidence to support this hypothesis. Since the early 1980s Spain has experienced a severe HIV epidemic among drug injectors. A delayed but comprehensive implementation of harm reduction programs has taken place since the early 1990s. This paper assesses trends between 1991 and 2004, both in the number of sterile syringes exchanged or delivered by NEPs or other programs to improve injectors' access to sterile injection material, and in the number of injectors admitted to first treatment for heroin or cocaine dependence, as a proxy for trends in the number of new drug injectors in Spain. The results show increased access to sterile syringes and a sharp decrease in the number of new drug injectors, suggesting that NEPs have not promoted drug injection. A positive overall transition from injecting to smoking was also observed in the most frequent route of heroin or cocaine administration.

Longitudinal analysis of change in individual-level needle and syringe coverage amongst a cohort of people who inject drugs in Melbourne, Australia.

BACKGROUND: Needle and syringe program (NSP) coverage is often calculated at the individual level. This method relates sterile needle and syringe acquisition to injecting frequency, resulting in a percentage of injecting episodes that utilise a sterile syringe. Most previous research using this method was restricted by their cross-sectional design, calling for longitudinal exploration of coverage. METHODS: We used the data of 518 participants from an ongoing cohort of people who inject drugs in Melbourne, Australia. We calculated individual-level syringe coverage for the two weeks prior to each interview, then dichotomised the outcome as either "sufficient" (≥100% of injecting episodes covered by at least one reported sterile syringe) or "insufficient" (<100%). Time-variant predictors of change in recent coverage (from sufficient to insufficient coverage) were estimated longitudinally using logistic regression with fixed effects for each participant. RESULTS: Transitioning to methamphetamine injection (AOR:2.16, p=0.004) and a newly positive HCV RNA test result (AOR:4.93, p=0.001) were both associated with increased odds of change to insufficient coverage, whilst change to utilising NSPs as the primary source of syringe acquisition (AOR: 0.41, p=0.003) and opioid substitution therapy (OST) enrolment (AOR:0.51, p=0.013) were protective against a change to insufficient coverage. CONCLUSIONS: We statistically tested the transitions between time-variant exposure sub-groups and transitions in individual-level syringe coverage. Our results give important insights into means of improving coverage at the individual level, suggesting that methamphetamine injectors should be targeted, whilst both OST prescription and NSP should be expanded.

Death from liver disease in a cohort of injecting opioid users in a Swedish city in relation to registration for opioid substitution therapy.

INTRODUCTION AND AIMS: Injecting opioid users are at elevated risk of death. Although liver disease (especially hepatitis C) is common, its impact on mortality is low in active injectors. Because opioid substitution therapy (OST) reduces the risk of death from directly drug related causes, we hypothesised that the proportion of liver-related deaths would increase in subjects receiving OST. We investigated liver-related mortality in a cohort of injecting opioid users attending a needle exchange program (NEP) in a Swedish city in relation to OST exposure. DESIGN AND METHODS: Participants enrolled in the NEP between 1987 and 2011 with available national identity numbers, and registered use of opioids, were included. Linkage based on national identity numbers was performed with national registers for death, emigration and prescription of OST. Participants were categorised as non-OST recipients until the registered date of first OST prescription, and hence as OST recipients. Hazard ratios were calculated by Cox regression for overall and liver-related mortality in relation to OST, with OST as a time-dependent variable. RESULTS: Among 4494 NEP participants, 1488 opioid users were identified; 711/1488 had been prescribed OST. During a follow-up period of 15 546 person-years 368 deaths occurred. Sixteen deaths were caused by liver disease; 10 of these occurred in OST recipients. The risk of liver-related death was significantly increased in OST receiving participants (hazard ratio 3.08, 95% confidence interval [1.09, 8.68], P = 0.03). CONCLUSIONS: Liver related mortality among opioid users was significantly elevated in OST recipients, showing the long-term importance of chronic liver disease in this population.

Global, regional, and country-level coverage of interventions to prevent and manage HIV and hepatitis C among people who inject drugs: a systematic review.

BACKGROUND: People who inject drugs (PWID) are a key population affected by the global HIV and hepatitis C virus (HCV) epidemics. HIV and HCV prevention interventions for PWID include needle and syringe programmes (NSP), opioid substitution therapy (OST), HIV counselling and testing, HIV antiretroviral therapy (ART), and condom distribution programmes. We aimed to produce country-level, regional, and global estimates of coverage of NSP, OST, HIV testing, ART, and condom programmes for PWID. METHODS: We completed searches of peer-reviewed (MEDLINE, Embase, and PsycINFO), internet, and grey literature databases, and disseminated data requests via social media and targeted emails to international experts. Programme and survey data on each of the named interventions were collected. Programme data were used to derive country-level estimates of the coverage of interventions in accordance with indicators defined by WHO, UNAIDS, and the UN Office on Drugs and Crime. Regional and global estimates of NSP, OST, and HIV testing coverage were also calculated. The protocol was registered on PROSPERO, number CRD42017056558. FINDINGS: In 2017, of 179 countries with evidence of injecting drug use, some level of NSP services were available in 93 countries, and there were 86 countries with evidence of OST implementation. Data to estimate NSP coverage were available for 57 countries, and for 60 countries to estimate OST coverage. Coverage varied widely between countries, but was most often low according to WHO indicators (<100 needle-syringes distributed per PWID per year; <20 OST recipients per PWID per year). Data on HIV testing were sparser than for NSP and OST, and very few data were available to estimate ART access among PWID living with HIV. Globally, we estimate that there are 33 (uncertainty interval [UI] 21-50) needle-syringes distributed via NSP per PWID annually, and 16 (10-24) OST recipients per 100 PWID. Less than 1% of PWID live in countries with high coverage of both NSP and OST (>200 needle-syringes distributed per PWID and >40 OST recipients per 100 PWID). INTERPRETATION: Coverage of HIV and HCV prevention interventions for PWID remains poor and is likely to be insufficient to effectively prevent HIV and HCV transmission. Scaling up of interventions for PWID remains a crucial priority for halting the HIV and HCV epidemics.

Spain is the Western European country with the highest prevalenceof Human Immunodeficiency Virus among people who inject drugs.The Hepatitis-C Virus affects over fifty per cent of this population. Atthe same time, the World Health Organization considers that the average coverage of injection material for drug user per year is low. Harmreduction programs and services have been deployed for over thirtyyears, and these could now incorporate the advantages of eHealth andmHealth to improve harm reduction. The aim of this qualitative anddescriptive study is to analyze how people who inject drugs perceive anapplication for mobile devices. Fifty-one such drug users participatedactively in five focus groups. The main results of the thematic content analysis indicated that the application was welcomed as easy anduseful. Participants reported that the application contributed to improving access to injection material, reducing the stigma of drug-dependence and optimizing the organization of the ritual of injection.Excessive preventive information and problems downloading the webapp were identified as aspects for improvement. In conclusion, theapplication was seen as a useful eHealth tool that complements thenormal intervention of needle exchange programs. (AU)

Veni, vidi, vici: The appearance and dominance of new psychoactive substances among new participants at the largest needle exchange program in Hungary between 2006 and 2014.

BACKGROUND: There has been an almost exponential growth in the number of new psychoactive substances (NPS) on the drug markets in Europe during the past decade. While most users of NPS use them by routes other than injecting, percutaneous use of NPS is associated with very frequent injecting episodes and paraphernalia sharing. METHODS: We assessed to what extent new clients between 2006 and 2014 (N=3680) at Blue Point, Hungary's largest needle exchange program, exhibited a shift during these years in the drugs they primarily injected. RESULTS: Until 2010, 99% of clients injected either heroin or amphetamines. After 2010, however, there was a "replacement chain" of new substances, with one appearing and disappearing after the other: between 2010 and 2014, NPS under five names appeared and gained dominant prevalence (from 0% to 80%), and gradually replaced first the two "traditional" drugs amphetamine and heroin (which diminished to 17% together in 2014) and later each other. We also saw an increase in the proportion of female and older clients. CONCLUSIONS: While our findings are restricted to injected NPS, they suggest that NPS affect the vast majority of the population of people who inject drugs not only in terms of drug use patterns, but maybe also in terms of demographics. Given that over 80% of people who inject drugs use NPS and injecting NPS is associated with increased injecting risks, harm reduction services should be made more available to avoid an epidemic of blood-borne infections.

Drug analysis of residual content of used syringes: a new approach for improving knowledge of injected drugs and drug user practices.

BACKGROUND: Since their inception, harm reduction services, including needle exchange programs, have aimed to improve and update knowledge about illicit drug consumption and injection practices in order to assess and regularly revise the effectiveness of preventive strategies. METHODS: In this paper we describe the development of a scientific approach to obtaining this type of information through analysis of the residual content of used syringes. This was done using a validated liquid chromatography method with mass spectrometry detection to identify different molecules. Used syringes were collected from automatic injection kit dispensers at 17 sites in Paris and the surrounding suburbs each month for one year. RESULTS: In total, 3489 syringes were collected. No compounds were detected in 245 syringes. Heroin was the most commonly observed compound (42%), followed by cocaine (41%), buprenorphine (29%) and 4-methylethylcathinone (23%). These analyses also showed the increased appearance of 4-methylethylcathinone between the summer and winter of 2012. CONCLUSIONS: Despite the bias involved in this approach, the method can provide rapid data on patterns of drug consumption for specific time periods and for well-defined locations. This kind of analysis enables the detection of new substances being injected and thus enables harm reduction services to revise and adapt prevention strategies.

Declining risk for HIV among injecting drug users in Kathmandu, Nepal: the impact of a harm-reduction programme.

OBJECTIVE: To measure changes in self-reported risk behaviour for HIV infections and HIV seroprevalence among injecting drug user (IDU) clients of an outreach harm-reduction programme in Kathmandu, Nepal. METHODS: The Lifesaving and Lifegiving Society (LALS) of Kathmandu began providing sterile injecting equipment and education to Nepalese IDU in 1991. A sample of these IDU were interviewed and tested for HIV each year from 1991 through 1994. RESULTS: Indicators of unsafe injecting fell, as knowledge of HIV rose more in 1994 for those who had been in touch with LALS for longer. Indicators of unsafe sex did not change. HIV seroprevalence remained low, 1.6% in 1991 and 0% in 1994. CONCLUSION: We conclude that programmes for the prevention of HIV spread among IDU are possible and effective in Asia, and are urgently needed.

PIP: To reduce the high rate of human immunodeficiency virus (HIV) infection among intravenous drug users in Nepal, the Lifesaving and Lifegiving Society of Kathmandu has been distributing sterile injecting equipment in exchange for contaminated materials since 1991. In addition, community health outreach workers affiliated with the program provide condoms and bleach, HIV counseling and education, and primary health care to about 750 of the estimated 1500-2000 intravenous drug users in the Kathmandu valley. Of the 48,386 client contacts in 1991-94, over half involved syringe exchange. During this period, 586 randomly selected clients were selected for interviews and serologic testing. The number of times drug users shared equipment declined from 14 times per week in the 1991 subsample to once a day or less in the 1993 and 1994 subsamples. Knowledge of HIV infection rose from 58% in 1991 to almost 100% in 1994, while the proportion of drug users considering themselves at risk of HIV increased from 25% to 47%. There were no significant changes in HIV seropositivity (1.6% in 1991) during the study period, and no new cases were recorded in 1993 or 1994. This finding confirms the effectiveness of needle/syringe exchange programs in controlling the spread of HIV infection among intravenous drug users.
