Injecting drug use and unstable housing: Scope for structural interventions in harm reduction

Financial Vulnerability and Its Association with HIV Transmission Risk Behaviors Among People Who Inject Drugs in Kyrgyzstan

The Family Resource Scale (FRS) is a three-factor financial vulnerability (FV) measure. FV may impact HIV transmission risks. Cross-sectional data from 279 people who inject drugs (PWID) in Kyrgyzstan surveyed April-October 2021 was used to validate the FRS and estimate associations between FV on past 6-month injection and sexual HIV risk outcomes. The three-factor FRS reflected housing, essential needs, and fiscal independence, and had good internal reliability and structural validity. Greater cumulative, housing, and essential needs FRS scores were associated with increased relative risk on public injection (adjusted risk ratio [aRR], 95% confidence interval [95% CI]: 1.03 [1.01, 1.04]; aRR [95% CI]: 1.06 [1.02, 1.09]; aRR [95% CI]: 1.06 [1.03, 1.08], respectively, all p < 0.001) and preparing injections with unsafe water sources (aRR [95% CI]: 1.04 [1.02, 1.07]; aRR [95% CI]: 1.09 [1.04, 1.15]; aRR [95% CI]: 1.08 [1.03, 1.14], respectively, all p < 0.001). Results suggest that PWID housing- and essential needs-related FV may exacerbate injection HIV transmission risks. Reducing PWIDs' FV may enhance the HIV response in Kyrgyzstan.

Victimization, safety, and overdose in homeless shelters: A systematic review and narrative synthesis

The objective of this prospectively registered systematic review was to identify the factors that contribute to sense of safety, victimization, and overdose risk in homeless shelters, as well as groups that are at greater risk of shelter-based victimization. Fifty-five articles were included in the review. Findings demonstrated that fears of violence and other forms of harm were prominent concerns for people experiencing homelessness when accessing shelters. Service users' perceptions of shelter dangerousness were shaped by the service model and environment, interpersonal relationships and interactions in shelter, availability of drugs, and previous living arrangements. 2SLGBTQ+ individuals were identified as being at heightened risk of victimization in shelters. No studies examined rates of shelter-based victimization or tested interventions to improve safety, with the exception of overdose risk. These knowledge gaps hinder the establishment of evidence-based practices for promoting safety and preventing violence in shelter settings.

Housing instability and violence among women who use drugs in Dar es Salaam, Tanzania

BACKGROUND

Women who use heroin and other drugs (WWUD) are a key population with elevated risk of physical and sexual violence perpetrated by intimate partners and non-partners. While housing instability has been shown to be associated with violence in high-income settings, this is an underexplored topic in sub-Saharan Africa. In this research, we aimed to assess the relationship between housing instability and various forms of violence within a sample of WWUD in Dar es Salaam.

METHODS

This analysis uses data from a parent study from 2018. A total of 200 WWUD were recruited through respondent-driven sampling methods and administered a survey. Two multivariable logistic regression models were built to assess the relationship between housing instability and physical violence (Model 1) and housing instability and sexual violence (Model 2) while controlling for a number of sociodemographic characteristics.

RESULTS

Approximately 35% of participants were classified as housing unstable. More than half of participants (62%) reported experiencing physical violence in the past 12 months, and more than a third (36%) reported sexual violence in the same time period. Housing instability was found to be independently associated with both physical and sexual violence victimization in the past year when adjusting for covariates (Model 1 adjusted odds ratio [AOR]: 2.40, 95% CI 1.22-4.46; Model 2 AOR: 1.93. 95% CI 1.02-3.67).

CONCLUSION

To our knowledge, this is the first study to document a significant association between housing instability and violence among WWUD communities in sub-Saharan Africa. This analysis adds to the growing body of literature on the relationship between stable housing and livelihood and health outcomes across differing populations. The cyclical nature of housing instability and violence may be disrupted through housing programming that provides safety, security, and stability for WWUD.

Rapid situational assessment of people who inject drugs (PWID) in Nairobi and coastal regions of Kenya: a respondent driven sampling survey

BACKGROUND

A Cross-sectional Rapid Situational Assessment of People Who Inject Drug (PWIDs) applying Respondent Driven sampling techniques (RDS) was used to recruit subjects/participants in a study aimed at assessing HIV prevalence and risk behaviors among injecting drug users in Nairobi and Coastal regions of Kenya. There is paucity of data and information on injecting drug use in sub-Saharan Africa and there is sufficient evidence of existence of the environment for development and growth of injecting drug use. Past studies on PWID and its association to HIV and AIDS that have been conducted in Kenya do not provide sufficient information to support effective planning and comprehensive national response to the HIV and AIDS epidemic.

METHODS

A cross-sectional study design was adopted in which a set of initial subjects referred to as 'seeds' were first identified from which an expanding chain of referrals were obtained, with subjects from each wave referring subjects of subsequent waves. The seeds were drawn randomly from the population and interviewed to pick the one with the largest network and other unique characteristics. A maximum of twelve seeds were recruited. The second stage involved conducting assessment visits to the sites to identify potential collaborators that included non-governmental organizations (NGOs), drug treatment centres, health facilities, community based organizations (CBO's) among others. Three NGOs located in the coast region and one in Nairobi region were identified to assist in identifying drug injection locations and potential participants. Key informant interviews (KIIs) and Focus Group Discussions (FGDs) were also conducted using interview guides.

RESULTS

A total of 646 individuals (344 in Nairobi and 302 at the coast) were recruited for the study between January and March 2010. Of these 590 (91%) were male and 56 (9%) were female. Findings showed that most PWIDs initiated injecting drug use between the ages of 20-29 years, with the youngest age of initiation being 11 years and oldest age being 53 years. Most commonly injected drug was heroin (98%), with a small (2%) percentage injecting cocaine. Other non-injecting methods such as smoking or combining these two drugs with other drugs such as cannabis or Rohypnol were also common. Most PWIDs used other substances (cigarettes, alcohol, and cannabis) before initiating injecting drug use. The adjusted national HIV prevalence of PWIDs was 18.3% (19.62% unadjusted) with PWIDs in Nairobi region registering 18.33% (20.58% unadjusted) compared PWIDs for Coastal region indicating 18.27% (18.59% - unadjusted). The gender based HIV prevalence showed that women were more at risk of acquiring HIV (44.51%-adjusted) compared to men (15.97%-adjusted). The age specific HIV prevalence showed that PWIDs who initiated injecting at 11-19 years (44.7% adjusted) were most at risk in Nairobi compared to those who initiated injecting at age 20-24 years (23.2% - adjusted) in the coastal region. While all PWIDs continue to be at risk in the two regions, those from the Western parts of Nairobi, Kenya were at a relatively higher risk given their increased propensity for sharing injecting equipment and solutions.

CONCLUSIONS

Compared to the national HIV prevalence of (4.9%), the results show that People Who Inject Drugs (PWIDs) are at particularly high risk of infection in Kenya and there is urgent need for intervention (KenPHIA, 2018). This study also showed clear evidence that 70% of PWIDs are primary school educated, engage in high risk injecting and sexual behaviors comprising sharing of injecting equipment, unprotected heterosexual and homosexual sex. Given that initiation of injecting drug use begins early and peaks after formal school years (20-29 years), prevention programmes should be targeted at primary and secondary school students, college and out of school youth. Further, to protect People who inject drugs (PWIDs) from HIV infection, the country should introduce free Needle Syringe Programs (NSP) with provision of condoms and Methadone Assisted Therapy (MAT) as a substitute for drug use.

Deconstructing the 'cheque effect': short-term changes in injection drug use after receiving income assistance and associated factors

BACKGROUND AND AIMS

Disbursement of income assistance has been temporally associated with intensified drug use and related harms (coined the 'cheque effect'). However, relationships to injection drug use (IDU) remain understudied. We examined short-term 'cheque effects' and associated factors among people who inject drugs (PWID).

DESIGN

Cross-sectional analysis nested within a cohort study.

SETTING

Montreal, Quebec, Canada.

PARTICIPANTS

PWID receiving income assistance, with no employment income. A total of 613 PWID (median age 41, 83% male) contributed 3269 observations from 2011 to 2017.

MEASUREMENTS AND METHODS

At each cohort visit, an interviewer-administered questionnaire captured retrospective reports of injection-related behaviour during the 2-day periods (i) before and (ii) including/after receiving last month's income assistance payment (number of injections; drugs injected; any receptive syringe-sharing). The relative likelihood (odds) and magnitude (rate) of an increase in injection frequency ('cheque effect') were estimated in relation to social and behavioural factors using logistic and negative binomial regression in a covariate-adjusted two-part model.

FINDINGS

Prevalence of IDU and syringe-sharing were, respectively, 1.80 and 2.50 times higher in the days following versus preceding cheque receipt (P < 0.001). Among people with past-month IDU, most observations showed increased injection frequency (52%) or no change in injection frequency (44%). The likelihood of a 'cheque effect' was positively associated with cocaine injection [versus injection of other substances, odds ratio (OR) = 2.639, 95% confidence interval (CI) = 2.04-3.41], unstable housing (OR = 1.272, 95% CI = 1.03-1.57) and receiving opioid agonist therapy (OR =1.597, 95% CI = 1.27-2.00) during the same month. Magnitude of the 'cheque effect' was positively associated with cocaine injection [rate ratio (RR) = 1.795, 95% CI = 1.43-2.16], unstable housing (RR = 1.198, 95% CI = 1.02-1.38) and frequent injection (RR = 2.938, 95% CI = 2.43-3.44), but inversely associated with opioid agonist therapy (RR = 0.817, 95% CI = 0.68-0.95) and prescription opioid injection (RR = 0.794, 95% CI = 0.66-0.93).

CONCLUSION

Among people who inject drugs in Montreal, Canada, injection drug use and receptive syringe-sharing appear to be more prevalent in the 2 days after versus before receiving income assistance. The odds and rate of individual-level increases in injection frequency appear to be positively associated with cocaine injection (versus injection of other substances) and unstable housing.

At the Intersection of Homeless Encampments and Heroin Addiction: Service Use Barriers, Facilitators, and Recommendations from the City of Philadelphia's Encampment Resolution Pilot

We provide an overview of the pilot and evaluation measures used for an independent evaluation of the Encampment Resolution Pilot (ERP) wherein the City of Philadelphia closed two homeless encampments in May 2018 and sought to assist those displaced by the closures with housing and treatment services. The evaluation used the Rapid Assessment, Response, and Evaluation method to collect qualitative findings on service use barriers and facilitators from open-ended interviews with people staying in the encampments (N = 27) and service providers (N = 10). We assessed how the ERP allowed providers to "push the system" by removing access barriers, and providing amenable, effective, and accessible housing and drug treatment services that led to more widely adopted best practices. However, there was a clear need for additional supportive services and aftercare for those exiting treatment. Providers also cited a need for more integrated medical and mental health services.

Surviving the housing crisis: Social violence and the production of evictions among women who use drugs in Vancouver, Canada

Single room accommodation (SRA) housing is among the only forms of accessible housing to marginalized women who use illicit drugs in many urban settings. However, SRA housing environments may create specific health and drug risks for women. Little research has examined the gendered mechanisms contributing to housing vulnerability for women who use drugs and the subsequent ways they aim to mitigate harm. This study examines the gendered vulnerabilities to, and harms stemming from, evictions from SRAs in Vancouver, Canada. Qualitative interviews were conducted with 56 people who use drugs who were recently evicted (past 60 days) from SRAs in Vancouver's Downtown Eastside neighbourhood, 19 of whom identified as women which informed this analysis. Participants were recruited by Peer Researcher Assistants for baseline and follow-up interviews three to six months later. Interview transcripts were analyzed thematically and interpreted by drawing on concepts of social violence. Findings underscore how gendered violence and forms of social control operationalized within SRAs normalized violence against women and restricted their agency. Surveillance mechanisms increased women's experiences of violence as they sought to evade such interventions. Post-eviction, women faced pronounced vulnerability to harm which reinforced their social and spatial marginality within a drug scene. Collectively, women's experiences within SRAs highlight how the hybrid forms of disciplinary mechanisms used within these housing environments significantly impacted women's experiences of harm. Greater attention to the impacts of housing and building policies on women who use drugs is needed to better address the morbidity and mortality of this population.

The experience of initiating injection drug use and its social context: a qualitative systematic review and thematic synthesis

BACKGROUND AND AIM

Understanding the experience of initiating injection drug use and its social contexts is crucial to inform efforts to prevent transitions into this mode of drug consumption and support harm reduction. We reviewed and synthesized existing qualitative scientific literature systematically to identify the socio-structural contexts for, and experiences of, the initiation of injection drug use.

METHODS

We searched six databases (Medline, Embase, PsychINFO, CINAHL, IBSS and SSCI) systematically, along with a manual search, including key journals and subject experts. Peer-reviewed studies were included if they qualitatively explored experiences of or socio-structural contexts for injection drug use initiation. A thematic synthesis approach was used to identify descriptive and analytical themes throughout studies.

RESULTS

From 1731 initial results, 41 studies reporting data from 1996 participants were included. We developed eight descriptive themes and two analytical (higher-order) themes. The first analytical theme focused on injecting initiation resulting from a social process enabled and constrained by socio-structural factors: social networks and individual interactions, socialization into drug-using identities and choices enabled and constrained by social context all combine to produce processes of injection initiation. The second analytical theme addressed pathways that explore varying meanings attached to injection initiation and how they link to social context: seeking pleasure, responses to increasing tolerance to drugs, securing belonging and identity and coping with pain and trauma.

CONCLUSIONS

Qualitative research shows that injection drug use initiation has varying and distinct meanings for individuals involved and is a dynamic process shaped by social and structural factors. Interventions should therefore respond to the socio-structural influences on injecting drug use initiation by seeking to modify the contexts for initiation, rather than solely prioritizing the reduction of individual harms through behavior change.

Syringe Sharing Among a Prospective Cohort of Street-Involved Youth: Implications for Needle Distribution Programs

The sharing of previously used syringes is associated with the transmission of Hepatitis C and HIV. This longitudinal study examines syringe borrowing and syringe lending within a prospective cohort of street-involved youth in Vancouver, Canada. From September 2005 to May 2014, data were collected from the At-Risk Youth Study, a cohort of street-involved youth age 14-26 at enrollment, and analyzed using generalized estimating equations. Among 505 participants, 142 (28.1%) reported syringe borrowing and 132 (26.1%) reported syringe lending during the study period. In separate multivariable analyses, having difficulty finding clean needles and homelessness were significantly associated with syringe borrowing (Adjusted Odds Ratio (AOR) = 2.28, 95% CI 1.66-3.12 and AOR = 1.52, CI 1.05-2.21, respectively) and syringe lending (AOR = 1.89, 95% CI 1.32-2.71 and AOR = 1.65, 95% CI 1.11-2.44, respectively) (all p values < 0.05). Findings highlight gaps in syringe access for vulnerable young injectors and suggest that service delivery for youth may be suboptimal. Further examination of how needle distribution efforts might be improved to better meet the needs of young people is warranted.

Self-care and risk reduction habits in older injection drug users with chronic wounds: a cross-sectional study

Background

We surveyed a population of injection drug users (IDUs) frequenting the mobile Baltimore City Needle Exchange Program (BNEP) to investigate self-care factors associated with chronic wounds, a significant cause of morbidity especially among older IDUs.

Methods

Participants ≥18 years old completed a survey regarding chronic wounds (duration ≥8 weeks), injection and hygiene practices. Study staff visually verified the presence of wounds. Participants were categorized into four groups by age and wound status. Factors associated with the presence of chronic wounds in participants ≥45 years were analyzed using logistic regression.

Results

Of the 152 participants, 19.7% had a chronic wound. Of those with chronic wounds, 18 were ≥45 years old (60.0%). Individuals ≥45 years old with chronic wounds were more likely to be enrolled in a drug treatment program (Odds ratio (OR) 3.4, 95% Confidence interval (CI) 1.0–10.8) and less likely to use cigarette filters when drawing up prepared drug (OR 0.2, 95% CI 0.03–0.7) compared to the same age group without chronic wounds. Compared to individuals <45 years old without chronic wounds, individuals ≥45 with a chronic wound were more likely to report cleaning reused needles with bleach (OR 10.7, 95% CI 1.2–93.9) and to use the clinic, rather than an emergency room, as a primary source of medical care (OR 3.4, 95% CI 1.1–10.4).

Conclusions

Older IDUs with chronic wounds have different, and perhaps less risky, injection and hygiene behaviors than their peers and younger IDUs without wounds in Baltimore City. Because of these differences, older IDUs with wounds may be more receptive to community-based healthcare and substance abuse treatment messages.

Differences in sociodemographic, drug use and health characteristics between never, former and current injecting, problematic hard-drug users in the Netherlands

Background

Injecting drug users are at increased risk for harmful effects compared to non-injecting drug users. Some studies have focused on differences in characteristics between these two groups (e.g., housing, overall health). However, no study has investigated the specific Dutch situation which in the last years has seen a decrease in homelessness among problematic hard-drug users and an increasing focus on physical health in low-threshold addiction care. The purpose of this study was to determine differences in sociodemographic, drug use and health characteristics between never-injecting (NIDUs), former-injecting (FIDUs) and current-injecting drug users (IDUs) and describe injecting practices.

Methods

A total of 202 problematic hard-drug users (NIDU = 64; FIDU = 76; IDU = 62) were recruited from 22 low-threshold care facilities, including drug consumption rooms, methadone maintenance treatment, heroin-assisted therapy, day shelter and/or night shelter, supported housing and day activity centres. Data were collected on-site through structured face-to-face interviews.

Results

Results indicate that IDUs represented a separate group of problematic hard-drug users, with distinct sociodemographic and drug use characteristics. Overall, IDUs appeared to be the group with least favourable characteristics (unstable housing/homelessness, illegal activities, polydrug use) and NIDUs appeared to have the most favourable characteristics (stable housing, help with debts, less polydrug use). The FIDU group lies somewhere in between. The three groups did not differ significantly in terms of health. Regarding injecting practices, results showed that majority of IDUs had injected drugs for over 10 years and IDUs injected heroin, cocaine, amphetamine and/or methadone in the past 6 months. Sharing syringes was not common. A quarter reported public injecting.

Conclusions

Unstable housing and homelessness are related to (former) injecting drug use, and stable housing is related to never-injecting drug use. Our study suggests that the number of ‘new’ IDUs is low. However, public injecting among IDUs is not uncommon and is associated with unstable housing. This emphasizes the potential of housing projects as a component of harm reduction measures. Therefore, prevention of (risks associated with) injecting drug use and supported housing programmes for problematic hard-drug users deserve the continuous attention of policymakers and professionals in low-threshold addiction care.

A qualitative study of the perceived effects of blue lights in washrooms on people who use injection drugs

Background

Blue lights are sometimes placed in public washrooms to discourage injection drug use. Their effectiveness has been questioned and concerns raised that they are harmful but formal research on the issue is limited to a single study. We gathered perceptions of people who use injection drugs on the effects of blue lights with the aim of informing harm reduction practice.

Methods

We interviewed 18 people in two Canadian cities who currently or previously used injection drugs to better understand their perceptions of the rationale for and consequences of blue lights in public washrooms.

Results

Participants described a preference for private places to use injection drugs, but explained that the need for an immediate solution would often override other considerations. While public washrooms were in many cases not preferred, their accessibility and relative privacy appear to make them reasonable compromises in situations involving urgent injecting. Participants understood the aim of blue lights to be to deter drug use. The majority had attempted to inject in a blue-lit washroom. While there was general agreement that blue lights do make injecting more difficult, a small number of participants were entirely undeterred by them, and half would use a blue-lit washroom if they needed somewhere to inject urgently. Participants perceived that, by making veins less visible, blue lights make injecting more dangerous. By dispersing public injection drug use to places where it is more visible, they also make it more stigmatizing. Despite recognizing these harms, more than half of the participants were not opposed to the continued use of blue lights.

Conclusions

Blue lights are unlikely to deter injection drugs use in public washrooms, and may increase drug use-related harms. Despite recognizing these negative effects, people who use injection drugs may be reluctant to advocate against their use. We attempt to reconcile this apparent contradiction by interpreting blue lights as a form of symbolic violence and suggest a parallel with other emancipatory movements for inspiration in advocating against this and other oppressive interventions.

Consumer and practitioner perceptions of the harm reduction approach in a community mental health setting

Harm reduction in community mental health settings can be effective in engaging persons with co-occurring disorders in services. In this qualitative study, personal interviews and grounded theory methods were used to explore the experiences of 21 mental health practitioners and 15 consumers with co-occurring disorders at a community mental health housing program that uses harm reduction. Results indicate that while harm reduction enhanced therapeutic alliances, ethical and emotional tensions between practitioners and consumers regarding their views on self-determination and tolerance of drug-related behaviors were also evident. These tensions are explored and implications for practice and education are provided.

The urgency of providing comprehensive and integrated treatment for substance abusers with HIV

Substance abuse is linked to many new cases of HIV infection. Barriers such as the myth that drug users cannot adhere to HIV/AIDS treatment block progress in curbing the spread of HIV in that population. In this article we explain the need to aggressively seek out high-risk, hard-to-reach substance abusers and to offer them HIV testing, access to treatment, and the necessary support to remain in treatment--both for HIV and for substance abuse. We summarize evidence showing that injection drug users can successfully undergo HIV treatment; that many substance abusers adhere to antiretroviral therapy as well as do people who don't inject drugs; and that injection drug users who undergo substance abuse treatment are more likely to obtain and stay in treatment for their HIV infection. This evidence makes a strong case for integrating substance abuse treatment with HIV treatment programs and providing substance abusers with universal access to HIV treatment. But an integrated strategy will require changes in the health care system to overcome lingering obstacles that inhibit the merging of substance abuse treatment with HIV programs.

Factors Associated with Treatment Compliance and its Effects on Retention among Participants in a Court-Mandated Treatment Program

Drug treatment court (DTC) programs have been implemented and promoted in American as well as Canadian judicial systems as an effective tool for reducing criminal recidivism rates. An evaluation of the program in Toronto revealed that the drug court participants' substance abuse and criminal behaviors are reduced while they are under the drug courts' jurisdiction, and to some extent recidivism is reduced after participants leave the program. However, while we know from the literature that there are positive effects of the program, the characteristics of drug-dependent offenders who benefit the most from the DTC are less clear. The main purpose of this study was to understand where the prediction from literature, that compliance determines success in treatment, fails. Thus, study participants were divided into two groups: 1) those who might normally be expected to not comply yet who do in the long run (unexpected retention, UR); and 2) those who might normally be expected to comply, but who do not (unexpected expulsions, UE). Discriminant function analysis showed that participants considered UR were subject to conditions of social disadvantage yet quite motivated; whereas UE participants had no housing concern, no indication of family problems, but had additional criminal justice involvement at an early stage of the program. Implications for strengthening DTCs as well as suggestions for future research in the drug treatment and drug court fields are discussed.
