López-Castro T, Sohler N, Riback L, Bravo G, Ohlendorf E, Ghiroli M, Fox AD. Posttraumatic stress disorder in people who use drugs: syringe services program utilization, treatment need, and preferences for onsite mental health care. Harm Reduct J 2024; 21:108. [PMID: 38824597 PMCID: PMC11143655 DOI: 10.1186/s12954-024-01019-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Accepted: 05/09/2024] [Indexed: 06/03/2024] Open
Abstract
BACKGROUND Syringe services programs (SSPs) are critical healthcare access points for people with opioid use disorder (OUD) who face treatment utilization barriers. Co-locating care for common psychiatric comorbidities, like posttraumatic stress disorder (PTSD), at SSPs may reduce harms and enhance the health of individuals with OUD. To guide the development of onsite psychiatric care at SSPs, we collected quantitative survey data on the prevalence of PTSD, drug use patterns, treatment experiences associated with a probable PTSD diagnosis, and attitudes regarding onsite PTSD care in a convenience sample of registered SSP clients in New York City. METHODS Study participants were administered the PTSD Checklist for the DSM-5 (PCL-5) and asked about sociodemographic characteristics, current drug use, OUD and PTSD treatment histories, and desire for future SSP services using a structured interview. Probable PTSD diagnosis was defined as a PCL-5 score ≥ 31. RESULTS Of the 139 participants surveyed, 138 experienced at least one potentially traumatic event and were included in the present analysis. The sample was primarily male (n = 108, 78.3%), of Hispanic or Latinx ethnicity (n = 76, 55.1%), and middle-aged (M = 45.0 years, SD = 10.6). The mean PCL-5 score was 35.2 (SD = 21.0) and 79 participants (57.2%) had a probable PTSD diagnosis. We documented frequent SSP utilization, significant unmet PTSD treatment need, and high interest in onsite PTSD treatment. CONCLUSIONS Study findings point to the ubiquity of PTSD in people with OUD who visit SSPs, large gaps in PTSD care, and the potential for harm reduction settings like SSPs to reach people underserved by the healthcare system who have co-occurring OUD and PTSD.

van Draanen J, Jamula R, Karamouzian M, Mitra S, Richardson L. Pathways connecting socioeconomic marginalization and overdose: A qualitative narrative synthesis. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2023; 113:103971. [PMID: 36822011 DOI: 10.1016/j.drugpo.2023.103971] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 01/30/2023] [Accepted: 02/01/2023] [Indexed: 02/25/2023]
Abstract
PURPOSE This qualitative narrative synthesis sought to identify pathways connecting socioeconomic marginalization (SEM) and overdose for people who use drugs. METHODS We included studies with qualitative examination of SEM and fatal and non-fatal overdose published in English between 2000 and 2021. Studies were systematically identified and screened by searching MEDLINE (Ovid), Embase (Ovid), PsycINFO (EBSCOhost), CINAHL (EBSCOhost), Google Scholar, Cochrane Central Registry of Controlled Trials (CENTRAL), and Cochrane Drug and Alcohol Group (CDAG) Specialized Registry, citations, and contacting experts. Risk of bias and quality assessments were performed using the Critical Appraisal Skills Programme checklist and the Confidence in the Evidence from Reviews of Qualitative Research approach. Data were synthesized using a thematic synthesis approach. RESULTS The primary search strategy found 5909 articles that met the initial screening criteria. The review and screening process led to a final dataset of 27 qualitative articles. The four key findings of this narrative synthesis revealed aspects of SEM which shaped drug poisoning risk for people who use drugs: (1) resource insufficiency, labor market exclusion and deindustrialization, (2) homelessness and housing, (3) policing, criminalization, and interactions with emergency services, and (4) gendered and racialized dimensions of inequality. Findings led to creating a typology that includes material, behavioral, psychological, social, and environmental pathways that contain multiple mechanisms connecting SEM to overdose. This review revealed reciprocal connections between overdose and SEM via institutional pathways with reinforcing mechanisms, and interrelationships present within and between pathways. Quality assessments indicated moderate confidence in three of four findings (Findings 2,3, and 4 above) and high confidence in one finding (Finding 1). CONCLUSION SEM is strongly linked to drug poisoning, and the mechanisms establishing these connections can be classified within four pathways. The interconnectedness of these mechanisms can lead to intensification of overdose risk and reinforcement of SEM itself.

Income generation and the patterning of substance use: A gender-based analysis. Drug Alcohol Depend 2021; 226:108862. [PMID: 34198138 PMCID: PMC8356895 DOI: 10.1016/j.drugalcdep.2021.108862] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 05/18/2021] [Accepted: 05/20/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND Previous research has demonstrated how income-generating activities among marginalized people who use drugs (PWUD)-including employment, income assistance, street-based activities, sex work, and illegal activities-can provide both benefit (e.g., additional income) and harm (e.g., violence, criminalization). However, little is known about gender differences in factors such as drug use patterns that are associated with income-generating activities among PWUD. METHODS Using data from prospective cohorts of HIV-positive and HIV-negative PWUD in Vancouver, Canada, we conducted exploratory gender-stratified analyses of associations between substance use patterns and income-generating activities, using generalized linear mixed-models. RESULTS Participants reported income sources as employment (23.4 %), income assistance (88.1 %), street-based activities (24.9 %), sex work (15.2 %), drug dealing (31.5 %), or other illegal activities (13.9 %). GLMM results showed gendered patterns of engagement in specific income-generating activities and some diverging patterns of substance use. For instance, men receiving income assistance were less likely to use opioids (Adjusted odds ratio(AOR) = 0.64; 95 % confidence interval(CI) = 0.50-0.82) and women engaged in sex work were more likely to use crack-cocaine (AOR = 2.74, 95 % CI = 2.22-3.37). However, results reflected primarily converging patterns of substance use between women and men across income-generating activities, particularly for drug dealing and other illegal activities. CONCLUSIONS Our results suggest that substance use patterns may be more closely associated with income generation context than gender. Given potential harms associated with some income generation activities, results highlight the need for further investigation of the social and structural context of income generation, its intersections with gender and substance use, and the expansion of low-threshold work opportunities.

Abstract
Molecularly imprinted polymers (MIP) consist of a molecular recognition technology with applicability in different areas, including forensic chemistry. Among the forensic applications, the use of MIP in biological fluid analysis has gained prominence. Biological fluids are complex samples that generally require a pre-treatment to eliminate interfering agents to improve the results of the analyses. In this review, we address the development of this molecular imprinting technology over the years, highlighting the forensic applications of molecularly imprinted polymers in biological sample preparation for analysis of stimulant drugs such as cocaine, amphetamines, and nicotine.

Abstract
BACKGROUND Socioeconomic marginalization (SEM) is an important but under-explored determinant of opioid overdose with important implications for health equity and associated public policy initiatives. This systematic review synthesizes evidence on the role of SEM in both fatal and non-fatal overdose among people who use opioids. METHODS Studies published between January 1, 2000 and March 31, 2018 were identified through searching electronic databases, citations, and by contacting experts. The titles, abstracts, citation information, and descriptor terms of citations were screened by two team members. Data were synthesized using the lumping technique. RESULTS A total of 37 studies met inclusion criteria and were included in the review, with 34 of 37 finding a significant association between at least one socioeconomic factor and overdose. The included studies contained variables related to eight socioeconomic factors: criminal justice system involvement, income, employment, social support, health insurance, housing/homelessness, education, and composite measures of socio-economic status. Most studies found associations in the hypothesized direction, whereby increased SEM was associated with a higher rate or increased likelihood of the overdose outcome measured. The review revealed an underdeveloped evidence base. CONCLUSIONS Nearly all reviewed studies found a connection between a socioeconomic variable and overdose, but more research is needed with an explicit focus on SEM, using robust and nuanced measures that capture multiple dimensions of disadvantage, and collect data over time to better inform decision making around opioid overdose.

Employment Cessation, Long Term Labour Market Engagement and HIV Infection Risk Among People Who Inject Drugs in an Urban Canadian Setting. AIDS Behav 2019; 23:3267-3276.

Abstract
The potential for changes in socio-economic status, such as employment exits, to increase HIV infection risk are not well examined among people who inject illicit drugs (PWID). We used longstanding cohort data from Vancouver, Canada, to longitudinally assess associations between employment cessation and outcomes with documented linkages to HIV infection risk among PWID. From 2005 to 2015, 1222 participants reported 1154 employment exits. Employment exits were significantly associated with transitions into unstable housing; moving to the inner-city; initiating informal, prohibited or illegal income generation; high risk drug use practices; and exiting methadone maintenance therapy. HIV infection rates were higher among participants with lower long-term labour market engagement. These findings suggest that employment cessation coincides with initiating exposure to aspects of socioeconomic marginalization and drug use associated with HIV infection risk. Support for employment retention that prevents poverty entrenchment and harmful drug use could contribute to HIV prevention measures for PWID.

Abstract
BACKGROUND Informal recycling refers to the street-based collection of discarded materials for reuse, resale, or return to a recycling facility for money. While qualitative research has explored experiences and perceptions of informal recycling, little is known about the scope and exposures associated with informal recycling among people who use drugs (PWUD). METHODS Using data from two prospective longitudinal cohorts of PWUD, we examined the prevalence of informal recycling and its association with social, structural and health risks, including criminal justice system involvement. RESULTS Between June 2010 and May 2015, of 1664 participants, 557 (33.5%) reported engaging in informal recycling during the study period. In multivariable generalised estimating equations (GEE) analyses, informal recycling was positively associated with injection drug use (Adjusted Odds Ratio (AOR) = 1.43, 95% Confidence Interval (CI) 1.21-1.68), public injection (AOR = 1.27, 95% CI 1.09-1.49), methamphetamine use (AOR = 1.35, 95% CI 1.05-1.72), difficulty finding harm reduction equipment (AOR = 1.16, 95% CI 1.02-1.32), and police interactions (AOR = 1.35, 95% CI 1.18-1.55). Sub-analyses revealed PWUD engaged in informal recycling were more likely to be told to move on, ticketed, stopped for jaywalking, and directed to services by police. CONCLUSIONS These findings suggest informal recycling as a situated practice for PWUD, with potential indications for higher-risk drug use, experiencing greater surveillance, and difficulty accessing health and addiction treatment services. This research highlights the significance of the broader risk environment and the need for health-promoting policies for socioeconomically marginalised PWUD engaged in informal recycling.

Abstract
BACKGROUND Costs attributable to criminal activity are a major component of the economic burden of substance use disorders, yet there is a paucity of empirical evidence on this topic. Our aim was to estimate the costs of crime associated with different forms and intensities of stimulant use. METHODS Retrospective cohort study, including individuals from three prospective cohorts in Vancouver, Canada, measured biannually (2011-2015), reporting stimulant use at baseline assessment. Monthly crime costs included policing, court, corrections, and criminal victimization (2016 CAD). We estimated monthly crime costs associated with mutually exclusive categories of crack, cocaine, methamphetamine, and polystimulant use, stratified by daily/non-daily use, relative to stimulant abstinence, as well as the independent effects of treatment (opioid agonist (OAT) and other addiction treatment). We used a two-part model, capturing the probability of criminal activity and costs of crime with generalized linear logistic and gamma regression models, respectively, controlling for age, gender, education, homelessness, mental health issues, employment, prior incarceration, alcohol and opioid use. RESULTS The study sample included 1599 individuals (median age 39, 65.9% male) assessed over 5299 biannual interviews. Estimates of associated monthly crime costs ranged from $5449 [95% C.I.: $2180, $8719] for non-daily polystimulant use, to $8893 [$4196, $13,589] for daily polystimulant use. Cost differences between daily/non-daily use, injection/non-injection, and stimulant type were not statistically significant. Drug treatment was not associated with lower monthly crime costs in our sample. CONCLUSIONS Substantial crime-related costs were associated with stimulant use, emphasizing the urgency for development and implementation of efficacious treatment regimens.

Abstract
Introduction People who inject drugs (PWID) are highly exposed to drug-dealing networks. In Colombia, a recent dramatic increase in drug consumption has been reported. However, involvement of PWID in drug dealing, their demographics, and drug using behaviors has not been studied. Methods A cross-sectional study involving 1,099 PWID recruited by Respondent Driven-Sampling in five Colombian cities was conducted in 2014. Correlates of demographic characteristics, drug dealing, and injection behaviors were examined by multivariate analysis, and a binary logistic regression model. Results Drug-dealing PWID were predominantly male (86%) with a mean age of 26 years. 56% of participants-of whom 64% had low familial socioeconomic status-had been involved in drug dealing in the previous six months. Compared to non-drug-dealing PWID, drug-dealing PWID reported higher daily injection rate (AOR: 1.3), higher odds of injection equipment confiscation by the police (AOR: 1.4), and were less likely to pay for the drugs they injected (AOR: 0.6). Conclusions Involvement of Colombian PWID in drug dealing was higher than previously reported, and drug-dealing PWID presented sociodemographic vulnerabilities and risky injection practices. Addressing these findings may lead to effective policy design and implementation, decreased drug-dealing involvement, harm reduction, and consumption prevention.

Abstract
INTRODUCTION Socioeconomically marginalized people who use illicit drugs (PWUD) often engage in alternative income generating activities to meet their basic needs. These activities commonly carry a number of health and social risks, which may prompt some PWUD to consider addiction treatment to reduce their drug use or drug-related expenses. We sought to determine whether engaging in certain forms of income generation was independently associated with self-reported need for addiction treatment among a cohort of PWUD in Vancouver, Canada. METHODS Data from two prospective cohorts of PWUD in Vancouver were used in generalized estimating equations to identify factors associated with self-reported need for addiction treatment, with a focus on income generating activities. RESULTS Between June 2013 and May 2014, 1285 respondents participated in the study of whom 483 (34.1%) were female and 396 (30.8%) indicated that they needed addiction treatment. In final multivariate analyses, key factors significantly and positively associated with self-reported need for addiction treatment included engaging in illegal income generating activities (adjusted odds ratio [AOR]=1.96, 95% confidence interval [CI}: 1.11-3.46); sex work (AOR=1.61, 95% CI: 1.05-2.47), homelessness (AOR=1.65, 95% CI: 1.22-2.25); and recent engagement in counselling (AOR=1.85, 95% CI: 1.40-2.44). DISCUSSION Our results suggest that key markers of socioeconomic marginalization are strongly linked with a stated need for addiction treatment. These findings underscore the need to provide appropriate and accessible addiction treatment access to marginalized PWUD and to consider alternative approaches to reduce socioeconomic disadvantage.

Soc Sci Med 2016; 171:94-102. [PMID: 27842998 PMCID: PMC5127399 DOI: 10.1016/j.socscimed.2016.11.006] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2016] [Revised: 11/02/2016] [Accepted: 11/03/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND The monthly disbursement of social assistance (SA) payments to people who use illicit drugs (PWUD) has been temporally associated with increases in drug-related harm. Yet, whether SA receipt changes drug use intensity compared to levels of use at other times in the month has not been established. We therefore examined this relationship among PWUD in Vancouver, Canada (2005-2013). METHODS Data were derived from prospective cohorts of HIV-positive and HIV-negative PWUD. Every six months, participants were asked about their illicit drug use during the last 180 days and the past week. We determined whether SA receipt occurred within the assessment's one-week recall period. We employed generalized estimating equations controlling for confounders to examine the relationship between SA receipt and the change in drug use intensity, defined as a 100% increase in the average times per day a given drug was used in the last week compared to the previous 6 months. We tested the robustness of this relationship by stratifying analyses by whether individuals primarily used stimulants, illicit opioids or engaged in polydrug use and examining the timing of SA receipt relative to date of assessment. RESULTS Our study included 2661 individuals (median age 36, 32% female) with 1415 (53.2%) reporting SA receipt occurring within the one-week recall period of the assessment at least once. SA receipt was independently associated with intensified drug use (Adjusted Odds Ratio [AOR]: 1.79; 95% Confidence Interval [CI]: 1.53, 2.09), and remained significant when stratified by primary use of stimulants (AOR: 1.87; 95% CI: 1.54, 2.26), opioids (AOR: 1.96; 95% CI: 1.23, 3.13) and polydrug use (AOR: 1.53; 95% CI: 1.11, 2.10). CONCLUSION We found a temporal association between SA receipt and drug use intensification. While the health and social benefits of SA are significant, these findings suggest that alternative disbursement strategies, such as staggered or smaller and more frequent SA payments may be able to mitigate drug-related harm. Alternatives should be tested rigorously.

Meaningful engagement of people living with HIV who use drugs: methodology for the design of a Peer Research Associate (PRA) hiring model. Harm Reduct J 2016; 13:26. [PMID: 27717364 PMCID: PMC5054577 DOI: 10.1186/s12954-016-0116-z] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2016] [Accepted: 09/24/2016] [Indexed: 11/25/2022] Open
Abstract
Background Community-based HIV, harm reduction, and addiction research increasingly involve members of affected communities as Peer Research Associates (PRAs)—individuals with common experiences to the participant population (e.g. people who use drugs, people living with HIV [PLHIV]). However, there is a paucity of literature detailing the operationalization of PRA hiring and thus limited understanding regarding how affected communities can be meaningfully involved through low-barrier engagement in paid positions within community-based participatory research (CBPR) projects. We aim to address this gap by describing a low-threshold PRA hiring process. Results In 2012, the BC Centre for Excellence in HIV/AIDS and the Dr. Peter AIDS Foundation collaborated to develop a mixed-method CBPR project evaluating the effectiveness of the Dr. Peter Centre (DPC)—an integrative HIV care facility in Vancouver, Canada. A primary objective of the study was to assess the impact of DPC services among clients who have a history of illicit drug use. In keeping with CBPR principles, affected populations, community-based organizations, and key stakeholders guided the development and dissemination of a low-barrier PRA hiring process to meaningfully engage affected communities (e.g. PLHIV who have a history of illicit drug use) in all aspects of the research project. The hiring model was implemented in a number of stages, including (1) the establishment of a hiring team; (2) the development and dissemination of the job posting; (3) interviewing applicants; and (4) the selection of participants. The hiring model presented in this paper demonstrates the benefits of hiring vulnerable PLHIV who use drugs as PRAs in community-based research. Conclusions The provision of low-barrier access to meaningful research employment described herein attempts to engage affected communities beyond tokenistic involvement in research. Our hiring model was successful at engaging five PRAs over a 2-year period and fostered opportunities for future paid employment or volunteer opportunities through ongoing collaboration between PRAs and a diverse range of stakeholders working in HIV/AIDS and addictions. Additionally, this model has the potential to be used across a range of studies and community-based settings interested in meaningfully engaging communities in all stages of the research process.

THE AMERICAN JOURNAL OF DRUG AND ALCOHOL ABUSE 2016; 42:507-512. [PMID: 27315200 PMCID: PMC5055453 DOI: 10.1080/00952990.2016.1186684] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/29/2015] [Revised: 04/28/2016] [Accepted: 05/03/2016] [Indexed: 10/21/2022]
Abstract
BACKGROUND Street-involved youth who use drugs may have limited income-generation options and are known to commonly become immersed in illicit drug markets to generate funds. However, little attention has been given to factors that may drive drug dealing initiation among this vulnerable population. OBJECTIVES This longitudinal study examines drug dealing initiation among street-involved youth. METHODS Data were derived from the At-Risk Youth Study from September 2005 to November 2014; a prospective cohort of 194 street-involved youth who use drugs aged 14-26, in Vancouver, Canada. Extended Cox model was used to identify factors independently associated with time to first drug dealing. RESULTS Among street-involved youth who had never dealt drugs at baseline, 56 (29%) individuals initiated drug dealing during the study period for an incidence density of 13.0 per 100 person-years (95% confidence interval [CI]: 9.9-17.2). In multivariable Cox regression analysis, male gender (adjusted hazard ratio [AHR] = 1.90, 95% CI: 1.06-3.42), homelessness (AHR = 1.88, 95% CI: 1.05-3.35), crystal methamphetamine use (AHR = 2.48, 95% CI: 1.47-4.20), and crack cocaine use (AHR = 2.35, 95% CI: 1.38-4.00) were positively and independently associated with initiating drug dealing. CONCLUSION Homelessness and stimulant drug use were key risk factors for drug dealing initiation among street-involved youth. Findings indicate that evidence-based and innovative interventions, including youth-centric supportive housing, low threshold employment programs, and stimulant addiction treatment should be implemented and evaluated as strategies to help prevent this vulnerable population from engaging in risky illegal income generation practices.

Abstract
BACKGROUND Despite the multitude of public health and community harms associated with crack cocaine use, little is known about factors associated with smoking crack in public and related risks such as rushed public crack smoking. METHODS Data were derived from two prospective cohort studies of people who use illicit drugs in Vancouver, Canada between 2010 and 2014. Multivariable generalized estimating equations were used to identify the prevalence and correlates of public crack smoking and rushed public crack smoking. RESULTS In total, 1085 participants who had smoked crack in the prior six months were eligible for the analysis, of which 379 (34.9 %) reported always or usually smoking crack in public in the previous six months at some point during the study period. Factors positively and independently associated with public crack smoking included public injection drug use (adjusted odds ratio [AOR]: 5.42, 95 % confidence interval [CI]: 3.76-7.82), homelessness (AOR: 3.48, 95 % CI: 2.77-4.36), at least daily crack use (AOR: 2.69, 95 % CI: 2.19-3.31), crack pipe sharing (AOR: 1.98, 95 % CI: 1.60-2.46), drug dealing (AOR: 1.59, 95 % CI: 1.30-1.94), recent incarceration (AOR: 1.47, 95 % CI: 1.09-1.98), noticing police presence when buying or using drugs (AOR: 1.30, 95 % CI: 1.06-1.60), and younger age (AOR: 1.03, 95 % CI: 1.01-1.04). Rushed public crack smoking, which was reported by 216 (28.8 %) of 751 participants who had smoked crack in public at least once during the study period, was positively and independently associated with homelessness (AOR: 2.61, 95 % CI: 1.96-3.49), at least daily crack use (AOR: 1.48, 95 % CI: 1.11-1.98), crack pipe sharing (AOR: 1.44, 95 % CI: 1.10-1.89), drug dealing (AOR: 1.39, 95 % CI: 1.04-1.86), and younger age (AOR: 1.02, 95 % CI: 1.01-1.04). CONCLUSIONS A high prevalence of public crack smoking and rushed public crack smoking was observed in this setting. These findings point to the need for implementing and evaluating evidence-based public health interventions, such as supervised inhalation facilities, to reduce the risks and harms associated with smoking crack in public.

PLoS One 2015; 10:e0141594. [PMID: 26509447 PMCID: PMC4624845 DOI: 10.1371/journal.pone.0141594] [Citation(s) in RCA: 55] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2015] [Accepted: 10/09/2015] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Leaving hospital against medical advice (AMA) is common among people who use illicit drugs (PWUD) and is associated with severe health-related harms and costs. However, little is known about the prevalence of and factors associated with leaving AMA among PWUD. METHODS Data were collected through two Canadian prospective cohort studies involving PWUD between September 2005 and July 2011 and linked to a hospital admission/discharge database. Bivariable and multivariable generalized estimating equations were used to examine factors associated with leaving hospital AMA among PWUD who were hospitalized. RESULTS Among 488 participants who experienced at least one hospitalization, 212 (43.4%) left the hospital AMA at least once during the study period. In multivariable analyses, factors positively and significantly associated with leaving hospital AMA included: unstable employment (AOR = 1.92; 95% confidence interval [CI]: 1.22-3.03); recent incarceration (AOR = 1.63; 95%CI: 1.07-2.49); ≥ daily heroin injection (AOR = 1.49; 95%CI: 1.05-2.11); and younger age per year younger (adjusted odds ratio [AOR] = 1.04; 95%CI: 1.02-1.06). CONCLUSIONS We found a substantial proportion of PWUD in this setting left hospital AMA and that various markers of risk and vulnerability were associated with this phenomenon. Our findings highlight the need to address substance abuse issues early following hospital admission. These findings further suggest a need to develop novel interventions to minimize PWUD leaving hospital prematurely.
