Treatment barriers among individuals with co-occurring substance use and mental health problems: Examining gender differences

Seeking Safety for women in incarceration: a systematic review

PURPOSE

Seeking Safety is an evidence-based treatment for individuals with comorbid posttraumatic stress disorder and substance use disorder. This treatment shows promise to address the unique, unmet needs of women in prison. The current systematic literature review aims to highlight several critical gaps in research on Seeking Safety in forensic settings that need to be filled before Seeking Safety can be implemented in a widespread manner.

METHODS

PsycINFO, PubMed and Google scholar databases were used to identify studies that were published in English, included women in forensic settings, and incorporated Seeking Safety treatment. A total of seven studies met review criteria. The quality of studies was assessed with the mixed methods appraisal tool.

RESULTS

High risk of contamination, inclusion of small, predominantly White samples, high attrition rates, need for dose-response testing, and lack of follow-up data currently limit the ability to assess the efficacy of Seeking Safety in forensic settings. In addition, there is a lack of research on Seeking Safety's ability to reduce symptoms of substance use disorder for incarcerated women and further cultural adaptation may be needed.

CONCLUSION

Seeking Safety has the potential to address the underlying causes of incarceration for justice-involved women, but additional research addressing these identified gaps is needed to facilitate more widespread implementation.

Gender differences in structural and attitudinal barriers to mental healthcare in UK Armed Forces personnel and veterans with self-reported mental health problems

PURPOSE

Structural and attitudinal barriers often hinder treatment-seeking for mental health problems among members of the Armed Forces. However, little is known about potential gender differences in structural and attitudinal barriers among members of the UK Armed Forces. The current study aimed to explore how men and women differ in terms of these barriers to care among a sample of UK Armed Forces personnel and veterans with self-reported mental health problems.

METHODS

Currently serving and ex-serving members of the UK Armed Forces who self-reported a mental health problem were invited to participate in a semi-structured phone interview on mental health and treatment-seeking. The final sample included 1448 participants (1229 men and 219 women). All participants reported on their current mental health, public stigma, self-stigma, and barriers to mental healthcare.

RESULTS

Overall, men and women reported similar levels of both structural and attitudinal barriers, with no significant differences detected. The highest scores for both men and women were observed in attitudinal barriers relating to self-stigma domains, which encapsulate internalised attitudes and beliefs about mental illness and treatment.

CONCLUSIONS

Findings suggest that anti-stigma campaigns can be targeted simultaneously at both men and women within the Armed Forces. In particular, targeting self-stigma may be beneficial for health promotion campaigns.

Interventions to reduce self-stigma in people who use drugs: A systematic review

BACKGROUND

Substance use stigma is a key barrier to treatment and harm reduction engagement among people who use drugs (PWUD). Previous systematic reviews have focused on interventions to reduce stigma in healthcare providers and the public; less is known about interventions to address self-stigma among PWUD. The purpose of this review is to evaluate the evidence for substance use self-stigma reduction interventions.

METHODS

We reviewed English-language studies published between 2011 and 2023 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO #CRD42022321305). We searched seven bibliographic databases (PubMed; SCOPUS; APA PsycInfo; CINAHL; Social Work Abstracts; Sociological Abstracts; ProQuest Dissertations & Theses). This review included studies if 1) they evaluated the effectiveness of a psychosocial intervention, 2) participants were PWUD, 3) authors reported self-stigma as a primary outcome, 4) the study design was experimental or quasi-experimental. We reviewed, interpreted and reported intervention characteristics and effectiveness using narrative synthesis. We assessed study quality with the Downs & Black checklist.

RESULTS

Among 1195 screened studies, 15 met the inclusion criteria (N = 2280 PWUD). We categorized the interventions according to three approaches: psychotherapeutic (n = 8), psychoeducational (n = 5), and multimodal (n = 2). Most interventions were delivered in clinical settings (n = 11) and in a group format (n = 13). Study quality was fair-to-good and included nine randomized controlled trials (RCTs) and six quasi-experiments. Measurement heterogeneity was high, with 11 different stigma-related scales used across the 15 studies. Eleven studies showed significant favorable effects in at least one stigma measure. Six of these demonstrated positive effects in all stigma measures. Evidence was mixed for all three intervention categories; however, Acceptance and Commitment Therapy, a form of group psychotherapy, demonstrated effectiveness in four of five RCTs incorporating this approach.

CONCLUSIONS

Overall, there is promising evidence for the effectiveness of substance use self-stigma interventions, although more studies are needed to determine which approaches are most effective. Consistent conceptualization and measurement of self-stigma across studies will improve comparability in future intervention trials. Current offerings are largely limited to clinical settings and group-based formats; self-help interventions, available for other stigmatized conditions, could be developed to serve the majority of PWUD not engaged in treatment.

Sex and Gender Differences in Co-Occurring Alcohol Use Disorder and PTSD

Purpose of Review

Research demonstrates a strong association between alcohol use disorder (AUD) and posttraumatic stress disorder (PTSD). However, less is known about sex- and gender-based differences among individuals with AUD + PTSD. This narrative review examines recent literature in this area and aims to be a reference for future research endeavors.

Recent Findings

Extant literature shows that intertwining biological systems increase females' risk of developing PTSD and experiencing more adverse effects from AUD compared to males. Sex-based physiological differences further interact with gendered sociocultural environments to influence the risk of AUD + PTSD. Emerging research suggests potential gender-specific pathways between PTSD, coping, and AUD which may inform prevention and treatment. However, barriers to care are often gender-specific and tailored approaches are needed to improve reach and uptake.

Summary

Additional research is needed to examine intersectional and contextual factors that synergistically influence sex/gender differences in AUD + PTSD, particularly beyond cisgender identities, and mechanisms of action.

A mixed-methods comparison of gender differences in alcohol consumption and drinking characteristics among patients in Moshi, Tanzania

Excessive alcohol use stands as a serious threat to individual and community well-being, having been linked to a wide array of physical, social, mental, and economic harms. Alcohol consumption differs by gender, a trend seen both globally and in Moshi, Tanzania, a region with especially high rates of intake and few resources for alcohol-related care. To develop effective gender-appropriate treatment interventions, differences in drinking behaviors between men and women must be better understood. Our study aims to identify and explore gender-based discrepancies in alcohol consumption among Kilimanjaro Christian Medical Center (KCMC) patients. A systematic random sampling of adult patients presenting to KCMC's Emergency Department (ED) or Reproductive Health Center (RHC) was conducted from October 2021 until May 2022. Patients answered demographic and alcohol use-related questions and completed brief surveys, including the Alcohol Use Disorder Identification Test (AUDIT). Through purposeful sampling, 19 individuals also participated in in-depth interviews (IDIs) that focused on identifying gender differences in alcohol use. Quantitative data was analyzed in RStudio through descriptive frequencies, proportions, ANOVA, and Chi-squared tests, while IDIs were analyzed in Nvivo following a grounded theory approach. During the 8-month data collection timeline, 676 patients were enrolled. Men and women patients at KCMC's ED and RHC were found to have significant differences in their alcohol use behaviors. For our quantitative data, this included lower average AUDIT scores among women (average [SD] AUDIT scores were 6.76 [8.16] among ED men, 3.07 [4.76] among ED women, and 1.86 [3.46] among RHC women). A subsequent IDI analysis revealed greater social restrictions around women's drinking and more secretive alcohol use behaviors for where and when women would drink. For men, excess drinking was normalized within Moshi, tied to men's social interactions with other men, and generally motivated by stress, social pressure, and despair over lack of opportunity. Significant gender differences in drinking behaviors were found, primarily influenced by sociocultural norms. These dissimilarities in alcohol use suggest that future alcohol-related programs should incorporate gender in their conceptualization and implementation.

A Mixed-Methods Comparison of Gender Differences in Alcohol Consumption and Drinking Characteristics among Patients in Moshi, Tanzania

Background

Excessive alcohol use stands as a serious threat to individual and community well-being, having been linked to a wide array of physical, social, mental, and economic harms. Alcohol consumption differs by gender, a trend seen both globally and in Moshi, Tanzania, a region with especially high rates of intake and few resources for alcohol-related care. To develop effective gender-appropriate treatment interventions, differences in drinking behaviors between men and women must be better understood. Our study aims to identify and explore gender-based discrepancies in alcohol consumption among Kilimanjaro Christian Medical Center (KCMC) patients.

Methods

A systematic random sampling of adult patients presenting to KCMC's Emergency Department (ED) or Reproductive Health Center (RHC) was conducted from October 2020 until May 2021. Patients answered demographic and alcohol use-related questions and completed brief surveys including the Alcohol Use Disorder Identification Test (AUDIT). Through purposeful sampling, 19 subjects also participated in in-depth interviews (IDIs) focused on identifying gender differences in alcohol use.

Results

During the 8-month data collection timeline, 655 patients were enrolled. Men and women patients at KCMC's ED and RHC were found to have significant differences in their alcohol use behaviors including lower rates of consumption among women, (average [SD] AUDIT scores were 6.76 [8.16] among ED men, 3.07 [4.76] among ED women, and 1.86 [3.46] among RHC women), greater social restrictions around women's drinking, and more secretive alcohol use behaviors for where and when women would drink. For men, excess drinking was normalized within Moshi, tied to men's social interactions with other men, and generally motivated by stress, social pressure, and despair over lack of opportunity.

Significant gender differences in drinking behaviors were found, primarily influenced by sociocultural norms. These dissimilarities in alcohol use suggest that future alcohol-related programs should incorporate gender in their conceptualization and implementation.

Mental Health and Recovery Needs Among Women Substance Use Disorder Treatment Clients With Stalking Victimization Experiences

This study examined mental health and recovery needs at substance use disorder (SUD) program entry and at follow-up ( n = 2064) among: (1) women with no stalking victimization; (2) women with lifetime stalking victimization experiences; and (3) women with recent stalking victimization experiences (within 12 months of program entry). Stalking can be defined as a repeated pattern of behavior that creates fear or concern for safety or extreme emotional distress in the target. Women who experienced any stalking victimization, and particularly recent stalking victimization at program entry, had more recovery needs and increased mental health symptoms. At follow-up, women with any stalking victimization experiences continued to have more recovery needs with few differences between the lifetime and recent stalking victimization groups. Stalking victimization experiences were significantly associated with depression and anxiety symptoms in the multivariate analysis. Addressing stalking victimization during SUD treatment may be important to facilitate recovery.

Qualitative description of outreach and engagement in perinatal substance treatment in Finland

BACKGROUND

Women with perinatal substance problems experience a multitude of barriers to care. They have specific early intervention needs, they endure societal stigma, and both substances and mental health issues influence the way they navigate within support and treatment systems. Early interventions for women with perinatal substance problems are underresearched contexts. The aim of the study is to describe building relationships and engagement within an outreach and low threshold service encounter tailored for pregnant women with SUD (substance use disorder).

METHODS

The data consist of online written narratives from 11 workers involved in the program and feedback from 504 families in the recovery process comprising 228 open-ended answers. The data were analyzed with a thematic analysis.

RESULTS

The programs are characterized by flexibility and the implementation of inclusive ways to approach families. The themes for enhancing relationships and engagement within outreach and low threshold programs are Acceptance and attitude: a sensitive approach of approval; flexibility within strictness to allow for diversity and individuality; availability and space to ensure a trustful atmosphere; negotiating via doing to build connections; and everyday life changes: imagining recovery. The themes represent the need of being available, focusing on the worker's attitudes and building connections by doing together, and visioning recovery together.

CONCLUSIONS

The study results can add to the understanding of SUD outreach and low threshold work during pregnancy. The elements described in this study need further theoretical development, research and critical assessment. Building relationships during pregnancy were characterized by connecting within everyday life situations and supporting the development of an attachment relationship between the baby and the parents. To promote recovery, a comprehensive approach in which substance-related issues and mental health conditions are interconnected can be favored. Engaging early on during pregnancy might enhance success during future rehabilitation.

A systematic review of gender-responsive and integrated substance use disorder treatment programs for women with co-occurring disorders

Background: Integrated and gender-responsive interventions, designed to target co-occurring substance use and psychiatric disorders in women, may be effective in addressing gender-specific challenges.Objectives: This systematic review aims to identify integrated gender-responsive substance use disorder treatments for women, summarize evaluations of these treatments, and address gaps in the literature.Methods: We searched PsycINFO, PubMed, and MEDLINE on September 24, 2021, and March 10, 2022. Included articles were randomized-controlled trials, secondary analyses of naturalistic studies, or open-label studies of integrated and gender-responsive treatments from any year that assessed both substance use and mental health/trauma outcomes.Results: We identified N = 24 studies (participants = 3,396; 100% women) examining Seeking Safety, Helping Women Recover and Beyond Trauma, A Woman's Path to Recovery, Modified Trauma Recovery and Empowerment Model (TREM), Breaking the Cycle, VOICES, Understanding and Overcoming Substance Misuse, Women's Recovery Group, Female Specific Cognitive Behavioral Therapy, and Moment by Moment in Women's Recovery. Across treatments there were significant improvements over time; Seeking Safety, Helping Women Recover, and TREM were associated with significantly better substance use and mental health outcomes relative to the comparison groups.Conclusions: Integrated gender-responsive treatments are a promising approach to treating women with co-occurring substance use and mental health concerns, and broad clinical implementation stands to benefit women. However, there remains a lack of studies evaluating substance use treatments in women with severe mental illness (e.g., psychotic-spectrum disorders) who differ in their needs and capacity.

Non-engagement in substance use treatment among women with an unmet need for treatment: A latent class analysis on multidimensional barriers

BACKGROUND

Women with substance use disorders experience multifaceted barriers in accessing substance use treatment. Little is known about how these barriers may aggregate. Using a person-centered approach, this study evaluates patterns of treatment barriers and the factors associated with experiencing distinct sets of barriers among women.

METHODS

Data were from the NSDUH (2015-2019). 461 adult women with an unmet need for substance use treatment in the last year reported on 14 treatment barriers. Latent class analysis examined classes of barriers; multinomial logistic regression assessed predictors of class membership.

RESULTS

Three classes were identified: just not ready to abstain (71.2%), logistical barriers and stigmatization (18.2%), and barriers across all dimensions (10.6%). Higher education (aOR:1.94, p = 0.03) and psychological distress (aOR:2.19, p = 0.02) predicted higher odds-and identifying as African American predicted lower odds (aOR:0.17, p = 0.02)-of belonging to the "Logistics and Stigma Barriers" class relative to the "Just Not Ready" class. Similarly, higher education (aOR: 2.57, p = 0.02) and having children (aOR:2.28, p = 0.03) predicted higher odds-and marriage predicted lower odds (aOR:0.22, p = 0.02)-of belonging to the "High and Diverse Barriers" class relative to the "Just Not Ready" class. Having children predicted higher odds (aOR: 2.93, p = .02), and marriage predicted lower odds (aOR:0.19, p = 0.02) of belonging to the "High and Diverse Barriers" class relative to the "Logistics and Stigma" class.

CONCLUSION

A lack of readiness to abstain, socioeconomic circumstances, and family obligations are main barriers to SUD treatment among women. Interventions incorporating motivational interviewing, family systems, and social networks are needed.

Opioid relapse and MOUD outcomes following civil commitment for opioid use

INTRODUCTION

Opioid use disorder (OUD) continues to present a major public health problem in the United States. Civil commitment for substance use is one mandatory form of treatment for severe opioid use that has become increasingly available in recent years, but empirical data on this approach are lacking. This study examines clinical outcomes of civil commitment in a sample of adults with severe opioid use.

METHODS

Participants were 121 persons with opioid use who were interviewed at the point of entry into civil commitment, then followed for 12 weeks after their release.

RESULTS

Prior to civil commitment, this sample exhibited serious substance use characteristics (including high rates of illicit opioid use, other substance use, and injection drug use), as well as mental health problems (diagnoses of depression and anxiety disorders). During follow-up, approximately 41 % of the sample reported at least one illicit opioid use day. More than 64 % of the sample reported at least one day of medication for opioid use disorder (MOUD) receipt, and participants were significantly less likely to use illicit opioids on days that they received MOUDs. No participants died during the follow-up period.

CONCLUSIONS

In this sample of persons with severe opioid use, clinical outcomes of civil commitment included illicit opioid relapse as well as varying levels of MOUD uptake. Civil commitment may be a viable method for short-term prevention of overdose for a subset of this vulnerable patient population.

Current and emerging pharmacotherapies for opioid dependence treatments in adults: a comprehensive update

INTRODUCTION

Opioid use disorder (OUD) is characterized by compulsive opioid seeking and taking, intense drug craving, and intake of opioids despite negative consequences. The prevalence of OUDs has now reached an all-time high, in parallel with peak rates of fatal opioid-related overdoses, where 15 million individuals worldwide meet the criteria for OUD. Further, in 2020, 120,000 opioid-related deaths were reported worldwide with over 75,000 of those deaths occurring within the United States.

AREAS COVERED

In this review, we highlight pharmacotherapies utilized in patients with OUDs, including opioid replacement therapies, and opioid antagonists utilized for opioid overdoses and deterrent of opioid use. We also highlight newer treatments, such as those targeting the neuroimmune system, which are potential new directions for research given the recently established role of opioids in activating neuroinflammatory pathways, as well as over the counter remedies, including kratom, that may mitigate withdrawal.

EXPERT OPINION

To effectively treat OUDs, a deeper understanding of the current therapeutics being utilized, their additive effects, and the added involvement of the neuroimmune system are essential. Additionally, a complete understanding of opioid-induced neuronal alterations and therapeutics that target these abnormalities - including the neuroimmune system - is required to develop effective treatments for OUDs.

A recreational group intervention based on Relational Cultural Theory for women experiencing substance use disorders in Australia: A protocol

Gender differences exist in the progression, initiation and maintenance of substance use disorders (SUDs). Women encounter unique barriers to accessing treatment for their SUDs and commonly report higher perceptions of stigma around their substance use. Currently, there is a paucity of women-specific treatment options that address their perception of stigma and shame regarding SUDs. The Women of the West (WOW) programme is a pilot study that explores the subjective acceptability and feasibility of participating in a recreational and relational skill development group for women with SUDs. The pilot study adopts qualitative research methods including focus groups and interviews with ten participants who self-identify as women experiencing SUDs and two programme facilitators. The programme's primary aim is to promote participants' relational skills with peers in an enjoyable, and therapeutic environment. It is anticipated as participants develop their relational skills with peers, their sense of stigma regarding their SUDs and social isolation will decrease. Ultimately this can promote their long-term recovery from SUDs and overall well-being. Findings from this study will provide direction for future programme development and treatment services seeking to promote better outcomes for women with SUDs.

Prevalence and Differential Profile of Patients with Substance Use Disorder Who Have Suffered Physical and/or Sexual Abuse

Patients with substance use disorder (SUD) who undergo treatment present a high prevalence of lifetime physical and/or sexual abuse. Studies about this phenomenon and the specific needs of patients with a history of abuse must be carried out to tailor treatment programs. The first goal of this article was to determine the prevalence of physical and/or sexual abuse among patients with SUD, and the second goal was to analyze the specific characteristics of these patients. A sample of 418 subjects was assessed to achieve the first goal and 104 subjects (52 with and 52 without a history of physical and/or sexual abuse) were examined to reach the second goal. All patients sought treatment for SUD in two Spanish clinical centers. The results showed that 15.5% of the sample had a history of physical and/or sexual abuse (42.3% of women and 9.9% of men). Patients with a history of abuse presented a higher need for SUD treatment in family and psychiatric areas and more psychopathological symptoms than patients without a history of abuse. According to this more serious profile, a patient-centered intervention considering the history of abuse is recommended. This will allow the specific needs of these patients to be met, thus improving SUD treatment success.

Why language matters in alcohol research: Reducing stigma

BACKGROUND

The use of pejorative or stigmatizing language to describe individuals with alcohol and drug use disorders adversely affects treatment seeking, quality of care, and treatment outcomes. In 2015, the International Society of Addiction Journal Editors released terminology guidelines that recommended against the use of words that contribute to stigma against individuals with an addictive disorder. This study examined the use of stigmatizing language in National Institutes of Health (NIH)-funded research and reviews published by the journal, Alcoholism: Clinical and Experimental Research (ACER) from 2010 to 2020, with the goal of sharing the results with the alcohol research community to enhance awareness.

METHODS

The search for stigmatizing language in ACER was limited to NIH-funded articles made publicly available on PubMed Central (PMC). Though ACER is not an open-access journal, original research and reviews directly funded by NIH are published to PMC for open access to the public as required by the conditions of NIH funding. ACER articles published on PMC were searched from 2010 to 2020 with specific queries for individual terms of interest including those considered pejorative ("alcoholic," "addict," and "abuser") and outdated ("alcohol dependent," "alcohol abuse," and "alcoholism"). The number of articles containing a term of interest for a given year was divided by the total number of articles published in that year to determine the percent use of each term per year.

RESULTS

Our search of research and reviews (n = 1903) published in ACER on PMC determined that although the use of pejorative and outdated terminology has decreased over time, there is continued use of the term "alcoholic" over the last decade. Specifically, in 2020, over 40% of articles searched for in PMC still included "alcoholic." The results of a separate manual search (n = 110) on the Wiley Online Database showed that approximately 30% of articles used the term "alcoholic" in a stigmatizing manner.

CONCLUSIONS

Stigmatizing language can perpetuate negative biases against people with alcohol use disorder. We encourage researchers to shift away from language that maintains discriminatory conceptions of alcohol use disorder. Reducing stigma has the potential to increase rates of treatment seeking and improve treatment outcomes for individuals with alcohol use disorder.

Barriers to Accessing Addiction Treatment for Women at Risk of Homelessness

Women remain under-represented in addiction treatment, comprising less than a third of clients in treatment services. Shame, stigma, and fear of legal and social repercussions (e.g., child protection involvement) are major barriers impacting on treatment-seeking for women. This is compounded for women at risk of homelessness, with practical and logistical reasons for not engaging in treatment. We conducted a qualitative study with both clinicians and service-providers, and women with lived experience of addiction and at risk of homelessness, to identify barriers to access and help-seeking within this vulnerable population. Adult women with lived experience of homelessness and addiction were invited to participate in an online focus group. Interviews were transcribed and analyzed using framework analysis. Analysis resulted in the identification of barriers to access in three areas. These were system-related, socio-cultural, and emotional barriers. We also present findings from the focus group recorded in real-time, using the novel method of digital illustration. This study highlights key factors impacting on help-seeking and access to treatment for addiction faced by women at risk of homelessness. The findings of this study highlight important areas of consideration for clinicians and service-providers working with women who experience addiction, as well as informing future research directions for this priority population. Findings are discussed in the context of exigent literature.

Gender, Addiction, and Removal of Children Into Care

INTRODUCTION

Parental addiction can result in harm to children and removal of children by the Local Authority. Less is known about the impact of removal of children on their parents and whether gender has a role in this process.

METHODS

Data on 736 service users were obtained from the caseloads of 8 nurses and 12 social care workers from an Alcohol and Drug Recovery Service in Scotland. Gender differences in prevalence/patterns of child removal, associations between child removal and parental factors and the relationship between removal and suicidality were examined.

RESULTS

Mothers were more likely to have had one or more children removed compared to fathers (56.6 vs. 17.7%; p < 0.001) and were more likely to have a series of individual child removals (22.5 vs. 4.3%; p = 0.014). In addition to female gender, younger age, drug use, mental health and suicide attempts were also associated with child removal. Mothers who had children removed and women who were not mothers were more likely to have made an attempt to end their lives than women who had children but had not had them removed.

CONCLUSION

Gender differences were apparent in prevalence and patterns of child removal. Mothers were six times more likely to have children removed compared to fathers. Child removal occurred alongside other risk factors suggesting that families need holistic support for their multiple areas of need. Services should be aware of the link between child removal and suicide and provide additional support to mothers during and after removal.

Polysubstance use classes and health outcomes among women attending specialist substance use treatment services

INTRODUCTION

Substance use is increasingly prevalent among women. Little research examines subgroups of women with substance use issues to identify their characteristics and thus enable treatment recommendations. The present study used latent class analysis to identify subgroups of substance use among women in substance-use treatment based on use in the 30 days prior to intake and examined changes in mental health and treatment outcomes following 60 days of treatment.

METHODS

Participants were women (N = 493) attending specialist non-government substance use treatment services in New South Wales, Australia.

RESULTS

Four distinct classes of substance users were identified: (i) Amphetamine Type Stimulants (ATS) Polysubstance (40.6%, n = 200); (ii) Alcohol Only (33.1%, n = 163); (iii) Cannabis and Alcohol (17.0%, n = 84) and (iv) Other Polysubstance (9.3%, n = 46). Women in the ATS Polysubstance class were the youngest and those in the Alcohol Only class were the oldest.

DISCUSSION AND CONCLUSIONS

Findings show that classes with high polysubstance use (ATS Polysubstance) differed from the single-substance use class (Alcohol Only). The ATS Polysubstance class had significantly greater improvements in health outcomes after 60 days compared to the Alcohol Only class. These findings suggest that although women with polysubstance use can benefit from substance use treatment, younger women (ATS Polysubstance) may benefit even more than older women (Alcohol Only). Future research should utilise a longitudinal design and examine additional psychosocial characteristics to extend on current findings.

The impact of PSTD on service access among people who use drugs in Vancouver, Canada

BACKGROUND

Settings throughout the United States and Canada are contending with high rates of drug-related overdose. This in turn has prompted efforts to more effectively engage people who use drugs (PWUD) in treatment and care. However, while co-morbid mental disorders are prevalent among PWUD and can undermine access to services, the impact of post-traumatic stress disorder (PTSD) on service access is not known. Therefore, we sought to assess whether PTSD is associated with difficulties accessing health and social services among PWUD in Vancouver, Canada.

METHODS

Survey data was derived from two prospective cohorts of PWUD in Vancouver, Canada for the period of April 2017 to November 2018. PTSD was assessed using the PTSD Checklist for the DSM-V (PCL-5). Generalized estimating equations (GEE) was used to estimate the relationship between PTSD and self-reported inability to access health and social services, after adjustment for confounders.

RESULTS

Among 810 participants included in our analysis, 316 (39.0%) participants qualified for a provisional PSTD diagnosis, and 117 (14.4%) reported difficulties accessing services. In a multivariable GEE analysis, a PTSD diagnosis (adjusted odds ratio = 1.69, 95% confidence interval: 1.12-2.55) was independently associated with difficulties accessing services.

CONCLUSIONS

We found high rates of PTSD and self-reported difficulties accessing services among PWUD in Vancouver, as well as a positive association between PTSD and difficulties with service access. These findings highlight the need for trauma-informed approaches to service delivery for PWUD, as well as enhanced provider training specific to PTSD.
