Co-occurring Substance Abuse and Mental Health Problems among Homeless Persons: Suggestions for Research and Practice

Multicomponent Co-Occurring Disorders Treatment and Wraparound Services for Individuals Experiencing Chronic Homelessness

Individuals experiencing chronic homelessness have high rates of persistent co-occurring mental health and substance use disorders (COD), and they often have difficulty with service engagement and retention, resulting in symptom exacerbation and housing loss. This study pilot tested Maintaining Independence and Sobriety Through Systems Integration, Outreach and Networking (MISSION), a multicomponent wraparound treatment approach to improve COD symptoms and housing stability among individuals experiencing chronic homelessness and persistent COD. This open pilot study enrolled and assessed 109 individuals with a COD experiencing chronic homelessness and offered one year of MISSION. Statistically significant improvements were observed in behavioral health symptoms and functioning, days of illicit drug use, and housing stability. By treatment completion, 85% of participants were referred to social and behavioral supports. This pilot study demonstrates that MISSION helped to successfully engage participants in treatment, reduce substance use and mental health symptoms, and improve housing outcomes.

Examining a Triple Threat: The Intersection of Mental Health, Substance Use, and Re-entry of a Sample of Justice-Involved Persons

Having a mental health (MH) or substance use (SU) issue can make the transition from prison to the community a challenging process. Despite this, few studies have quantified how justice-involved individuals with mental health issues only, substance use only, those with both struggles, and those with neither are uniquely affected. Using a sample of re-entering men who were released from twelve state prisons in the United States, we assessed the effects of having MH and SU issues on their drug use during re-entry. Furthermore, we examined their differing coping reactions to housing insecurity, joblessness, and family tension after release. The results demonstrated that respondents' risk of SU during re-entry was associated with MH and SU issues measured at release. Those with co-occurring MH and SU challenges were at the highest risk of SU during re-entry. Furthermore, challenging life situations during re-entry exerted an amplified effect on SU for respondents with both anxiety and SU issues. The findings suggest that post-incarcerated individuals with co-occurring MH and SU issues have the highest risk of SU, and their reaction to re-entry barriers is distinct from their peers. Quality services to address co-occurring MH and SU may be needed to facilitate a smooth transition from prison to the community.

Association between psychosocial factors and co-morbid cigarette smoking and alcohol use in a population experiencing homelessness

The prevalence of combustible cigarette smoking in populations experiencing homelessness in the United States is five times that of the general population. The psychosocial well-being of persons who smoke and experience homelessness is poorer if such persons also use alcohol heavily. The PTQ2 study was a randomized clinical trial among persons experiencing homelessness who were also current smokers and heavy alcohol consumers. Secondary data analysis of the PTQ2 baseline data was conducted to examine associations among psychosocial variables (anxiety, depression, hopelessness, social network size), heaviness of smoking (cigarettes/day) and alcohol consumption (drinking days/month), and duration and frequency of homelessness. Among the 420 participants, the majority were male (75%), black (70%) and non-Hispanic (94%) with a mean age of 46.6 years (SD = 11.6).  Bivariate analyses show that heaviness of smoking was positively correlated with social network size (r = 0.16, p = .001). Heaviness of drinking was positively correlated with the MINI anxiety score (r = 0.13, p = .009) and marijuana use (median total number of drinks in past 30 days among those who used marijuana in past 30 days vs. did not use: 50 vs. 24, p < .0001), and associated with frequency of homelessness (median total number of drinks in past 30 days among those experiencing homelessness once vs. >1 time: 30 vs. 44, p = .022). The findings highlight the psychosocial factors that warrant consideration when addressing heavy smoking and alcohol consumption in persons experiencing homelessness.

Backgrounds and perspectives of San Antonio street sleepers

Background

The question of what brings someone to homelessness and keeps them there has many varied and complex answers. The authors believe the answers lie within the persons experiencing homelessness (PEH).

Methods

This is an interpretive approach study based on convenience sampling of the San Antonio, TX, unsheltered population, utilizing semi-structured interviews from January 2022 through November 2022.

Results

The six most common themes that emerged from the subjects' backgrounds were 1) jail or prison time or other personally significant legal issues; 2) personal substance abuse or addiction struggles; 3) physical and mental health challenges as an adult; 4) disdain of shelters and preference for rough sleeping; 5) a problematic childhood; 6) did not enjoy school as a child or young adult.

Conclusion

To gain more insight into a situation as complex as the state of homelessness, researchers should meet with those on the frontline of this epidemic and hear first-hand their personal histories, challenges, successes, and suggestions. Though not a novel approach, the researchers found limited previous literature in regard to approach, scope and in relation of causation related to homelessness, especially about the U.S. unsheltered population. The ultimate goal is for such research to help guide outreach services and legislation related to PEH.

Trauma Experience Among Women Who Have Substance Use Disorders and are Homeless or Near Homeless

Women with substance use disorders (SUDs) who are homeless or near homeless have high rates of mental health, behavioral health, and SUD treatment needs. To effectively respond to these needs, it is critical to understand the population-specific trauma experiences of these women. This descriptive study examined the extent and nature of trauma experience among women who have an SUD and are homeless or near homeless. Results (n = 851 women) indicated high rates of trauma experience. All participants (100%) reported at least one type of trauma experience in their lifetime, with the majority (75.3%) having experienced five to seven of the seven types of trauma experiences assessed. Participants reported high levels of emotional severity related to the majority of traumatic events experienced. The pervasiveness of the trauma experiences and the related emotional impact among women with SUDs who are homeless or near homeless reinforce the necessity for trauma-informed care in treatment settings.

A Research-Informed Approach to Providing Behavioral Healthcare to Women with Extensive Trauma Histories

Translating research to behavioral healthcare practice is vital for improving treatment impact but can be challenging. Current and lifetime histories of trauma need to be considered in behavioral healthcare provision as they can significantly affect an individual's treatment experience. This article provides guidance on how to utilize research findings regarding trauma prevalence and experiences of women who have substance use disorder and who are homeless or near homeless to help guide responsive healthcare and treatment in practice.

The Relationship Between Serious Mental Illness and Criminal Offending in Persons Experiencing Homelessness: The Role of Substance Use Disorder

Individuals who live with mental illness are encumbered by related risk factors that increase the probability of legal involvement. The goal was to determine how homelessness and substance use disorder are intervening factors in the relationship between symptoms of serious mental illness (SMI) and criminal offending. A sample of 210 chronically homeless adults receiving SAMHSA-funded outreach and psychiatric rehabilitation services between 2014 and 2016 was recruited in a study of interventions to address housing in homeless persons with a SMI. Participants were interviewed and data collected were analyzed using structural equation modeling. Statistical analysis showed that homelessness severity mediated the relationship between SMI symptom severity and criminal offenses committed in the past 30 days in participants with a substance use disorder but not in those with no substance use diagnosis. Results show that homelessness and substance use are important to address to possibly alter trajectories for criminal justice involvement.

Housing Instability Associated with Return to Stimulant Use among Previously Abstaining Women

Stimulant use among unstably housed individuals is associated with increased risks of psychiatric co-morbidity, violence, HIV transmission, and overdose. Due to a lack of highly effective treatments, evidence-based policies targeting the prevention of stimulant use disorder are of critical importance. However, little empirical evidence exists on risks associated with initiating or returning to stimulant use among at-risk populations. In a longitudinal cohort of unstably housed women in San Francisco (2016-2019), self-reported data on stimulant use, housing status, and mental health were collected monthly for up to 6 months, and factors associated with initiating stimulants after a period of non-use were identified through logistic regression. Among 245 participants, 42 (17.1%) started using cocaine and 46 (18.8%) started using methamphetamine. In analyses adjusting for demographics and socio-structural exposures over the preceding month, experiencing street homelessness was associated with initiating cocaine use (AOR: 2.10; 95% CI: 1.04, 4.25) and sheltered homelessness with initiating methamphetamine use (AOR: 2.57; 95% CI: 1.37, 4.79). Other factors-including race, income, unmet subsistence needs, mental health, and treatment adherence-did not reach levels of significance, suggesting the paramount importance of policies directed toward improving access to permanent supportive housing to prevent stimulant use among unstably housed women.

Re-Purposing FDA-Approved Drugs for Opioid Use Disorder

OBJECTIVE

To investigate FDA-approved drugs prescribed for unrelated diseases or conditions that promote remission in subjects diagnosed with opioid use disorder (OUD).

METHODS

This was a retrospective observational study utilizing the TriNetX electronic medical record data. Subjects between 18 and 65 years old were included in this study. First, a drug screen was employed to identify medications used for chronic illness that are associated with OUD remission. Based on Fisher's exact test for significance, 28 of 101 medications were selected for further analysis. Positive (buprenorphine/methadone) and negative controls (benazepril) were included in the analysis. Medications were analyzed in the absence and presence of buprenorphine or methadone, two medications used to treat OUD, to identify the likelihood of OUD remission up to one year following the index event.

RESULTS

We identify 8 medications (prazosin, propranolol, lithium carbonate, olanzapine, quetiapine, bupropion, citalopram, and escitalopram) that may be useful for increasing remission in OUD in the absence of buprenorphine or methadone. Additionally, our results identify psychiatric medications that when taken alongside buprenorphine and methadone improve remission rates.

CONCLUSION

These results provide medication options that may be useful in treating OUD as well as integrated therapies to treat comorbid mental illness.

Re-incarceration and associated social, structural and behavioural factors among people who use drugs in an urban Canadian setting

BACKGROUND

People who use drugs (PWUD) are disproportionately incarcerated, however little is known about specific substance use, social and structural factors associated with re-incarceration among PWUD. We aimed to identify the socio-structural and substance use factors associated with re-incarceration among structurally-marginalized PWUD.

METHODS

We used longitudinal data from two prospective cohorts of PWUD in Vancouver, Canada. We included adults reporting at least one incarceration event in the last six months and who completed at least one additional follow-up study visit. We performed multivariable extended Cox regression to explore factors associated with re-incarceration.

RESULTS

Among 468 eligible participants, the median age was 40 years (Q1-Q3 = 34-46 years), 346 (73.9%) were men, 177 (37.8%) identified as Indigenous, and 227 (48.5%) experienced at least one re-incarceration event. Incidence rate of re-incarceration was 157 incarceration events per 1000 person years. In multivariable analyses, homelessness (adjusted hazard ratio [AHR] = 2.17; 95% confidence interval [95% CI]: 1.79-2.61), community judicial supervision (AHR = 3.89; 95% CI: 3.21-4.71) and re-incarceration during the study period (once: AHR = 1.95, 95% CI: 1.55-2.44; two or more events: AHR = 1.53, 95% CI: 1.23-1.90) were positively associated with re-incarceration. Among substance use variables that included illicit drugs, only heavy alcohol use remained significantly associated with re-incarceration across analyses after adjustment (AHR = 1.32; 95% CI: 1.06-1.65). Engagement in addiction treatment (AHR = 0.63; 95% CI: 0.53-0.75), mental illness (AHR = 0.70; 95% CI: 0.59-0.84) and age (AHR = 0.96; 95% CI: 0.95-0.97) were negatively associated with re-incarceration.

CONCLUSION

Access to housing and substance use services, including treatment for alcohol use disorder, following incarceration may reduce re-incarceration among PWUD. The high rates of re-incarceration of PWUD in our sample underscores how structural factors-such as homelessness and criminalization of substance use-drive re-incarceration among PWUD.

The role of community pharmacies in the HIV and HCV care continuum

Introduction

In 2019, there were over 1.1 million people living with human immunodeficiency virus (HIV) and 2.4 million people living with hepatitis C virus (HCV) in the United States. One in seven (14%) are unaware of their HIV infection and almost half of all HCV infections are undiagnosed. People with unstable housing are disproportionately affected by HIV and HCV. The present study will evaluate interventions by community pharmacists that may reduce HIV and HCV transmission and promote linkage to care.

Methods

This study was conducted in an independent community pharmacy in Spokane, Washington. Eligible study participants were walk-in patients of the pharmacy, over the age of 18, and experiencing homelessness. Pharmacy patients were excluded if they had a history of HIV or HCV diagnosis, received a screening for HIV or HCV in the last six months or were unable to give informed consent. The intervention included administration of HIV and HCV point-of-care testing (POCT) using a blood sample, risk determination interview, comprehensive HIV and HCV education, and personalized post-test and risk mitigation counseling followed by referral to partnering health clinics.

Results

Fifty participants were included in the final data analysis. Twenty-two participants (44%) had a reactive HCV POCT, and one participant had a reactive HIV POCT. Of the 94% of participants who reported illicit drug use, 74% reported injection drug use. Seventy-six percent (n = 38) qualified for PrEP. Pharmacist referrals were made for 28 participants and 71% were confirmed to have established care.

Conclusion

Individuals experiencing homelessness are at an increased risk for acquiring HIV and HCV due to risky sexual behaviors and substance misuse. PrEP is underutilized in the U.S. and pharmacist involvement in the HIV and HCV care continuum may have a significant impact in improving linkage and retention in care of difficult to treat populations.

Experience delivering an integrated service model to people with criminal justice system involvement and housing insecurity

BACKGROUND

People returning to communities from prison or jail face stressors related to securing housing, including discrimination, restrictions based on prior felony convictions, and limited economic and social resources. Existing housing programs can effectively reduce housing instability but often do not fully address the needs of people involved in the criminal justice system experiencing homelessness who often have co-occurring chronic medical issues, and psychiatric and substance use disorders.

METHODS

Project CHANGE is an ongoing program to deliver person-centered, integrated care and services to individuals involved with the criminal justice system and experiencing homelessness. Applying a Screening, Brief Intervention, (Referral to) Treatment framework, a comprehensive needs assessment is followed by delivery of intensive housing and vocational case management; and psychiatric, substance use, and medical services in a single location by an interdisciplinary team. Participants are followed with study interviews for 12 months. The current analysis was designed to assess the baseline characteristics and needs of the sample population, and the intensity of contact required for integrated service delivery.

RESULTS

Between November 2019 and September 2021, 86 participants were enrolled, of whom 64% had been released from prison/jail in the past 6 months; the remainder were on parole, probation, or intensive pretrial supervision. Participants were unstably housed (64%) or residing outdoors (26.7%) or in a shelter (24.4%). Most participants had high medical need and frequent healthcare engagement through outpatient and emergency department visits. Most participants were at-risk for clinical depression, and half were diagnosed with anxiety, dissociative, stress-related, somatoform, and other non-psychotic psychiatric disorders. Over 12-month follow-up, the interdisciplinary team made over 500 contact encounters, over half of which resulted in direct services provided, including obtaining vital documents for homelessness verification, housing applications, and employment coaching.

CONCLUSION

Navigation of services can be particularly challenging for individuals experiencing criminal justice involvement, homelessness, and co-occurring medical, psychiatric, and substance use issues, which can be addressed holistically in an integrated service model. Integrated service delivery was time-, resource-, and staffing-intensive, and challenged by the COVID-19 pandemic, requiring innovative solutions to sustain participant engagement.

Scoping review of managed alcohol programs

BACKGROUND

Internationally, strategies focusing on reducing alcohol-related harms in homeless populations with severe alcohol use disorder (AUD) continue to gain acceptance, especially when conventional modalities focused on alcohol abstinence have been unsuccessful. One such strategy is the managed alcohol program (MAP), an alcohol harm reduction program managing consumption by providing eligible individuals with regular doses of alcohol as a part of a structured program, and often providing resources such as housing and other social services. Evidence to the role of MAPs for individuals with AUD, including how MAPs are developed and implemented, is growing. Yet there has been limited collective review of literature findings.

METHODS

We conducted a scoping review to answer, "What is being evaluated in studies of MAPs? What factors are associated with a successful MAP, from the perspective of client outcomes? What are the factors perceived as making them a good fit for clients and for communities?" We first conducted a systematic search in PubMed, Embase, PsycINFO, CINAHL, Sociological Abstracts, Social Services Abstracts, and Google Scholar. Next, we searched the gray literature (through focused Google and Ecosia searches) and references of included articles to identify additional studies. We also contacted experts to ensure relevant studies were not missed. All articles were independently screened and extracted.

RESULTS

We included 32 studies with four categories of findings related to: (1) client outcomes resulting from MAP participation, (2) client experience within a MAP; (3) feasibility and fit considerations in MAP development within a community; and (4) recommendations for implementation and evaluation. There were 38 established MAPs found, of which 9 were featured in the literature. The majority were located in Canada; additional research works out of Australia, Poland, the USA, and the UK evaluate potential feasibility and fit of a MAP.

CONCLUSIONS

The growing literature showcases several outcomes of interest, with increasing efforts aimed at systematic measures by which to determine the effectiveness and potential risks of MAP. Based on a harm reduction approach, MAPs offer a promising, targeted intervention for individuals with severe AUD and experiencing homelessness. Research designs that allow for longitudinal follow-up and evaluation of health- and housing-sensitive outcomes are recommended.

Homelessness and health-related outcomes: an umbrella review of observational studies and randomized controlled trials

BACKGROUND

Homelessness has been associated with multiple detrimental health outcomes across observational studies. However, relatively few randomized controlled trials (RCTs) have been conducted on people who experience homelessness (PEH). Thus, this umbrella review ranked the credibility of evidence derived from systematic reviews (SRs) and meta-analyses (MAs) of observational studies investigating the associations between homelessness and any health outcome as well as RCTs targeting health needs in this population.

METHODS

Several databases were systematically searched from inception through April 28, 2021. Any SR and/or MA reporting quantitative data and providing a control group were eligible for inclusion. The credibility of the evidence derived from observational studies was appraised by considering the significance level of the association and the largest study, the degree of heterogeneity, the presence of small-study effects as well as excess significance bias. The credibility of evidence was then ranked in five classes. For SRs and/or MAs of RCTs, we considered the level of significance and whether the prediction interval crossed the null. The AMSTAR-2 and AMSTAR-plus instruments were adopted to further assess the methodological quality of SRs and/or MAs. The Newcastle-Ottawa Scale (NOS) was employed to further appraise the methodological quality of prospective cohort studies only; a sensitivity analysis limited to higher quality studies was conducted.

RESULTS

Out of 1549 references, 8 MAs and 2 SRs were included. Among those considering observational studies, 23 unique associations were appraised. Twelve of them were statistically significant at the p≤0.005 level. Included cases had worst health-related outcomes than controls, but only two associations reached a priori-defined criteria for convincing (class I) evidence namely hospitalization due to any cause among PEH diagnosed with HIV infection, and the occurrence of falls within the past year among PEH. According to the AMSTAR-2 instrument, the methodological quality of all included SRs and/or MAs was "critically low." Interventional studies were scant.

CONCLUSION

While homelessness has been repeatedly associated with detrimental health outcomes, only two associations met the criteria for convincing evidence. Furthermore, few RCTs were appraised by SRs and/or MAs. Our umbrella review also highlights the need to standardize definitions of homelessness to be incorporated by forthcoming studies to improve the external validity of the findings in this vulnerable population.

Examining Recovery Status Trends over 7-Years for Men and Women Clients of a Substance Use Disorder Recovery Housing Program

Adults who are homeless and/or involved in the criminal justice system have significantly higher risks of substance use disorders (SUD)s and they may have increased difficulty initiating and maintaining traditional SUD treatments. To address the needs of adults with SUDs who are homeless/criminal justice system involved the Recovery Kentucky programs were established. This study examined outcomes for this recovery housing program among an unduplicated statewide sample of men ( n=672) and women ( n = 732) clients who entered the Recovery Kentucky program and who were followed-up about 12 months after program entry across a 7-year period. Low, but similar rates of problem alcohol or illicit drug use at follow-up were found across the 7-year period. Men had higher rates of return to use than women. Further, about 40% of the clients had at least one recovery status vulnerability factor at follow-up each year of the study with no differences by gender.

Homelessness and polysubstance use: A qualitative study on recovery and treatment access solutions around an urban library in Southern California, USA

People experiencing homelessness face many obstacles and barriers when it comes to getting help for their substance use. Recently, there has been an increase in substance use and opioid overdoses at public libraries, which are easily accessible public places for those struggling with homelessness. We aimed to understand this population's experience with recovery. This has led to an exploration of the intersection of experiencing homelessness and substance use-related problems and its impact on barriers for recovery, along with facilitators to treatment and recovery. From January to June 2019, researchers interviewed 22 library patrons experiencing homelessness and actively using substances at a Southern Californian library in a major metropolitan area. Data were coded and analysed using a thematic analysis. Researchers independently coded text files for data analysis and discussed codes until consensus was reached. Library patrons who reported substance use were a mean age of 39 (range: 22-63); over half were white people (59%) and male (59%); 77% reported currently sleeping on the street; 18% lived in shelters. Themes for barriers to recovery were experiencing withdrawal, access to resources and coping with being homeless. Themes related to facilitators to treatment and recovery were Narcan access and overdose education, connectedness and trauma recovery. People experiencing homelessness are hard to reach and those using substances pose even more vulnerabilities. Many patrons attribute their circumstances to their substance use and disconnectedness to resources and supports to quit. Further research is needed on best practices for multidisciplinary care coordination for this population.

Examining Recovery Status and Supports before and after Substance Abuse Disorder Treatment Among Clients Who Experienced Lifetime and Recent Firearm-Related Threats

Firearm-related risks have often been overlooked in the sequela of substance use and substance use disorders. This study compares adult substance abuse disorder treatment (SADT) clients who experienced recent ( n = 274) and lifetime ( n = 889) firearm threats to adults who were not threatened with a firearm ( n = 2029) before and 12 months after program entry. More men experienced firearm threats (38.8%) than women (34.2%). However, among those with any firearm threats, more women (27.2%) experienced firearm threats in the year before program entry than men (20.2%). Being threatened with a firearm was associated with increased economic vulnerability, criminal justice system involvement, mental health problems, and victimization both before and after SADT program entry. A higher number of adverse childhood experiences were associated with firearm threats and particularly recent firearm threats. Results of this study underscore the importance of screening for firearm-related risks in substance abuse disorder treatment programs.

Factors associated with current substance use among a sample of homeless individuals in Cape Town, South Africa: a secondary data analysis

Homelessness is a global issue that is often associated with substance use. Research on this relationship in low- to middle-income countries (LMIC) is limited. We aimed to explore which factors are associated with substance use through secondary data analysis of a sample of 472 adults who attended services for homeless individuals in Cape Town, South Africa. Logistic regression was utilized to investigate if length of homelessness was associated with current alcohol and drug use respectively, after accounting for other factors. Current drug use (44.9%) was higher than current alcohol use (22.7%) and the most prevalent lifetime drug was methamphetamine (32.6%). After adjusting for lifetime substance use, and source of income, length of homelessness was not significantly associated with current alcohol use (less than on year: OR = 2.60; 95% CI: 0.78-8.66; one or more years: OR = 0.90; 95% CI: 0.32-2.57) or current drug use (less than one year: OR = 0.78; 95% CI: 0.41-1.47; one year or more: OR = 1.04; 95% CI: 0.56-1.93). These results highlight the need to further investigate other factors that may influence current alcohol or drug use among populations at risk of being homeless, and to utilize validated measures of substance and other mental health conditions.

Associations of housing stress with later substance use outcomes: A systematic review

A synthesis of existing evidence regarding the association of housing stress with later substance use outcomes can help support and inform housing interventions as a potential strategy to address problematic substance use. We conducted a comprehensive search of PubMed, Web of Science, PsycInfo, CINAHL, Social Work Abstracts, and Sociological Abstracts and systematically screened for articles examining housing stress and later substance use outcomes among U.S. adults. Across 38 relevant articles published from 1991 to 2020, results demonstrated an association of homelessness with an increased likelihood of substance use, substance use disorders (SUD), and overdose death. Results regarding the association of homelessness with receipt and completion of SUD treatment were mixed, and one study indicated no association of homelessness with motivation to change substance use behaviors. Several studies did not find an association of unstable housing with substance use or receipt of SUD treatment, while others found an association of unstable housing with intensified SUD symptoms and a decreased likelihood of completing SUD treatment. Overall, while there is evidence of an association of homelessness with later substance use, SUD, and overdose death, results for other forms of housing stress and some substance use outcomes are less consistent. There are several methodological considerations specific to selected measures of housing stress and substance use, study populations, and analytic approaches that have implications for results and directions for future research. Despite these considerations, results collectively suggest that innovative interventions to address housing stress, namely homelessness, may help mitigate some substance use outcomes.

Barriers for homeless with dual diagnosis: lessons learned from intensive mobile psychosocial assertive community treatment program

Purpose

Dual diagnosis is a term that describes the co-occurrence of mental health disorders or illness and substance use or abuse disorders. Because this co-occurrence results in multiple diseases, layers of treatment are often needed to successfully create positive change in the individual. The purpose of this study is to explore factors of treatment that could facilitate improvements in functionality and quality of life for those with a dual diagnosis.

Design/methodology/approach

A secondary data analysis, using both quantitative and qualitative data, was completed. Secondary analysis is an empirical exercise that applies the same basic research principles as studies using primary data and has steps to be followed, including the evaluative and procedural steps commonly associated with secondary data analysis. Documentation data from the intensive mobile psychosocial assertive community treatment program was gathered for this analysis; this program was used because of the intensive and community-based services provided to patients with a dual diagnosis.

Findings

The major findings from this secondary analysis suggested that significant barriers included “denial” (e.g. evasion, suspension or avoidance of internal awareness) of diagnoses, complicated treatment and other barriers related to housing. Ultimately, these findings provided greater insight into potential effective treatment interventions for people living with a dual diagnosis.

Originality/value

This study adds to the growing body of literature showing that patient-centered care allows for more effective treatment and ultimately, improved health outcomes.

Positive effects of community attachment on internalised stigma and wellbeing among people who inject drugs

BACKGROUND

Internalised stigma experienced by people who inject drugs (PWID) is known to have negative health consequences. Research has explored factors that may protect or buffer individuals from the negative consequences of internalised stigma. Community attachment, or perceived connection to a community of like people, can have numerous health-related benefits. However, this relationship may be complex for PWID; being part of a social network of PWID may provide opportunity for more frequent drug use and equipment sharing. This study investigated the relationships between community attachment, internalised stigma, and wellbeing among PWID, while also addressing potential health risks associated with PWID community attachment.

METHODS

PWID (n=603) were recruited through nine peer-based drug user organisations across Australia with assistance from the peak consumer organisation. Participants completed a survey measuring community attachment, internalised stigma, personal wellbeing, injecting frequency, and equipment sharing.

RESULTS

Greater attachment to a PWID community was associated with lower internalised stigma, but also with sharing of injecting equipment and increased frequency of injecting behaviour. The relationship between community attachment and personal wellbeing was mediated by internalised stigma, however this was only the case for PWID who reported no sharing of injecting equipment.

CONCLUSIONS

This research highlights the significance of community attachment for PWID while also noting the complexity of this relationship and the potential negative consequences. It is important to view networks of PWID communities as sources of positive social capital, where norms about health behaviours and harm reduction can be promoted and which can buffer community members from the harms associated with stigma.

Scope, quality and inclusivity of international clinical guidelines on mental health and substance abuse in relation to dual diagnosis, social and community outcomes: a systematic review

OBJECTIVE

It is estimated that up to 75% of patients with severe mental illness (SMI) also have substance use disorder (SUD). The aim of this systematic review was to explore the scope, quality and inclusivity of international clinical guidelines on mental health and/or substance abuse in relation to diagnosis and treatment of co-existing disorders and considerations for wider social and contextual factors in treatment recommendations.

METHOD

A protocol (PROSPERO CRD42020187094) driven systematic review was conducted. A systematic search was undertaken using six databases including MEDLINE, Cochrane Library, EMBASE, PsychInfo from 2010 till June 2020; and webpages of guideline bodies and professional societies. Guideline quality was assessed based on 'Appraisal of Guidelines for Research & Evaluation II' (AGREE II) tool. Data was extracted using a pre-piloted structured data extraction form and synthesized narratively. Reporting was based on PRISMA guideline.

RESULT

A total of 12,644 records were identified. Of these, 21 guidelines were included in this review. Three of the included guidelines were related to coexisting disorders, 11 related to SMI, and 7 guidelines were related to SUD. Seven (out of 18) single disorder guidelines did not adequately recommend the importance of diagnosis or treatment of concurrent disorders despite their high co-prevalence. The majority of the guidelines (n = 15) lacked recommendations for medicines optimisation in accordance with concurrent disorders (SMI or SUD) such as in the context of drug interactions. Social cause and consequence of dual diagnosis such as homelessness and safeguarding and associated referral pathways were sparsely mentioned.

CONCLUSION

Despite very high co-prevalence, clinical guidelines for SUD or SMI tend to have limited considerations for coexisting disorders in diagnosis, treatment and management. There is a need to improve the scope, quality and inclusivity of guidelines to offer person-centred and integrated care.

Algorithm-Driven Substance Use Disorder Treatment for Inner-City Clients With Serious Mental Illness and Multiple Impairments

ABSTRACT

Mental health clients with serious mental illness in urban settings experience multiple chronic stresses related to poverty, unemployment, discrimination, homelessness, incarceration, hospitalization, posttraumatic stress disorder, pain syndromes, traumatic brain injury, and other problems. Substance use disorder exacerbates these difficulties. This study examined the efficacy of algorithm-driven substance use disorder treatments for 305 inner-city mental health clients with multiple challenges. Researchers assessed substance use quarterly using a combination of standardized self-reports and case manager ratings. Of the 305 multiply impaired clients who began treatment, 200 (66%) completed 2 years of treatment. One fourth (n = 53) of the completers were responders who developed abstinence and improved community function; one half (n = 97) were partial responders, who reduced substance use but did not become abstinent; and one fourth (n = 50) were nonresponders. Evidence-based interventions for substance use disorder can be effective for multiply impaired, inner-city clients, but numerous complications may hinder recovery.

Psychometric Properties of the Recovery Home Environment Scale

BACKGROUND

Recovery homes for persons with alcohol and drug problems provide an abstinent living environment and social support for recovery. Research shows residents in these homes make significant, sustained improvements. However, descriptions of recovery environments within the homes have been limited.

PURPOSE

The current study assessed psychometric properties for the Recovery Home Environment Scale (RHES), which assessed social environments within one type of recovery home, sober living houses (SLHs).

METHODS

373 residents were interviewed at entry into the house, 1-month follow-up, and 6-month follow-up. Measures included the RHES, other measures of the social environment, days of substance use, and length of stay.

RESULTS

Principal components analysis suggested the RHES was largely unidimensional. Exploratory factor analysis suggested items could be grouped into recovery support (3 items) and recovery skills (5 items). Cronbach's alphas for the full scale and the recovery support and recovery skills subscales were 0.91, 0.89, and 0.87, respectively. As hypothesized, construct validity of the RHES was supported by correlations with other measures of the social environment and predictive validity was supported by associations with length of stay and substance use.

CONCLUSIONS

SLHs have been described as "the setting is the service." However, the field has lacked a way to capture characteristics of the social environment. The RHES represents a new way to measure the recovery environment by focusing on social interactions among residents within SLHs and shared activities in the community.

Individuals experiencing chronic homelessness: A 10-year follow-up of a cohort in Spain

With the start of the great economic recession in 2007, homelessness increased fivefold in some regions of southern Europe. Larger numbers of people experiencing homelessness, compounded by a lowered capacity for social and health services to respond to their needs, precipitated an increase in so-called 'chronic homelessness'. The aim of this study was to establish the presence of chronic homelessness in a defined geographical area of Spain, and to determine the prevalence of diagnosed mental disorders within both the chronic and non-chronic homeless population. A prospective and descriptive study was designed to monitor a cohort of 826 individuals experiencing homelessness who constituted the entire identified homeless population in the relevant territory in 2006. This sample was followed until 2016 and sociodemographic as well as clinical information was collected, including the time spent homeless. The results obtained indicated that one in 10 participants met the criteria for chronic homelessness, a rate that is lower than in the US, where the definition of chronicity that was applied originates from. Alcohol use disorder was the most common mental health disorder that contributed to the chronicity associated with homelessness. Being born in the country (Spain) where the study was conducted and being older were the main other variables associated with chronicity. People defined as chronically homeless in Spain were on average younger than in the US, but women were present in the chronic subgroup at a similar rate. We also reflect on the limitations of the study and in particular the appropriateness of the concept of chronicity as applied to homelessness.

"I Felt Safe": The Role of the Rapid Rehousing Program in Supporting the Security of Families Experiencing Homelessness in Salt Lake County, Utah

Homelessness is a public health issue that many organizations are addressing through a Housing First Model. One such organization is The Road Home (TRH), which provides services to homeless individuals and families in Salt Lake County. TRH is perhaps best known for their emergency shelters, but the organization also administers the Rapid Rehousing Program (RRHP), designed to help families experiencing homelessness transition back into stable housing. Those experiencing homelessness tend to have high rates of chronic mental/physical disabilities as well as issues related to substance abuse. Having a home is the first step toward achieving some kind of stability in their lives. The RRHP allows families to find housing in the private rental market and will cover the initial costs and several months of rent for clients. While the program has been praised by policymakers and social service providers for helping homeless families find rental housing, there is no empirical research about participant perspectives regarding their residential (in)security. The research question of this article is: what is the role of the RRHP in supporting the security of families experiencing homelessness? Researchers collected qualitative data through focus groups and interviews with 31 participants, 23 families experiencing homelessness, two landlords, six case managers, and service providers. Lastly, we identify recommendations for program improvements based on information gathered from research participants. It is our hope that the information presented in this article can and will be used in a way that improves public health by increasing the residential security of families experiencing homelessness.

Improving SBIRT in a nurse-managed clinic serving homeless patients with substance use disorder

A nurse-managed clinic in Northeast Tennessee that mainly serves unstably housed patients launched a process improvement project to evaluate Screening, Brief Intervention, and Referral to Treatment (SBIRT) implementation and use. These findings could guide future SBIRT efforts among vulnerable groups.

Examining Recovery Program Participants by Gender: Program Completion, Relapse, and Multidimensional Status 12 Months After Program Entry

This study examined individual-level characteristics and factors associated with program completion, relapse, and multidimensional status at follow-up for 213 men and 248 women who entered one of 17 peer-led recovery programs and who completed a follow-up interview 12 months later. Study results found that although there were some significant gender differences at program entry among participants entering Recovery Kentucky, there were few gender differences at follow-up. In addition, although participants had significant psychosocial problems, polysubstance use patterns, and severe substance use disorder (SUD), the majority of both men and women reported completing the program (80.3%), a small minority reported relapse (9.5%), and about one third had worse multidimensional status about 12 months after program entry. Lower quality of life rating at program entry was associated with program completion and with better multidimensional status at follow-up. Study results suggest the recovery program provides an important option for some of the most vulnerable individuals with SUD.

Understanding the Collaborative Planning Process in Homeless Services: Networking, Advocacy, and Local Government Support May Reduce Service Gaps

OBJECTIVE

The Continuum of Care (CoC) process-a nationwide system of regional collaborative planning networks addressing homelessness-is the chief administrative method utilized by the US Department of Housing and Urban Development to prevent and reduce homelessness in the United States. The objective of this study is to provide a benchmark comprehensive picture of the structure and practices of CoC networks, as well as information about which of those factors are associated with lower service gaps, a key goal of the initiative.

DESIGN

A national survey of the complete population of CoCs in the United States was conducted in 2014 (n = 312, 75% response rate). This survey is the first to gather information on all available CoC networks. Ordinary least squares (OLS) regression was used to determine the relationship between internal networking, advocacy frequency, government investment, and degree of service gaps for CoCs of different sizes.

SETTING

United States.

PARTICIPANTS

Lead contacts for CoCs (n = 312) that responded to the 2014 survey.

MAIN OUTCOME MEASURE

Severity of regional service gaps for people who are homeless.

RESULTS

Descriptive statistics show that CoCs vary considerably in regard to size, leadership, membership, and other organizational characteristics. Several independent variables were associated with reduced regional service gaps: networking for small CoCs (β = -.39, P < .05) and local government support for midsized CoCs (β = -.10, P < .05). For large CoCs, local government support was again significantly associated with lower service gaps, but there was also a significant interaction effect between advocacy and networking (β = .04, P < .05).

CONCLUSIONS

To reduce service gaps and better serve the homeless, CoCs should consider taking steps to improve networking, particularly when advocacy is out of reach, and cultivate local government investment and support.

What constitutes effective problematic substance use treatment from the perspective of people who are homeless? A systematic review and meta-ethnography

Background

People experiencing homelessness have higher rates of problematic substance use but difficulty engaging with treatment services. There is limited evidence regarding how problematic substance use treatment should be delivered for these individuals. Previous qualitative research has explored perceptions of effective treatment by people who are homeless, but these individual studies need to be synthesised to generate further practice-relevant insights from the perspective of this group.

Methods

Meta-ethnography was conducted to synthesise research reporting views on substance use treatment by people experiencing homelessness. Studies were identified through systematic searching of electronic databases (CINAHL; Criminal Justice Abstracts; Health Source; MEDLINE; PsycINFO; SocINDEX; Scopus; and Web of Science) and websites and were quality appraised. Original participant quotes and author interpretations were extracted and coded thematically. Concepts identified were compared to determine similarities and differences between studies. Findings were translated (reciprocally and refutationally) across studies, enabling development of an original over-arching line-of-argument and conceptual model.

Results

Twenty-three papers published since 2002 in three countries, involving 462 participants, were synthesised. Findings broadly related, through personal descriptions of, and views on, the particular intervention components considered effective to people experiencing homelessness. Participants of all types of interventions had a preference for harm reduction-oriented services. Participants considered treatment effective when it provided a facilitative service environment; compassionate and non-judgemental support; time; choices; and opportunities to (re)learn how to live. Interventions that were of longer duration and offered stability to service users were valued, especially by women. From the line-of-argument synthesis, a new model was developed highlighting critical components of effective substance use treatment from the service user’s perspective, including a service context of good relationships, with person-centred care and an understanding of the complexity of people’s lives.

Conclusion

This is the first meta-ethnography to examine the components of effective problematic substance use treatment from the perspective of those experiencing homelessness. Critical components of effective problematic substance use treatment are highlighted. The way in which services and treatment are delivered is more important than the type of treatment provided. Substance use interventions should address these components, including prioritising good relationships between staff and those using services, person-centred approaches, and a genuine understanding of individuals’ complex lives.

Homelessness-'It will crumble men': The views of staff and service users about facilitating the identification and support of people with an intellectual disability in homeless services

People with an intellectual disability (ID) face significant health inequalities and barriers to accessing appropriate support, which are made worse if the person is also homeless. An important barrier is that services may not recognise that the person has ID. This qualitative study explored the views of staff members and service users about the identification and support needs of homeless people with ID and the role of an ID screening questionnaire as a way to help improve service provision. Semi-structured interviews were conducted with 16 staff members and 8 service users from homeless services in the South East of Scotland between March 2017 and 2018. Thematic analysis identified four themes: 'not diagnosed or declared', which explored the barriers to support due to the person's ID not being identified by others or disclosed by the person; 'It will crumble men', which reported on the additional challenges faced by homeless people with ID; 'disabling environment' which identified the ways in which organisations can make support difficult for people with ID to access; and 'It's not against them, it's to help them' which explored the benefits and issues associated with screening for ID in homeless services. The results identified the complex support needs likely to be experienced by many homeless people with ID and suggested a number of implications for practice. First, the screening tool was seen as having a number of benefits, if used where there is a process to provide the person with further specialist assessment and support. Second, staff members identified a need for training in relation to identifying and supporting this group of people. Third, the screening tool was seen as a way to help provide information about the prevalence and needs of people with ID, in order to inform and shape policy, service development, and delivery.

What happens to agreement over time? A longitudinal study of self-reported substance use compared to saliva toxicological testing among subsidized housing residents

The agreement between self-reported and toxicologically verified substance use provides important information about the validity of self-reported use. While some studies report aggregate agreement across follow-up points, only a few have examined the agreement at each time point separately. An overall rate of agreement across time may miss changes that occur as people progress through a research study. In this study, a sample of 644 adults (43.8% male, 32.6% White, 57.0% Black, 90.2% ages 36+) residing in subsidized housing was used to determine the agreement between self-reported use and saliva toxicological testing for marijuana, cocaine, PCP, amphetamine, and methamphetamine at three different time points. Agreement between saliva toxicological testing and self-report ranged between 84.2% and 94.3% for different substances over time. Higher rates of agreement were found for cocaine than had been reported by previous studies. Statistically significant differences in the odds ratios of concordance over time (baseline, 6-month, and 12-month follow-up) were found for marijuana and the combined category for PCP, amphetamine, and methamphetamine. Our findings suggest that oral fluid drug tests generally withstand community field assessments and result in relatively high levels of agreement for marijuana, cocaine, PCP, amphetamine, and methamphetamine use, when compared to self-report. Because of the ease of sample collection and low chance of adulteration, we conclude that saliva testing is a viable method for toxicological confirmation of substance use behavior in this setting.

Permanent Supportive Housing and Specialized Co-Occurring Disorders Wraparound Services for Homeless Individuals

OBJECTIVE

Among individuals experiencing chronic homelessness, there is a high rate of co-occurring mental health and substance use, which has traditionally been addressed through the delivery of permanent supportive housing along with substance use and mental health services. However, this population often has difficulty engaging in treatment for co-occurring disorders, which can result in exacerbation of symptoms and housing loss. Maintaining Independence and Sobriety Through Systems Integration, Outreach, and Networking (MISSION) is a co-occurring mental health and substance use wraparound approach that was pilot-tested alongside Permanent Supportive Housing (PSH) to improve treatment access and engagement. This pilot was part of a state plan to end homelessness in the Boston metro area.

METHODS

This open pilot study enrolled 136 individuals who were chronically homeless and offered one year of MISSION along with PSH. Program participants also received baseline and 6- and 12-month follow-up assessments.

RESULTS

At one-year follow-up, 82.4% of the program participants were housed in PSH. However, due to limited affordable housing in the Boston metro area, it took on average 6.20 months to house the program participants. Furthermore, while MISSION was feasible to implement alongside PSH, fidelity to the MISSION model was lower than expected. This pilot also examined the role of housing status on clinical outcomes and found that the program participants who were housed at the time of discharge displayed a statistically significant improvement in emergency room visits for mental health complaints, the Psychosis subscale of the Behavior and Symptom Identification Scale (BASIS-32), illegal drug use, and pharmacotherapy treatment.

CONCLUSIONS

This pilot study demonstrated that systematically integrating PSH and MISSION can improve access and engagement in care, housing retention, and mental health outcomes. Despite the preliminary success and while taking into account the limitations of the open single-group pre/post design, this study also identified the lack of affordable housing as a potential barrier to placement as well as the critical role of housing for improved clinical outcomes. Randomized controlled trials are needed to test MISSION with PSH as well as perhaps PSH with and without MISSION to tease apart the effects of integrating both approaches simultaneously.

What Happens After Treatment? Long-Term Effects of Continued Substance Use, Psychiatric Problems and Help-Seeking on Social Status of Alcohol-Dependent Individuals

PURPOSE

We examined whether alcohol-dependent individuals with sustained substance use or psychiatric problems after completing treatment were more likely to experience low social status and whether continued help-seeking would improve outcomes.

SHORT SUMMARY

Ongoing alcohol, drug and psychiatric problems after completing treatment were associated with increased odds of low social status (unemployment, unstable housing and/or living in high-poverty neighborhood) over 7 years. The impact of drug problems declined over time, and there were small, delayed benefits of AA attendance on social status.

METHOD

Alcohol-dependent individuals sampled from public and private treatment programs (N = 491; 62% male) in Northern California were interviewed at treatment entry and 1, 3, 5 and 7 years later. Random effects models tested relationships between problem severity (alcohol, drug and psychiatric problems) and help-seeking (attending specialty alcohol/drug treatment and Alcoholics Anonymous, AA) with low social status (unemployment, unstable housing and/or living in a high-poverty neighborhood) over time.

RESULTS

The proportion of participants experiencing none of the indicators of low social status increased between baseline and the 1-year follow-up and remained stable thereafter. Higher alcohol problem scores and having any drug and/or psychiatric problems in the years after treatment were associated with increased odds of low social status over time. An interaction of drug problems with time indicated the impact of drug problems on social status declined over the 7-year period. Both treatment-seeking and AA attendance were associated with increased odds of low social status, although lagged models suggested there were small, delayed benefits of AA attendance on improved social status over time.

CONCLUSION

Specialty addiction treatment alone was not sufficient to have positive long-term impacts on social status and social integration of most alcohol-dependent people.

Concurrent Disorders and Health Care Utilization Among Homeless and Vulnerably Housed Persons in Canada

OBJECTIVE

Individuals who are homeless or vulnerably housed have a higher prevalence of concurrent disorders, defined as having a mental health diagnosis and problematic substance use, compared to the general housed population. The study objective was to investigate the effect of having concurrent disorders on health care utilization among homeless or vulnerably housed individuals, using longitudinal data from the Health and Housing in Transition Study.

METHODS

In 2009, 1190 homeless or vulnerably housed adults were recruited in Ottawa, Toronto, and Vancouver, Canada. Participants completed baseline interviews and four annual follow-up interviews, providing data on sociodemographics, housing history, mental health diagnoses, problematic drug use with the Drug Abuse Screening Test (DAST-10), problematic alcohol use with the Alcohol Use Disorders Identification Test (AUDIT), chronic health conditions, and utilization of the following health care services: emergency department (ED), hospitalization, and primary care. Concurrent disorders were defined as the participant having ever received a mental health diagnosis at baseline and having problematic substance use (i.e., DAST-10 ≥ 6 and/or AUDIT ≥ 20) at any time during the study period. Three generalized mixed effects logistic regression models were used to examine the independent association of having concurrent disorders and reporting ED use, hospitalization, or primary care visits in the past 12 months.

RESULTS

Among our sample of adults who were homeless or vulnerably housed, 22.6% (n = 261) reported having concurrent disorders at baseline. Individuals with concurrent disorders had significantly higher odds of ED use (adjusted odds ratio [AOR] = 1.71; 95% confidence interval [CI], 1.4-2.11), hospitalization (AOR = 1.45; 95% CI, 1.16-1.81), and primary care visits (AOR = 1.34; 95% CI, 1.05-1.71) in the past 12 months over the four-year follow-up period, after adjusting for potential confounders.

CONCLUSIONS

Concurrent disorders were associated with higher rates of health care utilization when compared to those without concurrent disorders among homeless and vulnerably housed individuals. Comprehensive programs that integrate mental health and addiction services with primary care as well as community-based outreach may better address the unmet health care needs of individuals living with concurrent disorders who are vulnerable to poor health outcomes.

Role of recovery residences in criminal justice reform

Over the past decade there has been a clear consensus among drug policy researchers that the practice of incarcerating persons for drug offenses has been counterproductive. As a result, U.S. criminal justice policy is increasingly emphasizing alternative dispositions to incarceration for drug related arrests. In addition, large numbers of persons currently incarcerated for drug related offenses are being released into communities. However, there are serious questions about where these individuals are going to live once released and how they will access needed services. Residential recovery homes in the community are good options for those who wish to pursue abstinence from drugs. They provide a drug- and alcohol-free living environment along with social support for abstinence and successful functioning in the community. This paper reviews recent changes in drug policy the U.S. and describes the variety of recovery home options that are available to persons diverted or released from incarceration.

The Architecture of Recovery: Two Kinds of Housing Assistance for Chronic Homeless Persons with Substance Use Disorders

PURPOSE

Roughly half a million persons in the United States are homeless on any given night and over a third of those individuals have significant alcohol/other drug (AOD) problems. Many are chronically homeless and in need of assistance for a variety of problems. However, the literature on housing services for this population has paid limited attention to comparative analyses contrasting different approaches.

APPROACH

We examined the literature on housing models for homeless persons with AOD problems and critically analyzed how service settings and operations aligned with service goals.

FINDINGS

We found two predominant housing models that reflect different service goals: Sober Living Houses (SLHs) and Housing First (HF). SLHs are communally based living arrangements that draw on the principles of Alcoholics Anonymous. They emphasize a living environment that promotes abstinence and peer support for recovery. HF is based on the premise that many homeless persons with substance abuse problems will reject abstinence as a goal. Therefore, the HF focus is providing subsidized or free housing and optional professional services for substance abuse, psychiatric disorders and other problems.

PRACTICAL IMPLICATIONS

If homeless service providers are to develop comprehensive systems for homeless persons with AOD problems, they need to consider important contrasts in housing models, including definitions of "recovery," roles of peer support, facility management, roles for professional service, and the architectural designs that support the mission of each type of housing.

ORIGINALITY

This paper is the first to consider distinct consumer choices within homeless service systems and provide recommendations to improve each based upon an integrated analysis that considers how architecture and operations align with service goals.

Utilization of a Sobering Center for Acute Alcohol Intoxication

OBJECTIVE

The objective was to describe the population utilizing a sobering center for public alcohol intoxication and compare between single-visit users, repeat users, and high users.

METHODS

We conducted a secondary analysis of 1,271 adults cared for in a sobering center from July 2014 to June 2015. We divided the population into three groups-single use (one visit), repeat users (two to five visits), and high (six or more) users-and evaluated demographics, lifetime health diagnoses utilizing the Elixhauser Comorbidity Index, rates of public service utilization including ambulance and emergency department, and related costs.

RESULTS

The population was primarily male, middle-aged, and ethnically diverse. Compared to single-visit users (n = 869), repeat (n = 287) and high users (n = 115) were older, were more likely to be currently homeless, and had spent more time homeless. Repeat and high users had significantly higher rates of hypertension, liver disease, diabetes, depression, psychoses, and drug abuse diagnoses compared to single-visit users. In addition to sobering visits, utilization of ambulance and ED and related costs were significantly greater for the high users compared to repeat and single-visit users.

CONCLUSIONS

From an overall heterogeneous population, more frequent utilizers of the sobering center, both high and repeat users compared to low users, had significantly greater prevalence of chronic disorders, service utilization, and homelessness. Findings indicate that a sobering center can have a prominent role in the care for those with acute alcohol intoxication, particularly those individuals with chronic public intoxication who are likewise homeless. Further longitudinal research could offer important insights as to the population served over time, investigating changes in utilization and efforts toward health and housing stabilization.

Housing Status, Psychiatric Symptoms, and Substance Abuse Outcomes Among Sober Living House Residents over 18 Months

Studies show individuals entering sober living recovery houses (SLHs) make significant, sustained improvement on measures of substance abuse problems, employment, and arrests. The current study assessed changes in housing status among SLH residents over 18 months and the relative influences of housing status and psychiatric distress on substance abuse outcomes. Two hundred forty one men and 58 women, all age 18 and older, were interviewed within their first week of entering 20 SLHs and again at 6-, 12-, and 18-month follow-up. Between entry into the SLHs and 18-month follow-up homelessness declined from 16% to 4%, marginal housing declined from 66% to 46%, and stable housing increased from 13% to 27%. Psychiatric severity was generally mild to moderate in severity, but nevertheless showed improvement over the 18-month study period. Multivariate models showed worse substance abuse outcomes for residents with higher psychiatric distress and unstable housing. Relative to persons with stable housing, those who were homeless or marginally housed had worse outcomes and those in SLHs had better outcomes. Overall, we conclude that individuals entering SLHs show improvement in housing status and psychiatric distress, both of which are associated with better substance abuse outcomes.

What's the agreement between self-reported and biochemical verification of drug use? A look at permanent supportive housing residents

Self-reported substance use is commonly used as an outcome measure in treatment research. We evaluated the validity of self-reported drug use in a sample of 334 adults with mental health problems who were residing in supportive housing programs. The primary analysis was the calculation of the positive predictive values (PPVs) of self-report compared to an oral fluid test taken at the same time. A sensitivity analysis compared the positive predictive values of two self-reported drug use histories: biological testing window (ranging between the past 96h to 30days depending on drug type) or the full past 90-day comparison window (maximum length recorded during interview). A multivariable logistic regression was used to predict discordance between self-report and the drug test for users. Self-reported drug use and oral fluid drug tests were compared to determine the positive predictive value for amphetamines/methamphetamines/PCP (47.1% agreement), cocaine (43.8% agreement), and marijuana (69.7% agreement) drug tests. Participants who misreported their drug use were more likely to be older, non-White, have no medical insurance, and not report any alcohol use. In general, amphetamine/methamphetamine/PCP and cocaine use was adequately captured by the biological test, while marijuana use was best captured by a combination of self-report and biological data. Using the full past 90day comparison window resulted in higher concordance with the oral fluid drug test, indicating that self-reported drug use in the past 90days may be a proxy for drug use within the biological testing window. Self-report has some disadvantages when used as the sole measure of drug use in this population.
