A multi-site comparison of supported housing for chronically homeless adults: "Housing first" versus "residential treatment first"

Life is better but not without challenges: experiences following discharge from community-based residential mental health rehabilitation-a qualitative content analysis

PURPOSE

Community-based residential mental health rehabilitation units for people experiencing severe and persistent mental illness are increasingly available in Australia. Research completed 20 years ago suggested that people leaving these services often experienced impoverished social lives and other challenges in the community. It is unclear whether contemporary consumers experience similar difficulties. This qualitative study explored contemporary consumers' experiences after leaving community-based residential services.

METHODS

An inductive qualitative content analysis of individual interviews was completed with consumers 12-18 months following discharge from three community care units (CCUs) in Queensland, Australia. The interview schedule explored three questions: (1) What does life look like after leaving the CCU, (2) Has the CCU impacted their life, and (3) How could the CCU experience be improved? A convenience sample was used, with sampling continuing until thematic saturation was achieved. A member of the research team who had relevant lived experience actively supported the analysis and interpretation.

RESULTS

Seventeen interviews were completed. Three themes were identified: 'life is better but not without challenges', 'the CCU helps you get ready to go out into the world', and 'strict rules are important but rigid expectations can be hard; things could be better'.

CONCLUSION

Consumers reflected positively on their lives post-discharge from a community-based residential rehabilitation unit and viewed the service as having supported improvements in their lives. The findings suggest the appropriateness of optimism about the possibility of sustained improvements in quality of life after leaving community-based transitional residential rehabilitation support.

The effectiveness of abstinence-based and harm reduction-based interventions in reducing problematic substance use in adults who are experiencing homelessness in high income countries: A systematic review and meta-analysis: A systematic review

Background

Homelessness is a traumatic experience, and can have a devastating effect on those experiencing it. People who are homeless often face significant barriers when accessing public services, and have often experienced adverse childhood events, extreme social disadvantage, physical, emotional and sexual abuse, neglect, low self-esteem, poor physical and mental health, and much lower life expectancy compared to the general population. Rates of problematic substance use are disproportionately high, with many using drugs and alcohol to deal with the stress of living on the street, to keep warm, or to block out memories of previous abuse or trauma. Substance dependency can also create barriers to successful transition to stable housing.

Objectives

To understand the effectiveness of different substance use interventions for adults experiencing homelessness.

Search Methods

The primary source of studies for was the 4th edition of the Homelessness Effectiveness Studies Evidence and Gaps Maps (EGM). Searches for the EGM were completed in September 2021. Other potential studies were identified through a call for grey evidence, hand-searching key journals, and unpacking relevant systematic reviews.

Selection Criteria

Eligible studies were impact evaluations that involved some comparison group. We included studies that tested the effectiveness of substance use interventions, and measured substance use outcomes, for adults experiencing homelessness in high income countries.

Data Collection and Analysis

Descriptive characteristics and statistical information in included studies were coded and checked by at least two members of the review team. Studies selected for the review were assessed for confidence in the findings. Standardised effect sizes were calculated and, if a study did not provide sufficient raw data for the calculation of an effect size, author(s) were contacted to obtain these data. We used random-effects meta-analysis and robust-variance estimation procedures to synthesise effect sizes. If a study included multiple effects, we carried out a critical assessment to determine (even if only theoretically) whether the effects are likely to be dependent. Where dependent effects were identified, we used robust variance estimation to determine whether we can account for these. Where effect sizes were converted from a binary to continuous measure (or vice versa), we undertook a sensitivity analysis by running an additional analysis with these studies omitted. We also assessed the sensitivity of results to inclusion of non-randomised studies and studies classified as low confidence in findings. All included an assessment of statistical heterogeneity. Finally, we undertook analysis to assess whether publication bias was likely to be a factor in our findings. For those studies that we were unable to include in meta-analysis, we have provided a narrative synthesis of the study and its findings.

Main Results

We included 48 individual papers covering 34 unique studies. The studies covered 15, 255 participants, with all but one of the studies being from the United States and Canada. Most papers were rated as low confidence (n = 25, or 52%). By far the most common reason for studies being rated as low confidence was high rates of attrition and/or differential attrition of study participants, that fell below the What Works Clearinghouse liberal attrition standard. Eleven of the included studies were rated as medium confidence and 12 studies as high confidence. The interventions included in our analysis were more effective in reducing substance use than treatment as usual, with an overall effect size of -0.11 SD (95% confidence interval [CI], -0.27, 0.05). There was substantial heterogeneity across studies, and the results were sensitive to the removal of low confidence studies (-0.21 SD, 95% CI [-0.59, 0.17] - 6 studies, 17 effect sizes), the removal of quasi-experimental studies (-0.14 SD, 95% CI [-0.30, 0.02] - 14 studies, 41 effect sizes) and the removal of studies where an effect size had been converted from a binary to a continuous outcome (-0.08 SD, 95% CI [-0.31, 0.15] - 10 studies, 31 effect sizes). This suggests that the findings are sensitive to the inclusion of lower quality studies, although unusually the average effect increases when we removed low confidence studies. The average effect for abstinence-based interventions compared to treatment-as-usual (TAU) service provision was -0.28 SD (95% CI, -0.65, 0.09) (6 studies, 15 effect sizes), and for harm reduction interventions compared to a TAU service provision is close to 0 at 0.03 SD (95% CI, -0.08, 0.14) (9 studies, 30 effect sizes). The confidence intervals for both estimates are wide and crossing zero. For both, the comparison groups are primarily abstinence-based, with the exception of two studies where the comparison group condition was unclear. We found that both Assertative Community Treatment and Intensive Case Management were no better than treatment as usual, with average effect on substance use of 0.03 SD, 95% CI [-0.07, 0.13] and -0.47 SD, 95% CI [-0.72, -0.21] 0.05 SD, 95% CI [-0.28, 0.39] respectively. These findings are consistent with wider research, and it is important to note that we only examined the effect on substance use outcomes (these interventions can be effective in terms of other outcomes). We found that CM interventions can be effective in reducing substance use compared to treatment as usual, with an average effect of -0.47 SD, 95% CI (-0.72, -0.21). All of these results need to be considered in light of the quality of the underlying evidence. There were six further interventions where we undertook narrative synthesis. These syntheses suggest that Group Work, Harm Reduction Psychotherapy, and Therapeutic Communities are effective in reducing substance use, with mixed results found for Motivational Interviewing and Talking Therapies (including Cognitive Behavioural Therapy). The narrative synthesis suggested that Residential Rehabilitation was no better than treatment as usual in terms of reducing substance use for our population of interest.

Authors' Conclusions

Although our analysis of harm reduction versus treatment as usual, abstinence versus treatment as usual, and harm reduction versus abstinence suggests that these different approaches make little real difference to the outcomes achieved in comparison to treatment as usual. The findings suggest that some individual interventions are more effective than others. The overall low quality of the primary studies suggests that further primary impact research could be beneficial.

Improving oral health and related health behaviours (substance use, smoking, diet) in people with severe and multiple disadvantage: A systematic review of effectiveness and cost-effectiveness of interventions

BACKGROUND

People experiencing homelessness co-occurring with substance use or offending ('severe and multiple disadvantage' SMD) often have high levels of poor oral health and related health behaviours (particularly, substance use, smoking, poor diet). This systematic review aimed to assess the effectiveness and cost-effectiveness of interventions in adults experiencing SMD to improve oral health and related health behaviours.

METHODS AND FINDINGS

From inception to February 2023, five bibliographic databases (MEDLINE, EMBASE, PsycINFO, CINAHL, and Scopus) and grey literature were searched. Two researchers independently screened the search results. Randomized controlled trials (RCTs), comparative studies and economic evaluations were included that reported outcomes on oral health and the related health behaviours. Risk of bias was assessed and results narratively synthesized. Meta-analyses were performed where appropriate. This review was registered with PROSPERO (reg. no: CRD42020202416). Thirty-eight studies were included (published between 1991 and 2023) with 34 studies reporting about effectiveness. Most studies reported on substance use (n = 30). Interventions with a combination of housing support with substance use and mental health support such as contingent work therapy appeared to show some reduction in substance use in SMD groups. However, meta-analyses showed no statistically significant results. Most studies had short periods of follow-up and high attrition rates. Only one study reported on oral health; none reported on diet. Three RCTs reported on smoking, of which one comprising nicotine replacement with contingency management showed improved smoking abstinence at 4 weeks compared to control. Five studies with economic evaluations provided some evidence that interventions such as Housing First and enhanced support could be cost-effective in reducing substance use.

CONCLUSION

This review found that services such as housing combined with other healthcare services could be effective in improving health behaviours, particularly substance use, among SMD groups. Gaps in evidence also remain on oral health improvement, smoking, and diet. High quality studies on effectiveness with adequate power and retention are needed to address these significant health challenges in SMD populations.

Interventions to improve the mental health of women experiencing homelessness: A systematic review of the literature

BACKGROUND

Homelessness is a growing public health challenge in the United Kingdom and internationally, with major consequences for physical and mental health. Women represent a particularly vulnerable subgroup of the homeless population, with some evidence suggesting that they suffer worse mental health outcomes than their male counterparts. Interventions aimed at improving the lives of homeless women have the potential to enhance mental health and reduce the burden of mental illness in this population. This review synthesised the evidence on the effectiveness and acceptability of interventions which aim to improve mental health outcomes in homeless women.

METHODS

Five electronic bibliographic databases: MEDLINE, PsycInfo, CINAHL, ASSIA and EMBASE, were searched. Studies were included if they measured the effectiveness or acceptability of any intervention in improving mental health outcomes in homeless women. Study quality was assessed using the Effective Public Health Practice Project (EPHPP) Quality Assessment Tool. A narrative summary of the study findings in relation to the research questions was produced.

RESULTS

Thirty-nine studies met inclusion criteria. Overall, there was moderate evidence of the effectiveness of interventions in improving mental health outcomes in homeless women, both immediately post-intervention and at later follow-up. The strongest evidence was for the effectiveness of psychotherapy interventions. There was also evidence that homeless women find interventions aimed at improving mental health outcomes acceptable and helpful.

CONCLUSIONS

Heterogeneity in intervention and study methodology limits the ability to draw definitive conclusions about the extent to which different categories of intervention improve mental health outcomes in homeless women. Future research should focus on lesser-studied intervention categories, subgroups of homeless women and mental health outcomes. More in-depth qualitative research of factors that enhance or diminish the acceptability of mental health interventions to homeless women is also required.

Rates and Predictors of Returns to Homelessness Among Veterans, 2018-2022

INTRODUCTION

The progress made by the U.S. Department of Veterans Affairs toward ending veteran homelessness requires that attention be paid to preventing returns to homelessness.

METHODS

Using national Veterans Affairs data on 293,820 exits from a Veterans Affairs homeless program to a permanent housing destination between January 2018 and December 2022, rates and predictors of returns to homelessness among veterans were examined. Analyses were conducted in June-August 2023. A return to homelessness was operationally defined as a return encounter with a Veterans Affairs homeless program.

RESULTS

A total of 5.8% of successful exits to permanent housing resulted in a return to homelessness within 6 months, 10.2% resulted in a return within 12 months, and 16.7% resulted in a return within 24 months. In the total sample, veterans who were male (hazard ratio=1.47), were widowed (hazard ratio=1.29), had diagnoses of drug use disorder (hazard ratio=1.40) or psychotic disorder (hazard ratio=1.20), and had used more inpatient or urgent care services in the previous year (hazard ratio=1.05-1.15) were at significantly greater risk of returning to homelessness. Many of these predictors remained significant in subgroup analyses of female veterans, veterans aged ≥65 years, and veterans in the Housing and Urban Development-Veterans Affairs Supportive Housing program.

CONCLUSIONS

Most homeless veterans served by Veterans Affairs who exit to permanent housing do not return to homelessness within two years. The most critical period seems to be the first year, when 1 in 10 veterans return to homelessness. Knowledge of these risk factors may be important in planning secondary and tertiary prevention efforts for homelessness.

The mediating role of social support in associations between childhood adversity, military sexual trauma, and homelessness in a nationally representative sample of US veterans

Among veterans, availability of social support and histories of military sexual trauma (MST) and/or adverse childhood experiences (ACEs) are particularly salient correlates of homelessness. Using path analyses, we investigated whether social support (i.e., interpersonal social support and community integration) would at least partially account for the relationships of MST and ACEs with any lifetime homelessness in a large, nationally representative sample of veterans (N = 4069, 9.8% female). Interpersonal social support and community integration partially explained the relationship between ACEs and any lifetime homelessness. However, they did not mediate the relationship between MST and any lifetime homelessness. Female veterans also reported higher trauma rates and lower perceived social support than male counterparts during correlational analyses. These results reinforce existing literature on the importance of research and interventions tailored to veterans with low social support and integration. Results have potential to inform interventions and policy for veterans experiencing and/or at risk for homelessness.

A systematic review of approaches to improve medication adherence in homeless adults with psychiatric disorders

Introduction

Medication non-adherence is a significant problem among homeless individuals with psychiatric disorders in the United States. We conducted a systematic review to identify strategies to improve psychiatric medication adherence among homeless individuals with psychiatric disorders, including substance use disorders.

Methods

We searched seven databases (MEDLINE, Embase, PsychInfo, Scopus, Web of Science, CDSR, and CENTRAL) and screened 664 studies by title and abstract followed by full-text review. Our inclusion criteria were studies that: involved an intervention for homeless adults with psychiatric disorders, reported a quantitative outcome of medication adherence, and were published in English in a peer-reviewed journal. We rated the relative effectiveness of strategies described in each study using a self-designed scale.

Results

Eleven peer-reviewed studies met criteria for inclusion in this review. Within these studies, there were seven different approaches to improve medication adherence in this population. Three studies were randomized controlled trials (RCTs) and the remaining were observational studies. Outpatient interventions included Assertive Community Treatment, Cell Phone-Assisted Monitoring, Customized Adherence Enhancement plus Long-Acting Injectable Medications, and Homeless-Designated Pharmacy Clinics. Residential, shelter-based, and inpatient interventions included use of the Housing First model, Modified Therapeutic Communities, and Homeless-Designated Inpatient Care. The approaches described in four of the eleven studies were rated as scoring a 3 or higher on a 5-point scale of effectiveness in improving medication adherence; none received 5 points.

Discussion

The interventions with the strongest evidence for improving medication adherence in this population were Assertive Community Treatment, Customized Adherence Enhancement plus Long-Acting Injectable Medications, and Housing First. Overall, studies on this topic required more rigor and focus on medication adherence as an outcome in this population. This review highlights several promising strategies and the need for larger RCTs to determine effective and diverse ways to improve medication adherence among homeless adults with psychiatric disorders.

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.

Is it Time to Antiquate the Term "Landlord?"

With the growth of community partnerships with housing providers to address social determinants of health, it may be time to rethink the term "landlord." The term, landlord, may be antiquated as it originated from medieval Europe in the 9th century, denotes rank, is male, and may create further divisions between tenants and landlords. In the US, many average Americans rent their property; as data from the Internal Revenue Service and the Rental Housing Finance Survey indicate nearly 10 million Americans reported rental income in 2020 and most of them own only 1-2 rental units. This commentary argues that the term "landlord" is no longer relevant, may be counterproductive to building a culture of health across stakeholder groups, and should be replaced. Some alternative terms are suggested, including "lessor" or "rental host." Accurate and neutral terms may be useful in engaging renters and property owners in addressing housing and homelessness issues in society.

Prevalence of eviction, home foreclosure, and homelessness among low-income US veterans: the National Veteran Homeless and Other Poverty Experiences study

OBJECTIVES

Housing stability is essential for health and social well-being, and the United States is focused on preventing homelessness among veterans, so this study examined the prevalence of different events related to housing instability among low-income US veterans.

STUDY DESIGN

This was a nationally representative survey.

METHODS

Using a sample of 1004 low-income veterans in 2021, this study examined the lifetime prevalence and characteristics associated with eviction, home foreclosure, and homelessness among low-income US veterans.

RESULTS

In the total sample, 10.9% reported a lifetime history of eviction, 8.0% reported a lifetime history of home foreclosure, and 19.9% reported a lifetime history of homelessness. Among those with a history of homelessness, 39.2% also reported a history of eviction, and 13.9% reported a history of home foreclosure. Hierarchical logistic regression analyses found that for eviction, sociodemographic characteristics (e.g. being Hispanic, having private insurance, and being from the Northeast was associated with lower risk of eviction) together explained 26% of the variance, and clinical characteristics explained an incremental 12% additional variance. For homelessness, sociodemographic characteristics explained 18% of the variance, and clinical characteristics explained an incremental 20% (e.g. diagnosis of schizophrenia or bipolar disorder, any history of suicide attempt, and lower physical health scores were associated with higher risk of homelessness). For home foreclosure, sociodemographic, clinical, and psychosocial variables together only explained 14% of the variance.

CONCLUSION

Evictions, home foreclosures, and homelessness are discrete events and occur at relatively high rates among low-income veterans. In addition, homelessness was more associated with biosocial dysfunction, whereas eviction was more closely associated with socio-economic vulnerability, which may inform intervention efforts for both events.

Primary care embedded within permanent supportive housing for people who use substances: A qualitative study examining healthcare access in Vancouver, Canada

Marginally housed people who use drugs and alcohol (PWUD/A) face barriers in accessing healthcare services, which may be improved by providing healthcare in housing settings. This case study examines the experiences of healthcare access amongst PWUD/A who live in a permanent supportive housing model in Vancouver, Canada. This model has an embedded multidisciplinary clinic providing in-reach services. Thirty participants were recruited via posters placed throughout the building and semi-structured qualitative interviews were conducted remotely. Interviews were conducted with participants who accessed onsite care regularly (n = 15) and those who do not (n = 15). Data were analysed to identify both a priori and emerging themes. Participants who accessed the onsite clinic reported benefiting from stigma-free care. Close proximity and convenience of drop-in appointments enabled participants to engage with healthcare services more consistently, though hours of operation and privacy concerns were barriers for others. Participants who did not use the onsite clinic highlighted the importance of continuity of care with their pre-existing primary care team, particularly if their clinic was in close geographic proximity. However, they also described utilising these services for urgent health needs or as an occasional alternative source of care. Shared perspectives across all participants emphasised the importance of low-barrier services, including medication delivery, convenience and positive therapeutic relationships. Our findings suggest that embedding access to primary care within supportive housing benefits PWUD/A who have previously encountered barriers to healthcare access. This model could be implemented to prevent utilisation of acute healthcare resources and improve health outcomes amongst PWUD/A.

Cycles of instability: Proximal and distal influences on residential instability among people with histories of homelessness in three Canadian cities

People with histories of homelessness often have difficulties obtaining and maintaining adequate housing. This qualitative study examined the residential transitions of people with histories of residential instability and homelessness to understand factors contributing to the instability they experience. Interviews were conducted with 64 participants about their housing transitions, in the final year of a 4-year, prospective cohort study in three Canadian cities (Ottawa, Toronto, and Vancouver). Findings showed that participants pointed to both distal and proximal factors as affecting residential transitions, including interpersonal conflict, safety concerns, substance use, poverty, pests, and health. Many reported disconnection from their housing and a lack of improvement from one housing situation to the next, demonstrating how even when housed, instability persisted. Our study highlights the complexity associated with participants' often unplanned and abrupt residential transitions. The complex and distal issues that affect housing transitions require structural changes, in addition to individual-based interventions focused on the proximal problems.

More than a house: Women's recovery from homelessness in Australia

Recovery from homelessness for women is often a long, complex and highly individualised journey. This study investigated women's experiences of exiting homelessness and examined the factors that influenced recovery. The qualitative interpretive study involved auto-driven photo elicitation and in-depth interviews with 11 women who had previously been homeless. It took place in Australia between August 2018 and August 2019. Women took photographs that represented their experiences of exiting homelessness to guide discussion during interviews. Data were analysed using thematic analysis. Findings indicate that recovery from homelessness involves more than becoming housed. Recovery from homelessness is the overarching theme being presented, described using five subthemes: Finding the right house, Making a house a home, Connection, Building confidence and Helping others. Housing was only the starting point for recovery from homelessness for women. The women drew on their own self determination to create factors necessary for recovery from the experience of homelessness. We conclude that ongoing support is necessary to empower and assist women recovering from the traumatic experiences of homelessness. Trauma-informed care offers service providers a framework for supporting women who have lived through homelessness. Services can draw on this framework to provide support beyond the point of securing a house and assist women to create a home environment, build confidence in themselves and form connections to their community as they transition out of homelessness.

Impact of Housing First on Psychiatric Symptoms, Substance Use, and Everyday Life Skills Among People Experiencing Homelessness

The current unblinded, randomized controlled trial analyzed psychiatric symptoms, substance use, and life skills outcomes in participants after 21 months in the Housing First (HF) program. The HF group (intervention) comprised 46 participants and the treatment-as-usual (TAU) group (control) comprised 41 participants. Quantitative outcome measures were collected at baseline and 8 and 21 months. Primary outcomes were mental health and substance use. Secondary outcomes were everyday life skills. Descriptive and comparative analyses and linear regression models are presented. At 21 months, the HF group presented significantly better outcomes regarding alcohol and cannabis use than the TAU group. Moreover, the subgroup of HF participants with severe mental illness had significant improvements in psychotic symptoms, anxiety, depression, social relations, and cannabis use compared to TAU participants.

Housing First for homeless people with severe mental illness: extended 4-year follow-up and analysis of recovery and housing stability from the randomized Un Chez Soi d'Abord trial

AIMS

Housing First (HF), a recovery-oriented approach, was proven effective in stabilising housing situations of homeless individuals with severe mental disorders, yet had limited effectiveness on recovery outcomes on a short-term basis compared to standard treatment. The objective was to assess the effects of the HF model among homeless people with high support needs for mental and physical health services on recovery, housing stability, quality of life, health care use, mental symptoms and addiction issues on 4 years of data from the Un Chez Soi d'Abord trial.

METHODS

A multicentre randomised controlled trial was conducted from August 2011 to April 2018 with intent-to-treat analysis in four French cities: Lille, Marseille, Paris and Toulouse. Participants were homeless or precariously-housed patients with a DSM-IV-TR diagnosis of bipolar disorder or schizophrenia. Two groups were compared: the HF group (n = 353) had immediate access to independent housing and support from the assertive community treatment team; the Treatment-As-Usual (TAU) group (n = 350) had access to existing support and services. Main outcomes were personal recovery (Recovery Assessment Scale (RAS) scale), housing stability, quality of life (S-QoL), global physical and mental status (Medical Outcomes Study 36-item Short Form Health Survey (SF-36)), inpatient days, mental symptoms (Modified Colorado Symptom Index (MCSI)) and addictions (Mini International Neuropsychiatric Interview (MINI) and Alcohol Use Disorders Identification Test (AUDIT)). Mixed models using longitudinal and cluster designs were performed and adjusted to first age on the street, gender and mental disorder diagnosis. Models were tested for time × group and site × time interactions.

RESULTS

The 703 participants [123 (18%) female] had a mean age of 39 years (95% CI 38.0-39.5 years). Both groups improved RAS index from baseline to 48 months, with no statistically significant changes found between the HF and TAU groups over time. HF patients exhibited better autonomy (adjusted β = 2.6, 95% CI 1.2-4.1) and sentimental life (2.3, 95% CI 0.5-4.1), higher housing stability (28.6, 95% CI 25.1-32.1), lower inpatient days (-3.14, 95% CI -5.2 to -1.1) and improved SF-36 mental composite score (-0.8, 95% CI -1.6 to -0.1) over the 4-year follow-up. HF participants experienced higher alcohol consumption between baseline and 48 months. No significant differences were observed for self-reported mental symptoms or substance dependence.

CONCLUSION

Data at 4 years were consistent with 2-year follow-up data: similar improvement in personal recovery outcomes but higher housing stability, autonomy and lower use of hospital services in the HF group compared to the TAU group, with the exception of an ongoing alcohol issue. These sustained benefits support HF as a valuable intervention for the homeless patients with severe mental illness.

Being homeless at the "End" of homelessness navigating the symbolic and social boundaries of housing first

Housing First (HF) has emerged as the dominant paradigm in homelessness policy and has been praised for bringing an "end" to the homelessness crisis. Others claim, however, that HF facilitates further sociospatial exclusion of people experiencing homelessness (PEH). To advance this debate and understand HF within its larger sociological context, this article examines how HF policies translate to the lived experiences of those who remain in shelters and on the streets. Through interviews with 22 PEH, we demonstrate how HF confronts PEH with a set of strategic dilemmas that we frame using the concept of "boundary-work." First, PEH must negotiate the symbolic boundaries that HF establishes between "worthy" and "unworthy" for the purposes of distributing housing. Second, once housed, PEH face challenges in navigating the social boundaries that separate the private space of the dwelling, the transitional spaces of homelessness (e.g., streets, shelters), and the increasingly gentrified public spaces of the city. We end by discussing the implications of these findings for evaluating HF programs and demonstrating the value of a boundary-work perspective on homelessness.

Predictors of change in housing status over 12 months among individuals using emergency shelters, temporary housing or permanent housing in Quebec, Canada

Homelessness is an ongoing societal and public health problem in Canada and other countries. Housing services help homeless individuals along the transition towards stable housing, yet few studies have assessed factors that predict change in individual housing trajectories. This study identified predictors of change in housing status over 12 months for a sample of 270 currently or formerly homeless individuals using emergency shelters, temporary housing (TH) or permanent housing (PH) resources in Quebec. Participants recruited from 27 community or public organisations were interviewed between January and September 2017, and again 12 months later. Sociodemographic variables, housing history, health conditions, service use and client satisfaction were measured. Directors and programme coordinators from the selected organisations also completed a baseline questionnaire measuring strictness in residential codes of living/conduct, interorganisational collaboration and overall budget. Independent variables were organised into predisposing, enabling and needs factors, based on the Gelberg-Andersen Behavioral Model. Multilevel logistic regressions were used to test associations with the dependent variable: change in housing status over 12 months, whether positive (e.g. shelter to TH) or negative (e.g. PH to shelter). Predictors of positive change in housing status were as follows: residing in PH, being female, having children (predisposing factors); having consulted a psychologist, higher frequency in use of public ambulatory services (enabling factors); and not having physical illnesses (needs factor). The findings support strategies for helping this clientele obtain and maintain stable housing. They include deploying case managers to promote access to public ambulatory services, mainly among men or individuals without children who are less likely to seek help; greater use of primary care mental health teams; the establishment of more suitable housing for accommodating physical health problems; and reinforcing access to subsidised PH programmes.

Harm reduction outcomes and practices in Housing First: A mixed-methods systematic review

BACKGROUND

Harm reduction is a central tenet of Housing First. As the intervention has been shown to stably house people experiencing chronic homelessness across the lifespan with complex behavioural health needs, it is critical to understand the harm reduction outcomes and practices in Housing First.

METHODS

A systematic review following PRISMA guidelines was conducted of five databases: PsycINFO, MEDLINE, Embase, CINAHL, and Google Scholar. Harm reduction outcomes and practices in Housing First were examined in four domains: substance-related harms, viral health, sexual health, and harm reduction service use.

RESULTS

A total of 35 articles were included in the review, 23 of which examined harm reduction outcomes and 12 of which investigated harm reduction practices in Housing First. Harm reduction outcome studies focused mostly on nonspecific substance use problems, with Housing First being found to have minimal effects in this domain. More severe harms, such as delirium tremens and substance use-related deaths, have been minimally explored, though preliminary evidence is promising. Viral health, sexual health, and harm reduction service use outcomes were the focus of few studies. Research on harm reduction practices highlighted that Housing First providers experience both flexibility and ambiguity in their work using a harm reduction approach, and the importance of empathetic working relationships for engagement in harm reduction work.

CONCLUSIONS

Harm reduction outcomes in Housing First remain underexamined and any conclusions of the intervention's impacts in this domain would be premature. Effective harm reduction practices in Housing First require strong working relationships between staff and tenants.

Drug use, homelessness and health: responding to the opioid overdose crisis with housing and harm reduction services

Background

Canada is in the midst of an opioid overdose crisis and Alberta has one of the highest opioid use rates across the country. Populations made vulnerable through structural inequities who also use opioids, such as those who are unstably housed, are at an increased risk of experiencing harms associated with opioid use. The main purpose of this study was to explore if there was an association between unstable housing and hospital use for people who use opioids.

Methods

Analysis utilized self-reported data from the Alberta Health and Drug Use Survey which surveyed 813 Albertans in three cities. Hospital use was modeled using a logistic regression with our primary variable of interest being housing unstable status. Chi square tests were conducted between hospital use and variables associated with demographics, characteristics of drug use, health characteristics, and experiences of receiving services to establish model inclusion.

Results

Results revealed a significant association between housing instability and hospital use with unstably housed individuals twice as likely torequire hospital care.

Conclusions

Results highlight the importance of concurrently addressing housing instability alongside the provision of harm reduction services such as safe supply and supervised consumption sites. These findings have significant implications for policy and policymakers during the opioid overdose epidemic, and provide a foundation for future areas of research.

Changes in Medicaid Utilization and Spending Associated with Homeless Adults' Entry into Permanent Supportive Housing

BACKGROUND

There is growing interest in financing housing and supportive services for homeless individuals through Medicaid. Permanent Supportive Housing (PSH), which integrates non-time-limited housing with supportive services for people who are disabled and chronically homeless, has seen rapid growth in the last decade, but clear evidence on the long-term impacts of PSH, needed to guide state efforts to finance some PSH services through Medicaid, is lacking.

OBJECTIVE

Assess changes in Medicaid expenditures and utilization associated with receiving PSH.

DESIGN

Cohort study using a difference-in-differences approach.

PARTICIPANTS

A total of 1226 PA Medicaid enrollees who entered PSH 2011-2016 and remained in PSH for 180 days or more, and a matched comparison cohort of 970 enrollees experiencing housing instability who did not receive PSH.

MAIN MEASURES

Medicaid spending in aggregate, and on behavioral and physical health services; emergency department (ED) visits and inpatient hospital stays.

KEY RESULTS

Three years after PSH entry, spending decreased by an average of $145/month in the PSH cohort relative to changes in the comparison cohort (p = 0.046), with the greatest relative spending reductions occurring for residential behavioral health ($64, p < 0.001) and inpatient non-behavioral health services ($89, p = 0.001). We also found relative reductions in ED use (4.7 visits/100 person-months, p = 0.010) and inpatient hospital stays (1.6 visits/100 person-months, p < 0.001).

CONCLUSIONS

These results can inform emerging state efforts to finance PSH services through Medicaid. Additional state expenditures to expand financing for PSH services could be partially offset by reductions in Medicaid spending, in part by facilitating a shift in treatment to outpatient from acute care settings.

A comprehensive review of prioritised interventions to improve the health and wellbeing of persons with lived experience of homelessness

Background

Homelessness has emerged as a public health priority, with growing numbers of vulnerable populations despite advances in social welfare. In February 2020, the United Nations passed a historic resolution, identifying the need to adopt social-protection systems and ensure access to safe and affordable housing for all. The establishment of housing stability is a critical outcome that intersects with other social inequities. Prior research has shown that in comparison to the general population, people experiencing homelessness have higher rates of infectious diseases, chronic illnesses, and mental-health disorders, along with disproportionately poorer outcomes. Hence, there is an urgent need to identify effective interventions to improve the lives of people living with homelessness.

Objectives

The objective of this systematic review is to identify, appraise, and synthesise the best available evidence on the benefits and cost-effectiveness of interventions to improve the health and social outcomes of people experiencing homelessness.

Search Methods

In consultation with an information scientist, we searched nine bibliographic databases, including Medline, EMBASE, and Cochrane CENTRAL, from database inception to February 10, 2020 using keywords and MeSH terms. We conducted a focused grey literature search and consulted experts for additional studies.

Selection Criteria

Teams of two reviewers independently screened studies against our inclusion criteria. We included randomised control trials (RCTs) and quasi-experimental studies conducted among populations experiencing homelessness in high-income countries. Eligible interventions included permanent supportive housing (PSH), income assistance, standard case management (SCM), peer support, mental health interventions such as assertive community treatment (ACT), intensive case management (ICM), critical time intervention (CTI) and injectable antipsychotics, and substance-use interventions, including supervised consumption facilities (SCFs), managed alcohol programmes and opioid agonist therapy. Outcomes of interest were housing stability, mental health, quality of life, substance use, hospitalisations, employment and income.

Data Collection and Analysis

Teams of two reviewers extracted data in duplicate and independently. We assessed risk of bias using the Cochrane Risk of Bias tool. We performed our statistical analyses using RevMan 5.3. For dichotomous data, we used odds ratios and risk ratios with 95% confidence intervals. For continuous data, we used the mean difference (MD) with a 95% CI if the outcomes were measured in the same way between trials. We used the standardised mean difference with a 95% CI to combine trials that measured the same outcome but used different methods of measurement. Whenever possible, we pooled effect estimates using a random-effects model.

Main Results

The search resulted in 15,889 citations. We included 86 studies (128 citations) that examined the effectiveness and/or cost-effectiveness of interventions for people with lived experience of homelessness. Studies were conducted in the United States (73), Canada (8), United Kingdom (2), the Netherlands (2) and Australia (1). The studies were of low to moderate certainty, with several concerns regarding the risk of bias. PSH was found to have significant benefits on housing stability as compared to usual care. These benefits impacted both high- and moderate-needs populations with significant cimorbid mental illness and substance-use disorders. PSH may also reduce emergency department visits and days spent hospitalised. Most studies found no significant benefit of PSH on mental-health or substance-use outcomes. The effect on quality of life was also mixed and unclear. In one study, PSH resulted in lower odds of obtaining employment. The effect on income showed no significant differences. Income assistance appeared to have some benefits in improving housing stability, particularly in the form of rental subsidies. Although short-term improvement in depression and perceived stress levels were reported, no evidence of the long-term effect on mental health measures was found. No consistent impact on the outcomes of quality of life, substance use, hospitalisations, employment status, or earned income could be detected when compared with usual services. SCM interventions may have a small beneficial effect on housing stability, though results were mixed. Results for peer support interventions were also mixed, though no benefit was noted in housing stability specifically. Mental health interventions (ICM, ACT, CTI) appeared to reduce the number of days homeless and had varied effects on psychiatric symptoms, quality of life, and substance use over time. Cost analyses of PSH interventions reported mixed results. Seven studies showed that PSH interventions were associated with increased cost to payers and that the cost of the interventions were only partially offset by savings in medical- and social-services costs. Six studies revealed that PSH interventions saved the payers money. Two studies focused on the cost-effectiveness of income-assistance interventions. For each additional day housed, clients who received income assistance incurred additional costs of US$45 (95% CI, -$19, -$108) from the societal perspective. In addition, the benefits gained from temporary financial assistance were found to outweigh the costs, with a net savings of US$20,548. The economic implications of case management interventions (SCM, ICM, ACT, CTI) was highly uncertain. SCM clients were found to incur higher costs than those receiving the usual care. For ICM, all included studies suggested that the intervention may be cost-offset or cost-effective. Regarding ACT, included studies consistently revealed that ACT saved payers money and improved health outcomes than usual care. Despite having comparable costs (US$52,574 vs. US$51,749), CTI led to greater nonhomeless nights (508 vs. 450 nights) compared to usual services.

Authors' Conclusions

PSH interventions improved housing stability for people living with homelessness. High-intensity case management and income-assistance interventions may also benefit housing stability. The majority of included interventions inconsistently detected benefits for mental health, quality of life, substance use, employment and income. These results have important implications for public health, social policy, and community programme implementation. The COVID-19 pandemic has highlighted the urgent need to tackle systemic inequality and address social determinants of health. Our review provides timely evidence on PSH, income assistance, and mental health interventions as a means of improving housing stability. PSH has major cost and policy implications and this approach could play a key role in ending homelessness. Evidence-based reviews like this one can guide practice and outcome research and contribute to advancing international networks committed to solving homelessness.

The impact of a Housing First intervention and health-related risk factors on incarceration among people with experiences of homelessness and mental illness in Canada

OBJECTIVE

To examine the effect of a Housing First (HF) intervention and health-related risk factors on incarceration among adults with experiences of homelessness and mental illness.

METHODS

Participants (N = 508) were recruited at the Toronto site of the At Home/Chez Soi study. The outcome was incarceration in Ontario from 2009 to 2014. Exposures were intervention group (HF vs. treatment as usual), Axis I mental health diagnoses, emergency department (ED) visit, and history of traumatic brain injury (TBI). Logistic regression was used to examine the association between exposures and incarceration.

RESULTS

Of 508 participants, 220 (43.3%) were incarcerated at least once during the study period. Among those incarcerated, 81.9% were male, 52.7% had been diagnosed with alcohol dependence/abuse, 60.9% had been diagnosed with substance dependence/abuse, 65.1% reported having visited an ED within the last 6 months, and 66.4% had a history of TBI. After adjusting for demographic covariates, substance dependence/abuse (aOR: 2.06; 95% CI: 1.40, 3.03), alcohol dependence/abuse (aOR: 1.52, 95% CI: 1.04, 2.22), ED visit (aOR: 1.54; 95% CI: 1.02, 2.32), and history of TBI (aOR: 2.60; 95% CI: 1.75, 3.85) were associated with incarceration. We found no significant effect of the HF intervention on incarceration outcome (aOR: 1.08; 95% CI: 0.76, 1.55).

CONCLUSIONS

Among adults with experiences of homelessness and severe mental illness, those with substance and alcohol dependence/abuse disorders, history of TBI, and recent ED visits were at increased odds of incarceration. Strategies are needed to prevent and reduce incarceration for this population, including treatment of mental illness in the community.

Met and unmet needs of homeless individuals at different stages of housing reintegration: A mixed-method investigation

This study aimed to identify and compare major areas of met and unmet needs reported by 455 homeless or recently housed individuals recruited from emergency shelters, temporary housing, and permanent housing in Quebec (Canada). Mixed methods, guided by the Maslow framework, were used. Basic needs were the strongest needs category identified, followed by health and social services (an emergent category), and safety; very few participants expressed needs in the higher-order categories of love and belonging, self-esteem, and self-actualization. The only significant differences between the three housing groups occurred in basic needs met, which favored permanent housing residents. Safety was the only category where individuals reported more unmet than met needs. The study results suggested that increased overall access to and continuity of care with family physicians, MD or SUD clinicians and community organizations for social integration should be provided to help better these individuals. Case management, stigma prevention, supported employment programs, peer support and day centers should particularly be more widely implemented as interventions that may promote a higher incidence of met needs in specific needs categories.

Pharmacist led homeless outreach engagement and non-medical independent prescribing (Rx) (PHOENIx) intervention for people experiencing homelessness: a non- randomised feasibility study

BACKGROUND

Homelessness and associated mortality and multimorbidity rates are increasing. Systematic reviews have demonstrated a lack of complex interventions that decrease unscheduled emergency health services utilisation or increase scheduled care. Better evidence is needed to inform policy responses. We examined the feasibility of a complex intervention (PHOENIx: Pharmacist led Homeless Outreach Engagement Nonmedical Independent prescribing (Rx)) to inform a subsequent pilot randomised controlled trial (RCT).

METHODS

Non-randomised trial with Usual Care (UC) comparator group set in Greater Glasgow and Clyde Health Board, Scotland. Participants were adult inpatients experiencing homelessness in a city centre Glasgow hospital, referred to the PHOENIx team at the point of hospital discharge, from 19th March 2018 until 6th April 2019. The follow up period for each patient started on the day the patient was first seen (Intervention group) or first referred (UC), until 24th August 2019, the censor date for all patients. All patients were offered and agreed to receive serial consultations with the PHOENIx team (NHS Pharmacist prescriber working with Simon Community Scotland (third sector homeless charity worker)). Patients who could not be reached by the PHOENIx team were allocated to the UC group. The PHOENIx intervention included assessment of physical/mental health, addictions, housing, benefits and social activities followed by pharmacist prescribing with referral to other health service specialities as necessary. All participants received primary (including specialist homelessness health service based general practitioner care, mental health and addictions services) and secondary care. Main outcome measures were rates of: recruitment; retention; uptake of the intervention; and completeness of collected data, from recruitment to censor date.

RESULTS

Twenty four patients were offered and agreed to participate; 12 were reached and received the intervention as planned with a median 7.5 consultations (IQR3.0-14.2) per patient. The pharmacist prescribed a median of 2 new (IQR0.3-3.8) and 2 repeat (1.3-7.0) prescriptions per patient; 10(83%) received support for benefits, housing or advocacy. Twelve patients were not subsequently contactable after leaving hospital, despite agreeing to participate, and were assigned to UC. Two patients in the UC group died of drug/alcohol overdose during follow up; no patients in the Intervention group died. All 24 patients were retained in the intervention or UC group until death or censor date and all patient records were accessible at follow up: 11(92%) visited ED in both groups, with 11(92%) hospitalisations in intervention group, 9(75%) UC. Eight (67%) intervention group patients and 3(25%) UC patients attended scheduled out patient appointments.

CONCLUSIONS

Feasibility testing of the PHOENIx intervention suggests merit in a subsequent pilot RCT.

Patterns and effects of social integration on housing stability, mental health and substance use outcomes among participants in a randomized controlled Housing First trial

INTRODUCTION

Recent research has shown that social integration, involving community integration and social support, can be protective resources for the health of homeless individuals. However, it is not clear how social integration affects health in the transition from homelessness into housing, and subsequent housing retention. This paper examines, through mixed quantitative and qualitative methods, how social integration changes over time, and how these changes relate to housing stability, substance use and mental health outcomes among a sample of homeless individuals experiencing mental illness participating in the At Home/Chez Soi Housing First randomized controlled trial in Canada.

METHODS

Longitudinal quantitative data (baseline, 6, 12, 24 month) and qualitative data ( 18 month) from the five trial sites (Moncton, Montreal, Toronto, Winnipeg and Vancouver) were examined using mixed models, mediation analyses, and thematic analysis.

RESULTS

Social integration (i.e., social network size, social interest, psychological integration) increased over time among study participants, with social network size increasing significantly more among Housing First participants than Treatment as Usual participants. Social network size mediated the effect of the intervention on the percentage of days in stable housing, indicating that the Housing First intervention may have increased participants' social network size, which in turn increased the percentage of days stably housed. No significant mediation of social integration on the effects of the intervention on mental health and substance use outcomes was found. Findings from the qualitative interviews support and expand upon these quantitative findings.

Prevalence of Hoarding Behavior Among Formerly Homeless Persons Living in Supported Housing

Hoarding disorder has become an official disorder in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Hoarding disorder affects approximately 1.5% to 5% of the general population, and there is no known literature that has examined the prevalence of hoarding disorder among homeless populations or those living in supported housing, although hoarding problems can jeopardize their housing situation. This study used the Clutter Image Rating to estimate the prevalence of possible hoarding behavior among 660 adults living in supported housing. The results indicate that 18.5% of supported housing residents had hoarding behavior, which is more than three times the prevalence reported in the general population. These results suggest that hoarding behavior and possibly hoarding disorder may be more prevalent among those with histories of homelessness and housing instability, which may be of concern because it may affect both housing and health statuses.

Homeless Adults' Recovery Experiences in Housing First and Traditional Services Programs in Seven European Countries

Across Europe, as governments turn to housing-led strategies in attempts to reverse rising rates of homelessness, increasing numbers of Housing First (HF) programs are being implemented. As HF programs become more widespread, it is important to understand how service users experience them compared to the more prevalent traditional treatment-first approach to addressing long-term homelessness. Although there is a large body of research on service users' experiences of Housing First compared to treatment-first in North American contexts, comparatively less is known about how these two categories of homeless services are experienced in the European context. In a correlational and cross-sectional study, part of a larger examination of homelessness in Europe, participants (n = 520) engaged with either HF (n = 245) or traditional services (TS; n = 275) programs in seven countries completed measures of their experiences of services (consumer choice, housing quality, and service satisfaction) and recovery (time in independent housing, psychiatric symptoms, and community integration). Across the seven countries, participants engaged with HF programs reported experiencing more consumer choice, better perceived housing quality, and more satisfaction with services than participants engaged in TS programs. Participants in HF programs also reported a greater proportion of time in independent accommodation, fewer psychiatric symptoms, and more community integration. Varying patterns of association between experiences of services and recovery outcomes were observed. Findings indicate HF consistently predicts greater recovery than TS across diverse sociopolitical and economic contexts. Implications of findings for configurations of homeless services and homeless services policy are discussed.

Satisfaction with health and community services among homeless and formerly homeless individuals in Quebec, Canada

User satisfaction is a crucial quality indicator in health service provision. Few studies have measured user satisfaction among homeless and formerly homeless individuals, despite the high prevalence of mental health disorders (MHD) in this population. The purpose of this study was to assess overall satisfaction among 455 homeless and formerly homeless individuals who were receiving health and community services, and to identify factors associated with user satisfaction. Data collection occurred between January and September 2017. Study participants were 18 years old or over, with experience of homelessness in the current or recent past. They completed a questionnaire eliciting socio-demographic information, and data on residential history, service use and satisfaction and health profiles. Multivariate linear analysis was performed on overall satisfaction with health and community services in the previous 12 months. Independent variables were organised as predisposing, enabling and needs factors based on the Gelberg-Andersen Behavioral Model. The mean satisfaction score was 4.11 (minimum: 1; maximum: 5). Variables associated with greater user satisfaction included: older age, residence in permanent housing, common MHD (e.g., depression, anxiety), having a family physician, having a case manager, strong social network, good quality of life and, marginally, male sex and having substance use disorders (SUD). By contrast, frequent users of public ambulatory health services were the most dissatisfied. User satisfaction was more strongly associated with enabling factors. Strategies for improving satisfaction include: promoting more tailored primary care programmes (including family physician) adapted to the needs of this population, better integrating primary care with specialised services including SUD integrated treatment and enhancing continuity of care through the reinforcement of case management services. Further efforts aimed at increasing access to permanent housing with supports, and eliciting more active involvement by relatives and friends may also improve user satisfaction with services, and reduce unnecessary service use.

The Impact of Housing First on Criminal Justice Outcomes among Homeless People with Mental Illness: A Systematic Review

OBJECTIVE

Housing First is increasingly put forward as an important component of a pragmatic plan to end homelessness. The literature evaluating the impact of Housing First on criminal justice involvement has not yet been systematically examined. The objective of this systematic review is to examine the impact of Housing First on criminal justice outcomes among homeless people with mental illness.

METHOD

Five electronic databases (PsycINFO, MEDLINE, Embase, CINAHL, Web of Science) were searched up until July 2018 for randomised and nonrandomised studies of Housing First among homeless people with a serious mental disorder.

RESULTS

Five studies were included for a total of 7128 participants. Two studies from a randomised controlled trial found no effect of Housing First on arrests compared to treatment as usual. Other studies compared Housing First to other programs or compared configurations of HF and found reductions in criminal justice involvement among Housing First participants.

CONCLUSIONS

This systematic review suggests that Housing First, on average, has little impact on criminal justice involvement. Community services such as Housing First are potentially an important setting to put in place strategies to reduce criminal justice involvement. However, forensic mental health approaches such as risk assessment and management strategies and interventions may need to be integrated into existing services to better address potential underlying individual criminogenic risk factors. Further outcome assessment studies would be necessary.

Willingness to Use Safe Consumption Spaces among Opioid Users at High Risk of Fentanyl Overdose in Baltimore, Providence, and Boston

Safe consumption spaces (SCS) are evidence-based interventions that reduce drug-related morbidity and mortality operating in many countries. However, SCS are yet to be widely implemented in the USA despite the escalating overdose epidemic. The aim of this multi-city study was to identify the factors associated with willingness to use a SCS among people who use drugs (PWUD) in Baltimore, Providence, and Boston, stratified by injection drug use status. Our secondary aim was to characterize the anticipated barriers to accessing SCS if they were to be implemented in these cities. PWUD were invited to complete a cross-sectional survey in 2017. The analysis was restricted to 326 opioid users (i.e., heroin, fentanyl, and non-medical opioid pill use). The majority (77%) of participants expressed willingness to use a SCS (Baltimore, 78%; Providence, 68%; Boston. 84%). Most respondents were male (59%), older than 35 years (76%), non-white (64%), relied on public/semi-public settings to inject (60%), had a history of overdose (64%), and recently suspected fentanyl contamination of their drugs (73%). A quarter (26%) preferred drugs containing fentanyl. Among injectors, female gender, racial minority status, suspicion of drugs containing fentanyl, and drug use in public/semi-public settings were associated with higher willingness to use a SCS; prior arrest was associated with lower willingness. Among non-injectors, racial minority status, preference for fentanyl, and drug use in public/semi-public settings were associated with higher willingness, whereas recent overdose held a negative association. The most commonly anticipated barriers to accessing a SCS in the future were concerns around arrest (38%), privacy (34%), confidentiality/trust/safety (25%), and cost/time/transportation (16%). These data provide evidence of high SCS acceptability among high-risk PWUD in the USA, including those who prefer street fentanyl. As SCS are implemented in the USA, targeted engagement efforts may be required to reach individuals exposed to the criminal justice system.

Models of Housing in the Quebec Setting for Individuals With Mental Illness

The World Health Organization (WHO) defines mental health as "a state of well-being in which every individual realizes his or her own potential, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to her or his community". A person's mental health is shaped by various social, economic, physical, and environmental factors, at different stages of life. Risk factors are heavily associated with social inequalities in the domains of employment, housing, and education. Theories of social determinants of health postulate the beneficial effects of factors exterior to medicine (regarding income, housing, education, and employment) on the health of individuals and populations. Recognition of the effect of social determinants on the health of vulnerable populations has been at the core of the intervention models and housing services developed by social service professionals in Québec. This article offers a review of housing services provided to psychiatric patients living in the community, over the last 50 years in Quebec. Different models of housing with social support which contribute to the autonomy, the security, and the empowerment of psychiatric patients are presented.

Unpacking Clinical Supervision in Transitional and Permanent Supportive Housing: Scrutiny or Support?

Behavioral health organizations use clinical supervision to ensure professional development and practice quality. This qualitative study examined 35 service coordinators' perspectives on supervision in two distinct supportive housing program types (permanent and transitional). Thematic analysis of in-depth interviews yielded three contrast themes: support versus scrutiny, planned versus impromptu time, and housing first versus treatment first. Supervisory content and format resulted in differential perceptions of supervision, thereby influencing opportunities for learning. These findings suggest that unpacking discrete elements of supervision enactment in usual care settings can inform implementation of recovery-oriented practice.

Independent housing and support for people with severe mental illness: systematic review

OBJECTIVE

To systematically explore the outcomes of Independent Housing and Support (IHS) for people with severe mental disorders when compared to other residential settings.

METHOD

Systematic review of Randomised and Non-Randomised Controlled Trials of publications that analyse the outcomes of living in independent settings versus institutionalised accommodation. Risk of bias assessment was adapted from the Cochrane Collaboration's ACROBAT-Tool. The analysis was conducted separately for publications with homeless and non-homeless people.

RESULTS

Twenty-four publications from studies with homeless people and eight publications from studies with non-homeless people were included. Risk of bias was much lower in studies with the homeless. No RCT was found in the sample of publications with the non-homeless. Overall, results from Independent Housing and Support-settings are not inferior to results from institutionalised settings.

CONCLUSION

The results indicate that Independent Housing and Support-settings provide at least similar outcomes than residential care. We propose that clients' preferences should determine the choice of housing setting.

Housing First for Adults with Problematic Substance Use

OBJECTIVES

This study explores the two-year housing- and non-housing-related outcomes for adults who are homeless with problematic substance use who received scattered-site housing and intensive case management services from a Housing First program in Ottawa, Canada, in comparison with a group of adults who are homeless with problematic substance use who had access to standard care in the community.

METHODS

Housing First clients (n = 89) and members of a comparison group (n = 89) completed structured interviews at baseline and were followed for two years.

RESULTS

Housing First clients moved into housing more quickly, reported a greater proportion of time housed, were more likely to spend the final six months housed, and had longer housing tenure at 24 months. There was a group by time interaction on problematic alcohol use with more rapid improvement for the comparison group; however, both groups improved over time. The comparison group had a greater decrease on problematic drug use by 24 months. There was no change in physical health and only the comparison group had improvements in mental health by 24 months. The groups had similar improvement on community functioning by 24 months. The comparison group had a greater increase in total quality of life. More specifically, the comparison group had an increase in the family relations-related quality of life, whereas the clients did not. There was a significant interaction for safety-related quality of life, but both groups experienced improvements over time and had comparable levels of satisfaction with safety at each time point. The Housing First clients reported higher levels of satisfaction with living conditions than the comparison group at baseline and 12 months, but not at 24 months. There was significant improvement over time and no main effect of group for finances, leisure, and social relations.

CONCLUSIONS

Adults who are homeless with problematic substance use can successfully be housed using a Housing First approach. However, further targeted services might be required to address other areas of functioning, such as health, substance use, and quality of life.

Food security among individuals experiencing homelessness and mental illness in the At Home/Chez Soi Trial

OBJECTIVE

Individuals experiencing homelessness are particularly vulnerable to food insecurity. The At Home/Chez Soi study provides a unique opportunity to first examine baseline levels of food security among homeless individuals with mental illness and second to evaluate the effect of a Housing First (HF) intervention on food security in this population.

DESIGN

At Home/Chez Soi was a 2-year randomized controlled trial comparing the effectiveness of HF compared with usual care among homeless adults with mental illness, stratified by level of need for mental health services (high or moderate). Logistic regressions tested baseline associations between food security (US Food Security Survey Module), study site, sociodemographic variables, duration of homelessness, alcohol/substance use, physical health and service utilization. Negative binomial regression determined the impact of the HF intervention on achieving levels of high or marginal food security over an 18-month follow-up period (6 to 24 months).

SETTING

Community settings at five Canadian sites (Moncton, Montreal, Toronto, Winnipeg and Vancouver).

SUBJECTS

Homeless adults with mental illness (n 2148).

RESULTS

Approximately 41 % of our sample reported high or marginal food security at baseline, but this figure varied with gender, age, mental health issues and substance use problems. High need participants who received HF were more likely to achieve marginal or high food security than those receiving usual care, but only at the Toronto and Moncton sites.

CONCLUSIONS

Our large multi-site study demonstrated low levels of food security among homeless experiencing mental illness. HF showed promise for improving food security among participants with high levels of need for mental health services, with notable site differences.

Housing First and harm reduction: a rapid review and document analysis of the US and Canadian open-access literature

BACKGROUND

Housing First is an evidence-based practice intended to serve chronically homeless individuals with co-occurring serious mental illness and substance use disorders. Despite housing active substance users, harm reduction is an often-overlooked element during the Housing First implementation process in real-world settings. In this paper, we explore the representation of the Housing First model within the open-access scholarly literature as a potential contributing factor for this oversight.

METHODS

We conducted a rapid review of the US and Canadian open-access Housing First literature. We followed a document analysis approach, to form an interpretation of the articles' content related to our primary research questions.

RESULTS

A total of 55 articles on Housing First were included in the final analysis. Only 21 of these articles (38.1%) included explicit mention of harm reduction. Of the 34 articles that did not discuss harm reduction, 22 provided a description of the Housing First model indicating it does not require abstinence from substance use; however, descriptions did not all clearly indicate abstinence was not required beyond program entry. Additional Housing First descriptions focused on the low-barrier entry criteria and/or the intervention's client-centeredness.

CONCLUSIONS

Our review demonstrated a lack of both explicit mention and informed discussion of harm reduction in the Housing First literature, which is likely contributing to the Housing First research-practice gap to some degree. Future Housing First literature should accurately explain the role of harm reduction when discussing it in the context of Housing First programming, and public agencies promoting Housing First uptake should provide resources for proper implementation and monitor program fidelity to prevent model drift.

Factors Affecting Emergency Department Use by a Chronically Homeless Population

OBJECTIVE

Homeless adults make extensive use of emergency department (ED) services. This study examined factors associated with moderate and high ED use in a cohort of chronically homeless individuals.

METHODS

A cross-sectional analysis identified factors related to ED use in a cohort of 755 individuals at 11 sites at entry into the Collaborative Initiative to Help End Chronic Homelessness (CICH). Bivariate analyses identified sociodemographic, housing status, health status, and service-related factors associated with moderate and high ED use. Independent risk factors were then identified by using a multivariate multinomial model. Hierarchical regression was used to compare the strengths of association between ED use and blocks of factors composed of sociodemographic, housing, health, and service-related characteristics.

RESULTS

In a three-month period, 30% of participants visited the ED one or two times (moderate ED use) and 12% visited three or more times (high-ED use). ED use was most strongly associated with poor health and utilization of other non-ED services and to a lesser extent with housing status.

CONCLUSIONS

Increased ED utilization was associated with both general medical and psychiatric morbidity and greater use of non-ED services. Thus ED use was related to high need and acuity and was not ameliorated by use of other services. Housing instability and homelessness contributed less robustly to increased ED use. More coordinated services may better address the complex medical, housing, and psychosocial needs of chronically homeless individuals.

Emergency department use and hospitalizations among homeless adults with substance dependence and mental disorders

Background

Homelessness, substance use, and mental disorders each have been associated with higher rates of emergency department (ED) use and hospitalization. We sought to understand the correlation between ED use, hospital admission, and substance dependence among homeless individuals with concurrent mental illness who participated in a ‘Housing First’ (HF) intervention trial.

Methods

The Vancouver At Home study consisted of two randomized controlled trials addressing homeless individuals with mental disorders who have “high” or “moderate” levels of need. Substance dependence was determined at baseline prior to randomization, using the Mini International Neuropsychiatric Interview diagnostic tool, version 6.0. To assess health service use, we reviewed the number of ED visits and the number of hospital admissions based on administrative data for six urban hospitals. Negative binomial regression modeling was used to test the independent association between substance dependence and health service use (ED use and hospitalization), adjusting for HF intervention, age, gender, ethnicity, education, duration of lifetime homelessness, mental disorders, chronic health conditions, and other variables that were selected a priori to be potentially associated with use of ED services and hospital admission.

Results

Of the 497 homeless adults with mental disorders who were recruited, we included 381 participants in our analyses who had at least 1 year of follow-up and had a personal health number that could be linked to administrative health data. Of this group, 59% (n = 223) met criteria for substance dependence. We found no independent association between substance dependence and ED visits or hospital admissions [rate ratio (RR) = 0.85; 95% CI 0.62–1.17 and RR = 1.21; 95% CI 0.83–1.77, respectively]. The most responsible diagnoses (defined as the diagnosis that accounts for the length of stay) for hospital admissions were schizo-affective disorder, schizophrenia-related disorder, or bipolar affective disorder; collectively reported in 48% (n = 263) of admissions. Fifteen percent (n = 84) of hospital admissions listed substance dependence as the most responsible diagnosis.

Conclusions

Substance dependence was not independently associated with ED use or hospital admission among homeless adults with mental disorders participating in an HF trial. Hospital admissions among this cohort were primarily associated with severe mental disorders.

The impact of a Housing First randomized controlled trial on substance use problems among homeless individuals with mental illness

BACKGROUND

There is strong evidence that Housing First interventions are effective in improving housing stability and quality of life among homeless people with mental illness and addictions. However, there is very little evidence on the effectiveness of Housing First in improving substance use-related outcomes in this population. This study uses a randomized control design to examine the effects of scatter-site Housing First on substance use outcomes in a large urban centre.

METHODS

Substance use outcomes were compared between a Housing First intervention and treatment as usual group in a sample of 575 individuals experiencing homelessness and mental illness, with or without a co-occurring substance use problem, in the At Home/Chez Soi trial in Toronto, Canada. Generalized linear models were used to compare study arms with respect to change in substance use outcomes over time (baseline, 6, 12, 18 and 24 month).

RESULTS

At 24 months, participants in the Housing First intervention had significantly greater reductions in number of days experiencing alcohol problems and amount of money spent on alcohol than participants in the Treatment as Usual group. No differences between the study arms in illicit drug outcomes were found at 24 months.

CONCLUSIONS

These findings show that a Housing First intervention can contribute to reductions in alcohol problems over time. However, the lack of effect of the intervention on illicit drug problems suggests that individuals experiencing homelessness, mental illness and drug problems may need additional supports to reduce use.

Accessibility patterns and community integration among previously homeless adults: a Geographic Information Systems (GIS) approach

Although a desired rehabilitation goal, research continues to document that community integration significantly lags behind housing stability success rates for people of a variety of ages who used to be homeless. While accessibility to resources is an environmental factor that may promote or impede integration activity, there has been little empirical investigation into the impact of proximity of community features on resource use and integration. Using a Geographic Information Systems (GIS) approach, the current study examines how accessibility or proximity to community features in Boston, United States related to the types of locations used and the size of an individual's "activity space," or spatial presence in the community. Significant findings include an inverse relationship between activity space size and proximity to the number and type of community features in one's immediate area. Specifically, larger activity spaces were associated with neighborhoods with less community features, and smaller activity spaces corresponded with greater availability of resources within one's immediate area. Activity space size also varied, however, based on proximity to different types of resources, namely transportation and health care. Greater community function, or the ability to navigate and use community resources, was associated with better accessibility and feeling part of the community. Finally, proximity to a greater number of individual identified preferred community features was associated with better social integration. The current study suggests the ongoing challenges of successful integration may vary not just based on accessibility to, but relative importance of, specific community features and affinity with one's surroundings. Community integration researchers and housing providers may need to attend to the meaning attached to resources, not just presence or use in the community.

Measuring community integration using Geographic Information Systems (GIS) and participatory mapping for people who were once homeless

Measures of community integration rely on self-report assessments that often quantify physical or social participation, but fail to capture the individual׳s spatial presence in the community. The current study documents the activity space, or area of daily experiences, of 37 individuals who were once homeless through participatory mapping and Geographic Information Systems (GIS). Contrary to expectations, there was no significant relationship between activity space size and community integration measures, except a negative association with physical integration. Further analysis revealed, however, that continued use of homeless services, geographically spread throughout the city, was associated with larger activity space size, but may be counterproductive to social and psychological integration efforts. Analysis of the types of locations identified revealed high importance given to leisure locations and ongoing involvement with medical and mental health locations. Finally, community integration outcomes did not differ significantly by demographics or housing type, but rather degree of family involvement and feeling like home, factors that may have more potential for change.

Housing first improves residential stability in homeless adults with concurrent substance dependence and mental disorders

OBJECTIVES

We examined the relationship between substance dependence and residential stability in homeless adults with current mental disorders 12 months after randomization to Housing First programs or treatment as usual (no housing or support through the study).

METHODS

The Vancouver At Home study in Canada included 2 randomized controlled trials of Housing First interventions. Eligible participants met the criteria for homelessness or precarious housing, as well as a current mental disorder. Residential stability was defined as the number of days in stable residences 12 months after randomization. We used negative binomial regression modeling to examine the independent association between residential stability and substance dependence.

RESULTS

We recruited 497 participants, and 58% (n = 288) met the criteria for substance dependence. We found no significant association between substance dependence and residential stability (adjusted incidence rate ratio = 0.97; 95% confidence interval = 0.69, 1.35) after adjusting for housing intervention, employment, sociodemographics, chronic health conditions, mental disorder severity, psychiatric symptoms, and lifetime duration of homelessness.

CONCLUSIONS

People with mental disorders might achieve similar levels of housing stability from Housing First regardless of whether they experience concurrent substance dependence.
