A critical time intervention with mentally ill homeless men: impact on psychiatric symptoms

Outcomes of psychosocial interventions for homeless individuals with mental illness: A systematic review

BACKGROUND

Homelessness creates a significant social and economic burden in the society. Homelessness and mental illness are two interconnected social issues that poses challenges to individuals and communities across the globe. This systematic review aims to synthesize the existing literature on interventions for the homeless persons with mental illness.

OBJECTIVES

To systematically review the existing literature on psychosocial interventions for homeless persons with mental illness.

SEARCH METHODS

Five databases including PubMed, ProQuest, Cochrane Library, OVID, and Google Scholar were searched using homelessness, psychosocial interventions, mental ill, residential mental health facility, and case management for experimental studies published from January 2000 to December 2022.

STUDY SELECTION

Abstract review was conducted for the screened studies, and full-text review was done for studies which met inclusion exclusion criteria.

DATA EXTRACTION AND ANALYSIS

Among the 6,387 studies screened 20 studies were selected which fulfilled inclusion criteria. The full text review yielded data of 12,174 homeless persons with mental illness who undergone intervention.

RESULTS

The major psychosocial interventions found including critical time intervention, case management, housing support intervention, assertive community treatment, and life skills training. These interventions were helpful in sustaining housing stability, preventing relapse, reducing hospitalizations, and improving quality of life of the homeless persons with mental illness.

CONCLUSION

Targeted and integrated interventions addressing homelessness and mental illness are required to tackle the social problems of homelessness and mental illness. Further research is required to explore the most effective strategies that address homelessness and mental illness.

Evaluating Intensity, Complexity, and Potential for Causal Inference in Social Needs Interventions: A Review of a Scoping Review

Importance

Interventions that address needs such as low income, housing instability, and safety are increasingly appearing in the health care sector as part of multifaceted efforts to improve health and health equity, but evidence relevant to scaling these social needs interventions is limited.

Objective

To summarize the intensity and complexity of social needs interventions included in randomized clinical trials (RCTs) and assess whether these RCTs were designed to measure the causal effects of intervention components on behavioral, health, or health care utilization outcomes.

Evidence Review

This review of a scoping review was based on a Patient-Centered Outcomes Research Institute-funded evidence map of English-language US-based RCTs of social needs interventions published between January 1, 1995, and April 6, 2023. Studies were assessed for features related to intensity (defined using modal values as providing as-needed interaction, 8 participant contacts or more, contacts occurring every 2 weeks or more often, encounters of 30 minutes or longer, contacts over 6 months or longer, or home visits), complexity (defined as addressing multiple social needs, having dedicated staff, involving multiple intervention components or practitioners, aiming to change multiple participant behaviors [knowledge, action, or practice], requiring or providing resources or active assistance with resources, and permitting tailoring), and the ability to assess causal inferences of components (assessing interventions, comparators, and context).

Findings

This review of a scoping review of social needs interventions identified 77 RCTs in 93 publications with a total of 135 690 participants. Most articles (68 RCTs [88%]) reported 1 or more features of high intensity. All studies reported 1 or more features indicative of high complexity. Because most studies compared usual care with multicomponent interventions that were moderately or highly dependent on context and individual factors, their designs permitted causal inferences about overall effectiveness but not about individual components.

Conclusions and Relevance

Social needs interventions are complex, intense, and include multiple components. Our findings suggest that RCTs of these interventions address overall intervention effectiveness but are rarely designed to distinguish the causal effects of specific components despite being resource intensive. Future studies with hybrid effectiveness-implementation and sequential designs, and more standardized reporting of intervention intensity and complexity could help stakeholders assess the return on investment of these interventions.

Assessing longitudinal housing status using Electronic Health Record data: a comparison of natural language processing, structured data, and patient-reported history

Introduction

Measuring long-term housing outcomes is important for evaluating the impacts of services for individuals with homeless experience. However, assessing long-term housing status using traditional methods is challenging. The Veterans Affairs (VA) Electronic Health Record (EHR) provides detailed data for a large population of patients with homeless experiences and contains several indicators of housing instability, including structured data elements (e.g., diagnosis codes) and free-text clinical narratives. However, the validity of each of these data elements for measuring housing stability over time is not well-studied.

Methods

We compared VA EHR indicators of housing instability, including information extracted from clinical notes using natural language processing (NLP), with patient-reported housing outcomes in a cohort of homeless-experienced Veterans.

Results

NLP achieved higher sensitivity and specificity than standard diagnosis codes for detecting episodes of unstable housing. Other structured data elements in the VA EHR showed promising performance, particularly when combined with NLP.

Discussion

Evaluation efforts and research studies assessing longitudinal housing outcomes should incorporate multiple data sources of documentation to achieve optimal performance.

Study protocol for a multisite randomized controlled trial of a peer navigator intervention for emergency department patients with nonfatal opioid overdose

BACKGROUND

Patients presenting to emergency departments (EDs) after a nonfatal opioid-involved overdose are at high risk for future overdose and death. Responding to this risk, the New York City (NYC) Department of Health and Mental Hygiene operates the Relay initiative, which dispatches trained peer "Wellness Advocates" to meet patients in the ED after a suspected opioid-involved overdose and follow them for up to 90 days to provide support, education, referrals to treatment, and other resources using a harm reduction framework.

METHODS

In this article, we describe the protocol for a multisite randomized controlled trial of Relay. Study participants are recruited from four NYC EDs and are randomized to receive the Relay intervention or site-directed care (the control arm). Outcomes are assessed through survey questionnaires conducted at 1-, 3-, and 6-months after the baseline visit, as well as through administrative health data. The primary outcome is the number of opioid-related adverse events, including any opioid-involved overdose or any other substance use-related ED visit, in the 12 months post-baseline. Secondary and exploratory outcomes will also be analyzed, as well as hypothesized mediators and moderators of Relay program effectiveness.

CONCLUSION

We present the protocol for a multisite randomized controlled trial of a peer-delivered OD prevention intervention in EDs. We describe how the study was designed to minimize disruption to routine ED operations, and how the study was implemented and adapted during the COVID-19 pandemic. This trial is registered with ClinicalTrials.gov [NCT04317053].

Racial Health Equity and Social Needs Interventions: A Review of a Scoping Review

Importance

Social needs interventions aim to improve health outcomes and mitigate inequities by addressing health-related social needs, such as lack of transportation or food insecurity. However, it is not clear whether these studies are reducing racial or ethnic inequities.

Objective

To understand how studies of interventions addressing social needs among multiracial or multiethnic populations conceptualize and analyze differential intervention outcomes by race or ethnicity.

Evidence Review

Sources included a scoping review of systematic searches of PubMed and the Cochrane Library from January 1, 1995, through November 29, 2021, expert suggestions, and hand searches of key citations. Eligible studies evaluated interventions addressing social needs; reported behavioral, health, or utilization outcomes or harms; and were conducted in multiracial or multiethnic populations. Two reviewers independently assessed titles, abstracts, and full text for inclusion. The team developed a framework to assess whether the study was "conceptually thoughtful" for understanding root causes of racial health inequities (ie, noted that race or ethnicity are markers of exposure to racism) and whether analyses were "analytically informative" for advancing racial health equity research (ie, examined differential intervention impacts by race or ethnicity).

Findings

Of 152 studies conducted in multiracial or multiethnic populations, 44 studies included race or ethnicity in their analyses; of these, only 4 (9%) were conceptually thoughtful. Twenty-one studies (14%) were analytically informative. Seven of 21 analytically informative studies reported differences in outcomes by race or ethnicity, whereas 14 found no differences. Among the 7 that found differential outcomes, 4 found the interventions were associated with improved outcomes for minoritized racial or ethnic populations or reduced inequities between minoritized and White populations. No studies were powered to detect differences.

Conclusions and Relevance

In this review of a scoping review, studies of social needs interventions in multiracial or multiethnic populations were rarely conceptually thoughtful for understanding root causes of racial health inequities and infrequently conducted informative analyses on intervention effectiveness by race or ethnicity. Future work should use a theoretically sound conceptualization of how race (as a proxy for racism) affects social drivers of health and use this understanding to ensure social needs interventions benefit minoritized racial and ethnic groups facing social and structural barriers to health.

Supporting Vulnerable People During Challenging Transitions: A Systematic Review of Critical Time Intervention

Critical Time Intervention (CTI) is designed to reduce the risk of homelessness and other adverse outcomes by providing support to individuals during challenging life course transitions. While several narrative reviews suggest the benefit of CTI, the evidence on the model's effectiveness has not been systematically reviewed. This article systematically reviews studies of CTI applied to a variety of populations and transition types. Following the Preferred Reporting Items for Systematic Review and Meta-Analysis for protocols (PRISMA-P) guidelines, we reviewed 13 eligible experimental and quasi-experimental studies. Findings were summarized by individual outcome domains, including housing, service engagement use, hospitalization or emergency services, mental health, substance use, family and social support, and quality of life. CTI had a consistent positive impact on two primary outcomes-reduced homelessness and increased service engagement use-among different populations and contexts. Despite the effectiveness of CTI, the specific mechanisms of the model's positive impacts remain unclear. Implications for practice, policy and research are addressed.

Engaging stakeholders to inform national implementation of critical time intervention in a program serving homeless-experienced Veterans

The Veterans Affairs (VA) Grant and Per Diem Case Management "Aftercare" program provides 6 months of case management for homeless-experienced Veterans (HEVs) transitioning to permanent housing, with the aim of decreasing returns to homelessness. Implementing Critical Time Intervention (CTI)-an evidence-based case management practice-would standardize care across the 128 community-based agencies that provide Aftercare services. To prepare for national CTI implementation in Aftercare, guided by Replicating Effective Programs (REP), we conducted a four-site pilot in which we adapted a CTI implementation package (training, technical assistance, and external facilitation); characterized stakeholder perspectives regarding the acceptability and appropriateness of this package; and identified contextual factors that affected CTI implementation. We engaged a stakeholder workgroup to tailor existing CTI training and technical assistance materials for Aftercare. To provide tailored support for providers and leaders to adopt and incorporate evidence-based practices (EBPs) into routine care, we also developed external facilitation materials and processes. Over 9 months, we implemented this package at four sites. We conducted semi-structured interviews at pre-implementation, mid-implementation, and 6 months post-implementation, with HEVs (n = 37), case managers (n = 16), supervisors (n = 10), and VA leaders (n = 4); these data were integrated with templated reflection notes from the project facilitator. We used rapid qualitative analysis and targeted coding to assess the acceptability and appropriateness of CTI and our implementation package and identify factors influencing CTI implementation. Stakeholders generally found CTI acceptable and appropriate; there was consensus that components of CTI were useful and compatible for this setting. To adapt our implementation package for scale-up, this pilot highlighted the value of robust and tangible CTI training and technical assistance-grounded in real-world cases-that highlights the congruence of CTI with relevant performance metrics. Variations in agency-level contextual factors may necessitate more intense and tailored supports to implement and sustain complex EBPs like CTI. Processes used in this pilot are relevant for implementing other EBPs in organizations that serve vulnerable populations. EBP scale-up and sustainment can be enhanced by engaging stakeholders to tailor EBPs for specific contexts; pilot testing and refining implementation packages for scale-up; and using qualitative methods to characterize contextual factors that affect EBP implementation.

Comparing two implementation strategies for implementing and sustaining a case management practice serving homeless-experienced veterans: a protocol for a type 3 hybrid cluster-randomized trial

Background

The Veterans Health Administration (VA) Grant and Per Diem case management “aftercare” program provides 6 months of case management for homeless-experienced veterans (HEVs) undergoing housing transitions. To standardize and improve aftercare services, we will implement critical time intervention (CTI), an evidence-based, structured, and time-limited case management practice. We will use two strategies to support the implementation and sustainment of CTI at 32 aftercare sites, conduct a mixed-methods evaluation of this implementation initiative, and generate a business case analysis and implementation playbook to support the continued spread and sustainment of CTI in aftercare.

Methods

We will use the Replicating Effective Programs (REP) implementation strategy to support CTI implementation at 32 sites selected by our partners. Half (n=16) of these sites will also receive 9 months of external facilitation (EF, enhanced REP). We will conduct a type 3 hybrid cluster-randomized trial to compare the impacts of REP versus enhanced REP. We will cluster potential sites into three implementation cohorts staggered in 9-month intervals. Within each cohort, we will use permuted block randomization to balance key site characteristics among sites receiving REP versus enhanced REP; sites will not be blinded to their assigned strategy. We will use mixed methods to assess the impacts of the implementation strategies. As fidelity to CTI influences its effectiveness, fidelity to CTI is our primary outcome, followed by sustainment, quality metrics, and costs. We hypothesize that enhanced REP will have higher costs than REP alone, but will result in stronger CTI fidelity, sustainment, and quality metrics, leading to a business case for enhanced REP. This work will lead to products that will support our partners in spreading and sustaining CTI in aftercare.

Discussion

Implementing CTI within aftercare holds the potential to enhance HEVs’ housing and health outcomes. Understanding effective strategies to support CTI implementation could assist with a larger CTI roll-out within aftercare and support the implementation of other case management practices within and outside VA.

Health professionals' experience of implementing and delivering a 'Community Care' programme in metropolitan Melbourne: a qualitative reflexive thematic analysis

OBJECTIVES

To explore the experiences of health professionals involved in delivering a multidisciplinary Community Care programme that provides a transitional care coordination service for patients visiting a tertiary hospital service in Melbourne, Australia.

DESIGN

Reflexive thematic analysis was used to identify themes from descriptions of delivering the programme, including its perceived strengths and challenges.

PARTICIPANTS

12 healthcare professionals from four disciplines working in the Community Care programme were interviewed.

RESULTS

Four themes were identified: (1) 'increasingly complex', depicts the experience of delivering care to patients with increasingly complex health needs; (2) 'plugging unexpected gaps', describes meeting patient's healthcare needs; (3) 'disconnected', explains system-based issues which made participants feel disconnected from the wider health service; (4) 'a misunderstood programme', illustrates that a poor understanding of the programme within the health service is a barrier to patient enrolment which may have been exacerbated by a service name change.

CONCLUSIONS

The healthcare professionals involved in this study described the experience of providing care to patients as challenging, but felt they made a positive difference. By unravelling the patients' health problems in context of their surroundings, they were able to recognise the increasingly complex patients' health needs. The disconnection they faced to integrate within the wider healthcare system made their role at times difficult. This disconnection was partly contributed to by the fact that they felt the programme was misunderstood.

The prevalence of mental disorders among homeless people in high-income countries: An updated systematic review and meta-regression analysis

BACKGROUND

Homelessness continues to be a pressing public health concern in many countries, and mental disorders in homeless persons contribute to their high rates of morbidity and mortality. Many primary studies have estimated prevalence rates for mental disorders in homeless individuals. We conducted a systematic review and meta-analysis of studies on the prevalence of any mental disorder and major psychiatric diagnoses in clearly defined homeless populations in any high-income country.

METHODS AND FINDINGS

We systematically searched for observational studies that estimated prevalence rates of mental disorders in samples of homeless individuals, using Medline, Embase, PsycInfo, and Google Scholar. We updated a previous systematic review and meta-analysis conducted in 2007, and searched until 1 April 2021. Studies were included if they sampled exclusively homeless persons, diagnosed mental disorders by standardized criteria using validated methods, provided point or up to 12-month prevalence rates, and were conducted in high-income countries. We identified 39 publications with a total of 8,049 participants. Study quality was assessed using the JBI critical appraisal tool for prevalence studies and a risk of bias tool. Random effects meta-analyses of prevalence rates were conducted, and heterogeneity was assessed by meta-regression analyses. The mean prevalence of any current mental disorder was estimated at 76.2% (95% CI 64.0% to 86.6%). The most common diagnostic categories were alcohol use disorders, at 36.7% (95% CI 27.7% to 46.2%), and drug use disorders, at 21.7% (95% CI 13.1% to 31.7%), followed by schizophrenia spectrum disorders (12.4% [95% CI 9.5% to 15.7%]) and major depression (12.6% [95% CI 8.0% to 18.2%]). We found substantial heterogeneity in prevalence rates between studies, which was partially explained by sampling method, study location, and the sex distribution of participants. Limitations included lack of information on certain subpopulations (e.g., women and immigrants) and unmet healthcare needs.

CONCLUSIONS

Public health and policy interventions to improve the health of homeless persons should consider the pattern and extent of psychiatric morbidity. Our findings suggest that the burden of psychiatric morbidity in homeless persons is substantial, and should lead to regular reviews of how healthcare services assess, treat, and follow up homeless people. The high burden of substance use disorders and schizophrenia spectrum disorders need particular attention in service development. This systematic review and meta-analysis has been registered with PROSPERO (CRD42018085216).

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.

"En la Lucha": Strategies to Improve HIV Care for Puerto Ricans with Opioids Use Disorders

BACKGROUND

Clínica Bienestar is a comprehensive HIV primary care clinic for Spanish-speaking Latinx with opioids use disorders (OUD). This article describes the barriers and trajectories to HIV viral suppression for Puerto Ricans with a transnational profile and dual diagnoses (HIV and OUD), and the strategies applied to increase retention in care.

METHODS

Case study methodology was used to select two patient life histories that illustrate the most common pathways to success in reducing HIV viral load to undetectable and achieving OUD long-term recovery.

RESULTS AND DISCUSSION

Patients' major challenges included: (1) Persistent migrating while seeking substance use treatment services with limited or no support from their sending and hosting communities; (2) Intersectional stigmas; (3) Untreated trauma; (4) Language and cultural barriers. Clínica Bienestar's service model included ten strategies to retain patients in care (e.g., Case management to identify cases with high social isolation), six emerged as central to addressing transnational challenges.

The effectiveness of case management interventions for the homeless, vulnerably housed and persons with lived experience: A systematic review

BACKGROUND

Individuals who are homeless or vulnerably housed are at an increased risk for mental illness, other morbidities and premature death. Standard case management interventions as well as more intensive models with practitioner support, such as assertive community treatment, critical time interventions, and intensive case management, may improve healthcare navigation and outcomes. However, the definitions of these models as well as the fidelity and adaptations in real world interventions are highly variable. We conducted a systematic review to examine the effectiveness and cost-effectiveness of case management interventions on health and social outcomes for homeless populations.

METHODS AND FINDINGS

We searched Medline, Embase and 7 other electronic databases for trials on case management or care coordination, from the inception of these databases to July 2019. We sought outcomes on housing stability, mental health, quality of life, substance use, hospitalization, income and employment, and cost-effectiveness. We calculated pooled random effects estimates and assessed the certainty of the evidence using the GRADE approach. Our search identified 13,811 citations; and 56 primary studies met our full inclusion criteria. Standard case management had both limited and short-term effects on substance use and housing outcomes and showed potential to increase hostility and depression. Intensive case management substantially reduced the number of days spent homeless (SMD -0.22 95% CI -0.40 to -0.03), as well as substance and alcohol use. Critical time interventions and assertive community treatment were found to have a protective effect in terms of rehospitalizations and a promising effect on housing stability. Assertive community treatment was found to be cost-effective compared to standard case management.

CONCLUSIONS

Case management approaches were found to improve some if not all of the health and social outcomes that were examined in this study. The important factors were likely delivery intensity, the number and type of caseloads, hospital versus community programs and varying levels of participant needs. More research is needed to fully understand how to continue to obtain the increased benefits inherent in intensive case management, even in community settings where feasibility considerations lead to larger caseloads and less-intensive follow-up.

Specialized assertive community treatment intervention for homeless youth with first episode psychosis and substance use disorder: A 2-year follow-up study

AIM

No previous study has investigated interventions for homeless youth suffering from first episode psychosis and comorbid substance use disorder (HYPS). An intensive assertive community intervention team (IACIT) offering outreach interventions, housing support as well as integrated care for early psychosis and substance use disorder (SUD) was created in 2012 at the Centre Hospitalier de l'Université de Montréal (CHUM). To explore the impact of the addition of an IACIT to an early intervention for psychosis service (EIS) on housing stability, functional and symptomatic outcomes and mental health service use.

METHODS

A two-year longitudinal study comparing the outcome of HYPS receiving combined EIS and IACIT since 2012, to a historical cohort of HYPS receiving EIS only between 2005 and 2011. Socio-demographic data, housing stability, functioning, illness severity, SUD severity, emergency room visits and hospitalizations were assessed at admission, at 1 month, and every 3 months thereafter.

RESULTS

HYPS receiving EIS + IACIT achieved housing stability more rapidly and spent less time hospitalized than HYPS getting EIS only (RR 2.38, P = .017). HYPS with cocaine misuse were less likely to attain housing stability (RR 0.25, P = .04). No between-group differences were found for psychiatric symptoms, functioning and SUD outcomes.

CONCLUSION

The addition of IACIT-HYPS to EIS was associated with earlier housing stability and reduced total hospitalization days compared to EIS alone.

Bridging Hospital and Community Care for Homeless Adults with Mental Health Needs: Outcomes of a Brief Interdisciplinary Intervention

OBJECTIVE

This study examines health and service use outcomes and associated factors among homeless adults participating in a brief interdisciplinary intervention following discharge from hospital.

METHOD

Using a pre-post cohort design, 223 homeless adults with mental health needs were enrolled in the Coordinated Access to Care for the Homeless (CATCH) program, a 4- to 6-month interdisciplinary intervention offering case management, peer support, access to primary psychiatric care, and supplementary community services. Study participants were interviewed at program entry and at 3- and 6-month follow-up visits and assessed for health status, acute care service use, housing outcomes, mental health, substance use, quality of life, and their working alliance with service providers. Linear mixed models and generalized estimating equations were performed to examine outcomes longitudinally. Additional post hoc analyses evaluated differences between CATCH participants and a comparison group of homeless adults experiencing mental illness who received usual services over the same period.

RESULTS

In the pre-post analyses, CATCH participants had statistically significant improvements in mental and physical health status and reductions in mental health symptoms, substance misuse, and the number of hospital admissions. The strength of the working alliance between participants and their case manager was associated with reduced health care use and mental health symptoms. Post hoc analyses suggest that CATCH may be associated with statistically significant improvements in mental health symptoms in the study population.

CONCLUSIONS

A brief interdisciplinary intervention may be a promising approach to improving health outcomes among homeless adults with unmet health needs. Further rigorous research is needed into the effectiveness of brief interventions following discharge from hospital.

Effectiveness of interventions to reduce homelessness: a systematic review and meta-analysis

This Campbell systematic review examines the effectiveness of interventions to reduce homelessness and increase residential stability for individuals who are homeless, or at risk of becoming homeless. Forty-three studies were included in the review, 37 of which are from the USA. Included interventions perform better than the usual services at reducing homelessness or improving housing stability in all comparisons. These interventions are: High intensity case managementHousing FirstCritical time interventionAbstinence-contingent housingNon-abstinence-contingent housing with high intensity case managementHousing vouchersResidential treatment These interventions seem to have similar beneficial effects, so it is unclear which of these is best with respect to reducing homelessness and increasing housing stability.

Plain Language Summary

Interventions to reduce homelessness and improve housing stability are effective: There are large numbers of homeless people around the world. Interventions to address homelessness seem to be effective, though better quality evidence is required.What is this review about?: There are large numbers of homeless people around the world. Recent estimates are over 500,000 people in the USA, 100,000 in Australia and 30,000 in Sweden. Efforts to combat homelessness have been made on national levels as well as at local government levels.This review assesses the effectiveness of interventions combining housing and case management as a means to reduce homelessness and increase residential stability for individuals who are homeless, or at risk of becoming homeless.What studies are included?: Included studies were randomized controlled trials of interventions for individuals who were already, or at-risk of becoming, homeless, and which measured impact on homelessness or housing stability with follow-up of at least one year.A total of 43 studies were included. The majority of the studies (37) were conducted in the United States, with three from the United Kingdom and one each from Australia, Canada, and Denmark.What are the main findings of this review?: Included interventions perform better than the usual services at reducing homelessness or improving housing stability in all comparisons. These interventions are: High intensity case managementHousing FirstCritical time interventionAbstinence-contingent housingNon-abstinence-contingent housing with high intensity case managementHousing vouchersResidential treatment These interventions seem to have similar beneficial effects, so it is unclear which of these is best with respect to reducing homelessness and increasing housing stability.What do the findings of this review mean?: A range of housing programs and case management interventions appear to reduce homelessness and improve housing stability, compared to usual services.However, there is uncertainty in this finding as most the studies have risk of bias due to poor reporting, lack of blinding, or poor randomization or allocation concealment of participants. In addition to the general need for better conducted and reported studies, there are specific gaps in the research with respect to: 1) disadvantaged youth; 2) abstinence-contingent housing with case management or day treatment; 3) non-abstinence contingent housing comparing group vs independent living; 4) Housing First compared to interventions other than usual services, and; 5) studies outside of the USA.How up-to-date is this review?: The review authors searched for studies published up to January 2016. This Campbell systematic review was published in February 2018.

Executive summary

Background: The United Nations Universal Declaration of Human Rights (Article 25) states that everyone has a right to housing. However, this right is far from being realized for many people worldwide. According to the United Nations High Commissioner for Refugees (UNHCR), there are approximately 100 million homeless people worldwide. The aim of this report is to contribute evidence to inform future decision making and practice for preventing and reducing homelessness.Objectives: To identify, appraise and summarize the evidence on the effectiveness of housing programs and case management to improve housing stability and reduce homelessness among people who are homeless or at-risk of becoming homeless.Search methods: We conducted a systematic review in accordance with the Norwegian Knowledge Centre's handbook. We systematically searched for literature in relevant databases and conducted a grey literature search which was last updated in January 2016.Selection criteria: Randomized controlled trials that included individuals who were already, or at-risk of becoming, homeless were included if they examined the effectiveness of relevant interventions on homelessness or housing stability. There were no limitations regarding language, country or length of homelessness. Two reviewers screened 2,918 abstracts and titles for inclusion. They read potentially relevant references in full, and included relevant studies in the review.Data collection and analysis: We pooled the results and conducted meta-analyses when possible. Our certainty in the primary outcomes was assessed using the Grading of Recommendations Assessment, Development, and Evaluation for effectiveness approach (GRADE).Results: We included 43 relevant studies (described in 78 publications) that examined the effectiveness of housing programs and/or case management services on homelessness and/or housing stability. The results are summarized below. Briefly, we found that the included interventions performed better than the usual services in all comparisons. However, certainty in the findings varied from very low to moderate. Most of the studies were assessed as having high risk of bias due to poor reporting, lack of blinding, or poor randomization and/or allocation concealment of participants.Case management: Case management is a process where clients are assigned case managers who assess, plan and facilitate access to health and social services necessary for the client's recovery. The intensity of these services can vary. One specific model is Critical time intervention, which is based on the same principles, but offered in three three-month periods that decrease in intensity.High intensity case management compared to usual services has generally more positive effects: It probably reduces the number of individuals who are homeless after 12-18 months by almost half (RR=0.59, 95%CI=0.41 to 0.87)(moderate certainty evidence); It may increase the number of people living in stable housing after 12-18 months and reduce the number of days an individual spends homeless (low certainty evidence), however; it may have no effect on the number of individuals who experience some homelessness during a two year period (low certainty evidence). When compared to low intensity case management, it may have little or no effect on time spent in stable housing (low certainty evidence).Critical time intervention compared to usual services may 1) have no effect on the number of people who experience homelessness, 2) lead to fewer days spent homeless, 3) lead to more days spent not homeless and, 4) reduce the amount of time it takes to move from shelter to independent housing (low certainty evidence).Abstinence-contingent housing programs: Abstinence-contingent housing is housing provided with the expectation that residents will remain sober. The results showed that abstinence-contingent housing may lead to fewer days spent homeless, compared with usual services (low certainty evidence).Non-abstinence-contingent housing programs: Non-abstinence-contingent housing is housing provided with no expectations regarding sobriety of residents. Housing First is the name of one specific non-abstinence-contingent housing program. When compared to usual services Housing First probably reduces the number of days spent homeless (MD=-62.5, 95%CI=-86.86 to -38.14) and increases the number of days in stable housing (MD=110.1, 95%CI=93.05 to 127.15) (moderate certainty evidence). In addition, it may increase the number of people placed in permanent housing after 20 months (low certainty evidence).Non-abstinence-contingent housing programs (not specified as Housing First) in combination with high intensity case management may reduce homelessness, compared to usual services (low certainty evidence). Group living arrangements may be better than individual apartments at reducing homelessness (low certainty evidence).Housing vouchers with case management: Housing vouchers is a housing allowance given to certain groups of people who qualify. The results showed that it mayreduce homelessness and improve housing stability, compared with usual services or case management (low certainty evidence).Residential treatment with case management: Residential treatment is a type of housing offered to clients who also need treatment for mental illness or substance abuse. We found that it mayreduce homelessness and improve housing stability, compared with usual services (low certainty evidence).Authors' conclusions: We found that a range of housing programs and case management interventions appear to reduce homelessness and improve housing stability, compared to usual services. The findings showed no indication of housing programs or case management resulting in poorer outcomes for homeless or at-risk individuals than usual services.Aside from a general need for better conducted and reported studies, there are specific gaps in the research. We identified research gaps concerning: 1)Disadvantaged youth; 2) Abstinence-contingent housing with case management or day treatment; 3) Non-abstinence contingent housing, specifically different living arrangements (group vs independent living); 4) Housing First compared to interventions other than usual services, and; 5) All interventions from contexts other than the USA.

The effectiveness of critical time intervention for abused women leaving women's shelters: a randomized controlled trial

Objectives

To examine the effectiveness of critical time intervention (CTI)—an evidence-based intervention—for abused women transitioning from women’s shelters to community living.

Methods

A randomized controlled trial was conducted in nine women’s shelters across the Netherlands. 136 women were assigned to CTI (n = 70) or care-as-usual (n = 66). Data were analyzed using intention-to-treat three-level mixed-effects models.

Results

Women in the CTI group had significant fewer symptoms of post-traumatic stress (secondary outcome) (adjusted mean difference − 7.27, 95% CI − 14.31 to − 0.22) and a significant fourfold reduction in unmet care needs (intermediate outcome) (95% CI 0.06–0.94) compared to women in the care-as-usual group. No differences were found for quality of life (primary outcome), re-abuse, symptoms of depression, psychological distress, self-esteem (secondary outcomes), family support, and social support (intermediate outcomes).

Conclusions

This study shows that CTI is effective in a population of abused women in terms of a reduction of post-traumatic stress symptoms and unmet care needs. Because follow-up ended after the prescribed intervention period, further research is needed to determine the full long-term effects of CTI in this population.

Critical Time Intervention for Homeless People Making the Transition to Community Living: A Randomized Controlled Trial

To help create an evidence base in Europe for effective interventions that improve the well-being of homeless people, we tested whether critical time intervention (CTI), a time-limited intervention developed to support vulnerable people during times of transition, is effective outside the United States. For this multicenter, parallel-group randomized controlled trial, 183 adults who were moving from shelters in the Netherlands to supported or independent housing were allocated to CTI or care-as-usual. The primary outcome was number of days rehoused, which was assessed by interviewing participants four times during a 9-month follow-up. Outcomes were analyzed with three-level mixed-effects models. The primary outcome did not differ between groups. CTI had a significant effect on family support and, for people experiencing less social support, psychological distress. Groups did not differ significantly on social support, fulfillment of care needs, quality of life, self-esteem, excessive alcohol use, or cannabis use. Because few participants were homeless at 9 months, more research is needed to establish whether CTI can prevent long-term recurrent homelessness. Given recent emphasis on informal support in public services and positive effects of CTI on family support and psychological distress, CTI is a fitting intervention for Dutch shelter services.

Critical time Intervention for Severely mentally ill Prisoners (CrISP): a randomised controlled trial

Background

The transition from prison to community is difficult for prisoners with mental illness. Critical time intervention (CTI) is designed to provide intensive support to meet health, social care and resettlement needs through close working between client and key worker pre, and up to 6 weeks post, release.

Objectives

To establish whether or not CTI is effective in (1) improving engagement of discharged male prisoners who have mental illness with community mental health teams (CMHTs) and (2) providing practical support with housing, finance and re-establishing social networks.

Trial design

A multicentre, parallel-group randomised controlled trial, with follow-up at 6 weeks and at 6 and 12 months. A subset of prisoners and case managers participated in a complementary qualitative study.

Setting

Eight English prisons.

Participants

One hundred and fifty adult male prisoners, convicted or remanded, cared for by mental health in-reach teams and diagnosed with severe mental illness, with a discharge date within 6 months of the point of recruitment.

Intervention

Participants were randomised to either the intervention or the control (treatment as usual). The intervention group was assigned a case manager who assessed mental and physical health before and following release, made appropriate links to health, housing and financial services and supported the re-establishment of family/peer contact.

Outcome

The primary outcome measure was engagement with a CMHT 6 weeks post discharge. Secondary outcomes included contact with mental health services at 6 and 12 months. A health economic evaluation was undertaken using service contact at the follow-up time points. We were unable to assess the intervention’s effect on reoffending and longer-term health-care use because of study delays.

Results

One hundred and fifty prisoners were recruited: 72 were randomised to the intervention and 78 were randomised to the control. Engagement with teams at 6 weeks was 53% for the intervention group compared with 27% for the control group [95% confidence interval (CI) 0.13% to 0.78%;p = 0.012]. At 6 months’ follow-up, intervention participants showed continued increase in engagement with teams compared with control participants (95% CI 0.12% to 0.89%;p = 0.029); there were no significant differences at 12 months. Increased engagement resulted in higher levels of service use and costs for the intervention than for the control. Qualitative data showed the intervention group reporting better continuity of care and improved access to services.

Conclusion

The intervention significantly improved contact with services at 6 weeks, although at a higher cost than the control. This is important as, in the days and weeks following release, recently released individuals are at a particularly high risk of suicide and drug overdose. Further research is required to establish how teams can better maintain contact with clients when the intervention ends.

Future work

Further studies are indicated for groups with different needs, for example women, young prisoners and those in police custody, and at other transition points, for example following arrest and short-term custody, and at points of transition between different mental health services.

Effectiveness of a Brief Care Management Intervention for Reducing Psychiatric Hospitalization Readmissions

This study examines a recovery-focused care management bridging strategy implemented during time of inpatient stay with the goal to increase engagement in aftercare and reduce early psychiatric readmissions. The sample included 195 individuals who received care from a large psychiatric specialty hospital. Eighty-seven individuals were assigned to receive the intervention, while 108 individuals were assigned to the control group. Individuals in the intervention group received a brief interview prior to inpatient discharge plus usual care, and individuals in the control group received usual care. After controlling for age, living situation, and utilization, individuals in the control group were more likely to be readmitted within 30 days of an index readmission than individuals in the intervention group (OR = 2.44, p = .02). Bridging strategies utilized prior to discharge for individuals at higher risk of early mental health inpatient readmission may be used as an effective alternative to more costly interventions.

Online Versus Face-To-Face Training of Critical Time Intervention: A Matching Cluster Randomized Trial

This study examined the effectiveness of online education to providers who serve people experiencing homelessness, comparing online and face-to-face training of Critical Time Intervention (CTI), an evidence-based case management model. The authors recruited 184 staff from 19 homeless service agencies to participate in one of two training conditions: (a) Online Training + Community of Practice or (b) Face-to-Face Training + Telephone Consultation. Each group received 24 hours of instruction and support. Through baseline, follow-up, and nine-month post-training surveys, the authors examined satisfaction, knowledge gains, knowledge retention, and readiness to implement CTI. While satisfaction rates were higher among participants in the face-to-face group, the two training conditions produced comparable pre/post knowledge gains. Furthermore, both groups showed increased knowledge retention scores at nine-month follow up, with the online group scoring higher than the face-to-face group.

Brief case management versus usual care for frequent users of emergency departments: the Coordinated Access to Care from Hospital Emergency Departments (CATCH-ED) randomized controlled trial

Background

Frequent users of hospital emergency departments (EDs) are a medically and socially vulnerable population. This article describes the rationale for a brief case management intervention for frequent ED users with mental health and/or addiction challenges and the design of a randomized trial assessing its effectiveness.

Methods/Design

Eligible participants are adults in a large urban centre with five or more ED visits in the past year, with at least one prior visit for a mental health or addictions reason. Participants (N = 166) will be randomized to either 4 to 6 months of brief case management or usual care, and interviewed every 3 months for 1 year. Consent will be sought to access administrative health records. A subset of participants (N = 20) and service providers (N = 13) will participate in qualitative data collection.

Discussion

Addressing the needs of frequent ED users is a priority in many jurisdictions. This study will provide evidence on the effectiveness of brief case management, compared to usual care, on reducing ED visits among frequent ED users experiencing mental health or substance misuse problems, and inform policy and practice in this important area.

Treatment engagement of individuals experiencing mental illness: review and update

Individuals living with serious mental illness are often difficult to engage in ongoing treatment, with high dropout rates. Poor engagement may lead to worse clinical outcomes, with symptom relapse and rehospitalization. Numerous variables may affect level of treatment engagement, including therapeutic alliance, accessibility of care, and a client's trust that the treatment will address his/her own unique goals. As such, we have found that the concept of recovery-oriented care, which prioritizes autonomy, empowerment and respect for the person receiving services, is a helpful framework in which to view tools and techniques to enhance treatment engagement. Specifically, person-centered care, including shared decision making, is a treatment approach that focuses on an individual's unique goals and life circumstances. Use of person-centered care in mental health treatment models has promising outcomes for engagement. Particular populations of people have historically been difficult to engage, such as young adults experiencing a first episode of psychosis, individuals with coexisting psychotic and substance use disorders, and those who are homeless. We review these populations and outline how various evidence-based, recovery-oriented treatment techniques have been shown to enhance engagement. Our review then turns to emerging treatment strategies that may improve engagement. We focus on use of electronics and Internet, involvement of peer providers in mental health treatment, and incorporation of the Cultural Formulation Interview to provide culturally competent, person-centered care. Treatment engagement is complex and multifaceted, but optimizing recovery-oriented skills and attitudes is essential in delivery of services to those with serious mental illness.

Longitudinal Impact of a Family Critical Time Intervention on Children in High-Risk Families Experiencing Homelessness: A Randomized Trial

A randomized trial compared effects of a Family Critical Time Intervention (FCTI) to usual care for children in 200 newly homeless families in which mothers had diagnosable mental illness or substance problems. Adapted from an evidence-based practice to prevent chronic homelessness for adults with mental illnesses, FCTI combines housing and structured, time-limited case management to connect families leaving shelter with community services. Families were followed at five time points over 24 months. Data on 311 children-99 ages 1.5-5 years, 113 ages 6-10 years, and 99 ages 11-16 years-included mother-, teacher-, and child-reports of mental health, school experiences, and psychosocial well-being. Analyses used hierarchical linear modeling to investigate intervention effects and changes in child functioning over time. Referral to FCTI reduced internalizing and externalizing problems in preschool-aged children and externalizing for adolescents 11-16. The intervention led to declines in self-reported school troubles for children 6-10 and 11-16. Both experimental and control children in all age groups showed reductions in symptoms over time. Although experimental results were scattered, they suggest that FCTI has the potential to improve mental health and school outcomes for children experiencing homelessness.

Developing community support for homeless people with mental illness in transition

To facilitate effective transitional services and enhance continuity of care among people with mental illness, this grounded theory study explored the practice of developing community support in critical time intervention (CTI), a time-limited, shortterm psychosocial rehabilitation program designed to facilitate the critical transition from institutional to community settings. Semi-structured, one-on-one interviews with twelve CTI workers were analyzed. Results show that CTI workers self-identified as an "extra support" to develop community ties that will help clients sustain stable housing. Their practice of community support development was represented by a transient triangular relationship model, involving three dyadic relationships (worker-client, worker-primary support, primary support-client) as the building blocks and specific strategies to facilitate the relational transition. Findings also detailed identification of community supports, collaboration and boundary issues in working with primary supports, and engagement with clients in this transitional process. Recommendations were drawn from findings to enhance broad discharge and transitional services.

Efficacy of community treatments for schizophrenia and other psychotic disorders: a literature review

BACKGROUND

In Chile, the clinical guidelines "for the treatment of people from first episode of schizophrenia" aim to support individuals with schizophrenia to live independently, establishment occupational goals, and gain an adequate quality of life and social interaction. This requires the implementation of a treatment model that integrates psychosocial and pharmacological dimensions. Community intervention strategies ensure the achievement of these goals.

OBJECTIVES

This study compiles and synthesizes available scientific evidence from the last 14 years on the effectiveness of community intervention strategies for schizophrenia and related psychotic disorders.

METHODOLOGY

An electronic search was carried out using PUBMED, LILACS, and Science Direct as databases. Criteria of inclusion: (i) randomized clinical trials, (ii) Community-based interventions, (iii) diagnosis of schizophrenia or related psychotic disorder (section F2 of ICD-10).

EXCLUSION CRITERIA

(i) treatments exclusively pharmacological, (ii) interventions carried out in inpatient settings, (iii) bipolar affective disorder or substance-induced psychosis (greater than 50% of sample).

RESULTS

Sixty-six articles were reviewed. Community strategies for integrated treatment from the first outbreak of schizophrenia significantly reduced negative and psychotic symptoms, days of hospitalization, and comorbidity with substance abuse and improved global functioning and adherence to treatment. In other stages, there were improved outcomes in negative and positive symptoms and general psychopathology. Psychoeducation for patients and families reduced the levels of self-stigma and domestic abuse, as well as improved knowledge of the disease and treatment adherence. Training focused on cognitive, social, and labor skills has been shown to improve yields in social functioning and employment status.

CONCLUSION

Community-based intervention strategies are widely supported in the treatment of patients with schizophrenia.

Inadequate housing among families under investigation for child abuse and neglect: prevalence from a national probability sample

This study aimed to estimate the prevalence of inadequate housing that threaten out-of-home placement among families under investigation by child welfare. Data came from the National Survey of Child and Adolescent Well-Being, a nationally representative longitudinal survey of child welfare-involved families. Child protective services caseworkers as well as caregivers provided information on families whose child remained in the home after initial investigation (N = 3,867). Multilevel latent class analyses tested the presence of inadequately housed subgroups using 4 housing problem indicators at baseline. Logistic regressions assessed convergent and predictive validity. A two class latent solution best fit the data. Findings indicated that inadequate housing contributed to risk for out-of-home placement in approximately 16 % of intact families under investigation by child protective services. These families were 4 times more likely to need housing services 12 months later. Federal legislation emphasizes integration of social services as necessary to end homelessness. This study demonstrates overlap across public agencies. Enhanced coordination of child welfare and housing services facilitates interventions to prevent and mitigate homelessness.

Effectiveness of case management for homeless persons: a systematic review

We reviewed the literature on standard case management (SCM), intensive case management (ICM), assertive community treatment (ACT), and critical time intervention (CTI) for homeless adults. We searched databases for peer-reviewed English articles published from 1985 to 2011 and found 21 randomized controlled trials or quasi-experimental studies comparing case management to other services. We found little evidence for the effectiveness of ICM. SCM improved housing stability, reduced substance use, and removed employment barriers for substance users. ACT improved housing stability and was cost-effective for mentally ill and dually diagnosed persons. CTI showed promise for housing, psychopathology, and substance use and was cost-effective for mentally ill persons. More research is needed on how case management can most effectively support rapid-rehousing approaches to homelessness.

The effectiveness of critical time intervention for abused women and homeless people leaving Dutch shelters: study protocol of two randomised controlled trials

Background

One of the main priorities of Dutch organisations providing shelter services is to develop evidence-based interventions in the care for abused women and homeless people. To date, most of these organisations have not used specific intervention models and the interventions which have been implemented rarely have an empirical and theoretical foundation. The present studies aim to examine the effectiveness of critical time intervention (CTI) for abused women and homeless people.

Methods

In two multi-centre randomised controlled trials we investigate whether CTI, a time-limited (nine month) outreach intervention, is more effective than care-as-usual for abused women and homeless people making the transition from shelter facilities to supported or independent housing. Participants were recruited in 19 women’s shelter facilities and 22 homeless shelter facilities across The Netherlands and randomly allocated to the intervention group (CTI) or the control group (care-as-usual). They were interviewed four times in nine months: once before leaving the shelter, and then at three, six and nine months after leaving the shelter. Quality of life (primary outcome for abused women) and recurrent loss of housing (primary outcome for homeless people) as well as secondary outcomes (e.g. care needs, self-esteem, loneliness, social support, substance use, psychological distress and service use) were assessed during the interviews. In addition, the model integrity of CTI was investigated during the data collection period.

Discussion

Based on international research CTI is expected to be an appropriate intervention for clients making the transition from institutional to community living. If CTI proves to be effective for abused women and homeless people, shelter services could include this case management model in their professional standards and improve the (quality of) services for clients.

Continuity of care for people with psychotic illness: its relationship to clinical and social functioning

BACKGROUND

The relationship between continuity of care and user characteristics or outcomes has rarely been explored. The ECHO study operationalized and tested a multi-axial definition of continuity of care, producing a seven-factor model used here.

AIMS

To assess the relationship between user characteristics and established components of continuity of care, and the impact of continuity on clinical and social functioning.

METHODS

The sample comprised 180 community mental health team users with psychotic disorders who were interviewed at three annual time-points, to assess their experiences of continuity of care and clinical and social functioning. Scores on seven continuity factors were tested for association with user-level variables.

RESULTS

Improvement in quality of life was associated with better Experience & Relationship continuity scores (better user-rated continuity and therapeutic relationship) and with lower Meeting Needs continuity factor scores. Higher Meeting Needs scores were associated with a decrease in symptoms.

CONCLUSION

Continuity is a dynamic process, influenced significantly by care structures and organizational change.

The impact of critical time intervention in reducing psychiatric rehospitalization after hospital discharge

OBJECTIVES

This study examined the impact of critical time intervention (CTI) in reducing rehospitalization among formerly homeless individuals with severe and persistent mental illness after discharge from inpatient psychiatric treatment.

METHODS

CTI is a nine-month care coordination intervention designed to support persons with severe mental illness in the transition from institutions to community living. After discharge from inpatient psychiatric treatment, 150 previously homeless men and women were randomly assigned to receive either usual services only or CTI in addition to usual services. Study participants were assessed every six weeks for 18 months after entering the community.

RESULTS

At the end of the follow-up period, psychiatric rehospitalization was significantly lower for the group assigned to CTI compared with the usual services group (odds ratio=.11, 95% confidence interval=.01-.96).

CONCLUSIONS

This study demonstrated that CTI, primarily designed to prevent recurrent homelessness, also reduced the occurrence of rehospitalization after discharge.

Continuity of care for recently released prisoners with mental illness: a pilot randomised controlled trial testing the feasibility of a Critical Time Intervention

AIMS

Prisoners with mental illness on release from prison often face complex challenges with little support, leading to poor clinical and social outcomes. This feasibility study aimed to see whether a Critical Time Intervention (CTI) in the first weeks post-release effectively connects mentally ill prisoners with social, clinical, housing, and welfare services on leaving prison. The study took place in 2007 and involved local prisons in London and Manchester.

METHODS

A pilot randomised controlled trial in which CTI was compared to Treatment as Usual (TAU).

RESULTS

Sixty prisoners were randomised in the trial, with outcome measures completed on 23. A higher proportion of prisoners in CTI group were in contact with services at follow-up than those receiving TAU. CTI prisoners were significantly more likely to be receiving medication, and be registered with a General Practitioner (GP) than those in the TAU group.

CONCLUSIONS

Continuity of care for prisoners with severe mental illness can be improved by working with them to identify their needs prior to release, and by assisting them to engage effectively to the necessary agencies in the community.

Cost savings from assertive community treatment services in an era of declining psychiatric inpatient use

OBJECTIVE

To assess, during a period of decreasing psychiatric inpatient utilization, cost savings from Assertive Community Treatment (ACT) programs for individuals with severe mental illnesses.

DATA SOURCE

U.S. Department of Veterans Affairs' (VA) national administrative data for entrants into ACT programs.

STUDY DESIGN

An observational study of the effects of ACT enrollment on mental health inpatient utilization and costs in the first 12 months following enrollment. ACT enrollees (N = 2010) were propensity score matched to ACT-eligible non-enrollees (N = 4020). An instrumental variables generalized linear regression approach was used to estimate enrollment effects.

RESULTS

Instrumental variables estimates indicate that between FY2001 and FY2004, entry into ACT resulted in a net increase of $4529 in VA costs. Trends in inpatient use among ACT program entrants suggest this effect remained stable after FY2004. However, eligibility for ACT declined 37 percent, because fewer patients met an eligibility standard based on high prior psychiatric inpatient use.

CONCLUSIONS

Savings from ACT programs depend on new enrollees' intensity of psychiatric inpatient utilization prior to entering the ACT program. Although a program eligibility standard based on prior psychiatric inpatient use helped to sustain the savings from VA ACT programs, over time, it also resulted in an unintended narrowing of program eligibility.

[Adaptation of critical time intervention for use in Brazil and its implementation among users of psychosocial service centers (CAPS) in the municipality of Rio de Janeiro]

Brazilian Psychiatric Reform proposes a mental healthcare model based on the implementation of a community-based service network, in which Psychosocial Service Centers (CAPS) play a fundamental role. The report presents the results of a pilot study which aimed to adapt Critical Time Intervention to the Brazilian context, and to test its feasibility to provide it to persons with schizophrenic spectrum disorders who are enrolled in CAPS of Rio de Janeiro.

METHODS

The research design included three inter-related phases. Phase one consisted in carrying out qualitative and quantitative field work. This phase included mapping out the socio-demographic, clinical and service utilization data of CAPS users, as well as assessing the mental health needs of participants in the study. The second phase consisted in translation of the CTI clinical manual to include the adaptations made for use in Brazil, which were based on data collected in the first phase, as well as training individuals with moderate education as CTI intervention workers. The third phase consisted of pilot implementation of the adapted intervention among a group of individuals with schizophrenia spectrum disorders enrolled in CAPS, but with difficulties in being included in treatment.

Helping homeless individuals with co-occurring disorders: the four components

Homeless individuals with co-occurring disorders (CODs) of severe mental illness and substance use disorder are one of the most vulnerable populations. This article provides practitioners with a framework and strategies for helping this client population. Four components emerged from a literature review: (1) ensuring an effective transition for individuals with CODs from an institution (such as a hospital, foster care, prison, or residential program) into the community, a particularly important component for clients who were previously homeless, impoverished, or at risk of homelessness; (2) increasing the resources of homeless individuals with CODs by helping them apply for government entitlements or supported employment (3) linking homeless individuals to supportive housing, including housing first options as opposed to only treatment first options, and being flexible in meeting their housing needs; and (4) engaging homeless individuals in COD treatment, incorporating modified assertive community treatment, motivational interviewing, cognitive-behavioral therapy, contingency management, and COD specialized self-help groups.

National dissemination of supported housing in the VA: model adherence versus model modification

OBJECTIVE

The continuing development and dissemination of emerging evidence-based practices may be facilitated by the availability of descriptive information on the actual delivery of the service, and its variability, across sites. This paper presents data on the participation of 2,925 homeless veterans in the Housing and Urban Development-Veterans Affairs Supported Housing (HUD-VASH) program at 36 sites across the country, for up to five years. While most conceptual models emphasize rapid placement, sustained intensive case management, rehabilitation services, and "permanent" housing, no program has yet presented empirical data on the actual delivery of such services over an extended period of time.

METHODS

Using extensive longitudinal data from the VA's national homeless outreach program, the Health Care for Homeless Veterans (HCHV) program, a quantitative portrait presents what happens in supported housing in a large real-world dissemination effort.

RESULTS

Program entry to HUD-VASH was generally slow with 108 days (sd = 92 days) on average passing between program entry and housing placement. Total program participation lasted 2.6 years on average (sd = 1.6 years)-just half of the possible 5 years. Service delivery became substantially less intensive over time by several measures, and three-fourths of the veterans terminated within five years, although the vast majority (82%) were housed at the time. Few veterans received rehabilitation services (6%) or employment assistance (17%) and most service delivery focused on obtaining housing.

CONCLUSIONS

These data suggest that real-world supported housing programs may not adhere to the prevalent model descriptions either because of implementation failure or because veteran needs and preferences differ from those suggested by that model.

Needs-oriented discharge planning and monitoring for high utilisers of psychiatric services (NODPAM): design and methods

Background

Attempts to reduce high utilisation of psychiatric inpatient care by targeting the critical time of hospital discharge have been rare.

Methods

This paper presents design and methods of the study "Effectiveness and Cost-Effectiveness of Needs-Oriented Discharge Planning and Monitoring for High Utilisers of Psychiatric Services" (NODPAM), a multicentre RCT conducted in five psychiatric hospitals in Germany. Inclusion criteria are receipt of inpatient psychiatric care, adult age, diagnosis of schizophrenia or affective disorder, defined high utilisation of psychiatric care during two years prior to the current admission, and given informed consent. Consecutive recruitment started in April 2006. Since then, during a period of 18 months, comprehensive outcome data of 490 participants is being collected at baseline and during three follow-up measurement points.

The manualised intervention applies principles of needs-led care and focuses on the inpatient-outpatient transition. A trained intervention worker provides two intervention sessions: (a) Discharge planning: Just before discharge with the patient and responsible clinician at the inpatient service; (b) Monitoring: Three months after discharge with the patient and outpatient clinician. A written treatment plan is signed by all participants after each session.

Primary endpoints are whether participants in the intervention group will show fewer hospital days and readmissions to hospital. Secondary endpoints are better compliance with aftercare, better clinical outcome and quality of life, as well as cost-effectiveness and cost-utility.

Discussion

If a needs-oriented discharge planning and monitoring proves to be successful in this RCT, a tool will be at hand to improve patient outcome and reduce costs via harmonising fragmented mental health service provision.

Critical Time Intervention: an empirically supported model for preventing homelessness in high risk groups

Critical Time Intervention (CTI) is designed to prevent recurrent homelessness among persons with severe mental illness by enhancing continuity of care during the transition from institutional to community living. After providing the background and rationale of CTI, we describe the elements of the model and summarize the status of existing research on its effectiveness. We then briefly illustrate how the CTI model has begun to be adapted and implemented by providing a case example of a homeless woman's transition from shelter to housing. Finally, we consider plans for the further adaptation, testing and dissemination of CTI in other populations and service delivery settings.
