Housing the homeless mentally ill: a longitudinal study of a treatment approach

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.

Interventions to improve social circumstances of people with mental health conditions: a rapid evidence synthesis

BACKGROUND

Poor social circumstances can induce, exacerbate and prolong symptoms of mental health conditions, while having a mental health condition can also lead to worse social outcomes. Many people with mental health conditions prioritise improvement in social and functional outcomes over reduction in clinical symptoms. Interventions that improve social circumstances in this population should thus be considered a priority for research and policy.

METHODS

This rapid evidence synthesis reports on randomised controlled trials of interventions to improve social circumstances across eight social domains (Housing and homelessness; money and basic needs; work and education; social isolation and connectedness; family, intimate and caring relationships; victimisation and exploitation; offending; and rights, inclusion and citizenship) in people with mental health conditions. Economic evaluations were also identified. A comprehensive, stepped search approach of the Cochrane library, MEDLINE, Embase, PsycINFO, Web of Science and Scopus was conducted.

RESULTS

One systematic review and 102 randomised controlled trials were included. We did not find RCT evidence for interventions to improve family, intimate and caring relationships and only one or two trials for each of improving money and basic needs, victimisation and exploitation, and rights, inclusion and citizenship. Evidence from successful interventions in improving homelessness (Housing First) and employment (Individual Placement and Support) suggests that high-intensity interventions which focus on the desired social outcome and provide comprehensive multidisciplinary support could influence positive change in social circumstances of people with mental health conditions. Objective social isolation could be improved using a range of approaches such as supported socialisation and social skills training but interventions to reduce offending showed few benefits. Studies with cost and cost-effectiveness components were generally supportive of interventions to improve housing and vocational outcomes. More research is needed to ensure that social circumstances accompanied by high risks of further exacerbation of mental health conditions are adequately addressed.

CONCLUSIONS

Although there is a large body of literature examining how to support some aspects of life for people with mental health conditions, more high-quality evidence is required in other social domains. Integration into mental health services of interventions targeting social circumstances could significantly improve a number of social outcomes.

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.

Seeking shelter: homelessness and COVID-19

Those experiencing homelessness in Canada are impacted inequitably by COVID-19 due to their increased exposure, vulnerability of environment and medical comorbidities, and their lack of access to preventive care and treatment in the context of the pandemic. In shelter environments one is unable to effectively physically distance, maintain hygiene, obtain a test, or isolate. As a result, unique strategies are required for this population to protect them and those who serve them. Recommendations are provided to reduce or prevent further negative consequences from the COVID-19 pandemic for people experiencing homelessness. These recommendations were informed by a systematic review of the literature, as well as a jurisdictional scan. Where evidence did not exist, expert consensus from key providers and those experiencing homelessness throughout Canada was included. These recommendations recognize the need for short-term interventions to mitigate the immediate risk to this community, including coordination of response, appropriate precautions and protective equipment, reducing congestion, cohorting, testing, case and contact management strategies, dealing with outbreaks, isolation centres, and immunization. Longer-term recommendations are also provided with a view to ending homelessness by addressing the root causes of homelessness and by the provision of adequate subsidized and supportive housing through a Housing First strategy. It is imperative that meaningful changes take place now in how we serve those experiencing homelessness and how we mitigate specific vulnerabilities. These recommendations call for intersectoral, collaborative engagement to work for solutions targeted towards protecting the most vulnerable within our community through both immediate actions and long-term planning to eliminate homelessness.

Permanent Supportive Housing With Housing First to Reduce Homelessness and Promote Health Among Homeless Populations With Disability: A Community Guide Systematic Review

CONTEXT

Poor physical and mental health and substance use disorder can be causes and consequences of homelessness. Approximately 2.1 million persons per year in the United States experience homelessness. People experiencing homelessness have high rates of emergency department use, hospitalization, substance use treatment, social services use, arrest, and incarceration.

OBJECTIVES

A standard approach to treating homeless persons with a disability is called Treatment First, requiring clients be "housing ready"-that is, in psychiatric treatment and substance-free-before and while receiving permanent housing. A more recent approach, Housing First, provides permanent housing and health, mental health, and other supportive services without requiring clients to be housing ready. To determine the relative effectiveness of these approaches, this systematic review compared the effects of both approaches on housing stability, health outcomes, and health care utilization among persons with disabilities experiencing homelessness.

DESIGN

A systematic search (database inception to February 2018) was conducted using 8 databases with terms such as "housing first," "treatment first," and "supportive housing." Reference lists of included studies were also searched. Study design and threats to validity were assessed using Community Guide methods. Medians were calculated when appropriate.

ELIGIBILITY CRITERIA

Studies were included if they assessed Housing First programs in high-income nations, had concurrent comparison populations, assessed outcomes of interest, and were written in English and published in peer-reviewed journals or government reports.

MAIN OUTCOME MEASURES

Housing stability, physical and mental health outcomes, and health care utilization.

RESULTS

Twenty-six studies in the United States and Canada met inclusion criteria. Compared with Treatment First, Housing First programs decreased homelessness by 88% and improved housing stability by 41%. For clients living with HIV infection, Housing First programs reduced homelessness by 37%, viral load by 22%, depression by 13%, emergency departments use by 41%, hospitalization by 36%, and mortality by 37%.

CONCLUSIONS

Housing First programs improved housing stability and reduced homelessness more effectively than Treatment First programs. In addition, Housing First programs showed health benefits and reduced health services use. Health care systems that serve homeless patients may promote their health and well-being by linking them with effective housing services.

Health status, quality of life, residential stability, substance use, and health care utilization among adults applying to a supportive housing program

Supportive housing, defined as subsidized housing in conjunction with site-based social services, may help improve the health and residential stability of highly disadvantaged individuals. This study examined changes in health status, quality of life, substance use, health care utilization, and residential stability among 112 homeless and vulnerably housed individuals who applied to a supportive housing program in Toronto, Canada, from December 2005 to June 2007. Follow-up interviews were conducted every 6 months for 18 months. Comparisons were made between individuals who were accepted into the program (intervention) and those who were wait-listed (usual care) using repeated-measures analyses. Individuals who were accepted into the housing program experienced significantly greater improvements in satisfaction with living situation compared with individuals in the usual care group (time, F(3,3,261) = 47.68, p < 0.01; group × time, F(3,3,261) = 14.60, p < 0.01). There were no significant differences in other quality of life measures, health status, health care utilization, or substance use between the two groups over time. Significant improvement in residential stability occurred over time, independent of assigned housing group (time, F(3,3,261) = 9.96, p < 0.01; group × time, F(3,3,261) = 1.74, p = 0.17). The ability to examine the effects of supportive housing on homeless individuals was limited by the small number of participants who were literally homeless at baseline and by the large number of participants who gained stable housing during the study period regardless of their assigned housing status. Nonetheless, this study shows that highly disadvantaged individuals with a high prevalence of poor physical and mental health and substance use can achieve stable housing.

Fundamental Causes of Housing Loss among Persons Diagnosed with Serious and Persistent Mental Illness: A Theoretically Guided Test

Previous research on housing loss among severely mentally ill persons who have been placed in housing after being homeless has been largely atheoretical and has yielded inconsistent results. We develop a theory of housing loss based on identifying fundamental causes-problems in motives, means and social situation-and test these influences in a longitudinal, randomized comparison of housing alternatives. As hypothesized, individuals were more likely to lose housing if they had a history of alcohol or drug abuse, desired strongly to live independently contrary to clinician recommendations, or were African Americans placed in independent housing. Deficits in daily functioning did not explain these influences, but contributed to risk of housing loss. Our results demonstrate the importance of substance abuse, the value of distinguishing support preferences from support needs, and the necessity of explaining effects of race within a social context and thus should help to improve comparative research.

Lessening Homelessness Among Persons with Mental Illness: A Comparison of Five Randomized Treatment Trials

We evaluate the influence of housing, services, and individual characteristics on housing loss among formerly homeless mentally ill persons who participated in a five-site (4-city) study in the U.S. Housing and service availability were manipulated within randomized experimental designs and substance abuse and other covariates were measured with a common protocol. Findings indicate that housing availability was the primary predictor of subsequent ability to avoid homelessness, while enhanced services reduced the risk of homelessness if housing was also available. Substance abuse increased the risk of housing loss in some conditions in some projects, but specific findings differed between projects and with respect to time spent in shelters and on the streets. We identify implications for research on homeless persons with mental illness that spans different national and local contexts and involves diverse ethnic groups.

Twelve-month client outcomes and service use in a multisite project for chronically homelessness adults

Collaborative Initiative to Help End Chronic Homelessness clients (N = 734) were enrolled into an evaluation wherein assessments at program entry and quarterly thereafter addressed sociodemographic characteristics, health status, and a wide range of service use and outcomes data. Mixed linear regression analysis was used to test for significant changes over time. The average number of days housed during the previous 3 months increased dramatically from 18 at baseline to 83 by year's end. Significant improvements of more modest magnitude were also observed in overall quality of life, mental health functioning, and reduced psychological distress. Alcohol and drug problems remained largely unchanged over time, among clients overall. However, among baseline drug users crack, cocaine, and marijuana use decreased by 28-50% over the follow-up period. Total quarterly health cost estimates declined by 50%, as well, from $6,832 to $3,376. These findings suggest that adults who have experienced chronic homelessness may be successfully housed and can maintain their housing, when provided with comprehensive services.

Methodological advances in the use of recidivism rates to assess mental health treatment programs

This study of recidivism rates within a state psychiatric system identifies and controls for a number of flaws in other recidivism studies and provides one of the few direct comparisons between different mental health programs using recidivism rates as a dependent variable. It is not an attempt to predict the likelihood of an individual patient's recidivism or to improve the treatment provided the individual patient. Instead, it is an endeavor to address the issue of using recidivism rates to assess a treatment program's effectiveness and to examine such treatment at the macro- or system wide level.

Copenhagen Community Psychiatric Project (CCPP): characteristics and treatment of homeless patients in the psychiatric services after introduction of community mental health centres

The main purpose of the study was to describe the characteristics of homeless psychiatric patients, and to compare the treatment they are offered to that offered to domiciled patients by the psychiatric services. Another purpose was to analyse the prevalence of homelessness among psychiatric patients before and after the introduction of community mental health centres in Copenhagen. Cross-sectional studies were conducted in two intervention and two control districts before and after introduction of the new treatment modalities. In 1991, 80 of 1008 patients (8%) were homeless. Male sex, young age, living on general welfare, schizophrenia and alcohol or substance abuse were the factors that most markedly differentiated homeless from domiciled patients. Compared with the treatment of domiciled patients, the homeless were more likely to be offered no further treatment after consultation in a psychiatric emergency and, if admitted, they were more likely to be placed in locked wards, given compulsory medication, and medicated with depot neuroleptics. The homeless were also less likely to be offered psychotherapy and consultation with a social worker. Schizophrenia and alcohol or substance abuse characterised the majority of the patients discharged homeless. In the intervention districts, the number of homeless patients in contact with the psychiatric services was found to increase at the same rate as the number of all patients in contact with the psychiatric services. In the control districts, no changes in prevalence of homeless patients or other patients in contact with the psychiatric services occurred. It is concluded that homeless psychiatric patients comprise a difficult patient group, with problems of schizophrenia, substance abuse and lack of motivation for treatment. It is recommended that special efforts be made to create housing facilities that fit the needs of different types of homeless patients, and that the homeless mentally ill are assisted in obtaining and maintaining an acceptable housing situation.

Preventing recurrent homelessness among mentally ill men: a "critical time" intervention after discharge from a shelter

OBJECTIVES

This study examined a strategy to prevent homelessness among individuals with severe mental illness by providing a bridge between institutional and community care.

METHODS

Ninety-six men with severe mental illness who were entering community housing from a shelter institution were randomized to receive 9 months of a "critical time" intervention plus usual services or usual services only. The primary analysis compared the mean number of homeless nights for the two groups during the 18-month follow-up period. To elucidate time trends, survival curves were used.

RESULTS

Over the 18-month follow-up period, the average number of homeless nights was 30 for the critical time intervention group and 91 for the usual services group. Survival curves showed that after the 9-month period of active intervention, the difference between the two groups did not diminish.

CONCLUSIONS

Strategies that focus on a critical time of transition may contribute to the prevention of recurrent homelessness among individuals with mental illness, even after the period of active intervention.

Assessing homeless mentally ill persons for permanent housing: screening for safety

Although placement in community housing is a frequent intervention with populations of seriously mentally ill homeless individuals, there has been little formal investigation of the criteria used by clinicians in screening individuals for such placement. In this paper, we describe screening a population of 303 homeless people with severe mental illness for placement in independent apartments. We assess subjects' level of risk along multiple dimensions and determine the contribution of each risk dimension to the final safety decision. In addition, we evaluate the validity of the risk measures with other measures of clinical condition. Two-thirds of the sample were judged as safe for independent living. Assaultiveness was the most frequent risk identified, followed by self-destructiveness, substance abuse, and medication non-compliance. The final safety decision was associated most strongly with assaultiveness, self-destructiveness, and medication non-compliance. We conclude that it is possible to assess risk with measures that are available from shelter and medical records, and call for more research on the role of medication non-compliance in safety decisions and for longitudinal research to validate risk assessments.

Housing environments and community adjustment of severely mentally ill persons

This study examined relationships between the quality and appropriateness of housing environments and community adjustment of 729 deinstitutionalized severely mentally ill clients in a state-wide community support service program. Environmental measures included ratings of the physical condition of the client's residence, its adequacy for six key life activities, and the overall appropriateness of the residential setting for the client. Community adjustment measures included global level of functioning, degree of maladaptive behavior and client's perceived quality of life. Evidence is presented that quality and appropriateness of housing environments significantly affect aspects of client's community adjustment outcomes over a nine-month period.
