Risk factors for homelessness among US veterans

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 Trauma Treatment Outcomes Between Homeless and Housed Veterans in a VA PTSD Clinical Program

Homeless veterans are likely to experience Post Traumatic Stress Disorder (PTSD). Homelessness itself is traumatic, and PTSD may exacerbate homelessness risk for veterans. Often, PTSD goes untreated in this subpopulation of veterans. Our study examined trauma-focused treatment (TFT) and non-TFT initiation and completion in a sample of housed and homeless veterans being served by a PTSD clinical team in Washington, DC. Findings included a high percentage of veterans who experienced homelessness in the sample and lower treatment completion rates among homeless veterans compared to housed veterans. This difference was no longer significant when comparing only those veterans who engaged in treatment, reinforcing the critical role of treatment engagement in successful treatment completion across populations.

Journey to wellness: A socioecological analysis of veterans in recovery from substance use disorders

Substance use disorders are increasingly prevalent among veterans in the United States. Veterans in recovery face unique challenges, such as high rates of psychiatric comorbidities, difficulties adjusting to civilian life, and inadequate housing and mental health services. While prior research has explored veterans' experiences in recovery, studies have not implemented a multilevel perspective in their analyses. The current qualitative study examined how individual veteran experiences intersect with interpersonal and systemic factors. Semistructured focus groups were conducted with veterans who were former or current residents of recovery homes (N = 20). Thematic analysis was utilized to explore veterans' personal experiences through the CHIME-D framework (connectedness, hope & optimism, identity, meaning in life, empowerment, and difficulties). The data were further analyzed within a socioecological model (intrapersonal, interpersonal, and community). Each component of the CHIME-D framework was salient across all focus groups, with connectedness, empowerment, and difficulties being the most prominent themes that occurred across all socioecological levels. Results suggest that recovery initiatives can effectively assist veterans by promoting empowerment, facilitating social connections, and addressing cooccurring difficulties across multiple socioecological contexts. Additionally, treatment programs should encourage veterans to take on meaningful roles in their communities. Future research should continue to explore veterans' recovery experiences using a socioecological model.

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

OBJECTIVES

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

STUDY DESIGN

This was a nationally representative survey.

METHODS

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

RESULTS

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

CONCLUSION

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

Correlates of Incarceration History Among Military Veterans

Veterans with histories of incarceration are at greater risk for poor physical and mental health outcomes, yet prior research in this population has focused on specific subsets of veterans or a narrow range of predictors. We utilized the Bronfenbrenner Socioecological Model as the framework to evaluate correlates of incarceration history in a large sample of Iraq and Afghanistan-era veterans at four levels: demographic, historical, clinical, and contextual. Participants were 2,904 veterans (76.9% male; 49.5% White and 46.5% Black; mean age 38.08, SD = 10.33), 700 of whom reported a history of incarceration. Four logistic regression models predicting history of incarceration were tested, adding demographic, historical, clinical, and contextual variables hierarchically. In the final model, younger age (OR=0.99, 95% CI=0.98-1.00), male gender (OR of being female =0.28, 95% CI=0.21-0.38), belonging to a historically marginalized group (OR of being White =0.69, 95% CI=0.56-0.84), family history of incarceration (OR=1.47, 95% CI=1.10-1.94), adult interpersonal trauma (OR=1.39, 95% CI=1.28-1.51), problematic alcohol use (OR=1.03, 95% CI=1.02-1.05), drug abuse (OR=1.15, 95% CI=1.11-1.19), and unemployment (OR for being employed=0.76, 95% CI=0.62-0.92) were significantly associated with a history of incarceration. Implications of these findings for developing interventions and supporting systems to effectively target this high-risk population of veterans are discussed.

Socioeconomic challenges during the COVID-19 pandemic for Veterans with psychosis or recent homelessness

The COVID-19 pandemic and social distancing have directly impacted the socioeconomic well-being of most Americans. Veterans with psychosis (PSY) and Veterans who were recently housed (RHV) through a supportive housing programme may be especially vulnerable to experiencing negative socioeconomic effects of the pandemic. In this study, we investigated socioeconomic experiences and challenges during the pandemic in these two putatively vulnerable Veteran groups and in Veterans with no history of PSY or homeless (i.e., control Veterans, CTL). A total of 231 Veterans (81 PSY, 76 RHV, 64 CTL) participated in the baseline assessment, and 203 in the follow-up assessment (74 PSY, 63 RHV, 66 CTL). At both assessment points we obtained socioeconomic information, including personal finances, financial concerns, housing concerns, experience of material hardships, and employment status. All groups of Veterans reported socioeconomic challenges during the pandemic, but the pattern of effects differed across groups. Although RHV was in a similar position to the PSY group with respect to personal finances, they reported lower levels of financial well-being and were more prone to experiencing material hardships compared to the other two groups. CTL was most vulnerable to experiencing negative financial shocks. Contrary to expectations, PSY did not experience disproportionate material hardships compared to CTL. Veterans face significant socioeconomic challenges during the COVID-19 pandemic. However, RHV disproportionately experienced certain concerns and hardships, and these are a target for intervention by clinicians and service providers. PSY generally fared better than anticipated, possibly reflecting longstanding engagement with VA services that could serve to buffer the socioeconomic impact of the pandemic.

Longitudinal high-frequency ethnographic interviewing to simulate and prepare for intensive smartphone data collection among veterans with homeless experience

Objective

While Veteran homelessness has steadily declined over the last decade, those who continue to be unhoused have complex health and social concerns. Housing instability interferes with access to healthcare, social services, and treatment adherence. Preventing unwanted housing transitions is a public health priority. This study is the first phase of a larger research agenda that aims to test the acceptability and feasibility of smartphone-enabled data collection with veterans experiencing homelessness. In preparation for the development of the smartphone data collection application, we utilized ethnographic methods guided by user-centered design principles to inform survey content, approach to recruitment and enrollment, and design decisions.

Methods

We used a case study design, selecting a small sample (n = 10) of veterans representing a range of homelessness experiences based on risk and length of time. Participants were interviewed up to 14 times over a 4-week period, using a combination of qualitative methods. Additionally, 2 focus group discussions were conducted. Interviews were audio-recorded and transcribed. Data were synthesized and triangulated through use of rapid analysis techniques.

Results

All participants had experience using smartphones and all but one owned one at the time of enrollment. Participants described their smartphones as “lifelines” to social network members, healthcare, and social service providers. Social relationships, physical and mental health, substance use, income, and housing environment were identified as being directly and indirectly related to transitions in housing. Over the course of ~30 days of engagement with participants, the research team observed dynamic fluctuations in emotional states, relationships, and utilization of services. These fluctuations could set off a chain of events that were observed to both help participants transition into more stable housing or lead to setbacks and further increase vulnerability and instability. In addition to informing the content of survey questions that will be programmed into the smartphone app, participants also provided a broad range of recommendations for how to approach recruitment and enrollment in the future study and design features that are important to consider for veterans with a range of physical abilities, concerns with trust and privacy, and vulnerability to loss or damage of smartphones.

Conclusion

The ethnographic approach guided by a user-centered design framework provided valuable data to inform our future smartphone data collection effort. Data were critical to understanding aspects of day-to-day life that important to content development, app design, and approach to data collection.

Housing Outcomes of Adults Who Were Homeless at Admission to Substance Use Disorder Treatment Programs Nationwide

OBJECTIVE

Substance use disorders affect 30%-50% of single homeless adults, and specialized homelessness service programs enable homeless persons to exit homelessness at rates of about 80%. However, many such adults are treated in substance use disorder treatment programs. This study examined housing outcomes in these programs.

METHODS

Data from the Treatment Episode Data Set: Discharges database were used to examine housing status at discharge from substance use disorder treatment programs of adults who were homeless at admission. Associations of outcomes with sociodemographic characteristics, treatment programs and processes, and clinical variables were further evaluated with bivariate and multivariate logistic regressions. Odds ratios of ≥1.5 or ≤0.67 were considered meaningful.

RESULTS

Of 1,200,105 persons admitted to the programs, 192,838 (16.1%) were homeless at admission; 68.7% remained homeless at discharge, 16.3% were discharged to dependent housing, and only 15.0% were discharged to independent housing. Factors associated with remaining homeless included being age ≥55 years, being unemployed, admission for detoxification (vs. rehabilitation or residential treatment or ambulatory treatment), shorter stays, and program noncompletion. Factors associated with discharge to independent versus dependent housing included employment, admission to nonintensive outpatient treatment, and, unexpectedly, shorter stays.

CONCLUSIONS

Most adults experiencing homelessness at admission to substance use disorder treatment programs remained homeless at discharge, and only half of those no longer homeless were independently housed. These outcomes are considerably worse than outcomes typically reported by specialized homelessness service programs. Evidence-based service models that support exit from homelessness could be provided through augmented internal programming or links with specialized programs.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

Predicting Homelessness Among U.S. Army Soldiers No Longer on Active Duty

INTRODUCTION

The ability to predict and prevent homelessness has been an elusive goal. The purpose of this study was to develop a prediction model that identified U.S. Army soldiers at high risk of becoming homeless after transitioning to civilian life based on information available before the time of this transition.

METHODS

The prospective cohort study consisted of observations from 16,589 soldiers who were separated or deactivated from service and who had previously participated in 1 of 3 baseline surveys of the Army Study to Assess Risk and Resilience in Servicemembers in 2011-2014. A machine learning model was developed in a 70% training sample and evaluated in the remaining 30% test sample to predict self-reported homelessness in 1 of 2 Longitudinal Study surveys administered in 2016-2018 and 2018-2019. Predictors included survey, administrative, and geospatial variables available before separation/deactivation. Analysis was conducted in November 2020-May 2021.

RESULTS

The 12-month prevalence of homelessness was 2.9% (SE=0.2%) in the total Longitudinal Study sample. The area under the receiver operating characteristic curve in the test sample was 0.78 (SE=0.02) for homelessness. The 4 highest ventiles (top 20%) of predicted risk included 61% of respondents with homelessness. Self-reported lifetime histories of depression, trauma of having a loved one murdered, and post-traumatic stress disorder were the 3 strongest predictors of homelessness.

CONCLUSIONS

A prediction model for homelessness can accurately target soldiers for preventive intervention before transition to civilian life.

Comparing psychosocial functioning, suicide risk, and nonsuicidal self-injury between veterans with probable posttraumatic stress disorder and alcohol use disorder

BACKGROUND

Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) are each common among Unites States (U.S.) military veterans and frequently co-occur (i.e., PTSD+AUD). Although comorbid PTSD+AUD is generally associated with worse outcomes relative to either diagnosis alone, some studies suggest the added burden of comorbid PTSD+AUD is greater relative to AUD-alone than to PTSD-alone. Furthermore, nonsuicidal self-injury (NSSI) is more common among veterans than previously thought but rarely measured as a veteran psychiatric health outcome. This study sought to replicate and extend previous work by comparing psychosocial functioning, suicide risk, and NSSI among veterans screening positive for PTSD, AUD, comorbid PTSD+AUD, and neither disorder.

METHODS

This study analyzed data from a national sample of N = 1046 U.S. veterans who had served during the Gulf War. Participants self-reported sociodemographic, functioning, and clinical information through a mailed survey.

RESULTS

Veterans with probable PTSD+AUD reported worse psychosocial functioning across multiple domains compared to veterans with probable AUD, but only worse functioning related to controlling violent behavior when compared to veterans with probable PTSD. Veterans with probable PTSD+AUD reported greater suicidal ideation and NSSI than veterans with probable AUD, but fewer prior suicide attempts than veterans with probable PTSD.

LIMITATIONS

This study was cross-sectional, relied on self-report, did not verify clinical diagnoses, and may not generalize to veterans of other military conflicts.

CONCLUSIONS

Findings underscore the adverse psychiatric and functional outcomes associated with PTSD and comorbid PTSD+AUD, such as NSSI, and highlight the importance of delivering evidence-based treatment to this veteran population.

Qualitative findings from a Housing First evaluation project for homeless Veterans in Canada

LAY SUMMARY

This two-year study implemented a Housing First approach among homelessness services for Veterans in four cities across Canada (Victoria, Calgary, London, and Toronto). This approach included peer support and harm reduction resources for Veterans. To obtain a detailed evaluation of personal experiences and opinions, focus groups were held with Veterans, housing staff, and stakeholders at three time points during the study: July-September 2012, May-June 2013, and January 2014. Harm reduction and peer support were regarded as positive aspects of this new approach to housing and homelessness. It was suggested that greater mental health support, support from peers with military experience, and issues regarding roommates should be considered in future implementations of housing services for Veterans. It was also noted that to support personal stabilization, permanent housing is preferred over transitional or temporary housing. Future housing programs serving Veterans experiencing homelessness should consider the addition of harm reduction and peer support to further enhance services and help maintain housing stability.

Telehealth Utilization Is Associated with Lower Risk of Discontinuation of Buprenorphine: a Retrospective Cohort Study of US Veterans

OBJECTIVE

Treatment for opioid use disorder (OUD) may include a combination of pharmacotherapies (such as buprenorphine) with counseling services if clinically indicated. Medication management or engagement with in-person counseling services may be hindered by logistical and financial barriers. Telehealth may provide an alternative mechanism for continued engagement. This study aimed to evaluate the association between telehealth encounters and time to discontinuation of buprenorphine treatment when compared to traditional in-person visits and to evaluate potential effect modification by rural-urban designation and in-person and telehealth combination treatment.

METHODS

A retrospective cohort study of Veterans diagnosed with OUD and treated with buprenorphine across all facilities within the Veterans Health Administration (VHA) between 2008 and 2017. Exposures were telehealth and in-person encounters for substance use disorder (SUD) and mental health, treated as time-varying covariates. The primary outcome was treatment discontinuation, evaluated as 14 days of absence of medication from initiation through 1 year.

RESULTS

Compared to in-person encounters, treatment discontinuation was lower for telehealth for SUD (aHR: 0.69; 95%CI: 0.60, 0.78) and mental health (aHR: 0.69; 95%CI: 0.62, 0.76). There was no evidence of effect modification by rural-urban designation. Risk of treatment discontinuation appeared to be lower among those with telehealth only compared to in-person only for both SUD (aHR: 0.48, 95%CI: 0.37, 0.62) and for mental health (aHR: 0.46; 95%CI: 0.33, 0.65).

CONCLUSIONS

As telehealth demonstrated improved treatment retention compared to in-person visits, it may be a suitable option for engagement for patients in OUD management. Efforts to expand services may improve treatment retention and health outcomes for VHA and other health care systems.

Psychosocial Barriers and Their Impact on Hepatocellular Carcinoma Care in US Veterans: Tumor Board Model of Care

BACKGROUND

Psychosocial barriers, including low socioeconomic status, homelessness, alcohol and substance use disorders, and psychiatric disorders are prevalent in US veterans. Our study aims to identify the prevalence of psychosocial barriers in veterans diagnosed with hepatocellular carcinoma (HCC), and their impact on receipt of cancer care.

METHODS

A retrospective cohort study was performed of all veterans diagnosed with HCC at the William S. Middleton Memorial Veterans' Hospital in Madison, Wisconsin, whose tumor care was coordinated through a multidisciplinary tumor board. Outcomes included receipt of any HCC-specific therapy and overall survival.

RESULTS

From January 1, 2007, through December 31, 2016, 149 veterans were diagnosed with HCC. Substance use disorders were reported in 124 (83%) patients, psychiatric illness was documented in 55 (37%) patients, 23 (15%) patients had incomes below the poverty threshold, and 7 (5%) were experiencing homelessness. The mean (SD) distance traveled for care was 207.1 (277.9) km; travel and lodging assistance were accessed by 50 (34%) and 33 (22%) veterans, respectively. Seventy-one patients (48%) had HCC exceeding T2 stage at diagnosis. Curative treatment was offered to 78 (52%) patients, with 127 (85%) receiving any HCC-specific care. Median survival from diagnosis was 727 days (95% CI, 488-966).

CONCLUSIONS

Psychosocial barriers were common in our veteran cohort. Individualizing care, and coordination of travel and lodging, assisted in enabling high rates of receipt of HCC-specific therapy and improving patient survival.

Unstable Housing and Kidney Disease: A Primer

Stable housing is essential for health. Over 580,000 Americans experienced homelessness during one night in 2020, and over 37 million households spend over 30% of their income on housing. Unstable housing has been associated with mortality, acute care utilization, communicable and non-communicable diseases, a higher risk of kidney disease, and kidney disease progression. In this review, we define various forms of unstable housing, provide an overview of the interaction between unstable housing and health, and discuss existing evidence associating housing and kidney disease. We provide historical context for unstable housing in the United States, and detail policy, community, and individual-level factors that contribute to the risk of unstable housing. Unstable housing likely affects kidney health via a complex interplay of individual and structural factors. Various screening tools are available for use by providers. Special considerations should be made when working with individuals experiencing unstable housing to meet their unique needs, facilitate health care engagement, and optimize outcomes. Housing interventions have been shown to improve outcomes and should be examined for their role in kidney disease.

Permanent Supportive Housing With Housing First: Findings From a Community Guide Systematic Economic Review

INTRODUCTION

The annual economic burden of chronic homelessness in the U.S. is estimated to be as high as $3.4 billion. The Permanent Supportive Housing with Housing First (Housing First) program, implemented to address the problem, has been shown to be effective. This paper examines the economic cost and benefit of Housing First Programs.

METHODS

The search of peer-reviewed and gray literature from inception of databases through November 2019 yielded 20 evaluation studies of Housing First Programs, 17 from the U.S. and 3 from Canada. All analyses were conducted from March 2019 through July 2020. Monetary values are reported in 2019 U.S. dollars.

RESULTS

Evidence from studies conducted in the U.S. was separated from those conducted in Canada. The median intervention cost per person per year for U.S. studies was $16,479, and for all studies, including those from Canada, it was $16,336. The median total benefit for the U.S. studies was $18,247 per person per year, and it was $17,751 for all studies, including those from Canada. The benefit-to-cost ratio for U.S. studies was 1.80:1, and for all studies, including those from Canada, it was 1.06:1.

DISCUSSION

The evidence from this review shows that economic benefits exceed the cost of Housing First Programs in the U.S. There were too few studies to determine cost-benefit in the Canadian context.

Psychosocial well-being among veterans with posttraumatic stress disorder and substance use disorder

OBJECTIVE

Concurrent posttraumatic stress disorder and substance use disorder (PTSD/SUD) in U.S. military veterans represents an urgent public health issue associated with significant clinical challenges. Although previous research has shown that veterans with PTSD/SUD endorse more psychosocial risk factors and fewer protective factors than veterans with neither or only one of these disorders, no study has applied a comprehensive framework to characterize the vocational, financial, and social well-being of veterans with PTSD/SUD. Furthermore, it is not fully known how well-being among veterans with PTSD/SUD compares to that of veterans with posttraumatic stress disorder (PTSD) only, substance use disorder (SUD) only, or neither disorder.

METHOD

This cross-sectional observational study analyzed data from the National Post-Deployment Adjustment Survey, which recruited a random national sample of U.S. veterans who served on/after September 11, 2001. Participants (weighted N = 1,102) self-reported sociodemographic, clinical, and military background information in addition to aspects of their vocational, financial, and social well-being.

RESULTS

Veterans with PTSD/SUD were particularly likely to report lifetime experiences of homelessness, violent behavior, suicidal ideation, and suicide attempts. Veterans with PTSD/SUD reported worse social well-being than the PTSD-only, SUD-only, and neither-disorder groups. They also reported worse vocational and financial well-being than veterans with SUD only or with neither disorder but did not significantly differ from the PTSD-only group on vocational or financial well-being.

CONCLUSIONS

The findings underscore the importance of assessing multiple aspects of well-being in veterans with PTSD and/or SUD. The findings also point to promising treatment targets to improve psychosocial functioning and overall quality of life among veterans with PTSD and/or SUD.

Establishing a Research Agenda for Suicide Prevention Among Veterans Experiencing Homelessness

Suicide among Veterans experiencing or at risk for homelessness remains a significant public health concern. Conducting research to understand and meet the needs of this at-risk population remains challenging due to myriad factors (e.g., clinical complexity including multimorbidity, difficulty monitoring risk across systems). To address this challenge, the United States Department of Veterans Affairs (VA) convened the Health Services Research and Development (HSR&D) Suicide Prevention in Veterans Experiencing Homelessness: Research and Practice Development meeting, bringing together subject-matter experts in the fields of homelessness and suicide prevention, both from within and outside of VA. During the meeting, attendees identified 10 potential research priorities at the intersection of suicide prevention and homelessness. After the meeting, Delphi methodology was used to achieve consensus on the relative importance of the identified research domains. Through this iterative Delphi process, agreement was reached regarding the need to increase understanding of barriers and facilitators to suicide risk assessment and emergency intervention for Veterans experiencing homelessness by examining the perspectives of both Veterans and healthcare providers. Elucidating the complex relationships between risk periods, subgroups, suicide means, and drivers of suicide among Veterans experiencing homelessness was also considered a top priority. This article documents the Delphi process and provides a research agenda for researchers, funding agencies, and policymakers to prioritize the most relevant and potentially impactful research domains aimed at preventing suicide among Veterans experiencing or at risk for homelessness.

Problematic anger and economic difficulties: Findings from the Millennium Cohort Study

BACKGROUND

The role of problematic anger in relation to economic difficulties is not well understood. This study examined the association of problematic anger with 4 elements of economic difficulties among service members and veterans.

METHODS

Study participants (n = 95,895) were from the Millennium Cohort Study, and included U.S. service members and veterans; analyses were restricted to a Reserve/National Guard and/or veteran sample as appropriate. Key measures included the Dimensions of Anger Reactions scale and self-reported economic variables (involuntary job loss, financial problems, unemployment and homelessness). Covariates included demographics, military characteristics, disabling injury or illness, problem drinking, posttraumatic stress disorder, and major depressive disorder. The study design was cross-sectional.

RESULTS

Among all participants, 17.4% screened positive for problematic anger, 29.7% reported involuntary job loss, and 6.4% reported financial problems. After adjustment for covariates, problematic anger was associated with involuntary job loss (AOR=1.28; 95% CI: 1.22, 1.33) and financial problems (AOR=1.46; 95% CI: 1.36, 1.57). Among veterans, 12.1% reported being unemployed; among Reserve/National Guard and veterans, 2.3% reported homelessness. Problematic anger was associated with unemployment (AOR=1.28, 95% CI: 1.18, 1.37) and homelessness (AOR=1.33; 95% CI: 1.16, 1.52) after adjusting for covariates.

LIMITATIONS

The study relied on self-report data and directionality could not be established.

CONCLUSIONS

Problematic anger was significantly associated with involuntary job loss, financial problems, unemployment and homelessness, even after adjusting for relevant covariates. These findings have clinical relevance in demonstrating the potential for targeting problematic anger in service members and veterans.

Actuarial prediction versus clinical prediction of exits from a national supported housing program

The accurate identification of persons at risk of exiting permanent supportive housing could help maximize client success and minimize attrition and premature exits from such housing. Thus, in the present study, we developed and tested multivariable prediction models of negative and positive exits from the U.S. Department of Housing and Urban Development-Veterans Affairs Supportive Housing (HUD-VASH) program using logistic regression and random forests. We compared the performance of these models with clinical predictions made by HUD-VASH program case managers. We selected a cohort of all 92,196 Veterans who entered HUD-VASH nationwide between October 1, 2014 and September 30, 2019, 70% of whom were randomly selected to serve as the development cohort and the remaining 30% of whom served as the validation cohort. Negative and positive exits were measured until September 30, 2019. A subset of 1,264 Veterans was used to compare performance of models with clinical judgment. Predictor variables included sociodemographic characteristics, health and behavioral health diagnoses, homeless/housing history, and VA service utilization history. Performance of models and clinical judgment were assessed using an array of metrics including area under the receiver operating characteristic curve (AUROC), sensitivity, specificity, and positive predictive value. The logistic regression and random forest models had similar, modest performance in predicting negative and positive exits. These models were substantially more sensitive, yet far less specific in predicting exits than clinician ratings. Study findings highlight the challenges and tradeoffs in using actuarial models or case manager predictions to target interventions to Veterans at risk of exiting HUD-VASH.

Social isolation and well-being in veterans with mental illness

BACKGROUND

Veterans with mental illness are a growing population in the United States (US). For some veterans, their military service has a negative effect on well-being. Social isolation is problematic for veterans' mental health by increasing incidence of depression, suicidal ideation or attempts, and readmittance to psychiatric hospitals. Social support is a protective factor for individuals with mental illness and is key to a successful military-to-civilian transition.

AIM

Thus, we examine the relationship of social isolation on well-being among veterans with any mental illness.

METHODS

This cross-sectional correlational study consisted of a sample of 146 US veterans with any mental illness. A three-step hierarchical regression analysis was used to determine if social isolation is a predictor of well-being after controlling for demographics, functional limitations and depression.

RESULTS

Findings revealed social isolation was positively correlated with functional limitations (r = 0.48, p < 0.001), depression (r = 0.66, p < 0.001) and negatively correlated with well-being (r = -.64, p < 0.001). Hierarchical regression analysis revealed social isolation was negatively correlated (β = -.44, p < 0.001) with well-being. Overall, our three-step model accounted a total of 50% of variance in well-being, a large effect size.

CONCLUSION

The findings underscore the importance of assessing the relationship of social isolation on well-being in veterans with mental illness. The findings also highlight promising targets to improve prevention and psychosocial interventions to improve well-being among veterans with mental illness.

Understanding the Intersection of Homelessness and Justice Involvement: Enhancing Veteran Suicide Prevention Through VA Programming

BACKGROUND

Veterans with a history of homelessness and justice involvement are at greater risk for mental health sequelae, including suicide.

OBSERVATIONS

A bidirectional relationship exists between criminal justice involvement and housing instability (ie, the institutional circuit). Homelessness and justice involvement often represent a vicious cycle that is difficult to escape. The US Department of Veterans Affairs (VA) has a number of programs focused on connecting homeless and justice-involved veterans to health and social services. This paper reviews existing programing and initiatives within such services to detect risk for suicide and connect these veterans to appropriate evidence-based mental health care.

CONCLUSIONS

The VA currently has several programs focused on enhancing care for homeless and justice-involved veterans, many of which currently incorporate suicide prevention initiatives. Understanding of factors that may impact health service delivery of suicide risk assessment and intervention may be beneficial in order to enhance veteran suicide prevention efforts.

Homelessness and publicly funded substance use disorder treatment in California, 2016-2019: Analysis of treatment needs, level of care placement, and outcomes

INTRODUCTION

Both homelessness and substance use have increased in recent years. People experiencing homelessness (PEH) are at increased risk for health problems and early mortality, both of which can be exacerbated by substance use disorders (SUD). Specialty SUD treatment is likely needed to address substance use among PEH, and more than 232,000 PEH received treatment from U.S. publicly funded SUD programs in 2015. The objective of this paper is to develop a better understanding of the SUD services that PEH receive in publicly funded treatment programs by (1) describing the characteristics and needs of the PEH population served in publicly funded SUD treatment programs, compared to non-PEH populations; (2) determining if differences exist in treatment placement (level of care) for PEH and non-PEH; and (3) gauging how successful programs are in treating PEH compared to non-PEH.

METHODS

Observational study using a two-way fixed effect model to determine associations among homelessness, retention, and outcomes among Medicaid beneficiaries receiving SUD treatment in California from 2016 to 2019 (n = 638,953). The study team used ordinary least squares (OLS) regression to measure the degree to which homelessness was associated with baseline characteristics, SUD services received, and treatment outcomes.

RESULTS

PEH were significantly more likely than non-PEH to be having methamphetamine or heroin as their primary substance. PEH had greater frequency of primary substance use prior to entering treatment, greater ER and hospital utilization, more criminal justice involvement, and greater prevalence of mental health diagnoses and unemployment. PEH were 9.82% more likely than non-PEH to receive residential treatment and 7.11% less likely than non-PEH to receive treatment intensive outpatient modalities. Homelessness was associated with an 11.90% decrease in retention, and a 19.40% decrease in successful discharge status. These trends were consistent across outpatient, intensive outpatient, and residential modalities.

CONCLUSIONS

Developing SUD treatment capacity and housing supports can improve treatment outcomes for PEH. Potential strategies to improve SUD services for PEH include providing more contingency management, opioid pharmacotherapies, programming designed to treat individuals with co-occurring mental health disorders, and resources for housing options that can support PEH in their recovery.

Twenty-year trends in use of electroconvulsive therapy among homeless and domiciled veterans with mental illness

BACKGROUND

To examine socioeconomic disparities in use of electroconvulsive therapy (ECT) among homeless or unstably housed (HUH) veterans with mental illness.

METHODS

National data from medical records in years 2000 to 2019 on 4 to 6 million veterans with mental illness, including 140 000 to 370 000 homeless veterans served annually from the U.S. Department of Veterans Affairs (VA) healthcare system, were analyzed to examine ECT utilization and changes in utilization over time.

RESULTS

ECT utilization was higher among HUH veterans (58-104 per 1000) than domiciled veterans with mental illness (9-15 per 1000) across years with a trend toward increasing use of ECT use among HUH veterans over time. Among HUH and domiciled veterans who received ECT, veterans received an average of 5 to 9 sessions of ECT. There were great regional differences in rates of ECT utilization among HUH and domiciled veterans with the highest overall rates of ECT use at VA facilities in the Northeast and Northwest regions of the country.

DISCUSSION

ECT is commonly and safely used in HUH veterans in a comprehensive healthcare system, but geographic and local factors may impede access to ECT for veterans who may benefit from this treatment. Efforts should be made to reduce barriers to ECT in the HUH population.

Association of lifetime homelessness and justice involvement with psychiatric symptoms, suicidal ideation, and suicide attempt among post-9/11 veterans

Both homelessness and criminal justice involvement can impact mental health symptoms and increase risk for suicide. Despite this, few studies have examined their cumulative impact. Moreover, no studies to date have examined the impact of these social determinants of health on post-9/11 veterans, a population with high rates of housing insecurity and justice involvement. The current study sought to better understand the adverse impacts of homelessness and justice involvement on mental health symptoms and suicide risk among post-9/11 veterans. We carried this out by conducting a secondary analysis of cross-sectional data from a 2018 national survey of men and women post-9/11 veteran users and non-users of Veterans Health Administration (VHA) services (N = 15,067). Gender-stratified Poisson and multivariate regressions examined mental health symptoms and suicide risk based on history of homelessness and justice involvement. Models adjusted for sociodemographics, military-related variables, and trauma exposure. Homelessness and justice involvement were both independently associated with more severe posttraumatic, depressive, and substance use symptoms as well as increased rates of suicidal ideation and attempt relative to those with no history of homelessness or justice involvement. Veterans with a history of both homelessness and justice involvement reported the most severe mental health symptoms and suicide risk. This study found consistent positive associations with mental health symptoms for homelessness and justice-involved veterans. Enhancing and increasing access to services that address complex mental health presentation among those with histories of justice involvement and housing instability remain necessary.

Hepatitis C virus care cascade in persons experiencing homelessness in the United States in the era of direct-acting antiviral agents: A scoping review

The hepatitis C virus (HCV) care cascade has been well characterized in the general United States population and other subpopulations since curative medications have been available. However, information is limited on care cascade outcomes in persons experiencing homelessness. The main objective of this study was to map the available evidence on HCV care cascade outcomes in people experiencing homelessness in the U.S. in the era of direct-acting antiviral agents (DAAs). Primary and secondary outcomes included linkage to care (evaluation by a provider that can treat HCV) and sustained virologic response (SVR) or cure. Exploratory outcomes included other cascade data, like treatment initiation, which precedes SVR. PubMed was the primary database accessed for this scoping review. We characterized the HCV care cascade in people experiencing homelessness using sources of evidence published in 2014 onwards that reported the proportions of persons who were linked to care, achieved SVR, and completed other cascade steps. We synthesized our results into a scoping review. The proportion of persons linked to care among chronically infected cohorts with unstable housing ranged from 29.3% to 88.7%. Among those chronically infected, 5%-58.8% were started on DAAs and 5%-50% achieved SVR. In conclusion, these results show that persons experiencing homelessness achieve high rates of linkage to care in non-specialist community-based settings compared to the general U.S. population pre-DAAs. However, DAA initiation was found to be a rate-limiting step along the care cascade, resulting in commensurate low rates of cure.

Out of the trenches; prevalence of Australian veterans among the homeless population and the implications for public health

OBJECTIVES

To examine the prevalence of Australian Defence Force veterans among people sleeping rough and explore their health and social needs relative to non-veteran rough sleepers.

METHOD

Analysis of responses to the Vulnerability Index - Service Prioritisation Decision Assistance Tool (VI-SPDAT) collected from 8,027 rough sleepers across five Australian States from 2010-2017.

RESULTS

Veterans were found to comprise 5.6% of people sleeping rough in Australia, with veterans reporting having spent an average of 6.3 years on the street or in emergency accommodation (compared with an average of five years for their non-veterans counterparts). Veterans had a higher prevalence of self-reported physical health, mental health and social issues compared with non-veteran rough sleepers.

CONCLUSIONS

This is the first study of its kind to elucidate the presence of Australian veterans among people sleeping rough. That they are likely to have spent more years on the street, and have a higher prevalence of health and social issues, highlights the imperative for earlier intervention and prevention of veteran homelessness itself, and its health impacts. Implications for public health: Veteran homelessness has been comparatively hidden in Australia compared to other countries, and consequently the myriad of health, psychosocial and adjustment issues faced by homeless veterans has also been hidden. With heightened attention on veteran suicide and self-harm, earlier intervention to prevent veterans becoming homeless constitutes sound public health prevention and mental health policy.

Clinically significant substance use and residential stability among homeless or vulnerably housed persons in Canada: a longitudinal cohort study

BACKGROUND

We examined clinically significant substance use among homeless or vulnerably housed persons in three Canadian cities and its association with residential stability over time using data from the Health and Housing in Transition study.

METHODS

In 2009, 1190 homeless or vulnerably housed individuals were recruited in three Canadian cities and followed for 4 years. We collected information on housing and incarceration history, drug and alcohol use, having a primary care provider at baseline and annually for 4 years. Participants who screened positive for substance use at baseline were included in the analyses. We used a generalized logistic mixed effect regression model to examine the association between clinically significant substance use and residential stability, adjusting for confounders.

RESULTS

Initially, 437 participants met the criteria for clinically significant substance use. The proportion of clinically significant substance use declined, while the proportion of participants who achieved residential stability increased over time. Clinically significant substance use was negatively associated with achieving residential stability over the 4-year period (AOR 0.7; 95% CI 0.57, 0.86).

CONCLUSIONS

In this cohort of homeless or vulnerably housed individuals, clinically significant substance use was negatively associated with achieving residential stability over time, highlighting the need to better address substance use in this population.

Food Insecurity in US Military Veterans

BACKGROUND

Food insecurity (FI) is an important public health issue for US veterans. For many veterans, civilian life is fraught with service-incurred health issues and socioeconomic challenges, each risk factors for FI. The FI literature on veterans is limited due to insufficient coverage of the topic's complexity and the methods used to study it in this population. No published analysis has evaluated how FI has been examined in US veterans.

OBJECTIVES

We assessed how FI has been examined in US military veterans by identifying (1) the major content areas, or domains, studied in association with FI and (2) the existing research gaps.

METHODS

A scoping literature review was conducted to map the main research domains of the FI literature and identify knowledge gaps. Electronic database and hand searches identified potentially relevant studies (n = 61). Data extraction, utilizing a standardized set of design parameters, was completed. Duplicate removal and application of inclusion/exclusion criteria resulted in the studies (n = 21) selected for critical review.

RESULTS

Eight research domains were determined: FI prevalence, health status, dietary practices, health care utilization, economic instability, homelessness/housing instability, food program participation, and community/emergency preparedness-the most dominant was health status and the least dominant were social determinants (ie, homelessness/housing instability, food program participation). Research on validity and usability of FI assessment methods in veterans was virtually absent. Military service factors, longitudinal effects, FI among women, intervention effectiveness, and other areas lacked sufficient inquiry.

CONCLUSION

Research is required on lesser examined content areas and methodology to optimize surveillance and policy for veteran FI.

Association of the Military Transition to an All-Volunteer Force and Subsequent Zero-Tolerance Drug Policy with Characteristics of Male Veterans in the Vietnam, Post-Vietnam and Subsequent Post-Post Vietnam Cohorts

In the 1970s, following the Vietnam Conflict, the U.S. military transitioned to an All-Volunteer Force (AVF). In the 1980's military benefits increased and a zero-tolerance policy for illicit drugs was instituted. Changes in characteristics of veterans deserve study. National survey data from 2012 to 2013 compare vetderan-non-veteran differences in three age cohorts: the Vietnam cohort; the AVF (Post-Vietnam) cohort; and volunteers under the no tolerance policy (Post-Post-Vietnam). Comparisons addressed socio-demographic, behavioral, and substance use and psychiatric diagnoses. Multivariate interaction analyses between veteran status and age cohorts were used to identify significant veteran-non-veteran differences between the first and second, and second and third cohorts. Significant interactions showed that veteran-non-veteran comparisons for the Post-Vietnam cohort as compared to Vietnam cohort reveal later veterans to be relatively more likely to be black, disabled, with lower incomes, less health insurance, more homelessness, incarceration, and suicide attempts with greater substance use diagnosis. In contrast interactions show veteran-non-veteran comparisons for the Post-Post-Vietnam cohort as compared to Post-Vietnam cohort were less likely to be black, more likely to be married, retired, with incomes over $40,000, more education and private health insurance. They were less likely to have been homeless, incarcerated or to have made suicide attempts. The veteran cohort serving in the first years of the AVF showed significant socio-economic and behavioral disadvantage (e.g homelessness) compared to their predecessors while their successors, under no tolerance drug policy, showed reversal of these trends. Military recruitment and disciplinary policies significantly affect veteran economic and health status.

Longitudinal study of the housing and mental health outcomes of tenants appearing in eviction court

PURPOSE

Millions of people are evicted from rental properties in the U.S. annually, but little is known about them and their mental health. This study followed a cohort of eviction court participants over time and assessed their housing and mental health outcomes.

METHODS

One hundred and twenty-one tenants were recruited from an eviction court in New Haven, Connecticut, and their housing, mental health, and psychosocial status were assessed at baseline, 1, 3, 6, and 9 months following their encounter with the court. Inverse probability weighting was used for missing data.

RESULTS

At baseline, 42% of participants had appeared in eviction court before, 28% had experienced eviction, and 44% had been previously homeless. In addition, 39% screened positive for generalized anxiety disorder, 37% for posttraumatic stress disorder, 33% for major depressive disorder, and 17% reported suicidal ideation. At follow-up, participants experienced increased days of housing instability and homelessness over time with some persistent mental health symptoms. Less than one-quarter of participants received any mental health treatment during the 9-month follow-up period. About 54% of participants followed reported that they had to change their residence after their court appearance consistent with court records. Participants who had an eviction-related move experienced greater housing instability over time than participants who did not.

CONCLUSION

Together, these findings suggest that there is a sizable subgroup of adults who present to eviction court with persistent housing and mental health issues who do not receive adequate assistance in addressing these issues.

Understanding and Addressing the Unique Challenges and Conditions of the Veteran: Improving Sleep and Well-Being

Veterans are those who have served our country in one of the branches of armed forces or military reserves. The Veterans Health Administration is the largest integrated health system in the nation, providing health care services and latest research for veterans. Non-Veteran Health Administration primary care clinicians, who also take care of veterans, deserve to have an understanding of the unique challenges and conditions these individuals face and the resources that are available to improve sleep health and well-being of all veterans. This article guides these clinicians to manage sleep disorders, mental health disorders, and substance use among veterans.

Health Determinants among North Americans Experiencing Homelessness and Traumatic Brain Injury: A Scoping Review

Traumatic brain injury (TBI) in those experiencing homelessness has been described in recent literature as a contributor to increased morbidity, decreased functional independence, and early mortality. In this systematically conducted scoping review, we aimed to better delineate the health determinants-as defined by Health Canada/Centers for Disease Control and Prevention (CDC)-associated with TBI in North Americans experiencing homelessness. BIOSIS, MEDLINE, CINAHL, EMBASE, SCOPUS, and Global Health were searched from inception to December 30, 2020. Gray literature search consisted of relevant meeting proceedings. A two-step process was undertaken, assessing title/abstract and full articles, respectively, based on inclusion/exclusion criteria, leading to the final 20 articles included in the review. Data were abstracted, assessing the aims, literature quality, and bias. Five health determinants displayed strong associations with TBI in those North Americans experiencing homelessness, including male gender, poor physical environment, negative personal health behaviors, adverse childhood experiences (ACEs), and low educational attainment. In those studies displaying a comparator population experiencing homelessness without TBI, the TBI group displayed trends toward increased disparity in Health Canada and CDC defined health determinants. Most studies suffered from moderate limitations. There are associations between male gender, poor physical environment, negative personal health behaviors, ACEs, and limited education in those experiencing homelessness and TBI. The results suggest that those experiencing homelessness with TBI in North America suffer poorer health consequences than those without TBI. Future research on TBI in North Americans experiencing homelessness should focus on health determinants as potential areas for intervention, which may lead to improved outcomes for those experiencing both homelessness and TBI.

Housing and Social Connection: Older Formerly Homeless Veterans Living in Subsidized Housing and Receiving Supportive Services

Objectives: The purpose of this study was to (Aim 1) describe United States military veterans' experiences and attitudes about project-based housing (PBH) and tenant-based housing (TBH), including perceptions of their new environment, self-sufficiency, and social integration. We identified (Aim 2) features of program design and housing facilities associated with self-sufficiency and social integration including describing differences in veterans' experiences of housing (PBH vs. TBH).Methods: Interviews were conducted with 30 Veterans in the U.S. Department of Housing and Urban Development-VA Supportive Housing (HUD-VASH) program (25 male and 5 female; average age 63). Thirteen lived in PBH and 17 in TBH in the Greater Boston Metro Area.Results: Social isolation may be a particular challenge of older formerly homeless adults. Veterans in both types of supportive housing struggled with social isolation despite social engagement opportunities available in PBH. Healthcare and transportation issues were important for veterans living in TBH while behavioral health issues were a major factor for those living in both types of housing. Both groups of veterans relied on their case management teams as a means of support and social engagement.Conclusions: To reduce social isolation and loneliness, more attention is needed by program staff to provide varied social engagement opportunities, from one-on-one to group activities.Clinical Implications: These findings can help providers recognize issues inhibiting formerly homeless veterans from being successful in supportive housing. Clinicians should consider how veterans' behavioral health impacts their ability to engage in social activities. Substance use disorder remains a challenge for many veterans interviewed. Its effects impact their perceptions of fellow residents, perceptions of housing, and recovery.

Trauma-related differences in socio-emotional functioning predict housing and employment outcomes in homeless veterans

RATIONALE

Mental health and substance use disorders are strong risk factors for homelessness. Understanding the role of transdiagnostic factors could help inform efforts to reduce homelessness among veterans with a range of disorders. Homeless veterans have high rates of trauma exposure, which can result in the depletion of social and emotional resources that may contribute to housing and employment stability. In this study, we evaluated the role of problems with emotional lability and interpersonal closeness as transdiagnostic socio-emotional factors that might interfere with efforts to achieve housing and employment stability.

METHODS

The sample consisted of 346 homeless veterans with co-occurring disorders that were admitted to a U.S. Department of Veterans Affairs (VA) residential treatment program between 2004 and 2009. Assessments were conducted at treatment entry (baseline) and two follow-up timepoints (6- and 12-months). Variables used in the current analyses included history of interpersonal trauma exposure, emotional lability and interpersonal closeness at baseline and 6-months, and homelessness and employment problems during follow-up. Data were analyzed using structural equation modeling and counterfactually-defined mediation effects.

RESULTS

Veterans exposed to more trauma types experienced more baseline impairment and less improvement during treatment in emotional lability and interpersonal closeness. Problems with interpersonal closeness mediated 73% of the relationship between exposure to multiple traumas and homelessness, and 32%-61% of the relationship between trauma exposure and employment problems. Emotional lability mediated 36% of the relationship between exposure to multiple traumas and employment problems. Decomposition of indirect pathways revealed that indirect effects were primarily transmitted through changes during treatment, and not baseline levels.

CONCLUSION

Findings support a cumulative effect of trauma on persistence of socio-emotional deficits across treatment, which increased risk of homelessness and employment problems during follow-up. Greater attention and more targeted efforts should be directed at helping trauma-exposed veterans build socio-emotional resources during treatment.

The association of opioid use disorder and homelessness nationally in the veterans health administration

BACKGROUND

Substance use disorder (SUD) is a major risk factor for homelessness, but the specific association of opioid use disorder (OUD) and homelessness in the context of their shared risk factors has not been the focus of prior studies. We used national data from the United States Veterans Health Administration (VHA) to examine the association of OUD and homelessness in the context of shared risk factors.

METHODS

In this cross-sectional analysis of veterans who received VHA care during Fiscal Year 2012 (N = 5,450,078), we compared the prevalence of OUD and other sociodemographic, and clinical factors among homeless and non-homeless veterans. We estimated the odds ratio for homelessness associated with OUD alone, and after adjusting for other factors through multivariate logistic regression.

RESULTS

Homeless veterans had substantially higher prevalence of OUD than other VHA patients (7.7 % Vs 0.6 %) and OUD was associated with 13 times higher unadjusted odds of homelessness (Odds Ratio [OR] 13.36, 95 % CI 13.09-13.62), which decreased with adjustment for sociodemographic factors (black race, mean income and age), other SUD, medical, and psychiatric diagnoses (final OR 1.57, 95 % CI 1.53-1.61). Other SUDs (alcohol, cannabis, cocaine, and hallucinogens) showed similar or slightly higher odds of homelessness as OUD in the final model.

CONCLUSIONS

OUD was strongly associated with homelessness among US veterans although this association was largely but not entirely attenuated by shared sociodemographic and co-morbid risk factors including several other SUDs. Treatment of homeless veterans with OUD should address socio-economic vulnerabilities and other co-morbidities in addition to treatments for OUD.

Mindfulness-Based Relapse Prevention for the Treatment of Gambling Disorder among U.S. Military Veterans: Case Series and Feasibility

Gambling disorder (GD) occurs at higher rates in U.S. veterans than civilians. The present case series describes the application of a manualized mindfulness treatment used with U.S. veterans seeking outpatient treatment for GD at a Department of Veterans Affairs hospital. Mindfulness-Based Relapse Prevention (MBRP) was developed to treat substance use disorders, but its core principles can be readily applied to the treatment of behavioral addictions. However, there has been little empirical evidence demonstrating its successful application for GD, and none demonstrating its successful implementation with U.S. veterans. Three veterans receiving treatment for GD participated in a 9-session adapted MBRP protocol. Following completion of treatment, the veterans reported less frequent engagement in their gambling behavior, fewer cravings, and less intense craving. The veterans also experienced increased self-efficacy in managing urges, less impulsivity and emotion dysregulation, and improved functioning. Preliminary results provide support for a larger treatment trial for veterans seeking treatment for GD.

Gender as a moderator of the association of military sexual trauma and posttraumatic stress symptoms

OBJECTIVE

The current study examined the moderating role of gender on the association of military sexual trauma (MST) type (harassment-only vs. assault) and posttraumatic stress symptoms (PTSS) using the 6-factor Anhedonia Model.

METHODS

Participants were 1321 service members/veterans. Two-part hurdle models assessed the moderating role of gender on the association of MST type with the presence (at least "moderate" symptoms endorsed within each cluster) or severity of PTSS and symptom clusters.

RESULTS

Among those who experienced assault MST, women were at higher risk for the presence of intrusive, avoidance, negative affect, and anhedonia symptoms, and higher risk for more severe negative affect symptoms. Among those who experienced harassment-only MST, men were at higher risk of more severe PTSS symptoms overall and in the intrusive and dysphoric arousal symptom clusters. No other significant differences were observed.

CONCLUSIONS

Gathering information on MST type may be helpful in treatment planning.

Mental health and addiction service use among United States veterans with liver disease nationally in the Veterans Health Administration

Purpose

While many studies have shown that liver diseases (LD) can be caused or exacerbated by substance use disorders (SUD), few have examined the proportion of adults with LD and SUD who receive mental health and addiction treatment or correlates of such use.

Design/methodology/approach

Using national Fiscal Year (FY) 2012 data from the United States Veterans Health Administration (VHA), the authors studied all 43,246 veterans diagnosed with both LD and SUD in FY 2012 and compared those who received mental health treatment (n = 30,456; 70.4%) to those who did not (n = 12,790; 29.6%).

Findings

Veterans who received mental health treatment were less like to be older than 75 years of age, more likely to have served during recent Middle East conflicts (Operation Iraqi Freedom or Operation Enduring Freedom), more likely to have been recently homeless and to have drug dependence as contrasted with alcohol dependence when compared with those who did not receive mental health treatment. Although the majority, 70.4%, received mental health treatment, only 30.6% of the total received specialized addiction treatment, and these veterans were more likely to experience homelessness and have drug dependence diagnoses.

Originality/value

This is the first study as per the authors’ best knowledge that broadly examines mental health and addiction treatment received by veterans with LD and SUD. High rates of mental health treatment in this population likely reflect the integrated nature of the VHA and its emphasis on providing comprehensive services to homeless veterans. Further research is needed to identify barriers to specialized addiction treatment in this population.

Incidence of Homelessness among Veterans Newly Diagnosed with Alzheimer's Disease and Related Dementias

BACKGROUND

To determine the incidence of homelessness among Veterans diagnosed with Alzheimer's disease and related dementias (ADRD).

METHODS

We used Veterans Affairs (VA) administrative records to identify Veterans with a new ADRD diagnosis anytime between 2010-2019. Among these Veterans, we calculated the incidence of homelessness, and estimated the association between demographics, comorbidities and hazard of homelessness.

RESULTS

The incidence rate of homelessness was highest for Veterans diagnosed with ADRD between 18-49 years of age (14.9 per 1,000 person-years; 95%CI: 13.6, 16.3) and lowest for Veterans diagnosed with ADRD at 90+ years (0.3 per 1,000 person-years; 95%CI: 0.2, 0.4). The adjusted hazard ratio of homelessness was higher for unmarried Veterans, and those with alcohol use disorder, substance use disorder, liver disease, depression, hypertension, lung disease, post-traumatic stress disorder and psychoses.

CONCLUSIONS

Younger age and being unmarried at the time of ADRD diagnosis are associated with a greater risk of experiencing homelessness.

Experiences of Military Veterans in a Therapeutic Horseback Riding Program

Posttraumatic stress disorder commonly occurs among U.S. military veterans. Therapeutic horseback riding (THR) has emerged as an adjunct therapy. We explored 20 veterans' perceived benefits, drawbacks and views of a 6-week THR program. Participants had confirmed diagnoses of posttraumatic stress disorder, traumatic brain injury, or both. Veterans rode the same horse weekly, the same day, at the same time. Data were collected as part of a randomized clinical trial testing the effects of THR on Post-Traumatic Stress Disorder. Veterans responded to an open-ended questionnaire. Content analysis was used for data analysis. Benefits were "Connection to the Horse," "Relaxing," "180 Degree Change," and "Meeting New People." Drawbacks were "None," "Struggle to Get There," "Pain," "Too Short," and "It is Structured." Overall perceptions were "I Absolutely Loved It," "Feel Again," "The Horse," "The People," and "No Worries." Participants viewed THR as positive. Findings may elucidate why THR may be clinically beneficial.

Homelessness and Veteran Status in Relation to Nonfatal and Fatal Opioid Overdose in Massachusetts

BACKGROUND

Compared with non-Veterans, Veterans are at higher risk of experiencing homelessness, which is associated with opioid overdose.

OBJECTIVE

To understand how homelessness and Veteran status are related to risks of nonfatal and fatal opioid overdose in Massachusetts.

DESIGN

A cross-sectional study.

PARTICIPANTS

All residents aged 18 years and older during 2011-2015 in the Massachusetts Department of Public Health's Data Warehouse (Veterans: n=144,263; non-Veterans: n=6,112,340). A total of 40,036 individuals had a record of homelessness, including 1307 Veterans and 38,729 non-Veterans.

MAIN MEASURES

The main independent variables were homelessness and Veteran status. Outcomes included nonfatal and fatal opioid overdose.

RESULTS

A higher proportion of Veterans with a record of homelessness were older than 45 years (77% vs. 48%), male (80% vs. 62%), or receiving high-dose opioid therapy (23% vs. 15%) compared with non-Veterans. The rates of nonfatal and fatal opioid overdose in Massachusetts were 85 and 16 per 100,000 residents, respectively. Among individuals with a record of homelessness, these rates increased 31-fold to 2609 and 19-fold to 300 per 100,000 residents. Homelessness and Veteran status were independently associated with higher odds of nonfatal and fatal opioid overdose. There was a significant interaction between homelessness and Veteran status in their effects on risk of fatal overdose.

CONCLUSIONS

Both homelessness and Veteran status were associated with a higher risk of fatal opioid overdoses. An understanding of health care utilization patterns can help identify treatment access points to improve patient safety among vulnerable individuals both in the Veteran population and among those experiencing homelessness.

An initiative to increase opioid overdose education and naloxone distribution for homeless veterans residing in contracted housing facilities

BACKGROUND

Up to 35% of veterans with opioid use disorder (OUD) are homeless, and veterans with OUD are nearly 29 times higher risk for homelessness; however, few are prescribed naloxone, an evidence-based intervention to reverse life-threatening opioid overdose.

LOCAL PROBLEM

Many housing facilities for homeless veterans contracted with the San Francisco Veterans Affairs Health Care System are located in neighborhoods with high rates of opioid overdose. No systematic interventions have been implemented to provide opioid overdose education and naloxone kits to veterans and staff at these facilities. This quality improvement (QI) initiative aimed to increase provision of opioid overdose education and naloxone for veterans and staff at contracted housing facilities.

METHODS

This was a prospective single-arm cohort QI intervention. All contracted veteran housing programs were included. Descriptive statistics evaluated results.

INTERVENTIONS

A total of 18 contracted veteran housing programs were contacted from July 2019 through January 2020 to schedule training.

RESULTS

Of those, 13 programs responded to outreach and 10 visits were completed at 8 housing facilities. Training was provided by pharmacist and nurse practitioner trainers to 26 staff members and 59 veterans. Naloxone was prescribed to 37 veterans.

CONCLUSIONS

A pharmacist-led and nurse practitioner-led initiative was effective in increasing veteran and staff access to opioid overdose education and naloxone at >44% contracted veteran housing facilities. Challenges included lack of response from housing programs, low veteran turn out, and inability to provide naloxone to veterans not enrolled/ineligible for health care. Future initiatives should examine strategies to standardize access in homeless veterans' programs.

Individualized Placement and Support Supported Employment for Justice-involved Homeless and Unemployed Veterans

BACKGROUND

Homelessness is a significant issue affecting the general US population. Two subsets of the population overrepresented in the US homeless population are justice involved individuals and Veterans. However, relatively little research has addressed alleviating homelessness in justice-involved Veterans (JIV). One direction for addressing homelessness in this population is facilitating employment.

OBJECTIVE

This study examined differences in housing and employment outcomes between homeless JIV enrolled in 2 different vocational rehabilitation conditions.

METHODS

This study evaluates vocational outcomes of Veterans experiencing homelessness enrolled in a larger US Department of Veterans Affairs-funded study. Participants were randomized into 2 groups: those who participated in a job search group, the About Face Vocational Program (AFVP) and those who received AFVP plus Individualized Placement and Support, Supported Employment (AFVP+IPS-SE).

RESULTS

Participants who received supported employment plus group were significantly more likely to secure employment compared with group alone. This significant difference was also found in individuals who identified as chronically homeless. Furthermore, participants who secured employment were significantly more likely to exit homelessness and secure housing, suggesting group membership had an indirect effect on housing status though improved employment outcomes.

CONCLUSIONS

Vocational rehabilitation groups combined with supported employment is appropriate and effective for homeless, JIV seeking employment and may also improve downstream housing outcomes.

A psychosocial mediational model of homelessness among U.S. male and female veterans who served in Iraq and Afghanistan

Few studies have focused on homelessness among Operations Iraqi Freedom, Enduring Freedom and New Dawn (OEF/OIF/OND) veterans, especially female veterans. An explanatory model of homelessness was constructed and tested for each gender. Data collected in the United States from 833 OEF/OIF/OND veterans (41.5% female; M_age  = 35.22, SD = 8.86) who completed the baseline assessment of the Survey of the Experiences of Returning Veterans between September 2011 and July 2014 were analysed. Path analysis was used to examine associations between risk factors and any lifetime homelessness, stratified by gender. Adverse childhood events (ACEs) and low social support were significantly associated with lifetime homelessness for both genders. Social support mediated associations between ACEs and homelessness, after controlling for sociodemographic factors. While sociodemographic risk factors are often considered in homeless prevention, these findings highlight the importance of social support among male and female OEF/OIF/OND veterans, underscoring the need to target this life domain in preventing homelessness.

A Systematic Review and Meta-Analysis of the Prevalence of Post-Traumatic Stress Disorder among Homeless People

Post-traumatic stress disorder (PTSD) is common among homeless people and is associated with an increased risk of mortality from suicide, medical causes, and drug-related problems. However, there are no previous systematic review and meta-analysis studies that reported the consolidated magnitude of PTSD among homeless people. A literature search was conducted on PubMed, Embase, and Scopus to discover pertinent studies that determined the prevalence of PTSD among the homeless. Articles were evaluated by titles, abstracts, and full-text. Comprehensive meta-analysis software was used to conduct the meta-analysis. Subgroup and sensitivity analysis were performed and Cochran's Q- and the I² test were used to assess heterogeneity. The evidence of publication bias was evaluated by using Egger's test and visual inspection of the symmetry in funnel plots. From the total, 19 studies with 20,364 participants across seven countries were included in the final analysis. Our meta-analysis revealed that the pooled prevalence of PTSD among homeless people was 27.38% (95% CI; 21.95-33.57). In our subgroup analysis, we found that the prevalence of PTSD was considerably high as measured by the screening instrument (35.93%) than the diagnostic instrument (23.57% %). The prevalence of PTSD among homeless showed a significant variation by the location of the studies, the instruments used to measure PTSD as well as the quality of the included studies. This review showed that the pooled prevalence estimate of PTSD among homeless peoples was remarkably high (27.38%). Early screening and treatment of PTSD among homeless peoples are warranted to alleviate suffering.
