BackgroundThe homeless population in the United States is aging. Aging-associated comorbidities are associated with increased symptoms.ObjectiveTo describe the prevalence of symptoms among older homeless-experienced adults, analyze factors associated with moderate-high physical symptom burden, and identify symptom clusters.DesignCross-sectional analysis within longitudinal cohort study.ParticipantsUsing population-based sampling from shelters, meal programs, encampments, and a recycling center in Oakland, CA, we recruited homeless adults aged ≥ 50 for a longitudinal cohort. This study includes participants who participated in the 18-month follow-up visit.Main measuresWe assessed physical symptoms using the Patient Health Questionnaire-15 (PHQ-15); psychological symptoms using the Center for Epidemiologic Studies Depression Scale (CES-D), Primary Care PTSD Screen (PC-PTSD), and psychiatric section of the Addiction Severity Index (ASI); loneliness using the Three-Item Loneliness Scale; and regret using a six-item regret scale.Key resultsTwo hundred eighty-three participants (75.6% men and 82.3% African-Americans) completed symptoms interviews. Over a third (34.0%) had moderate-high physical symptom burden. The most prevalent physical symptoms were joint pain, fatigue, back pain, and sleep trouble. Over half (57.6%) had psychological symptoms; 39.6% exhibited loneliness and 26.5% had high regret. In a multivariate model, being a woman (AOR 2.54, 95% CI 1.28-5.03), childhood abuse (AOR 1.88, 95% CI 1.00-3.50), cannabis use (AOR 2.59, 95% CI 1.38-4.89), multimorbidity (AOR 2.50, 95% CI 1.36-4.58), anxiety (AOR 4.30, 95% CI 2.24-8.26), hallucinations (AOR 3.77, 95% CI 1.36-10.43), and loneliness (AOR 2.32, 95% CI 1.26-4.28) were associated with moderate-high physical symptom burden. We identified four symptom clusters: minimal overall (n = 129), moderate overall (n = 68), high physical and high psychological (n = 67), and high physical and low psychological (n = 17).ConclusionsOlder homeless-experienced adults exhibit a high prevalence of symptoms across multiple dimensions. To reduce suffering, clinicians should recognize the interaction between symptoms and address multiple symptom dimensions.

BackgroundCigarette smoking rates among homeless adults are exceptionally high, contributing to health disparities experienced by this disadvantaged population. Concurrent nicotine and tobacco product use have been shown to result in greater health problems than cigarette smoking alone, and little is known about the rates, motives, and perceived impacts of concurrent use in this group. The purpose of this study is to explore concurrent use rates and constructs of interest among homeless adult daily smokers and to examine differences between concurrent users and non-concurrent users on cigarette dependence, perceived risk of smoking, readiness to quit, and the receipt of recent cessation intervention.MethodsParticipants (N = 396) were recruited from six homeless-serving agencies and/or shelters in Oklahoma City. Enrolled participants completed self-report questionnaires.ResultsThe rate of concurrent use was high -67.2%. Participants most frequently endorsed lower cost and a desire to cut down on cigarette smoking as motives for concurrent product use. Concurrent users indicated both a greater likelihood of developing a smoking-related disease if they did not quit for good and a greater number of past year quit attempts relative to non-concurrent users. There was no significant difference between concurrent users and non-concurrent users on readiness to quit or having received recent smoking cessation intervention.ConclusionThe need for cessation efforts that account for concurrent use for homeless adult smokers is great. Study findings indicate that concurrent users are commonly pursuing the reduction or elimination of cigarette usage and should be specifically targeted for cessation intervention.

This commentary examines the roles that communities and public policies play in the definition and processes of recovery for adults with mental illness. Policy, clinical, and consumer definitions of recovery are reviewed, which highlight the importance of communities and policies for recovery. This commentary then presents a framework for the relationships between community-level factors, policies, and downstream mental health outcomes, focusing on macroeconomic, housing, and health care policies; adverse exposures such as crime victimization; and neighborhood characteristics such as social capital. Initiatives that address community contexts to improve mental health outcomes are currently under way. Common characteristics of such initiatives and select examples are discussed. This commentary concludes with a discussion of providers', consumers', and other stakeholders' roles in shaping policy reform and community change to facilitate recovery.

PurposeTo examine attitudes toward tobacco control policies among older African American homeless-experienced smokers.ApproachA qualitative study.SettingOakland, California.ParticipantsTwenty-two African American older homeless-experienced smokers who were part of a longitudinal study on health and health-related outcomes (Health Outcomes of People Experiencing Homelessness in Older Middle Age Study).MethodWe conducted in-depth, semistructured interviews with each participant to explore beliefs and attitudes toward tobacco use and cessation, barriers to smoking cessation, and attitudes toward current tobacco control strategies including raising cigarette prices, smoke-free policies, and graphic warning labels. We used a grounded theory approach to analyze the transcripts.ResultsCommunity social norms supportive of cigarette smoking and co-use of tobacco with other illicit substances were strong motivators of initiation and maintenance of tobacco use. Self-reported barriers to cessation included nicotine dependence, the experience of being homeless, fatalistic attitudes toward smoking cessation, substance use, and exposure to tobacco industry marketing. While participants were cognizant of current tobacco control policies and interventions for cessation, they felt that they were not specific enough for African Americans experiencing homelessness. Participants expressed strong support for strategies that de-normalized tobacco use and advertised the harmful effects of tobacco.ConclusionOlder African American homeless-experienced smokers face significant barriers to smoking cessation. Interventions that advertise the harmful effects of tobacco may be effective in stimulating smoking cessation among this population.

ObjectiveCommunity Partners in Care (CPIC) was a group-randomized study of two approaches to implementing expanded collaborative depression care: Community Engagement and Planning (CEP), a coalition approach, and Resources for Services (RS), a technical assistance approach. Collaborative care networks in both arms involved health care and other agencies in five service sectors. This study examined six- and 12-month outcomes for CPIC participants with serious mental illness.MethodsThis secondary analysis focused on low-income CPIC participants from racial-ethnic minority groups with serious mental illness in underresourced Los Angeles communities (N=504). Serious mental illness was defined as self-reported severe depression (≥20 on the Patient Health Questionnaire-8) at baseline or a lifetime history of bipolar disorder or psychosis. Logistic and Poisson regression with multiple imputation and response weights, controlling for covariates, was used to model intervention effects.ResultsAmong CPIC participants, 50% had serious mental illness. Among those with serious mental illness, CEP relative to RS reduced the likelihood of poor mental health-related quality of life (OR=.62, 95% CI=.41-.95) but not depression (primary outcomes); reduced the likelihood of having homelessness risk factors and behavioral health hospitalizations; increased the likelihood of mental wellness; reduced specialty mental health medication and counseling visits; and increased faith-based depression visits (each p

BackgroundSeveral studies suggest that U.S. state-level legalization of cannabis for medical purposes may be associated with reductions in opioid use; yet its relationship with stimulant use, particularly in high-risk populations like unstably housed women, has received less attention. The purpose of this study was to estimate independent associations between medical and non-medical use of cannabis and use of stimulants and opioids among unstably housed women.MethodsCross-sectional data were analyzed from 245 women in the SHADOW study, a community based cohort in San Francisco, CA, in which HIV+ women were oversampled (126 HIV+ and 119 HIV-).ResultsCompared to no cannabis use in the past 6 months (51%), non-medical cannabis use (28%) was associated with a higher adjusted odds of using stimulants (Adjusted Odds Ratio [AOR]=4.34, 95% confidence interval [CI]: 2.17-8.70) and opioids (AOR=3.81, 95% CI: 1.78-8.15). Compared to no cannabis use, medical cannabis use (21%) was not significantly associated with stimulant or opioid use. Compared to non-medical cannabis use, however, medical cannabis use was associated with lower adjusted odds of using stimulants (AOR=0.42, 95% CI: 0.18-0.96). These associations were not modified by HIV status.ConclusionsAssociations between use of cannabis and "street drugs" depend on whether the cannabis is obtained through a medical context. Interventions, research, and policy considering the influence of cannabis on the use of other drugs may benefit by distinguishing between medical and non-medical cannabis use.

BACKGROUND: Homeless women are at high risk for substance use disorder (SUD), and are a growing proportion of the homeless population. However, homeless women experience barriers to engaging in substance use services. OBJECTIVES: Among homeless women with SUD, to explore service use, motivation to change, service barriers, and willingness to have substance use and mental health problems addressed in primary health care. METHODS: Women with SUD were sampled from 11 Health Care for the Homeless (HCH) primary care clinics in 9 states, yielding 241 with either an alcohol or drug use disorder who then completed questions about SUD services. RESULTS: Over 60% of women with dual alcohol and drug use disorders used some type of SUD service in the past year, while 52% with a drug only disorder, and 44% with an alcohol only disorder used services. The most mentioned barrier to service use was depression, but cost, wait time, where to find treatment, and facilities located too far away, were also frequently noted. A large proportion across all groups indicated high motivation for treatment and willingness to discuss their SUD in a primary care setting. CONCLUSION: There are continued barriers to SUD service use for homeless women despite high motivation for treatment, and willingness to be asked about SUD and mental health problems in primary care. HCH primary care sites should more systematically ask about SUD and mental health issues and address womens expressed need for support groups and alternative therapies to more holistically address their SUD needs.

IntroductionAlthough traditional patient-centered medical homes (PCMHs) are effective for patients with complex needs, it is unclear whether homeless-tailored PCMHs work better for homeless veterans. We examined the impact of enrollment in a Veterans Health Administration (VHA) homeless-tailored PCMH on health services use, cost, and satisfaction compared with enrollment in a traditional, nontailored PCMH.MethodsWe conducted a prospective, multicenter, quasi-experimental, single-blinded study at 2 VHA medical centers to assess health services use, cost, and satisfaction during 12 months among 2 groups of homeless veterans: 1) veterans receiving VHA homeless-tailored primary care (Homeless-Patient Aligned Care Team [H-PACT]) and 2) veterans receiving traditional primary care services (PACT). A cohort of 266 homeless veterans enrolled from June 2012 through January 2014.ResultsCompared with PACT patients, H-PACT patients had more social work visits (4.6 vs 2.7 visits) and fewer emergency department (ED) visits for ambulatory care-sensitive conditions (0 vs 0.2 visits); a significantly smaller percentage of veterans in H-PACT were hospitalized (23.1% vs 35.4%) or had mental health-related ED visits (34.1% vs 47.6%). We found significant differences in primary care provider-specific visits (H-PACT, 5.1 vs PACT, 3.6 visits), mental health care visits (H-PACT, 8.8 vs PACT, 13.4 visits), 30-day prescription drug fills (H-PACT, 40.5 vs PACT, 58.8 fills), and use of group therapy (H-PACT, 40.1% vs PACT, 53.7%). Annual costs per patient were significantly higher in the PACT group than the H-PACT group ($37,415 vs $28,036). In logistic regression model of acute care use, assignment to the H-PACT model was protective as was rating health "good" or better.ConclusionHomeless veterans enrolled in the population-tailored primary care approach used less acute care and costs were lower. Tailored-care models have implications for care coordination in the US Department of Veterans Affairs VA and community health systems.

ObjectivesA randomized controlled study was conducted with 422 homeless, stimulant-using gay/bisexual (G/B) men and 29 transgender women (n = 451) to assess two community-based interventions to reduce substance abuse and improve health: (a) a nurse case-managed program combined with contingency management (NCM + CM) versus (b) standard education plus contingency management (SE + CM).Study designHypotheses tested included: a) completion of hepatitis A/B vaccination series; b) reduction in stimulant use; and c) reduction in number of sexual partners.MethodsA deconstructive cost analysis approach was utilized to capture direct costs associated with the delivery of both interventions. Based on an analysis of activity logs and staff interviews, specific activities and the time required to complete each were analyzed as follows: a) NCM + CM only; b) SE + CM only; c) time to administer/record vaccines; and d) time to receive and record CM visits. Cost comparison of the interventions included only staffing costs and direct cash expenditures.ResultsThe study outcomes showed significant over time reductions in all measures of drug use and multiple sex partners, compared to baseline, although no significant between-group differences were detected. Cost analysis favored the simpler SE + CM intervention over the more labor-intensive NCM + CM approach. Because of the high levels of staffing required for the NCM relative to SE, costs associated with it were significantly higher.ConclusionsFindings suggest that while both intervention strategies were equally effective in achieving desired health outcomes, the brief SE + CM appeared less expensive to deliver.

Background: People experiencing homelessness often face obstacles accessing health and social care support. Challenges are further exacerbated when support provision for multiple unmet needs are not integrated or coordinated. To overcome these challenges, there has been growing attention on integrating and co-locating health and wellbeing services for people experiencing homelessness. In an urban area of North East England, a long-standing Hub or 'drop-in centre' offers a range of health and wellbeing support by bringing together the different health and care system agencies in one space. However, little is known about the perspectives of providers on what works well and less well in how the different services are coordinated., Methods: Using a participatory action research approach, a qualitative service evaluation was undertaken between June and September 2023. Fourteen interviews were conducted with providers who work in a paid or voluntary capacity operating some of their service offerings or support in the Hub. Interview transcripts were analysed using inductive reflexive thematic analysis., Results: Three themes were evident from the evaluation: 1) location and space matter, 2) co-location and relationships make a difference, and 3) service consistency and flexibility are paramount., Conclusion: Co-locating support to cover the breadth of health and care needs has the potential to increase engagement and access for people experiencing homelessness, and to enhance trust with service users and between agencies. This model provides a unique example of co-location and integration of support, particularly with it being operated by a community housing organisation., Competing Interests: Declarations Ethics approval and consent to participate All data collection was performed in accordance with the Declaration of Helsinki.

Background: Veterans are disproportionately more likely to experience homelessness and unstable housing (HUH) compared with the general population. Cardiovascular disease is the leading cause of death among Veterans experiencing HUH. We aimed to understand whether HUH status among Veterans with preexisting cardiovascular disease was associated with disparities in cardiovascular care access and utilization., Methods: Retrospective study of all Veterans with preexisting cardiovascular disease between 2017 and 2019 using Veterans Affairs Corporate Data Warehouse and Homeless registry data. Primary outcomes were annual outpatient visits for cardiovascular disease management and visits with cardiovascular disease-related specialists. Secondary outcomes included cardiovascular disease-related procedures and emergency department visits and hospitalizations. HUH status was determined based on response to a screener, diagnostic codes, or use of homelessness services, and outcomes were assessed in the first year HUH status was determined. After applying inverse probability of treatment weighting, negative binomial and logistic regression models were fit to estimate the association between experiencing HUH and the outcomes of interest., Results: Among 1 357 973 Veterans (mean age, 71.6 [SD=10.6] years; 2.5% female) with preexisting cardiovascular disease, 56 093 were identified as experiencing HUH during the study period. Veterans experiencing HUH had fewer outpatient visits for cardiovascular disease management or with cardiovascular disease-related specialists (4.3% [95% CI, 2.5%-6.1%] and 14.1% [95% CI, 12.5%-15.8%], respectively) compared with housed Veterans. HUH status was associated with lower rates of receiving certain procedures including coronary artery bypass graft, lower extremity revascularization, and carotid artery stenosis interventions and higher rates of all-cause and cardiovascular emergency department visits and hospitalizations., Conclusions: Veterans with chronic cardiovascular conditions experiencing HUH had lower rates of outpatient visits for cardiovascular disease management and higher rates of emergency department visits and hospitalizations. Given the disproportionate burden of cardiovascular disease in this population, interventions to improve access to cardiovascular care are needed., Competing Interests: Dr Khatana receives funding from the National Heart, Lung, and Blood Institute (K23HL153772 and R01HL171157) and the American Heart Association (20CDA35320251) and has received personal fees from AcademyHealth.

Congregate homeless shelters are disproportionately affected by infectious disease outbreaks. We describe enterovirus epidemiology across 23 adult and family shelters in King County, Washington, USA, during October 2019-May 2021, by using repeated cross-sectional respiratory illness and environmental surveillance and viral genome sequencing. Among 3,281 participants >3 months of age, we identified coxsackievirus A21 (CVA21) in 39 adult residents (3.0% [95% CI 1.9%-4.8%] detection) across 7 shelters during October 2019-February 2020. We identified enterovirus D68 (EV-D68) in 5 adult residents in 2 shelters during October-November 2019. Of 812 environmental samples, 1 was EV-D68-positive and 5 were CVA21-positive. Other enteroviruses detected among residents, but not in environmental samples, included coxsackievirus A6/A4 in 3 children. No enteroviruses were detected during April 2020-May 2021. Phylogenetically clustered CVA21 and EV-D68 cases occurred in some shelters. Some shelters also hosted multiple CVA21 lineages.

Background: Studies have posited that substance use is associated with, or contributes to, homelessness for 2S/LGBTQ+ youth. However, interconnections between these issues are poorly articulated., Methods: This community-based photovoice study describes the narratives used by 2S/LGBTQ+ youth about how substance use featured in their pathways to homelessness. Employing constructionist narrative analysis, two storylines were inductively derived from participant-produced photographs and photovoice interviews with 32 2S/LGBTQ+ youth in Vancouver, Canada., Results: Taking refuge narratives centered on 2S/LGBTQ+ youths' use of substances to cope with intersecting hardships and minority stressors they had faced growing up, and when transitioning to homelessness. From playing into precarity narratives focused on the shifting possibilities and tensions of what sexualized crystal methamphetamine use can surface for 2S/LGBTQ+ youth in terms of facilitating connection and release and simultaneously invoking discomforts, including eviction from their family home., Conclusions: These narratives can usefully be anticipated and recognized to better understand and address the social contexts in which 2S/LGBTQ+ youth experience substance use and associated harms, especially homelessness. They affirm the need for tailored supports for 2S/LGBTQ+ youth who use drugs in the lead-up to and after becoming homeless, including the provision of care that better recognizes youths' pursuits of becoming and belonging in the context of marginalization, and that takes a harm reduction approach to addressing the role of substance use in these pursuits., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Background and Objectives: Comprehensive definitions of social issues and populations can set the stage for the development of responsive policies and practices. Yet despite the rise of late-life homelessness, the phenomenon remains narrowly understood and ill-defined., Research Design and Methods: This article and the definition that ensued are based on the reconceptualization of interview data derived from a critical ethnography conducted in Montreal, Canada, with older homeless persons (N = 40) and service providers (N = 20)., Results: Our analysis suggests that definitions of late-life homelessness must include 4 intersecting components: (1) age, eligibility, and access to services; (2) disadvantage over the life course and across time; (3) social and spatial processes of exclusion that necessitate aging in "undesirable" places; and (4) unmet needs that result from policy inaction and nonresponse., Discussion and Implications: The new definition derived from these structural and relational components captures how the service gaps and complex needs identified in earlier works are shaped by delivery systems and practices whose effect is compounded over time. It provides an empirically grounded and conceptually solid foundation for the development of better responses to address homelessness in late life., (© The Author(s) 2024.

Background and Objectives: Coordination of governmental action is crowded with policies and programs that are highly interdependent, sometimes operating in silos if not contradicting each other. These dilemmas, or administrative quagmires, are heightened for older adults in general, but they are particularly problematic for marginalized older adults because these groups often require public assistance and support. This scoping review studies the coordination of governmental action on aging published in social science journals, focusing on 6 groups of marginalized older adults: those with histories of immigration, individuals with severe mental health problems, those who have had experiences of homelessness, formerly incarcerated individuals, members of the LGBT (lesbian, gay, bisexual, and transgender) community, and individuals living in a rural area., Research Design and Methods: A 5-stage scoping review methodology was followed, and 53 articles (published between 2000 and 2022) from 5 social science databases were analyzed., Results: The analysis revealed a limited number of contributions with coordination as a primary focus. Understandings of coordination varied but tended to examine structure, organization, and relationships between sectors. When coordination was the primary object of a study, it was often analyzed in 1 specific policy area or within a clinical setting along the lines of facilitating care coordination., Discussion and Implications: This scoping review reveals a mutual neglect on the part of public administration and policy scholars toward marginalized older adults and a lack of public administration considerations on the part of scholars studying long-term care and social service programs for these marginalized older adults., (© The Author(s) 2024.

In 2023, approximately 650,000 people experienced homelessness (PEH) nightly in the United States, the highest number recorded in the country's history. This alarming statistic has made homelessness a key issue in the 2024 elections, especially with the White House's goal to reduce homelessness by 25% by 2025. Despite efforts and investments, homelessness remains a persistent public health challenge. The recent inclusion of street medicine services in Center for Medicare and Medicaid Services (CMS) billing codes represents a significant step forward. Street medicine, defined by CMS as healthcare provided in non-permanent locations to unsheltered individuals, now qualifies for Medicare reimbursement. This policy change, alongside state-level initiatives, aims to improve healthcare access for the unhoused, particularly older adults. However, challenges remain in establishing adequate fee schedules and integrating care management. Despite these obstacles, the integration of healthcare and housing services is crucial for addressing homelessness effectively, promoting stability, and improving health outcomes for PEH. This manuscript explores the history, practical guidance, and potential impacts of these developments on homelessness and public health., (© 2024.

Background: Consistent use of sexually transmitted infection (STI) prevention methods is proven to decrease transmission of STIs. However, rates continue to rise within the United States, particularly among high-risk populations. Women experiencing homelessness may face barriers to access reproductive health care. This quality improvement initiative sought to examine perceived barriers to STI prevention and opportunities for expanding STI prevention services and education for women experiencing homelessness., Methods: Surveys were administered during a 1-day health event in August 2023 at a clinic that predominately serves persons experiencing homelessness in North Texas. Respondents included adult, nonpregnant, English-speaking individuals assigned female at birth with a history of homelessness. Demographic characteristics, sexual history, participants' knowledge of STIs, and perceived barriers to obtaining sexual health care were gathered. Participants had the opportunity to suggest methods for improving access to STI care., Results: Among participants (n = 36), more than half (59%) were tested for STIs within the past year. Most preferred condoms for STI prevention. The average knowledge score among questions about STI transmission and methods of prevention was 65%, with the lowest scores observed among trichomoniasis (39% correct), preexposure prophylaxis (31%), and dental dams (25%). Common barriers included cost (33%) and side effects (33%). One-third (36%) of participants reported no barriers to the use of prevention products., Conclusions: Findings highlight the need for educational opportunities among this population to increase knowledge of STI transmission and prevention. Patients may benefit from clinicians emphasizing education and increasing the visibility of services., Competing Interests: Conflict of Interest and Sources of Funding: The authors have no conflict of interest to disclose.

Homelessness, particularly unsheltered homelessness is a public health emergency in the U.S. Street outreach programs have demonstrated efficacy in connecting people to housing, initiating or retaining people in primary care, improving access to mental health services, and increasing treatment for substance use disorder. Effective outreach is generally characterized by trained, multidisciplinary teams that visit clients where they are, forming trusting relationships over time. Public health nurses working on outreach teams have opportunities to exercise their full scope and standards of practice and advance street outreach to the benefit of a distinctly marginalized group., (© 2024 Wiley Periodicals LLC.)

Background: The opioid overdose epidemic disproportionately impacts people experiencing homelessness. Outpatient-based opioid treatment (OBOT) programs have been established in homeless health care settings across the USA, but little is known about the success of these programs in engaging and retaining this highly marginalized patient population in addiction care., Objective: To evaluate predictors of initial engagement and subsequent attendance in a homeless-tailored OBOT program., Design: Prospective cohort study with 4 months of follow-up., Participants: A total of 148 homeless-experienced adults (≥18 years) who newly enrolled in the Boston Healthcare for the Homeless Program (BHCHP) OBOT program over a 1-year period (1/6/2022-1/5/2023)., Main Measures: The primary outcomes were (1) initial OBOT program engagement, defined as having ≥2 additional OBOT visits within 1 month of OBOT enrollment, and (2) subsequent OBOT program attendance, measured monthly from months 2 to 4 of follow-up., Key Results: The average age was 41.7 years (SD 10.2); 23.6% were female, 35.8% were Hispanic, 12.8% were non-Hispanic Black, and 43.9% were non-Hispanic White. Over one-half (57.4%) were initially engaged. OBOT program attendances during months 2, 3, and 4 were 60.8%, 50.0%, and 41.2%, respectively. One-quarter (24.3%) were initially engaged and then attended the OBOT program every month during the follow-up period. Participants in housing or residential treatment programs (vs. unhoused; adjusted odds ratios (aORs) = 2.52; 95% CI = 1.17-5.44) and those who were already on or initiated a medication for opioid use disorder (OUD) (aOR = 6.53; 95% CI = 1.62-26.25) at the time of OBOT enrollment had higher odds of engagement. Older age (aOR = 1.74 per 10-year increment; 95% CI = 1.28-2.38) and initial engagement (aOR = 3.50; 95% CI = 1.86-6.59) conferred higher odds of attendance., Conclusions: In this study, over half initially engaged with the OBOT program, with initial engagement emerging as a strong predictor of subsequent OBOT program attendance. Interventions aimed at enhancing initial OBOT program engagement, including those focused on housing and buprenorphine initiation, may improve longer-term outcomes in this marginalized population., Competing Interests: Declarations: Conflict of Interest: Dr. Baggett receives author royalties from UpToDate.

Background: The COVID-19 pandemic and subsequent implementation of public health policies exacerbated multiple intersecting systemic inequities, including homelessness. Housing is a key social determinant of health that played a significant part in the front-line defence against COVID-19, posing challenges for service providers working with people experiencing homelessness (PEH). Public health practitioners and not-for-profit organizations (NFPs) had to adapt existing COVID-19 policies and implement novel measures to prevent the spread of disease within congregate settings, including shelters. It is essential to share the perspectives of service providers working with PEH and their experiences implementing policies to prepare for future public health emergencies and prevent service disruptions., Methods: In this qualitative case study, we explored how service providers in the non-profit sector interpreted, conceptualized, and implemented COVID-19 public health outbreak control policies in Nova Scotia. We interviewed 11 service providers between September and December 2020. Using thematic analysis, we identified patterns and generated themes. Local, provincial, and national policy documents were useful to situate our findings within the first year of the COVID-19 pandemic and contextualize participants' experiences., Results: Implementing policies in the context of homelessness was difficult for service providers, leading to creative temporary solutions, including pop-up shelters, a dedicated housing isolation phone line, comfort stations, and harm reduction initiatives, among others. There were distinct rural challenges to navigating the pandemic, which stemmed from technology limitations, lack of public transportation, and service closures. This case study illustrates the importance of flexible and context-specific policies required to support PEH and mitigate the personal and professional impact on service providers amid a public health emergency. Innovative services and public health collaboration also exemplified the ability to enhance housing services beyond the pandemic., Conclusions: The results of this project may inform context-specific emergency preparedness and response plans for COVID-19, future public health emergencies, and ongoing housing crises., (© 2024.

There are increased sector-wide efforts within health and social care systems to engage those with lived experience in service design, delivery, and monitoring - aiming to secure more equitable health outcomes. However, critical knowledge gaps persist around how national whole-system engagement strategies can account for the challenges experienced by populations that encounter exclusion within complex multi-layered systems. This includes a failure to delineate shared challenges across groups, and to develop transferable cross-group frameworks to assist sector-wide change. There is, therefore, a danger that those groups already least heard will be collectively left behind. With a view to informing a more inclusive engagement strategy in Ireland, this national study aims to investigate multi-level (policy and strategic, operational, on-the-ground services, individual) shared challenges impacting engagement for five populations who have been identified as underserved groups in a complex health and social care system, including: (1) those who misuse drugs and alcohol, (2) those who are experiencing homelessness, (3) those experiencing mental health, (4) migrants and those of minority ethnicies, and (5) Irish Travellers. Adopting a mixed-methods approach which draws on an evidence-informed multistakeholder perspective, this study employs data from: focus groups and life-course interviews with lived-experience populations (n=136), five focus groups (n=39) and a national on-line survey (n=320) with population-specific services providers; and national-level stakeholder interviews (n=9). Two cross-group participatory consultative forums with lived-experience and provider participants (n=28) were used to co-produce priority action areas based on study findings. This article presents findings on shared challenges in engaging these groups around leadership and commitment, implementation and action, population capacities, trust, and representation, stigma, and discrimination. Derived from these challenges, six development areas are presented to advance an inclusive equitable engagement approach in Ireland. These comprise: 1) balancing top-down prioritisation, and bottom-up direction; 2) sustaining multi-level, multi-form implementation; 3) measuring effectiveness and action; 4) embedding inclusive equitable engagement; 5) trust as a prerequisite, and outcome; and 6) an equalising, agency empowering agenda., (© 2024.

Introduction: Despite increased awareness of the detrimental relationship between homelessness and health, people experiencing homelessness remain an underserved population in health and social care research. Due to barriers affecting the accessibility of medicine and healthcare services, as well as reported competing priorities such as food and shelter, evidence has demonstrated that people experiencing homelessness are less likely to undergo routine examinations, receive diagnoses and adhere to prescribed medical treatments. To enhance service design and access for those experiencing homelessness, it is critical to better recognise, understand and address the barriers these individuals face. This meta-ethnography aims to identify barriers, enablers and interventions to begin addressing this inequality gap., Methods: A systematic literature search was undertaken in October and re-ran in December 2023 across four databases: MEDLINE, Embase, CINAHL and Scopus. Qualitative studies were included if they addressed barriers, enablers and interventions aimed at tackling medicines and health service inequalities among populations experiencing homelessness. Study quality was assessed using the Joanna Briggs Institute critical appraisal checklist. Data were synthesised using a meta-ethnographic approach, as outlined by Noblit and Hare. The review was registered on PROSPERO (CRD42024511502) and performed according to PRISMA guidelines., Results: This meta-ethnographic systematic review synthesised data from eight studies across multiple countries. Three overarching third-order constructs (termed 'themes') were developed through reciprocal translation and centred around: recognising and acknowledging the discrimination, stigma and barriers experienced when using current services; exploring safe and practical use of medicines and the promotion of general health education and appreciating strategies to tackle inequalities, namely community outreach programmes designed for homeless communities., Conclusion: This work highlighted the barriers, enablers and interventions that sought to address the inequalities affecting people experiencing homelessness in accessing medication and healthcare services. Future research should utilise lived-experience narratives and co-design to further explore ways to tackle wider healthcare accessibility inequalities for this minoritised population., Trial Registration: Not applicable, as this is a systematic review., Patient or Public Contribution: Public contributors (minority research champions and one public health research champion, H.K.G. and T.G.) informed and shaped this project during study design and conceptualisation. They helped to ensure that the study was conducted, and the findings were reported with sensitivity., (© 2024 The Author(s). Health Expectations published by John Wiley & Sons Ltd.)

Introduction: There is a paucity of research on and a limited understanding of patient and public involvement (PPI) in the context of research in homelessness and, in particular, direct involvement of people with lived and living experience of homelessness (PEH) as expert advisors. We aim to report on outcomes and reflections from lived experience advisory panel (LEAP) meetings and PPI activities, held throughout the study lifecycle of a pilot randomised-controlled trial (RCT) focused on evaluating integrated health and practical support for PEH., Methods: Community Pharmacy Homeless Outreach Engagement Non-medical Independent prescribing Rx (PHOENIx Community Pharmacy RCT) is an integrated health and social care intervention for people experiencing homelessness who present to community pharmacy. Intervention includes weekly support from a pharmacist prescriber and a third sector support worker for up to 6 months. PPI activities undertaken throughout the study were documented, including outcomes of LEAP meetings. Outcome reporting followed Guidance for Reporting Involvement of Patients and the Public 2 Short Form (GRIPP2-SF)., Results: In total, 17 members were recruited into the LEAP; six meetings (three in two study sites) were held. PPI input was also received through representation from homelessness third sector organisation staff as study co-applicants and core membership in the trial steering committee. Together, the PPI activities helped shape the study proposal, design of study materials, data analysis and dissemination materials. LEAP panel members offered valuable input via their experience and expertise into the delivery and refinement of interventions. Although longitudinal input was received from some LEAP members, ensuring repeat attendance in the pre-planned meetings was challenging., Conclusion: People who face social exclusion and marginalisation can provide highly valuable input as equal partners in co-design and delivery of interventions seeking to improve their health and well-being. Fluid membership and flexible methods of seeking and incorporating advice can offer pragmatic approaches to minimising barriers to continued involvement in research., Patient or Public Contribution: This study reports findings and learning relevant to involvement of people with lived and living experience of homelessness as advisors in a research study. It is important for researchers to offer fluid memberships and use diverse methods to receive input from lived experience members, as traditional PPI methodology may be insufficient to ensure inclusivity. Staff and volunteers from third sector organisations were important PPI partners who bring their experience based on frontline service provision, often as the first port of call for people experiencing severe and multiple disadvantage., Trial Registration: ISRCTN88146807., (© 2024 The Author(s).

Background: Homeless-experienced veterans (HEVs) are an important but challenging group to care for in the U.S. Department of Veterans Affairs health care system, and there are opportunities to examine the potential of integrative and complementary medicine approaches. Methods: This observational study enrolled 33 HEVs in a one-group observational, prospective study of Battlefield Acupuncture (BFA) with a monthly follow-up for 3 months after initiating BFA. Results: Linear growth curve analyses revealed a significant improvement in overall pain scores and scores on the effects of pain on activity level, mood, and stress. Conclusions: These preliminary findings suggest the potential of BFA to improve pain among HEVs as an area for further research.

It's now well appreciated that social determinants of health are the strongest predictors of our health and well-being. A good argument could be made that housing is at the top of the pyramid of these determinants. And, surprisingly, housing is also the social determinant that could rapidly turn on a dime-that is, with sufficient political will, creating access to housing could be radically expanded in short order. (Unfortunately, of course, it's true one can also become suddenly homeless, since few protections exist in policy or capitalist economies to prevent it). That alone sets it apart from social factors such as education and racism-conditions that take a long time to change. In contrast to long-term interventions (education) or culturally stubborn and historically rooted problems (racism), housing is rapidly malleable. In this article, we describe the social condition of homelessness in two settings, comparing and contrasting the concepts, causes, and consequences, along with how people are mobilizing to challenge the conditions that create their housing insecurity. As we review the factors that create housing conditions in each setting, we propose some universal international principles for a new approach to the human right of decent and secure housing., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

WHAT IS KNOWN ON THE SUBJECT?: This paper acknowledges the profound and lasting impact of childhood abuse on substance use and homelessness. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: It underscores the inherent value and humanity of every individual, regardless of their struggles. That a comprehensive approach to mental health care, encompassing medication, therapy and a secure environment, is imperative. WHAT ARE THE IMPLICATIONS FOR MENTAL HEALTH NURSING?: Early intervention and recognising individuals who suffer in silence are paramount. Mental health nurses must have the courage to ask uncomfortable questions and truly hear the unspoken words. Mental health nurses should never underestimate the power of simply being present with someone during their darkest moments. This simple act can wield significant influence., (© 2024 The Authors.

Background: Opioid use disorder (OUD) is a growing public health crisis, with opioids involved in an overwhelming majority of drug overdose deaths in the United States in recent years. While medications for opioid use disorder (MOUD) effectively reduce overdose mortality, only a minority of patients are able to access MOUD; additionally, those with unstable housing receive MOUD at even lower rates., Objective: Because MOUD access is a multifactorial issue, we leverage machine learning techniques to assess and rank the variables most important in predicting whether any individual receives MOUD. We also seek to explain why persons experiencing homelessness have lower MOUD access and identify potential targets for action., Methods: We utilize a gradient boosted decision tree algorithm (specifically, XGBoost) to train our model on SAMHSA's Treatment Episode Data Set-Admissions, using anonymized demographic and clinical information for over half a million opioid admissions to treatment facilities across the United States. We use Shapley values to quantify and interpret the predictive power and influencing direction of individual features (i.e., variables)., Results: Our model is effective in predicting access to MOUD with an accuracy of 85.97% and area under the ROC curve of 0.9411. Notably, roughly half of the model's predictive power emerges from facility type (23.34%) and geographic location (18.71%); other influential factors include referral source (6.74%), history of prior treatment (4.41%), and frequency of opioid use (3.44%). We also find that unhoused patients go to facilities that overall have lower MOUD treatment rates; furthermore, relative to housed (i.e., independent living) patients at these facilities, unhoused patients receive MOUD at even lower rates. However, we hypothesize that if unhoused patients instead went to the facilities that housed patients enter at an equal percent (but still received MOUD at the lower unhoused rates), 89.50% of the disparity in MOUD access would be eliminated., Conclusion: This study demonstrates the utility of a model that predicts MOUD access and both ranks the influencing variables and compares their individual positive or negative contribution to access. Furthermore, we examine the lack of MOUD treatment among persons with unstable housing and consider approaches for improving access., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Esguerra, Weinandy.

The assessment of social determinants of health (SDoH) within healthcare systems is crucial for comprehensive patient care and addressing health disparities. Current challenges arise from the limited inclusion of structured SDoH information within electronic health record (EHR) systems, often due to the lack of standardized diagnosis codes. This study delves into the transformative potential of large language models (LLM) to overcome these challenges. LLM-based classifiers-using Bidirectional Encoder Representations from Transformers (BERT) and A Robustly Optimized BERT Pretraining Approach (RoBERTa)-were developed for SDoH concepts, including homelessness, food insecurity, and domestic violence, using synthetic training datasets generated by generative pre-trained transformers combined with authentic clinical notes. Models were then validated on separate datasets: Medical Information Mart for Intensive Care-III and our institutional EHR data. When training the model with a combination of synthetic and authentic notes, validation on our institutional dataset yielded an area under the receiver operating characteristics curve of 0.78 for detecting homelessness, 0.72 for detecting food insecurity, and 0.83 for detecting domestic violence. This study underscores the potential of LLMs in extracting SDoH information from clinical text. Automated detection of SDoH may be instrumental for healthcare providers in identifying at-risk patients, guiding targeted interventions, and contributing to population health initiatives aimed at mitigating disparities., Competing Interests: Competing interests statement:The authors declare no competing interest.

Background: People experiencing homelessness have increased prevalence, morbidity, and mortality of cardiovascular disease (CVD), attributable to several traditional and non-traditional risk factors. While this burden is well-known, mainstream CVD management plans and healthcare delivery have not been developed with people experiencing homelessness in mind nor tailored to their unique context. The overall objective of this work was to explore and synthesize what is known about CVD management experiences, programs, interventions, and/or recommendations specifically for people experiencing homelessness., Methods: We conducted a scoping review to combine qualitative and quantitative studies in a single review using the Arksey and O'Malley framework and lived experience participation. We performed a comprehensive search of OVID Medline, Embase, PsychINFO, CINAHL, Web of Science, Social Sciences Index, Cochrane, and the grey literature with key search terms for homelessness, cardiovascular disease, and programs. All dates, geographic locations, and study designs were included. Articles were analyzed using conventional content analysis., Results: We included 37 articles in this review. Most of the work was done in the USA. We synthesized articles' findings into 1) barriers/challenges faced by people experiencing homelessness and their providers with CVD management and care delivery (competing priorities, lifestyle challenges, medication adherence, access to care, and discrimination), 2) seven international programs/interventions that have been developed for people experiencing homelessness and CVD management with learnings, and 3) practical recommendations and possible solutions at the patient encounter level (relationships, appointment priorities, lifestyle, medication), clinic organization level (scheduling, location, equipment, and multi-disciplinary partnership), and systems level (root cause of homelessness, and cultural safety)., Conclusions: There is no 'one-size-fits all' approach to CVD management for people experiencing homelessness, and it is met with complexity, diversity, and intersectionality based on various contexts. It is clear, however, we need to move to more practically-implemented, community-driven solutions with lived experience and community partnership at the core. Future work includes tackling the root cause of homelessness with affordable housing, exploring ways to bring cardiac specialist care to the community, and investigating the role of digital technology as an avenue for CVD management in the homeless community. We hope this review is valuable in providing knowledge gaps and future direction for health care providers, health services research teams, and community organizations., (© 2024. The Author(s).)

Background - The new increasing homeless lately consist of women, children, youth, the elderly and marginalized ethnic or migrant groups. Some of them are working and earn salaries, however, the income is not sufficient to live modestly. Purpose - The purpose of this research is to establish a desired support system to eradicate urban homelessness in the country. Design/methodology/approach - This is an exploratory descriptive method study which employed quantitative techniques.  The study employed a social ecological model to investigate behavior of homeless via multiple levels of influences including intrapersonal, interpersonal, organizational, community and public policy. Surveys have been conducted on sixty-five homeless individuals.  Findings - It was found that support systems and structures should be derived from the whole streams from families, communities, organizations and government. Employment opportunities, long-term shelters within the community places and highly demanded skills are needed to improve their living condition. Research limitations - This study is only focused on the socio-economic structures of the homeless in a capital city. Originality/value - This is an empirical research using a social ecological model for the homeless in the Kuala Lumpur area. Research on homeless study has received little attention and has yet to be fully explored., Competing Interests: No competing interests were disclosed., (Copyright: © 2024 Mohd Rom NA et al.)

The divide between the rich and poor in the European housing market is fast rising. Latest research indicates that Europe is dealing with an increasing number of homeless people. Every city in Europe has them-homeless people compelled to live on street corners, frequently hiding themselves with cardboard. Rain, snow, and temperatures below zero pose a threat to their lives on a daily basis. There are many varied kinds of services that have been discovered, but it is difficult to keep track of everyone and guarantee that they have a warm night's sleep in the winter. The current article suggests accommodation as a workaround until they can receive high-intensity support, a way to keep a single person warm and safe during the winter. The focus is on devising a strategy that not only ensures the warmth and safety of individuals during the harsh winter months but also seeks to industrialize the construction of shelters, ensuring affordability below the cost of winter hospitalization for a homeless person. Crucially, the article introduces an additional layer to this initiative by highlighting the dual purpose of these individual shelters. Beyond being a means to provide respite for the homeless during severe weather, these shelters are envisioned as immediate response units in the event of emergencies such as earthquakes in urban areas. The article explores the potential impact of this multi-layered approach on transforming urban landscapes and fostering resilient communities., (© 2024. The Author(s).)

The term "revolving door patients" refers to those who are frequently rehospitalized for relapse. This phenomenon can be explained by a multitude of factors, including a lack of medical and/or social support. On the basis of a review of various modalities of psychiatric treatment, such as long-acting injectables, assisted outpatient treatment, and telehealth, it is clear that a major underlying issue among people with psychiatric diseases who lack insight into their mental and physical health is medication nonadherence. Therefore, we propose a mobile delivery program (MDP) in which health care professionals deliver medications and care to psychiatric patients in their own homes. The target patient population for MDP is patients with medication nonadherence, frequent emergency department visits, and missed appointments. Patients with mental illnesses, especially schizophrenia, are disproportionately represented among the homeless and incarcerated populations. By implementing MDP, we can help break the cycle of incarceration for patients with mental illnesses and homelessness. In addition, the cost of transportation and salaries for the mobile delivery team would be considerably lower than the billions of dollars spent each year due to relapses, emergency department visits, inpatient admissions, and crime leading to long-term stays in correctional facilities. This model has the potential to reduce relapse, improve functioning, and reduce excess morbidity and mortality. Substantial cost savings for health services can, in turn, be expected., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Third places-public and community settings like parks and libraries-are theorized to serve as sources of social connection, community, and play. Yet, young people who hold marginalized identities, such as those experiencing homelessness and housing instability, often endure discrimination in third place settings. This study used game-based inquiry to partner with recently housed young people who have experienced chronic housing instability (N = 21) to understand how they would (re)imagine future third places. We then analyzed transcripts from these game sessions through qualitative thematic analysis. Participants suggested that certain tenets must be present in third places: they must offer opportunities for agency and individualization; they must meet everyday needs; and they must be explicitly inclusive. To actualize these tenets, participants imagined places that meet many needs and do many things; portable and adaptable physical spaces; freedom to choose how to play; attending to and subverting oppressive social hierarchies; providing choice for privacy or connection; knowing people will be around; and free amenities. These findings have implications for theoretical development, practices in present and future third places, and methodological development of games in research., (© 2024 The Authors.

Background and Aims: Louse-borne Bartonella quintana infection and flea-borne murine typhus are two potentially serious vector-borne diseases that have led to periodic outbreaks among people experiencing homelessness in the United States. Little is known about louse- and flea-borne disease awareness and prevention among staff who provide services to the population. We surveyed staff in seven US states to identify gaps in knowledge and prevention practices for these diseases., Methods and Results: Surveys were administered to 333 staff at 89 homeless shelters and outreach teams in California, Colorado, Georgia, Maryland, Minnesota, New York and Washington from August 2022 to April 2023. Most participants (>68%) agreed that body lice and fleas are a problem for people experiencing homelessness. About half were aware that diseases could be transmitted by these vectors; however, most could not accurately identify which diseases. Less than a quarter of staff could describe an appropriate protocol for managing body lice or fleas. Misconceptions included that clients must isolate or be denied services until they are medically cleared., Conclusions: Our findings reveal significant knowledge gaps among staff who provide services to people experiencing homelessness in the prevention and control of louse- and flea-borne diseases. This demonstrates an urgent need for staff training to both reduce disease and prevent unnecessary restrictions on services and housing., (© 2024 Wiley‐VCH GmbH.

There are two dominant approaches to implementing permanent supportive housing (PSH), namely place-based (PB) and scattered-site (SS). Formal guidance does not distinguish between these two models and only specifies that PSH should be reserved for those who are most vulnerable with complex health needs. To consider both system- and self-selection factors that may affect housing assignment, this study applied the Gelberg-Anderson behavioral model for vulnerable populations to compare predisposing, enabling, and need factors among people experiencing homelessness (PE) by whether they were assigned to PB-PSH (n = 272) or SS-PSH (n = 185) in Los Angeles County during the COVID-19 pandemic. This exploratory, observational study also included those who were approved but did not receive PSH (n = 94). Results show that there are notable differences between (a) those who received PSH versus those who did not, and (b) those in PB-PSH versus SS-PSH. Specifically, PEH who received PSH were more likely to be white, US-born, have any physical health condition, and have lower health activation scores. PEH who received PB- versus SS-PSH were more likely to be older, Black, have any alcohol use disorder, and have higher health activation scores. These findings suggest that homeless service systems may consider PB-PSH more appropriate for PEH with higher needs but also raises important questions about how race may be a factor in the type of PSH that PEH receive and whether PSH is received at all., (© 2024.

In November 2021, two grassroots organizations in Boston, Massachusetts-a housing and health justice organization and a student-led nonprofit-established an initiative to provide persons experiencing homelessness (PEH) near the Massachusetts Avenue and Melnea Cass Boulevard ("Mass&Cass") intersection in Boston with access to free COVID-19 education and other wrap-around services. They partnered with hospitals, public health organizations, and advocacy groups to make this happen. This community-driven initiative serves as a model for how to enact a sustainable pipeline for PEH to receive health resources and information, with the voices of those directly impacted at the center.

Background: Young adult (18-30 years) people who inject drugs (PWID) face high hepatitis C virus (HCV) prevalence. In San Francisco, where >60% of PWID lack stable housing, barriers hinder HCV treatment access. We assessed progress towards the World Health Organization's (WHO) HCV elimination goal of an 80% reduction in incidence over 2015-2030, focusing on young (YPWID) and unstably housed PWID in San Francisco., Methods: We developed a dynamic HCV transmission model among PWID, parameterized and calibrated using bio-behavioural survey datasets from San Francisco. This included 2018 estimates for the antibody-prevalence among PWID (77%) and care cascade estimates for HCV for YPWID (72% aware of their status and 33% ever initiating treatment). Based on programmatic data, we assumed a 53.8% reduction in testing and 40.7% decrease in treatment from 2020 due to the COVID-19 pandemic, which partially rebounded from April 2021 with testing rates then being 31.1% lower than pre-pandemic rates and treatment numbers being 19.5% lower. We simulated different scenarios of how services changed after the pandemic to project whether elimination goals would be met., Results: Continuing post-pandemic rates of testing and treatment, the model projects an 83.3% (95% credibility interval [95% CrI]:60.6-96.9%) decrease in incidence among PWID over 2015-2030 to 1.5/100pyrs (95% CrI:0.3-4.4) in 2030. The probability of achieving the elimination goal by 2030 is 62.0%. Among YPWID and unstably housed PWID, the probability of achieving the elimination goal by 2030 is 54.8 and 67.6%, respectively. Importantly, further increasing testing and treatment rates to pre-pandemic levels by 2025 only results in a small increase in the probability (67.5%) of the elimination goal being achieved among all PWID by 2030, while increased coverage of medication for opioid use disorder among YPWID and/or housing interventions results in the probability of achieving elimination increasing to over 75%., Conclusion: The COVID-19 pandemic impeded progress toward achieving HCV elimination. Our findings indicate that existing partial rebounds in HCV testing and treatment may achieve the elimination goal by 2030, with an additional scale-up of interventions aimed at YPWID or unstably housed PWID ensuring San Francisco is likely to achieve elimination by 2030., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: P.V. received an unrestricted research grant from Gilead that is not related to this study.

In recent years, there has been increased interest in completing occupational therapy doctoral capstones with people experiencing homelessness. Given the complexity of practice with this population and its history of discrimination and marginalization, we argue for the development of guidelines for completing capstones in unhoused settings. In this column, we present background and contextual information, justification for the need for guidelines, and preliminary recommendations for consideration by students and faculty. Our aim is to invite reflection within the profession and among academic institutions and to promote dialogue with community agencies that serve this population to ensure that capstones are developed ethically, sustainably, and without unintentionally perpetuating harm., (Copyright © 2024 by the American Occupational Therapy Association, Inc.)

The role of housing as a social driver of health is well-established, with stable housing being an important factor in reducing health inequities. During developmentally critical periods such as young adulthood, unstable housing and related social marginalization have profound effects on development and later health, social, and economic wellbeing. This exploratory study analyzed data from a population-based, longitudinal sample of young adults (average age 31 years) from Washington State ( n = 755) to compare health and economic impacts of the early days of the COVID-19 pandemic, with a focus on housing status. Descriptive results suggest the pandemic exposed underlying vulnerabilities for young adults experiencing homelessness and housing instability, with an overall widening of inequities related to financial difficulties and increased risk for poor mental health and social isolation. Findings suggest that these vulnerabilities are magnified in the context of public health crises and strengthen the case for population-based studies investigating potential modifiable causes of housing instability to inform prevention and early intervention at the earliest possible point in a young person's development. Studies examining the severity of COVID-related hardships on young adult health and social outcomes are vital for establishing an evidence base for strategic policy action that seeks to prevent a rebound in young adult homelessness and housing instability post-pandemic. These studies would bolster both emergency preparedness responses that account for the unique needs of vulnerable populations and upstream population-level prevention approaches beginning long before the imminent risk for housing instability develops.

The COVID-19 pandemic, which brought about unprecedented changes globally, shed light on the significant disparities faced by persons experiencing homelessness (PEH). These individuals faced an elevated risk of contracting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) due to factors such as lack of safe housing, limited access to hygiene and sanitation, and communal living situations. The unique challenges, vulnerabilities, and effects of COVID-19 on PEH is discussed, as well as lessons learned from these experiences, recommendations for practitioners, and the ongoing implications for addressing homelessness., Competing Interests: Declaration of conflicting interestsThe author declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Logic modelling is used widely in health promotion planning for complex health and social problems. It is often undertaken collaboratively with stakeholders across sectors that hold and enact different institutional approaches. We use hermeneutic philosophy to explore how knowledge is 'lived' by - and unfolds differently for - cross-sectoral stakeholders during comprehensive primary healthcare service planning. An Organisational Action Research partnership was established with a non-government organisation designing comprehensive primary health care for individuals experiencing homelessness in Adelaide, Australia. Grey literature, stakeholder input, academic feedback, a targeted literature review and evidence synthesis were integrated in iterative cycles to inform and refine the logic model. Diverse knowledge systems are active when cross-sectoral stakeholders collaborate on logic models for comprehensive primary health care planning. Considering logic modelling as a hermeneutic praxis helps to foreground and explore these differences. In our case, divergent ideas emerged in how health/wellbeing and trust were conceptualised; language had different meanings across sectors; and the outcomes and data sought were nuanced for various collaborators. We explicate these methodological insights and also contribute our evidence-informed, collaboratively-derived model for design of a comprehensive primary health care service with populations experiencing homelessness. We outline the value of considering cross-sectoral logic modelling as hermeneutic praxis. Engaging with points of difference in cross-sectoral knowledge systems can strengthen logic modelling processes, partnerships and potential outcomes for complex and comprehensive primary health care services., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.
