Housing Status Changes Are Associated With Cancer Outcomes Among US Veterans.

Cancer is a leading cause of death in older unhoused adults. We assessed whether being unhoused, gaining housing, or losing housing in the year after cancer diagnosis is associated with poorer survival compared with being continuously housed. We examined all-cause survival in more than 100,000 veterans diagnosed with lung, colorectal, and breast cancer during the period 2011-20. Five percent were unhoused at the time of diagnosis, of whom 21 percent gained housing over the next year; 1 percent of veterans housed at the time of diagnosis lost housing. Continuously unhoused veterans and veterans who lost their housing had poorer survival after lung and colorectal cancer diagnosis compared with those who were continuously housed. There was no survival difference between veterans who gained housing after diagnosis and veterans who were continuously housed. These findings support policies to prevent and end homelessness in people after cancer diagnosis, to improve health outcomes.

Homelessness And Health: Factors, Evidence, Innovations That Work, And Policy Recommendations.

On a single night in 2023, more than 653,000 people experienced homelessness in the United States. In this overview, we highlight structural and individual risk factors that can lead to homelessness, explore evidence on the relationship between homelessness and health, discuss programmatic and policy innovations, and provide policy recommendations. Health system efforts to address homelessness and improve the health of homeless populations have included interventions such as screening for social needs and medical respite programs. Initiatives using the Housing First approach to permanent supportive housing have a strong track record of success. Health care financing innovations using Medicaid Section 1115 waivers offer promising new approaches to improving health and housing for people experiencing homelessness. To substantially reduce homelessness and its many adverse health impacts, changes are needed to increase the supply of affordable housing for households with very low incomes. Health care providers and systems should leverage their political power to advocate for policies that scale durable, evidence-based solutions to reduce homelessness, including increased funding to expand housing choice vouchers and greater investment in the creation and preservation of affordable housing.

Loneliness among homeless-experienced older adults with cognitive or functional impairments: qualitative findings from the HOPE HOME study.

BACKGROUND: Loneliness is more common in older adults and those who face structural vulnerabilities, including homelessness. The homeless population is aging in the United States; now, 48% of single homeless adults are 50 and older. We know little about loneliness among older adults who have experienced homelessness. We aimed to describe the loneliness experience among homeless-experienced older adults with cognitive and functional impairments and the individual, social, and structural conditions that shaped these loneliness experiences. METHODS: We purposively sampled 22 older adults from the HOPE HOME study, a longitudinal cohort study among adults aged 50 years or older experiencing homelessness in Oakland, California. We conducted in-depth interviews about participants perceived social support and social isolation. We conducted qualitative content analysis. RESULTS: Twenty participants discussed loneliness experience, who had a median age of 57 and were mostly Black (80%) and men (65%). We developed a typology of participants' loneliness experience and explored the individual, social, and structural conditions under which each loneliness experience occurred. We categorized the loneliness experience into four groups: (1) "lonely- distressed", characterized by physical impairment and severe isolation; (2) "lonely- rather be isolated", reflecting deliberate social isolation as a result of trauma, marginalization and aging-related resignation; (3) "lonely- transient", as a result of aging, acceptance and grieving; and (4) "not lonely"- characterized by stability and connection despite having experienced homelessness. CONCLUSIONS: Loneliness is a complex and heterogenous social phenomenon, with homeless-experienced older adults with cognitive or functional impairments exhibiting diverse loneliness experiences based on their individual life circumstances and needs. While the most distressing loneliness experience occurred among those with physical impairment and mobility challenges, social and structural factors such as interpersonal and structural violence during homelessness shaped these experiences.

Sleep Quality among Homeless-Experienced Older Adults: Exploratory Results from the HOPE HOME Study.

BACKGROUND: Sleep is essential to health and affected by environmental and clinical factors. There is limited longitudinal research examining sleep quality in homeless older adults. OBJECTIVE: To examine the factors associated with poor sleep quality in a cohort of older adults in Oakland, California recruited while homeless using venue-based sampling and followed regardless of housing status. DESIGN: Longitudinal cohort study. PARTICIPANTS: 244 homeless-experienced adults aged ≥ 50 from the Health Outcomes in People Experiencing Homelessness in Older Middle Age (HOPE HOME) cohort. MAIN MEASURES: We assessed sleep quality using the Pittsburgh Sleep Quality Index (PSQI). We captured variables via biannual questionnaires and clinical assessments. KEY RESULTS: Our sample was predominantly men (71.3%), Black (82.8%), and had a median age of 58.0 years old (IQR 54.0, 61.0). Two-thirds of participants (67.2%) reported poor sleep during one or more study visits; sleep duration was the worst rated subdomain. In a multivariable model, having moderate-to-severe depressive symptoms (AOR 2.03, 95% CI 1.40-2.95), trouble remembering (AOR 1.56, 95% CI 1.11-2.19), fair or poor physical health (AOR 1.49, 95% CI 1.07-2.08), two or more chronic health conditions (AOR 1.76, 95% CI 1.18-2.62), any ADL impairment (AOR 1.85, 95% CI 1.36-2.52), and being lonely (AOR 1.55, 95% CI 1.13-2.12) were associated with increased odds of poor sleep quality. Having at least one confidant was associated with decreased odds of poor sleep (AOR 0.56, 95% CI 0.37-0.85). Current housing status was not significantly associated with poor sleep quality. CONCLUSIONS: Homeless-experienced older adults have a high prevalence of poor sleep. We found that participants' physical and mental health was related to poor sleep quality. Poor sleep continued when participants re-entered housing. Access to physical and mental healthcare, caregiving support, and programs that promote community may improve homeless-experienced older adults sleep quality, and therefore, their overall health.

Barriers and Facilitators to Resolving Older Adult Homelessness through Stays with Family: Qualitative findings from the HOPE HOME Study.

Living with family and friends is a common strategy used to prevent or exit homelessness, but little is known about structural barriers that impede family and friends' ability to provide temporary or permanent housing for older homeless adults. We conducted semi-structured interviews with 46 homeless participants from the HOPE HOME study, a cohort of 350 community-recruited homeless adults age 50 or older in Oakland, CA, who reported having stayed with housed family/friends for 1 or more nights in the prior 6 months. We conducted semi-structured interviews with 19 hosts of homeless participants and 11 stakeholders in housing and homelessness. We found that homeless older adults and hosts perceived staying with family or friends as a form of temporary housing rather than as a permanent exit to homelessness. Structural barriers to family and friends providing housing for temporary stays or permanent exits from homelessness included housing regulations restricting visitors and changing rent obligations; decreased eligibility and priority for shelter and permanent housing; geographic and transportation challenges; and environments inconducive to older adults. We suggest four areas for policy reform: providing subsidies to hosts and homeless individuals, removing disincentives for homeless older adults to stay with family, changing lease regulations, and expanding the supply of affordable housing.

Housing Status, Cancer Care, and Associated Outcomes Among US Veterans.

Importance: Cancer is a leading cause of death among older people experiencing homelessness. However, the association of housing status with cancer outcomes is not well described. Objective: To characterize the diagnosis, treatment, surgical outcomes, and mortality by housing status of patients who receive care from the US Department of Veterans Affairs (VA) health system for colorectal, breast, or lung cancer. Design, Setting, and Participants: This retrospective cohort study identified all US veterans diagnosed with lung, colorectal, or breast cancer who received VA care between October 1, 2011, and September 30, 2020. Data analysis was performed from February 13 to May 9, 2023. Exposures: Veterans were classified as experiencing homelessness if they had any indicators of homelessness in outpatient visits, clinic reminders, diagnosis codes, or the Homeless Operations Management Evaluation System in the 12 months preceding diagnosis, with no subsequent evidence of stable housing. Main Outcomes and Measures: The major outcomes, by cancer type, were as follows: (1) treatment course (eg, stage at diagnosis, time to treatment initiation), (2) surgical outcomes (eg, length of stay, major complications), (3) overall survival by cancer type, and (4) hazard ratios for overall survival in a model adjusted for age at diagnosis, sex, stage at diagnosis, race, ethnicity, marital status, facility location, and comorbidities. Results: This study included 109 485 veterans, with a mean (SD) age of 68.5 (9.7) years. Men comprised 92% of the cohort. In terms of race and ethnicity, 18% of veterans were Black, 4% were Hispanic, and 79% were White. A total of 68% of participants had lung cancer, 26% had colorectal cancer, and 6% had breast cancer. There were 5356 veterans (5%) experiencing homelessness, and these individuals more commonly presented with stage IV colorectal cancer than veterans with housing (22% vs 19%; P = .02). Patients experiencing homelessness had longer postoperative lengths of stay for all cancer types, but no differences in other treatment or surgical outcomes were observed. These patients also demonstrated higher rates of all-cause mortality 3 months after diagnosis for lung and colorectal cancers, with adjusted hazard ratios of 1.1 (95% CI, 1.1-1.2) and 1.3 (95% CI, 1.2-1.4) (both P < .001), respectively. Conclusions and Relevance: In this large retrospective study of US veterans with cancer, homelessness was associated with later stages at diagnosis for colorectal cancer. Differences in lung and colorectal cancer survival between patients with housing and those experiencing homelessness were present but smaller than observed in other settings. These findings suggest that there may be important systems in the VA that could inform policy to improve oncologic outcomes for patients experiencing homelessness.

Loneliness among older adults who have experienced homelessness: qualitative findings from the HOPE HOME study.

The intersection of drug use discrimination and racial discrimination in the management of chronic non-cancer pain in United States primary care safety-net clinics: Implications for healthcare system and clinic-level changes.

BACKGROUND: Clinicians' bias related to patients' race and substance use history play a role in pain management. However, patients' or clinicians' understandings about discriminatory practices and the structural factors that contribute to and exacerbate these practices are underexamined. We report on perceptions of discrimination from the perspectives of patients with chronic non-cancer pain (CNCP) and a history of substance use and their clinicians within the structural landscape of reductions in opioid prescribing in the United States. METHODS: We interviewed 46 clinicians and 94 patients, using semi-structured interview guides, from eight safety-net primary care clinics across the San Francisco Bay Area from 2013 to 2020. We used a modified grounded theory approach to code and analyze transcripts. RESULTS: Clinicians discussed using opioid prescribing guidelines with the goals of increased opioid safety and reduced bias in patient monitoring. While patients acknowledged the validity of clinicians' concerns about opioid safety, they indicated that clinicians made assumptions about opioid misuse towards Black patients and patients suspected of substance use. Clinicians discussed evidence of discrimination in opioid prescribing at the clinic-wide level; racialized stereotypes about patients likely to misuse opioids; and their own struggles to overcome discriminatory practices regarding CNCP management. CONCLUSION: While clinicians and patients acknowledged opioid safety concerns, the practical application of opioid prescribing guidelines impacted how patients perceived and engaged with CNCP care particularly for patients who are Black and/or report a history of substance use. We recommend healthcare system and clinic-level interventions that may remediate discriminatory practices and associated disparities.

"I Needed for You to See What I'm Talking About": Experiences With Telehealth Among Homeless-Experienced Older Adults.

Little is known about how older adults with a current or recent experience of homelessness navigated the switch to telehealth during the COVID-19 pandemic. We examined the perceptions and use of telehealth in a purposive sample of 37 homeless-experienced older adults in mid-late 2020 through semi-structured qualitative interviews. We purposively recruited participants from a larger longitudinal study on homeless-experienced older adults in Oakland, CA. We subjected the data to content analysis. We found that most participants who used telehealth used audio-only phone calls for care. We found that (1) participants experienced challenges accessing the necessary technologies for telehealth, (2) perceptions of telehealth for physical health differed based on the modality (video vs. audio-only), and (3) participants had generally positive perceptions of telehealth for mental healthcare. Our findings suggest that clinicians interacting with homeless-experienced older adults should address the potential skepticism of audio-only telehealth patients, and assess their access to, and knowledge of, video conferencing technology.

Telehealth for management of chronic non-cancer pain and opioid use disorder in safety net primary care.

BACKGROUND: The SARS-CoV-2 (COVID-19) pandemic increased use of telehealth for the management of opioid use disorder and chronic non-cancer pain in primary care safety net clinical systems. Significant barriers to telehealth exist, little is known about how these barriers impact urban safety net, primary care providers and their patients. The objective of this study was to qualitatively assess the benefits and challenges of telehealth for management of chronic non-cancer pain, opioid use disorder, and multi-morbidity in primary care, safety net clinical systems. METHODS: We interviewed patients with chronic non-cancer pain and history of substance use (n = 22) and their primary care clinicians (n = 7) in the San Francisco Bay Area, March-July 2020. We recorded, transcribed, coded, and content analyzed interviews. RESULTS: COVID-19 shelter-in-place orders contributed to increases in substance use and uncontrolled pain, and posed challenges for monitoring opioid safety and misuse through telehealth. None of the clinics used video visits due to low digital literacy/access. Benefits of telehealth included decreased patient burden and missed appointments and increased convenience and control of some chronic conditions (e.g., diabetes, hypertension). Telehealth challenges included loss of contact, greater miscommunication, and less comprehensive care interactions. CONCLUSIONS: This study is one of the first to examine telehealth use in urban safety net primary care patients with co-occurring chronic non-cancer pain and substance use. Decisions to continue or expand telehealth should consider patient burden, communication and technology challenges, pain control, opioid misuse, and medical complexity.

Longitudinal Relationship Between Food Insecurity, Engagement in Care, and ART Adherence Among US Women Living with HIV.

Food insecurity disproportionately affects people with HIV and women in the United States (US). More evidence is needed to understand the interplay between levels of food insecurity and levels of antiretroviral therapy (ART) adherence over time, as well as how food insecurity relates to engagement in HIV care. We used random effects models with longitudinal data from the US Women's Interagency HIV Study to estimate the (1) adjusted associations of current and 6-month lagged food security with ART adherence categories (n = 1646), and (2) adjusted associations of food security with engagement-in-care (n = 1733). Very low food security was associated with a higher relative risk of ART non-adherence at prior and current visits compared with food security, and this association increased across non-adherence categories. Very low food security was associated with lower odds of receiving HIV care and higher odds of a missed visit. Food insecurity among US women with HIV is associated with poorer engagement in care and degree of ART non-adherence over time.

Using behavioral theory to adapt advance care planning for homeless-experienced older adults in permanent supportive housing.

BACKGROUND: Older adults experiencing chronic homelessness (i.e., prolonged homelessness and a disabling condition) have low rates of advance care planning (ACP) despite high rates of morbidity and mortality. Rehousing of homeless-experienced individuals into permanent supportive housing (PSH) may present an opportunity to introduce ACP; but this is unknown. Therefore, we explored staff and resident perceptions of conducting ACP in PSH. METHODS: We conducted semi-structured interviews with PSH staff (n = 13) and tenants (PSH residents) (n = 26) in San Francisco. We used the capability (C), opportunity (O), motivation (M), behavior (COM-B) framework within the Behavior Change Wheel model and the Theoretical Domains Framework (TDF) to inform interviews, categorize themes, and guide qualitative thematic analysis. RESULTS: The mean age of PSH residents was 67 (SD = 6.1) years and 52% were women. Of staff, 69% were women. Important COM-B barriers included ACP complexity (C), complicated relationship dynamics (O), resource limitations (O), pessimism (M), variable staff confidence (M), and competing priorities (M). Facilitators included easy-to-use documents/videos, including the PREPARE for Your Care program (C), stability with housing (O), exposure to health crises (O), potential for strong relationships (O), and belief that ACP is impactful (M). Recommendations included adapting materials to the PSH setting, providing staff trainings/scripts, and using optional one-on-one or group sessions. CONCLUSIONS: We identified behavioral determinants related to ACP for formerly chronically homeless older adults in PSH. Future interventions should include using easy-to-use ACP materials and developing resources to educate PSH residents, train staff, and model ACP in groups or one-on-one sessions.

Tobacco use behaviors and views on engaging in clinical trials for tobacco cessation among individuals who experience homelessness.

Background: Clinical trials that include contingency management for smoking cessation have shown promising results for short-term quitting, but none have explored this approach for long-term abstinence in people experiencing homelessness. We designed a clinical trial of an extended contingency management intervention for smoking cessation for people experiencing homelessness. This study has two aims: (1) to explore tobacco use behaviors, and views toward smoking cessation, and (2) to explore factors influencing acceptability of engaging in such a trial in a sample of adult smokers experiencing homelessness. Methods: We administered a questionnaire to obtain information on tobacco use behaviors and conducted in-depth, semi-structured interviews with 26 patients who had experienced homelessness and were patients at a safety net health clinic in San Francisco, California, where we planned to pilot the intervention. We obtained information on triggers for tobacco use, prior cessation experiences, attitudes toward cessation, attitudes toward engaging in a clinical trial for cessation, and factors that might influence participation in our proposed contingency management clinical trial. We analyzed transcripts using content analysis. Results: Participants described the normative experiences of smoking, co-occurring substance use, and the use of tobacco to relieve stress as barriers to quitting. Despite these barriers, most participants had attempted to quit smoking and most were interested in engaging in a clinical trial as a method to quit smoking. Participants noted that desirable features of the trial include: receiving financial incentives to quit smoking, having a flexible visit schedule, having the study site be easily accessible, and having navigators with lived experiences of homelessness. Conclusion: A patient-centric clinical trial design that includes incentives, flexible visits and navigators from the community may increase feasibility of engaging in clinical trials among individuals experiencing homelessness.

Cluster Analysis of the Highest Users of Medical, Behavioral Health, and Social Services in San Francisco.

BACKGROUND: In the City and County of San Francisco, frequent users of emergent and urgent services across different settings (i.e., medical, mental health (MH), substance use disorder (SUD) services) are referred to as high users of multiple systems (HUMS). While often grouped together, frequent users of the health care system are likely a heterogenous population composed of subgroups with differential management needs. OBJECTIVE: To identify subgroups within this HUMS population using a cluster analysis. DESIGN: Cross-sectional study of HUMS patients for the 2019-2020 fiscal year using the Coordinated Care Management System (CCMS), San Francisco Department of Public Health's integrated data system. PARTICIPANTS: We calculated use scores based on nine types of urgent and emergent medical, MH, and SUD services and identified the top 5% of HUMS patients. Through k-medoids cluster analysis, we identified subgroups of HUMS patients. MAIN MEASURES: Subgroup-specific demographic, comorbidity, and service use profiles. KEY RESULTS: The top 5% of HUMS patients in the study period included 2657 individuals; 69.7% identified as men and 66.5% identified as non-White. We detected 5 subgroups: subgroup 1 (N = 298, 11.2%) who were relatively younger with prevalent MH and SUD comorbidities, and MH services use; subgroup 2 (N = 478, 18.0%), who were experiencing homelessness, with multiple comorbidities, and frequent use of medical services; subgroup 3 (N = 449, 16.9%), who disproportionately self-identified as Black, with prolonged homelessness, multiple comorbidities, and persistent HUMS status; subgroup 4 (N = 690, 26.0%), who were relatively older, disproportionately self-identified as Black, with prior homelessness, multiple comorbidities, and frequent use of medical services; and subgroup 5 (N=742, 27.9%), who disproportionately self-identified as Latinx, were housed, with medical comorbidities and frequent medical service use. CONCLUSIONS: Our study highlights the heterogeneity of HUMS patients. Interventions must be tailored to meet the needs of these diverse patient subgroups.

Accounting for the interplay of interpersonal and structural trauma in the treatment of chronic non-cancer pain, opioid use disorder, and mental health in urban safety-net primary care clinics.

While the epidemiological literature recognizes associations between chronic non-cancer pain (CNCP), opioid use disorder (OUD), and interpersonal trauma stemming from physical, emotional, sexual abuse or neglect, the complex etiologies and interplay between interpersonal and structural traumas in CNCP populations are underexamined. Research has documented the relationship between experiencing multiple adverse childhood experiences (ACEs) and the likelihood of developing an OUD as an adult. However, the ACEs framework is criticized for failing to name the social and structural contexts that shape ACE vulnerabilities in families. Social scientific theory and ethnographic methods offer useful approaches to explore how interpersonally- and structurally-produced traumas inform the experiences of co-occurring CNCP, substance use, and mental health. We report findings from a qualitative and ethnographic longitudinal cohort study of patients with CNCP (n = 48) who received care in safety-net settings and their primary care providers (n = 23). We conducted semi-structured interviews and clinical and home-based participant observation from 2018 to 2020. Here we focus our analyses on how patients and providers explained and situated the role of patient trauma in the larger clinical context of reductions in opioid prescribing to highlight the political landscape of the United States opioid overdose crisis and its impact on clinical interactions. Findings reveal the disproportionate burden structurally-produced, racialized trauma places on CNCP, substance use and mental health symptoms that shapes patients' embodied experiences of pain and substance use, as well as their emotional experiences with their providers. Experiences of trauma impacted clinical care trajectories, yet providers and patients expressed limited options for redress. We argue for an adaptation of trauma-informed care approaches that contextualize the structural determinants of trauma and their interplay with interpersonal experiences to improve clinical care outcomes.

Community Supervision, Housing Insecurity, & Homelessness.

In recent decades, the United States has seen the simultaneous rise of mass incarceration and homelessness. The two crises interact with and worsen one another. Mass incarceration and homelessness are driven by the same structural factors and exacerbate one another in a feedback loop. People on community supervision face many barriers to housing, putting them at high risk of experiencing homelessness in the months following release. People experiencing homelessness are at heightened risk of criminal justice involvement, including violating the terms of their community supervision, for engaging in survival behaviors in public spaces. This paper presents evidence-based approaches to improving housing strategies for reentry populations, preventing homelessness among those in community supervision, and rehousing members of the reentry community experiencing homelessness. It concludes with recommendations for policymakers interested in improving housing outcomes and overall reentry success for people on community supervision.

Contingency management to promote smoking cessation in people experiencing homelessness: Leveraging the electronic health record in a pilot, pragmatic randomized controlled trial.

BACKGROUND: Cigarette smoking is disproportionately high among people experiencing homelessness (PEH). Contingency management (CM) is a strategy that has shown considerable efficacy for smoking cessation and has been used in short-term studies of smoking abstinence in PEH. We describe a pilot, pragmatic randomized controlled trial protocol, which leverages an electronic health record (EHR) infrastructure to assess the feasibility and acceptability of an extended CM intervention to improve long-term abstinence in PEH. METHODS: We will conduct the study at three safety-net clinics in San Francisco among 90 adults experiencing homelessness who smoke cigarettes currently and have a desire to quit. We will encourage all participants to receive smoking cessation services that include behavioral counseling and pharmacotherapy through their clinics. We will randomly assign participants to an extended CM intervention group with escalating incentives contingent on abstinence or to a control group with fixed incentives for attending study visits. We will use the EHR to recruit participants, track receipt of counseling and pharmacotherapy during clinical care, and communicate with providers on participants' progress. CM participants will get escalating incentives for demonstration of carbon monoxide-verified abstinence over 6 months, with a total possible earnings of $475. Control participants will receive a fixed incentive of $5 for attending study visits, totaling $125. We will conduct the carbon-monoxide verified abstinence assessments-which will determine CM incentive amounts-daily during week 1, bi-weekly through week 4, weekly through week 13, and monthly through week 24. Measures of feasibility and acceptability, both quantitative and qualitative, will include assessments of screening and recruitment, adherence to study visits, engagement in smoking cessation clinical care, retention, and participant satisfaction. One of the primary clinical outcomes will be biochemically verified 7-day point prevalence abstinence at 6 months. We will measure secondary outcomes, which will include 7-day point prevalence abstinence at 2 weeks, 3 and 12 months. DISCUSSION: This trial will allow us to assess the feasibility and acceptability of a CM cessation intervention among PEH. The protocol's clinical setting and use of EHRs gives it significant potential for scalability. If found to be feasible, acceptable, and subsequently efficacious in a larger trial, the intervention could reduce tobacco-related health disparities by increasing long-term smoking abstinence among this vulnerable population. TRIAL REGISTRATION: ClinicalTrials.gov NCT04982952. Registered on July 29, 2021.

The smoke-free home study: study protocol for a cluster randomized controlled trial of a smoke-free home intervention in permanent supportive housing.

BACKGROUND: Formerly chronically homeless adults who live in permanent supportive housing (PSH) have high prevalence of smoking. It is uncommon to find smoke-free policies in PSH because of the concern that such policies contradict PSH's harm reduction framework and could increase homelessness should residents lose their housing because of the policy. However, in the absence of such policies, non-smoking PSH residents face the harmful effects of secondhand smoke exposure while residents who smoke see increased risks from high rates of smoking throughout their residence. Our pilot work highlighted the feasibility and acceptability of an intervention designed to promote voluntary adoption of a smoke-free home. Here we report a protocol for a cluster randomized controlled trial of the smoke-free home intervention for formerly chronically homeless residents in PSH. METHODS: The smoke-free home intervention provides face-to-face counseling and instruction to PSH residents on how to adopt a smoke-free home and offers training for PSH staff on how to refer residents to tobacco cessation services. We will randomize 20 PSH sites in the San Francisco Bay Area to either the intervention or wait-list control arms. We will enroll 400 PSH residents who smoke cigarettes in their housing unit and 120 PSH staff who work at the sites. At baseline, three- and six-months follow-up, we will ask residents to report their tobacco use and cessation behaviors and adoption of smoke-free homes. We will ask staff to answer questions on their knowledge, attitudes, practices, and barriers related to supporting residents' smoking cessation. The primary outcome for PSH residents is adoption of smoke-free homes for 90 days or more at six-months follow-up, and the secondary outcome is point prevalence tobacco abstinence. The primary outcome for PSH staff is change in Smoking Knowledge Attitudes Practices survey score. DISCUSSION: Voluntary adoption of smoke-free homes is a promising approach for reducing exposure to secondhand smoke and reducing tobacco use among a population facing high rates of tobacco-related disease, and is aligned with PSH's harm reduction framework. Findings from this study have the potential to inform adoption of tobacco control policies among vulnerable populations most at risk for smoking-related harms. TRIAL REGISTRATION: This study was registered with the U.S. National Institute of Health Clinical Trials register on April 22, 2021: NCT04855357.

Barriers to Colorectal Cancer Screening and Surveillance in Homeless Patients: A Case Report and Policy Recommendations.

Patients experiencing homelessness face significant barriers to screening and treatment for colorectal cancer, leading to worse outcomes. In this perspective, we use an exemplar patient case to highlight potential policy solutions for reducing this health care disparity by increasing access to early detection and treatment in this population.
