A cross-sectional observational study of unmet health needs among homeless and vulnerably housed adults in three Canadian cities

Perceived Unmet Need for Care and Barriers to Care Among Individuals with Mental Health Issues: A Meta-analysis

Unmet needs refer to the gap between the health services individuals require and what they receive. Individuals with mental health issues often face barriers preventing them from accessing the care they need. A meta-analysis was conducted to estimate the pooled prevalence of unmet needs for care and barriers to care among individuals with mental health issues. The databases PubMed, Scopus, Web of Science, and Cochrane Library were searched for relevant studies published from December 1, 1985 to August 1, 2024. Following the screening process, 204 included studies remained for meta-analysis. Individuals with mental health issues reported significant pooled prevalence rate of unmet care needs over the past year, with the most common being related to work/occupation (43%), dental care (41%), counseling (40%), social intervention (37%), mental health (34%), physical health needs (33%), skills training (32%), social network (32%), psychological distress (31%), information (27%), intimate relationships (27%), benefits (26%), harm reduction (25%), psychotic symptoms (24%), housing (24%), money and food (21%), education (20%), sexual expression (19%), home care (16%), safety (15%), self-care (15%), telephone support (9%), and child care (8%). The pooled prevalence rates of barriers to accessing care were motivational (38%), structural (37%), financial (31%), and stigmatization (25%). The findings indicated that patients with substance use disorders experienced a significantly higher prevalence of unmet care needs and barriers to accessing care compared to those with mental health disorders and homeless individuals. The results showed that unmet care needs were highest among those in established adulthood, while harm reduction was more common among adolescents and emerging adults. Physical health and food needs were most prevalent among midlife adults. Barriers to care were most common among adolescents and emerging adults, except for structural barriers, which were most frequent among midlife adults. To address the unmet employment needs of Individuals with mental health issues, comprehensive training in essential skills is recommended. Enhancing dentists' mental health understanding and fostering collaboration among healthcare providers is crucial. Government-funded, low-barrier service models for substance use disorder patients is suggested to enhance accessibility and effectiveness, while improving health service affordability and acceptability is essential.

Cognitive Correlates of Resilience in Adults Experiencing Homelessness

OBJECTIVE

In adults who have experienced homelessness, greater psychological resilience is related to better quality of life, community functioning, and social cognition. Domain-specific cognitive functioning is positively associated with resilience in housed populations; however, these relationships have yet to be explored among adults experiencing homelessness. The aim of this study is to examine the relationships between domain-specific cognitive function and psychological resilience among adults experiencing homelessness.

METHOD

One hundred and six adults who have experienced homelessness were recruited in Toronto, Canada, and 88 were included in analyses (51% female, mean age = 43 years). Study measures assessed psychological resilience as well as domain-specific cognition (vocabulary, oral reading, processing speed, episodic memory, and executive functioning) using the NIH Toolbox Cognition Battery. Additional covariates of interest included psychological distress, social network size, substance misuse, and major psychiatric disorders. Hierarchical regression modeling explored the contributions of each cognitive domain to resilience while accounting for established covariates.

RESULTS

Oral reading was positively associated with higher resilience, explaining 12.45% of the variance in resilience while controlling for age, education, gender, substance misuse, psychological distress, and social network size. Performance on measures of executive functioning, processing speed, and visual memory were not found to be related to self-reported resilience.

CONCLUSION

The results suggest that verbal vocabulary, shaped by the accumulation of experiences across one's lifetime, may be an important contributor to psychological resilience. Better crystallized abilities may reflect more enriched early life experiences that are critical to better coping skills and well-being of adults experiencing homelessness.

A National Mobile Medical Unit (MMU) Program to Address the Healthcare Needs of Veterans Experiencing Homelessness: An Evaluation Protocol

Background

Homelessness remains a public health concern in the United States (U.S.) and ending veteran homelessness has been a significant priority for the U.S. Department of Veterans Affairs (VA) for over a decade. However, veterans experiencing homelessness (VEH) have unmet healthcare needs and face numerous barriers to accessing and engaging in healthcare.

Objectives

The Veterans Health Administration's (VHA) Homeless Programs Office (HPO) implemented mobile medical units (MMUs) within the tailored primary care model established in 2011 called the Homeless Patient Aligned Care Team (HPACT) program to expand access to care for hard-to-reach VEH. This article outlines the evaluation protocol for the HPACT MMU program to examine the impact of MMUs on engaging and retaining homeless veterans in VA primary care and other supportive services.

Design

Using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework, we will assess how mobile services engage VEH in VA primary care and preventive care. This 4-year program evaluation includes a plan to collect individual and organizational level quantitative and qualitative data.

Discussion

The first stages of program adoption and implementation have been completed resulting in 25 MMUs being deployed across the U.S. that are fully operational and ready to serve VEH. Early outcomes demonstrate the significant impact of the ability MMUs in reducing barriers such as transportation for VEH, while increasing positive veteran health outcomes.

Conclusion

This evaluation will provide insight on the innovative ways in which mobile medical units (MMUs) may expand the boundaries of the VA and external health care systems in efforts to improve health equity and access among our most vulnerable populations. Preliminary outcomes show significant engagement with VEH in the community and interest in the model of care. The program has the potential to play an essential role in achieving VA's goal of ending veteran homelessness.

Social determinants of unmet need for primary care: a systematic review

BACKGROUND

Despite primary care being largely free at the point of delivery, many Canadians experience challenges in accessing the services they need. A systematic review was conducted to summarize the evidence on the level of unmet need for primary care in Canada and its social determinants.

METHODS

MEDLINE, Embase, Cochrane, and Web of Science databases were screened from inception to December 2023 using relevant search terms for primary care and unmet healthcare needs. Quantitative observational studies in the English language that included Canadian adults aged 18 years and older and focused on unmet needs for primary care were included. The risk of bias in the studies was assessed using either the Joanna Briggs Institute (JBI) critical appraisal checklist or the Newcastle-Ottawa Scale. The included studies were synthesized narratively.

RESULTS

Forty-six studies met the inclusion criteria for this review. Of the included studies, 96% were cross-sectional in design and 91% had low risk of bias. The prevalence of unmet need, mostly self-reported, varied between 6.6% and 25.2% in national studies. Social determinants of unmet needs were heterogeneous across studies. Findings suggest that unmet need for primary care is related to having low income, mental health diagnoses, and chronic conditions, and negatively associated with older age, having better-perceived health, and having a family physician.

CONCLUSIONS

Universal access to primary care is the founding principle of the Canadian healthcare system. However, we found evidence suggesting that the extent to which primary care needs are met is influenced by social determinants of health. Further research is needed to improve our understanding of the mechanisms of unmet primary care needs in Canada.

Homelessness and mortality: gender, age, and housing status inequity in Korea

OBJECTIVES

We compared mortality rates among various housing statuses within the homeless population and investigated factors contributing to their deaths, including housing status, gender, and age.

METHODS

Using a comprehensive multi-year dataset (n=15,445) curated by the National Tuberculosis Screening and Case Management Programs, matched with the 2019-2021 Vital Statistics Death Database and National Health Insurance claims data, we calculated age-standardized mortality rates and conducted survival analysis to estimate differences in mortality rates based on housing status.

RESULTS

The mortality rate among the homeless population was twice as high as that of the general population, at 1,159.6 per 100,000 compared to 645.8 per 100,000, respectively. Cancer and cardiovascular diseases were the primary causes of death. Furthermore, individuals residing in shelter facilities faced a significantly higher risk of death than those who were rough sleeping, with an adjusted hazard ratio of 1.70 (95% confidence interval, 1.37 to 2.11). This increased risk was especially pronounced in older adults and women.

CONCLUSIONS

The study highlights the urgent need for targeted interventions, as the homeless population faces significantly higher mortality rates. Older adults and women in shelter facilities are at the highest risk.

The Impact of Race and Sex on the Clinical Outcomes of Homeless Patients With Alcoholic Liver Disease: Propensity Score Matched Analysis of US Hospitals

BACKGROUND

Among patients with alcoholic liver disease (ALD), homelessness poses significant medical and psychosocial risks; however, less is known about the effects of race and sex on the hospital outcomes of admitted homeless patients with ALD.

METHODS

The National Inpatient Sample database from 2012 to 2017 was used to isolate homeless patients with ALD, and the cohort was further stratified by race and sex for comparisons. Propensity score matching was utilized to minimize covariate confounding. The primary endpoints of this study include mortality, hospital length of stay, and hospital costs; secondary endpoints included the incidence of liver complications.

RESULTS

There were 3972 females/males postmatch, as well as 2224 Blacks/Whites and 4575 Hispanics/Whites postmatch. In multivariate, there were no significant differences observed in mortality rate, length of stay, and costs between sexes. Comparing liver outcomes, females had a higher incidence of hepatic encephalopathy [adjusted odds ratio (aOR) 1.02, 95% CI: 1.01-1.04, P <0.001]. In comparing Blacks versus Whites, Black patients had higher hospitalization costs (aOR 1.13, 95% CI: 1.03-1.24, P =0.01); however, there were no significant differences in mortality, length of stay, or liver complications. In comparing Hispanics versus Whites, Hispanic patients had longer length of hospital stay (aOR 1.12, 95% CI: 1.06-1.19, P <0.001), greater costs (aOR 1.15, 95% CI: 1.09-1.22, P <0.001), as well as higher prevalence of liver complications including varices (aOR 1.04, 95% CI: 1.02-1.06, P <0.001), hepatic encephalopathy (aOR 1.03, 95% CI: 1.02-1.04, P <0.001), and hepatorenal syndrome (aOR 1.01, 95% CI 1.00-1.01, P =0.03). However, there was no difference in mortality between White and Hispanic patients.

CONCLUSIONS

Black and Hispanic ALD patients experiencing homelessness were found to incur higher hospital charges; furthermore, Hispanic patients also had greater length of stay and higher incidence of liver-related complications compared with White counterparts.

Cardiometabolic risk factors in social housing residents: A multi-site cross-sectional survey in older adults from Ontario, Canada

OBJECTIVE

This study describes cardiometabolic diseases and related risk factors in vulnerable older adults residing in social housing, aiming to inform primary care initiatives to reduce health inequities. Associations between sociodemographic variables, modifiable risk factors (clinical and behavioural), health-related quality of life and self-reported cardiometabolic diseases were investigated.

DESIGN, SETTING, AND PARTICIPANTS

This was a cross-sectional study with an interviewer-administered questionnaire. Data was collected from residents aged 55 years and older residing in 30 social housing apartment buildings in five regions in Ontario, Canada.

OUTCOME MEASURES

The proportion of cardiometabolic diseases and modifiable risk factors (e.g., clinical, behavioural, health status) in this population was calculated.

RESULTS

Questionnaires were completed with 1065 residents: mean age 72.4 years (SD = 8.87), 77.3% were female, 87.2% were white; 48.2% had less than high school education; 22.70% self-reported cardiovascular disease (CVD), 10.54% diabetes, 59.12% hypertension, 43.59% high cholesterol. These proportions were higher than the general population. Greater age was associated with overweight, high cholesterol, high blood pressure and CVD. Poor health-related quality of life was associated with self-reported CVD and diabetes.

CONCLUSIONS

Older adults residing in social housing in Ontario have higher proportion of cardiovascular disease and modifiable risk factors compared to the general population. This vulnerable population should be considered at high risk of cardiometabolic disease. Primary care interventions appropriate for this population should be implemented to reduce individual and societal burdens of cardiometabolic disease.

"Whatever journey you want to take, I'll support you through": a mixed methods evaluation of a peer worker program in the hospital emergency department

BACKGROUND

People who are unhoused, use substances (drugs and/or alcohol), and who have mental health conditions experience barriers to care access and are frequently confronted with discrimination and stigma in health care settings. The role of Peer Workers in addressing these gaps in a hospital-based context is not well characterized. The aim of this evaluation was to 1) outline the role of Peer Workers in the care of a marginalized populations in the emergency department; 2) characterize the impact of Peer Workers on patient care, and 3) to describe how being employed as a Peer Worker impacts the Peer.

METHODS

Through a concurrent mixed methods evaluation, we explore the role of Peer Workers in the care of marginalized populations in the emergency department at two urban hospitals in Toronto, Ontario Canada. We describe the demographic characteristics of patients (n = 555) and the type of supports provided to patients collected through a survey between February and June 2022. Semi-structured, in-depth interviews were completed with Peer Workers (n = 7). Interviews were thematically analyzed using a deductive approach, complemented by an inductive approach to allow new themes to emerge from the data.

RESULTS

Support provided to patients primarily consisted of friendly conversations (91.4%), discharge planning (59.6%), tactics to help the patient navigate their emotions/mental wellbeing (57.8%) and sharing their lived experience (50.1%). In over one third (38.9%) of all patient interactions, Peer Workers shared new information about the patient with the health care team (e.g., obtaining patient identification). Five major themes emerged from our interviews with Peer Workers which include: (1) Establishing empathy and building trust between the patient and their care team through self-disclosure; (2) Facilitating a person-centered approach to patient care through trauma-informed listening and accessible language; (3) Support for patient preferences on harm reduction; (4) Peer worker role facilitating self-acceptance and self-defined recovery; and (5) Importance of supports and resources to help Peer Workers navigate the emotional intensity of the emergency department.

CONCLUSIONS

The findings add to the literature on Peer Worker programs and how such interventions are designed to best meet the needs of marginalized populations.

Nutritional needs, resources, and barriers among unhoused adults cared for by a street medicine organization in Chicago, Illinois: a cross-sectional study

BACKGROUND

Those experiencing houselessness rely on obtaining food from community organizers and donations. Simultaneously, the houseless face disproportionally high rates of medical conditions that may be affected by diet including diabetes, hypertension, and hyperlipidemia. There is limited literature on the resources and barriers of the houseless community regarding optimal nutrition from an actionable perspective. Further, less data is available on how street medicine organizations may best impact the nutrition of the unhoused they serve. Elucidating this information will inform how organizational efforts may best support the nutrition of the houseless community.

METHODS

In partnership with the medical student-run organization, Chicago Street Medicine, at Northwestern University Feinberg School of Medicine, twenty adults experiencing houselessness in Chicago, Illinois participated in the cross-sectional study. A 10-item survey was verbally administered to characterize the participants' daily food intake, food sources, barriers, resources, and nutritional preferences and needs. All data was directly transcribed into REDCap. Descriptive statistics were generated.

RESULTS

Individuals consumed a median of 2 snacks and meals per day (IQR: 1-3). No participant consumed adequate servings of every food group, with only one participant meeting the dietary intake requirements for one food group. Participants most often received their food from donations (n = 15), purchasing themselves (n = 11), food pantries (n = 4), and shelters (n = 3). Eleven of nineteen participants endorsed dental concerns as a major barrier to consuming certain foods. Twelve participants had access to a can opener and twelve could heat their meals on a stove or microwave. Seven had access to kitchen facilities where they may prepare a meal. Approximately half of participants had been counseled by a physician to maintain a particular diet, with most related to reducing sugar intake.

CONCLUSION

Most houseless participants were unable to acquire a balanced diet and often relied on organizational efforts to eat. Organizations should consider the chronic health conditions, dentition needs, and physical resources and barriers to optimal nutrition when obtaining food to distribute to the unhoused.

How do health system factors (funding and performance) impact on access to healthcare for populations experiencing homelessness: a realist evaluation

BACKGROUND

People experiencing long-term homelessness face significant difficulties accessing appropriate healthcare at the right time and place. This study explores how and why healthcare performance management and funding arrangements contribute to healthcare accessibility or the lack thereof using long-term homeless adults as an example of a population experiencing social exclusion.

METHODS

A realist evaluation was undertaken. Thirteen realist interviews were conducted after which data were transcribed, coded, and analysed.

RESULTS

Fourteen CMOCs were created based on analysis of the data collected. These were then consolidated into four higher-level CMOCs. They show that health systems characterised by fragmentation are designed to meet their own needs above the needs of patients, and they rely on practitioners with a special interest and specialised services to fill the gaps in the system. Key contexts identified in the study include: health system fragmentation; health service fragmentation; bio-medical, one problem at a time model; responsive specialised services; unresponsive mainstream services; national strategy; short health system funding cycles; and short-term goals.

CONCLUSION

When health services are fragmented and complex, the needs of socially excluded populations such as those experiencing homelessness are not met. Health systems focus on their own metrics and rely on separate actors such as independent NGOs to fill gaps when certain people are not accommodated in the mainstream health system. As a result, health systems lack a comprehensive understanding of the needs of all population groups and fail to plan adequately, which maintains fragmentation. Policy makers must set policy and plan health services based on a full understanding of needs of all population groups.

Cognitive determinants of community functioning and quality of life in homeless adults with mental illness: 6-year follow-up from the At Home/Chez Soi Study Toronto site

BACKGROUND

High rates of physical and mental health comorbidities are associated with functional impairment among persons who are homeless. Cognitive dysfunction is common, but how it contributes to various functional outcomes in this population has not been well investigated. This study examines how cognition covaries with community functioning and subjective quality of life over a 6-year period while accounting for the effects of risk and protective factors.

METHODS

Participants were 349 homeless adults (mean age = 39.8) recruited from the Toronto site of the At Home/Chez Soi study, a large Canadian randomized control trial of Housing First. Participants completed up to four clinical evaluations over 6 years. Factor scores were created to index verbal learning and memory (vLM) and processing speed-cognitive flexibility (PSCF). The primary outcomes were community functioning and subjective quality of life. Risk factors included lifetime homelessness, mental health diagnoses, medical comorbidity, and childhood adversity. Linear mixed-effects models were conducted to examine cognition-functional outcome associations over time, with resilience as a moderator.

RESULTS

Better vLM (b = 0.787, p = 0.010) and PSCF (b = 1.66, p < 0.001) were associated with better community functioning, but not with quality of life. Resilience conferred a protective effect on subjective quality of life (b = 1.45, p = 0.011) but did not moderate outcomes.

CONCLUSIONS

Our findings suggest a need to consider the unique determinants of community functioning and quality of life among homeless adults. Cognition should be prioritized as a key intervention target within existing service delivery models to optimize long-term functional outcomes.

Unmet health care needs during the COVID-19 pandemic among adults: a prospective cohort study in the Canadian Longitudinal Study on Aging

BACKGROUND

The COVID-19 pandemic affected access to health care services in Canada; however, limited research examines the influence of the social determinants of health on unmet health care needs during the first year of the pandemic. The objectives of this study were to describe unmet health care needs during the first year of the pandemic and to investigate the association of unmet needs with the social determinants of health.

METHODS

We conducted a prospective cohort study of 23 972 adults participating in the Canadian Longitudinal Study on Aging (CLSA) COVID-19 Study (April-December 2020) to identify the social determinants of health associated with unmet health care needs during the pandemic. Using logistic regression, we assessed the association between several social determinants of health on the following 3 outcomes (separately): experiencing any challenges in accessing health care services, not going to a hospital or seeing a doctor when needed, and experiencing barriers to accessing testing for SARS-CoV-2 infection.

RESULTS

From September to December 2020, 25% of participants experienced challenges accessing health care services, 8% did not go to a hospital or see a doctor when needed and 4% faced barriers accessing testing for SARS-CoV-2 infection. The prevalence of all 3 unmet need outcomes was lower among older age groups. Differences were observed by sex, region, education, income and racial background. Immigrants (odds ratio [OR] 1.18, 95% confidence interval [CI] 1.09-1.27) or people with chronic conditions (OR 1.35, 95% CI 1.27-1.43) had higher odds of experiencing challenges accessing health care services and had higher odds of not going to a hospital or seeing a doctor (immigrants OR 1.26, 95% CI 1.11-1.43; chronic conditions OR 1.45, 95% CI 1.31-1.61). Prepandemic unmet health care needs were strongly associated with all 3 outcomes.

INTERPRETATION

Substantial unmet health care needs were reported by Canadian adults during the first year of the pandemic. The results of this study have important implications for health equity.

Determinants of COVID-19 vaccine acceptance and access among people experiencing homelessness in Germany: A qualitative interview study

Introduction

People experiencing homelessness face lower life expectancy, higher prevalence of somatic and mental diseases and a more difficult access to healthcare compared to people in secure living. During the COVID-19 pandemic transmission rates were higher among people experiencing homelessness and preventive public health measures were not properly adapted to the specific needs of people experiencing homelessness. Thus, goal of our study was understanding the determinants of acceptability and access of the COVID-19 vaccine.

Materials and methods

We conducted a qualitative interview study with twenty guideline interviews with adult people currently experiencing homelessness in Berlin, Germany (August 2021 - April 2022). Participants were approached in a purposive sampling strategy. The interviews were analyzed with qualitative content analysis according to Mayring.

Results

Acceptance and attitude toward the COVID-19 vaccine is influenced by confidence in the vaccine as well as in the political and healthcare system, the individual COVID-19 risk perception and sense of collective responsibility. Overall, the acceptance of the vaccine was high among our participants. Facilities offering low threshold COVID-19 vaccines for people experiencing homelessness were perceived as helpful. Language barriers and the need for identity documents were major barriers to access the COVID 19 vaccine.

Discussion

People experiencing homelessness are a marginalized and vulnerable group often underrepresented in the public and scientific discourse. During the COVID-19 pandemic, preventive public health measures, including the COVID-19 vaccine, failed to consider specific needs of people experiencing homelessness. Multidimensional strategy to enhance inclusive healthcare are needed to improve access and to reduce discrimination and stigmatization.

Achieving Calm: A Study on the Health Care Experiences of People With Lived Experience of Homelessness in Central Texas

The experiences of care of people with lived experience of homelessness are rarely embraced to change care delivery. We conducted qualitative group and one-on-one interviews utilizing experience group methodology with 27 people with lived experience of homelessness currently housed in one permanent housing community in central Texas. We analyzed data using an inductive thematic approach to identify shared obstacles and barriers to receiving health care. We then analyzed findings with the capability, comfort, and calm value framework to identify health outcomes that matter most to study participants. Poor access to care, discontinuities in care, distrust in providers, and confusing terminology were identified as the biggest barriers to health. The overwhelming majority of experiences reflected poor health outcomes of calm, the outcome of a health care experience that adds ease to one's life rather than logistical and administrative chaos. We propose three practical approaches to achieve calm for this population as follows: systems-level embracement of compassionate care, integration of relationship-based care navigation into all levels of care, and building efficient transportation into care design. We conclude that designing health care that works in the lives of people with lived experience of homelessness is critical to address the gaps in care that fuel the health disparity these individuals face compared to people without this lived experience.

Addressing health needs of the homeless in Delhi: Standardising on the issues of Street Medicine practice

Due to barriers in accessing and using healthcare services, a large proportion of the care homeless populations receive comes from informal providers. In Delhi, one such informal programme, called Street Medicine, provides healthcare outreach to homeless communities. Clinical practice guidelines are set to be developed for Street Medicine teams in India and form the object of this research. This study uses a social-ecological model to understand the barriers facing Street Medicine teams and the homeless as they attempt to address the latter's healthcare needs; coupling it with an analytical approach which situates these barriers as the issues within practice through which standardisation can take place. A qualitative inquiry, comprising three months of observations of Street Medicine outreach and interviews with over 30 key informants, was conducted between April and July 2018. The analysis identified novel barriers to addressing the needs of homeless individuals, which bely a deficit between the design of health and social care systems and the agency homeless individuals possess within this system to influence their health outcomes. These barriers - which include user-dependent technological inscriptions, collaborating with untargeted providers and the distinct health needs of homeless individuals - are the entry points for standardising, or opening up, Street Medicine practices .

Cycles of instability: Proximal and distal influences on residential instability among people with histories of homelessness in three Canadian cities

People with histories of homelessness often have difficulties obtaining and maintaining adequate housing. This qualitative study examined the residential transitions of people with histories of residential instability and homelessness to understand factors contributing to the instability they experience. Interviews were conducted with 64 participants about their housing transitions, in the final year of a 4-year, prospective cohort study in three Canadian cities (Ottawa, Toronto, and Vancouver). Findings showed that participants pointed to both distal and proximal factors as affecting residential transitions, including interpersonal conflict, safety concerns, substance use, poverty, pests, and health. Many reported disconnection from their housing and a lack of improvement from one housing situation to the next, demonstrating how even when housed, instability persisted. Our study highlights the complexity associated with participants' often unplanned and abrupt residential transitions. The complex and distal issues that affect housing transitions require structural changes, in addition to individual-based interventions focused on the proximal problems.

Chronic diseases and multi-morbidity in persons experiencing homelessness: results from a cross-sectional study conducted at three humanitarian clinics in Germany in 2020

BACKGROUND

Persons experiencing homelessness (PEH) suffer a high burden of chronic diseases and multi-morbidity, yet face significant barriers in accessing healthcare services. These health inequalities were further aggravated during the COVID-19 pandemic. While there is a lack of comprehensive health data on PEH, even less is known about populations experiencing housing exclusion, a hidden form of homelessness. This study examines and compares chronic diseases and multi-morbidity in PEH, persons experiencing housing exclusion, and persons with secure housing who lacked access to regular healthcare services in the wake of the COVID-19 pandemic in Germany.

METHODS

Study participants were adults who sought medical care at clinics of the humanitarian organisation "Ärzte der Welt" in Munich, Hamburg and Berlin in 2020. The patients were categorised into three housing groups according to the ETHOS classification of homelessness and housing exclusion. Socio-demographic characteristics, self-rated health, chronic diseases and multi-morbidity were described in each group. Logistic regression analysis was used to identify socio-demographic factors associated with higher odds of chronic diseases and multi-morbidity in each housing group.

RESULTS

Of the 695 study participants, 333 experienced homelessness, 292 experienced housing exclusion and 70 had secure housing. 92.3% of all patients had either no or limited health coverage, and 96.7% were below the poverty line. Males and EU/EEA citizens were highly represented among PEH (74.2% and 56.8% respectively). PEH had lower self-rated health (47.8%, p = 0.04), and a higher prevalence of psychiatric illness (20.9%, p = 0.04). In adjusted analyses, belonging to the age group 35-49 and ≥ 50 years were associated with greater odds of chronic disease (AOR = 2.33, 95% CI = 1.68-3.24; AOR = 3.57, 95% CI = 2.55-5.01, respectively) while being ≥ 50 years old was associated with multi-morbidity (AOR = 2.01, 95% CI = 1.21, 3.33). Of the 18 participants tested for SARS-COV-2, 15 were PEH, 1 of whom tested positive.

CONCLUSIONS

Housing status was not an independent risk factor for chronic disease and multi-morbidity in our study population. However, PEH reported poorer self-rated and psychiatric health. Strategies to improve access to healthcare services amongst persons experiencing homelessness and housing exclusion are needed in Germany.

Photo elicitation to explore health and social exclusion with rooming house residents in Ottawa, Canada

Little is known about how rooming house residents perceive how housing influences their health, despite higher morbidity and premature death compared to other Canadians. The social exclusion framework of the Social Knowledge Exchange Network (SEKN) conceptualized by Popay et al. (2008) was used to investigate how rooming houses are linked to health among ten rooming house residents from six rooming houses in Ottawa, Ontario, Canada. Study activities included taking photos to show how living in a rooming house affects health, a community walk-about with the principal investigator, a focus group, and individual interviews. Thematic analysis revealed two broad themes: Housing is Health Care, and Just Managing Today. Findings suggest that structural inequalities and siloed care contribute to the health of rooming house residents, including the balance between poverty and desire to maintain housing, and how residents cope with this stress. If health care providers want to help alleviate the disparities in rooming house residents' health, they need to broaden the lens through which health is conceptualized.

Health Care Needs of Young Adults Who Have Experienced Homelessness

INTRODUCTION

Young adults experiencing homelessness have poorer overall health compared with the general population. However, not much is known about how health care needs may change in the transition from homelessness to supportive housing. This study utilizes the Gelberg-Andersen Behavioral Model for Vulnerable Populations to examine unmet health care needs among young adults currently experiencing homelessness and formerly homeless young adults living in supportive housing.

METHODS

This study includes data from 192 young adults who were either residing in a supportive housing program (n=103) or were "unhoused" (eg, residing on the street, staying in emergency shelters; n=89) in Los Angeles, CA, between 2017 and 2019. Hierarchical modeling examined unmet health care needs and factors that may enable those needs to be met, controlling for predisposing and other need factors.

RESULTS

Controlling for predisposing and other need characteristics, this study identified increased enabling factors among those residing in supportive housing, the most widely applied intervention for homelessness. Participants who resided in supportive housing were more likely to report at least 1 type of unmet need than youth who did not have access to housing. Additional findings regarding the association of enabling factors and unmet need yield mixed results based on the type of unmet need.

DISCUSSION

The acknowledgment of unmet needs may, in fact, be a byproduct of shifting priorities, which often occurs in the transition from homelessness to housing. Understanding the unmet need and health implications of this transition has relevance for practice as we work to better support formerly homeless young adults in meeting the needs that they identify.

Homelessness and Vulnerably-Housed Defined: A Synthesis of the Literature

There is no single accepted definition used in policy or research for the concepts of homelessness and vulnerably housed. Neuman's systems model (NSM) was the framework for this mixed-studies review, with the client system defined as these social issues and categorized as environmental stressors. Eighteen unique definitions of the concepts were identified in 30 studies. Extrapersonal stressors included housing history, interpersonal stressors included dependence on others for housing, and intrapersonal stressors included self-identification. Each level of stressor should be considered when defining these populations for inclusion in future research. Proposed definitions were formulated from the analysis of the results.

Housing and health in vulnerable social groups: an overview and bibliometric analysis

Previous studies have confirmed that poor living conditions can lead to a wide range of health problems. However, in the context of the COVID-19 pandemic, vulnerable groups in unstable housing are more susceptible to disease. This study aims to systematically examine the housing and health problems of vulnerable groups using a bibliometric approach to explore how housing causes health problems, types of health illnesses, and coping strategies. It is found that the poor housing mechanism, persistent inequalities, and poor housing environments have a significant impact on the health of vulnerable groups. Therefore, the government must make concerted efforts across all sectors to ensure that the housing and health care needs of vulnerable groups are improved, and that housing security standards and related policies are improved; targeted safety plans are formulated with community as the carrier, taking into account the characteristics of vulnerable groups; and new information technology is widely used to provide medical convenience for vulnerable groups. It is hoped that the research in this paper can arouse social attention to the health of vulnerable groups and improve their health from the perspective of housing, so as to point out the direction for solving the housing health problems of vulnerable groups in the future.

A first voice perspective of people experiencing homelessness on preferences for the end-of-life and end-of-life care during the COVID-19 pandemic

Objective

People experiencing homelessness often encounter progressive illness(es) earlier and are at increased risk of mortality compared to the housed population. There are limited resources available to serve this population at the end-of-life (EOL). The purpose of this study was to gain insight into preferences for the EOL and end-of-life care for people experiencing homelessness. Utilizing an interpretive phenomenology methodology and the theoretical lens of critical social theory, we present results from 3 participants interviewed from August to October 2020, with current or previous experience of homelessness and a diagnosis of advanced disease/progressive life-threatening illness.

Results

A key finding focused on the existential struggle experienced by the participants in that they did not care if they lived or died. The participants described dying alone as a bad or undignified way to die and instead valued an EOL experience that was without suffering, surrounded by those who love them, and in a familiar place, wherever that may be. This study serves to highlight the need for improvements to meet the health care and social justice needs of people experiencing homelessness by ensuring equitable, humanistic health and end-of-life care, particularly during the context of the COVID-19 pandemic.

A codevelopment process to advance methods for the use of patient-reported outcome measures and patient-reported experience measures with people who are homeless and experience chronic illness

Introduction

People who experience social disadvantage including homelessness suffer from numerous ill health effects when compared to the general public. Use of patient‐reported outcome measures (PROMs) and patient‐reported experience measures (PREMs) enables collection of information from the point of view of the person receiving care. Involvement in research and health care decision‐making, a process that can be facilitated by the use of PROMs and PREMs, is one way to promote equity in care.

Methods

This article reports on a codevelopment and consultation study investigating the use of PROMs and PREMs with people who experience homelessness and chronic illness. Data were analysed according to interpretative phenomenological analysis.

Results

Committee members with lived experience identified three themes for the role of PROMs and PREMs in health care measurement: trust and relationship‐building; health and quality of life; and equity, alongside specific recommendations for the design and administration of PROMs and PREMs. The codevelopment process is reported to demonstrate the meaningful investment in time, infrastructure and relationship‐building required for successful partnership between researchers and people with lived experience of homelessness.

Conclusion

PROMs and PREMs can be meaningful measurement tools for people who experience social disadvantage, but can be alienating or reproduce inequity if they fail to capture complexity or rely on hidden assumptions of key concepts.

Patient or Public Contribution

This study was conducted in active partnership between researchers and people with experience of homelessness and chronic illness, including priority setting for study design, data construction, analysis and coauthorship on this article.

The prevalence and causes of visual impairment among the male homeless population of Montreal, Canada

CLINICAL RELEVANCE

Homeless populations have lower health indicators, including in eye care. Few data exist on the levels and causes of visual impairment in Canadian homeless populations, and none in Montreal.

BACKGROUND

This study aims to characterise the causes and levels of visual impairment, as well as eye care services utilisation among the Montreal homeless.

METHODS

Using random sampling, five homeless shelters were selected. In each shelter, 20 participants were randomly selected. After obtaining informed consent, participants completed an ocular examination, which included: presenting visual acuity (pinhole as needed), intraocular pressure, confrontation visual field, dilated fundus examination, post-dilation autorefraction and questionnaire on social determinants of health.

RESULTS

A total of 95 participants were examined, of which 97.9% were male. The median age was 49 years old (interquartile range 38-56.5). The age-adjusted prevalence of visual impairment (presenting visual acuity <6/12) was 23.6% (95% CI 15.1-32.9) compared to 6.0% in the Canadian population (Z = 77.9, p < 0.0001). With pinhole correction, the prevalence of visual impairment dropped to 5.8% (95% CI 1.7-11.8). Prevalence was 8.2% (95% CI 3.7-15.9) for cataracts, 11.4% (95% CI 5.9-19.7) for glaucoma or suspects and 4.7% (95% CI 1.7-11.9) for diabetic retinopathy. Lastly, 18.9% of participants had an ocular examination within the last year compared to 41.4% in Canada (Z = -4.5, p < 0.0001) and 13.7% had never had a comprehensive eye examination.

CONCLUSIONS

This sample population shows a prevalence of visual impairment which is four times that of the general Canadian population, with highly prevalent uncorrected refractive error, while accessing primary eye care twice less often.

Protocol for a scoping review on rehabilitation among individuals who experience homelessness and traumatic brain injury

INTRODUCTION

Rehabilitation is key to improving outcomes and quality of life after traumatic brain injury (TBI). However, individuals experiencing homelessness are rarely represented in research that informs evidence-based rehabilitation guidelines even though TBI is disproportionately prevalent among this population. This protocol is for a scoping review to explore the extent to which rehabilitation, including the types of rehabilitation interventions, is available to, or used by, individuals who experience homelessness and TBI to inform (1) opportunities to integrate rehabilitation for individuals experiencing homelessness and TBI, (2) considerations for existing clinical and practice guidelines for rehabilitation and (3) recommendations for future research.

METHODS AND ANALYSIS

The scoping review will be guided by six stages described in scoping review methodology frameworks. Electronic databases (MEDLINE, Embase and Embase Classic, Cochrane CENTRAL Register of Clinical Trials, CINAHL, APA PsycINFO, Applied Social Sciences Index and Abstracts, and Nursing and Allied Health), reference list of included articles and scoping or systematic reviews identified from the search and grey literature, defined as reports from relevant brain injury, housing and rehabilitation organisations, will be searched. Two reviewers will independently screen all articles based on predetermined inclusion and exclusion criteria. A descriptive numerical summary of data items will be provided and qualitative content analytic techniques will be used to identify and report common themes. Preliminary findings will be shared with stakeholders to seek feedback on the implications of the results.

ETHICS AND DISSEMINATION

Ethics review will not be required, as only publicly available data will be analysed. Findings from the scoping review will be published in a peer-reviewed journal and presented at scientific meetings and to stakeholders, defined as service providers in the housing and TBI sectors; health professionals who provide care for individuals with TBI and/or homelessness; health administrators, decision-makers and policy-makers; researchers; and caregivers or family members of individuals with lived experience of TBI and homelessness.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Towards Equitable Health Care Access: Community Participatory Research Exploring Unmet Health Care Needs of Homeless Individuals

Community and health services often overlook health care needs of persons experiencing homelessness, which leads to deterioration in health and increased utilization of emergency services. Since homeless people are underrepresented in health service research, little is known about their unmet health care needs, particularly in smaller cities where resources are limited. This community-based participatory research explored the experiences of small-city homeless service users (HSUs) with unmet health care needs and community service providers (CSPs) who work with them to determine barriers to health care access affecting them. Structured interviews were conducted with 65 HSUs and 15 CSPs in interior British Columbia, Canada. These interviews were audio-recorded, and the retrieved data were analyzed thematically. The three themes uncovered included: a lack of access to health care and risk of stigma, a lack of trust and fear of discrimination, and a need for community navigation and social support. The findings indicate that HSUs do not receive equitable care and face challenges in accessing appropriate and timely foot care, which contributes to increased foot-related emergency visits, loss of trust in the health care system, and disabilities due to worsening foot conditions. Various social determinants of health also impact HSUs, such as low socioeconomic status, lack of housing, decreased social support, unhealthy behaviors, and inequitable access to health services. By collaborating with HSUs, community and health services need to develop innovative outreach programs that provide better community resources as the first step toward equitable access to health care.

Factors Associated with Readmission Among General Internal Medicine Patients Experiencing Homelessness

BACKGROUND

People who are homeless have a higher burden of illness and higher rates of hospital admission and readmission compared to the general population. Identifying the factors associated with hospital readmission could help healthcare providers and policymakers improve post-discharge care for homeless patients.

OBJECTIVE

To identify factors associated with hospital readmission within 90 days of discharge from a general internal medicine unit among patients experiencing homelessness.

DESIGN

This prospective observational study was conducted at an urban academic teaching hospital in Toronto, Canada. Interviewer-administered questionnaires and chart reviews were completed to assess medical, social, processes of care, and hospitalization data. Multivariable logistic regression with backward selection was used to identify factors associated with a subsequent readmission and estimate odds ratios and 95% confidence intervals.

PARTICIPANTS

Adults (N = 129) who were admitted to the general internal medicine service between November 2017 and November 2018 and who were homeless at the time of admission.

MAIN MEASURES

Unplanned all-cause readmission to the study hospital within 90 days of discharge.

KEY RESULTS

Thirty-five of 129 participants (27.1%) were readmitted within 90 days of discharge. Factors associated with lower odds of readmission included having an active case manager (adjusted odds ratios [aOR]: 0.31, 95% CI, 0.13-0.76), having informal support such as friends and family (aOR: 0.25, 95% CI, 0.08-0.78), and sending a copy of the patient's discharge plan to a primary care physician who had cared for the patient within the last year (aOR: 0.44, 95% CI, 0.17-1.16). A higher number of medications prescribed at discharge was associated with higher odds of readmission (aOR: 1.12, 95% CI, 1.02-1.23).

CONCLUSION

Interventions to reduce hospital readmission for people who are homeless should evaluate tailored discharge planning and dedicated resources to support implementation of these plans in the community.

Contexts and mechanisms that promote access to healthcare for populations experiencing homelessness: a realist review

Objective

The objective of this study was to identify and understand the health system contexts and mechanisms that allow for homeless populations to access appropriate healthcare when needed.

Design

A realist review.

Data sources

Ovid MEDLINE, embase.com, CINAHL, ASSIA and grey literature until April 2019.

Eligibility criteria for selecting studies

The purpose of the review was to identify health system patterns which enable access to healthcare for people who experience homelessness. Peer-reviewed articles were identified through a systematic search, grey literature search, citation tracking and expert recommendations. Studies meeting the inclusion criteria were assessed for rigour and relevance and coded to identify data relating to contexts, mechanisms and/or outcomes.

Analysis

Inductive and deductive coding was used to generate context–mechanism–outcome configurations, which were refined and then used to build several iterations of the overarching programme theory.

Results

Systematic searching identified 330 review articles, of which 24 were included. An additional 11 grey literature and primary sources were identified through citation tracking and expert recommendation. Additional purposive searching of grey literature yielded 50 records, of which 12 were included, for a total of 47 included sources. The analysis found that healthcare access for populations experiencing homelessness is improved when services are coordinated and delivered in a way that is organised around the person with a high degree of flexibility and a culture that rejects stigma, generating trusting relationships between patients and staff/practitioners. Health systems should provide long-term, dependable funding for services to ensure sustainability and staff retention.

Conclusions

With homelessness on the rise internationally, healthcare systems should focus on high-level factors such as funding stability, building inclusive cultures and setting goals which encourage and support staff to provide flexible, timely and connected services to improve access.

The effect of a Housing First intervention on primary care retention among homeless individuals with mental illness

Background

Primary care retention, defined as ongoing periodic contact with a consistent primary care provider, is beneficial for people with serious chronic illnesses. This study examined the effect of a Housing First intervention on primary care retention among homeless individuals with mental illness.

Methods

Two hundred individuals enrolled in the Toronto site of the At Home Project and randomized to Housing First or Treatment As Usual were studied. Medical records were reviewed to determine if participants were retained in primary care, defined as having at least one visit with the same primary care provider in each of two consecutive six-month periods during the 12 month period preceding and following randomization.

Results

Medical records were obtained for 47 individuals randomized to Housing First and 40 individuals randomized to Treatment As Usual. During the one year period following randomization, the proportion of Housing First and Treatment As Usual participants retained in primary care was not significantly different (38.3% vs. 47.5%, p = 0.39). The change in primary care retention rates from the year preceding randomization to the year following randomization was +10.6% in the Housing First group and -5.0% in the Treatment As Usual group.

Conclusion

Among homeless individuals with mental illness, Housing First did not significantly affect primary care retention over the follow-up period. These findings suggest Housing First interventions may need to place greater emphasis on connecting clients with primary care providers.

The use of eHealth interventions among persons experiencing homelessness: A systematic review

Objective

eHealth interventions are being developed to meet the needs of diverse populations. Despite these advancements, little is known about how these interventions are used to improve the health of persons experiencing homelessness. The aim of this systematic review was to examine the feasibility, effectiveness, and experience of eHealth interventions for the homeless population.

Methods

Following PRISMA guidelines, a systematic search of PsycINFO, PubMed, Web of Science, and Google Scholar was conducted along with forward and backward citation searching to identify relevant articles.

Results

Eight articles met eligibility criteria. All articles were pilot or feasibility studies that used modalities, including short message service, mobile apps, computers, email, and websites, to deliver the interventions. The accessibility, flexibility, and convenience of the interventions were valued by participants. However, phone retention, limited adaptability, a high level of human involvement, and preference for in-person communication may pose future implementation challenges.

Conclusions

eHealth interventions are promising digital tools that have the potential to improve access to care and service delivery. eHealth interventions are feasible and usable for persons experiencing homelessness. These interventions may have health benefits by augmenting existing services and if implementation challenges are addressed. Further evaluation of the effectiveness of eHealth interventions is needed before widespread implementation. Those with lived experience should also be engaged in developing and evaluating these interventions.

Making healthcare accessible for single adults with complex needs experiencing long-term homelessness: A realist evaluation protocol

Background: Over the last several years, homelessness has increased in Ireland and across Europe. Rates have recently declined since the coronavirus disease 2019 (COVID-19) pandemic, but it is unclear whether emergency housing measures will remain in place permanently. Populations experiencing long-term homelessness face a higher burden of multi-morbidity at an earlier age than housed populations and have poorer health outcomes. However, this population also has more difficulty accessing appropriate health services. A realist review by the authors found that important health system contexts which impact access are resourcing, training, funding cycles, health system fragmentation, health system goals, how care is organised, culture, leadership and flexibility of care delivery. Using a realist evaluation approach, this research will explore and refine key system-level factors, highlighted in our realist review, in a local health care system. Aim: The aim of this study is to understand how funding procedures and health system performance management impact service settings, staff, providers and their ability to make services accessible to populations experiencing homelessness. Methods: A realist evaluation will be undertaken to explain how funding and health system performance management impact healthcare accessibility for populations experiencing homelessness. Data will be collected using qualitative and realist interview techniques and focus group methodology. Secondary data such as policy documents and budgets will utilised. The analysis will follow Pawson and Tilley's iterative phases starting with building an Initial programme theory, then data collection, data analysis, synthesis and finally building a refined programme theory. Conclusion: Building on a realist review conducted by the same research team, this study will further test and refine findings that explain how health system factors impact healthcare accessibility for populations experiencing homelessness. The study has the potential to inform policy makers, health planners and managers of contextual factors that can be modified to increase healthcare accessibility.

Prevalence and burden of obstructive lung disease in the urban poor population of Ottawa, Canada: a community-based mixed-method, observational study

BACKGROUND

Globally the burden of Obstructive Lung Diseases (OLD) is growing, however its effect on urban poor populations with the high prevalence of tobacco dependence is virtually unknown. The purpose of this project is to estimate the prevalence and burden of OLD in the urban, low-income populations of Ottawa, Canada.

METHODS

The study presented in this paper was part of the PROMPT (Management and Point-of-Care for Tobacco Dependence) project; a prospective cohort study in a community-based setting (n = 80) with meaningful Patient Engagement from design to dissemination. Spirometry data, standardized questionnaires and semi-structured interviews from PROMPT were interpreted to understand the lung function, disease burden and social determinants (respectively) in this population.

RESULTS

The prevalence of OLD among those who completed spirometry (N = 64) was 45-59%. Generic and disease-specific quality of life was generally poor in all PROMPT participants, even those without OLD, highlighting the higher disease burden this vulnerable population faces. Quality of life was impacted by two major themes, including i) socioeconomic status and stress and ii) social networks and related experiences of trauma.

CONCLUSION

The prevalence and disease burden of OLD is significantly higher in Ottawa's urban poor population than what is observed in the general Canadian population who smoke, suggesting an etiological role of the social determinants of health. This urges the need for comprehensive care programs addressing up-stream factors leading to OLDs, including poor access and utilization of preventive healthcare addressing the social determinants of health.

Correlates of Depressive Symptoms among Middle-Aged and Older Homeless Adults Using the 9-Item Patient Health Questionnaire

This study investigates the screening for depressive symptoms among middle-aged and older homeless adults based on Patient Health Questionnaire-9 (PHQ-9) and examines the possible factors associated with their major depressive symptoms. A cross-sectional survey was employed, and research subjects included 129 homeless people aged 45 years old and over in Taipei Wanhua District and Taipei Main Station. We used a structured questionnaire and face-to-face interview conducted by three social workers to collect data in the analyses. The content of the questionnaire included an informed consent form, demographic characteristics, enabling and need factors of healthcare, and PHQ-9 of homeless people. Results revealed that 15.5% respondents were free of depressive symptoms, 16.3% had mild level (score 5–9), 31.8% had moderate level (score 10–14), 26.4% had moderately severe level (score 15–19), and 10.1% had severe level of depressive symptoms (score 20–27). Adopting a PHQ-9 score 10 as a cut-off point for major depressive symptoms, 68.3% of middle-aged and older homeless adults were the cases needing to be referred to healthcare settings for further recheck in the near future. A multiple regression analysis found gender, age, and usage of psychiatric outpatient care were associated with major depressive symptom occurrence. The female participants were less likely to have major depressive symptoms than the male participants (OR = 0.29, 95% CI = 0.09–0.96). The elderly participants were more likely to have major depressive symptoms than the aged 45–54 years (OR = 5.29, 95% CI = 1.44–19.41). Those participants who have ever used psychiatric outpatient care were significantly more correlated with the occurrence of major depressive symptoms than their counterparts (OR = 3.65, 95% CI = 1.46–9.09). The present study suggests that in the future health policy should eliminate the risk factors of depressive symptoms and improve mental healthcare access, to improve the health and wellbeing of the homeless population.

Supporting Primary Care Access and Use among Homeless Persons

With the implementation of the Affordable Care Act (ACA), many homeless persons who previously lacked health insurance gained medical coverage. This paper describes the experiences of homeless persons in accessing and using primary care services, post-implementation of the ACA. Twenty-six semi-structured interviews were completed with homeless persons and primary care providers/staff. Via thematic analysis, themes were identified, categorized by: factors which influence primary care access and use patterns, and strategies to promote consistent primary care use. Maintaining insurance and leveraging systems-based strategies to support primary care access and use may address health disparities and promote health equity.

Addressing the Poverty Barrier in Collaborative Care for Adults Experiencing Homelessness: A Case-Based Report

The Collaborative Care (CC) model of integrated care is an evidence-based, systematic approach in which primary care and behavioral health teams work together to deliver effective treatment for depression and other common mental illnesses in primary care settings. Because people experiencing homelessness have high rates of chronic medical conditions, mental illness and substance use disorders, interventions that integrate the physical, mental and social determinants of health have been shown to be effective to provide healthcare for this population in primary care outpatient settings. In this article we describe the implementation of a collaborative care program to treat depression in a population of adults experiencing homelessness and receiving primary care in a Federally Qualified Health Center (FQHC) located in Downtown Miami, Florida. We present three case studies that highlight key concepts, potential benefits and limitations in using this model to treat patients experiencing depression and homelessness in urban areas.

Homeless people's social representations about self-care

OBJECTIVES

To capture and analyze the structure of homeless people's social representations about self-care.

METHODS

Research based on the theory of social representations, with 122 people in street situation. A semistructured questionnaire and free evocation technique were applied with the inducing words "caring for myself is". The evocations were processed by the software Evoc and Iramuteq, allowing to identify central and peripheral elements and the connection between them.

RESULTS

For the group studied, "feeding oneself, personal hygiene, protecting oneself and visiting the doctor" are actions and attitudes that represent caring for themselves. In the streets, "feeding oneself" is an essential action for living/surviving that underpins the others.

FINAL CONSIDERATIONS

Despite behaviors based on the biomedical model, self-care was represented by extended actions to meet basic human needs. This study offers elements of reflection to rethink care practices developed by health professionals.

Violence and Emergency Department Use among Community-Recruited Women Who Experience Homelessness and Housing Instability

Women who experience housing instability are at high risk for violence and have disproportionately high rates of emergency department (ED) use. However, little has been done to characterize the violence they experience, or to understand how it may be related to ED use. We recruited homeless and unstably housed women from San Francisco shelters, free meal programs, and single room occupancy (SRO) hotels. We used generalized estimating equations to examine associations between violence and any ED use (i.e., an ED visit for any stated reason) every 6 months for 3 years. Among 300 participants, 44% were African-American, and the mean age was 48 years. The prevalence of violence experienced in the prior 6 months included psychological violence (87%), physical violence without a weapon (48%), physical violence with a weapon (18%), and sexual violence (18%). While most participants (85%) who experienced physical violence with a weapon or sexual violence in the prior 6 months had not visited an ED, these were the only two violence types significantly associated with ED use when all violence types were included in the same model (ORphysical/weapon = 1.83, 95% CI 1.02-3.28; ORsexual = 2.15, 95% CI 1.30-3.53). Only violence perpetrated by someone who was not a primary intimate partner was significantly associated with ED use when violence was categorized by perpetrator. The need to reduce violence in this population is urgent. In the context of health care delivery, policies to facilitate trauma-informed ED care and strategies that increase access to non-ED care, such as street-based medicine, could have substantial impact on the health of women who experience homelessness and housing instability.

Understanding unmet health-care need among older Ghanaians: a gendered analysis

Health insurance schemes are important for bridging gaps in health-care needs between the rich and poor, especially in contexts where poverty is higher among seniors (persons aged 65 years and above). In this study we examined (a) gender-based predictors of unmet health-care need among seniors and (b) whether access was influenced by wealth status (measured by income quintiles). Gender-specific negative log–log regression models were fitted to data from the Study on Global Ageing and Health to examine associations between unmet health-care need and health insurance status controlling for theoretically relevant covariates. Insurance status was an important determinant of men and women's unmet health-care need but the relationship was moderated by income quintile for women and not men. While occupation was important for men, religion, marital status and income quintile were significantly associated with women's unmet health-care need. Based on the observed gender differences, we recommend the implementation of programmes aimed at improving the economic situation of older people, particularly women.

"Now that you've got that coverage": Promoting use of a regular source of primary care among homeless persons

BACKGROUND

The growing number of homeless persons in the United States demonstrates greater morbidity and mortality than the population as a whole. Homeless persons are often without a regular source of primary care. Homeless persons use emergency departments and are hospitalized at higher rates than nonhomeless persons. In 2010, the enactment of the Affordable Care Act expanded access to primary care services. Nurse practitioners were at the forefront of its subsequent implementation.

PURPOSE

The purpose of this qualitative study was to explore the factors that influence establishing and maintaining a regular source of primary care among homeless persons.

METHODOLOGICAL ORIENTATION

In 2017, semistructured interviews were conducted in a federally qualified health center that serves predominately homeless persons.

SAMPLE

A purposive convenience sample included adult health center users (N = 20). The majority of participants were insured (90%), African American (70%), and male (65%).

CONCLUSIONS

Thematic analysis revealed five facilitators: sense of community, mutual patient-provider respect, financial assurance, integrated health services, and patient care teams. To establish and maintain use of a regular primary care source, homeless persons desire to experience a sense of community, feel respected by their provider/staff, and have certainty that costs will not exceed their capacity to pay. Integrated care models that leverage a multidisciplinary team approach support the use of a regular primary care source.

IMPLICATIONS FOR PRACTICE

Actualizing achievable strategies that promote the consistent use of a regular primary care source can reduce use of avoidable emergency and hospital-based services, thereby improving health outcomes among homeless persons.

Cardiovascular Disease and Homelessness

Cardiovascular disease (CVD) is a major cause of death among homeless adults, at rates that exceed those in nonhomeless individuals. A complex set of factors contributes to this disparity. In addition to a high prevalence of cigarette smoking and suboptimal control of traditional CVD risk factors such as hypertension and diabetes, a heavy burden of nontraditional psychosocial risk factors like chronic stress, depression, heavy alcohol use, and cocaine use may confer additional risk for adverse CVD outcomes beyond that predicted by conventional risk estimation methods. Poor health care access and logistical challenges to cardiac testing may lead to delays in presentation and diagnosis. The management of established CVD may be further challenged by barriers to medication adherence, communication, and timely follow-up. The authors present practical, patient-centered strategies for addressing these challenges, emphasizing the importance of multidisciplinary collaboration and partnership with homeless-tailored clinical programs to improve CVD outcomes in this population.

Prevalence and Risk Factors of Brain Infarcts and Associations With Cognitive Performance in Tenants of Marginal Housing

Background Homeless and vulnerably housed individuals are at increased risk for multimorbidity compared with the general population. We assessed prevalence of brain infarcts on neuroimaging and associations with vascular risk factors and cognitive performance in a prospective study of residents living in marginal housing. Methods and Results Two hundred twenty-eight participants underwent structured clinical interviews, targeted clinical, laboratory, and neuropsychological assessments, and magnetic resonance imaging with T1, T2-fluid-attenuated inversion recovery and susceptibility-weighted images. Subjects underwent cognitive testing to assess premorbid IQ , verbal learning and memory, inhibition, sustained attention, mental flexibility, and decision making. In this sample (mean age 44.0 years [ SD 9.4], 77% male), prevalence of conventional vascular risk factors was lower than in the general population apart from tobacco use (94%). Ten-year Framingham risk for any cardiovascular event was 11.4%±9.2%. Brain infarcts were present in 25/228 (11%). All were ischemic (40% cortical, 56% lacunar, 4% both). Participants with infarcts were older than those without (48.9±9.4 versus 43.4±9.2, P=0.006). In a multivariable regression analysis, only age remained a significant predictor of brain infarcts (odds ratio 1.08, 95% CI 1.02-1.14, P=0.004). After controlling for age and education, the presence of infarct was a significant predictor of impaired decision making on the Iowa Gambling Task of decision making (β -28.2, 95% CI -42.7 to -14.1, P<0.001). Conclusions Prevalence of infarcts on neuroimaging in this disadvantaged, community-dwelling cohort was much higher than expected for age and was associated with impaired decision making. Further research is needed to identify individuals at highest risk who may benefit from targeted preventative strategies.

Experience of healthcare among the homeless and vulnerably housed a qualitative study: opportunities for equity-oriented health care

BACKGROUND

People experiencing homelessness are often marginalized and are known to face barriers to accessing acceptable and respectful healthcare services. This study examines the experience of accessing hospital-based services of persons experiencing homelessness or vulnerable housing in southeastern Ontario and considers the potential of Equity-Oriented Health Care (EOHC) as an approach to improving care.

METHODS

Focus groups and in-depth interviews with people with lived experience of homelessness (n=31), as well as in-depth interviews of health and social service provider key informants (n=10) were combined with qualitative data from a survey of health and social service providers (n=136). Interview transcripts and written survey responses were analyzed using directed content analysis to examine experiences of people with lived experience of homelessness within the healthcare system.

RESULTS

Healthcare services were experienced as stigmatizing and shaming particularly for patients with concurrent substance use. These negative experiences could lead to avoidance or abandonment of care. Despite supposed universality, participants felt that the healthcare system was not accountable to them or to other equity-seeking populations. Participants identified a system that was inflexible, designed for a perceived middle-class population, and that failed to take into account the needs and realities of equity-seeking groups. Finally, participants did identify positive healthcare interactions, highlighting the importance of care delivered with dignity, trust, and compassion.

CONCLUSIONS

The experiences of healthcare services among the homeless and vulnerably housed do not meet the standards of universally accessible patient-centered care. EOHC could provide a framework for changes to the healthcare system, creating a system that is more trauma-informed, equity-enhancing, and accessible to people experiencing homelessness, thus limiting identified barriers and negative experiences of care.

Cognitive profiles and associated structural brain networks in a multimorbid sample of marginalized adults

Introduction

Cognition is impaired in homeless and vulnerably housed persons. Within this heterogeneous and multimorbid group, distinct profiles of cognitive dysfunction are evident. However, little is known about the underlying neurobiological substrates. Imaging structural covariance networks provides a novel investigative strategy to characterizing relationships between brain structure and function within these different cognitive subgroups.

Method

Participants were 208 homeless and vulnerably housed persons. Cluster analysis was used to group individuals on the basis of similarities in cognitive functioning in the areas of attention, memory, and executive functioning. The principles of graph theory were applied to construct two brain networks for each cognitive group, using measures of cortical thickness and gyrification. Global and regional network properties were compared across networks for each of the three cognitive clusters.

Results

Three cognitive groups were defined by: higher cognitive functioning across domains (Cluster 1); lower cognitive functioning with a decision-making strength (Cluster 3); and an intermediate group with a relative executive functioning weakness (Cluster 2). Between-group differences were observed for cortical thickness, but not gyrification networks. The lower functioning cognitive group exhibited higher segregation and reduced integration, higher centrality in select nodes, and less spatially compact modules compared with the two other groups.

Conclusions

The cortical thickness network differences of Cluster 3 suggest that major disruptions in structural connectivity underlie cognitive dysfunction in a subgroup of people who have a high multimorbid illness burden and who are vulnerably housed or homeless. The origins, and possible plasticity of these structure-function relationships identified with network analysis warrant further study.

Understanding the surgical care needs and use of outpatient surgical care services among homeless patients at the Ottawa Hospital

Background

The use of outpatient health care services by homeless people is low compared to their high level of need; however, it is unclear whether this applies to surgical care. We sought to describe surgical care access among homeless patients in a Canadian tertiary care setting.

Methods

We reviewed the medical records of adult (age > 18 yr) patients with no fixed address or a shelter address who presented to The Ottawa Hospital Emergency Department from Jan. 1, 2013, to Dec. 31, 2014, and required surgical referral. We analyzed the data using descriptive statistics.

Results

A surgical referral was initiated in 129 emergency department visits for 97 patients (77 men [79%], mean age 46.7 yr). Most patients lived in shelters (77 [79%]) and had provincial health insurance (82 [84%]), but only 35 (36%) had a primary care physician. The mean number visits for any reason was 7.9 (standard deviation 13.7) (range 1–106). The majority of surgical referrals (83 [64.3%]) were for traumatic injuries, and the most frequently consulted service (52 [40.3%]) was orthopedic surgery. Just under half (48 [49%]) of referred patients attended at least 1 outpatient appointment, and only a third (33 [34%]) completed full follow-up.

Conclusion

Homeless patients presenting to an emergency department and requiring surgical care were predominantly men living in shelters, most frequently seeking care for traumatic injuries. Current outpatient services may not meet the surgical care needs of these patients, as many do not access them. Alternative approaches to outpatient care must be considered, particularly among high-need services such as orthopedics, to support surgical care access among this population.

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

OBJECTIVE

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

METHOD

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

RESULTS

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

CONCLUSIONS

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

Costs Associated with Health Care Services Accessed through VA and in the Community through Medicare for Veterans Experiencing Homelessness

OBJECTIVE

To estimate health care utilization and costs incurred by homeless Veterans relative to nonhomeless Veterans and to examine the impact of a VA homelessness program on these outcomes.

DATA SOURCES/STUDY SETTING

Combined Department of Veterans Affairs (VA) administrative and Medicare claims data.

STUDY DESIGN

Observational study using longitudinal data from Veterans engaged with the VA system and enrolled in Medicare. Veterans with administrative evidence of homelessness at any point during 2006-2010 were matched on period of military service to Veterans with no evidence of homelessness.

PRINCIPAL FINDINGS

Experience of homelessness was associated with 1.37 (95 percent CI = 1.34-1.40) and 0.16 (95 percent CI = 0.14-0.17) more outpatient encounters per quarter in VA and non-VA settings, respectively, and 1.31 (95 percent CI = 1.30-1.32) and 0.49 (95 percent CI = 0.48-0.49) more inpatient days per quarter in VA and non-VA hospitals, respectively. These were associated with higher costs. Relative to stably housed Veterans less than 65 years of age, those enrolled in a VA homelessness program had 94.4 percent (95 percent CI = 90.7 percent-98.1 percent) more VA outpatient visits but 5.5 percent (95 percent CI = 3.0 percent-7.9 percent) fewer Medicare outpatient visits.

CONCLUSIONS

Homelessness was associated with an increase in VA and Medicare utilization and cost. A VA homelessness program decreased use of Medicare outpatient services.
