Housing status and accidental substance-related acute toxicity deaths in Canada, 2016-2017. / Recherche quantitative originale Statut résidentiel et décès accidentels attribuables à une intoxication aiguë liée à une substance au Canada, 2016-2017.

INTRODUCTION: There is a complex relationship between housing status and substance use, where substance use reduces housing opportunities and being unhoused increases reasons to use substances, and the associated risks and stigma. METHODS: In this descriptive analysis of people without housing who died of accidental substance-related acute toxicity in Canada, we used death investigation data from a national chart review study of substance-related acute toxicity deaths in 2016 and 2017 to compare sociodemographic factors, health histories, circumstances of death and substances contributing to death of people who were unhoused and people not identified as unhoused, using Pearson chi-square test. The demographic distribution of people who died of acute toxicity was compared with the 2016 Nationally Coordinated Point-In-Time Count of Homelessness in Canadian Communities and the 2016 Census. RESULTS: People without housing were substantially overrepresented among those who died of acute toxicity in 2016 and 2017 (8.9% versus <1% of the overall population). The acute toxicity event leading to death of people without housing occurred more often in an outdoor setting (24%); an opioid and/or stimulant was identified as contributing to their death more frequently (68%-82%; both contributed in 59% of their deaths); and they were more frequently discharged from an institution in the month before their death (7%). CONCLUSION: We identified several potential opportunities to reduce acute toxicity deaths among people who are unhoused, including during contacts with health care and other institutions, through harm reduction supports for opioid and stimulant use, and by creating safer environments for people without housing.

Formative Assessment and Cluster Membership of Homeless Persons' Emergency Department Visits.

Background Evidence is limited on whether homeless individuals who visit emergency departments (EDs) share similar clinical characteristics as individuals from private households who, upon examination, require emergency health services beyond preventative healthcare. While the literature is rich with studies on homeless persons in the ED, a comprehensive assessment of similarities and differences with other social groups is lacking. Consequently, there is a gap in knowledge as it pertains to the appropriate approaches that will further support the development of targeted healthcare and emergency health services for the homeless person. Aim The goal is to provide a framework for targeted interventions that hospitals can develop based on behavioral, health, and social characteristics and, in the process, better meet the healthcare needs of homeless patients. Methods Data were collected from the records of 85,350 patients in the National Hospital Ambulatory Medical Care Survey (NHAMCS) database who visited the ED between the years of 2013 and 2016; each patient was classified as having either a private residence, living in a nursing home, or homeless (n = 83,446, n = 1,459, and n = 925, respectively). Results Cluster analysis of the data confirmed that individuals with multiple comorbidities, as well as substance abuse or dependency, regardless of residence type, were more likely to have recurrent ED visits within 72 hours. Nominal regression analyses revealed that cluster membership generated from ED data could predict patient residence and suggest that substance abuse and depression can predict 72-hour ED visit recurrence. Conclusion Cluster analyses have the potential to reveal social health and group characteristics and can support targeted solutions respective to group individualities in the ED.

Transfer to community and prison mental health care from Ireland's main remand prison over three years: 2015-2017.

Background: The post-release period is associated with an increased risk of morbidity and mortality. Previous studies have identified deficits in pre-release planning for mentally ill people in prison, particularly in remand settings. Objectives: We aimed to determine the proportion of mentally ill people in Ireland's main remand prison who were referred for mental health follow up in community and prison settings, who achieved face to face contact with the receiving service. Method: This retrospective observational cohort study was based in Ireland's main male remand prison, Cloverhill. Participants included all those individuals on the caseload of the prison inreach mental health team who were referred for mental health follow up in community and prison settings at the time of discharge, prison transfer or release from custody over a three-year period, 2015 - 2017. Successful transfer of care (TOC) was defined as face-to-face contact with the receiving service, confirmed by written correspondence or by follow up telephone call. Clinical, demographic and offence related variables were recorded for all participants. Results: There were 911 discharges from the prison inreach mental health team within the three-year study period. Of these, 121 were admitted to hospital, 166 were transferred to other prison inreach mental health services and 237 were discharged to community based mental health follow up in psychiatric outpatient or primary care settings. One third (304/911) had an ICD-10 diagnosis of schizophreniform or bipolar disorder (F20-31) and 37.5% (161/911) were homeless. Over 90% (152/166) of those referred to mental health teams in other prisons achieved successful TOC, with a median of six days to first face-to face assessment. Overall, 59% (140/237) of those referred to community psychiatric outpatient or primary care services achieved TOC following referral on release from custody, with a median of nine days from release to assessment. Clinical and demographic variables did not differ between those achieving and not achieving successful TOC, other than having had input from the PICLS Housing Support Service. Conclusion: Successful transfer of care can be achieved in remand settings using a systematic approach with an emphasis on early and sustained interagency liaison and clear mapping of patient pathways. For incarcerated individuals experiencing homelessness and mental health disorders, provision of a housing support service was associated with increased likelihood of successful transfer of care to community mental health supports.

Role of homelessness and psychiatric disorders in suicide deaths among veterans: A four-way decomposition analysis.

Homelessness and suicide are top priorities in the U.S. Department of Veterans Affairs (VA). This study examined the various pathways involving homelessness, substance use, and mental health disorders in relation to suicide deaths among veterans in the VA healthcare system. A retrospective cohort study was conducted among 6,128,921 veterans-399,125 homeless and 5,729,796 non-homeless-followed-up between 2017 and 2021 using VA/Department of Defense linked databases. Multivariable Cox regression was applied for homelessness and psychiatric disorders as predictor of suicide deaths, sequentially controlling for demographic, clinical, substance use, and mental health characteristics. Four-way decomposition analysis was used to calculate proportions of suicide deaths mediated and/or moderated by homelessness, substance use, and mental health disorders. The relationship between homelessness and suicide-specific mortality risk was reduced from 40 % greater risk in unadjusted to 9 % greater risk in fully-adjusted models. Nearly 26 % of the total effect of homelessness on suicide-specific mortality risk was mediated by substance use disorders, whereas 49 % was mediated and 36 % was moderated by mental health disorders. In conclusion, excess suicide-specific mortality risk in homeless veterans is partly explained by substance use and mental health disorders, highlighting the importance of wrap-around health and social services for homeless veterans in mitigating suicide risk.

Policy, Design, and Critical Reflections on Behavioral Health Crisis Services for People Experiencing Homelessness.

People experiencing homelessness in crisis have unique structural vulnerabilities and social needs, most importantly lack of housing. Ideal crisis services for people experiencing homelessness must safeguard against criminalization and displacement during periods of crisis, prioritize equity, and provide housing interventions alongside mental health treatment at every stage in the crisis continuum. By outlining how to tailor crisis system financing and accountability, service component and capacity, and clinical best practices, the authors aim to provide hope and guidance for communities aiming to create an ideal crisis system for people experiencing homelessness.

Organizational and patient factors associated with positive primary care experiences for veterans with current or recent homelessness.

OBJECTIVE: To identify organizational service features associated with positive patient ratings of primary care within primary care clinics tailored to accommodate persons with ongoing and recent experiences of homelessness (PEH). DATA SOURCES AND STUDY SETTING: PEH receiving primary care in 29 United States Veterans Health Administration homeless-tailored clinics were surveyed about their primary care experience using the validated Primary Care Quality-Homeless (PCQ-H) survey. Characteristics of the clinics were assessed through surveys of clinic staff using a new organizational survey developed through literature review, site visits, statistical analysis, and consensus deliberation. STUDY DESIGN: Cross-sectional examination of patients' ratings of care based on surveys of patients, and of clinic characteristics, analyzed with Classification and Regression Tree (CART) analysis, a form of machine learning. DATA COLLECTION METHODS: Patient surveys (n = 3394) were obtained from a random sample of enrolled patients by both mail and telephone by an external survey contractor. Staff (n = 52 from 29 clinics) were interviewed by telephone. PRINCIPAL FINDINGS: This analysis identified service features that impact patient experience favorably, including aspects of patient-centeredness, team identity, strong external leadership support, and service that reach beyond traditional primary care clinic confines. Results varied according to the patient experience scale analyzed. Individual characteristics of PEH, such as degree of social support, general health, and unsheltered status, were also correlated with how they rate care. CONCLUSIONS: Organizational characteristics correlate with ratings of primary care from patients with recent and ongoing homelessness. Primary care programs serving homeless individuals can assure better care based on who they hire, how they foster team identity, what services they provide, and the strength of leadership support to protect a homeless-focused mission.

Comparative treatment of homeless persons with an infectious disease in the US emergency department setting: a retrospective approach.

BACKGROUND: Research has long documented the increased emergency department usage by persons who are homeless compared with their housed counterparts, as well as an increased prevalence of infectious diseases. However, there is a gap in knowledge regarding the comparative treatment that persons who are homeless receive. This study seeks to describe this potential difference in treatment, including diagnostic services tested, procedures performed and medications prescribed. METHODS: This study used a retrospective, cohort study design to analyse data from the 2007-2010 United States National Hospital Ambulatory Medical Care Survey database, specifically looking at the emergency department subset. Complex sample logistic regression analysis was used to compare variables, including diagnostic services, procedures and medication classes prescribed between homeless and private residence individuals seeking emergency department treatment for infectious diseases. Findings were then adjusted for potential confounding variables. RESULTS: Compared with private residence individuals, persons who are homeless and presenting with an infectious disease were more likely (adjusted OR: 10.99, CI 1.08 to 111.40, p<0.05) to receive sutures or staples and less likely (adjusted OR: 0.29, CI 0.10 to 0.87, p<0.05) to be provided medications when presenting with an infectious disease in US emergency departments. Significant differences were also detected in prescribing habits of multiple anti-infective medication classes. CONCLUSION: This study detected a significant difference in suturing/stapling and medication prescribing patterns for persons who are homeless with an infectious disease in US emergency departments. While some findings can likely be explained by the prevalence of specific infectious organisms in homeless populations, other findings would benefit from further research.

The beliefs and practices used to promote physical and mental health in youth who identify as lesbian, gay, bisexual, transgender, intersex, or queer plus (LGBTIQ+) experiencing housing insecurity: An integrative review.

PURPOSE: The purpose of this integrative review was to explore the beliefs and practices used to promote physical and mental health among youth ages 18-25 years, identifying as LGBTIQ+ experiencing housing insecurity. METHOD: The approach used strategies described by Whittemore and Knafl. Peer-reviewed, published research articles in English were identified using eight electronic databases. Eighteen research reports using qualitative, quantitative, and mixed methods were identified. Articles were evaluated for quality using the American Association of Critical Care Nurses Evidenced-Level Hierarchy evaluation tool. Data were analyzed and synthesized using Braun and Clarke's method. FINDINGS: Four themes related to the purpose were extracted: pervasive experiences of stigma and discrimination, constantly attuned to navigating risks, inconsistent engagement in health information and care, and inner strength developed through personal and community experiences. DISCUSSION: There are strong implications for future research, public health nursing practice, and health policy. Public health nurses should incorporate social determinants of health (addressing harmful social processes such as homophobia and racism) as well as a strength-based upstream approach in research, education, and health care practices. More research must also be done to assess engagement in physical and mental health information and care.

Traumatic Brain Injury and Its Risk Factors in a Homeless Population.

OBJECTIVE: To characterize the traumatic brain injury profile and its associated risk factors in homeless individuals in Santa Clara County, CA. DESIGN: Observational cohort study SETTING: : Two homeless shelter health clinics in Santa Clara County, CA PARTICIPANTS: Currently or recently homeless individuals seeking health care at two homeless shelter health clinics between August 2013 and May 2014. INTERVENTIONS: Not applicable MAIN OUTCOME MEASURES: Demographics, traumatic brain injury incidence and characteristics RESULTS: Findings indicate that TBI history in the homeless population is higher (79.7%) than the general population (12%). Almost half of the population (49.2%) reported that their TBI occurred before the age of 18. 68.2% of participants reported sustaining a TBI with loss of consciousness. TBI due to violence (60%) was lower in this cohort compared to other homeless cohorts but was the main cause of injury regardless of age. Alcoholism was a risk factor for having more TBIs. No differences in TBI profile were found between genders. CONCLUSION: Our findings underscore the need for more research on the lifetime risk factors associated with TBI to prevent and reduce the number of brain injuries in homeless populations.

What We (Don't) Know about the Infectious Disease Burden Among Youth Experiencing Homelessness in the United States and Canada.

Youth experiencing homelessness (YEH) and sexual and gender minority (SGM) YEH may be at increased risk for infectious diseases due to living arrangements, risk behaviors, and barriers to healthcare access that are dissimilar to those of housed youth and older adults experiencing homelessness. To better understand infectious diseases among YEH populations, we synthesized findings from 12 peer-reviewed articles published between 2012 to 2020 which enumerated YEH or SGM YEH infectious disease burden in locations across the U.S. or Canada. Pathogens presented in the studies were limited to sexually transmitted infections (STIs) and bloodborne infections (BBI). Only three studies enumerated infectious diseases among SGM YEH. There was a dearth of comparison data by housing status (ex., sheltered versus unsheltered youth), SGM identity, or other relevant counterfactual groups in the identified studies. We also introduce three publicly available, national-level surveillance datasets from the U.S. or Canada that quantify certain STIs, BBIs, and tuberculosis among YEH, which may be used for future disease burden assessments. Our review calls for more comprehensive YEH-centered research that includes multimodal data collection and timely disease surveillance to improve estimates of infectious diseases among this vulnerable population.

The global prevalence of mental health disorders among runaway and homeless youth: A meta-analysis.

A meta-analysis was performed to identify the pooled prevalence of mental health disorders (MHDs) among runaway and homeless youth (RHY). Relevant studies published between December 1, 1985, and October 1, 2023, were identified in the PubMed, Scopus, Web of Science, and Cochrane Library databases. A preliminary screening of 11,266 papers resulted in the inclusion of 101 studies. The pooled-prevalence estimates were obtained using a random-effects model. The findings showed varying lifetime prevalence rates of MHDs: 47% (conduct disorders and psychological distress), 43% (depression), 34% (major depressive disorders), 33% (post-traumatic stress disorder), 27% (personality disorders), 25% (attention-deficit/hyperactivity disorder), 23% (bipolar disorders), 22% (anxiety), 21% (oppositional defiant disorders), 15% (anorexia), 15% (adjustment disorders), 14% (dysthymia), 11% (schizophrenia), 9% (obsessive-compulsive disorders), and 8% (gambling disorder). The current prevalence rates were: 31% (depression), 23% (major depressive disorder), 23% (anxiety), 21% (post-traumatic stress disorder), 16% (attention-deficit/hyperactivity disorder), 15% (bipolar disorder), 13% (personality disorders), 13% (oppositional defiant disorders), 8% (schizophrenia), and 6% (obsessive-compulsive disorders). Regular screening and the implementation of evidence-based treatments and the promotion of integration and coordination between mental health services for adolescent minors and young adults with other service systems are recommended.

Drivers of Being Unhoused and the Prevalence of Health Conditions among Unhoused Individuals in Asheville, NC.

Background: During the COVID-19 pandemic, there was an increase in the number of unhoused individuals in Asheville, North Carolina resulting in more tent encampments.Understanding the physical, mental, and socially determined health characteristics associated with being unhoused can help guide stakeholders with policy development, healthcare program planning, and funding decisions to support unhoused individuals. Methods: In this study, we used an observational cross-section methodology. Using a convenience sample approach, we interviewed 101 participants who were receiving services from 2 emergency hotel shelters, a day center, and a resource center. Data were analyzed using descriptive statistics, and open-ended responses were collected and grouped to provide context. Results: Most participants were White (71%) and identified as male (76%). Over 60% reported having a high school education or advanced degree. Of the participants, 76% reported being unhoused for more than 6 months, and their last permanent housing was in Western North Carolina. Dental disease, chronic pain, and hypertension were common physical conditions. PTSD, depression, and anxiety were common mental health conditions. A lack of transportation was the most noted socially determined challenge. Marijuana, methamphetamine, and alcohol were the most often used substances, where methamphetamine was noted to be particularly problematic for the participants. Conclusion: Understanding the physical, mental, and social issues of the complex unhoused population can assist policymakers, healthcare providers, and other stakeholders in addressing challenges and testing improvement strategies.

Longitudinal relationships between early-life homelessness and school-aged asthma and wheezing.

BACKGROUND: Homelessness is a disruptive life event with profound impacts on children's health. It remains unclear, however, whether homelessness in early life has an enduring association with asthma and wheezing among school-aged children. OBJECTIVE: To test whether early-life homelessness is prospectively associated with asthma and wheezing during school-aged years. METHODS: We draw on data from 9242 children from the Avon Longitudinal Study of Parents and Children. Children were categorised as 'ever' or 'never' homeless based on maternal reports from the prenatal period through age 5 years. Children were assigned a binary indicator of asthma/wheezing based on maternal reports of asthma and wheezing at ages 6.8, 7.6 and 8.6 years. We used multilevel logistic regression models to test the association of interest in both bivariate analyses and models adjusted for a broad set of potential confounders. We conducted sensitivity analyses using generalised estimating equations and considering asthma and wheezing separately to test the robustness of the results. RESULTS: Between 12.1% and 14.3% of children had asthma or wheezing at ages 6.8, 7.6 and 8.6 years, and these conditions were more common among ever homeless participants. Ever-homeless children displayed higher odds of asthma or wheezing than never-homeless children (OR: 1.59, 95% CI 1.02 to 2.48) after adjustment for child, maternal and household risk factors. Sensitivity analyses yielded similar results. CONCLUSION: Early-life homelessness is prospectively associated with asthma and wheezing among school-aged children and should be prioritised by interventions promoting healthy child development.

Funding Health Care for People Experiencing Homelessness: An Examination of Federally Qualified Health Centers' Funding Streams and Homeless Patients Served (2014-2019).

It is estimated that three million people annually experience homelessness, with about a third of the homeless population being served by Federally Qualified Health Centers (FQHCs). Thus, FQHCs, dependent on government funding for financial viability, are vital to the infrastructure addressing the complex issues facing people experiencing homelessness. This study examines the relationship between various government funding streams and the number of homeless patients served by FQHCs. Data for this study come from three publicly available databases: the Uniform Data System (UDS), the IRS Core files, and the Area Resource File. Fixed-effects models employed examine changes across six years from 2014 to 2019. The results suggest that, on average, an additional homeless patient served increases the expenses of FQHCs more than other patients and that federal funding, specifically Health Care for the Homeless (HCH) funding, is a vital revenue source for FQHCs. We found that the number of homeless patients served is negatively associated with contemporaneous state and local funding but positively associated with substance use and anxiety disorders. Our findings have important implications for the effective management of FQHCs in the long term and for broader public policy supporting these vital elements of the social safety net.

Antecedents and Consequences of Violence in Homeless Shelters: Perspectives and Experiences of Service Users and Shelter Staff.

Violence is a critical issue in homeless shelters that affects service users and staff, yet there is limited evidence on how shelter-based violence occurs. The objective of this qualitative study was to investigate the antecedents and consequences of shelter-based violence from the perspectives of service users and staff. Purposive sampling was used to recruit individuals experiencing homelessness and shelter staff in a large metropolitan city in Ontario, Canada. Data from in-depth interviews with 56 individuals experiencing homelessness and 30 shelter staff were analyzed. Findings showed that shelter-based violence toward service users and staff was perceived to manifest in response to three interacting factors: (a) burden of homelessness and shelter living, (b) individual histories and marginalization, and (c) interpersonal conflict. These antecedents had a hierarchical structure in that each subsequent factor exacerbated the risk of previous ones and culminated with the most proximal factor for violence. There were three primary outcomes of shelter-based violence reported by service users and staff: (a) health and environmental harms, (b), procedural enforcement, and (c) avoidant behaviors. Avoidance was often a subsequent impact following health harms, as was procedural enforcement to a lesser extent. Overall, the study findings demonstrate that shelter-based violence is a complex and dynamic problem that is perceived to be the result of interacting structural, environmental, programmatic, interpersonal, and individual factors, with similar consequences for service users and staff. Implications for preventing violence through shelter design and service delivery are discussed.

Disparities in diabetes processes of care among people experiencing homelessness: An opportunity for intervention.

AIMS: To compare processes of diabetes care by homeless status. METHODS: A population-based propensity matched cohort study was conducted in Ontario, Canada. People with diabetes were identified in administrative healthcare data between April 2006 and March 2019. Those with a documented history of homelessness were matched to non-homeless controls. Data on processes of care measures included glucose monitoring tests, screening for microvascular complications, and physician follow-up. Differences in processes of care were compared by homeless status using proportions, risk ratios, and rate ratios. RESULTS: Of the 1,076,437 people with diabetes, 5219 matched pairs were identified. Homelessness was associated with fewer tests for glycated hemoglobin (RR = 0.63; 95 %CI: 0.60-0.67), LDL cholesterol (RR = 0.80; 95 %CI: 0.78-0.82), serum creatinine (RR = 0.94; 95 %CI: 0.92-0.97), urine protein quantification (RR = 0.62; 95 %CI: 0.59-0.66), and eye examinations (RR = 0.74; 95 %CI: 0.71-0.77). People with a history of homelessness were less likely to use primary care for diabetes management (RR = 0.62; 95 %CI: 0.59-0.66) or specialist care (RR = 0.87; 95 %CI: 0.83-0.91) compared to non-homeless controls. CONCLUSIONS: Disparities in diabetes care are evident for people with a history of homelessness and contribute to excess morbidity in this population. These data provide an impetus for investment in tailored interventions to improve healthcare equity and prevent long-term complications.

Identification of homelessness using health administrative data in Ontario, Canada following a national coding mandate: a validation study.

OBJECTIVES: Conducting longitudinal health research about people experiencing homelessness poses unique challenges. Identification through administrative data permits large, cost-effective studies; however, case validity in Ontario is unknown after a 2018 Canada-wide policy change mandating homelessness coding in hospital databases. We validated case definitions for identifying homelessness using Ontario health administrative databases after introduction of this coding mandate. STUDY DESIGN AND SETTING: We assessed 42 case definitions in a representative sample of people experiencing homelessness in Toronto (n = 640) from whom longitudinal housing history (ranging from 2018 to 2022) was obtained, and a randomly selected sample of presumably housed people (n = 128,000) in Toronto. We evaluated sensitivity, specificity, positive and negative predictive values, and positive likelihood ratios to select an optimal definition, and compared the resulting true positives against false positives and false negatives to identify potential causes of misclassification. RESULTS: The optimal case definition included any homelessness indicator during a hospital-based encounter within 180 days of a period of homelessness (sensitivity = 52.9%; specificity = 99.5%). For periods of homelessness with ≥1 hospital-based healthcare encounter, the optimal case definition had greatly improved sensitivity (75.1%) while retaining excellent specificity (98.5%). Review of false positives suggested that homeless status is sometimes erroneously carried forward in healthcare databases after an individual transitioned out of homelessness. CONCLUSION: Case definitions to identify homelessness using Ontario health administrative data exhibit moderate to good sensitivity and excellent specificity. Sensitivity has more than doubled since the implementation of a national coding mandate. Mandatory collection and reporting of homelessness information within administrative data present invaluable opportunities for advancing research on the health and healthcare needs of people experiencing homelessness.

PROTOCOL: Effectiveness of behavioral interventions for smoking cessation among homeless persons: A systematic review and meta-analysis.

This is the protocol for an updated Campbell systematic review. The objectives are as follows: To evaluate the effect of behavioral interventions on smoking cessation among homeless individuals.

The Link Between Childhood Abuse Experiences and Homeless People's Quality of Life: A Longitudinal Study.

Studies report a relatively high prevalence of childhood abuse experiences (CAE) among adult homeless people. Within homeless populations, people with CAE appear to be worse off than homeless people without such experiences. This study compares a broad set of factors influencing the quality of the daily lives of Dutch homeless people with and without CAE. It also examines the extent to which CAE are predictive of the rate of change in these factors 2.5 years after entering the social relief system. Data were used from an observational longitudinal multi-site cohort study following Dutch homeless people 2.5 years after entering the social relief system. The 4 constitutional conditions of the Social Quality Approach (living conditions, interpersonal embeddedness, societal embeddedness and self-regulation) were used to cluster the factors included in this study. Participants were interviewed twice, at baseline (N = 513) and at follow up (N = 378), using a quantitative questionnaire. At baseline and follow-up participants with CAE were more disadvantaged in each of the 4 conditions of social quality, except for societal embeddedness at follow-up. After 2.5 years, on average, all participants improved more or less at a similar rate on almost all factors, with a few exceptions: Significant differential changes over time were found regarding employment status, quality of relationships with family members and symptoms of depression and anxiety. Findings corroborate the broad, detrimental and persistent impact of CAE on the quality of daily lives of homeless people and the need for homelessness services to apply trauma-informed care.
