Multimorbidity among People Experiencing Homelessness-Insights from Primary Care Data

The effectiveness of psychosocial interventions for reducing problematic substance use, mental ill health, and housing instability in people experiencing homelessness in high income countries: A systematic review and meta-analysis

Background

Adults experiencing homelessness in high income countries often also face issues of problematic substance use, mental ill health, in addition to housing instability, so it is important to understand what interventions might help address these issues. While there is growing evidence of the effectiveness of psychosocial interventions for the general population, limited evidence exists specifically for those experiencing homelessness.

Objectives

To summarise the existing evidence of whether psychosocial interventions work in reducing problematic substance use, mental ill health, and housing instability for adults experiencing homelessness in high income countries.

Search Methods

We used searches undertaken for the Homelessness Effectiveness Evidence and Gap Map (EGM) 5th edition. These were supplemented with hand searches of key journals and a call for evidence.

Selection Criteria

We included all Randomised Control Trials and non-randomised studies where a comparison group was used and which examined psychosocial interventiONS for adults experiencing homelessness. 'Psychosocial intervention' is a broad term and covers several interventions, including cognitive behavioural therapy (CBT), contingency management, and motivational interviewing. We focused on studies that measure at least one of three outcomes: reduction in problematic substance use (alcohol and/or drugs); reduction in mental ill-health; reduction in housing instability.

Data Collection and Analysis

For included studies sourced from the EGM, we used the risk of bias assessments reported in the EGM. For included studies sourced from our own searches, we used the same tools used in the EGM to undertake our own assessments. We carried out meta-analysis where possible, and where not possible, presented included studies narratively.

Findings

We included 26 papers covering 23 individual intervention studies. All of the included studies were from the United States. Of the 26 papers, 14 were assessed as having medium or high risk of bias, with main issues being lack of masking/blinding, lack of power calculations, and high levels of drop-out.

Effectiveness of Psychosocial Interventions

We found that psychosocial interventions overall were better than standard care (-0.25 SD, 95% confidence intervals [CI] [-0.36, -0.13]). This finding covered six different interventions and was subject to a high level of between-study differences (heterogeneity). We also found that psychosocial interventions were more effective than standard care in relation to all three of our outcomes of interest, although were statistically significant only for substance abuse and mental ill-health. For substance use, we found an average effect size of (-0.34 SD, 95% CI [-0.48, -0.21]); for mental ill health of (-0.18 SD, 95% CI [-0.34, -0.01]); and for housing instability of (-0.10 SD, 95% [-0.90, 0.70]).

Effectiveness of Individual Psychosocial Interventions

We were able to undertake five meta-analyses (statistical summaries) with respect to four types of intervention: CBT, Contingency Management, Motivational Interviewing, and Brief Motivational Interventions, in relation to specific outcomes. Of these five analyses, we found significant effects for the effectiveness of Contingency Management in reducing problematic substance use (-0.49 SD, 95% CI [-0.85, -0.14]), and of Motivational Interviewing in reducing mental ill-health (-0.19 SD, 95% CI [-0.26, -0.12]). We also found non-significant effects in relation to CBT and reducing mental ill health (-0.30 SD, 95% CI [-0.61, 0.002]), Motivational Interviewing and reducing problematic substance use (-0.27 SD, 95% CI [-0.56, 0.01]), and Brief Motivational Interventions and reducing problematic substance use (-0.24 SD, 95% CI [-0.61, 0.13]). Meta-analysis was not possible for any other interventions or outcomes.

Author Conclusions

This systematic review sought to understand the effectiveness of psychosocial interventions for adults in high income countries experiencing homelessness, for reducing problematic substance use, reducing mental ill-health, and increasing housing stability. The review shows potential benefits of these interventions, with some encouraging results for some interventions and outcomes. Where we could calculate effect sizes, these were often small and, in many cases, crossed the line of no effect (i.e., there is a chance that they are equally or less effective than treatment as usual). Significant heterogeneity between studies and high rates of drop-out in many studies reduces the confidence in the interventions.There are some limitations with the evidence base. The included studies were entirely from the United States. There was a clear gender bias in the included studies, with nearly two-thirds of participants being men. (This is despite 4 of the 26 included studies focusing on women only.) We also found that the theoretical basis for the approach of interventions was not sufficiently considered, so it was difficult to understand why the intervention expected the outcomes they measured. Finally, many of the studies included were assessed as having high or medium risk of bias.

What they did next: Using follow-up phone calls to investigate health care access patterns of patients who take their own leave

OBJECTIVES

The purpose of the present study was to use telephone follow-up (TFU) to investigate the actions taken by patients after they took their own leave (TOL) from an ED, with a focus on priority groups who are at risk of experiencing health inequity. These included people experiencing homelessness (EH), people with a low socioeconomic status by index of relative socioeconomic disadvantage (IRSD) and First Nations people. The primary outcome was being seen by a general practitioner (GP) within 2 days of the TOL event. The utility of the TFU was also examined.

METHODS

This was an observational study of data collected during a quality improvement intervention at an inner-city, tertiary, teaching hospital in Melbourne from January to December 2022. Descriptive results were obtained from a TFU survey that was administered 24-48 h after the TOL event.

RESULTS

During the study period, 4209 patients TOL from the ED. Eight hundred forty-one of these were contacted and consented to the TFU survey. 97.7% of patients expressed gratitude at being followed up. Patients EH, compared to patients not EH, were less likely to have seen their GP within 2 days of TOL event (0.295 [0.132-0.661], P < 0.001). Both First Nations patients and those from low IRSD areas were as likely to have seen their GP within 2 days as other groups.

CONCLUSION

Patients EH were less likely to receive GP care within 2 days of TOL. Improving the access and acceptability of health care in these priority groups is important for achieving health equity.

Evaluation of a Virtual Health Hub for People Experiencing Homelessness in Sydney, Australia: Ensuring Physical and Psychological Primary Health Care in Crisis Accommodation

INTRODUCTION

Individuals experiencing homelessness have higher rates of chronic disease and face challenges accessing primary care. Virtual health care can reduce health inequity but needs user acceptance. A virtual health hub (VHH) for people experiencing homelessness in Sydney provided virtual GP and psychologist care within a crisis accommodation service. This included nursing assistance.

METHOD

The VHH evaluation assessed the feasibility of the service specifically examining accessibility, efficiency, costs, technology, quality, and outcomes through attendance data, patient measures, stakeholder interviews, and case studies.

FINDINGS

Data indicated 40% client utilisation with high attendance for GPs and/or psychologists. All clients reported a high quality of care, appointment benefits, understanding clinicians, and treatment help, and that privacy was maintained. If the VHH was not available, one-third would not have sought treatment. The majority agreed that virtual care was the same or better than in-person care. Only a few experienced technical issues. Service provider interviews indicated the benefits of accessible and affordable care, perceived reduced hospital presentations, staff time saved, and reduced client costs. Limitations were the lack of physical examinations and lack of follow-up due to temporary accommodation. Strong stakeholder partnerships enabled implementation success.

CONCLUSIONS

The VHH service is feasible and replicable with on-site assistance and stakeholder commitment.

The public health significance of prior homelessness: findings on multimorbidity and mental health from a nationally representative survey

AIMS

The associations of prior homelessness with current health are unknown. Using nationally representative data collected in private households in England, this study aimed to examine Common Mental Disorders (CMDs), physical health, alcohol/substance dependence, and multimorbidities in people who formerly experienced homelessness compared to people who never experienced homelessness.

METHODS

This cross-sectional study utilised data from the 2007 and 2014 Adult Psychiatric Morbidity Surveys. Former homelessness and current physical health problems were self-reported. Current CMDs, alcohol dependence and substance dependence were ascertained using structured validated scales. Survey-weighted logistic regression was used to compare multimorbidities (conditions in combination) for participants who formerly experienced homelessness with those who had never experienced homelessness, adjusting for sociodemographic characteristics, smoking status and adverse experiences. Population attributable fractions (PAFs) were calculated.

RESULTS

Of 13,859 people in the sample, 535 formerly experienced homelessness (3.6%, 95% CI 3.2-4.0). 44.8% of people who formerly experienced homelessness had CMDs (95% CI 40.2-49.5), compared to 15.0% (95% CI 14.3-15.7) for those who had never experienced homelessness. There were substantial associations between prior homelessness and physical multimorbidity (adjusted odds ratio [aOR] 1.98, 95% CI 1.53-2.57), CMD-physical multimorbidity (aOR 3.43, 95% CI 2.77-4.25), CMD-alcohol/substance multimorbidity (aOR 3.53, 95% CI 2.49-5.01) and trimorbidity (CMD-alcohol/substance-physical multimorbidity) (aOR 3.26, 95% CI 2.20-4.83), in models adjusting for sociodemographic characteristics and smoking. After further adjustment for adverse experiences, associations attenuated but persisted for physical multimorbidity (aOR 1.40, 95% CI 1.10-1.79) and CMD-physical multimorbidity (aOR 1.55, 95% CI 1.20-2.00). The largest PAFs were observed for CMD-alcohol/substance multimorbidity (17%) and trimorbidity (16%).

CONCLUSIONS

Even in people currently rehoused, marked inequities across multimorbidities remained evident, highlighting the need for longer-term integrated support for people who have previously experienced homelessness.

Logic modelling as hermeneutic praxis: Bringing knowledge systems into view during comprehensive primary health care planning for homelessness in Australia

Logic modelling is used widely in health promotion planning for complex health and social problems. It is often undertaken collaboratively with stakeholders across sectors that hold and enact different institutional approaches. We use hermeneutic philosophy to explore how knowledge is 'lived' by - and unfolds differently for - cross-sectoral stakeholders during comprehensive primary healthcare service planning. An Organisational Action Research partnership was established with a non-government organisation designing comprehensive primary health care for individuals experiencing homelessness in Adelaide, Australia. Grey literature, stakeholder input, academic feedback, a targeted literature review and evidence synthesis were integrated in iterative cycles to inform and refine the logic model. Diverse knowledge systems are active when cross-sectoral stakeholders collaborate on logic models for comprehensive primary health care planning. Considering logic modelling as a hermeneutic praxis helps to foreground and explore these differences. In our case, divergent ideas emerged in how health/wellbeing and trust were conceptualised; language had different meanings across sectors; and the outcomes and data sought were nuanced for various collaborators. We explicate these methodological insights and also contribute our evidence-informed, collaboratively-derived model for design of a comprehensive primary health care service with populations experiencing homelessness. We outline the value of considering cross-sectoral logic modelling as hermeneutic praxis. Engaging with points of difference in cross-sectoral knowledge systems can strengthen logic modelling processes, partnerships and potential outcomes for complex and comprehensive primary health care services.

The effectiveness of abstinence-based and harm reduction-based interventions in reducing problematic substance use in adults who are experiencing homelessness in high income countries: A systematic review and meta-analysis: A systematic review

Background

Homelessness is a traumatic experience, and can have a devastating effect on those experiencing it. People who are homeless often face significant barriers when accessing public services, and have often experienced adverse childhood events, extreme social disadvantage, physical, emotional and sexual abuse, neglect, low self-esteem, poor physical and mental health, and much lower life expectancy compared to the general population. Rates of problematic substance use are disproportionately high, with many using drugs and alcohol to deal with the stress of living on the street, to keep warm, or to block out memories of previous abuse or trauma. Substance dependency can also create barriers to successful transition to stable housing.

Objectives

To understand the effectiveness of different substance use interventions for adults experiencing homelessness.

Search Methods

The primary source of studies for was the 4th edition of the Homelessness Effectiveness Studies Evidence and Gaps Maps (EGM). Searches for the EGM were completed in September 2021. Other potential studies were identified through a call for grey evidence, hand-searching key journals, and unpacking relevant systematic reviews.

Selection Criteria

Eligible studies were impact evaluations that involved some comparison group. We included studies that tested the effectiveness of substance use interventions, and measured substance use outcomes, for adults experiencing homelessness in high income countries.

Data Collection and Analysis

Descriptive characteristics and statistical information in included studies were coded and checked by at least two members of the review team. Studies selected for the review were assessed for confidence in the findings. Standardised effect sizes were calculated and, if a study did not provide sufficient raw data for the calculation of an effect size, author(s) were contacted to obtain these data. We used random-effects meta-analysis and robust-variance estimation procedures to synthesise effect sizes. If a study included multiple effects, we carried out a critical assessment to determine (even if only theoretically) whether the effects are likely to be dependent. Where dependent effects were identified, we used robust variance estimation to determine whether we can account for these. Where effect sizes were converted from a binary to continuous measure (or vice versa), we undertook a sensitivity analysis by running an additional analysis with these studies omitted. We also assessed the sensitivity of results to inclusion of non-randomised studies and studies classified as low confidence in findings. All included an assessment of statistical heterogeneity. Finally, we undertook analysis to assess whether publication bias was likely to be a factor in our findings. For those studies that we were unable to include in meta-analysis, we have provided a narrative synthesis of the study and its findings.

Main Results

We included 48 individual papers covering 34 unique studies. The studies covered 15, 255 participants, with all but one of the studies being from the United States and Canada. Most papers were rated as low confidence (n = 25, or 52%). By far the most common reason for studies being rated as low confidence was high rates of attrition and/or differential attrition of study participants, that fell below the What Works Clearinghouse liberal attrition standard. Eleven of the included studies were rated as medium confidence and 12 studies as high confidence. The interventions included in our analysis were more effective in reducing substance use than treatment as usual, with an overall effect size of -0.11 SD (95% confidence interval [CI], -0.27, 0.05). There was substantial heterogeneity across studies, and the results were sensitive to the removal of low confidence studies (-0.21 SD, 95% CI [-0.59, 0.17] - 6 studies, 17 effect sizes), the removal of quasi-experimental studies (-0.14 SD, 95% CI [-0.30, 0.02] - 14 studies, 41 effect sizes) and the removal of studies where an effect size had been converted from a binary to a continuous outcome (-0.08 SD, 95% CI [-0.31, 0.15] - 10 studies, 31 effect sizes). This suggests that the findings are sensitive to the inclusion of lower quality studies, although unusually the average effect increases when we removed low confidence studies. The average effect for abstinence-based interventions compared to treatment-as-usual (TAU) service provision was -0.28 SD (95% CI, -0.65, 0.09) (6 studies, 15 effect sizes), and for harm reduction interventions compared to a TAU service provision is close to 0 at 0.03 SD (95% CI, -0.08, 0.14) (9 studies, 30 effect sizes). The confidence intervals for both estimates are wide and crossing zero. For both, the comparison groups are primarily abstinence-based, with the exception of two studies where the comparison group condition was unclear. We found that both Assertative Community Treatment and Intensive Case Management were no better than treatment as usual, with average effect on substance use of 0.03 SD, 95% CI [-0.07, 0.13] and -0.47 SD, 95% CI [-0.72, -0.21] 0.05 SD, 95% CI [-0.28, 0.39] respectively. These findings are consistent with wider research, and it is important to note that we only examined the effect on substance use outcomes (these interventions can be effective in terms of other outcomes). We found that CM interventions can be effective in reducing substance use compared to treatment as usual, with an average effect of -0.47 SD, 95% CI (-0.72, -0.21). All of these results need to be considered in light of the quality of the underlying evidence. There were six further interventions where we undertook narrative synthesis. These syntheses suggest that Group Work, Harm Reduction Psychotherapy, and Therapeutic Communities are effective in reducing substance use, with mixed results found for Motivational Interviewing and Talking Therapies (including Cognitive Behavioural Therapy). The narrative synthesis suggested that Residential Rehabilitation was no better than treatment as usual in terms of reducing substance use for our population of interest.

Authors' Conclusions

Although our analysis of harm reduction versus treatment as usual, abstinence versus treatment as usual, and harm reduction versus abstinence suggests that these different approaches make little real difference to the outcomes achieved in comparison to treatment as usual. The findings suggest that some individual interventions are more effective than others. The overall low quality of the primary studies suggests that further primary impact research could be beneficial.

Prehospital Care for Persons Experiencing Homelessness: A Cross-Sectional Survey of the Challenges, Experiences, and Perspectives of Operational EMS Agency Medical Directors

OBJECTIVE

Persons experiencing homelessness (PEH) are among the most vulnerable populations and experience significant health disparities. Nationally, PEH utilize Emergency Medical Services (EMS) at disproportionately higher rates than their housed peers. Developing optimal strategies to care for PEH has become critically important. However, limited data exists on best practices, challenges, and experiences of providing care to PEH. The objective of this study was to describe the experiences, challenges and perspectives of operational EMS agency medical directors in Los Angeles (LA) County as they confront the homelessness crisis.

METHODS

We performed a cross-sectional survey of 9-1-1 operational EMS agency medical directors in LA County, which has one of the largest populations of PEH nationally. Twenty-nine 9-1-1 operational EMS agencies operate in LA County. The link to an anonymous, web-based survey examining documentation, training, resources, operational impact, and care challenges was emailed to medical directors with three reminders during the study period (4/19/2023-9/15/2023).

RESULTS

Three quarters (75.9%; 22/29) of operational EMS agencies responded to the survey, with all questions answered in 69% (20/29) of surveys. Of these, 68.2% (15/22) of agencies document housing status and 75% (15/20) agreed or strongly agreed that homelessness presents operational challenges. No operational EMS agency reported adequate EMS clinician training on homelessness. Operational EMS agencies most commonly utilized domestic violence resources (43%, 9/21), social services (38%, 8/21), and law enforcement (38%, 8/21) services to assist PEH. Referrals were limited by accessibility (86%, 18/21), time (52%, 11/21), lack of awareness (52% 11/21) and lack of mandates (52%, 11/21). All operational EMS agencies agreed or strongly agreed that mental health and substance use disorders are major issues for PEH. The most common daily challenges reported were mental health (55%, 11/20), substance use (55%, 11/20), and patient resistance (35%, 7/20).

CONCLUSION

In LA County, EMS agencies experience important operational and clinical challenges in caring for PEH, with limited resources, minimal training, and high rates of substance use disorders and mental health comorbidities. Further prehospital research is essential to standardize documentation of housing status, to identify areas for intervention, increase linkage to services, and define best practices.

Health Technology Access and Peer Support Among Digitally Engaged People Experiencing Homelessness: Qualitative Study

BACKGROUND

Although the effects of digital health are receiving wide scientific attention, very little is known about the characteristics of digitally engaged people experiencing homelessness, especially in Central and Eastern Europe. Our previous research revealed a considerable level of internet use in the homeless population of Budapest, Hungary, for general purposes (350/662, 52.9%) and medical purposes (229/664, 34.6%). Moreover, a digitally engaged subgroup was identified (129/662, 19.5%).

OBJECTIVE

The aim of this exploratory study was to map out the resources, attitudes, and behaviors of digitally engaged homeless individuals in relation to digital technology to set the basis for potential health policy interventions, which will enable better access to health services through strengthening of the digital components of the existing health care system.

METHODS

Between August 18, 2022, and October 27, 2022, a total of 12 in-depth semistructured interviews were conducted in 4 homeless shelters in Budapest, Hungary. Upon analysis by 3 independent evaluators, 2 interviews were excluded. The interviewees were chosen based on purposive sampling with predefined inclusion criteria. Thematic analysis of the transcripts was conducted.

RESULTS

In the thematic analysis, 4 main themes (attitude, access, usage patterns, and solutions for usage problems) emerged. Health-related technology use mostly appeared in health information-seeking behavior. Online search for prescribed medications (5 interviews), active ingredients of medications (4 interviews), medicinal herbs believed to replace certain pills (2 interviews) or foods, and natural materials (1 interview) were mentioned. Moreover, mobile health app use (3 interviews) was reported. The intention to circumvent or check on mainstream health care solutions was mainly associated with previous negative experiences in the health care system. Several gaps in the daily use of technology were identified by the interviewees; however, more than half of the interviewees (6/10) turned out to be contact points for their peers for digital problem-solving or basic digital literacy skill enhancement in the homeless shelters. Furthermore, a lack of institutional support or special programs targeting senior clients was noted.

CONCLUSIONS

Digitally engaged homeless individuals might become mediators between their peers and comprehensive digital health programs. They have the trust of their peers, can recognize and harness the benefits of digital technology, and are able to provide meaningful help in technology- and usage-related issues through experience. Digital health services have great promise in community shelters for managing and preventing health issues, and digitally engaged individuals might be important for the success of such services.

Describing the development and implementation of a novel collaborative multidisciplinary approach to deliver foot health supports for individuals experiencing homelessness and its outcomes

Basic foot care is a real need of people experiencing homelessness. To improve access to foot health for this group, three services structured to provide healthcare support for people experiencing homelessness collaborated in metropolitan Melbourne, Australia: an established nurse-led Homeless Persons Program (HPP), a specialty community health podiatry clinic servicing people experiencing homelessness, and a charity supporting disadvantaged communities providing free socks, foot first aid kits and second-hand footwear for distribution by nurses and podiatrists of participating services. This paper outlines the implementation and evaluation of this collaboration. A four stage implementation approach was used, addressing: 1. Who needs to do what differently? 2. What are the barriers and enablers that need to be addressed? 3. Which intervention components could overcome the modifiable barriers and enhance the enablers? 4. How can the changes be measured? The evaluation prospectively collected information about how HPP nurses referred adults to podiatry, and whether the referred individuals accessed the podiatry clinic, the outcomes of the podiatry visit, and how many received footwear, socks and foot first aid kits provided by the non-profit organisation. Over 1st June 2019 and 31st December 2020, 52 individuals were identified as adults who could potentially benefit from podiatry by the HPP nurses, of which 33 accessed podiatry. Those who did not visit the podiatry clinic were more likely to be born outside of Australia, live in more precarious housing (crisis accommodation and rough sleeping), have slightly more predisposing factors for homelessness, but have fewer medical, psychological and cognitive conditions. A structured approach including processes, education, regular, outreach to youth refuges and formal outcome monitoring enabled foot health care access in people experiencing homelessness. Further research is needed to ascertain how to support participants at risk of foot problems to access podiatry before their foot health issue reaches crisis point.

A scoping review examining patient experience and what matters to people experiencing homelessness when seeking healthcare

BACKGROUND

Homelessness is associated with significant health disparities. Conventional health services often fail to address the unique needs and lived experience of homeless individuals and fail to include participatory design when planning health services. This scoping review aimed to examine areas of patient experience that are most frequently reported by people experiencing homelessness when seeking and receiving healthcare, and to identify existing surveys used to measure patient experience for this cohort.

METHODS

A scoping review was undertaken reported according to the PRISMA-ScR 2020 Statement. Databases were searched on 1 December 2022: MEDLINE, EMBASE, APA PsychINFO and CINAHL. Included studies focused on people experiencing homelessness, healthcare services and patient experience, primary research, published in English from 2010. Qualitative papers and findings were extracted and synthesized against a modified framework based on the National Institute for Health and Care Excellence guidelines for care for people experiencing homelessness, the Institute of Medicine Framework and Lachman's multidimensional quality model. People with lived experience of homelessness were employed as part of the research team.

RESULTS

Thirty-two studies were included. Of these, 22 were qualitative, seven quantitative and three mixed methods, from the United States of America (n = 17), United Kingdom (n = 5), Australia (n = 5) and Canada (n = 4). Health services ranged from primary healthcare to outpatient management, acute care, emergency care and hospital based healthcare. In qualitative papers, the domains of 'accessible and timely', 'person-centred', and values of 'dignity and respect' and 'kindness with compassion' were most prevalent. Among the three patient experience surveys identified, 'accessible and timely' and 'person-centred' were the most frequent domains. The least frequently highlighted domains and values were 'equitable' and 'holistic'. No questions addressed the 'safety' domain.

CONCLUSIONS

The Primary Care Quality-Homeless questionnaire best reflected the priorities for healthcare provision that were highlighted in the qualitative studies of people experiencing homelessness. The most frequently cited domains and values that people experiencing homelessness expressed as important when seeking healthcare were reflected in each of the three survey tools to varying degrees. Findings suggest that the principles of 'Kindness and compassion' require further emphasis when seeking feedback on healthcare experiences and the domains of 'safety', 'equitable', and 'efficiency' are not adequately represented in existing patient experience surveys.

Critical Success Factors for Intersectoral Collaboration: Homelessness and COVID-19 - Case Studies and Learnings from an Australian City

Introduction

The COVID-19 pandemic disproportionally impacted people experiencing homelessness, including people sleeping rough, people in temporary accommodation and those living in boarding houses. This paper reports on intersectoral responses across six health and social care agencies in Inner Sydney, New South Wales, Australia. Prior to the pandemic the six agencies had established an Intersectoral Homelessness Health Strategy (IHHS), in recognition of the need for intersectoral collaboration to address the complex health needs of people experiencing homelessness.

Description

The governance structure of the IHHS provided a platform for several innovative intersectoral responses to the pandemic. A realist informed framework was used to select, describe, and analyse case studies of intersectoral collaboration.

Discussion

The resultant six critical success factors (trust, shared ways of working, agile collaboration, communication mechanisms, authorising environment, and sustained momentum), align with the existing literature that explores effective intersectoral collaboration in complex health or social care settings. This paper goes further by describing intersectoral collaboration 'in action', setting a strong foundation for future collaborative initiatives.

Conclusion

While there is no single right approach to undertaking intersectoral collaboration, which is highly context specific, the six critical success factors identified could be applied to other health issues where dynamic collaboration and integration of healthcare is needed.

Involving people with lived experience of homelessness in palliative and end of life care research: key considerations from experts in the field

BACKGROUND

Co-production of research aims to include people with lived experience of a phenomena throughout the research process. People experiencing homelessness often experience advance ill-health at a young age, yet access palliative care services at a disparately low rate to the level of palliative care need. The voices of people experiencing homelessness are infrequently heard throughout palliative care research, despite the complexities and intricacies of the area.

AIM

To explore the experiences of experts in the field to identify key context considerations for involving people with lived experience of homelessness in palliative and end of life care research.

METHODS

Qualitative study comprising two data collection streams: interviews with professionals with experience of involving people experiencing homelessness in their work, and focus groups with people with lived experience (PWLE) of homelessness. Data were analysed using iterative, reflexive thematic analysis. Patient and Public Involvement contributors gave feedback on themes.

RESULTS

A total of 27 participants took part in semi-structured interviews (N = 16; professionals) or focus groups (N = 11; PWLE homelessness). Key considerations of involving people experiencing homelessness in palliative and end of life care research were developed into four key themes: complexity of lived experience of homelessness; representation of homelessness within experts by experience; professionalising lived experience; and methods for involvement.

CONCLUSIONS

Involvement of people with lived experience of homelessness is important in developing palliative care research. This paper begins to outline some contextual considerations for promoting involvement in a complex and intricate field of research.

Spatial Vision Inequalities: A Literature Review of the Impact of Place on Vision and Eye Health Outcomes

"Neighborhood and built environment" is one of the five domains of social determinants of health that has been outlined by Healthy People 2030, and this domain impacts an individual's well-being, health, and quality of life. Social risk factors (SRFs) in the neighborhood and built environment domain include unstable or unsafe housing, poor access to transportation, lack of green spaces, pollution, safety concerns, and neighborhood measures of inequity. In this narrative literature review, we assess the relationship between neighborhood and built environment SRFs and eye health and vision outcomes. We explain how mapping neighborhood-level SRFs may be used to advance health equity in the field of eye health and vision care.

Feasibility of telehealth counselling pilot for people experiencing homelessness and/or complex needs: During COVID-19 and beyond

ISSUES ADDRESSED

People experiencing homelessness and/or complex needs often require targeted health services to address unique vulnerabilities. COVID-19 restrictions acted as a barrier for this group accessing health and alcohol and other drug (AOD) treatment services. The Haymarket Foundation, an accommodation and health facility in Australia, transitioned from in-person AOD-counselling services to online consultations. Clients accessing these services were tracked, from March 2019 to November 2020, to assess the impact of the switch to telehealth on client retention.

METHODS

Qualitative analysis of Haymarket clients' service experience surveys and quantitative descriptives of "no-show" (nonattended sessions) rates and survival analysis of client treatment separations were completed to assess the impact of transitioning to telehealth on client retention.

RESULTS

Although the initial transition to telehealth in March 2020 minimally impacted client no-show rates, reinstated government restrictions in June/July 2020 coincided with increasing no-shows and a substantial increase in treatment exits without notice, especially amongst males. Qualitative analysis showed clients had mixed feelings towards telehealth: some attributed their dissatisfaction to the inability to build rapport with their counsellor online, or with COVID-19 in general. Others appreciated the availability and genuine care of their counsellors through either setting.

CONCLUSIONS

Telehealth may be a feasible replacement for face-to-face AOD counselling for people experiencing homelessness, however further investigation needs to be conducted to understand factors associated with improved client retention. SO WHAT?: This pilot demonstrates telehealth may be a feasible ongoing feature of health promotion for vulnerable high-needs populations, including people experiencing homelessness who use substances.

Correlates of Homelessness Among Adults with Personality Disorder

Although personality disorders (PDs) are more common among persons experiencing homelessness than the general population, few studies have investigated the risk of experiencing homelessness among persons with PDs. This study seeks to identify the demographic, socioeconomic, and behavioral health correlates of past-year homelessness among persons with antisocial, borderline, and schizotypal PDs. Nationally representative data of the civilian, noninstitutionalized population of the United States was used to identify correlates of homelessness. Descriptive statistics and bivariate associations between variables and homeless status were summarized prior to conducting several multivariate logistic regression models to identify correlates of homelessness. Main findings revealed positive associations between poverty, relationship dysfunction, and lifetime suicide attempt with homelessness. In the antisocial PD (ASPD) and borderline PD (BPD) models, comorbid BPD and ASPD, respectively, were associated with higher odds of past-year homelessness. Findings underscore the importance of poverty, interpersonal difficulties, and behavioral health comorbidities on homelessness among persons with ASPD, BPD, and schizotypal PD. Strategies to promote economic security, stable relationships, and interpersonal functioning may buffer against the effects of economic volatility and other systemic factors that could contribute to homelessness and persons with PD.

Optimising Access to Healthcare for Patients Experiencing Homelessness in Hospital Emergency Departments

The ED is often the first and sometimes the only place where people experiencing homelessness seek medical assistance. While access to primary healthcare is a preferable and more cost-effective alternative to ED, for many reasons, people experiencing homelessness are much less likely to have a regular General Practitioner compared to those living in stable accommodation. Drawing on a growing body of emergency care and homelessness literature and practice, we have synthesised four potential interventions to optimise access to care when people experiencing homelessness present to an ED. Although EDs are in no way responsible for resolving the complex health and social issues of their local homeless population, they are a common contact point and therefore present an opportunity to improve access to healthcare.

PROTOCOL: The effectiveness of psychosocial interventions for reducing problematic substance use, improving mental health, and improving housing stability for adults experiencing homelessness: A systematic review and meta-analysis

This systematic review is part of a broader evidence synthesis which aims to produce two systematic reviews to address a significant gap in the evidence base identified by Luchenski et al. (2018) and by (White, 2018). The first review (which is the subject of this protocol) will use meta-analysis to examine the effectiveness of different psychosocial interventions in (1) reducing problematic substance use; (2) improving mental health; and (3) improving housing stability for adults experiencing homelessness. The second review (which is covered by a separate title registration and protocol) will be of the experiences of adults experiencing homelessness when accessing or using psychosocial interventions, and will be a qualitative evidence synthesis using thematic synthesis (Thomas & Harden, 2008).

PROTOCOL: The experiences of adults experiencing homelessness when accessing and using psychosocial interventions: A systematic review and qualitative evidence synthesis

The systematic review set out in this protocol is part of a broader evidence synthesis which intends to produce two systematic reviews to address a significant gap in the evidence base identified by Luchenski et al. (2018) and by White and Narayanan (2021). This review (the focus of this protocol) will be of the experiences of adults experiencing homelessness when accessing and using psychosocial interventions. This review of qualitative data will use thematic synthesis to analyse these experiences as faced by this population when accessing and using psychosocial interventions.

Multiple Long-Term Conditions (MLTC) and the Environment: A Scoping Review

Background: Multiple Long Term conditions (MLTC) are a major health care challenge associated with high service utilisation and expenditure. Once established, the trajectory to an increased number and severity of conditions, hospital admission, increased social care need and mortality is multifactorial. The role of wider environmental determinants in the MLTC sequelae is unclear. Aim: the aim of this review was to summarise and collate existing evidence on environmental determinants on established MLTC. Methods: comprehensive search of Medline, Embase, Cochrane, CINAHL and Bielefeld Academic Search Engine (BASE), from inception to 4th June 2022 in addition to grey literature. Two authors independently screened and extracted papers. Disagreements were resolved with a third author. Results: searches yielded 9079 articles, 12 of which met the review's inclusion criteria. Evidence of correlations between some environmental determinants and increased or decreased risks of MLTC were found, including the quality of internal housing/living environments, exposure to airborne environmental hazards and a beneficial association with socially cohesive, accessible and greener neighbourhood environments. Conclusions: The majority of the 12 included papers focused on the built and social environments. The review uncovered very limited evidence, indicating a need for further research to understand the role of environmental determinants in MLTC.
