Research priorities in healthcare of persons experiencing homelessness: outcomes of a national multi-disciplinary stakeholder discussion in the United Kingdom

Pharmacy Homeless Outreach Engagement Non-medical Independent Prescribing Rx (PHOENIx) Community Pharmacy-Based Pilot Randomized Controlled Trial

Randomized controlled trials (RCTs) aiming to address the multiple health and social challenges of people experiencing homelessness (PEH) are lacking. Here we report the findings from a multicenter, open, pilot RCT. The intervention involved independent prescriber pharmacist from the National Health Service working on outreach in partnership with dedicated workers from Homeless Voluntary Charity or Social Enterprises (HVCSEs) (Pharmacist and third sector charity worker integrated Homeless Outreach Engagement Non-medical Independent prescriber Rx'-PHOENIx) in low threshold HVCSE venues or temporary accommodation addressing PEH participants' health and wider needs through repeated outreach. The trial aimed to investigate whether sufficient numbers of participants could be recruited, retained, the intervention delivered as planned, and sufficient data collected to inform a subsequent definitive RCT. Clinical outcomes were also collected at follow-up (6 months). Participants were recruited from five community pharmacies and nearby venues in urban centers of Glasgow-Scotland and Birmingham-England, then randomized one-to-one into PHOENIx intervention in addition to usual care (UC) or UC only. A priori progression criteria were achieved: 55% of those assessed as eligible were recruited; at 6 months, 72% remained in the study, 91% had emergency department and mortality data available, and 72% completed questionnaire booklets. Fifty-three percent of participants received at least 50% of the planned PHOENIx intervention consultations (in-person or phone) at 6 months. Signs of improvement in clinical outcomes in the PHOENIx group included fewer ambulance call-outs, ED visits, and hospitalizations; higher outpatient attendances; and higher scores on self-reported health-related quality of life. A definitive RCT is merited.

Patient and Public Involvement in Research Evaluating Integrated Care for People Experiencing Homelessness: Findings From the PHOENIx Community Pharmacy Pilot Randomised-Controlled Trial

INTRODUCTION

There is a paucity of research on and a limited understanding of patient and public involvement (PPI) in the context of research in homelessness and, in particular, direct involvement of people with lived and living experience of homelessness (PEH) as expert advisors. We aim to report on outcomes and reflections from lived experience advisory panel (LEAP) meetings and PPI activities, held throughout the study lifecycle of a pilot randomised-controlled trial (RCT) focused on evaluating integrated health and practical support for PEH.

METHODS

Community Pharmacy Homeless Outreach Engagement Non-medical Independent prescribing Rx (PHOENIx Community Pharmacy RCT) is an integrated health and social care intervention for people experiencing homelessness who present to community pharmacy. Intervention includes weekly support from a pharmacist prescriber and a third sector support worker for up to 6 months. PPI activities undertaken throughout the study were documented, including outcomes of LEAP meetings. Outcome reporting followed Guidance for Reporting Involvement of Patients and the Public 2 Short Form (GRIPP2-SF).

RESULTS

In total, 17 members were recruited into the LEAP; six meetings (three in two study sites) were held. PPI input was also received through representation from homelessness third sector organisation staff as study co-applicants and core membership in the trial steering committee. Together, the PPI activities helped shape the study proposal, design of study materials, data analysis and dissemination materials. LEAP panel members offered valuable input via their experience and expertise into the delivery and refinement of interventions. Although longitudinal input was received from some LEAP members, ensuring repeat attendance in the pre-planned meetings was challenging.

CONCLUSION

People who face social exclusion and marginalisation can provide highly valuable input as equal partners in co-design and delivery of interventions seeking to improve their health and well-being. Fluid membership and flexible methods of seeking and incorporating advice can offer pragmatic approaches to minimising barriers to continued involvement in research.

PATIENT OR PUBLIC CONTRIBUTION

This study reports findings and learning relevant to involvement of people with lived and living experience of homelessness as advisors in a research study. It is important for researchers to offer fluid memberships and use diverse methods to receive input from lived experience members, as traditional PPI methodology may be insufficient to ensure inclusivity. Staff and volunteers from third sector organisations were important PPI partners who bring their experience based on frontline service provision, often as the first port of call for people experiencing severe and multiple disadvantage.

Hostel support workers' experiences navigating healthcare alongside people experiencing homelessness: a qualitative study in the UK

OBJECTIVES

This study aimed to explore how hostel support workers (HSWs) experience navigating healthcare alongside people experiencing homelessness (PEH). PEH experience poor health outcomes, increased mortality and face many barriers when accessing healthcare. HSWs have a dynamic and holistic role, working with PEH to navigate access to health and social care, whilst facilitating independence. HSWs have been described as important in addressing barriers to access and linking healthcare and PEH. However, HSWs' experiences navigating this role across sectors remains underexplored.

DESIGN

In this qualitative study, semistructured interviews were conducted, and phenomenological thematic analysis was performed.

SETTING

Interviews were conducted with participants from 13 hostels across four UK counties.

PARTICIPANTS

17 HSWs were interviewed, with experience in their role ranging from 3 months to over 10 years.

RESULTS

Three themes were identified.HSWs feeling stigmatised by healthcare staff (HCS), including power inequalities between HSWs and HCS, and the impact of stigma against PEH in healthcare on HSWs.Working across sectors, including both collaborative and disconnected experiences.In-reach and its role in linking PEH and healthcare. This included the contrasting subthemes of in-reach as an effective link versus in-reach being an impractical and unsustainable solution.

CONCLUSIONS

Cross-sector collaboration has been recognised as an effective way to increase healthcare access and improve outcomes for Inclusion Health Groups, including PEH. This has been further highlighted by the formation of Integrated Care Systems, which strive to bring sectors together to tackle inequalities in outcomes, experience and access. Collaborative relationships between sectors, that is, hostels and healthcare, are vital for increasing healthcare access for PEH. We explored the experiences of HSWs navigating healthcare access for this marginalised population. Recognising and understanding these experiences are the first steps in building collaborative cross-sector relationships to improve healthcare accessibility, experiences and outcomes for PEH.

Exploring the Role of Rehabilitation Medicine within an Inclusion Health Context: Examining a Population at Risk from Homelessness and Brain Injury in Edinburgh

People experiencing homelessness are at risk from a number of comorbidities, including traumatic brain injury, mental health disorders, and various infections. Little is known about the rehabilitation needs of this population. This study took advantage of unique access to a specialist access GP practice for people experiencing homelessness and a local inclusion health initiative to explore the five-year period prevalence of these conditions in a population of people experiencing homelessness through electronic case record searches and to identify barriers and facilitators to healthcare provision for this population in the context of an interdisciplinary and multispecialist inclusion health team through semi-structured interviews with staff working in primary and secondary care who interact with this population. The five-year period prevalence of TBI, infections, and mental health disorders was 9.5%, 4%, and 22.8%, respectively. Of those who had suffered a brain injury, only three had accessed rehabilitation services. Themes from thematic analysis of interviews included the impact of psychological trauma, under-recognition of the needs of people experiencing homelessness, resource scarcity, and the need for collaborative and adaptive approaches. The combination of quantitative and qualitative data suggests a potential role for rehabilitation medicine in inclusion health initiatives.

Acute paediatric inpatient care of children and young people admitted with self-harm or eating disorders: A single centre evaluation

In the United Kingdom, the prevalence of children and young people (CYP) accessing acute paediatric inpatient care with mental health problems is increasing, with self-harm and eating disorders particularly prevalent. This study evaluated CYP experiences of being in receipt of acute paediatric inpatient care following either self-harm or crisis stemming from an eating disorder to inform domains for a person-centred outcome measure (PCOM). A series of stakeholder engagement events were conducted between April and July 2015 where creative approaches were used to explore stakeholder experiences of care and to identify outcome domains that were subsequently prioritised using a Nominal Group Technique. Data were analysed using inductive thematic approach, with significance scores calculated for domain statements. Ninety-six stakeholders (15 CYP, eight parents and carers, and 73 professionals) participated. Findings showed five priority PCOM domains: privacy and surveillance; holistic care; making choices, appropriate communication; working together to achieve care goals; and respect and empowerment. This single centre evaluation highlights the need for a PCOM to be developed for this patient group that comprehensively reflects stakeholders' expectations in order to inform improvements to quality of acute paediatric care.

Relations between Affect, Self-Efficacy, and Alcohol Expectancies in Adults Experiencing Homelessness

Background

Alcohol misuse is higher among adults experiencing homelessness (AEH) compared to housed adults. Greater expectancy that alcohol will improve mood, negative affect, and lower self-efficacy have been linked to alcohol misuse in AEH. However, little is known about the momentary relationships between affect, alcohol expectancies, and self-efficacy to avoid alcohol in AEH. To our knowledge, this is the first study to examine these constructs in a sample of AEH. Methods: AEH (n = 72; M age = 47, 85% Male, 68% Non-White) completed smartphone-based ecological momentary assessments 5x/day for four weeks. Generalized multilevel modeling examined the association between concurrent momentary ratings of (1) expectancy that alcohol would improve mood and negative and positive affect and (2) self-efficacy to do something other than drink to improve mood and negative and positive affect.

Results

Momentary reports of increased negative affect were associated with greater expectancy that alcohol would improve mood (b = 0.25, p < 0.01), whereas momentary reports of increased positive affect were associated with less expectancy that alcohol would improve mood (b = -0.11, p < 0.01). Increased momentary negative affect was associated with less self-efficacy to improve mood without alcohol (b = -0.09, p = 0.03), but momentary reports of increased positive affect were associated with greater self-efficacy to do something other than drink to improve mood (b = 0.18, p < 0.01).

Conclusion

It may be important to deliver real-time treatment messages suggesting alternatives to drinking and/or ways to boost self-efficacy during moments when negative affect is high.

Priority healthcare needs amongst people experiencing homelessness in Dublin, Ireland: A qualitative evaluation of community expert experiences and opinions

In light of evidence that housing-related disparities in mortality are worsening over time, this study aimed to explore the perspectives of experts working in homeless health and addiction services on priority healthcare needs amongst people experiencing homelessness in Dublin, Ireland, a city facing problematic increases in homelessness. As part of a larger qualitative study, a series of semi-structured interviews were carried out with 19 community experts followed by inductive thematic framework analysis to identify emergent themes and sub-themes relating to priority healthcare needs. At the societal level, community experts identified a need to promote a culture that values health equity. At the policy level, accelerating action in addressing health inequalities was recommended with an emphasis on strategic planning, Housing First, social support options, interagency collaboration, improved data linkage and sharing, and auditing. At the health services level, removing barriers to access will require the provision of more and safer mental health, addiction, women-centred, and general practice services; resolved care pathways in relation to crisis points and multi-morbidity; expanded trauma-informed education and training and hospital-led Inclusion Health programmes; and outreach programmes and peer support for chronic disease management. The voices of people experiencing homelessness, including representatives from specific homeless groups such as migrants, youth, and the elderly, must be thoroughly embedded into health and social service design and delivery to facilitate impactful change.

The Impact of Being Homeless on the Clinical Outcomes of COVID-19: Systematic Review

Objective: The homeless population experiences inequality in health compared with the general population, which may have widened during the COVID-19 pandemic. However, the impact of being homeless on the outcomes of COVID-19 is uncertain. This systematic review aimed to analyse the impact of experiencing homelessness on the clinical outcomes of COVID-19, including the effects on health inequalities. Methods: A review protocol was developed and registered in PROSPERO (PROSPERO registration 2022 CRD42022304941). Nine databases were searched in November 2022 to identify studies on homeless populations which contained primary research on the following outcomes of COVID-19: incidence, hospitalisation, mortality, long COVID, mental wellbeing, and evidence of inequalities. Included studies were summarised with narrative synthesis. Results: The searches yielded 8,233 initial hits; after screening, 41 studies were included. Overall, evidence showed that those in crowded living settings had a higher risk of COVID-19 infection compared to rough sleepers and the general population. The homeless population had higher rates of hospitalisation and mortality than the general population, lower vaccination rates, and suffered negative mental health impacts. Conclusion: This systematic review shows the homeless population is more susceptible to COVID-19 outcomes. Further research is needed to determine the actual impact of the pandemic on this population, and of interventions to mitigate overall risk, given the low certainty of findings from some of the low-quality evidence available. In addition, further research is required to ascertain the impact of long COVID on those experiencing homelessness, since the present review yielded no studies on this topic.

Key causes and long-term trends related to emergency department and inpatient hospital admissions of homeless persons in England

BACKGROUND

It is estimated that approximately 300,000 people are experiencing homelessness in England. The aim of this study was to evaluate key causes and long-term trends of emergency departments (EDs) and in hospital inpatient admissions of persons experiencing homelessness in England.

METHODS

ED and hospital inpatient admissions data were obtained from Hospital Episode Statistics (HES) covering all National Health Service (NHS) England hospitals. Anyone identified or declared to be experiencing homelessness during the service usage are recorded in HES datasets. Data were extracted for the 10-year study period and compared to the general population, which includes all patients attending the ED or admitted to inpatient care in England.

RESULTS

Drug- and alcohol-related causes contribute to the most frequent reasons for attendance and admissions of persons experiencing homelessness in the ED and inpatient respectively. A total of 30,406 ED attendances were recorded for persons experiencing homelessness in the year 2018/2019 (+ 44.9% rise vs 2009/10) of which injuries and poisoning respectively represented 21.8% and 17.9% of all persons experiencing homelessness presentations to the ED. Poisoning (including drug overdose) represented only 1.9% of all attendances by the general population during the same study year (rate ratio vs general populations 9.2 95% CI 9.0-9.4). High mortality rates were observed in relation to presentations attributed to drug- and alcohol-related causes. A total of 14,858 persons experiencing homelessness inpatient admissions were recorded in 2018/2019 (+ 68.6% vs 2009/2010). Psychoactive substance use constituted 12.7% of all admissions in 2018/2019 compared to 0.4% of in the general populations (rate ratio: 33.3, 95% CI: 31.9-34.7). There was a 44.3% rise in the number of admissions related to poisoning in the study period amongst persons experiencing homelessness in England (vs 14.2% in general population).

CONCLUSION

Marked disparities around primary causes of ED and inpatient admissions were identified between persons experiencing homelessness and the general population. There is a continued need for prevention measures to reduce the prevalence of drug and alcohol, injury and poisoning-related admissions to the ED, enhanced service provision at the community level, and multisector collaborations. These initiatives should maximise opportunities for early interventions and improve outcomes for persons experiencing homelessness, including increased accessibility of healthcare and mental health services, particularly in areas that demonstrate increasing ED and inpatient attendance rates over time.

Protocol for a pilot randomised controlled trial to evaluate integrated support from pharmacist independent prescriber and third sector worker for people experiencing homelessness: the PHOENIx community pharmacy study

BACKGROUND

People experiencing homelessness (PEH) have complex health and social care needs and most die in their early 40 s. PEH frequently use community pharmacies; however, evaluation of the delivery of structured, integrated, holistic health and social care intervention has not been previously undertaken in community pharmacies for PEH. PHOENIx (Pharmacy Homeless Outreach Engagement Non-medical Independent prescribing Rx) has been delivered and tested in Glasgow, Scotland, by NHS pharmacist independent prescribers and third sector homelessness support workers offering health and social care intervention in low threshold homeless drop-in venues, emergency accommodation and emergency departments, to PEH. Building on this work, this study aims to test recruitment, retention, intervention adherence and fidelity of community pharmacy-based PHOENIx intervention.

METHODS

Randomised, multi-centre, open, parallel-group external pilot trial. A total of 100 PEH aged 18 years and over will be recruited from community pharmacies in Glasgow and Birmingham. PHOENIx intervention includes structured assessment in the community pharmacy of health, housing, benefits and activities, in addition to usual care, through weekly visits lasting up to six months. A primary outcome is whether to proceed to a definitive trial based on pre-specified progression criteria. Secondary outcomes include drug/alcohol treatment uptake and treatment retention; overdose rates; mortality and time to death; prison/criminal justice encounters; healthcare utilisation; housing tenure; patient-reported measures and intervention acceptability. Analysis will include descriptive statistics of recruitment and retention rates. Process evaluation will be conducted using Normalisation Process Theory. Health, social care and personal resource use data will be identified, measured and valued.

DISCUSSION

If the findings of this pilot study suggest progression to a definitive trial, and if the definitive trial offers positive outcomes, it is intended that PHOENIx will be a publicly funded free-to-access service in community pharmacy for PEH. The study results will be shared with wider stakeholders and patients in addition to dissemination through medical journals and scientific conferences.

Barriers and facilitators to refugees, asylum seekers and people experiencing homelessness accessing non hospital based care: A mixed methods systematic review protocol

Context: Social exclusion is characterised by and represents a form of disadvantage and marginalisation of vulnerable groups of people in society, who cannot fully participate in the normal activities of daily living.  Socially excluded groups consist of, but are not limited to the following groups: people experiencing homelessness, asylum seekers and refugees.  People from socially excluded groups have complex healthcare needs including infectious and non-communicable diseases. People from socially excluded groups tend to present more to the acute hospital setting as emergency presentations.  Little is known about barriers and facilitators experienced by these groups to accessing non hospital based care. Objectives: This mixed methods systematic review, will critically examine the concept of barriers and facilitators for refugees, asylum seekers and people experiencing homelessness, to accessing non hospital based care. Methods:  This methodological review will follow the Joanna Briggs Institute guidance for conducting mixed methods reviews.  The following databases will be searched: Central Medline, PubMed, Embase, CINAHL, and the Cochrane Library. Relevant grey literature will be included. Title and abstract screening, followed by full-text screening will be undertaken independently by two reviewers. The Joanna Briggs Institute extraction tool will be adapted for data extraction.   Discussion: This mixed method review will comprehensively evaluate quantitative and qualitative data, synthesise both barriers and facilitators and follow a systematic approach through establishing use of mixed methods research across a number of marginalised groups, and how they affect accessing non hospital based care.   It will explore conceptual models of access to healthcare and how they influence these factors.

Clinical pharmacists in primary care general practices: evaluation of current workforce and their distribution

BACKGROUND

General practices in primary care across England are increasingly employing clinical pharmacists to help tackle the workforce crisis and alleviate pressure. Clinical pharmacists can provide administrative and clinical duties, including non-medical prescribing, advice on polypharmacy and medicines optimisation. The aim of this study was to investigate the distribution of clinical pharmacists in general practice across England, and explore the relationship between the distribution and regional demography.

METHODS

This study used publicly available government database from various sources pertaining to primary care general practice workforce and population demographics of England. The number and distribution of pharmacists working within general practices in England were analysed and compared across practices considering general practitioner (GP), nurse and patient population in the practices, patients age ≥ 65 years and over and the Index of Multiple Deprivation (IMD) scores.

RESULTS

Twenty two percentage (1469 of 6674) of practices in England were found to have access to a clinical pharmacist, equating to 1358 full-time equivalent (FTE) pharmacists and a mean pharmacist FTE of 10.07 (95% CI 8.40, 11.75, SD = 9.84) per Clinical Commissioning Group (CCG). A significant relationship between pharmacist FTE and the number of patients 65 years and older [r (132) = 0.75, P < 0.001)] was observed; however, the distribution was not related to population deprivation scores.

CONCLUSIONS

Approximately one in five general practices in England have access to a clinical pharmacist. Further research is needed to ensure wider and equitable distribution based on workforce needs and practice population demography.

Hospital-based preventative interventions for people experiencing homelessness in high-income countries: A systematic review

BACKGROUND

People experiencing homelessness have significant unmet needs and high rates of unplanned care. We aimed to describe preventative interventions, defined in their broadest sense, for people experiencing homelessness in a hospital context. Secondary aims included mapping outcomes and assessing intervention effectiveness.

METHODS

We searched online databases (MEDLINE, Embase, PsycINFO, HMIC, CINAHL, Web of Science, Cochrane Library) from 1999-2019 and conducted backward and forward citation searches to 31 December 2020 (PROSPERO CRD42019154036). We included quantitative studies in emergency and inpatient settings measuring health or social outcomes for adults experiencing homelessness in high income countries. We assessed rigour using the "Quality Assessment Tool for Quantitative Studies" and summarised findings using descriptive quantitative methods, a binomial test, a Harvest Plot, and narrative synthesis. We used PRISMA and SWiM reporting guidelines.

FINDINGS

Twenty-eight studies identified eight intervention types: care coordination (n=18); advocacy, support, and outreach (n=13); social welfare assistance (n=13); discharge planning (n=12); homelessness identification (n=6); psychological therapy and treatment (n=6); infectious disease prevention (n=5); and screening, treatment, and referrals (n=5). The evidence strength was weak (n=16) to moderate (n=10), with two high quality randomised controlled trials. We identified six outcome categories with potential benefits observed for psychosocial outcomes, including housing (11/13 studies, 95%CI=54.6-98.1%, p=0.023), healthcare use (14/17, 56.6-96.2%, p=0.013), and healthcare costs (8/8, 63.1-100%, p=0.008). Benefits were less likely for health outcomes (4/5, 28.3-99.5%, p=0.375), integration with onward care (2/4, 6.8-93.2%, p=1.000), and feasibility/acceptability (5/6, 35.9-99.6%, p=0.219), but confidence intervals were very wide. We observed no harms. Most studies showing potential benefits were multi-component interventions.

INTERPRETATION

Hospital-based preventative interventions for people experiencing homelessness are potentially beneficial, but more rigorous research is needed. In the context of high needs and extreme inequities, policymakers and healthcare providers may consider implementing multi-component preventative interventions.

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.

Digital Technology Access and Health-Related Internet Use Among People Experiencing Homelessness in Hungary: Quantitative Survey

Background

In recent years, there has been an increase in the use of digital technology for personal health and well-being. Previous research has revealed that these technologies might provide vulnerable populations, including those who are homeless, better access to health services and thus a greater chance of more personalized care.

Objective

However, little is known about the relationship between technology and health among people experiencing homelessness in Central and Eastern Europe. This study is part of a series of studies by the Digital Health Research Group at Semmelweis University (Budapest, Hungary) in cooperation with the Hungarian Charity Service of the Order of Malta; it aims to assess the existing technological resources available for the homeless population and their health-related internet use characteristics to set the ground for potential health policy interventions, enabling better access to health services by strengthening the digital components of the existing health care system.

Methods

Between April 19, 2021, and August 11, 2021, a total of 662 people from 28 institutions providing social services for people experiencing homelessness in Budapest, Hungary, were surveyed about their access to digital tools and internet use patterns. For selected questions, the responses of a representative sample of the Hungarian population were used for comparison as the reference group. Chi-square tests and logistic regression analyses were performed to identify variables affecting internet use for health-related reasons.

Results

The results demonstrated a considerable level of internet use in the homeless population; 52.9% (350/662) of the respondents used the internet frequently compared with 81.3% (1220/1500) of the respondents in the reference group. Among the homeless group, 69.6% (461/662) of the respondents reported mobile phone ownership, and 39.9% (264/662) of the respondents added that it had a smartphone function. Moreover, 11.2% (70/662) of the respondents had already used a health mobile app, and 34.6% (229/662) of the respondents had used the internet for medical purposes. On the basis of these characteristics, we were able to identify a broadly defined, digitally engaged group among people experiencing homelessness (129/662, 19.5%). This subpopulation was inclined to benefit from digitalization related to their personal health. Multivariate analysis demonstrated that internet use for health reasons was more significant for younger respondents, women, those with higher levels of education, and those with no chronic conditions.

Conclusions

Although compared with the general population, health-related internet use statistics are lower, our results show that the idea of involving homeless populations in the digital health ecosystem is viable, especially if barriers to access are systematically reduced. The results show that digital health services have great promise as another tool in the hands of community shelters for keeping homeless populations well ingrained in the social infrastructure as well as for disease prevention purposes.

Homelessness and the use of Emergency Department as a source of healthcare: a systematic review

BACKGROUND

Persons experiencing homelessness (PEH) often use hospital Emergency Department (ED) as the only source of healthcare. The aim of this study was to undertake a systematic review to identify the prevalence, clinical reasons and outcomes in relation to ED visits by PEH.

METHODS

A protocol-led (CRD42020189263) systematic review was conducted using search of MEDLINE, EMBASE, CINAHL and Google Scholar databases. Studies that reported either the prevalence of homelessness in the ED or clinical reasons for presentation to ED by PEH and published in English language were included. Definitions of homelessness used by study authors were accepted.

RESULTS

From the screening of 1349 unique titles, a total of 36 studies were included. Wide variations in the prevalence and key cause of presentations were identified across the studies often linked to differences in country, study setting, disease classification and data collection methods. The proportion of ED visits contributed by PEH ranged from 0.41 to 19.6%. PEH made an average of 0.72 visits to 5.8 visits per person per year in the ED [rate ratio compared to non-homeless 1.63 to 18.75]. Up to a third and quarter of the visits were contributed by alcohol-related diagnoses and substance poisoning respectively. The percentage of PEH who died in the ED ranged from 0.1 to 0.5%.

CONCLUSIONS

Drug-, alcohol- and injury-related presentations dominate the ED visits by PEH. Wide variations in the data were observed in regard to attendance and treatment outcomes. There is a need for prevention actions in the community, integrated discharge and referral pathways between health, housing and social care to minimise frequent usage and improve attendance outcomes.

Access to healthcare for people experiencing homelessness in the UK and Ireland: a scoping review

BACKGROUND

People experiencing homelessness (PEH) have poorer physical and mental health than the general population. They are also more likely to have less access to healthcare. These processes of access can be better understood using Levesque's access framework which addresses both supply (service provision) and demand (user abilities).

METHODS

Following the Joanna Briggs Institute (JBI) guidelines, electronic peer-reviewed databases were searched in February 2022 for studies published since 2000 related to access to healthcare for PEH ages 16 and older in the United Kingdom (UK) and Ireland. Retrieved articles were screened and those eligible were selected for data extraction. Qualitative and quantitative studies were included.

RESULTS

Fifty-six papers out of 538 identified were selected and aliased. Six main themes were identified: staff education, flexibility of systems, service coordination, patient preparedness, complex health needs and holistic care. These relate to the Levesque access framework.

CONCLUSIONS

Improving access to healthcare for PEH requires changes to how services are provided and how service-user abilities are supported.

A Scoping Review of the Health Impact of the COVID-19 Pandemic on Persons Experiencing Homelessness in North America and Europe

Persons experiencing homelessness (PEH) are at heightened risk for infection, morbidity, and mortality from COVID-19. However, health consequences of the pandemic extend far beyond those directly caused by the virus. This scoping review aimed to explore the impacts of the COVID-19 pandemic on the health and well-being of PEH in North America and Europe. A systematic search of academic and grey literature was conducted in September 2021. To be included, studies had to include primary data related to the impact of the pandemic on health or well-being of PEH and be written in English. All potentially relevant references were independently screened by two reviewers, and minor conflicts were settled with input of a third reviewer. A total of 96 articles met criteria for inclusion. Data extraction was completed for all included studies, and findings synthesised and presented thematically. Numerous health impacts of the pandemic on PEH were identified, including SARS-CoV-2 infection, morbidity, mortality, and hospitalisation, fear of infection, access to housing, hygiene, PPE, food, as well as mental health, substance use, other health-related outcomes and treatment services. Gaps in the literature relating to persons using alcohol, access to mental health support, and violence were also identified. Implications for future research are discussed.

Real-world evidence of sofosbuvir/velpatasvir as an effective and simple hepatitis C virus treatment and elimination tool in homeless populations

Background: People experiencing homelessness are disproportionately affected by hepatitis C virus (HCV) and can face specific barriers to care. Simple treatment algorithms could increase linkage to care in this population. Methods: This retrospective real-world analysis pooling data from 15 clinical cohorts evaluated effectiveness of a once-daily sofosbuvir/velpatasvir (SOF/VEL) regimen in HCV-infected people experiencing homelessness. The primary outcome was sustained virological response (SVR) in the effectiveness population (patients with confirmed SVR status). Secondary outcomes included reasons for not achieving SVR, adherence and time between diagnosis and SOF/VEL treatment start. Results: Of 153 patients treated with SOF/VEL for 12 weeks without ribavirin, SVR was 100% in the effectiveness population (n = 122), irrespective of various baseline factors including active injecting drug use and presence of mental health disorders. Conclusion: HCV-infected people experiencing homelessness can successfully be treated with SOF/VEL. SOF/VEL enables implementation of simple treatment algorithms and can support test-and-treat strategies through rapid treatment starts and minimal monitoring.

Capturing learning from public involvement with people experiencing homelessness to help shape new physiotherapy research: Utilizing a reflective model with an under-served, vulnerable population

Introduction

People experiencing homelessness (PEH) have poorer health than housed people but face barriers accessing care and being involved in research. As an often‐ignored group, their contribution to help shape research that is for and about them is essential, as it can strengthen the research proposal, in turn facilitating research and outcomes that are relevant to this vulnerable group.

Methods

Six people with experience of homelessness attended a PPI consultation aided by Pathway, a UK homeless peer advocacy charity, which coordinates an ‘Experts by Experience’ group. We present reflections on conducting PPI with PEH that informed the development of a physiotherapy research proposal. Kolb's Experiential Learning Cycle guided reflections across four stages: (1) describing the PPI experience; (2) reviewing and reflecting on the PPI experience; (3) learning from the PPI experience; and (4) planning and trying out learning.

Results

Reflections highlighted the importance of: working closely with an advocacy organisation and leader to reach under‐served people; the diversity of experiences; using familiar venues, contingency and budget planning; flexibility and ‘allowing time; talking less; listening more’; planning for early and ongoing PPI, and the potential of mobile ‘one‐off’ PPI outreach models to reach vulnerable groups.

Conclusion

Kolb's Experiential Learning Cycle aided team reflection on feedback from PEH, which helped refine and strengthen a physiotherapy research proposal. The project was unfunded. However, a reflective model helped maximize learning and impact including for future PPI and research. The novel application of Kolb's Experiential Learning Cycle provided structure, facilitated reflection and enhanced individual and collective learning and may benefit capturing learning from PPI with other vulnerable populations.

Patient or Public Contribution

We highlight how a PPI consultation with people with experience of homelessness helped shape a funding proposal. Additionally, the reflections of the experts by experience team leader are included.

Representation of persons experiencing homelessness and coding of homelessness in general practices: descriptive evaluation using healthcare utilisation data

Background

Epidemiological studies focused on primary healthcare needs of persons experiencing homelessness (PEH) are often based on data from specialist homeless healthcare services.

Aim

To explore the presentation of PEH, coding of homelessness, and associated health conditions in mainstream primary care general practices in England.

Design & setting

EMIS electronic database search of medical records was conducted across 48 general practices in a clinical commissioning group (CCG), representing one of the most socioeconomically deprived regions in England, which also lacks a specialist primary healthcare service for PEH.

Method

Key terms and codes were used to identify PEH, their respective diagnoses across 22 health conditions, and prescribed medications over the past 4 years.

Results

From a population of approximately 321 000, 43 (0.013%) people were coded as PEH, compared with a homelessness prevalence of 0.5% in the English general population. Mental health conditions were the most prevalent diagnoses among the PEH registrants (56.6%); the recorded prevalence of other common long-term conditions in PEH was lower than the levels observed in PEH registered with specialist homelessness health services.

Conclusion

In a population with approximately four times higher rate of statutory homelessness, PEH representation in mainstream general practices was under-represented by several folds. As homelessness overlaps with mental health, substance misuse, and long-term health conditions, consistent coding of homelessness in medical records is imperative in order to offer tailored support and prevention actions when patients present for services.

Clinical characteristics, attendance outcomes and deaths of homeless persons in the emergency department: implications for primary health care and community prevention programmes

OBJECTIVES

Persons experiencing homelessness (PEH) are known to be often excluded from primary health care and community prevention programmes leading to high use of hospital emergency departments (EDs). This study aimed to identify demographic features, clinical characteristics and attendance outcomes of PEH presenting to ED.

STUDY DESIGN

Analysis of routinely collected data set.

METHODS

Clinical presentations and drug prescription data of PEH who presented a major ED in the West Midlands region of England from 2014 to 2019 were extracted and analysed using descriptive and inferential statistics.

RESULTS

During the study period, 3271 of 596,198 presentations were made by PEH; 74% PEH attendees were male. Drug- and alcohol-related conditions, as well as pain and injury constituted the most frequent reasons for presentation, contributing to over half of all presentations. A significantly higher proportion of males (n = 481, 20.3%) presented with drug and alcohol problems than females (n = 93, 11.2%) (P ≤ 0.001). However, pain was the primary reason for presentation for twice as many female patients (n = 189, 22.8%) compared with males (n = 305, 12.9%) (P < 0.001). Nearly one in five left the ED before being assessed and a total of 39 patients (1.2%) died in the ED and 785 (24.0%) required in-patient admissions to the same hospital.

CONCLUSIONS

Drug, alcohol and pain including the need of opioid analgesics constituted the majority of presentations made by PEH in ED. The observed rate of death of PEH in ED is 12 times higher than the general population. A very high proportion of PEH also leave the ED before being treated. Future research should focus on strengthening community interventions, particularly to improve access to those at risk of dual diagnoses of substance misuse and mental health problems. Interventions involving multisector collaborations are needed to improve seamless discharge from ED and minimise repeat attendance. Gender differences in the nature of presentations and ED outcomes needs to be investigated further.

Scope, quality and inclusivity of international clinical guidelines on mental health and substance abuse in relation to dual diagnosis, social and community outcomes: a systematic review

OBJECTIVE

It is estimated that up to 75% of patients with severe mental illness (SMI) also have substance use disorder (SUD). The aim of this systematic review was to explore the scope, quality and inclusivity of international clinical guidelines on mental health and/or substance abuse in relation to diagnosis and treatment of co-existing disorders and considerations for wider social and contextual factors in treatment recommendations.

METHOD

A protocol (PROSPERO CRD42020187094) driven systematic review was conducted. A systematic search was undertaken using six databases including MEDLINE, Cochrane Library, EMBASE, PsychInfo from 2010 till June 2020; and webpages of guideline bodies and professional societies. Guideline quality was assessed based on 'Appraisal of Guidelines for Research & Evaluation II' (AGREE II) tool. Data was extracted using a pre-piloted structured data extraction form and synthesized narratively. Reporting was based on PRISMA guideline.

RESULT

A total of 12,644 records were identified. Of these, 21 guidelines were included in this review. Three of the included guidelines were related to coexisting disorders, 11 related to SMI, and 7 guidelines were related to SUD. Seven (out of 18) single disorder guidelines did not adequately recommend the importance of diagnosis or treatment of concurrent disorders despite their high co-prevalence. The majority of the guidelines (n = 15) lacked recommendations for medicines optimisation in accordance with concurrent disorders (SMI or SUD) such as in the context of drug interactions. Social cause and consequence of dual diagnosis such as homelessness and safeguarding and associated referral pathways were sparsely mentioned.

CONCLUSION

Despite very high co-prevalence, clinical guidelines for SUD or SMI tend to have limited considerations for coexisting disorders in diagnosis, treatment and management. There is a need to improve the scope, quality and inclusivity of guidelines to offer person-centred and integrated care.

Barriers to monitoring and management of cardiovascular and metabolic health of patients prescribed antipsychotic drugs: a systematic review

BACKGROUND

The use of atypical antipsychotics which currently form the primary choice pharmacotherapy for several mental health conditions have been linked to cardiovascular and metabolic side effects. This systematic review aimed to investigate the barriers to monitoring and management of cardiovascular co-morbidities in patients prescribed antipsychotic medicines.

METHODS

A protocol-led (CRD-42018106002) systematic literature review was conducted by searching Medline, Embase, and PsycINFO databases 2003 until October 2019. Cochrane, Centre for Review and Dissemination (CRD) and PRISMA guidelines were followed. Studies investigating barriers to monitoring and management of cardiovascular co-morbidities in patients prescribed antipsychotic medicines were included.

RESULTS

A total of 23 records were included. Key barriers included a) health-care system-related factors such as lack of knowledge and expertise amongst care providers, available resources, confusion around remit and roles, fragmentation of care such as across general practitioners and psychiatrists, and time constraints and b) patient-related factors such as disability resulting from mental health conditions, knowledge and skills of the patients.

CONCLUSION

Barriers to monitoring and management of cardiovascular and metabolic health of patients taking antipsychotic medicines are multidimensional. Apart from educational interventions directed to both patients and health-care professionals, the results suggest a need for the improvement of wider system-related factors to improve physical health of patients prescribed antipsychotic medicines. Clearer guidelines, clarity of remit and roles amongst service providers are necessary in addition to educational interventions directed at patients and health-care professionals in improving physical health monitoring, counselling and management of patients prescribed antipsychotic medicines.

TRIAL REGISTRATION

A protocol was developed and registered with PROSPERO as per PRISMA-P guidelines ( CRD 42018106002 ).
