Morbidity and mortality in homeless individuals, prisoners, sex workers, and individuals with substance use disorders in high-income countries: a systematic review and meta-analysis

Inclusion oral health: Advancing a theoretical framework for policy, research and practice

In response to headlines about the oral health of persons experiencing social exclusion resonating in high-income countries, and research demonstrating the need for urgent action, a symposium entitled 'International Perspectives on Socially Inclusive Dentistry: A Call to Action' was organized for the IADR International Meeting of 2018. The aim of the symposium was to initiate an international dialogue on barriers to care, multidisciplinary action and examples of best practice for service delivery for people experiencing social exclusion; in other words, to develop the idea of inclusion oral health. Through our international exchange, what emerged was an awareness of a lack of professional consensus: What exactly is inclusion oral health? A theoretical framework to push forward the policy, research and practice agenda was clearly needed. This paper advances such a framework. Over the decades, dentistry has forged an approach to service delivery mainly through a business, demand-led model. While oral health continues to improve globally, an important consequence of this approach is that it compounds the social exclusion that many people are already experiencing because of a constellation of economic, political, cultural and individual factors. Thus, many people are simply not getting the dental care they need. In contrast, drawing on the theoretical literature on social exclusion, intersectionality and othering, we suggest that dentistry could act as an agent for social inclusion as a more responsive, all-encompassing form of oral health care and delivery. This paper advances a theoretical framework for inclusion oral health, and an action plan to show how inclusion oral health may become one solution in an armamentarium to tackle the global phenomena of oral health inequities.

Individual-Level Predictors for Becoming Homeless and Exiting Homelessness: a Systematic Review and Meta-analysis

Homelessness remains a societal problem. Compiled evidence of predictors for becoming homeless and exiting homelessness might be used to inform policy-makers and practitioners in their work to reduce homeless-related problems. We examined individual-level predictors for becoming homeless and exiting homelessness by searching PubMed, EMBASE, PsycINFO, and Web of Science up to January 2018. Becoming homeless and exiting homelessness were the outcomes. Observational studies with comparison groups from high-income countries were included. The Newcastle Ottawa Quality Assessment Scale was used for bias assessment. Random effects models were used to calculate pooled odds ratios (ORs) with 95% confidence intervals (CIs). We included 116 independent studies of risk factors for becoming homeless and 18 for exiting homelessness. We found evidence of adverse life events as risk factors for homelessness, e.g., physical abuse (OR 2.9, 95% CI 1.8-4.4) and foster care experiences (3.7, 1.9-7.3). History of incarceration (3.6, 1.3-10.4), suicide attempt (3.6, 2.1-6.3), and psychiatric problems, especially drug use problems (2.9, 1.5-5.1), were associated with increased risk of homelessness. The heterogeneity was substantial in most analyses (I² > 90%). Female sex (1.5, 1.1-1.9; I² = 69%) and having a partner (1.7, 1.3-2.1; I² = 40%) predicted higher chances whereas relationship problems (0.6, 0.5-0.8), psychotic disorders (0.4, 0.2-0.8; I² = 0%), and drug use problems (0.7, 0.6-0.9; I² = 0%) reduced the chances for exiting homelessness. In conclusion, sociodemographic factors, adverse life events, criminal behaviour, and psychiatric problems were individual-level predictors for becoming homeless and/or exiting homelessness. Focus on individual-level vulnerabilities and early intervention is needed. PROSPERO registration number: CRD42014013119 .

Social and structural factors associated with substance use within the support network of adults living in precarious housing in a socially marginalized neighborhood of Vancouver, Canada

BACKGROUND

The structure of a social network as well as peer behaviours are thought to affect personal substance use. Where substance use may create health risks, understanding the contribution of social networks to substance use may be valuable for the design and implementation of harm reduction or other interventions. We examined the social support network of people living in precarious housing in a socially marginalized neighborhood of Vancouver, and analysed associations between social network structure, personal substance use, and supporters' substance use.

METHODS

An ongoing, longitudinal study recruited 246 participants from four single room occupancy hotels, with 201 providing social network information aligned with a 6-month observation period. Use of tobacco, alcohol, cannabis, cocaine (crack and powder), methamphetamine, and heroin was recorded at monthly visits. Ego- and graph-level measures were calculated; the dispersion and prevalence of substances in the network was described. Logistic mixed effects models were used to estimate the association between ego substance use and peer substance use. Permutation analysis was done to test for randomness of substance use dispersion on the social network.

RESULTS

The network topology corresponded to residence (Hotel) with two clusters differing in demographic characteristics (Cluster 1 -Hotel A: 94% of members, Cluster 2 -Hotel B: 95% of members). Dispersion of substance use across the network demonstrated differences according to network topology and specific substance. Methamphetamine use (overall 12%) was almost entirely limited to Cluster 1, and absent from Cluster 2. Different patterns were observed for other substances. Overall, ego substance use did not differ over the six-month period of observation. Ego heroin, cannabis, or crack cocaine use was associated with alter use of the same substances. Ego methamphetamine, powder cocaine, or alcohol use was not associated with alter use, with the exception for methamphetamine in a densely using part of the network. For alters using multiple substances, cannabis use was associated with lower ego heroin use, and lower ego crack cocaine use. Permutation analysis also provided evidence that dispersion of substance use, and the association between ego and alter use was not random for all substances.

CONCLUSIONS

In a socially marginalized neighborhood, social network topology was strongly influenced by residence, and in turn was associated with type(s) of substance use. Associations between personal use and supporter's use of a substance differed across substances. These complex associations may merit consideration in the design of interventions to reduce risk and harms associated with substance use in people living in precarious housing.

An ethical exploration of the narratives surrounding substance use and pain management at the end of life: a discussion paper

This discussion article examines narrative positioning related to pain management for people who use substances at the end of life. We explore how dominant narrative genres associated with biomedicine, such as ‘restitution’ and narratives common within the context of drug services such as ‘recovery’ can hinder effective pain management within this population. We argue that these discourses can marginalise the ethical self-identity of patients who use substances at the end of life. It can also trouble health and social care professionals in supporting patients and generating counter-narratives that challenge those often associated with substance use. Stigma is a common experience for this population with stereotyping as ‘junkies’ and associated with criminality. They are positioned as drug-seeking, and this requires more surveillance at the end of life when opioid therapy is potentially more available and authorised. This can make it challenging to generate ‘companion’ stories that are positive and maintain moral adequacy. Dominant biomedical narrative genres often prevent the recognition of the fractured stories that people using substances can often present with. This can lead to narrative silencing and to the under treatment of pain. The person’s self-identity is invested in narratives of recovery, and opioid use symbolises their addicted past because for practitioners, this population is at clinical risk with the potential for drug seeking behaviours. Whilst not requiring formal ethical review this discussion paper was constructed in accordance with good scientific practice with the work of other researchers respected and cited appropriately.

Competing priorities and second chances - A qualitative exploration of prisoners' journeys through the Hepatitis C continuum of care

High levels of undiagnosed and untreated HCV infection exist in prison populations globally. Prisons are a key location to identify, treat and prevent HCV infection among people who inject drugs (PWID). Understanding prisoners’ lived experiences of the HCV continuum of care informs how HCV care can be effectively delivered to this marginalised and high-risk population. This study aimed to explore Irish prisoners’ experience of prison and community-based HCV care. We conducted one-to-one interviews with 25 male prisoners with chronic HCV infection. Data collection and analysis was informed by grounded theory. The mean age of participants and first incarceration was 39.5 and 18.3 years respectively. The mean number of incarcerations was eight. The following themes were identified: medical and social factors influencing engagement (fear of treatment and lack of knowledge, HCV relevance and competing priorities), adverse impact of HCV on health and wellness, positive experience of prison life and health care and the transformative clinical and non-clinical changes associated with HCV treatment and cure. Findings suggest that prison release was associated with multiple stressors including homelessness and drug dependence which quickly eroded the health benefits gained during incarceration. The study generated a substantive theory of the need to increase the importance of HCV care among the routine competing priorities associated with the lives of PWID. HCV infected prisoners often lead complex lives and understanding their journeys through the HCV continuum can inform the development of meaningful HCV care pathways. Many challenges exist to optimising HCV treatment uptake in this group and incarceration is an opportunity to successfully engage HCV infected prisoners who underutilise and are underserved by community-based medical services. Support and linkage to care on release is essential to optimising HCV management.

Addressing complex societal challenges in health education – A physiotherapy-led initiative embedding inclusion health in an undergraduate curriculum

Socially marginalised groups suffer vastly poorer health outcomes compared to the general population. Inclusion health seeks to directly address the health inequities experienced by groups such as homeless people and refugees. Despite the unique healthcare needs experienced by these vulnerable groups, inclusion health features very little in health education curricula. This letter has been written by a group of clinicians, academics, clinical education specialists and students with a common interest in inclusion health. In the absence of established guidance on how best to incorporate the broad topic of inclusion health in undergraduate education, we have developed a two-pronged approach within physiotherapy. We are writing to highlight the following initiatives; firstly, the provision of a dedicated undergraduate clinical placement devoted to the area of inclusion health. Secondly, we have also initiated a step-wise process of introducing the topic of inclusion health into the formal undergraduate curriculum. This letter demonstrates the need to implement strategies to incorporate inclusion health into the curriculum and the approaches described are applicable to diverse health professions and settings.

End of life care for people with alcohol and drug problems: Findings from a Rapid Evidence Assessment

People who use alcohol and other drugs(hereafter "substances") and who are over the age of 40 are now more likely to die of a non-drug related cause than people who use substances under the age of 40. This population will therefore potentially need greater access to palliative and end of life care services. Initially, the purpose of this rapid evidence assessment (REA), conducted August 2016-August 2017, was to explore the peer-reviewed evidence base in relation to end of life care for people with problematic substance use. The following databases were searched using date parameters of 1 January 2004-1 August 2016: Amed, Psycharticles, Ovid, Ageinfo, Medline, Ebscohost, ASSIA, Social Care Online, Web of Knowledge, Web of Science, SSCI, Samsha, NIAAA. Data were extracted using a predefined protocol incorporating inclusion and exclusion criteria. Given the dearth of evidence emerging on interventions and practice responses to problematic substance use, the inclusion criteria were broadened to include any peer-reviewed literature focussing on substance use specifically and end of life care. There were 60 papers that met the inclusion criteria. These were quality assessed. Using a textual thematic approach to categorise findings, papers fell into three broad groups (a) pain management, (b) homeless and marginalised groups, and (c) alcohol-related papers. In general, this small and diverse literature lacked depth and quality. The papers suggest there are challenges for health and social care professionals in meeting the end of life needs of people who use substances. Addressing issues like safe prescribing for pain management becomes more challenging in the presence of substance use and requires flexible service provision from both alcohol/drug services and end of life care providers. Work is needed to develop models of good practice in working with co-existing substance use and end of life conditions as well as prevalence studies to provide a wider context for policy development.

"A Mile in Her Shoes": A qualitative exploration of the perceived benefits of volunteer led running groups for homeless women

"A Mile in Her Shoes" is a volunteer-led charity which provides running groups for homeless women. The objective of this study was to explore the experiences of homeless women attending these running groups and to establish how participation in a supported running group impacted their lives. This exploratory qualitative study was carried out across two sites in London UK during February and April 2017. All regular attenders of the running groups were invited to participate in the study; subsequently, a self-selected sample of 11 women consented to being interviewed. Data were collected by female interviewers on a one-to-one basis, steered by a semi-structured topic guide. All interviews were digitally recorded, transcribed verbatim, and analysed using thematic analysis. Themes were cross-referenced by the research team and findings were supported by direct quotes. Five main themes emerged from the findings: the positive impact of the charity; homeless women's motivations and barriers to participating in running groups; the benefits of participating on physical and mental health; the importance and value of social support from the group; and the value of being provided with quality running kit. This study concludes that volunteer-led running groups are valued by homeless women by helping them take control of their health. It provides insight into their engagement in physical activity, thus potentially helping prevent injury or illness, and aiding recovery and rehabilitation. One implication of this study is that gathering homeless women's views helps to steer how community-based physical activity programmes can benefit their wellbeing. However, this small-scale study may have limited generalisability, with the topic warranting further research.

Housing First: Unsuppressed Viral Load Among Women Living with HIV in San Francisco

While poverty is an established barrier to achieving success at each step of the HIV care continuum, less is known about specific aspects of poverty and how they overlap with behavior in exceptionally low-income individuals who live in well-resourced areas. We considered unsuppressed viral load over 3 years among women living with HIV in San Francisco who used homeless shelters, low-income hotels and free meal programs. One-hundred twenty study participants were followed; 60% had > 1 unsuppressed viral load and 19% were unsuppressed at every visit. Across six-month intervals, the odds of unsuppressed viral load were 11% higher for every 10 nights spent sleeping on the street [Adjusted Odds Ratio (AOR) 1.11, 95% CI 1.02-1.20]; 16% higher for every 10 nights spent sleeping in a shelter (AOR/10 nights 1.16, 95% CI 1.06-1.27); 4% higher for every 10 nights spent sleeping in a single-room occupancy hotel (AOR/10 nights 1.04, 95% CI 1.02-1.07); and over threefold higher among women who experienced any recent incarceration (AOR 3.56, 95% CI 1.84-6.86). Violence and recent use of outpatient health care did not significantly predict viral suppression in adjusted analysis. While strategies to promote retention in care are important for vulnerable persons living with HIV, they are insufficient to ensure sustained viral suppression in low-income women experiencing homelessness and incarceration. Results presented here in combination with prior research linking incarceration to homelessness among women indicate that tailored interventions, which not only consider but prioritize affordable housing, are critical to achieving sustained viral suppression in low-income women living with HIV.

The Milwaukee Continuum: Older Veterans and Nonveterans Use Housing First to Exit Homelessness

Background: Homelessness is about survival and more than an issue of bricks and mortar. It is not a static dimension and alludes to a troubled age and brokenness of society. Despite dramatic declines in numbers of people presently homeless, the issue continues to be a public health issue. The number of veterans currently homeless continues to be of national concern despite application of resources. More needs to be done to better understand the concerns of veterans, once homeless and now housed. Method: Qualitative research in the form of interviews provided insights from the veterans on their experience around achieving housing. Qualitative methods are often used in evaluations as they speak of the experience of the program being evaluated by capturing and then communicating the narratives of the participants. This study was grounded in community-based participatory research where a member of community was a part of all phases of the research process. Results: Seven interviews with formerly homeless veterans were conducted. Themes included the following: Burnt Brides and Regrets, Survival, Spirituality, Recovery and Stress, Supportive Care, Reunite Family, and Sickness and Health. Discussion: The themes provide insight into the experience of the veterans and a means to better understand the healing process. Understanding of the healing process includes the following: Acknowledging the Courage to go Deep, Time, Veterans Giving Back, and Recovery is Ongoing. Despite what was learned, further research is needed to better understand the long-term implications of people formerly homeless now housed.

Hepatitis C virus testing, liver disease assessment and direct-acting antiviral treatment uptake and outcomes in a service for people who are homeless in Sydney, Australia: The LiveRLife homelessness study

People who are homeless have increased hepatitis C virus (HCV) infection risk, and are less likely to access primary healthcare. We aimed to evaluate HCV RNA prevalence, liver disease burden, linkage to care and treatment uptake and outcomes among people attending a homelessness service in Sydney. Participants were enrolled in an observational cohort study with recruitment at a homelessness service over eight liver health campaign days. Finger-stick whole-blood samples for Xpert® HCV Viral Load and venepuncture blood samples were collected. Participants completed a self-administered survey and received transient elastography and clinical assessment by a general practitioner or nurse. Clinical follow-up was recommended 2-12 weeks after enrolment. For participants initiating direct-acting antiviral (DAA) therapy, medical records were audited retrospectively and treatment outcome data were collected. Among 202 participants (mean age, 48 years), 82% were male (n = 165), 39% (n = 78) reported ever injecting drugs, of whom 63% (n = 49) injected in the previous month. Overall, 23% (n = 47) had detectable HCV RNA and 6% (n=12) had cirrhosis. HCV RNA prevalence among participants with either injecting or incarceration history was 35% (37/105), compared to 4% (3/73) among participants without these risk factors. Among those with detectable HCV RNA, 23 (49%) commenced therapy, of whom 65% (n = 15) achieved sustained virological response, while the remainder had no available treatment outcome. No participant had documented virological failure. HCV DAA treatment uptake among people attending a homelessness service was encouraging, but innovative models of HCV care are required to improve linkage to care and treatment uptake among this highly marginalized population.

Health assessments and screening tools for adults experiencing homelessness: a systematic review

BACKGROUND

Homelessness is increasing globally. It results in poorer physical and mental health than age matched people living in permanent housing. Better information on the health needs of people experiencing homelessness is needed to inform effective resourcing, planning and service delivery by government and care organisations. The aim of this review was to identify assessment tools that are valid, reliable and appropriate to measure the health status of people who are homeless.

METHODS

Data sources: A systematic literature search was conducted in PubMed (and Medline), PsychInfo, Scopus, CINAHL and ERIC from database inception until September 2018. Key words used were homeless, homelessness, homeless persons, vagrancy, health status, health, health issues, health assessment and health screening. The protocol was registered with PROSPERO. The National Health and Medical Research Council of Australia (NHMRC) hierarchy of evidence was applied; methodological quality of included articles was assessed using the McMaster critical appraisal tools and psychometric properties of the tools were appraised using the International Centre for Allied Health Evidence Ready Reckoner.

RESULTS

Diverse tools and measures (N = 71) were administered within, and across the reviewed studies (N = 37), with the main focus being on general health, oral health and nutrition. Eleven assessment tools in 13 studies had evidence of appropriate psychometric testing for the target population in domains of quality of life and health status, injury, substance use, mental health, psychological and cognitive function. Methodological quality of articles and tools were assessed as moderate to good. No validated tools were identified to assess oral health, chronic conditions, anthropometry, demography, nutrition, continence, functional decline and frailty, or vision and hearing. However, assessments of physical constructs (such as oral health, anthropometry, vision and hearing) could be applied to homeless people on a presumption of validity, because the constructs would be measured with clinical indicators in the same manner as people living in permanent dwellings.

CONCLUSIONS

This review highlighted the need to develop consistent and comprehensive health assessment tools validated with, and tailored for, adults experiencing homelessness.

Making sense of street chaos: an ethnographic exploration of homeless people's health service utilization

Background

Homeless people have poor health and mortality indices. Despite this they make poor usage of health services. This study sought to understand why they use health services differently from the domiciled population.

Methods

Ethnographic observations were conducted at several homeless services, in Dublin. This was supplemented with 47 semi-structured interviews with homeless people and two focus groups of homeless people and hospital doctors. A critical-realist approach was adopted for interpretation of the data.

Results

Homeless people tended to present late in their illness; default early from treatment; have low usage of primary-care, preventative and outpatient services; have high usage of Emergency and Inpatient services; and poor compliance with medication. They tended to avoid psychiatric services. A number of external barriers were identified. These were classified as physical (distance) administrative (application process for medical care; appointments; queues; the management of addiction in hospital; rules of service; and information providing processes); and attitudinal (stigma; differing attitudes as to appropriate use of services. A new form of barrier, Conversations of Exclusion was identified and described. Internalised barriers were identified which were in nature, either cognitive (fatalistic, denial, deferral to future, presumption of poor treatment or discrimination, self blame and survival cognitions) or emotional (fear; embarrassment, hopelessness and poor self-esteem). Generative mechanisms for these factors were identified which either affected participants prior to homelessness (marginalization causing hopelessness, familial dysfunction, substance misuse, fear of authority, illiteracy; mental health; and poor English) or after becoming homeless (homelessness; ubiquity of premature death; substance misuse; prioritization of survival over health; threat of violence; chaotic nature of homelessness; negative experiences of authority; and stigma.

Conclusions

An explanatory critical realist model integrating the identified generative mechanisms, external and internalised barriers was developed to explain why the Health service Utilization of homeless people differs from the domiciled populations. This new model has implications for health service policy makers and providers in how they design and deliver accessible health services to homeless people.

Oral diseases: a global public health challenge

Oral diseases are among the most prevalent diseases globally and have serious health and economic burdens, greatly reducing quality of life for those affected. The most prevalent and consequential oral diseases globally are dental caries (tooth decay), periodontal disease, tooth loss, and cancers of the lips and oral cavity. In this first of two papers in a Series on oral health, we describe the scope of the global oral disease epidemic, its origins in terms of social and commercial determinants, and its costs in terms of population wellbeing and societal impact. Although oral diseases are largely preventable, they persist with high prevalence, reflecting widespread social and economic inequalities and inadequate funding for prevention and treatment, particularly in low-income and middle-income countries (LMICs). As with most non-communicable diseases (NCDs), oral conditions are chronic and strongly socially patterned. Children living in poverty, socially marginalised groups, and older people are the most affected by oral diseases, and have poor access to dental care. In many LMICs, oral diseases remain largely untreated because the treatment costs exceed available resources. The personal consequences of chronic untreated oral diseases are often severe and can include unremitting pain, sepsis, reduced quality of life, lost school days, disruption to family life, and decreased work productivity. The costs of treating oral diseases impose large economic burdens to families and health-care systems. Oral diseases are undoubtedly a global public health problem, with particular concern over their rising prevalence in many LMICs linked to wider social, economic, and commercial changes. By describing the extent and consequences of oral diseases, their social and commercial determinants, and their ongoing neglect in global health policy, we aim to highlight the urgent need to address oral diseases among other NCDs as a global health priority.

Provision and accessibility of primary healthcare services for people who are homeless: a qualitative study of patient perspectives in the UK

BACKGROUND

Anecdotal reports of people who are homeless being denied access and facing negative experiences of primary health care have often emerged. However, there is a dearth of research exploring this population's views and experiences of such services.

AIM

To explore the perspectives of individuals who are homeless on the provision and accessibility of primary healthcare services.

DESIGN AND SETTING

A qualitative study with individuals who are homeless recruited from three homeless shelters and a specialist primary healthcare centre for the homeless in the West Midlands, England.

METHOD

Semi-structured interviews were audiorecorded, transcribed verbatim, and analysed using a thematic framework approach. The Theoretical Domains Framework (TDF) was used to map the identified barriers in framework analysis.

RESULTS

A total of 22 people who were homeless were recruited. Although some participants described facing no barriers, accounts of being denied registration at general practices and being discharged from hospital onto the streets with no access or referral to primary care providers were described. Services offering support to those with substance misuse issues and mental health problems were deemed to be excluding those with the greatest need. A participant described committing crimes with the intention of going to prison to access health care. High satisfaction was expressed by participants about their experiences at the specialist primary healthcare centre for people who are homeless (SPHCPH).

CONCLUSION

Participants perceived inequality in access, and mostly faced negative experiences, in their use of mainstream services. Changes are imperative to facilitate access to primary health care, improve patient experiences of mainstream services, and to share best practices identified by participants at the SPHCPH.

Using Always Events to derive patient-centred quality improvement priorities in a specialist primary care service providing care to a homeless population

Background

‘Always Events’ (AE) is a validated quality improvement (QI) method where patients, and/or carers, are asked what is so important that it should ‘always’ happen when they interact with healthcare services. Answers that meet defined criteria can be used to direct patient-centred QI activities. This method has never, to our knowledge, been applied in the care of a UK homeless population. We aimed to test the aspects of the acceptability and feasibility of the AE method to inform on its potential application to improve care for this vulnerable group of patients.

Methods

All patients attending three consecutive drop-in clinics at a specialist homeless general practitioner service in Glasgow, who agreed to participate, were interviewed. Anonymised responses were transcribed and coded and a thematic analysis performed. Themes were summarised to generate candidate AE using the patient’s own words. The authors then determined if they met the AE criteria.

Results

Twenty out of 22 eligible patients were interviewed. Oral transcribing was found to be an acceptable way to gather data in this group. Nine candidate AEs were generated, of which five fitted the criteria to be used as metrics for future QI projects. This project generated AEs and QI targets, and highlighted issues of importance to patients that could be easily addressed.

Conclusion

In the homeless context, obtaining high engagement and useful patient feedback, in a convenient way, is difficult. The AE method is an acceptable and feasible tool for generating QI targets that can lead to improvements in care for this vulnerable group.

Our data, our society, our health: A vision for inclusive and transparent health data science in the United Kingdom and beyond

The last 6 years have seen sustained investment in health data science in the United Kingdom and beyond, which should result in a data science community that is inclusive of all stakeholders, working together to use data to benefit society through the improvement of public health and well-being. However, opportunities made possible through the innovative use of data are still not being fully realised, resulting in research inefficiencies and avoidable health harms. In this paper, we identify the most important barriers to achieving higher productivity in health data science. We then draw on previous research, domain expertise, and theory to outline how to go about overcoming these barriers, applying our core values of inclusivity and transparency. We believe a step change can be achieved through meaningful stakeholder involvement at every stage of research planning, design, and execution and team-based data science, as well as harnessing novel and secure data technologies. Applying these values to health data science will safeguard a social licence for health data research and ensure transparent and secure data usage for public benefit.

Multimorbidity and emergency department visits by a homeless population: a database study in specialist general practice

BACKGROUND

Estimating healthcare needs of the homeless is associated with challenges in identifying the eligible population.

AIM

To explore the demographic characteristics, disease prevalence, multimorbidity, and emergency department visits of the homeless population.

DESIGN AND SETTING

EMIS electronic database of patient medical records and Quality and Outcomes Framework (QOF) data of all 928 patients registered with a major specialist homeless primary healthcare centre based in the West Midlands in England, from the period of October 2016 to 11 October 2017.

METHOD

Prevalence data on 21 health conditions, multimorbidity, and visits to emergency departments were explored and compared with the general population datasets.

RESULTS

Most homeless people identified were male (89.5%), with a mean age of 38.3 (SD = 11.5) years, and of white British origin (22.1%). Prevalence of substance (13.5%) and alcohol dependence (21.3%), hepatitis C (6.3%), and multimorbidity (21.3%) were markedly higher than in the general population. A third (32.5%) had visited the emergency department in the preceding 12 months. Emergency department visits were associated with a patient history of substance (odds ratio [OR] = 2.69) and alcohol dependence (OR = 3.14).

CONCLUSION

A high prevalence of substance and alcohol dependence, and hepatitis C, exists among the homeless population. Their emergency department visit rate is 60 times that of the general population and the extent of multimorbidity, despite their lower mean age, is comparable with that of 60-69-year-olds in the general population. Because of multimorbidity, homeless people are at risk of fragmentation of care. Diversification of services under one roof, preventive services, and multidisciplinary care are imperative.

How does hard-to-reach status affect antiretroviral therapy adherence in the HIV-infected population? Results from a meta-analysis of observational studies

BACKGROUND

Socially disadvantaged groups, such as drug users, sex workers and homeless individuals, are labelled as "hard-to-reach" (HTR) in public health and medical research. HIV disproportionately impacts these populations, but data on how the HTR status could affect antiretroviral therapy (ART) adherence among HIV-positive people are limited and have not been previously synthesized in a systematic manner. We performed a meta-analysis to explore the association between HTR status and optimal antiretroviral therapy adherence in the HIV-infected population to provide evidence and recommendations regarding ART adherence improvement and HIV infection control and prevention among HTR people.

METHODS

The PubMed, EMBASE, and Cochrance Library databases and the bibliographies of relevant studies were systematically searched up to December 2018. Full-text studies published in English were included, and no geographic or race restrictions were applied. Studies that quantitatively assessed the association between HTR status and optimal ART adherence among HIV-infected populations with a status of homelessness, sex work, or drug use were eligible for inclusion. We estimated the pooled odds ratios (ORs) of HTR characteristics related to ART adherence from each eligible study using a random effects model. The sensitivity, heterogeneity and publication bias were assessed.

RESULTS

Our search identified 593 articles, of which 29 studies were eligible and included in this meta-analysis. The studies were carried out between 1993 and 2017 and reported between 1999 and 2018. The results showed that HTR status resulted in a 45% reduction in the odds of achieving optimal ART adherence compared to odds in the general population (OR = 0.55, 95% confidential intervals (CIs) 0.49-0.62), and this significant inverse association was consistently found regardless of study design, exposure measurement, adherence cut-off points, etc. Subgroup analyses revealed that the HTRs tend to be suboptimal adhering during a longer observational period.

CONCLUSIONS

HIV treatment adherence is extremely negatively affected by HTR status. It is crucial to develop appropriate interventions to improve ART adherence and health outcomes among HTR people who are HIV-infected.

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

Introduction

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

Method

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

Results

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

Conclusions

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

Spatial analysis of cases of Tuberculosis with Mental Disorders in São Paulo

ABSTRACT Objective: To analyze the spatial distribution of Tuberculosis cases with Mental Disorders, identifying factors that determine its occurrence. Method: Ecological study, conducted in the municipalities of São Paulo State. Secondary data were used, with the incidence of Tuberculosis and Mental Disorders as dependent variables in the years 2012 to 2015 and independent variables, socioeconomic, health and income transfer data. The Geographically Weighted Regression was applied in this study. Results: It was observed a distinct distribution between cases of Tuberculosis and Mental Disorders in the municipalities of São Paulo State. Among the explanatory factors, the Primary Care Coverage, population of freedom and income inequality were spatially associated with Mental Illness (R2= 0.12); Alcoholism (R2= 0.12) Illicit Drugs (R2= 0.50) and Smoking (R2= 0.50). Conclusion / Final considerations: The study advances in knowledge by evidencing the spatial distribution of cases of Tuberculosis and Mental Disorders, evidencing the determining factors for its occurrence in São Paulo State.

Homeless health care: meeting the challenges of providing primary care

People experiencing homelessness have multiple complex health conditions yet are typically disengaged from primary health care services and place a significant burden on the acute health system. Barriers preventing people who are homeless from accessing primary care can be both personal and practical and include competing needs and priorities, illness and poor health, physical access to health services, difficulty in contacting services, medication security, and the affordability of health care. Differences in social status and perceptions of being judged can lead to relationship barriers to accessing primary care. Key solutions include prioritising access to stable housing, continuity of health care, specialised homeless general practice, hospital inreach, discharge planning and coordinated care, general practice outreach, and medical recovery centres.

Effects of Housing First approaches on health and well-being of adults who are homeless or at risk of homelessness: systematic review and meta-analysis of randomised controlled trials

BACKGROUND

Homelessness is associated with poor health. A policy approach aiming to end homelessness across Europe and North America, the 'Housing First' (HF) model, provides rapid housing, not conditional on abstinence from substance use. We aimed to systematically review the evidence from randomised controlled trials for the effects of HF on health and well-being.

METHODS

We searched seven databases for randomised controlled trials of interventions providing rapid access to non-abstinence-contingent, permanent housing. We extracted data on the following outcomes: mental health; self-reported health and quality of life; substance use; non-routine use of healthcare services; housing stability. We assessed risk of bias and calculated standardised effect sizes.

RESULTS

We included four studies, all with 'high' risk of bias. The impact of HF on most short-term health outcomes was imprecisely estimated, with varying effect directions. No clear difference in substance use was seen. Intervention groups experienced fewer emergency department visits (incidence rate ratio (IRR)=0.63; 95% CI 0.48 to 0.82), fewer hospitalisations (IRR=0.76; 95% CI 0.70 to 0.83) and less time spent hospitalised (standardised mean difference (SMD)=-0.14; 95% CI -0.41 to 0.14) than control groups. In all studies intervention participants spent more days housed (SMD=1.24; 95% CI 0.86 to 1.62) and were more likely to be housed at 18-24 months (risk ratio=2.46; 95% CI 1.58 to 3.84).

CONCLUSION

HF approaches successfully improve housing stability and may improve some aspects of health. Implementation of HF would likely reduce homelessness and non-routine health service use without an increase in problematic substance use. Impacts on long-term health outcomes require further investigation.

Gender differences in acute recreational drug toxicity: a case series from Oslo, Norway

BACKGROUND

Female drug users report poorer physical and mental health than male drug users. We describe female and male patients treated for acute recreational drug toxicity, and look for gender differences in clinical state, treatment, and toxic agents taken.

METHODS

Retrospective case series from a primary care emergency outpatient clinic and a hospital emergency department in Oslo, Norway. All patients treated for acute recreational drug toxicity from October 2013 through March 2015 were included, except patients with lone alcohol intoxication. Patients were grouped according to whether they had taken opioids or not, as a proxy differentiation between heavy drug users and party drug users. Data from the two clinical settings were analysed separately.

RESULTS

In total, 2495 cases were included, 567 (22.7%) were women. Female patients were younger than males, median 31 vs 34 years (p < 0.001). On most comparisons of clinical variables there were no significant differences between genders. A larger proportion of females in the outpatient opioid group were hypotensive, 10.9% vs 3.9% (p < 0.001). Fewer females were intubated, none vs 21.1% (p = 0.019) in the hospital opioid group, and 6.4% vs 21.0% (p = 0.039) in the hospital non-opioid group. The proportion of gamma-hydroxybutyrate (GHB) poisoning was larger among females both at the outpatient clinic (14.4% vs 8.6%, p < 0.001) and at the hospital (60.3% vs 36.4%, p = 0.001), while the proportion of heroin poisoning was smaller among females at the outpatient clinic (37.1% vs 47.0%, p < 0.001).

CONCLUSION

One in four patients treated for acute recreational drug toxicity were women. Female patients were younger, had more frequently taken GHB and were less frequently intubated. Otherwise, the gender differences regarding clinical state and treatment were small. Although female drug users are known to report poorer health than males, we did not find that women had a more severe clinical course than men when presenting with overdose.

Health-related quality of life and prevalence of six chronic diseases in homeless and housed people: a cross-sectional study in London and Birmingham, England

OBJECTIVES

To compare health-related quality of life and prevalence of chronic diseases in housed and homeless populations.

DESIGN

Cross-sectional survey with an age-matched and sex-matched housed comparison group.

SETTING

Hostels, day centres and soup runs in London and Birmingham, England.

PARTICIPANTS

Homeless participants were either sleeping rough or living in hostels and had a history of sleeping rough. The comparison group was drawn from the Health Survey for England. The study included 1336 homeless and 13 360 housed participants.

OUTCOME MEASURES

Chronic diseases were self-reported asthma, chronic obstructive pulmonary disease (COPD), epilepsy, heart problems, stroke and diabetes. Health-related quality of life was measured using EQ-5D-3L.

RESULTS

Housed participants in more deprived neighbourhoods were more likely to report disease. Homeless participants were substantially more likely than housed participants in the most deprived quintile to report all diseases except diabetes (which had similar prevalence in homeless participants and the most deprived housed group). For example, the prevalence of chronic obstructive pulmonary disease was 1.1% (95% CI 0.7% to 1.6%) in the least deprived housed quintile; 2.0% (95% CI 1.5% to 2.6%) in the most deprived housed quintile; and 14.0% (95% CI 12.2% to 16.0%) in the homeless group. Social gradients were also seen for problems in each EQ-5D-3L domain in the housed population, but homeless participants had similar likelihood of reporting problems as the most deprived housed group. The exception was problems related to anxiety, which were substantially more common in homeless people than any of the housed groups.

CONCLUSIONS

While differences in health between housed socioeconomic groups can be described as a 'slope', differences in health between housed and homeless people are better understood as a 'cliff'.

Aboriginal mothers in prison in Australia: a study of social, emotional and physical wellbeing

OBJECTIVE

To describe the social, emotional and physical wellbeing of Aboriginal mothers in prison.

METHODS

Cross-sectional survey, including a Short Form Health Survey (SF-12) and Kessler Psychological Distress Scale (5-item version) administered to Aboriginal women who self-identified as mothers.

RESULTS

Seventy-seven Aboriginal mothers in New South Wales (NSW) and 84 in Western Australia (WA) participated in the study. Eighty-three per cent (n=59) of mothers in NSW were in prison for drug-related offences, 64.8% (n=46) of mothers in WA were in prison for offences committed under the influence of alcohol. Sixty-eight per cent (n=52) of mothers in NSW and 35% (n=28) of mothers in WA reported mental health problems. Physical (PCS) and Mental (MCS) component scores of SF-12 varied for mothers in NSW and WA. Mothers in NSW experienced poorer health and functioning than mothers in WA (NSW: PCS 49.5, MCS 40.6; WA: PCS 54.4, MCS 48.3) and high levels of psychological distress (NSW: 13.1; WA 10.1).

CONCLUSIONS

Aboriginal mothers in prison have significant health needs associated with physical and mental health, and psychological distress. Implications for public health: Adoption of social and emotional wellbeing as an explanatory framework for culturally secure healthcare in prison is essential to improving health outcomes of Aboriginal mothers in prison in Australia.

Re-emergence of HIV related to injecting drug use despite a comprehensive harm reduction environment: a cross-sectional analysis

BACKGROUND

In 2015, an outbreak of HIV was identified among people who inject drugs (PWID) in the Greater Glasgow and Clyde (GGC) area of Scotland, an area which distributes more than 1 million needles and syringes per year. This is the largest such incident in the UK for 30 years. Here, we provide an epidemiological analysis of the impact of the outbreak on HIV prevalence trends in the population and the individual and environmental risk factors associated with infection.

METHODS

Four cross-sectional, anonymous, bio-behavioural surveys of almost 4000 PWID attending services providing injecting equipment across GGC between 2011 and 2018 were analysed. Participants were recruited by trained independent interviewers and eligible if they had a history of injecting drug use, either current (within the past 6 months) or historical. Interviewers asked participants questions about demographics, behaviours, and service use and to give a dried blood spot sample that was tested anonymously for the presence of blood-borne viruses. Our primary outcome measure was HIV infection status, as determined by the dried blood spot sample. We removed duplicates and participants with missing data and used all remaining participants to examine trends in prevalence of HIV infection, risk behaviours, and intervention coverage. We then did multivariate analysis with adjusted and unadjusted logistic regression to determine individual and environmental factors associated with HIV infection.

FINDINGS

The overall GGC sample comprised 3641 PWID; data from 2712 PWID were available for multivariate analysis after further removal of duplicate participants and missing data. Between 2011 and 2018, HIV prevalence in GGC rose from 0·1% (95% CI 0·0-0·6) to 4·8% (3·4-6·2) overall, and from 1·1% (0·2-6·2) to 10·8% (7·4-15·5) in Glasgow city centre. Over the same period, the prevalence of cocaine injecting in all individuals in GGC in our sample rose from 16% (129/805) to 50% (291/583) overall, and from 37% (26/70) to 77% (117/153) in Glasgow city centre. HIV infection was more likely among PWID who had participated in surveys after the start of the outbreak in 2014 (adjusted odds ratio 3·4, 95% CI 1·7-6·7; p=0·00052), been homeless in the past 6 months (3·0, 1·7-5·0; p<0·0001), had had more than five incarcerations since they first began injecting (2·1, 1·2-3·7; p=0·0098); and had injected cocaine within the past 6 months (6·7, 3·8-12·1; p<0·0001). Age (per 1-year increase) was also a significant factor (1·1, 1·0-1·1; p=0·0016) but sex was not (1·7, 0·9-3·2; p=0·083).

INTERPRETATION

Despite high coverage of harm reduction interventions, Glasgow has experienced a rapid rise in prevalence of HIV among its PWID population, associated with homelessness, incarceration, and a major shift to injection of cocaine. Robust surveillance through regular HIV testing of high-risk populations is crucial to ensure outbreaks are detected and rapid responses are informed by the best available evidence.

Age-specific incidence of injury-related hospital contact after release from prison: a prospective data-linkage study

Background

In population studies, the risk of injury declines after early adulthood. It is unclear if a similar age difference in the risk of injury exists among people released from prison.

Methods

Prerelease survey data collected between 1 August 2008 and 31 July 2010, from a representative cohort of sentenced adults (≥18 years) in Queensland, Australia, were linked prospectively and retrospectively to person-level emergency department, inpatient hospital and correctional records. To ascertain predictors of injury-related hospital contact, we fit a multivariate Andersen-Gill model and tested the interactions between age group (<25 years, ≥25 years) and each variable.

Results

In 1307 adults released from prison, there were 3804 person-years of follow-up. The crude injury rate was 385 (95% CI 364 to 407) per 1000 person-years and did not differ according to age group. Factors associated with increased injury-related hospital contact included a history of mental illness, preincarceration injury, a history of incarceration, release from a short prison sentence (<90 days), being reincarcerated during follow-up and identifying as Indigenous. The effect of mental illness, risky alcohol use, prior incarceration and intellectual disability differed across age group and predicted increased risk of injury among people aged ≥25 years compared with their counterparts without these characteristics.

Conclusions

Unlike in the general population where the risk of injury declines with age, older adults released from prison are at similar risk compared with their younger peers. Adults released from prison with mental illness, a history of injury-related hospital contact and who identify as Indigenous are particularly indicated groups for injury prevention.

A mixed methods randomised control trial to evaluate the effectiveness of the journey to social inclusion - phase 2 intervention for chronically homeless adults: study protocol

BACKGROUND

Chronic homelessness is a problem characterised by longstanding inability to attain or maintain secure accommodation. Longitudinal research with homeless populations is challenging, and randomised controlled trials that evaluate the effectiveness of intensive, case management interventions aimed at improving housing and health-related outcomes for chronically homelessness people are scant. More research is needed to inform programmatic design and policy frameworks in this area. This study protocol details an evaluation of the Journey to Social Inclusion - Phase 2 program, an intervention designed to reduce homelessness and improve outcomes in chronically homeless adults.

METHODS/DESIGN

J2SI Phase 2 is a three-year, mixed methods, multi-site, RCT that enrolled 186 participants aged 25 to 50 years between 07 January 2016 and 30 September 2016 in Melbourne. The intervention group (n = 90 recruited) receives the J2SI Phase 2 program, a trauma-informed intervention that integrates intensive case management and service coordination; transition to housing and support to sustain tenancy; and support to build social connections, obtain employment and foster independence. The comparison group (n = 96 recruited) receives standard service provision. Prior to randomisation, participants completed a baseline survey. Follow-up surveys will be completed every six months for three years (six in total). In addition to self-report data on history of homelessness and housing, physical and mental health, substance use, quality of life, social connectedness and public service utilisation, linked administrative data on participants' public services utilisation (e.g., hospitalisation, justice system) will be obtained for the three-year period pre- and post-randomisation. Semi-structured, qualitative interviews will be conducted with a randomly selected subset of participants and service providers at three time-points to explore changes in key outcome variables and to examine individual experiences with the intervention and standard service provision. An economic evaluation of the intervention and associated costs will also be undertaken.

DISCUSSION

Results of this trial will provide robust evidence on the effectiveness of J2SI Phase 2 compared to standard service provision. If the intervention demonstrates effectiveness in improving housing, health, quality-of-life, and other social outcomes, it may be considered for broader national and international dissemination to improve outcomes among chronically homeless adults.

Association of Methadone Treatment With Substance-Related Hospital Admissions Among a Population in Canada With a History of Criminal Convictions

IMPORTANCE

People with criminal histories experience high rates of opioid dependence and are frequent users of acute health care services. It is unclear whether methadone adherence prevents hospitalizations.

OBJECTIVE

To compare hospital admissions during medicated and nonmedicated methadone periods.

DESIGN, SETTING, AND PARTICIPANTS

A retrospective cohort study involving linked population-level administrative data among individuals in British Columbia, Canada, with provincial justice contacts (n= 250 884) and who filled a methadone prescription between April 1, 2001, and March 31, 2015. Participants were followed from the date of first dispensed methadone prescription until censoring (date of death, or March 31, 2015). Data analysis was conducted from May 1 to August 31, 2018.

EXPOSURES

Methadone treatment was divided into medicated (methadone was dispensed) and nonmedicated (methadone was not dispensed) periods and analyzed as a time-varying exposure.

MAIN OUTCOME AND MEASURES

Adjusted hazard ratios (aHRs) of acute hospitalizations for any cause and cause-specific (substance use disorder [SUD], non-substance-related mental disorders [NSMDs], and medical diagnoses [MEDs]) were estimated using multivariable Cox proportional hazards regression.

RESULTS

A total of 11 401 people (mean [SD] age, 34.9 [9.4] years; 8230 [72.2%] men) met inclusion criteria and were followed up for a total of 69 279.3 person-years. During a median follow-up time of 5.5 years (interquartile range, 2.8-9.1 years), there were 19 160 acute hospital admissions. Dispensed methadone was associated with a 50% lower rate of hospitalization for any cause (aHR, 0.50; 95% CI, 0.46-0.53) during the first 2 years (≤2.0 years) following methadone initiation, demonstrating significantly lower rates of admission for SUD (aHR, 0.32; 95% CI, 0.27-0.38), NSMD (aHR, 0.41; 95% CI, 0.34-0.50), and MED (aHR, 0.57; 95% CI, 0.52-0.62). As duration of time increased (2.1 to ≤5.0 years; 5.1 to ≤10.0 years), methadone was associated with a significant but smaller magnitude of effect: SUD (aHR, 0.43; 95% CI, 0.36-0.52; aHR, 0.47; 95% CI, 0.37-0.61), NSMD (aHR, 0.51; 95% CI, 0.41-0.64; aHR, 0.60; 95% CI, 0.47-0.78), and MED (aHR, 0.71; 95% CI, 0.65-0.77; aHR, 0.85; 95% CI, 0.76-0.95).

CONCLUSIONS AND RELEVANCE

In this study, methadone was associated with a lower rate of hospitalization among a large cohort of Canadian individuals with histories of convictions and prevalent concurrent health and social needs. Practices to improve methadone adherence are warranted.

Perceived roles and barriers in caring for the people who are homeless: a survey of UK community pharmacists

Background Community pharmacists can be an accessible source for advice and support for the people who are homeless, given their utilisation of a variety of currently available services such as dispensing of medicines, drugs and alcohol services. Objective To determine community pharmacists' training, experiences and behavioural determinants in counselling and management of homeless population. Setting UK community pharmacies. Method A questionnaire based on literature and theoretical domains framework was mailed to randomly sampled community pharmacies in England and Scotland (n = 2000). Data were analysed using descriptive and inferential statistics. Main outcome measures Pharmacists' perspectives, pharmacists' training, pharmacists' experiences and behavioural determinants. Results A total of 321 responses (RR 16.1%) were received. Respondents indicated lack of knowledge, skills, intentions as well as contextual factors such as lack of guidelines impacted on their counselling and management of homeless patients. Less than a third (n = 101, 32.2%) indicated that they knew where to refer a homeless patient for social support. Broaching the subject of homelessness was outside their comfort zone (n = 139, 44.3%). Only four (1.2%) respondents could correctly answer all knowledge assessment questions. Conclusions Community pharmacist identified lack of education, training opportunities and guidelines in counselling and management of homeless patients. Targeting community pharmacists' knowledge, skills and intention to provide care to the homeless patients may enable addressing health inequality through community pharmacy.

Emergence of Novel Psychoactive Substance injecting associated with rapid rise in the population prevalence of hepatitis C virus

BACKGROUND

Novel Psychoactive Substance (NPS) use has increased in recent years and generated significant concern within public health. People who inject drugs (PWID) are at increased risk of blood borne viruses, in particular Hepatitis C virus (HCV). However, little is known about the extent of NPS injecting at a national level and its association with HCV. This study provides one of the first epidemiological analyses of the association between NPS injecting and HCV among a population level sample of PWID.

METHODS

Five cross sectional surveys of almost 13,000 PWID attending services providing injecting equipment across Scotland between 2008 and 2016 were analysed. Logistic regression was used to determine associations between NPS injecting and HCV.

RESULTS

The proportion of PWID reporting that they had injected NPS in the previous six months increased from 0.2% in 2008-09 to 11.0% in 2015-16. Those who reported injecting NPS were considerably more likely to be resident in the Lothian NHS Board area at the time of the study (AOR 5.6 (95% CI 4.1-7.5)) and to have had recent experience of homelessness (AOR 1.4 (95% CI 1.0-1.9)). People who injected NPS were also significantly more likely to be HCV positive (AOR 1.7 (95% CI 1.2-2.4)). In Lothian, HCV prevalence rose from around 30% between 2008 and 2012 to 41% and then 48% in 2013-14 and 2015-16 respectively. Increases in prevalent HCV infection in Lothian may be partly attributed to increases in NPS injecting.

CONCLUSION

In Scotland, people who had injected Novel Psychoactive Substances were at increased risk of hepatitis C virus. Novel Psychoactive Substance injecting poses a threat to HCV elimination strategies.

Five-year standardised mortality ratios in a cohort of homeless people in Dublin

OBJECTIVE

To calculate standardised mortality ratios (SMRs) for a cohort of homeless people in the Dublin region over a 5-year period and to examine leading causes of death.

SETTING

Homeless services reporting deaths from homeless persons in their care across the Dublin Homeless Region.

METHODS

Death data among people who experience homelessness was acquired from the Dublin Region Homeless Executive (2011-2015) and validated from both death certificates and records from the Dublin Coroner's Office.

PARTICIPANTS

Two hundred and nine deaths were recorded; of these 201 were verified (n=156 males, 77.6%). Deaths that could not be verified by certificate or coroners record were excluded from the study.

RESULTS

SMRs were 3-10 times higher in homeless men and 6-10 times higher in homeless women compared with the general population. Drug and alcohol-related deaths were the leading cause of death, accounting for 38.4% of deaths in homeless individuals. These were followed by circulatory (20%) and respiratory causes (13%).

CONCLUSION

Mortality rates among homeless persons are exceptionally high. Services and programmes, particularly housing and those targeting overdose and alcoholism, are urgently needed to prevent premature mortality in this vulnerable population.

Modelling the decline and future of hepatitis A transmission in Australia

Hepatitis A incidence has declined in most countries through a combination of prevention measures, augmented through the use of a highly effective vaccine. In Australia, the proportion of the population susceptible to hepatitis A infection has declined over time due to high rates of opportunistic vaccination as well as the sustained inflow of seropositive immigrants from high-endemicity countries. These factors have contributed to a rapid decline in incidence. An age-structured hepatitis A transmission model incorporating demographic changes was fitted to seroprevalence and disease notification data and used to project incidence trends and transmission potential for hepatitis A in the general population. Robustness of findings was assessed through worst-case scenarios regarding vaccine uptake, migration and the duration of immunity. The decline in age-specific seroprevalence until the introduction of hepatitis A vaccine in 1994 was well explained through a declining basic reproduction number (R₀ ) that remained >1. Accounting for existing immunity, we estimated that the effective reproduction number (R_eff ) <1 in the general population of Australia since the early 1990s, declining more rapidly after the introduction of the hepatitis A vaccine. Future projections under a variety of scenarios support R_eff remaining <1 with continued low incidence in the general population. In conclusion, our results suggest that sustained endemic transmission in the general Australian population is no longer possible although risks of sporadic outbreaks remain. This suggests potential for local elimination of hepatitis A infection in Australia, provided that elimination criteria can be defined and satisfied in risk groups. The methodology used here to investigate elimination potential can easily be replicated in settings such as in the USA where sequential seroprevalence studies are supported by routine notification data.

Enhancing Access to Physical Therapy Services for People Experiencing Poverty and Homelessness: The Lighthouse Pilot Project

Purpose: Our aim was to reveal client and provider perspectives on the impact of enhancing access to physical therapy services in a primary health care community-based setting. Method: Clients of The Lighthouse Supported Living facility in Saskatoon, Saskatchewan, who accessed physical therapy services over a 4-month pilot period and health care providers (physical therapists and a nurse practitioner) provided qualitative data (through interviews and an online discussion board). Client demographics, health condition, perceived function, quality of life, and satisfaction were obtained through chart review and questionnaires. Results: Forty-seven clients ranging in age from 21 to 72 years (mean 47 y) participated in the pilot project. Most presented with a musculoskeletal issue (85.1%). Analysis of the qualitative data gathered from client and provider participants revealed the following four overarching themes: (1) complex health challenges, unmet needs; (2) overcoming access barriers and impact of physical therapy services; (3) respecting and responding to context and environment; and (4) moving forward to enhance access to physical therapy care. Conclusions: Individuals experiencing homelessness and poverty face diverse barriers to accessing physical therapy services, including transportation, cost, wait times, and geographical location. Clients who accessed physical therapy services at The Lighthouse perceived a positive impact on their overall health, function, and wellness.

Understanding and Improving the Health of People Who Experience Incarceration: An Overview and Synthesis

The world prison population is growing at a rate that exceeds the rate of population growth. This issue of Epidemiologic Reviews comprises articles in which researchers summarize what is known about some of the key health issues facing people in prison, particularly in relation to human immunodeficiency virus and other blood-borne viral infections. A key recurring theme is that addressing the health needs of people in prison is important to reducing health inequalities at the population level—that prisoner health is public health. The reviews also highlight some critical evidence gaps, notably the lack of evidence from low- and middle-income countries, and the limited number of longitudinal studies in which health behaviors, health outcomes, or health service experiences after release from prison are documented. Despite growing evidence of the poor health of detained adolescents, none of the included reviews considered this population. Further research on the health of young people who cycle through juvenile detention should be a priority. Despite a rapidly growing literature on the health of people who experience incarceration, some critical health issues remain poorly understood, and there has been insufficient attention devoted to co-occurring health conditions and the consequent need for coordinated care. Key populations in custodial settings remain understudied, limiting capacity to develop targeted, evidence-based responses to their health needs. The quality of many studies is suboptimal, and although rigorous, independent research in correctional settings can be challenging, it is not impossible and is critical to laying the groundwork for evidence-based reform.

Global patterns of mortality in international migrants: a systematic review and meta-analysis

BACKGROUND

258 million people reside outside their country of birth; however, to date no global systematic reviews or meta-analyses of mortality data for these international migrants have been done. We aimed to review and synthesise available mortality data on international migrants.

METHODS

In this systematic review and meta-analysis, we searched MEDLINE, Embase, the Cochrane Library, and Google Scholar databases for observational studies, systematic reviews, and randomised controlled trials published between Jan 1, 2001, and March 31, 2017, without language restrictions. We included studies reporting mortality outcomes for international migrants of any age residing outside their country of birth. Studies that recruited participants exclusively from intensive care or high dependency hospital units, with an existing health condition or status, or a particular health exposure were excluded. We also excluded studies limited to maternal or perinatal outcomes. We screened studies using systematic review software and extracted data from published reports. The main outcomes were all-cause and International Classification of Diseases, tenth revision (ICD-10) cause-specific standardised mortality ratios (SMRs) and absolute mortality rates. We calculated summary estimates using random-effects models. This study is registered with PROSPERO, number CRD42017073608.

FINDINGS

Of the 12 480 articles identified by our search, 96 studies were eligible for inclusion. The studies were geographically diverse and included data from all global regions and for 92 countries. 5464 mortality estimates for more than 15·2 million migrants were included, of which 5327 (97%) were from high-income countries, 115 (2%) were from middle-income countries, and 22 (<1%) were from low-income countries. Few studies included mortality estimates for refugees (110 estimates), asylum seekers (144 estimates), or labour migrants (six estimates). The summary estimate of all-cause SMR for international migrants was lower than one when compared with the general population in destination countries (0·70 [95% CI 0·65-0·76]; I2=99·8%). All-cause SMR was lower in both male migrants (0·72 [0·63-0·81]; I2=99·8%) and female migrants (0·75 [0·67-0·84]; I2=99·8%) compared with the general population. A mortality advantage was evident for refugees (SMR 0·50 [0·46-0·54]; I2=89·8%), but not for asylum seekers (1·05 [0·89-1·24]; I2=54·4%), although limited data was available on these groups. SMRs for all causes of death were lower in migrants compared with the general populations in the destination country across all 13 ICD-10 categories analysed, with the exception of infectious diseases and external causes. Heterogeneity was high across the majority of analyses. Point estimates of all-cause age-standardised mortality in migrants ranged from 420 to 874 per 100 000 population.

INTERPRETATION

Our study showed that international migrants have a mortality advantage compared with general populations, and that this advantage persisted across the majority of ICD-10 disease categories. The mortality advantage identified will be representative of international migrants in high-income countries who are studying, working, or have joined family members in these countries. However, our results might not reflect the health outcomes of more marginalised groups in low-income and middle-income countries because little data were available for these groups, highlighting an important gap in existing research. Our results present an opportunity to reframe the public discourse on international migration and health in high-income countries.

Evaluation of training on palliative care for staff working within a homeless hostel

BACKGROUND

In the UK, many people experiencing homelessness whose health is deteriorating remain in homeless hostels due to few suitable alternative places of care. Hostel staff struggle to support residents with deteriorating health and palliative care services are rarely involved. There is recognition of the need for multiagency working to support this group.

OBJECTIVES

To pilot and evaluate the impact of a two-day training course for hostel staff around supporting clients with palliative care needs, and increasing multiagency working.

DESIGN

Mixed methods evaluation using pre-and-post training data collection.

SETTINGS AND PARTICIPANTS

Frontline staff from two London homeless hostels.

METHODS

Staff from two hostels attended a two day training course. Self-perceived confidence in supporting residents with deteriorating health, knowledge of palliative care, openness to discussing deteriorating health and work related stress were assessed at baseline and immediately after training using a novel questionnaire. Qualitative data was collected via focus groups immediately after and three months post-training.

RESULTS

Twenty four participants attended at least one day of training, 21 (87%) completed the course. Training was reported to be useful and relevant. Modest improvements in self-perceived work related stress, knowledge, confidence and openness were observed following training. At three months, qualitative data indicated the beginnings of a shift in how palliative care was conceptualised and an increase in knowledge and confidence around supporting residents. Anxiety regarding the role of the hostel in palliative care, the recovery focused ethos of homelessness services and fragmented systems and services presented challenges to establishing changes.

CONCLUSIONS

Training can be useful for improving knowledge, confidence, openness and work related stress. Recommendations for implementing changes in how people experiencing homelessness are supported include embedding training into routine practice, promoting multidisciplinary working, incorporating flexibility within the recovery focused approach of services and recognising the need for emotional support for staff.

Access to palliative care for homeless people: complex lives, complex care

BACKGROUND

People experiencing homelessness often encounter progressive incurable somatic diseases in combination with psychiatric and psychosocial problems, and many need palliative care at the end of their lives. Little is known about how palliative care for this group can be started in good time and provided optimally. The objective of this paper is to give insight into the extent people experiencing homelessness have access to good palliative care.

METHODS

Qualitative in-depth interviews were held to reconstruct the cases of 19 people experiencing homelessness in the Netherlands. Eight cases concerned persons being in the palliative phase (using the surprise question) and the other 11 cases concerned persons recently died after a period of ill health due to somatic illness. We used purposive sampling until data saturation was reached. The total number of interviews was 52. All interviews were transcribed verbatim and analysed inductively.

RESULTS

Three key themes were: 'late access', 'capricious trajectory' and 'complex care'. The first key theme refers to the often delayed start of palliative care, because of the difficulties in recognizing the need for palliative care, the ambivalence of people experiencing homelessness about accepting palliative care, and the lack of facilities with specific expertise in palliative care for them. The second key theme refers to the illness trajectory, which is often capricious because of the challenging behaviour of people experiencing homelessness, an unpredictable disease process and a system not being able to accommodate or meet their needs. The third key theme refers to the complexity of their care with regard to pain and symptom control, psychosocial and spiritual aspects, and the social network.

CONCLUSIONS

The care for in the palliative phase does not satisfy the core requirements of palliative care since there are bottlenecks regarding timely identification, the social network, and the assessment and management of physical symptoms and psychosocial and spiritual care needs. Education in palliative care of outreach professionals, training staff in shelters in the provision of palliative care, and building a network of palliative care specialists for people experiencing homelessness.

Predictors of treatment initiation for alcohol use disorders in primary care

BACKGROUND

We identified predictors of receiving treatment (brief therapy [BT] and/or extended-release injectable naltrexone [XR-NTX]) for the treatment of alcohol use disorders (AUDs) in primary care. We also examined the relationship between receiving BT and XR-NTX.

METHODS

Secondary data analysis of SUMMIT, a randomized controlled trial of collaborative care. Participants were 290 individuals with AUDs who reported no past 30-day opioid use and who were receiving primary care at a multi-site Federally Qualified Health Center. Bivariate and multivariate analyses examined predictors of BT and/or XR-NTX.

RESULTS

Thirty-two percent (N = 93) received either BT or XR-NTX, 28% (N = 82) received BT and 13% (N = 37) received XR-NTX; 9% (N = 26) received both BT and XR-NTX. Older age, white race, talking with a professional about alcohol use and having more negative consequences all predicted receipt of evidence-based treatment; being homeless was a negative predictor. The predictors of receiving BT included not being homeless and previously talking with a professional; the predictors of receiving XR-NTX included older age, white race and experiencing more negative consequences. In 80% of those who received both BT and XR-NTX, receipt of BT preceded XR-NTX.

CONCLUSIONS

Patient factors were important predictors of receiving primary-care based AUD treatment and differed by type of treatment received. Receiving BT was associated with subsequent use of XR-NTX and may be associated with a longer duration of XR-NTX treatment. Providers should consider these findings when considering ways to increase primary-care based AUD treatment.

Dual Use and Hospital Admissions among Veterans Enrolled in the VA's Homeless Patient Aligned Care Team

OBJECTIVE

To examine the association between reliance on VA outpatient care and hospital admissions among Medicare-eligible Veterans enrolled in the Homeless Patient Aligned Care Team (H-PACT).

DATA SOURCES/STUDY SETTING

Registry of H-PACT enrollees linked to VA and Medicare utilization data for 2013.

STUDY DESIGN

After assigning Veterans to two groups according to whether they received >90 percent of outpatient care in VA (higher reliance) or <90 percent of outpatient care in VA (lower reliance), generalized linear models with inverse probability of treatment weights were used to estimate the association of reliance with Medicare and VA-financed hospital admissions.

PRINCIPAL FINDINGS

Compared with higher reliance Veterans, lower reliance Veterans had an equivalent number of annual VA hospitalizations (0.63 vs. 0.50; p = .14) but substantially greater Medicare hospitalizations (0.85 vs. 0.08; p < .001). Among Veterans in the highest tertile of outpatient visits, we observed statistically similar rates of VA hospital use but over 10-fold greater rates of Medicare-financed hospitalizations (1.31 for lower reliance vs. 0.15 for high reliance; p < .001).

CONCLUSIONS

Among Veterans receiving integrated care in VA's H-PACT, dual use of Medicare and VA outpatient care is strongly associated with acute hospitalizations financed by Medicare. Linking VA and non-VA data may identify a subset of homeless Veterans with fragmented outpatient care who are at increased risk of poor outcomes.

Health Literacy Among a Formerly Incarcerated Population Using Data from the Transitions Clinic Network

Health literacy is increasingly understood to be a mediator of chronic disease self-management and health care utilization. However, there has been very little research examining health literacy among incarcerated persons. This study aimed to describe the health literacy and relevant patient characteristics in a recently incarcerated primary care patient population in 12 communities in 6 states and Puerto Rico. Baseline data were collected from 751 individuals through the national Transitions Clinic Network (TCN), a model which utilizes a community health worker (CHW) with a previous history of incarceration to engage previously incarcerated people with chronic medical diseases in medical care upon release. Participants in this study completed study measures during or shortly after their first medical visit in the TCN. Data included demographics, health-related survey responses, and a measure of health literacy, The Newest Vital Sign (NVS). Bivariate and linear regression models were fit to explore associations among health literacy and the time from release to first clinic appointment, number of emergency room visits before first clinic appointment and confidence in adhering to medication. Our study found that almost 60% of the sample had inadequate health literacy. Inadequate health literacy was associated with decreased confidence in taking medications following release and an increased likelihood of visiting the emergency department prior to primary care. Early engagement may improve health risks for this population of individuals that is at high risk of death, acute care utilization, and hospitalization following release.
