Supporting Harm Reduction through Peer Support (SHARPS): testing the feasibility and acceptability of a peer-delivered, relational intervention for people with problem substance use who are homeless, to improve health outcomes, quality of life and social functioning and reduce harms: study protocol

Feasibility, acceptability, and perceived usefulness of a community-evidence-based harm reduction intervention for sexualized stimulant use among Mexican gay, bisexual, and other men who have sex with men

BACKGROUND

The use of stimulants and other substances with the purpose of enhancing, maintaining, and prolonging sexual activity is known as sexualized substance use. Also known as chemsex, this pattern of use has been mainly explored in high-income countries. The aim of this article was to assess the feasibility, acceptability, and usefulness of a community- evidence-based harm reduction intervention among Mexican gay, bisexual, and other men who have sex with men (gbMSM) adults who reported sexualized stimulant use in the past 6 months and who were not enrolled in any psychosocial treatment.

METHODS

The in-person intervention was designed in partnership with gbMSM who used substances. It consisted of 39 harm reduction strategies before, during, and after episodes of use. The components of the intervention were health and self-care, safety, and psychopharmacology. The intervention was delivered at a university campus, a public recreational space, and an HIV public clinic. Feasibility to deliver the intervention was assessed based on enrolment and completion rates; acceptability through a 28-item, 5-point Likert scale (140 max.) constructed and validated for the Mexican population with good reliability coefficients; usefulness through a 5-point Likert scale ("not useful"-"very useful") for each of the 39 strategies; and potential behavioral change by subtracting the likelihood of implementing each strategy minus the frequency of use of the technique before the intervention.

RESULTS

Participants (n = 19; recruitment rate = 35.2%; completion rate = 84.2%) rated the intervention as acceptable with a mean score of 121.6 (SD = 7.5). The highest potential for behavioral change was regarding the use of information about the half-life of stimulants, polysubstance use, and overdose prevention.

CONCLUSIONS

This intervention is feasible when provided within public health services where potential participants are already in contact. Harm reduction strategies need to surpass sexually transmitted infections prevention and HIV care and focus on substance use and mental health strategies.

Gender, homelessness, hospitalization and methamphetamine use fuel depression among people who inject drugs: implications for innovative prevention and care strategies

Background

The co-occurrence of substance use disorder and mental disorder, known as dual diagnosis, has a distressingly high prevalence among individuals grappling with either of these conditions. Mood disorders, especially depression, constitute a substantial burden for People Who Inject Drugs (PWID) and a significant public health concern in Vietnam. Identifying risk factors for depression in PWID is imperative for the development of targeted interventions.

Methods

We enrolled PWID into a cohort using the respondent-driven sampling method. Over a 36-month period, we systematically tracked the emergence of depression and employed multiple imputation in conjunction with a mixed nonlinear model to pinpoint risk factors for depression in this demographic. At inclusion, depression was screened using the PHQ-2 questionnaire, and subsequent episodes of depression were assessed semi-annually using the CES-D8.

Results

Three hundred and ninety-one PWID (26.6%) were depressed. Major risk factors for depression included being female, not having a permanent residency, having been hospitalized and using methamphetamine more than weekly. Other risk factors included age, being single, not having a health insurance card and not being on methadone.

Limitations

The exclusion of missing visits and social desirability could have led to selection and information biases. In this observational study, confusion biases are possible despite our best efforts.

Conclusion

Depression is alarmingly frequent in PWID. In this study taking in account the chronological relationship between sociodemographic and clinical factors and depression, risk factors were identified in this specific setting of low-to-middle income country. The findings highlight the need to develop innovative targeted psychiatric interventions with the help of supporting peers.

Assessing the feasibility, acceptability and accessibility of a peer-delivered intervention to reduce harm and improve the well-being of people who experience homelessness with problem substance use: the SHARPS study

BACKGROUND

For people experiencing homelessness and problem substance use, access to appropriate services can be challenging. There is evidence that the development of trusting relationships with non-judgemental staff can facilitate service engagement. Peer-delivered approaches show particular promise, but the evidence base is still developing.

METHODS

The study used mixed methods to assess the feasibility, acceptability and accessibility of a peer-delivered, relational intervention to reduce harms and improve health/well-being, quality of life and social functioning, for people experiencing homelessness and problem substance use. Four Peer Navigators were employed to support individuals (n = 68 total, intervention participants). They were based in outreach services and hostels in Scotland and England. Qualitative interviews were conducted with intervention participants, Peer Navigators and staff in services, and observations were conducted in all settings. Quantitative outcomes relating to participants' substance use, physical and mental health, and quality of the Peer Navigator relationship, were measured via a 'holistic health check' with six questionnaires completed at two time-points.

RESULTS

The intervention was found to be acceptable to, and feasible and accessible for, participants, Peer Navigators, and service staff. Participants reported improvements to service engagement, and feeling more equipped to access services independently. The lived experience of the Peer Navigators was highlighted as particularly helpful, enabling trusting, authentic, and meaningful relationships to be developed. Some challenges were experienced in relation to the 'fit' of the intervention within some settings. Among participants there were reductions in drug use and risky injecting practices. There were increases in the number of participants receiving opioid substitution therapy. Overall, the intervention was positively received, with collective recognition that the intervention was unique and highly valuable. While most of the measures chosen for the holistic health check were found to be suitable for this population, they should be streamlined to avoid duplication and participant burden.

CONCLUSIONS

The study established that a peer-delivered, relational harm reduction intervention is acceptable to, and feasible and accessible for, people experiencing homelessness and problem substance use. While the study was not outcomes-focused, participants did experience a range of positive outcomes. A full randomised controlled trial is now required to assess intervention effectiveness.

A peer-delivered intervention to reduce harm and improve the well-being of homeless people with problem substance use: the SHARPS feasibility mixed-methods study

BACKGROUND

For people experiencing homelessness and problem substance use, access to appropriate services can be challenging. There is evidence that development of trusting relationships with non-judgemental staff can facilitate service engagement. Peer-delivered approaches show particular promise, but the evidence base is still developing. This study tested the feasibility and acceptability of a peer-delivered intervention, through 'Peer Navigators', to support people who are homeless with problem substance use to address a range of health and social issues.

OBJECTIVES

The study objectives were to design and implement a peer-delivered, relational intervention to reduce harms and improve health/well-being, quality of life and social functioning for people experiencing homelessness and problem substance use, and to conduct a concurrent process evaluation to inform a future randomised controlled trial.

DESIGN

A mixed-methods feasibility study with concurrent process evaluation was conducted, involving qualitative interviews [staff interviews (one time point), n = 12; Peer Navigator interviews (three or four time points), n = 15; intervention participant interviews: first time point, n = 24, and second time point, n = 10], observations and quantitative outcome measures.

SETTING

The intervention was delivered in three outreach services for people who are homeless in Scotland, and three Salvation Army hostels in England; there were two standard care settings: an outreach service in Scotland and a hostel in England.

PARTICIPANTS

Participants were people experiencing homelessness and problem substance use (n = 68) (intervention).

INTERVENTION

This was a peer-delivered, relational intervention drawing on principles of psychologically informed environments, with Peer Navigators providing practical and emotional support.

MAIN OUTCOME MEASURES

Outcomes relating to participants' substance use, participants' physical and mental health needs, and the quality of Peer Navigator relationships were measured via a 'holistic health check', with six questionnaires completed at two time points: a specially created sociodemographic, health and housing status questionnaire; the Patient Health Questionnaire-9 items plus the Generalised Anxiety Disorder-7; the Maudsley Addiction Profile; the Substance Use Recovery Evaluator; the RAND Corporation Short Form survey-36 items; and the Consultation and Relational Empathy Measure.

RESULTS

The Supporting Harm Reduction through Peer Support (SHARPS) study was found to be acceptable to, and feasible for, intervention participants, staff and Peer Navigators. Among participants, there was reduced drug use and an increase in the number of prescriptions for opioid substitution therapy. There were reductions in risky injecting practice and risky sexual behaviour. Participants reported improvements to service engagement and felt more equipped to access services on their own. The lived experience of the Peer Navigators was highlighted as particularly helpful, enabling the development of trusting, authentic and meaningful relationships. The relationship with the Peer Navigator was measured as excellent at baseline and follow-up. Some challenges were experienced in relation to the 'fit' of the intervention within some settings and will inform future studies.

LIMITATIONS

Some participants did not complete the outcome measures, or did not complete both sets, meaning that we do not have baseline and/or follow-up data for all. The standard care data sample sizes make comparison between settings limited.

CONCLUSIONS

A randomised controlled trial is recommended to assess the effectiveness of the Peer Navigator intervention.

FUTURE WORK

A definitive cluster randomised controlled trial should particularly consider setting selection, outcomes and quantitative data collection instruments.

TRIAL REGISTRATION

This trial is registered as ISRCTN15900054.

Peer Recovery Support Services Across the Continuum: In Community, Hospital, Corrections, and Treatment and Recovery Agency Settings - A Narrative Review

In this narrative review, we outline the literature describing the history, training, certification, and role of peer recovery support specialists working with people with substance use disorders at different stages of active use and recovery. We explore the impact of peer recovery support specialists serving people in various settings, including the community, hospitals and emergency departments, jails and prisons, and treatment and recovery agencies; and describes considerations for future expansion of peer recovery support services, including supervision needs, compassion fatigue and burnout, and scope of practice. Finally, we make recommendations to support the broad implementation of peer recovery support services as a sustainable, cohesive, and replicable component of harm reduction and addiction services. We also make recommendations for research to continue to evaluate peer recovery support specialist interventions across settings and outcomes.

"PPI? That sounds like Payment Protection Insurance": Reflections and learning from a substance use and homelessness study Experts by Experience group

BACKGROUND

Patient and Public Involvement in research is important for citizenship, accountability and transparency, and has the practical benefit of helping to ensure its quality and applicability. Involving members of the public in research is becoming increasingly commonplace, in the UK and internationally. It is essential that public involvement is inclusive of individuals and their diverse life experiences, including challenging experiences that may be associated with stigma and social exclusion. The involvement of people with lived/living experience of substance use and homelessness in research is increasing in response to increased recognition of the importance of inclusion and the benefits conferred to research.

MAIN BODY

In this commentary, we share our own experiences of being part of a Patient and Public Involvement group that was convened during a feasibility study of a peer-delivered harm reduction intervention. We are a diverse group but share experience of the field of substance use/homelessness, as people with lived/living experience, and as researchers and practitioners. We share our reflections and learning, as well as offer recommendations for researchers working in our field. Our group worked together to make a positive and deliberate contribution to the study. This did not happen by chance but required the development of mutual trust and respect, with each member having a commitment to support the group for its two-year duration.

SHORT CONCLUSION

It is important for researchers to appreciate that meaningful Patient and Public Involvement is very valuable but requires a commitment from all involved. Regarding our field of substance use and homelessness specifically, it is essential that people with these experiences have opportunities to contribute to research and can do so in a meaningful way. People with lived/living experience are able to bring to life the rich tapestry of others' experiences. However, the involvement must be neither tokenistic nor indifferent to the wider challenges common to these experiences.

Barriers and facilitators to accessing health and social care services for people living in homeless hostels: a qualitative study of the experiences of hostel staff and residents in UK hostels

INTRODUCTION

The number of people living in homeless hostels in the UK has steadily increased over the past decade. Despite people experiencing homelessness often having considerable health problems and a range of complex needs frequently in association with addictions, the experiences of hostel staff and residents especially in relation to accessing health and social care support have seldom been explored. The aim of this paper is to identify the barriers and facilitators to accessing health and social care services for people living in homeless hostels.

DESIGN

Exploratory qualitative baseline data were collected as part of an intervention to facilitate palliative care in-reach into hostels.

SETTING/PARTICIPANTS

Interviews were conducted with 33 participants; 18 homeless hostel managers/support staff and 15 people experiencing homelessness, from six homeless hostels in London and Kent.

RESULTS

Three themes were identified (1) internal and external service barriers to health and social care access due to stigma, lack of communication and information sharing from services and assumptions around capacity and the role of the hostel, (2) the impact of lack of health and social care support on hostel staff leading to burnout, staff going beyond their job role and continuous support given to residents, (3) potential facilitators to health and social care access such in-reach and support from those who understand this population and hostel staff training.

DISCUSSION

Residents have multiple complex needs yet both hostel staff and residents face stigma and barriers accessing support from external services. Positive relationships were described between hostel residents and staff, which can be an essential step in engaging with other services. People experiencing homelessness urgently need better access to person-centred, trauma-informed support ideally via in-reach from people who understand the needs of the population.

"You know, we can change the services to suit the circumstances of what is happening in the world": a rapid case study of the COVID-19 response across city centre homelessness and health services in Edinburgh, Scotland

BACKGROUND

The COVID-19 pandemic has necessitated unprecedented changes in the way that health, social, and housing services are delivered to individuals experiencing homelessness and problem substance use. Protecting those at high risk of infection/transmission, whilst addressing the multiple health and social needs of this group, is of utmost importance. This study aimed to document the impact of the COVID-19 pandemic on individuals who were experiencing homelessness in one city centre in Scotland, and how services adapted in response.

METHODS

Semi-structured interviews were conducted with individuals with lived/living experience of homelessness (n = 10), staff within onethird sector service (n = 5), and external professionals (n = 5), during April-August 2020, using a rapid case study design. These were audio-recorded, fully transcribed, and analysed using Framework. Analysis was informed by inclusion health and equity-orientated approaches to meeting the needs of people with multiple and complex needs, and emerging literature on providing harm reduction in the context of COVID-19.

RESULTS

Those with lived/living experience of homelessness and problem substance use faced a range of additional challenges during the pandemic. Mental health and use of substances were affected, influenced by social isolation and access to services. A range of supports were provided which flexed over the lockdown period, including housing, health and social care, substance use treatment, and harm reduction. As well as documenting the additional risks encountered, findings describe COVID-19 as a 'path-breaking' event that created opportunities to get evidence into action, increase partnership working and communication, to proactively address risks.

CONCLUSIONS

This rapid case study has described the significant impact of the COVID-19 pandemic on a group of people experiencing homelessness and problem substance use within one city centre in Scotland and provides a unique lens on service/professional responses. It concludes with lessons that can inform the international and ongoing response to this pandemic. It is vital to recognise the vision and leadership that has adapted organisational responses in order to reduce harms. We must learn from such successes that were motivated both by compassion and care for those vulnerable to harms and the desire to provide high-quality, evidence-based, harm reduction services.

Provision of peer support at the intersection of homelessness and problem substance use services: a systematic 'state of the art' review

Background

Peer support refers to a process whereby individuals with lived experience of a particular phenomenon provide support to others by explicitly drawing on their personal experience. It has been adopted in a variety of service contexts including homelessness, substance use, mental and physical health. Those who experience homelessness have some of the most complex intersecting health and social challenges. This ‘state of the art’ review provides a systematic search and synthesis of literature examining use of peer support models within services for people impacted by homelessness and problem substance use.

Methods

A systematic search using six databases (CINAHL, SocINDEX, PsycINFO, MEDLINE, Scopus and Web of Knowledge) was conducted in August 2019 and identified 2248 papers published in English after the year 2000. After de-duplication and scanning titles/abstracts, 61 papers were deemed relevant. Three more papers (including one grey literature report) were identified via references, but two papers were later excluded due to relevance. The final 62 papers included studies conducted in five countries. A thematic analysis approach was used to compare and contrast the study findings and provide a synthesis of the main learning points.

Results

In recent years there has been a substantial increase in research examining the utility of peer support yet there is significant variation across this field. Alongside profiling the range of settings, aims, populations, and main outcomes of these studies, this paper also provides an overview of overarching themes: the overall effectiveness and impact of peer-staffed or peer-led interventions; and challenges commonly faced in these roles. Five themes relating to the challenges faced by peers were identified: vulnerability, authenticity, boundaries, stigma, and lack of recognition.

Conclusions

While our findings provide support for current efforts to involve individuals with lived experience in providing peer support to those experiencing concurrent problem substance use and homelessness, they also urge caution because of common pitfalls that can leave those providing the support vulnerable. We conclude that peers should be respected, valued, supported, and compensated for their work which is often profoundly challenging. Suggested guidelines for the implementation of peer involvement in research studies and service delivery are presented.
