Abstract

Objectives In Canada, individuals experiencing homelessness (IEH) rely on public health and social services for healthcare, food and basic necessities. The COVID-19 pandemic has disproportionately affected marginalised populations, in part by impacting their access to such services. We performed a scoping review to identify from the published literature how access to services has changed for Canadian IEH during the pandemic.

Data sources OVID Medline, Web of Science, Sociological Abstracts, CINAHL and OVID EmCare databases, and websites for the Salvation Army, Homeless Hub, Canadian Alliance to End Homelessness, Canadian Network for the Health and Housing of People Experiencing Homelessness and BC Centre for Disease Control.

Study design We used the scoping review methodology developed by the Joanna Briggs Institute framework and defined access to healthcare and social services using the 10-component Levesque framework. Academic databases and grey literature searches were used, with the final searches for each taking place 24 May and 1 June 2021, respectively. Data were compiled into an Excel spreadsheet. Title and abstract screening and full-text review were completed by two independent reviewers (RG and MM). Data extraction was completed by MM and cross checked by RG.

Results In total, 17 academic and grey literature articles were included. Positive and negative changes in service access were reported in the literature. During the COVID-19 pandemic, access to social and healthcare resources was generally reduced for Canadian IEH. A new component of access, digital connectivity, was identified. Unexpectedly, coordination and collaboration of services improved, as did the number of outreach services.

Conclusions Positive changes to service access such as improved coordination of services should be scaled up. Further work should be done to improve access to digital technologies for IEH.

Strengths and limitations of this study

  • Our study is the first of its kind to synthesise existing literature to examine how the pandemic has impacted access to health and social resources for individuals experiencing homelessness in Canada.

  • Scientific rigour was maintained through the use of a standardised protocol (Systematic Reviews and Meta-Analyses extension for Scoping Reviews), inclusion of a second reviewer and consultation with subject matter experts.

  • Our study used a variety of different databases and grey literature to ensure data capture included perspectives from different fields.

  • Only articles written in the English language were included; this likely excluded relevant literature.

  • Consultation with people with lived and living experience of homelessness was not undertaken in this scoping review and would have aided in contextualising results and adding richness and depth to findings.

Introduction

COVID-19 has had devastating impacts globally, leading to increased morbidity, mortality and unprecedented changes to daily life. Although everyone has been impacted by the pandemic, the homeless population is a particularly vulnerable group that has faced additional challenges and barriers to accessing various healthcare and social services.1 Beyond pandemic conditions, individuals experiencing homelessness (IEH) face disproportionate health inequities relative to the general population.2

‘Homelessness’ is a broad definition describing a variety of sheltering conditions. According to the Canadian Observatory on Homelessness, it encompasses ‘the lack of stable, permanent, appropriate housing or the immediate prospect, means and ability of acquiring it’.3 This review encompassed several typologies of homelessness, including unsheltered homelessness, emergency sheltered homelessness, provisionally accommodated homelessness and those at risk of homelessness.1

Canada’s struggle with homelessness emerged in the 1980s as the result of economic shifts, cuts to social spending, and reduced government investment in affordable housing.4 Over the last 40 years, the number of IEH in Canada has grown, with an estimated 35 000 Canadians facing homelessness on any given night, and at least 235 000 Canadians experiencing homelessness at least once over the course of a single year.4 Unfortunately, Canada’s traditionally reactive approach to homelessness has led to a reliance on services such as emergency shelters to meet the needs of individuals already homeless. While these are essential services, they are ultimately ineffective at reducing the prevalence of homelessness. Despite recent initiatives such as the ‘Housing First’ programme which provides low barrier, permanent housing, homelessness remains a complex and pervasive issue.4

Some subgroups of IEH including youth, Indigenous peoples (including First Nations, Métis and Inuit), those identifying as LGBTQ2S+ (lesbian, gay, bisexual, transgender, queer or questioning and two-sprit) and women face additional unique challenges.4–7 Concerns related to sexual and economic exploitation, trauma, colonialism, criminalisation, racism, stigmatisation and domestic violence disproportionally impact these groups.4–12

Services that are specifically tailored towards subgroups are necessary to account for unique circumstances and identities.10 However, even when services are theoretically available, inequities exist that create barriers to accessing care for these populations, including discrimination and stigma, addiction and mental illness.8 These difficulties are compounded by structural and environmental barriers such as when individuals lack a permanent address or health card and face a paucity of affordable transportation options.3 When individuals are able to access healthcare, gaps and barriers still exist to receiving comprehensive and timely care due to stigma from healthcare professionals, distrust of service providers by IEH and poor coordination of care systems.8 13

In Canada, the Canadian Health Act provides publicly funded healthcare for all citizens, covering all in-hospital care as well as medications (for certain groups).14 Despite this theoretically equal access to ‘free’ care, during COVID-19 IEH were 20 times more likely to be hospitalised from the disease, 10 times more likely to receive care in the intensive care unit and five times more likely to die 3 weeks after receiving a positive COVID-19 test compared with the general population.15

According to Levesque et al, access is the product of dynamic interactions between characteristics of services and characteristics of individuals seeking these services which occur over the process of achieving healthcare. Access can be deconstructed into supply-side features (accessibility) and characteristics of the individual seeking access (ability).16 Accessibility and ability characteristics interface with each other with the potential to produce the outcome of access to a service. This interaction is centred around the steps taken to obtain access, creating a patient-centred framework (figure 1). This accounts for the physical, social and structural environments of access and utilisation of services and provides a means of identifying and mapping facilitators and barriers to healthcare access at each stage of the process.16

COVID-19 has disproportionately affected the health, well-being and daily lives of IEH. With the closure of businesses, services and public areas, it is likely that access to essential resources for IEH has been further altered, but as of yet no formal synthesis of existing literature has examined how COVID-19 has impacted access for IEH across Canada. This scoping review will capture and map the breadth and depth of available literature to understand how the pandemic has affected access to healthcare and social resources for IEH in Canada.

Methods

A scoping review methodology was used based on the Joanna Briggs Institute framework for scoping reviews alongside the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) for reporting findings.17 Both academic and grey literature were examined to ensure comprehensive analysis of the available literature.

Search strategy

Eligibility criteria

Both database searches and grey literature were subjected to the same inclusion criteria. These were as follows:

Inclusion criteria
  • Relates to homeless individuals and COVID-19 and health or social resource access.

  • Research focus includes a region within Canada (either exclusively or in comparison with another jurisdiction).

  • Article is written in English.

  • Articles published from 1 January 2020 onwards will be considered, with the final database search taking place on 24 May 2021, and the final grey literature search taking place 1 June 2021.

The search strategy and review protocol (unpublished) were iteratively developed alongside the input from a Health Science librarian from McMaster University. Iterations included refining which databases and subject headings to utilise. OVID Medline, Web of Science, Sociological Abstracts, CINAHL and OVID EmCare were used to obtain academic literature using the subject headings of (COVID-19) AND (Canada) AND (Homeless persons). Subject headings and Boolean operators were adjusted as necessary for each database. The final database search was run on 24 May 2021 (see online supplemental figure 1 for OVID Medline database search strategy). Two reviewers (MM and RG) independently completed title and abstract screening and full-text review; one reviewer (MM) completed citation chaining. All articles were cross checked by RG during title and abstract screening, full-text review and data extraction using the predetermined inclusion criteria. Disagreement regarding the inclusion of articles was resolved through discussion between MM and RG over a Zoom meeting, which ultimately resulted in consensus. The involvement of a third individual was not necessary as no instances occurred in which consensus was unattainable.

The protocol by Godin et al was used to identify grey literature sources and included advanced Google searches in combination with targeted website searches. The Salvation Army, Homeless Hub, Canadian Alliance to End Homelessness, Canadian Network for the Health and Housing of People Experiencing Homelessness and the BC Centre for Disease Control were used in targeted website searches.18 Due to the variability of grey literature as noted by Godin et al, search terms used previously in academic database searches often did not return results and were, therefore, adapted to five key terms capturing the core concepts of the study- COVID-19*, homeless*, social, health* and Canada. These were used for advanced google searches and targeted website searches. The final grey literature search was completed on 1 June 2021. In accordance with the protocol by Godin et al, title and abstract screening for grey literature was completed by one reviewer (MM). Expert consultation was completed with subject matter expert JAB (expert in harm reduction and public health) regarding current barriers to accessing healthcare and social services for IEH in Canada, and how this aligned with the research findings from the present study. JAB also provided guidance regarding websites to be included for grey literature searches.

Data extraction

All data extraction was entered in an Excel spreadsheet which was collaboratively developed by MM, RG and JAB with the assistance of a science librarian. Information pertaining to the 10 components of the Levesque framework was extracted. Other spreadsheet components included the articles’ citation, type of article, methods used, geographic area and population of focus, useful quotes, additional information and aspects of access not addressed by the Levesque framework. During extraction, data regarding digital connectivity was repeatedly seen in the literature. Consultation among authors led to consensus that this was a novel component of access not previously captured by Levesque et al and, thus, it was included as a separate, novel category for data extraction. MM completed data extraction using the Excel sheet. Independent reviewer RG then reviewed all included articles and cross-checked information. Any disagreement regarding final inclusion of data was resolved through discussion over a Zoom meeting, with consensus being met in all cases and the inclusion of a third reviewer not necessary. The intent of the present scoping review is to provide a clear indication of the volume of current literature and describe the literature available on the subject. In accordance with the definition of a scoping review by Munn et al, a critical appraisal is beyond the scope of this methodology, as the aim is rather to map what literature currently exists on this emerging health issue.19 Critical appraisal (steps 12 and 16) of the PRISMA-ScR checklist was, therefore, not conducted. In total, 17 articles were included.

Synthesis

For the 17 articles included in the scoping review, a table was created (table 1) to synthesise and compare the articles based on the type of study and methodology. This table also features the region and population of focus and components of the Levesque framework included in the article. This helps to identify what components are included in which articles as well as where data tend to focus in terms of geography and population. Figure 2 provides an overview of the selection process that produced the 17 articles used in this review. Using the extracted data related to the 10 components of the Levesque framework and the novel category of digital connectivity, themes regarding how access has changed were identified (ie, if access improved or worsened, and how) based on recurring findings from the literature within each category of data collected. These findings were synthesised and summarised in table 2. In the discussion, the interaction between components of access is further described. Some of the characteristics identified in the articles were then translated to a graph (figure 3) to visually represent the number of articles that address each of the accessibility and ability characteristics of the Levesque framework as well as the novel category of digital connectivity.

Results

Overview

Two searches were run using the scholarly databases, with the final search on 24 May 2021. In total, 257 articles were imported for screening; 107 were removed as duplicates leaving 150 articles for title and abstract screening. Of these, 105 were deemed irrelevant by both reviewers, leaving 45 articles for full-text review. This process yielded 33 additional exclusions that were agreed on and recorded by both reviewers. The most common reasons for exclusion were ‘wrong study design’ or ‘does not assess access’ (both n=17). In total, 12 articles were included for data extraction. Citation chaining produced eight additional articles, none of which fits the inclusion criteria and was excluded after independent review by MM and RG.

In total, 73 grey literature articles were identified, with the last grey literature search completed on 1 June. Nine duplicates were removed, leaving 64 articles for title and abstract screening. During title and abstract screening, an additional 39 articles were removed, leaving 25 articles for full-text screening. During screening, additional articles were removed for not assessing access (n=10) and wrong study design (n=5). Ultimately, 10 articles from the grey literature were included for extraction, leading to a cumulative 22 articles for extraction.

During extraction, reviewers independently agreed on the removal of an additional five articles, for reasons of: duplication (n=1), not assessing access (n=3) and failure to address COVID-19 expansively (n=1). In total, 17 articles were included in analysis, eight from grey literature and nine from academic databases (figure 2). Included articles were primarily qualitative in nature (n=10), with some including quantitative (n=4) and mixed-method (n=3) designs (table 1). In terms of geography of focus, eight articles examined Canada broadly, five were Ontario-specific (primarily focused on the Greater Toronto Area), three were specific to BC (mainly focusing on the Vancouver area), and one was focused in Alberta. All articles pertained to the experiences of IEH in Canada, however, the specific population of focus varied. Women and girls were highlighted in two articles, as were youth and service providers. The remaining articles (n=11) pertained to the experiences of IEH more generally.

In terms of the 10 characteristics of access defined by Levesque, accessibility criteria were identified in more of the articles than ability criteria (figure 3). ‘Availability and accommodation’ and ‘appropriateness’ were categories most frequently identified (n=16, n=15, respectively). Approachability was noted in 11 articles, and acceptability and affordability were each mentioned in six articles. Criteria relating to ‘ability’ were less frequently identified in the literature. Content regarding the ability to perceive and to seek healthcare were each found in four articles, ability to engage was identified in five while the ability to reach and the ability to pay were each identified in six articles. A new category, digital connectivity was identified and agreed on by both reviewers during the data extraction process. This dimension was found in five articles but did not fit into the Levesque framework categories. An overview of included articles is found in table 1.

Themes

Data were compiled into 11 themes, the first 10 falling under the components of the Levesque framework (figure 1). Digital connectivity was also identified as a recurring finding and is not accounted for by the Levesque framework. Because of this, ‘digital connectivity’ was added as an 11th category and analysed separately given its cross-cutting nature. As a result of the interconnectedness inherent to access as posed by the Levesque framework, the themes identified under each ‘pair’ of accessibility and ability criteria are analysed together (table 2).16

Approachability and ability to perceive

Overall, although outreach was expanded during the pandemic, communication was ineffective and inadequate (approachability), and health literacy and trust in the system relating to COVID-19 messaging was low (ability to perceive). Outreach initiatives such as provision of naloxone20 and mobile COVID-19 testing improved during the pandemic; however, information regarding public health mandates was found to be unclear,21 lacked timeliness and/or was inaccessible due to language barriers.1 22 23 This contributed to poorer health literacy24 and reduced trust in the system for youth in particular.20 21

Acceptability and ability to seek

In general, services offered during the pandemic were deemed unacceptable (acceptability) and help-seeking behaviours were reduced (ability to seek). A lack of appropriate services for vulnerable groups (youth, LGBTQ2S+, and Indigenous groups) was problematic and contributed to disconnection from communities.25 Youth in particular found virtual services to be unsafe and unacceptable.26 Preference for face to face services may have reduced help-seeking behaviour,20 and viewing services like shelters as unacceptable may have led individuals to choose to sleep outside (ability to Seek).21

Availability and accommodation and ability to reach

Service closures reduced service availability, despite many initiatives enacted to meet the immediate needs of IEH, including provision of hotels to increase shelter spaces, temporary washrooms and hygiene spaces, and on-site shelter COVID-19 testing (availability and accommodation).1 20–23 25–34 While there were increased outreach services, it was generally difficult to access resources due to reductions in transportation and the transient lifestyles of many IEH (ability to reach). This was especially true for those living in rural areas.20 24

Affordability and ability to pay

Emergency response funding increased during the pandemic for IEH at federal and provincial levels, and low-cost or free harm reduction initiatives were implemented.20 26 29 34 Despite this, housing affordability remains a primary issue for those who are precariously housed (affordability).21 22 Women were disproportionately affected by job losses during the pandemic and have been slower to recoup financial losses and regain employment (ability to pay).23 26 33

Appropriateness and ability to engage

Despite service closures, collaboration between stakeholders and continuity of services was improved, as seen by reduced service duplication, fewer IEH being discharged into homelessness and increased emergency shelter spaces.20 22 27 31 32 35 However, the quality of services (in particular, emergency shelters) was deemed poor (appropriateness).1 21 23 24 30 Overall, IEH readily engaged in their care when given the opportunity, but poor quality of care, mental illness and substance use made engagement more difficult (ability to engage).1 25 28 34

Digital connectivity

Digital connectivity was identified as a novel category relating to access in pandemic times for IEH. Access to a mobile phone, phone plan, internet and safe spaces to engage in virtual care were problematic barriers for IEH, with inability to afford digital technology or internet precluding engagement in virtual services.20 21 25 26 35

Discussion

Summary of findings

During the COVID-19 pandemic, access to social and healthcare resources was generally reduced for Canadian IEH. While each component of access can be placed into discrete categories, in reality, they interact in complex ways.16 Furthermore, while the present search was restricted to examining access to services for IEH in Canada during the COVID-19 pandemic, inequitable health outcomes flow from disparate access to resources, and, thus, such outcomes are briefly described in relation to the results.

Barriers in receiving, understanding and ultimately taking action to apply new public health directives impeded COVID-19-related health literacy among IEH during the pandemic, largely due to a lack of digital connectivity and language barriers. This resulted in disengagement with services as well as reduced trust in health and social care systems, particularly for youth experiencing homelessness (themes: approachability, ability to perceive)20–22 24–28 This contributed to reduced service-seeking behaviours (particularly among youth) (ability to seek).25 26 Even if public health messaging was received and understood in a timely manner, messages to isolate, practice-enhanced hygiene and physically distance from others were based on the incorrect assumption that every person receiving such messaging had the assets and capacity to adapt to these new protocols.22 23

Service closures compounded self-reported feelings of isolation,25 with qualitative data indicating that feelings of isolation and loneliness worsened youth’s mental health. This, in turn, increased substance use (despite an increasingly toxic supply), which can exacerbate difficulties in achieving access to care and worsen pre-existing mental health challenges.20 26

Additionally, during the pandemic, a lack of culturally appropriate and safe services for Indigenous, LGBTQ2S+ and ethnic individuals contributed to increased feelings of isolation, disconnection and worsened mental health due to being cut-off from social and cultural networks (themes: acceptability, appropriateness).20 25 It is possible that health impacts were exacerbated as a result of disconnection from culturally appropriate religious practices such as traditional healings. Other additionally vulnerable groups including women and youth also faced increased hardships and barriers to accessing services. During the pandemic, gender-based violence has increased both globally and within Canada.33 36 Because domestic and gender-based violence is often a precursor to women’s homelessness, more women may be pushed into homelessness as a result. Conversely, in an attempt to maintain health, women and youth may choose to move back into housing that is unsafe. This puts women and youth, and especially LGBTQ2S+youth, at increased risk of violence, exploitation and abuse, negatively impacting physical, mental and social health.20 21 23

Shelter spaces (especially those that serve women) are typically underfunded and face rapid staff turnover (theme: availability).28 33 During the pandemic, the need to reduce overcrowding and enhance physical distancing, as well as greater staff turnover, exacerbated limitations on shelter infrastructure and human resources.1 24 28 32 Even if shelters were available, many IEH deemed them inadequate due to overcrowding and concerns of contracting COVID-19, sparking the creation of tent cities and encampments (themes: acceptability accommodation). This contributed to poor nutrition, exposure to the elements and reduced access to clean water.23

Stigma towards women and youth has also led to difficulty in obtaining housing. With eviction prevention measures implemented during the pandemic, landlords are reportedly unwilling to rent to youth because of feared income loss should youth be unable to pay for living spaces and cannot be evicted.21 Financially, women have experienced disproportionate job losses and longer waits to be rehired during the pandemic (themes: affordability, ability to pay). Coupled with school and childcare service closures and embedded gender norms dictating that women are responsible for childcare, women have encountered additional barriers to obtaining and maintaining employment, with some turning to sex work.21 Opportunities like resume building, interview training and volunteer experiences to improve employability have been reduced due to closure of services.21 Considering the gendered and age-specific needs of these groups, it is necessary to alleviate additional barriers to accessing social resources such as employment and housing services.

Finally, the pivot to offering services virtually was a departure from how services have historically been delivered (themes: ability to engage, digital connectivity). While this benefited those in rural areas by reducing transport-related barriers, it was a barrier for those lacking the financial means to obtain a phone, phone plan and/or internet (themes: ability to reach, digital connectivity).26 This was especially true for youth.20 Not only is the cost of digital technology prohibitively expensive for many IEH but finding a safe space in which to participate in appointments can also be problematic. Government initiatives meant to engage the public in health promotion in low-barrier ways, such as the COVID-19 Alert App, were barriers, rather than facilitators, for IEH in accessing healthcare information.35 Together, the multiple reductions in access to services indicate a lack of inclusion of IEH in programme and policy development, resulting in misinformed and misaligned programmes that are exclusionary to those most in need of support.

While access to services has been reduced in many ways, positive changes should not be ignored. Expansion of outreach initiatives designed to provide daily necessities like transportation options, on-site COVID-19 testing at shelters, washrooms, showers, food, harm reduction and temporary housing in motels and hotels were critical in maintaining the well-being of IEH (themes: approachability, accommodation).20 22 27 29–32 34 Increases in funding federally and provincially for the homeless service sector allowed outreach programmes to be initiated and maintained.20 Financial barriers to services were dismantled in numerous ways, such as making COVID-19 testing free and allocating funds to low-income individuals.29 Finally, in some instances, coordination between organisations, the community and government improved, which lead to streamlining of the system, better partnership and engagement with clients, and fewer IEH falling through system ‘gaps’.20 21 25 27 31 32 34

Contextualising Canadian homelessness to facilitate change

COVID-19 has exacerbated and illuminated cracks in the current healthcare and social service system.30 The disparate health outcomes IEH experience are not solely attributable to the pandemic but are downstream products of broad upstream factors, including a lack of affordable housing, colonialism and associated stigma and discrimination. Clearly, improving access is not enough to eliminate the disproportionate poor health outcomes of IEH populations.

Racism, stigma and discrimination are key factors intimately linked with homelessness. Colonialism of Indigenous peoples is a structural determinant of health initiating and perpetuating homelessness in Canada, which has affected Indigenous peoples spiritually, emotionally, physically and mentally37 and has led to disproportionate representation of Indigenous peoples in Canada’s homeless population.9 The present study found that Indigenous peoples have faced disconnection from social and cultural networks related to a lack of culturally appropriate and safe services.20 25 While the pandemic has undoubtedly exacerbated feelings of isolation and barriers to accessing appropriate services for Indigenous peoples, these are systemic issues, and this disconnection to culturally safe care is a product of long-standing and ongoing colonial forces in Canada.

Stigmatisation and discrimination are additional structural inequities that can manifest in the criminalisation of homelessness, which creates a vicious cycle of incarceration and discharge back into homelessness.38 In Canada, during the COVID-19 pandemic, those without a home could be fined ($500-$10 000 CAD) for failure to follow physical distancing orders, despite lacking permanent, safe and adequate shelter or places to remain distant.1 Furthermore, prior to the COVID-19 pandemic, IEH experienced reduced access to quality care due to discrimination, stigma and distrust of service providers in combination with structural barriers.3 8 13 Issues with transportation, inability to access digital care, poor communication of information and distrust in the healthcare system were identified in this review as key barriers to accessing resources for IEH during the pandemic.20 22–26 35 While the pandemic may have augmented such barriers, they are not novel.

Entry into and perpetuation of homelessness is largely facilitated by structural factors.39 Contextualising drivers of homelessness is necessary in facilitating its resolution. Historically, Canada’s cuts to social spending have led to increased homelessness and a reduced social safety net, contributing to housing unaffordability.4 The findings of this review highlight the ways in which the pandemic has exacerbated this, particularly for additionally marginalised groups such as women who faced disproportionate job losses and difficulty obtaining housing.21 23 26 33 This has the potential to compound negative health outcomes as individuals may opt to live in unsafe environments.20 21 23 The precarity of maintaining housing that is appropriate and affordable must, therefore, be addressed to prevent the transition into homelessness. In Canada, increased investments in affordable housing and supports for IEH are needed, and work must be done to empower and partner with individuals, particularly those holding additional vulnerable identities, to identify and implement appropriate solutions. Partnering with individuals with lived and living experience of homelessness can provide insights that lead to policy and programme change that is more effective and sustainable.40 Thus, partnership can help politicians and programme developers not to ‘miss the mark’ when creating interventions.

Strengths and limitations

The use of a standardised protocol (PRISMA-ScR), inclusion of a second reviewer and consultation with subject matter experts contributed to the scientific rigour of this review. Additionally, our study used a variety of databases and search strategies as detailed above. This allowed for enhanced capture of diverse perspectives from many fields. This review would have benefitted from consultation and engagement with people with lived and living experience of homelessness to contextualise study findings and ensure results capture lived experiences of those impacted by homelessness in its many forms. Literature included in this scoping review pertains only to the Canadian context, which likely limits generalisability.

Comparison with previous research

While it should be recognised that the pandemic has had global impacts, addressing such effects is out of scope in this review. To date, there exists no globally agreed upon definition of homelessness.41 42 In addition, countries have different approaches to managing homelessness and have responded to the pandemic in different ways.43 44 Because of the lack of shared language and various approaches to responding to the pandemic, the current review has focused on Canada. This may improve internal validity of the findings, while still providing a level of application and generalisability to countries with similar healthcare and social infrastructures, and common socioeconomic and political contexts driving and perpetuating homelessness.

While a comparison to the broader literature is not included in this study, it should be noted that the current findings align with those provided by Nouri et al who highlight four factors that led to increased vulnerability for IEH during the COVID-19 pandemic. These include personal, lifestyle, social and managerial factors. Within these categories on an international scale, social isolation and stigma, lack of housing, shutdown of services and a lack of technology all contributed to reduced access to care for IEH, leading to vulnerabilities in this population.45 Likewise, findings from this review concur with a recent Canadian rapid review conducted by Oudshoorn et al where authors noted that IEH are uniquely vulnerable to COVID-19. Governmental actions were found to be inconsistent in addressing the unique needs of people experiencing homelessness and authors noted that despite pandemic response efforts, there is little evidence that broader strategic housing approaches are being considered.46 Findings from the current review indicate that increased capacity was limited to emergency shelter sites, but long-term, sustainable housing supports remain underexplored.1 Both Nouri et al and Oudhoorn et al highlight inadequate housing as a core issue to address.45 46

Understanding that IEH experienced reduced access to services during the pandemic is insufficient to create positive change. As seen in this review, it is important to consider the concept of access in all its forms, and to recognise both gaps in access and positive changes seen during the COVID-19 pandemic to facilitate positive policy change and programme refinement in the future.

Directions for future research

Further investigation must be done to better understand how social, economic, and political factors intersect and uniquely impact IEH both during the pandemic and outside of pandemic conditions. Inclusion of marginalised groups is an important component of research and policy development in order to enact better informed, relevant and sustained change while promoting collaboration among stakeholders.40 As such, the inclusion of people with lived and living experience of homelessness in all future research activities is essential. Already, policy and research regarding illegal drug use is being informed by people with lived and living experience, who are seen as experts in their own right.47 Likewise, involving those who have experienced homelessness in research and policy development may provide an opportunity to gain valuable insights into the lived realities of IEH during the pandemic. In addition, literature indicates that IEH have different perspectives from service providers about factors that facilitate engagement with services.48 Authentic partnership may potentiate the ability to address root causes of inequity, rather than responding to down stream outcomes of stigmatisation and disparity. Overall, responses to homelessness were not seen as acceptable or appropriate to IEH during the pandemic.1 21 23 24 26 30 By including people with lived and living experience of homelessness in future planning, it is possible that the disproportionate reductions in access seen during the COVID-pandemic can be avoided in the future.

Additionally, the emergence of a novel component of access, digital connectivity, warrants further investigation. Given accelerating technological innovation as well as pandemic-related shifts to virtual care and services, reducing disparities in access to digital mediums should be a public health and policy priority.

Finally, it may be beneficial for future research to compare pandemic responses and issues of access to health and social resources for IEH during COVID-19 on a global scale.

Conclusion

During the COVID-19 pandemic, access to social and healthcare resources was generally reduced for IEH. Clearly, barriers and facilitators to access are tied to stigmatisation, discrimination and marginalisation. Despite the exacerbated barriers to accessing services driven by COVID-19, some positive changes were seen. Collaboration and coordination of services improved, as did the number of outreach services and temporary accommodations. Such interventions should be scaled up locally, provincially and nationally, with collaboration between stakeholders (including people with lived and living experience of homelessness) to facilitate a coordinated approach to improve resource access now, and to ensure continuity after the pandemic.

Digital connectivity was a novel category related to access and was not previously identified in the Levesque framework. This demonstrates that the dimensions of access are changing with the expansion of technology, creating new forms of inequity. Work should be done to support improvements in access to cellphones and internet for IEH, which may have a positive impact on their ability to access health and social services.

Homelessness is driven by social, political, and economic factors. There is a need to contextualise homelessness in order to address upstream causes, rather than maintain a singular focus on downstream outcomes. The disparities experienced by IEH seen in the current review are not novel; the pandemic has merely exacerbated and illuminated existing inequities. Addressing these foundational issues in collaboration with people with lived and living experience of homelessness may have a significant impact on reducing disparate access to healthcare and social resources experienced by IEH both now and in future crises.
