Worldwide, over 1.8 billion people lack adequate housing and almost 25% of the world's urban population reside in informal accommodation (United Nations Human Rights Council, 2019). “People with a lived experience of homelessness” is a term coined to describe individuals who are, have been, or at risk of becoming homeless. This population lacks stable, permanent, appropriate housing, or may be without immediate prospect, means and ability to acquire it. Such physical living situations can include emergency shelters or provisional accommodations (Canadian Observatory on Homelessness, 2017). This population continues to grow, giving rise to a major international clinical and public health priority. Homelessness is strongly associated with high levels of morbidity (Hwang, Wilkins, Tjepkema, O'Campo, & Dunn, 2009) and mortality (Nordentoft & Wandall-Holm, 2003). People with lived experience of homelessness are at an increased risk for acute illnesses, such as traumatic injury (including brain injury), frostbite, peripheral vascular disease, soft tissue infections, and dental decay (Hwang & Bugeja, 2000). Many homeless people also suffer from chronic medical conditions, such as diabetes (Hwang & Bugeja, 2000), cardiovascular disease (Lee et al., 2005), cancer (Krakowsky, Gofine, Brown, Danziger, & Knowles, 2013), and respiratory illnesses (Raoult, Foucault, & Brouqui, 2001). Rates of serious mental illness (SMI; Fazel, Geddes, & Kushel, 2014), cognitive impairment (Stergiopoulos et al., 2015) and drug and alcohol use (Aubry, Klodawsky, & Coulombe, 2012; Grinman et al., 2010; Kennedy, Karamouzian, & Kerr, 2017; Kerr et al., 2009; Torchalla, Strehlau, Li, & Krausz, 2011) are disproportionately high, as are rates of homicide and suicide (Cheung & Hwang, 2004). Moreover, people who are homeless experience a disproportionately high prevalence of infectious diseases, such as Hepatitis C, HIV, and tuberculosis (Beijer, Wolf, & Fazel, 2012; Corneil et al., 2006; Roy, Haley, Leclerc, & Boivin, 2001). These conditions are usually not presented as singular or sporadic incidences as many patients who live in an emergency shelter or on the street experience comorbid conditions and illnesses (Lundy, 1999). However, people with lived experience of homelessness are less likely to access and maintain the care required for their cure and treatment (Milloy et al., 2012; Palepu, Milloy, Kerr, Zhang, & Wood, 2011). Despite the disproportionally high burden of acute, chronic, and mental illness, people with lived experience of homelessness encounter many barriers to health and social care. The competing need to find food and shelter results in delays in accessing health-care services (Gelberg, Gallagher, Andersen, & Koegel, 1997). Those who do seek health care often experience discrimination that precludes adequate uptake of preventative health services (Wen, Hudak, & Hwang, 2007), as the structural stigma they experience when accessing health or social services is a major cause of their health inequities (Hatzenbuehler, Phelan, & Link, 2013). For example, people with lived experience of homelessness with coexisting mental health conditions report specific barriers to accessing care, such as being unaware of the location of care, affordability, wait times, and having experienced previous rejection from health or social services (Rosenheck & Lam, 1997). In addition, many health-care recommendations, such as dietary advice, can prove impossible without access to resources such as proper nutrition and cooking facilities (Hwang, 2001). This lack of appropriate access to community-based care and reliable social contexts to implement preventive health behaviors results in disproportionately high acute care use by people with lived experience of homelessness (Saab, Nisenbaum, Dhalla, & Hwang, 2016). This population frequently experiences longer hospital stays and a higher risk of unplanned readmission than the general population (Saab et al., 2016), as discharge planning is compromised by inadequate housing to return to and suboptimal structures to support proper follow-up care (Kushel, 2016). There is substantial research demonstrating that people with lived experience of homelessness benefit from receiving tailored, patient-centered care within interprofessional teams with an integrated approach to community and social services (Coltman et al., 2015; Hwang & Burns, 2014; James, Hwang, & Quantz, 2005). A systematic review on health interventions for marginalized and socially excluded populations identified a range of potentially effective interventions that have relevance for marginalized and excluded populations but was not specific to people with lived experience of homelessness (Luchenski et al., 2017). Additionally, numerous studies have looked at the effectiveness of patient-centered care for people with lived experience of homelessness within community services and social services (Coltman et al., 2015; Hwang & Burns, 2014; James et al., 2005). In order to better understand the needs and resources available for people with lived experience of homelessness, policymakers, practitioners, and allied health professionals need high-quality systematic reviews and knowledge translation strategies on the effectiveness and cost-effectiveness of interventions specific to review to the on the effectiveness and cost-effectiveness of interventions that or the health of with lived experience of the effectiveness and cost-effectiveness of interventions for people with lived experience of homelessness to their health and social of and be in a a & to people with lived experience of homelessness and health-care and with experience in the of homelessness to and needs that are for population et al., 2019). and to a of interventions and to of the to at a and the of the of interventions to be in on of medical practitioners, allied health professionals in of and community with lived experience of homelessness or specific to homeless and and identified as a major priority. are with an of to an interventions and to for a of the from the and the interventions to be in review is as to for a of interventions that not be in and to the effectiveness and cost-effectiveness of interventions people with lived experience of homelessness, is to by housing interventions available for the is a for people who are homeless and with mental illness use to housing et al., many interventions have to people who are homeless and maintain housing et al., 2015; et al., housing the treatment of mental illness or use to the of housing et al., 2016).
