COVID-19 prevalence and infection control measures at homeless shelters and hostels in high-income countries: a scoping review

COVID-19 vaccination of at-risk and marginalised groups: recentering the state in vaccine uptake

Recent studies have used the World Health Organization's new Behavioural and Social Drivers (BeSD) framework to analyse vaccine uptake. However, this study of COVID-19 vaccination among marginalised population groups highlights the framework's limitations regarding the centrality of the state in shaping people's vaccination intentions in high income countries. We conducted interviews and focus groups with service providers and community members to explore COVID-19 vaccination amongst Western Australians experiencing homelessness and/or from other marginalised populations (such as people with substance use dependence). Analysing this data iteratively to emphasise the state's role and functions, we elaborate how trauma and mistrust of government drive thoughts, feelings, and social interactions regarding vaccination programs, which are mutually reinforcing and which inhibit individuals' willingness to engage. Government systems that leave some populations behind increase those populations' susceptibility to misinformation. Policies may generate new unintended problems: social service providers worried about vaccine advocacy damaging clients' trust, especially in the context of vaccine mandates. Reframing the state's responsibility for designing culturally and socially appropriate services, we outline how end-users and trusted providers can lead this process. We share a new framework, "Recentering the State in Vaccine Uptake," arising from our analyses.

The effect of a financial incentive on COVID-19 vaccination uptake, and predictors of uptake, in people experiencing homelessness: A randomized controlled trial

People who are homeless are at increased risk of COVID-19 infection, and of poorer associated outcomes. Delivering vaccinations to, and ensuring uptake of multiple doses in, people who are homeless is complex. Financial incentives may improve vaccination uptake, particularly in people who have not received routine vaccinations previously, though evidence about the effect of incentives is limited and variable. This randomized controlled trial (ANZCTR 383156) assessed the effect of a financial incentive (an A$10 grocery voucher) on uptake of the second COVID-19 vaccination in Australian adults who were homeless, and who had received their first dose. Participants were recruited through a vaccination program for people experiencing homelessness between September 2021 and January 2022. They were followed-up for a minimum of 6.5 months. Uptake was measured 'on-time' at 6 weeks, and at any time during the trial period. Vaccination status was checked on the Australian Immunisation Register. Demographic and vaccination program characteristics associated with uptake were also investigated. Eighty-six people consented to participate, and 43 were randomly allocated to each of the 'incentive' and 'no incentive' groups. The incentive slightly increased the likelihood of a participant receiving a second vaccination on-time (risk difference (RD), 11.6 % [95 %CI, -9.0, 32.2 %]; p = 0.27), and at any time during the trial (RD, 14.0 % [95 %CI, -2.2, 30.1 %], p = 0.09). The incentive had a significant positive effect on uptake in people with no previous vaccination history, increasing their likelihood of receiving a second vaccination on-time (RD, 42.3 % [95 %CI, 15.7, 68.8 %]; p = 0.002) and at any time during the trial (RD, 38.7 % [95 %CI, 16.1, 61.3 %], p < 0.001). Financial incentives may increase COVID-19 vaccination uptake in people who are homeless, and particularly those who have no previous vaccination history. Future research should consider alternative incentive values, types, and cost-effectiveness.

Housing Insecurity and Asthma Outcomes

Asthma is a chronic respiratory disease with widespread prevalence that affects children, adolescents, and adults. Asthma morbidity and mortality can be exacerbated in the setting of housing insecurity. In this Grand Rounds Review article, we present a case and discuss the implications that housing insecurity has on asthma outcomes in the United States. We then highlight ways in which providers can advocate for patients with asthma and housing insecurity.

Homelessness And Health: Factors, Evidence, Innovations That Work, And Policy Recommendations

On a single night in 2023, more than 653,000 people experienced homelessness in the United States. In this overview, we highlight structural and individual risk factors that can lead to homelessness, explore evidence on the relationship between homelessness and health, discuss programmatic and policy innovations, and provide policy recommendations. Health system efforts to address homelessness and improve the health of homeless populations have included interventions such as screening for social needs and medical respite programs. Initiatives using the Housing First approach to permanent supportive housing have a strong track record of success. Health care financing innovations using Medicaid Section 1115 waivers offer promising new approaches to improving health and housing for people experiencing homelessness. To substantially reduce homelessness and its many adverse health impacts, changes are needed to increase the supply of affordable housing for households with very low incomes. Health care providers and systems should leverage their political power to advocate for policies that scale durable, evidence-based solutions to reduce homelessness, including increased funding to expand housing choice vouchers and greater investment in the creation and preservation of affordable housing.

Eviction as a community health exposure

Evidence suggests that being evicted harms health. Largely ignored in the existing literature is the possibility that evictions exert community-level health effects, affecting evicted individuals' social networks and shaping broader community conditions. In this narrative review, we summarize evidence and lay out a theoretical model for eviction as a community health exposure, mediated through four paths: 1) shifting ecologies of infectious disease and health behaviors, 2) disruption of neighborhood social cohesion, 3) strain on social networks, and 4) increasing salience of eviction risk. We describe methods for parsing eviction's individual and contextual effects and discuss implications for causal inference. We conclude by addressing eviction's potentially multilevel consequences for policy advocacy and cost-benefit analyses.
