PURPOSE OF REVIEW: This review seeks to identify the current prevalence of potentially life-limiting respiratory conditions among those who have experienced homelessness, incarceration or had criminal justice involvement, and current developments in, and barriers to, delivery of supportive and palliative respiratory care to these populations. These structurally vulnerable populations are known to be growing, their health behaviours more risky, and their morbidity and mortality higher, with evidence of accelerated ageing. RECENT FINDINGS: Most studies identified investigated prevalence of respiratory conditions, which were found to be high. In contrast, only one study directly explored supportive and palliative care (in a prison population) and none considered or addressed palliative and end-of-life needs of these populations, or mechanisms to address them. There was an absence of qualitative work and studies of the impact on, or role of, family, friends or informal networks. SUMMARY: There is a need for evidence-based interventions to reduce the risk of communicable respiratory conditions and a greater understanding of disease trajectories and management for these vulnerable populations, including provision of accessible appropriate supportive, palliative and end-of-life care.
