Access to cancer preventive care and program considerations for people experiencing homelessness across four European countries: an exploratory qualitative study

BACKGROUND: People experiencing homelessness (PEH) have a higher prevalence of adverse health outcomes and premature mortality compared to the non-homeless population. These include a higher burden of cancer and cancer-specific morbidity and mortality—outcomes that may be a consequence of significant barriers to accessing primary and secondary prevention and community health services. This study aimed to better comprehend the health needs and barriers to accessing preventive cancer care for PEH across four European countries as well as necessary considerations for developing interventions around cancer prevention for this population. METHODS: In this exploratory qualitative study, 69 semi-structured interviews were conducted across Austria, Greece, Spain, and the UK, with a sample comprising 15 professionals working in homelessness support services, 19 health professionals, and 35 PEH. Interviews took place between August 1 and October 31, 2021, and data were analysed inductively and iteratively following a thematic approach. FINDINGS: Findings were organised into two overarching themes: (1) Experiences and understanding of cancer prevention and treatment and (2) Considerations for program interventions. While cancer was a significant worry among PEH across all settings, they generally had minimal knowledge and understanding of cancer symptoms and prevention. Specific programs for cancer prevention for PEH were described as almost non-existent. Health professionals in some settings indicated that cancer in PEH was often missed in the early stages and instead diagnosed when the severity of symptoms intensified. INTERPRETATION: Overall, our findings indicate many commonalities in the health needs of PEH and the barriers they face when they seek access to cancer-specific healthcare services in the European context. FUNDING: This study received funding from the 10.13039/501100007601European Union’s Horizon 2020 Research and Innovation Programme under GA 965351.
