BACKGROUND People experiencing homelessness (PEH) have poorer physical and mental health than the general population. They are also more likely to have less access to healthcare. These processes of access can be better understood using Levesque's access framework which addresses both supply (service provision) and demand (user abilities).

METHODS Following the Joanna Briggs Institute (JBI) guidelines, electronic peer-reviewed databases were searched in February 2022 for studies published since 2000 related to access to healthcare for PEH ages 16 and older in the United Kingdom (UK) and Ireland. Retrieved articles were screened and those eligible were selected for data extraction. Qualitative and quantitative studies were included.

RESULTS Fifty-six papers out of 538 identified were selected and aliased. Six main themes were identified: staff education, flexibility of systems, service coordination, patient preparedness, complex health needs and holistic care. These relate to the Levesque access framework.

CONCLUSIONS Improving access to healthcare for PEH requires changes to how services are provided and how service-user abilities are supported.
