People with an acquired brain injury (ABI) experience substantial access inequalities and unmet health needs, with many experiencing insufficient access to appropriate rehabilitation in the community. To deepen our understanding of what appropriate access to post-acute care services is for this population, and to facilitate optimal recovery, there is a need to synthesise research from the service user perspective. A scoping review study was conducted to identify key characteristics of ‘appropriate’ access to post-acute care services, as defined by the personal experiences of adults with ABI. Electronic scientific databases Medline, PsycINFO, Proquest Central and CINAHL were searched for studies published between 2000 and 2020. The initial search identified 361 articles which, along with articles retrieved from reference list searches, resulted in 52 articles included in the final analysis. Results indicated that a majority of the studies sampled participants with an average of over 1 year post-injury, with some studies sampling participants ranging over 10 years in difference in time post-injury. A thematic synthesis was conducted and results indicated a number of dominant elements which relate to (1) the characteristics of services: provider expertise, interpersonal qualities, partnership and adaptability; (2) characteristics of the health system: navigable system, integrated care, adequacy, and opportunity. These findings provide some insight into what might be considered appropriate. However, rigorous research, focused on personalised access to post-acute care services, is recommended to verify and elaborate on these findings.
