PURPOSE: This study aimed to explore health professionals' perspectives regarding the presence, assessment and management of risks when providing community-based rehabilitation (CBR) to clients with acquired brain injury (ABI). METHOD: A qualitative approach using semi-structured interviews of health professionals working in CBR. RESULTS: The main themes were: (1) risk assessment in CBR settings is an informal, unstructured, complex, multi-phase and cyclical process extending over a period of time; (2) structured and standardised risk assessments were not considered ideal for use in CBR services catering for people with ABI; (3) CBR services face numerous challenges in providing effective risk assessment and management; (4) the risks encountered by health professionals in CBR settings are not always predictable or preventable; and (5) CBR risk management focuses on implementing a range of practical strategies. CONCLUSIONS: A flexible risk assessment process supported by a range of practical risk management strategies to minimise and manage potential risks is advocated by health professionals working in CBR services for people with ABI. There is a need for more research into the effectiveness of current risk assessment and management strategies for CBR services.
