BACKGROUND: Patients from culturally and linguistically diverse (CALD) backgrounds often have unmet healthcare coordination needs. We aimed to evaluate the acceptability, utilisation and perceived benefits of the Mater CALD Health Coordinator Service (M-CHooSe), a pilot, nurse-led, general practice co-located, healthcare coordination service for patients from CALD backgrounds. METHODS: M-CHooSe began in March 2020 at five Brisbane (Queensland) sites. Process and service user data were collected over 12months at one site. A survey evaluated primary healthcare professionals' perceived benefits of the service. Another survey of M-CHooSe nurses examined indicators of service complexity. RESULTS: In total, 206 individuals accessed M-CHooSe over the 12-month period. Commonly delivered services included health service advocacy, chart reviews and health system navigation, including addressing social determinants. M-CHooSe nurses reported frequently performing tasks such as following up with external health services and performing health and social care system coordination. M-CHooSe benefits reported by primary healthcare professionals included better patient access to external health services and improved patient understanding of their conditions and treatments. CONCLUSION: Patients were accepting of referrals to M-CHooSE. Primary healthcare professionals also reported a variety of benefits to themselves and their patients because of M-CHooSe. M-ChooSe highlights the potential of a healthcare coordination service for multicultural patients to improve healthcare equity, accessibility, and system efficiency. This project demonstrates the potential value of coordination services to increase patient access and uptake of existing health and social care services for modern Australian communities, thus improving the efficiency and effectiveness of our health system. Further investigations, including user experience, opinions and cost analyses, will be required to confirm the promising benefits of embedding M-CHooSe into usual care.
