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 12 months 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. People with multicultural or refugee backgrounds are more likely to have poorer long-term health outcomes compared to natively born people, and experience barriers accessing health care. We piloted a multicultural healthcare coordinator service and demonstrated that it was acceptable to patients and primary healthcare practitioners, well-utilised and demonstrated good outcomes. The service has the potential to reduce healthcare inequities if implemented into ongoing primary care services. [ABSTRACT FROM AUTHOR]

The induction of persistent protective levels of pathogen-specific antibody is an important goal of immunization against childhood infections. However, antibody persistence is poor after immunization in infancy versus later in life. Serogroup C meningococci (MenC) are an important cause of bacteraemia and meningitis in children. The use of protein–polysaccharide conjugate vaccines against MenC has been associated with a significant decline in the incidence of invasive disease. However, vaccine effectiveness is negligible by more than 1 year after a three-dose priming series in infancy and corresponds to a rapid decline in antibody following an initial immune response. The cellular mechanisms underlying the generation of persistent antibody in this age group are unclear. An essential prelude to larger studies of peripheral blood B cells is an understanding of B-cell kinetics following immunization. We measured MenC- and diphtheria-specific plasma and memory B-cell kinetics in infants receiving a CRM197 (cross-reactive material; mutant diphtheria toxoid)-conjugated MenC vaccine at 2, 3 and 4 months of age. Plasma cell responses were more delayed after the first dose when compared with the rapid appearance of plasma cells after the third dose. Memory B cells were detectable at all time-points following the third dose as opposed to the low frequency seen following a first dose. This study provides data on B-cell kinetics following a primary schedule of immunization in young infants upon which to base further studies of the underlying cellular mechanism of humoral immunity.
