Post-diagnosis young onset dementia (YOD) care is often fragmented, with services delivered across aged care, health care, and social care sectors. The aim of this project was to test the feasibility and effectiveness of a learning collaborative implementation strategy for improving the cross-sector integration of care for people with YOD.

We conducted a longitudinal mixed-methods process evaluation, and recruited one representative from three Australian aged care organisations, three disability care organisations, and three organisations contracted to deliver care navigation services. One representative from each organisation joined a learning collaborative within their local area and completed a six-module online education package incorporating written resources, webinars, collaboration, and expert mentoring. Participants identified gaps in services in their region and barriers to care integration, and developed a shared plan to implement change. Normalisation Process Theory was applied to understand acceptability, penetration, and sustainability of the implementation strategy, as well as barriers and enabling factors.

Dementia knowledge measured by the Dementia Knowledge and Awareness Scale was high among the professionals at the start of the implementation period (Mean = 39.67, standard deviation = 9.84) and did not change by the end (Mean=39.67, standard deviation = 8.23). Quantitative data demonstrated that clinicians dedicated on average half of the recommended time commitment to the project. However, qualitative data identified that the learning collaborative strategy enhanced commitment to implementing integrated care and promoted action toward integrating previously disparate care services. Participant commitment to the project was influenced by their sense of obligation to their team, and teams that established clear expectations and communication strategies early were able to collaborate and use the implementation plan more effectively (demonstrating collective action). Teams were less likely to engage in the collective action or reflexive monitoring required to improve care integration if they did not feel engaged with their learning collaborative.

Learning collaboratives hold promise as a strategy to improve cross-sector service collaboration for people with YOD and their families but must maximise group cohesion and shared commitment to change.
