Evaluating Age-Friendly Health Care Approaches in Rural Primary Care Settings: A Multi-Case, Mixed-Methods Hybrid Type 2 Effectiveness-Implementation Study

Maintaining and improving the health and well-being of older people in rural communities through integrated care is essential to address this cohort's frailty risk. The Indigo 4Ms Tool for health workers is a rural-specific approach to providing care that addresses the common conditions of ageing. With Australian government funding, five small rural health services are implementing the tool. This paper describes the protocol for a hybrid type 2 implementation-effectiveness study to evaluate the tool's impact on multidisciplinary comprehensive care planning and the implementation strategies that enhance the adoption and sustainability of the tool across diverse rural health settings.
