The population is aging, with frailty emerging as a significant risk factor for poor outcomes for older people who become acutely ill. We describe the development and implementation of the Frail Older Persons' Collaborative Program, which aims to optimise the care of frail older adults across healthcare systems in Queensland. Priority areas were identified at a co-design workshop involving key stakeholders, including consumers, multidisciplinary clinicians, senior Queensland Health staff and representatives from community providers and residential aged care facilities. Locally developed, evidence-based interventions were selected by workshop participants for each priority area: a Residential Aged Care Facility acute care Support Service (RaSS); improved early identification and management of frail older persons presenting to hospital emergency departments (GEDI); optimisation of inpatient care (Eat Walk Engage); and enhancement of advance care planning. These interventions have been implemented across metropolitan and regional areas, and their impact is currently being evaluated through process measures and system-level outcomes. In this narrative paper, we conceptualise the healthcare organisation as a complex adaptive system to explain some of the difficulties in achieving change within a diverse and dynamic healthcare environment. The Frail Older Persons' Collaborative Program demonstrates that translating research into practice and effecting change can occur rapidly and at scale if clinician commitment, high-level leadership, and adequate resources are forthcoming.
