Introduction: The Carer Support Unit (CSU) of the Central Coast Local Health District (CCLHD), NSW, Australia, developed, trialled and implemented a Carer Readiness Tool (CRT) to help carers gauge their readiness to care at home, highlight to hospital staff areas for additional support for carers, and provide evidence of carer engagement in discharge planning. Methods: A rigorous co-design process was followed with carer consultation at key milestones in development of the CRT.
