In this symposium, co-design, implementation and evaluation of the Roundtable will be discussed, including developing medication quality indicators and tailored data presentation formats to facilitate benchmarking and evidence-based action; co-design and trialling an intervention bundle to improve antibiotic use in RAC; processes and outcomes determining the economic costs and feasibility of expansion and sustainability of the Roundtable. Aim: Share insights into the co-design, implementation and evaluation of an Aged Care Medication Roundtable. Activities planned: Linked presentations and interactive session offering perspectives on how routinely collected data can drive improvements in RAC through information sharing, co-design, and shared learning. 1.
