Background and Aim: CoPs are currently promoted by government and professional bodies in Australia as a way to support staff development and practice change in aged care. CoPs can be a powerful change mechanism. They are regularly written about; however, key details are often obscure on how a group is facilitated, who participates, key activities or outcomes. This negatively impacts learning what supports CoP function and impedes drawing on other’s experiences for planning or evaluation. This project aimed to develop a CoP Reporting Guide to foster a shared understanding of CoPs, and to encourage consistent and comprehensive description of CoPs in research and practice. Method: Real Time Delphi (RTD) consensus study with supplementary qualitative questions and thematic analysis. Open questions and 47-item set presented in an 8-week RTD process using the Calibrum® system and a priori 70% agreement rate. Results: Participants were 37 international CoP subject experts across diverse domains (eg: health/aged care, tertiary education, government, business). Survey question completion rate ranged from 76% - 92%. Delphi voting resulted in two main categories for the Guide – 10 Core items relevant to all CoPs (eg: purpose, value, community) and 37 Extended items reflecting greater depth and breadth for different contexts (eg: governance, resources, evaluation, frameworks). Implications: The Delphi study underpins a CoP Reporting Guide to aid researchers and practitioners to define, describe, and write more clearly about CoPs. Improving our shared understanding of CoPs supports application and innovation in aged care practice and research. This presentation will share the RTD process and the Guide, enhancing our collective wisdom on CoPs.
