Abstract

Objectives
There is an increasing need to engage with evidence-based practice (EBP) and continuing professional development (CPD) to effectively respond to the current healthcare demands and challenges. This review critically synthesises key knowledge diffusion and implementation theories, with particular emphasis on Communities of Practice (CoPs), a theory as yet unexplored in radiography practice.
Key findings
Prominent theories including implementation science, translational science and knowledge diffusion theories have previously been proposed to bridge the theory-practice gap. However, the radiography profession is a fast-paced, complex and a highly regulated profession which makes the application of rigid theories more challenging. CoPs, which have their origins in Social Learning Theory, represents a potentially more viable approach to bridging the theory-practice gap.
Conclusion
Cultivating and maintaining CoPs is a more practical approach to improve knowledge dissemination, EBP and CPD, allowing radiographers in practice to share knowledge, best practices, and experiences out with an organisational hierarchy. The collective pool of knowledge, and history created may contribute to further establishing the radiography profession and the radiographer identity as the CoPs connect, expand, and advance over time.
Implications for practice
CoPs may be cultivated and further investigated in radiography practice to improve knowledge dissemination, EBP and CPD, with the ultimate aim of improving individual and organisational performance in radiography practices.
