Evidence-based healthcare, knowledge translation, implementation science and radiography: What does it all mean?

Evidence-based healthcare is an approach to practice whereby decision making and service delivery considers the best available evidence, patient choice, local resources and clinical expertise. Although sound in theory, compliance with evidence-based practice is often far from optimal. To address this, related fields such as knowledge translation and implementation science have emerged, which largely focus on methods and techniques to facilitate the transfer of evidence into practice. This introductory article explains the key concepts of evidence-based healthcare by using the JBI Model as a framework to highlight the lifecycle of evidence-based information. Throughout the article we refer to exemplars from medical radiation to highlight these concepts.
