The article addresses the critical importance of implementation strategies in healthcare practice and the challenges faced in specifying and reporting these strategies. It highlights that implementation strategies, which are crucial for changing healthcare practices, are often inconsistently labeled, poorly described, lack theoretical justification, and are part of 'packaged' approaches with unclear elements. The authors propose guidelines for naming, defining, and operationalizing implementation strategies in seven dimensions: actor, action, action targets, temporality, dose, implementation outcomes addressed, and theoretical justification. These guidelines aim to improve the clarity and reproducibility of implementation strategies, enabling better measurement and comparison in research and practice. The article also discusses the need for journals to adopt reporting guidelines to advance knowledge about implementation strategies and suggests that researchers should provide detailed descriptions of their strategies to facilitate meta-analysis and replication.The article addresses the critical importance of implementation strategies in healthcare practice and the challenges faced in specifying and reporting these strategies.
