Nursing Administration Quarterly ():10.1097/NAQ.0000000000000569, January 18, 2023. | DOI: 10.1097/NAQ.0000000000000569 Buy SDC PAP Metrics Abstract Routine implementation and sustainability of evidence-based practices (EBPs) into health care is often the most difficult stage in the change process. Despite major advances in implementation science and quality improvement, a persistent 13- to 15-year research-to-practice gap remains. Nurse leaders may benefit from tools to support implementation that are based on scientific evidence and can be readily integrated into complex health care settings. This article describes development and evaluation of an evidence-based implementation and sustainability toolkit used by health care clinicians seeking to implement EBPs. For this project, implementation science and EBP experts created initial iterations of the toolkit based on Rogers' change theory, the Advancing Research through Close Collaboration (ARCC) model, and phases and strategies from implementation science. Face validity and end-user feedback were obtained after piloting the tool with health care clinicians participating in immersive EBP sessions. The toolkit was then modified, with subsequent content validity and usability evaluations conducted among implementation science experts and health care clinicians. This article presents the newly updated Fuld Institute Evidence-based Implementation and Sustainability Toolkit for health care settings. Nurse leaders seeking to implement EBPs may benefit from an evidence-based toolkit to provide a science-informed approach to implementation and sustainability of practice changes. © 2023 Wolters Kluwer Health, Inc.
