概要	Innovation Adoption refers to the extent to which an innovation, evidence-based practice, or new technology is actually used by the target population or in the target setting. Adoption is typically measured as the percentage of eligible users/staff who have adopted the innovation by a specific time point, or the trajectory of adoption over time (adoption curve). Grounded in Rogers' Diffusion of Innovations theory, adoption is a key implementation outcome distinct from readiness (willingness to adopt), fidelity (quality of delivery), or effectiveness (impact on outcomes). An innovation can be widely adopted but delivered with low fidelity, or adopted by only a subset of users despite being efficacious. Adoption curves reflect organizational readiness, innovation-context fit, and implementation strategy effectiveness. Adoption is often the first implementation outcome to emerge, typically preceding fidelity and effectiveness improvements.	The Knowledge-to-Action (KTA) Framework is a conceptual model and process guide for translating evidence into practice, developed by Ian Graham and colleagues at the Ottawa Hospital Research Institute (2004–2006). The KTA framework addresses a central challenge in implementation science: research evidence alone does not change practice; a deliberate, systematic process is required to adapt evidence to local contexts, identify and overcome implementation barriers, and sustain change. The KTA distinguishes between knowledge production (research, evidence synthesis) and knowledge application (implementation planning, barrier identification, strategy selection, execution, monitoring, and adaptation). The framework has become one of the most widely adopted implementation models in healthcare, particularly in Canada and internationally, and provides a structured approach to evidence-based practice implementation that is context-sensitive and iterative.
