Implementation research examines and promotes the uptake of research findings in various operational environments. The concepts of implementation research in Finnish are not yet established. In support of the research field we describe the Finnish equivalents of the central terms related to knowledge translation in healthcare and the frame of reference of Implementation research, with the national Current Care Guidelines as the starting point. The frame of reference is based on literature, experiences of the authors, iterative modification of the frame of reference on the basis of discussions, and results of expert inquiry. The frame of reference describes seven objects of evaluation, examples of research set-ups and methods as well as tools.
