“…As defined by Proctor et al, 43 implementation outcomes are “the effects of deliberate and purposive actions to implement new treatments, practices, and services.” In addition to the aforementioned RE-AIM model, other implementation outcomes include acceptability, adoption, appropriateness, costs, feasibility, fidelity, penetration (or reach), and sustainability. 44,45 Options for measuring these outcomes include, for instance, (a) conducting focus groups with practitioners to determine the extent to which an intervention can be sustainably used in practice, (b) completing chart reviews to evaluate practitioners’ adoption of a particular intervention or standardized assessment, and (c) observing the behavioral patterns of practitioners to assess their level of fidelity to an intervention protocol. Proctor et al 43 provide in-depth descriptions of each of these implementation outcomes as well as recommendations for measurement.…”
