Implementation Science and Evaluation
Summary
Implementation science investigates the methods and strategies that promote the systematic uptake of evidence-based interventions within real-world settings. It focuses on understanding how contextual factors—organisational structures, cultural norms, policy environments and stakeholder perspectives—influence the adoption, fidelity, adaptation and sustainability of programmes. Evaluation in this domain encompasses both implementation outcomes (acceptability, feasibility, fidelity, reach, adoption and sustainability) and service or client outcomes (effectiveness, equity, cost and patient satisfaction). Widely used frameworks—such as the Consolidated Framework for Implementation Research (CFIR), RE-AIM and Proctor’s taxonomy of implementation outcomes—guide the design, assessment and continuous refinement of interventions. Mixed-methods approaches, combining quantitative process indicators with qualitative insights, are central to capturing dynamic implementation processes and informing iterative improvements. By bridging the ‘know–do’ gap, this field ensures that proven interventions are delivered with high quality and sustained impact across diverse health and social care contexts worldwide.

Implementation Science and Evaluation publication trend
The graph below shows the total number of articles in implementation science and evaluation across all publications each year (not limited to Nature Index journals).
Technical terms
Implementation strategy: A deliberate method or technique employed to facilitate the uptake, adoption and sustainability of an intervention in practice.
Implementation outcome: A quantifiable effect of strategies aimed at implementing an intervention, including acceptability, feasibility, fidelity, adoption, reach and sustainability.
Fidelity: The extent to which an intervention is delivered as originally designed and prescribed.
Tailoring variable: A contextual or individual attribute—such as stress level, activity pattern or environmental cue—used to adapt intervention content or delivery.
Process evaluation: An assessment of implementation processes that uncovers barriers, facilitators and contextual influences to inform ongoing optimisation and scale-up.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
