The paper aims to develop a comprehensive conceptual framework using implementation science for assessing nutrition interventions in real-world settings. The qualitative thematic analysis generated a framework that includes domains such as efficacy to effectiveness trials, scaling-up, and sustainability, successfully applied in a nutrition implementation program in Bangladesh. This framework offers guidance for researchers, policymakers, and managers to identify, scale-up, and sustain effective interventions.
Objective: The aim of this paper is to identify and develop a comprehensive conceptual framework using implementation science that can be applied to assess a nutrition intervention in a real-world setting. Design: We conducted a narrative review using electronic databases and a manual search to identify implementation science frameworks, models and theories published in peer-reviewed journals. We performed a qualitative thematic analysis of these publications to generate a framework that could be applied to nutrition implementation science. Results: Based on this review, we developed a comprehensive framework which we have conceptualised as an implementation science process that describes the transition from the use of scientific evidence through to scaling-up with the aim of making an intervention sustainable. The framework consisted of three domains: Domain i - efficacy to effectiveness trials, Domain ii - scaling-up and Domain iii - sustainability. These three domains encompass five components: identifying an 'effective' intervention; scaling-up and implementation fidelity; course corrections during implementation; promoting sustainability of interventions and consideration of a comprehensive methodological paradigm to identify 'effective' interventions and to assess the process and outcome indicators of implementation. The framework was successfully applied to a nutrition implementation program in Bangladesh. Conclusions: Our conceptual framework built from an implantation science perspective offers a comprehensive approach supported by a foundational and holistic understanding of its key components. This framework provides guidance for implementation researchers, policy-makers and programme managers to identify and review an effective intervention, to scale it up and to sustain it over time.
