Developing a conceptual framework for implementation science to evaluate a nutrition intervention scaled-up in a...

Area of Science:

• Implementation Science
• Public Health Interventions
• Nutrition Programs

Background:

• Assessing nutrition interventions in real-world settings requires robust frameworks.
• Existing implementation science frameworks may not fully address the complexities of nutrition programs.

Purpose of the Study:

• To identify and develop a comprehensive conceptual framework using implementation science.
• To apply this framework to assess a nutrition intervention in a real-world setting.

Main Methods:

• Conducted a narrative review of implementation science frameworks, models, and theories.
• Performed a qualitative thematic analysis to generate a novel framework.
• Applied the developed framework to a nutrition implementation program in Bangladesh.

Main Results:

• Developed a comprehensive implementation science framework with three domains: efficacy to effectiveness trials, scaling-up, and sustainability.
• The framework includes five key components for identifying effective interventions, scaling-up, fidelity, course correction, and sustainability.
• Successfully applied the framework to a nutrition program, demonstrating its practical utility.

Conclusions:

• The developed framework offers a holistic approach for implementation researchers, policymakers, and program managers.
• Provides guidance for identifying, scaling-up, and sustaining effective nutrition interventions.
• Enhances the successful translation of evidence-based nutrition interventions into practice.
