Five recommendations to advance implementation science for humanitarian settings: the next frontier of humanitarian research.

Challenges in delivering evidence-based programming in humanitarian crises require new strategies to enhance implementation science for better decision-making. A recent scoping review highlights the scarcity of peer-reviewed studies on implementation in conflict zones. In this commentary, we build on this scoping review and make five recommendations for advancing implementation science for humanitarian settings. These include (1) expanding existing frameworks and tailoring them to humanitarian dynamics, (2) utilizing hybrid study designs for effectiveness-implementation studies, (3) testing implementation strategies, (4) leveraging recent methodological advancements in social and data science, and (5) enhancing training and community engagement. These approaches aim to address gaps in understanding intervention effectiveness, scale, sustainability, and equity in humanitarian settings. Integrating implementation science into humanitarian research is essential for informed decision-making and improving outcomes for affected populations.
