BACKGROUND: Public health emergencies – such as the 2020 COVID19 pandemic –accelerate the need for both evidence generation and rapid dissemination and implementation (D&I) of evidence where it is most needed. In this paper, we reflect on how D&I frameworks and methods can be pragmatic (i.e., relevant to real-world context) tools for rapid and iterative planning, implementation, evaluation, and dissemination of evidence to address public health emergencies. The Pragmatic, Rapid, and Iterative D&I (PRIDI) Cycle: The PRIDI Cycle is based on a “double-loop” learning process, reflecting the iterative and adaptive D&I, along with iterative re-consideration of goals and priorities, interventions and corresponding D&I strategies, and needs and capacities of individuals and contexts. Stakeholder engagement is essential- which itself is an evolving activity. The results of iterative evaluations should be communicated with local implementers and stakeholders through customized feedbacks. CONCLUSION: Even when the health system priority is provision of the best care to the individuals in need, and scientists are focused on development of effective diagnostic and therapeutic technologies, planning for D&I is critical. Without a flexible and adapting process of D&I, which is responsive to emerging evidence generation cycles, and is closely connected to stakeholders and target users through engagement and feedback, the interventions to mitigate public health emergencies – such as the COVID19 pandemic - will have limited reach and impact on populations that would most benefit. The PRIDI cycle is intended to provide a pragmatic approach to support planning for D&I throughout the evidence generation process.
