While many interventions have reduced transmission of HIV or increased access to HIV care, fewer have been scaled-up or sustained. Implementation science (IS) maximizes the population-level impact of interventions, but globally, knowledge about IS among researchers and policymakers is limited, particularly in low and middle-income countries. This gap can be addressed through an innovative IS training model, the Depth and Diffusion Model, that can be used to build implementation science capacity to increase equity in the distribution of global implementation science training programs.
In the Depth and Diffusion Model, creates an in-country institution as a leader in IS research and training; diffusion ensures the spread of fundamental IS knowledge across universities and governmental agencies throughout the country. We are using the Depth and Diffusion Model in the Vietnam Implementation Science Advancement Program (VISA), a case study of applying this model in practice. VISA's goals are to: 1) initiate the Hanoi Medical University Implementation Science Program; 2) develop IS knowledge and research capacity among four universities in Vietnam; and 3) cultivate IS capacity among Vietnamese policymakers and health program leaders.
The Depth and Diffusion Model is being used to efficiently scale-up IS knowledge among researchers and policymakers, while fostering collaboration to increase impact of research and policies. By the end of VISA, HIV-related IS capacity will be well-established in Vietnam, demonstrating how the Depth and Diffusion Model can be a blueprint for adoption of IS research and practice in a country with limited previous IS capacity.
虽然许多干预措施减少了艾滋病毒的传播或增加了获得艾滋病毒治疗的机会，但扩大规模或持续实施的措施较少。实施科学（IS）可使干预措施在人群层面产生最大影响，但在全球范围内，研究人员和政策制定者对实施科学的了解有限，尤其是在低收入和中等收入国家。这种差距可以通过一种创新的实施科学培训模式——深度与扩散模式来解决，该模式可用于建设实施科学能力，以提高全球实施科学培训项目分配的公平性。
在深度与扩散模式中，创建一个国内机构作为实施科学研究和培训的领导者；扩散确保基本的实施科学知识在全国的大学和政府机构中传播。我们正在越南实施科学推进项目（VISA）中使用深度与扩散模式，这是一个在实践中应用该模式的案例研究。VISA的目标是：1）启动河内医科大学实施科学项目；2）在越南的四所大学中培养实施科学知识和研究能力；3）在越南政策制定者和卫生项目领导者中培养实施科学能力。
深度与扩散模式正被用于在研究人员和政策制定者中有效扩大实施科学知识，同时促进合作以增强研究和政策的影响。到VISA结束时，越南将建立完善的与艾滋病毒相关的实施科学能力，这表明深度与扩散模式如何能够成为在先前实施科学能力有限的国家采用实施科学研究和实践的蓝图。
