Over the past decade, CDC has been implementing a high-impact prevention (HIP) approach to HIV, directing funds towards activities with the greatest likelihood of reducing new infections and disparities. Corresponding to this shift, the Division of HIV/AIDS Prevention (DHAP) began funding a series of multi-site demonstration projects to provide extra support and evaluative capacity to select health departments to initiate new HIP programming, with the intention of ascertaining and sharing lessons with other health departments. In this paper, we provide context for the PrEP, Implementation, Data2Care, Evaluation (PrIDE) evaluation by describing the evolution of evaluation goals and activities across three prior demonstration projects, highlighting four areas of change: 1) integrated evaluation and program implementation; 2) local program evaluation in addition to cross-site performance monitoring; 3) prescriptive allocation of resources to support local program evaluation; and 4) expansion beyond single site program evaluation to identify effective cross-site programmatic strategies. Together, these changes reflect our own learning about achieving the greatest contribution from multi-site projects and set the stage for unique aspects of program evaluation within PrIDE. We describe these features, concluding with lessons learned from this most recent approach to structuring and supporting evaluation within CDC DHAP’s health department demonstration projects.

在过去的十年中，CDC 一直在对 HIV 实施高影响力预防 (HIP) 方法，将资金用于最有可能减少新感染和差异的活动。与这种转变相对应，艾滋病毒/艾滋病预防司 (DHAP) 开始资助一系列多地点示范项目，为选择卫生部门启动新的 HIP 计划提供额外的支持和评估能力，目的是确定和分享经验教训与其他卫生部门。在本文中，我们提供了PrEP、实施、Data2Care、评估的背景(PrIDE) 评估，通过描述评估目标和活动在三个先前示范项目中的演变，突出四个变化领域：1) 综合评估和计划实施；2) 除跨站点性能监控外，还进行本地程序评估；3) 资源的规范性分配以支持地方项目评估；4) 扩展到单一站点项目评估之外，以确定有效的跨站点项目策略。总之，这些变化反映了我们自己对从多站点项目中获得最大贡献的学习，并为 PrIDE 中项目评估的独特方面奠定了基础。我们描述了这些特征，
