ABSTRACT Policy makers and healthcare providers increasingly seek broad, multi-sectoral responses to manage, mitigate, and eventually eliminate the HIV epidemic. Such community health outcomes depend on a coordinated and highly effective local HIV test-and-treat (T&T) service system to find, treat and maintain viral suppression in all people with HIV (PWH). System improvements require stakeholder coalitions from across the care continuum with capacity to identify service gaps and develop and carry out strategic plans to improve service integration and delivery. However, such plans may suffer from stakeholders' incomplete `mental models' of system complexity and system dynamics (SD) that affect population health outcomes. A SD simulation model that has been developed and validated through participatory model building offers conceptual, methodological and analytical tools to achieve these goals. SD simulation modeling allows community coalitions to learn about system complexity and identify mechanisms likely to affect system improvements. They can hypothesize single, multiple, or sequenced interventions and other actions expected to achieve desired community-level and public health outcomes, then test those virtually through model simulation before expending effort and resources to implement them. However better understanding is needed of the process by which stakeholder coalitions can use SD simulation models, whether simulation can help them design strategic plans they have confidence will improve community-level health outcomes, and how this process enhances coalition capacities to move their plans forward. Our 3-year study (R01-MH103176) used mixed methods and participatory SD modeling to build a SD model of the HIV T&T care continuum in Hartford, CT. With additional funding (R21- MH110335) we triangulated expert knowledge, local primary and secondary data, and scientific evidence to calibrate the SD model for simulation. User interface tools of the SD simulation model allow recalibration/ tailoring and enable SD-modeling-naïve coalitions to use simulation for strategic planning. This 2-year renewal of our current R01 will address the following new specific aims that are outside the scope of the current studies. Using mixed qualitative and quantitative research methods, document and measure: Aim 1: the strategic planning process of a new stakeholder coalition when using a validated SD simulation model of the HIV T&T system to develop strategies expected to reduce community-level HIV; Aim 2: comparative strategic plans designed and selected by the coalition before and after training in, and throughout iterative use of, the SD simulation model of the HIV T&T system; and Aim 3: changes in coalition capacities, including member, relational, and organizational capacities, expected to improve their ability to implement proposed plans to achieve long-term system improvements. Findings from this renewal study will be used to produce a Toolkit that will make possible replication of the SD simulation modeling approach by coalitions in other communities to facilitate rigorous multisite testing in a subsequent implementation study.

抽象的 政策制定者和医疗保健提供者越来越多地寻求广泛的、多部门的应对措施来管理、缓解、 并最终消除艾滋病毒流行，这种社区健康成果取决于协调和协调。 高效的当地艾滋病毒检测和治疗 (T&T) 服务系统，可在所有人群中发现、治疗和维持病毒抑制 艾滋病毒感染者 (PWH) 系统的改进需要来自整个护理连续体的利益相关者联盟。 有能力识别服务差距并制定和实施战略计划以改善服务一体化 然而，此类计划可能会受到利益相关者不完整的系统“心智模型”的影响。 影响人口健康结果的复杂性和系统动力学 (SD) 模拟模型。 已通过参与式模型构建进行了开发和验证，提供了概念、方法和 SD 模拟建模允许社区联盟了解实现这些目标的分析工具。 系统复杂性并确定可能影响系统改进的机制。 预期达到预期社区水平的单一、多重或顺序干预措施和其他行动 和公共卫生结果，然后在投入精力之前通过模型模拟进行虚拟测试 然而，需要更好地了解利益相关者的实施过程。 联盟可以使用SD模拟模型，模拟是否可以帮助他们设计他们的战略计划 信心将改善社区一级的健康成果，以及这一过程如何增强联盟能力 我们的 3 年研究 (R01-MH103176) 使用了混合方法和参与性 SD。 在额外资金的支持下，在康涅狄格州哈特福德建立了 HIV T&T 护理连续体的 SD 模型（R21-）。 MH110335）我们对专家知识、当地一手和二手数据以及科学证据进行了三角测量， 校准 SD 模型以进行仿真 SD 仿真模型的用户界面工具允许重新校准/ 定制并支持 SD 建模新手联盟使用模拟进行战略规划。这个为期 2 年的更新。 我们当前的 R01 将解决以下新的具体目标，这些目标超出了当前的范围 使用混合定性和定量研究方法、记录和测量： 目标 1： 使用经过验证的 SD 模拟模型时，新利益相关者联盟的战略规划流程 HIV T&T 系统制定旨在减少社区一级艾滋病毒的战略 目标 2：比较战略； 联盟在训练前后以及迭代使用过程中设计和选择的计划 HIV T&T 系统的 SD 模拟模型；目标 3：联盟能力的变化，包括成员、 关系和组织能力，预计将提高他们实施拟议计划的能力 实现长期系统改进。这项更新研究的结果将用于制作工具包。 这将使其他社区的联盟复制 SD 模拟建模方法成为可能 以便在后续实施研究中进行严格的多站点测试。
