Project Summary/Abstract In this R21 proposal, we will use implementation science approaches to study delivery of equitable syphilis prevention, doxycycline post-exposure prophylaxis (doxyPEP), in a clinic-based setting. Innovative strategies for syphilis prevention are needed to address the growing national epidemic, with disproportionate burden of disease among Black and Hispanic/Latinx sexual and gender minority persons (SGM) who have sex with men. In Chicago specifically, syphilis rates have been rising steadily, syndemic with HIV transmission. Existing public health responses – contact tracing, testing, and treatment – have not stemmed these rising rates. Recent data show that doxycycline, taken after sexual activity, is very effective at prevention of syphilis for those who may be exposed. As an emerging evidence-based intervention, key implementation information is needed to ensure equitable delivery of doxyPEP to maximize impact on the syphilis epidemic. As has been recognized with other biomedical prevention tools such as HIV pre-exposure prophylaxis, early identification of barriers to delivery is imperative. The proposed study will address gaps in doxyPEP delivery using implementation frameworks in partnership with an SGM-focused health system in Chicago, Illinois, to meet the following aims: 1) Assess determinants of doxyPEP use at the patient, provider and health system levels; 2) Identify and select community- informed implementation strategies to support doxyPEP use among populations most affected by the syphilis epidemic; and 3) Develop and evaluate acceptability, feasibility, and appropriateness of a doxyPEP implementation strategy package among patients, providers, and health systems stakeholders. Our mixed methods approach will be rooted in the Consolidated Framework for Implementation Research (CFIR) and the Capability, Opportunity, and Motivation Model of Behavior (COM-B), incorporating qualitative methods and conjoint analysis approaches, to identify important determinants of doxyPEP service delivery. The proposed research will result in implementation strategies to guide equitable use of doxycycline post-exposure prophylaxis among populations most impacted by syphilis.

项目概要/摘要 在本 R21 提案中，我们将使用实施科学方法来研究公平梅毒的实施 预防，多西环素暴露后预防（doxyPEP），在临床环境中的创新策略。 需要预防梅毒来应对日益严重的全国性流行病，以及疾病负担过重的问题 与男性发生性行为的黑人和西班牙裔/拉丁裔性少数群体 (SGM)。 特别是在芝加哥，梅毒发病率一直在稳步上升，该综合症与现有的艾滋病毒传播有关。 健康应对措施——接触者追踪、检测和治疗——并没有阻止最近的数据上升。 研究表明，性活动后服用多西环素对于那些可能患有梅毒的人来说非常有效地预防梅毒。 作为一种新兴的基于证据的干预措施，需要关键的实施信息来确保。 公平地提供 doxyPEP，以最大程度地影响梅毒流行，正如其他方面所认识到的那样。 生物医学预防工具，如艾滋病毒暴露前预防、及早识别分娩障碍 拟议的研究将利用实施框架解决 doxyPEP 交付方面的差距。 与伊利诺伊州芝加哥市以 SGM 为重点的卫生系统建立伙伴关系，以实现以下目标： 1) 评估 2）识别并选择社区- 支持在受梅毒影响最严重的人群中使用 doxyPEP 的知情实施策略 流行病；以及 3) 制定并评估 doxyPEP 的可接受性、可行性和适当性 患者、提供者和卫生系统利益相关者之间的实施策略包。 方法方法将植根于实施研究综合框架（CFIR）和 能力、机会和动机行为模型 (COM-B)，结合定性方法和 联合分析方法，以确定 doxyPEP 服务提供的重要决定因素。 研究将制定指导公平使用强力霉素、暴露后实施预防的策略 受梅毒影响最严重的人群。
