The objective of this paper was to describe the process of transferring two methods for sampling most-at-risk populations: respondent-driven sampling (RDS) and time-space sampling (TSS). The article describes steps in the process, the methods used in the 10 pilot studies, and lessons learned. The process was conducted in six steps, from a state-of-the-art seminar to a workshop on writing articles with the results of the pilot studies. The principal investigators reported difficulties in the fieldwork and data analysis, independently of the pilot sampling method. One of the most important results of the transfer process is that Brazil now has more than 100 researchers able to sample MARPs using RDS or TSS. The process also enabled the construction of baselines for MARPS, thus providing a broader understanding of the dynamics of HIV infection in the country and the use of evidence to plan the national response to the epidemic in these groups.
本文旨在描述两种最易感人群抽样方法（RDS 和 TSS）的转移过程。本文描述了这一过程的步骤、10 项试点研究中使用的方法以及得出的经验教训。该过程分六个步骤进行，从最先进的研讨会到关于试点研究结果的文章撰写研讨会。主要调查人员报告说，现场工作和数据分析存在困难，这与试点抽样方法无关。转移过程的最重要结果之一是，巴西现在有 100 多名研究人员能够使用 RDS 或 TSS 对 MARPs 进行抽样。该过程还为 MARPs 建立了基线，从而更全面地了解该国 HIV 感染的动态，并利用证据来规划针对这些群体的国家应对措施。
