减少时间负担和提高接触者追踪效率的可扩展策略在感染传播的早期波和高峰期间至关重要。我们将一组SARS-CoV-2阳性种子病例纳入一项同行招募研究，该研究测试了社交网络方法和一种新型电子平台，以提高接触者追踪效率。索引病例从学术医学中心招募，并要求招募他们的当地社会联系人进行招募和SARS-CoV-2检测。在19个月内，共有509名成年参与者入组（384名种子病例和125名社会同龄人）。参与者完成了一项调查，然后有资格招募他们的社会联系与独特的“优惠券”登记。同伴参与者有资格进行SARS-CoV-2和呼吸道病原体筛查。主要的结果指标是通过研究确定新的SARS-CoV-2病例的测试百分比，部署平台和同伴招募策略的可行性，平台和同伴招募策略的可接受性，以及在流行高峰期间两者的可扩展性。在开发和部署之后，几乎不需要人力资源来维护平台和招募参与者，无论高峰如何。平台的可接受性很高。与该地区其他检测项目一起跟踪的阳性百分比。电子平台可能是一种适当的工具，通过允许参与者选择接触者追踪的在线平台，而不是坐下来接受采访，来加强公共卫生接触者追踪活动。
Scalable strategies to reduce the time burden and increase contact tracing efficiency are crucial during early waves and peaks of infectious transmission. We enrolled a cohort of SARS-CoV-2-positive seed cases into a peer recruitment study testing social network methodology and a novel electronic platform to increase contact tracing efficiency. Index cases were recruited from an academic medical center and requested to recruit their local social contacts for enrollment and SARS-CoV-2 testing. A total of 509 adult participants enrolled over 19 months (384 seed cases and 125 social peers). Participants completed a survey and were then eligible to recruit their social contacts with unique “coupons” for enrollment. Peer participants were eligible for SARS-CoV-2 and respiratory pathogen screening. The main outcome measures were the percentage of tests administered through the study that identified new SARS-CoV-2 cases, the feasibility of deploying the platform and the peer recruitment strategy, the perceived acceptability of the platform and the peer recruitment strategy, and the scalability of both during pandemic peaks. After development and deployment, few human resources were needed to maintain the platform and enroll participants, regardless of peaks. Platform acceptability was high. Percent positivity tracked with other testing programs in the area. An electronic platform may be a suitable tool to augment public health contact tracing activities by allowing participants to select an online platform for contact tracing rather than sitting for an interview.
