工作场所是传染病传播的一个重要但研究不足的环境。我们研究了两种不同的传感器（Opos和蓝牙信标）在办公室工作场所收集人与人接触和手部卫生的可行性。Opo是一种交互传感器，通过超声波频率捕获传感器到传感器的交互，这对应于研究参与者之间的面对面接触。Opos还被用于通过将传感器固定在肥皂和酒精洗手液分配器上来测量手部卫生事件。蓝牙信标与智能手机应用程序结合使用，并记录研究参与者之间的近距离接触。2018年3月，两个办公地点的参与者在他们的工作场所被跟踪了一周。接触模式因一天中的时间和一周中的日期而异。面对面接触的平均持续时间比近距离接触短。主管有更少的近距离接触，但更多的面对面的接触比非主管。自我报告的手部卫生显著高于传感器收集的手部卫生事件，洗手事件的持续时间较短（中位数：9秒，范围：2.5-33秒）。鉴于办公室环境是工作年龄人群花费大部分时间和互动的关键环境，需要更好地描述经验社交网络和工作场所互动的手部卫生行为，以减轻疫情爆发并为流行病做好准备。我们的研究表明，实施传感器技术来跟踪办公室中的互动和行为是可行的，可以为现实世界的社交网络和卫生习惯提供新的见解。我们确定了关键的社会互动，手部卫生的变化，以及工作场所角色的互动差异。高分辨率网络数据对于确定最有效的方法以减少传染病传播和制定工作场所环境的大流行病防备计划至关重要。
Office-based workplaces are an important but understudied context for infectious disease transmission. We examined the feasibility of two different sensors (Opos and Bluetooth beacons) for collecting person-to-person contacts and hand hygiene in office-based workplaces. Opo is an interaction sensor that captures sensor-to-sensor interactions through ultrasonic frequencies, which correspond to face-to-face contacts between study participants. Opos were additionally used to measure hand hygiene events by affixing sensors to soap and alcohol-based hand sanitizer dispensers. Bluetooth beacons were used in conjunction with a smartphone application and recorded proximity contacts between study participants. Participants in two office sites were followed for one-week in their workplace in March 2018. Contact patterns varied by time of day and day of the week. Face-to-face contacts were of shorter mean duration than proximity contacts. Supervisors had fewer proximity contacts but more face-to-face contacts than non-supervisors. Self-reported hand hygiene was substantively higher than sensor-collected hand hygiene events and duration of hand washing events was short (median: 9 seconds, range: 2.5–33 seconds). Given that office settings are key environments in which working age populations spend a large proportion of their time and interactions, a better characterization of empirical social networks and hand hygiene behaviors for workplace interactions are needed to mitigate outbreaks and prepare for pandemics. Our study demonstrates that implementing sensor technologies for tracking interactions and behaviors in offices is feasible and can provide new insights into real-world social networks and hygiene practices. We identified key social interactions, variability in hand hygiene, and differences in interactions by workplace roles. High-resolution network data will be essential for identifying the most effective ways to mitigate infectious disease transmission and develop pandemic preparedness plans for the workplace setting.
