接触者追踪是传染病控制和预防的重要步骤。使用电子病历（EMR）具有挑战性，并错过了许多潜在的风险。真实的时间定位系统（RTLS）使百日咳疾病的潜在暴露名单比传统的基于EMR的接触者识别方法增加了一倍。RTLS在接触者追踪过程中更有效和及时。需要更大样本量的进一步研究来证实这一发现。接触者追踪是识别可能接触传染病的个人的系统方法。电子病历（EMR）用于接触者追踪是耗时的，可能会错过暴露的个人。实时定位系统（RTLS）可以改进接触识别。因此，评价了这2种接触者追踪方法的相对有效性。在美国百日咳爆发期间，2016年6月14日至8月31日进行了一项回顾性病例研究，以确定确诊百日咳病例的接触者，使用三级医疗中心急诊科的EMR和RTLS数据。进行描述性统计和配对t检验（α = 0.05），以比较EMR与RTLS识别的接触者，以及百日咳患者住院时间与潜在接触者数量之间的相关性。在确定的时间段内，9例百日咳病例被送到急诊室。RTLS使潜在暴露列表加倍（P < .01）。住院时间与RTLS识别的接触者有显著正相关性（ρ = 0.79; P = 0.01），但与EMR无相关性（ρ = 0.43; P = 0.25）。RTLS使潜在的百日咳暴露增加了一倍，超出了基于EMR的接触识别。因此，RTLS可能是接触者追踪和传染病监测实践的一个有价值的补充。
Contact tracing is an essential step in infectious disease control and prevention. Using Electronic medical record (EMR) is challenging and misses a number of potential exposures. Real time location system (RTLS) doubled the potential exposures list for pertussis disease beyond the conventional method of EMR-based contact identification RTLS is more efficient and timely in the process of contact tracing. Further studies with larger sample size are needed to confirm the findings. Contact tracing is the systematic method of identifying individuals potentially exposed to infectious diseases. Electronic medical record (EMR) use for contact tracing is time-consuming and may miss exposed individuals. Real-time location systems (RTLSs) may improve contact identification. Therefore, the relative effectiveness of these 2 contact tracing methodologies were evaluated. During a pertussis outbreak in the United States, a retrospective case study was conducted between June 14 and August 31, 2016, to identify the contacts of confirmed pertussis cases, using EMR and RTLS data in the emergency department of a tertiary care medical center. Descriptive statistics and a paired t test (α = 0.05) were performed to compare contacts identified by EMR versus RTLS, as was correlation between pertussis patient length of stay and the number of potential contacts. Nine cases of pertussis presented to the emergency department during the identified time period. RTLS doubled the potential exposure list (P < .01). Length of stay had significant positive correlation with contacts identified by RTLS (ρ = 0.79; P = .01) but not with EMR (ρ = 0.43; P = .25). RTLS doubled the potential pertussis exposures beyond EMR-based contact identification. Thus, RTLS may be a valuable addition to the practice of contact tracing and infectious disease monitoring.
