OBJECTIVE
To describe utilization of at-home coronavirus disease 2019 (COVID-19) testing among healthcare workers (HCW).
DESIGN
Serial cross-sectional study.
SETTING AND PARTICIPANTS
HCWs in the Chicago area.
METHODS
Serial surveys were conducted from the Northwestern Medicine (NM HCW SARS-CoV-2) Serology Cohort Study. In April 2022, participants reflected on the past 30 days to complete an online survey regarding COVID-19 home testing. Surveys were repeated in June and November 2022. The percentage of completed home tests and ever-positive tests were reported. Multivariable Poisson regression was used to calculate prevalence rate ratios (PRR) and univariate analysis was used for association between participant characteristics with home testing and positivity.
RESULTS
Overall, 2,226 (62.4%) of 3,569 responded to the survey in April. Home testing was reported by 26.6% of respondents and 5.9% reported having at least one positive home test. Testing was highest among those 30-39 years old (35.9%) and nurses (28.3%). A positive test was associated ( < .001) with exposure to people, other than patients with known or suspected COVID-19. Home testing increased in June to 36.4% (positivity 19.9%) and decreased to 25% (positivity 13.5%) by November.
CONCLUSION
Our cohort findings show the overall increase in both home testing and ever positivity from April to November - a period where changes in variants of concern of SARS-CoV-2 were reported nationwide. Having an exposure to people, other than patients with known or suspected COVID-19 was significantly associated with both, higher home testing frequency and ever-test positivity.
目的
描述医护人员对2019冠状病毒病（COVID-19）居家检测的使用情况。
设计
系列横断面研究。
地点和参与者
芝加哥地区的医护人员。
方法
来自西北医学（NM医护人员SARS-CoV-2）血清学队列研究的系列调查。2022年4月，参与者回顾过去30天，完成一项关于COVID-19居家检测的在线调查。2022年6月和11月重复进行调查。报告了完成居家检测的百分比和曾检测呈阳性的情况。使用多变量泊松回归计算患病率比（PRR），并使用单变量分析来研究参与者特征与居家检测及检测阳性之间的关联。
结果
总体而言，3569名参与者中有2226名（62.4%）在4月回复了调查。26.6%的受访者报告进行了居家检测，5.9%的受访者报告至少有一次居家检测呈阳性。检测率在30 - 39岁人群中最高（35.9%），护士中检测率为（28.3%）。检测呈阳性与接触已知或疑似COVID-19患者以外的其他人有关（P <.001）。6月居家检测率增至36.4%（阳性率19.9%）。到11月降至25%（阳性率13.5%）。
结论
我们队列研究的结果显示，从4月到11月，居家检测和曾检测呈阳性的情况总体上有所增加——这一时期全国报告了严重急性呼吸综合征冠状病毒2（SARS-CoV-2）关注变异株的变化。接触已知或疑似COVID-19患者以外的其他人与更高的居家检测频率和曾检测阳性均显著相关。
