We assessed the timeliness of contact tracing following rapid-positive COVID-19 test result at point-of-care testing (POCT) sites in New York City (NYC).
Interviewed case-patients to elicit exposed contacts and conducted COVID-19 exposure notifications.
Twenty-two COVID-19 POCT sites in NYC, the 2 NYC international airports, and 1 ferry terminal.
Case-patients with rapid-positive COVID-19 test results and their named contacts.
We quantified the proportions of interviewed individuals with COVID-19 and notified contacts and assessed the timeliness between the dates of the rapid-positive COVID-19 test results and the interviews or notifications.
In total, 11 683 individuals with rapid-positive COVID-19 test results were referred for contact tracing on the day of their diagnosis; 8878 (76) of whom were interviewed within 1 day of diagnosis, of whom 5499 (62%) named 11 486 contacts. A median of 1.24 contacts were identified from each interview. The odds of eliciting contacts were significantly higher among individuals reporting COVID-19 symptoms than among persons with no symptoms (51% vs 36%; adjusted odds ratio [aOR] = 1.37; 95% confidence interval [CI], 1.11-1.70) or living with 1 or more persons than living alone (89% vs 38%; aOR = 12.11; 95% CI, 10.73-13.68). Among the 8878 interviewed case-patients, 8317 (94%) were interviewed within 1 day of their rapid-positive COVID-19 test results and 91% of contact notifications were completed within 1 day of contact identification. The median interval from test result to interview date and from case investigation interview to contact notification were both 0 days (IQR = 0).
The integration of contact tracers into COVID-19 POCT workflow achieved timely case investigation and contact notification. Accelerated contact tracing can be used to curb COVID-19 transmission during local outbreaks.
我们评估了在纽约市（NYC）的即时检测（POCT）点快速阳性 COVID-19 检测结果后接触者追踪的及时性。
采访病例患者以确定暴露接触者，并进行 COVID-19 接触通知。
NYC 的 22 个 COVID-19 POCT 点、NYC 的 2 个国际机场和 1 个渡轮码头。
快速阳性 COVID-19 检测结果的病例患者及其指定联系人。
我们量化了接受采访的 COVID-19 患者和通知接触者的比例，并评估了快速阳性 COVID-19 检测结果日期与访谈或通知日期之间的及时性。
总共 11683 名快速阳性 COVID-19 检测结果的患者在诊断当天被转介进行接触者追踪；其中 8878 名（76%）在诊断后 1 天内接受了采访，其中 5499 名（62%）确定了 11486 名接触者。从每次采访中确定了中位数为 1.24 个接触者。与无症状者（51%比 36%；调整后的优势比[aOR] = 1.37；95%置信区间[CI]，1.11-1.70）或与 1 人或多人同住者相比，报告 COVID-19 症状的个体报告接触者的可能性明显更高（89%比 38%；aOR = 12.11；95%CI，10.73-13.68）。在接受采访的 8878 名病例患者中，8317 名（94%）在快速阳性 COVID-19 检测结果后 1 天内接受了采访，91%的接触通知在确定接触者后 1 天内完成。从检测结果到访谈日期以及从病例调查访谈到接触通知的中位数间隔均为 0 天（IQR = 0）。
接触追踪者整合到 COVID-19 POCT 工作流程中实现了及时的病例调查和接触通知。加速接触者追踪可用于遏制当地疫情期间 COVID-19 的传播。
