目前的指南指出,在进入急性护理环境之前,对严重急性呼吸道冠状病毒2型(SARS-CoV-2)进行无症状筛查是由设施自行决定的。本研究的目的是估计在4种测试方法和不同假设下未被发现的SARS-CoV-2住院患者的数量。设计和设置北卡罗来纳州104家急诊医院基于个体的微观模拟患者:从2021年12月15日至2022年1月13日[即SARS-COV-2 o(omicron)变异激增期间]所有模拟的急性护理医院住院患者。干预我们模拟(1)仅检测有症状的患者,(2)1阶段抗原检测,无确证性聚合酶链反应(PCR)检测,结果1个月内,共有77,980人入院:13. 7%为COVID-19,4. 3%为COVID-19,82. 0%为非COVID-19适应症,无当前感染。在没有无症状筛查的情况下,共有1,089例(可信区间[CI],946- 1,253)SARS-CoV-2感染(7.72%)未被发现。通过1阶段抗原筛查,检测到734例(CI,638-845)无症状感染者(67.4%),假阳性1,277例。联合抗原和PCR筛查,检测到1,007例(CI,875- 1,159)无症状感染者(92.5%),假阳性5,578例。一系列的抗原检测政策检测973(CI,845- 1120)无症状感染(89.4%),与2,529假阳性conclusionsSerial抗原检测确定>85%的无症状感染,并导致更少的假阳性,以更低的成本,每个确定的感染相比,联合抗原加PCR检测。
ObjectiveCurrent guidance states that asymptomatic screening for severe acute respiratory coronavirus virus 2 (SARS-CoV-2) prior to admission to an acute-care setting is at the facility’s discretion. This study’s objective was to estimate the number of undetected cases of SARS-CoV-2 admitted as inpatients under 4 testing approaches and varying assumptions.Design and settingIndividual-based microsimulation of 104 North Carolina acute-care hospitalsPatients:All simulated inpatient admissions to acute-care hospitals from December 15, 2021, to January 13, 2022 [ie, during the SARS-COV-2 ο (omicron) variant surge].InterventionsWe simulated (1) only testing symptomatic patients, (2) 1-stage antigen testing with no confirmatory polymerase chain reaction (PCR) test, (3) 1-stage antigen testing with a confirmatory PCR for negative results, and (4) serial antigen screening (ie, repeat antigen test 2 days after a negative result).ResultsOver 1 month, there were 77,980 admissions: 13.7% for COVID-19, 4.3% with but not for COVID-19, and 82.0% for non–COVID-19 indications without current infection. Without asymptomatic screening, 1,089 (credible interval [CI], 946–1,253) total SARS-CoV-2 infections (7.72%) went undetected. With 1-stage antigen screening, 734 (CI, 638–845) asymptomatic infections (67.4%) were detected, with 1,277 false positives. With combined antigen and PCR screening, 1,007 (CI, 875–1,159) asymptomatic infections (92.5%) were detected, with 5,578 false positives. A serial antigen testing policy detected 973 (CI, 845–1,120) asymptomatic infections (89.4%), with 2,529 false positives.ConclusionsSerial antigen testing identified >85% of asymptomatic infections and resulted in fewer false positives with less cost per identified infection compared to combined antigen plus PCR testing.
