Coronavirus 2019 (COVID-19) venovenous extracorporeal oxygenation: Single community hospital results and insights.

BACKGROUND: The role of extracorporeal membrane oxygenation (ECMO) for patients with refractory respiratory failure due to coronavirus 2019 (COVID-19) is still unclear even now over a year into the pandemic. ECMO is becoming more commonplace even at smaller community hospitals. While the advantages of venovenous (VV) ECMO in acute respiratory distress syndrome (ARDS) from COVID-19 have not been fully determined, we believe the benefits outweighed the risks in our patient population. Here we describe all patients who underwent VV ECMO at our center. METHODS: All patients placed on ECMO at our center since the beginning of the pandemic, May 5, 2020, until February 20, 2021 were included in our study. All patients placed on ECMO during the time period described above were followed until discharge or death. The primary endpoint was in-hospital death. Secondary outcomes included discharge disposition, that is, whether patients were sent to a long-term acute care center (LTAC), inpatient rehabilitation, or went directly home. RESULTS: A total of 41 patients were placed on VV ECMO for refractory acute respiratory failure. Survival to discharge, the primary end point, was 63.4% (26/41). Inpatient mortality was 36.6% (15/41). CONCLUSIONS: We show here that a successful high-volume VV ECMO program for ARDS is achievable at even a medium-size community hospital. We think our success can be replicated by most small- and medium-size community hospitals with cardiothoracic surgery programs and intensivist teams.

Evaluation of the Abbott BinaxNOW COVID-19 Test Ag Card for rapid detection of SARS-CoV-2 infection by a local public health district with a rural population.

SARS-CoV-2 RT-PCR, the gold standard for diagnostic testing, may not be readily available or logistically applicable for routine COVID-19 testing in many rural communities in the United States. In this validation study, we compared the BinaxNOW™ COVID-19 Test Ag Card with SARS-CoV-2 RT-PCR in 214 participants who sought COVID-19 testing from a local public health district in Idaho, USA. The median age of participants was 35 and 82.7% were symptomatic. Thirty-seven participants (17.3%) had positive RT-PCR results. Results between the two tests were 94.4% concordant. The sensitivity of the BinaxNOW™ COVID-19 Test Ag Card was 67.6% (95% CI: 50.2-81.9%), and the specificity was 100.0% (95% CI: 97.9-100.0%). The positive predictive value (PPV) for the BinaxNOW™ COVID-19 Test Ag Card was 100.0% (95% CI: 86.2-100.0%), and the negative predictive value (NPV) was 93.6% (95% CI: 89.1-96.6%). Although the sensitivity of BinaxNOW™ COVID-19 Test Ag Card was lower than RT-PCR, rapid results and high specificity support its use for early detection of COVID-19, especially in settings where SARS-CoV-2 RT-PCR testing is not readily available. Rapid antigen tests, such as the BinaxNOW™ COVID-19 Test Ag Card, may be a more convenient tool in quickly identifying and preventing COVID-19 transmission, especially in rural settings.
