Asymptomatic Testing of Hospital Admissions for SARS-CoV-2: Is it OK to Stop?

Abstract

Abstract Universal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing of all persons admitted to acute care hospitals has become common practice. We describe why 1 hospital discontinued this practice after weighing potential benefits against known harms. Considerations around the benefits shifted as we saw a decline in SARS-CoV-2 community transmission and coronavirus disease 2019 (COVID-19) severity of illness, increased availability of vaccines and treatments, and better understood the many other transmission pathways in the healthcare environment. Considerations around harms included the additional strain on laboratory and infection prevention resources, and several unintended adverse consequences of admission screening for patients, including unnecessary isolation, antiviral treatments, and delays in care delivery. Poor test performance for detection of infectiousness also played a significant role in determining to stop universal screening. No increase in hospital-onset COVID-19 has been documented since discontinuation of admission testing. We continue to apply other established layers of prevention while monitoring for any change in incidence of within-facility transmission of SARS-CoV-2.
