Simulated net‐benefit of polymerase chain reaction test for COVID‐19 among asymptomatic patients

Abstract

In order to prevent the in-hospital novel coronavirus disease 2019 (COVID-19) pandemic, some authorities suggested that polymerase chain reaction (PCR) testing should be performed on all patients admitted to the emergency department even if they are asymptomatic [1]. However, it is unclear whether this strategy is effective or not. Thus, our simulation study showed the circumstances and net benefits of performing PCR testing for all asymptomatic patients.
