The utility of chest computed tomography (CT) and RT-PCR screening of asymptomatic patients for SARS-CoV-2 prior to semiurgent or urgent hospital procedures
In total, 625 patients were screened for SARS-CoV-2 using a combination of phone questionnaires, RT-PCR and chest computed tomography. Of the 625 patients, 520 scans (83.2%) were interpreted as normal. 18 scans (2.88%) had indeterminate features of COVID-19; and 86 (13.76%) had atypical features of the SARS virus. After surgery, none of the patients developed signs or symptoms suspicious of SARS that would indicate the need for surgery.
