DECREASING UTILIZATION OF CT PULMONARY ANGIOGRAMS IN COVID-19-POSITIVE PATIENTS USING D-DIMER LEVELS

ABSTRACT

Patients admitted (Jan-May 2021) to 2 community hospitals with COVID-19 who underwent CTPA to rule out PE and had D-dimer within 48 hours prior to scan were included. We aimed to identify and validate a D-dimer value that is sensitive for assessing pre-test probability in COVID-19 patients. D-Dimer values are used in patients without COVID-19 to help assess pre-test probability of PE.
