Key result
The likelihood of an emergency department diagnosis of pulmonary embolism increased significantly per year from 2001 to 2010 (OR 1.091), but this trend was no longer significant when adjusted for the use of computed tomography.

CT use likely explains rising ED PE diagnoses; leaves open whether incidence changed or overdiagnosis increased.

The proportion of ED visits with a diagnosis of pulmonary embolism increased significantly from 2001 to 2010, a rise largely attributable to the increased availability and use of computed tomography.
Schissler et al. (2015) conducted a cross-sectional in Pulmonary embolism (n=357,681). Calendar year (2001-2010) was evaluated on Likelihood of having a diagnosis of pulmonary embolism per year (OR 1.091, 95% CI 1.034-1.152, p=0.002). The likelihood of an emergency department diagnosis of pulmonary embolism increased significantly per year from 2001 to 2010 (OR 1.091), but this trend was no longer significant when adjusted for the use of computed tomography.
