چکیده :
BACKGROUND: Computed tomography (CT) pulmonary angiography use has increased dramatically, raising
concerns for patient safety. Adherence to recommendations and guidelines may protect patients. We measured
adherence to the recommendations of Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED
II) investigators for evaluation of suspected pulmonary embolism and the rate of potential false-positive
pulmonary embolism diagnoses when recommendations of PIOPED II investigators were not followed.
METHODS: We used a structured record review to identify 3500 consecutive CT pulmonary angiograms
performed to investigate suspected pulmonary embolism in 2 urban emergency departments, calculating
the revised Geneva score (RGS) to classify patients as “pulmonary embolism unlikely” (RGS10) or
“pulmonary embolism likely” (RGS10). CT pulmonary angiograms were concordant with PIOPED II
investigator recommendations if pulmonary embolism was likely or pulmonary embolism was unlikely and
a highly sensitive D-dimer test result was positive. We independently reviewed 482 CT pulmonary
angiograms to measure the rate of potential false-positive pulmonary embolism diagnoses.
RESULTS: A total of 1592 of 3500 CT pulmonary angiograms (45.5%) followed the recommendations of
PIOPED II investigators. The remaining 1908 CT pulmonary angiograms were performed on patients with
an RGS10 without a D-dimer test (n1588) or after a negative D-dimer test result (n320). The
overall rate of pulmonary embolism was 9.7%. Potential false-positive diagnoses of pulmonary embolism
occurred in 2 of 3 patients with an RGS10 and a negative D-dimer test result.
CONCLUSIONS: Nonadherence to recommendations for CT pulmonary angiography is common and
exposes patients to increased risks, including potential false-positive diagnoses of pulmonary embolism.
