PE is suspected.
Decision
Is the patient pregnant?
Background
The YEARS algorithm was developed to reduce the use of CT Pulmonary Angiography (CTPA) in adults. It was found to reduce CTPA use by 14% compared to standard evaluation, and by 8.7% compared to age adjusted d-dimer testing.
The cut-off for D-dimer testing in the YEARS algorithm depends on your response to the questions in this pathway. The pathways begins with suspicion of PE. If you do not have a suspicion for PE, do not proceed.
