Acronym: MODS STRATEGY
Brief Summary: Pulmonary embolism (PE) is frequently suspected in emergency departments (ED) patients which often leads to the prescription of DDimer testing and irradiative chest imaging (Computed Tomographic Pulmonary Angiogram CTPA in most cases).\[1\] Indeed, an increased use of CTPA has been reported without clear benefit in terms of prognosis.This increased use is reportedly associated with potential overdiagnosis of PE, increased cost, length of ED stay, and side effects from both chest imaging and undue anticoagulant treatments. The standard diagnostic strategy for PE work up includes three steps with an initial evaluation of clinical probability, followed by D-dimer testing if indicated, followed by chest imaging if necessary - Computed tomographic pulmonary angiogram CTPA being the imaging modality of choice.

A large European prospective study has reported that the use of CTPA has constantly increased without change in the diagnostic yield. In order to reduce the use of CTPA, it has been validated that in patients with a low likelihood of PE, the D-dimer threshold for ordering CTPA can be raised at 1000 ng/ml. It has been validated that a low likelihood of PE can be determined either with the YEARS or the PEGeD clinical decision rules. These latter two include one common item being "Is PE the most likely diagnosis". A retrospective cohort study of 3330 patients reported that using this sole question of "Is PE the most likely diagnosis" can be safely used to raise the D-dimer threshold to 1000 ng/ml, and that this performs as well as YEARS and PEGeD. This simple question is easier to use by emergency physicians compared to complex ones, which are reportedly seldom used by emergency physicians. Therefore, the validation of the "PE unlikely" simple and straightforward decision rule could increase physicians' adherence and therefore limit the use of chest imaging.

The hypothesis of this prospective study is that the likelihood of PE assessed to elevate the DDimer threshold to 1000 ng/ml can be estimated by the sole question of "is PE the most likely diagnosis", and to validate a global simplified diagnostic strategy for PE in the ED.

The intervention will be the patient's management with a simplified global strategy. Whether PE is the most likely diagnostic will be assessed by the unstructured implicit clinician's estimation.

In patient with a clinical suspicion of pulmonary embolism: DDimer testing will be performed.

If the likelihood of PE is low (PE is not the most likely diagnosis), then threshold for DDimer testing will be 1000 ng/ml. If the likelihood of PE is high (PE is the most likely diagnosis), then the age-adjusted DDimer threshold will be applied.
