Prospective Study for the Outpatient Treatment of Patients With Very Low Risk Acute Symptomatic Pulmonary Embolism. TRAMTEP Study.

Not applicable Interventional Clinica Universidad de Navarra, Universidad de Navarra · NCT05852119

This study is testing if outpatient treatment is safe and improves the quality of life for patients with low-risk pulmonary embolism who can go home within a day of diagnosis.

What this trial studies

This study evaluates the safety and quality of life for patients with very low-risk acute symptomatic pulmonary embolism (PE) who receive outpatient treatment. It involves 300 hemodynamically stable patients who will be discharged within 24 hours of diagnosis and treated with standard anticoagulant therapy. Data will be collected using the Computerized Registry of Thromboembolic Disease (RIETE) to ensure quality and facilitate analysis. The study will be conducted across 10 hospitals in Spain.

Who should consider this trial

Good fit: Ideal candidates are hemodynamically stable patients diagnosed with very low-risk acute symptomatic pulmonary embolism.

Not a fit: Patients who are hemodynamically unstable or have contraindications for anticoagulation will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could allow low-risk PE patients to be treated safely at home, improving their quality of life and reducing hospital stays.

How similar studies have performed: Other studies have shown promise in outpatient management of low-risk pulmonary embolism, suggesting this approach may be viable.

Eligibility criteria

Inclusion Criteria:

* Confirmation of suspected pulmonary embolism (PE) by multidetector chest angio computed tomography (CT), if a contrast-encircled partial intraluminal defect or complete pulmonary artery occlusion is demonstrated on two consecutive CT slices (13);
* Right ventricle (RV) diameter equal to or less than that of the left ventricle (LV) (RV/LV ratio ≤1) on chest CT angiography (see Study Procedures); and
* Negatively modified simplified Pulmonary Embolism Severity Index (sPESI) scale at the time of evaluation of the patient in the Emergency Department.

Exclusion Criteria:

* Inability to obtain informed consent
* Pregnancy
* Hemodynamic instability at diagnosis (defined by systolic blood pressure (SBP) \<90 mm Hg, indication of fibrinolytic treatment or inferior vena cava filter, need for vasoactive drugs at the discretion of the attending physician, cardiopulmonary resuscitation or orotracheal intubation)
* Contraindication for anticoagulation, at the discretion of the responsible physician;
* Estimated survival of less than 3 months
* Need for thrombectomy, vena cava filter insertion, or need for fibrinolytic treatment of the PE episode at the time of diagnosis
* Participation in a clinical trial for the treatment of venous thromboembolic disease
* Impossibility of follow up
