Hospitalization or Out-treatment ManagEment of Patients With Pulmonary Embolism: a Randomized Controlled Trial


Brief description of study

Several studies have demonstrated the possibility of outpatient management or early discharge for certain patients presenting acute pulmonary embolism (PE), providing a suitable structure is in place.

The approach featured in the most recent guidelines on acute PE of the European Society of Cardiology, refers to an all-cause mortality risk assessment using the Pulmonary Embolism Severity Index (PESI) score or the simplified PESI score (sPESI). The sPESI takes into account demographics (age), patient history (cancer, cardiac or respiratory disease), and clinical data (systolic blood pressure, heart rate, oxygen saturation). Outpatient care is offered to low-risk patients, providing that all the conditions pertaining to start anticoagulant treatment and follow-up at home are met.

An alternative approach based on a list of simple criteria has been developed as the one used in HESTIA study. The main criteria included in the HESTIA rule consist of absence of the following: hemodynamic instability, need for oxygen therapy, high-risk of hemorrhage, renal or liver failure, or other medical or social conditions requiring hospitalization.

The investigators hereby propose comparing these two approaches in an open-label, controlled randomized international trial with blinded adjudication of endpoints.

The main objective is to demonstrate, in normotensive PE patients, that a strategy based on the HESTIA rule compared to a strategy based on the simplified PESI score is at least as safe as regards the 30-day-rate of adverse events (recurrent VTE, major bleeding or death).

The major secondary objectives are to demonstrate, in normotensive PE patients, that a strategy based on the HESTIA rule compared to a strategy based on the simplified PESI score is more effective :

  • As regards the rate of patients eventually managed as outpatients.
  • As regards the rate of patients, in theory, eligible for outpatient care,

Detailed Study Description

All patients admitted in the Emergency Department of the participating centres and diagnosed with PE will be eligible and assessed for potential inclusion.

Included patients will be randomized into two groups (1:1) and stratified by centre. Data will be recorded in a computerized case report form (e-CRF) enabling the randomization.

The HESTIA group will receive outpatient care proposal based on HESTIA criteria. The sPESI group will receive outpatient care proposal based on the simplified PESI score. Any reason for management (hospitalization or outpatient treatment) not based on the recommendation will be explained and documented in the e-CRF.

Follow-up will occur within 72 hours after inclusion, at 14 days, 1 month, and 3 months in both groups to gather clinical event data (recurrent VTE, major bleeding, death), treatment data, unscheduled hospitalizations and patient satisfaction assessment results.

The major objectives will test HESTIA based strategy versus sPESI based strategy in a hierarchical approach:

  • step 1: non-inferiority analysis on the rate of adverse events,
  • if yes, step 2: superiority analysis on the rate of patients managed as outpatients,
  • if yes, step3: superiority analysis on the rate of patients, in theory, eligible for outpatient care.
