Key result
Outpatient management of low-risk PE with DOACs yields <~1.5% short-term adverse event rates.
Why the study?
Patients with acute PE were historically routinely hospitalized, but advances in risk stratification and the availability of DOACs have shifted practice toward outpatient management for carefully selected low-risk patients.
Does outpatient anticoagulant management guided by validated risk stratification tools (PESI, sPESI, Hestia criteria) safely prevent short-term mortality, recurrent venous thromboembolism, and major bleeding in adults with low-risk acute pulmonary embolism?

Outpatient anticoagulant treatment is an appropriate option for carefully selected patients with low-risk acute pulmonary embolism when validated risk assessment tools (PESI, sPESI, Hestia criteria) are combined with clinical judgment and reliable follow-up.

Supports outpatient DOAC management of low-risk PE using validated tools; extends prior evidence but should not yet change practice without RCTs.
Acute pulmonary embolism (PE) remains an important cause of cardiovascular morbidity and mortality.Historically, patients with acute PE were routinely hospitalized for parenteral anticoagulation and clinical monitoring.Advances in risk stratification and the availability of direct oral anticoagulants (DOACs) have supported a shift toward outpatient management for carefully selected patients at low risk of adverse outcomes.This narrative review examines three validated clinical tools, the Pulmonary Embolism Severity Index (PESI), simplified PESI (sPESI), and Hestia criteria, and their roles in identifying adults with acute PE who may be suitable for home-based treatment.The review focuses on clinically relevant outcomes, including short-term mortality, recurrent venous thromboembolism, and major bleeding.Available evidence suggests that outpatient treatment appears to be an appropriate option for carefully selected patients with low-risk PE when medication access and reliable follow-up are available, provided that validated assessment tools are combined with evaluation of hemodynamic stability, bleeding risk, comorbid conditions, social circumstances, and access to follow-up care.Contemporary guidelines support structured risk assessment while emphasizing that clinical judgment and shared decision-making remain essential.Appropriate patient selection and reliable outpatient follow-up are central to safely expanding home-based treatment for acute PE.

Almaradweh et al. (2026) conducted a review in Acute pulmonary embolism. Outpatient management with direct oral anticoagulants (DOACs) guided by validated risk stratification tools (PESI, sPESI, Hestia criteria) vs. Inpatient management or alternative risk-stratification tools was evaluated on Short-term mortality, recurrent venous thromboembolism, and major bleeding. Outpatient management of low-risk acute PE using PESI, sPESI, or Hestia criteria with DOACs yields <1.5% 30-to-90-day rates of mortality, recurrent VTE, and major bleeding.
