Discharge from the emergency department and outpatient clinic in cancer patients with acute symptomatic and incidental pulmonary embolism: A multicenter retrospective cohort study

JTH in Clinic: management of low-risk pulmonary embolism

Pulmonary embolism (PE) is a common cardiovascular disease diagnosis in emergency departments that can be associated with significant morbidity and mortality. One of the first steps after diagnosing PE is to risk stratify for adverse outcomes using risk scores such as PE Severity Index and European Society of Cardiology risk scheme. While intermediate- and high-risk PE patients should be admitted to the hospital, there is increasing evidence to support early discharge and home-based anticoagulation therapy for low-risk patients. The Hestia criteria encompass many of the clinicians' considerations for who may be suitable for early discharge, considering both medical and social factors. Additionally, professional guidelines have provided algorithms on determining which low-risk patients may be suitable. Despite this, low-risk acute PE patients are still often admitted for inpatient treatment. In this review, we present a case-based approach on how to risk stratify and evaluate patients who may be good candidates for early discharge and home therapy.

Home Treatment for Active Cancer Patients With Low-Risk Pulmonary Embolism - A Predetermined Companion Report From the ONCO PE Trial

BACKGROUND

Patients with appropriately selected low-risk pulmonary embolism (PE) can be treated at home, although it has been controversial whether applies to patients with cancer, who are considered not to be at low risk.Methods and Results: The current predetermined companion report from the ONCO PE trial evaluated the 3-month clinical outcomes of patients with home treatment and those with in-hospital treatment. The ONCO PE trial was a multicenter, randomized clinical trial among 32 institutions in Japan investigating the optimal duration of rivaroxaban treatment in cancer-associated PE patients with a score of 1 using the simplified version of the Pulmonary Embolism Severity Index (sPESI). Among 178 study patients, there were 66 (37%) in the home treatment group and 112 (63%) in the in-hospital treatment group. The primary endpoint of a composite of PE-related death, recurrent venous thromboembolism (VTE) and major bleeding occurred in 3 patients (4.6% [0.0-9.6%]) in the home treatment group and in 2 patients (1.8% [0.0-4.3%]) in the in-hospital treatment group. In the home treatment group, there were no cases of PE-related death or recurrent VTE, but major bleeding occurred in 3 patients (4.6% [0.0-9.6%]), and 2 patients (3.0% [0.0-7.2%]) required hospitalization due to bleeding events.

CONCLUSIONS

Active cancer patients with PE of sPESI score=1 could be potential candidates for home treatment.
