Outpatient treatment of pulmonary embolism – a single-center experience

Abstract

Background: Pulmonary embolism (PE) is a common diagnosis in an emergency department. It also represents a large share of patients admitted to hospital wards. Patients with PE can be risk-stratified and discharged early from the emergency department. This results in better availability of hospital beds for other patients and a significant reduction of treatment costs for the healthcare system. This paper aims to describe the protocols used in our emergency department, with special emphasis on risk stratification, for adverse events and bleeding risk, treatment strategies, and outcomes for this type of protocol. Materials and methods: This paper is a retrospective analysis of patients discharged from the emergency department in a of two-year period (2020-2021) with a low-risk pulmonary embolism. Results: We have included in this study 42 patients discharged after a short-term observation from the emergency department (<24h) or short-term hospitalization; <24h). Ninety-one percent of patients were discharged with direct oral anticoagulant as a treatment for PE. We did not notice any adverse events (hemorrhage, progression of PE, or major cardiovascular issues). Conclusion: In the cohort of patients with PE, early discharge and outpatient treatment was safe and effective, with lower healthcare costs and almost no adverse events for patients.
