Outpatient Management of Patients with PE – U.S. Practice Patterns

Written by Bo Stubblefield

In this US-based cohort study, the emergency department (ED) discharge rate of acute pulmonary embolism (PE) was <5%. The rate of outpatient PE management varied widely between institutions.

Why does this matter?
Outpatient management of patients with deep venous thrombosis (DVT) has been more widely accepted as a best practice, while adoption of outpatient management of low-risk patients with acute PE has lagged(1-5). Outpatient management for patients deemed low-risk by validated clinical decision tools (PESI, sPESI, and Hestia Criteria) leads to safe, efficacious, patient-centered, and cost-effective care (6-12). This practice is simplified by the use of direct oral anticoagulant medications (DOACs) (13-15), and supported by clinical trial evidence (16-20) and clinical practice guidelines from international societies (21-26). @LWestafer, et al. shed further light on this US practice pattern…

Let us repeat the mantra together:  “Low-risk PEs may be discharged. Low-risk PEs may be discharged. Low-risk PEs may be discharged…”
This was a retrospective cohort of 61,070 adult patients diagnosed with acute PE in 740 US hospitals. The primary outcome was initial disposition from the ED – discharge from the ED versus admission to an inpatient or observation unit. The discharge rate of acute PE was <5%. At 30 days, 1.3% had a bleeding-associated diagnosis, and rates of return to the ED were similar to prior studies (17.9%) with only 10.3% hospitalized. Unsurprisingly, the cost of inpatient management was higher (to the tune of a median 6x higher) than those discharged from the ED. The rates of outpatient PE management varied widely between institutions, and the hospital where a patient presented was one of the strongest predictors of a patient being admitted or discharged.

Despite the large body of clinical trial evidence and the support of practice guidelines, clinicians remain wary of discharging patients with PE. Clinicians who practice in the acute care setting should continue to become comfortable with risk stratification, anticoagulation, and discharge of low-risk PE.
