Emergency-physician ultrasound is good enough to screen for RV strain in PE

Design

Retrospective cohort comparing POCUS with consultative echocardiography

Population

194 ED patients with pulmonary embolism, 97 physician ultrasound operators

Primary outcome

Accuracy of POCUS for right-ventricular dysfunction vs consultative echo

Effect

Sensitivity 76.8%, specificity 85.9%, agreement 81.4% (kappa 0.63)

Right-ventricular dysfunction raises the risk in pulmonary embolism, but formal echocardiography is often slow to obtain. This study compared emergency-physician point-of-care ultrasound (POCUS) with cardiologist-read consultative echocardiography in 194 ED patients with PE, across 97 different physician operators.

Against consultative echo, POCUS was 76.8% sensitive and 85.9% specific for right-ventricular dysfunction, with 81.4% agreement (kappa 0.63), and it performed best when the dysfunction was moderate to severe. In other words, emergency physicians can reliably pick up the significant right-heart strain that drives escalation decisions.

The practice change is to use your own bedside scan to risk-stratify PE at presentation rather than waiting on a consultative study — while remembering that sensitivity of 77% means a normal POCUS does not exclude dysfunction, so confirm with formal echo when the stakes or suspicion are high.

• Emergency-physician POCUS was 77% sensitive and 86% specific for RV dysfunction in PE.
• Agreement with cardiologist echo was good and best for moderate-to-severe dysfunction.
• Use bedside POCUS to risk-stratify PE at presentation rather than awaiting formal echo.
• A normal POCUS does not exclude dysfunction — confirm with echo when suspicion is high.

Why it matters

It supports acting on your own ultrasound for PE risk stratification instead of waiting for a consultative echo.

Don't overread it

Retrospective, with 77% sensitivity and only moderate agreement — POCUS screens for RV dysfunction but cannot rule it out, especially when it is mild.

The statistics, in plain English

A sensitivity of 77% means roughly one in four cases of dysfunction is missed, so POCUS is better at confirming strain than excluding it; specificity of 86% means a positive scan is fairly trustworthy.
