Prior studies of point-of-care ultrasound (POCUS) interpretation methods for identifying LAE utilized older echocardiographic reference ranges. OBJECTIVES: Compare the test characteristics of hospitalist-performed POCUS techniques for identifying LAE as compared to contemporary echocardiographic reference ranges. METHODS: Fully paired, comparative diagnostic accuracy study of two index tests applied to archived echocardiogram images: visual assessment of the left atrium to aorta diameter (LAE sign) and left atrial (LA) anteroposterior diameter >4 cm in the parasternal long axis view. The reference test was moderate to severe LAE by echocardiography-derived left atrial volumetric index. RESULTS: After exclusion criteria, 239 of 321 (74.5%) exams were included. The LAE sign had a sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 67.5%, 71.4%, 32.1%, and 91.6%. LA diameter of >4 cm had a sensitivity, specificity, PPV, and NPV of 87.5%, 75.9%, 42.2%, and 96.8%. The difference in sensitivity (p = .005) and specificity (p = .049) between the index tests was statistically significant. The diameter measurement had better positive and negative likelihood ratios (LR + 3.63, LR-0.16) than the LAE sign (LR + 2.36, LR- 0.46). CONCLUSIONS: Both POCUS techniques for diagnosing LAE performed reasonably well compared to current echocardiographic reference ranges, with LA diameter >4 cm having better sensitivity and specificity than visual estimation of the LAE sign. These tests can help identify patients at risk for cardiovascular disease who may benefit from echocardiogram referral.
