Key result
Deep learning-guided POCUS by novice nurses achieves ~88% adequate scan quality, matching experienced physicians.
Why the study?
Abdominal aortic aneurysm often remains undetected until rupture due to limited access to diagnostic ultrasound.
Does deep learning-guided POCUS by novice nurses achieve comparable ultrasound scan quality to physician-performed scans for AAA screening in patients ≥65 years old?
Cross-Sectional (n=184)
Single-blind (outcome assessors)
No
Does deep learning-guided POCUS by novice nurses achieve comparable ultrasound scan quality to physician-performed scans for AAA screening in patients ≥65 years old?
Deep learning-guided POCUS enables novice nurses to acquire diagnostic-quality abdominal aortic ultrasound scans comparable to experienced physicians, potentially democratizing AAA screening.

DL-guided novices matched physician AAA scan quality; supports broader screening access but remains hypothesis-generating pending RCTs.
Abdominal aortic aneurysm (AAA) often remains undetected until rupture due to limited access to diagnostic ultrasound. This trial evaluated a deep learning (DL) algorithm to guide AAA screening by novice nurses with no prior ultrasonography experience. Ten nurses performed 15 scans each on patients over 65, assisted by a DL object detection algorithm, and compared against physician-performed scans. Ultrasound scan quality, assessed by three blinded expert physicians, was the primary outcome. Among 184 patients, DL-guided novices achieved adequate scan quality in 87.5% of cases, comparable to the 91.3% by physicians (p = 0.310). The DL model predicted AAA with an AUC of 0.975, 100% sensitivity, and 97.8% specificity, with a mean absolute error of 2.8 mm in predicting aortic width compared to physicians. This study demonstrates that DL-guided POCUS has the potential to democratize AAA screening, offering performance comparable to experienced physicians and improving early detection.

Chiu et al. (2024) conducted a cross-sectional in Abdominal aortic aneurysm (n=184). Deep learning-guided point-of-care ultrasound by novice nurses vs. Physician-performed point-of-care ultrasound without AI guidance was evaluated on Ultrasound scan quality (rate of qualified videos) (p=0.310). Deep learning-guided point-of-care ultrasound by novice nurses achieved adequate scan quality in 87.5% of cases, comparable to the 91.3% achieved by experienced physicians (p=0.310).
