Task-shifting to nonexperts using artificial intelligence-guided point-of-care ultrasound: a cohort study of patient selection, image quality, and learning curves.

A standardized training protocol included online material, lab attendance for 1 day, and online mentoring.

Body surface area (body surface area) [OR 0.16 (0.05;0.50), P = 0.002] and hypertension [OR 0.50 (0.27;0.93), P = 0.03] were associated with diagnostic image quality in the apical window, whereas only hypertension [OR 0.43 (0.20;0.88), P = 0.024] was associated with diagnostic quality in the parasternal window.
