Teaching vs learning: Impact of deliberate practice and formative feedback on developing point of care ultrasound skills.

Extended exposure to POCUS over a 4-week rotation with direct and indirect formative feedback can explain difference in scores on psychomotor skills assessments. Trainees scored similarly on the written assessment with or without a POCUS rotation. Training through didactic and workshop experiences may be sufficient to learn the cognitive aspects, but not psychomotor skills required for POCUS.
