Limited data exist on advanced critical care echocardiography (CCE) training programs for intensivists. We sought to describe a longitudinal echocardiography program and investigate the effect of distributed conditional supervision vs predefined en-bloc supervision, as well as the effect of an optional echocardiography laboratory rotation, on learners' engagement. ⋯ Trainees perceived lack of time and limited access to supervision as major barriers to course completion. Nevertheless, successful portfolio completion was related to factors other than protected time in the echocardiography laboratory or unconditional direct supervision in ICU. Further research is needed to better understand the factors promoting success of CCE training programs.

Using machine learning, we developed a proprietary ultrasound software called the Spine Level Identification (SLIDE) system, which automatically identifies lumbar landmarks in real time as the operator slides the transducer over the lumber spine. Here, we assessed the agreement between SLIDE and manual palpation and traditional lumbar ultrasound (LUS) for determining the primary target L3-4 interspace. ⋯ gov (NCT02982317); registered 5 December 2016.
