Key result
Using the Sequential Probability Ratio Test, intensive care trainees required a variable number of scans (ranging from 13 to 25) to demonstrate greater than 90% accuracy in assessing left ventricular function compared to an expert.
Why the study?
Professional bodies require varying numbers of scans for focused cardiac ultrasound competence, and more individualized innovation in competency assessment was needed.
Can sequential testing help individualize competency assessments in focused cardiac ultrasound for intensive care trainees?

Can sequential testing help individualize competency assessments in focused cardiac ultrasound for intensive care trainees?
Sequential testing demonstrates that a variable number of scans (13-25) are required for trainees to achieve >90% accuracy in assessing LV function, suggesting it can help individualize focused cardiac ultrasound competency assessments.
Sequential testing may support individualized competency thresholds for focused cardiac ultrasound; leaves open effects on trainee performance and outcomes.

Walker et al. (2022) conducted an observational in Critical illness requiring focused cardiac ultrasound (n=270). Sequential Probability Ratio Test (SPRT) vs. Fixed number of scans was evaluated on Number of scans required to demonstrate >90% accuracy in assessing left ventricular function (95% CI 13-25). Using the Sequential Probability Ratio Test, intensive care trainees required a variable number of scans (ranging from 13 to 25) to demonstrate greater than 90% accuracy in assessing left ventricular function compared to an expert.
