Lung ultrasonography (LUS) is an accurate method of estimating lung congestion but there ongoing debate on the optimal number scanning points. The aim present study was to compare reproducibility (i.e. interobserver agreement) and feasibility time consumption) two most practiced protocols in patients hospitalized for acute heart failure (AHF). This prospective trial compared 8- 28-point LUS protocols. Both were performed by expert-novice pair sonographers at admission after 4 6 days admitted AHF. A structured bio-clinical evaluation simultaneously carried out treating physician. primary outcome agreement estimated kappa statistics. Secondary outcomes included spent image acquisition interpretation. During period, 43 underwent a total 319 exams. Expert-novice moderate substantial follow-up 8-point protocol (weighted 0.54 0.62, respectively) with no significant difference 0.51 0.41; P value comparison 0.74 0.13 follow-up). required significantly less (mean - 3.6 min experts, 5.1 novices) interpretation (- 6.0 experts 6.3 novices; < 0.001 all comparisons). Similar differences observed follow-up. In conclusion, shown be timesaving similar when protocol. It should preferred evaluating AHF inpatients.
