PurposeChest ultrasonography is currently a required element to achieve competence in general critical care ultrasound (GCCUS) which should be part of the training of every intensivist. We sought to assess the ability of resident novices in ultrasonography to identify and quantify unloculated pleural effusions in ICU patients after a limited training program.MethodsA total of 147 patients (mean age, 62 ± 17 years; simplified acute physiology score II, 35 ± 15; 78 % ventilated) with a suspected pleural effusion underwent a thoracic ultrasonography performed successively by a recently trained resident novice in ultrasound and by an experienced intensivist with expertise in GCCUS, considered as reference. Ultrasonographic examinations were performed randomly and independently. In the presence of a pleural effusion, the maximal interpleural distance was measured at the thoracic base.ResultsResidents performed a mean of 15 ± 9 examinations. Agreement between residents and experienced intensivists for the diagnosis of left- and right-sided pleural effusions was good to excellent [kappa 0.74 (95 % CI 0.63-0.85) and 0.86 (95 % CI 0.78-0.94), respectively)]. Agreement for the measurement of left and right maximal interpleural distance was excellent (intraclass concordance coefficient, 0.86 [95 % CI 0.77-0.91] and 0.85 [95 % CI 0.75-0.90], respectively). Mean bias for left and right interpleural distance was -0.3 mm (95 % CI -2.4, 1.8 mm) and -1.2 mm (95 % CI -3.4, 1.1 mm), respectively.ConclusionsAfter a focused training program, resident novices in ultrasound identify and quantify unloculated pleural effusions in ICU patients using chest ultrasonography with a good agreement with experts.
