Studies have reported the usefulness and tolerability in practice of abdominal ultrasound performed by non-radiologists in various clinical situations. This prospective observational single-center study included 184 patients hospitalized in an internal medicine department who underwent conventional abdominal ultrasound. A medical resident with basic training performed point-of-care clinical ultrasound using a pocket-sized device. The concordance obtained between the researcher and the radiologist was good (k >0.6) for the gallbladder, splenomegaly, longitudinal diameter of the kidney, presence of renal cysts and hydronephrosis. The specificity was >90% for all parameters assessed except normal renal size. A negative predictive value >90% was obtained for all variables studied except the presence of hepatic space-occupying lesions and gallbladder pathology, the negative predictive values for which were >80%. A positive predictive value >80% was obtained for all of these variables, except the presence of adenopathies, hepatomegaly, space-occupying lesions, echogenicity and/or enlargement of the biliary tract, left renal atrophy and right renal masses. We conclude there was a high concordance between a conventional abdominal study and that performed with a pocket-sized ultrasound device after a brief learning curve.
