IntroductionWe assessed the efficacy of a brief, 8-h teaching program, using an objective structured clinical examination (OSCE) for the use of a pocket ultrasound device (echoscope) focused on bed side diagnosis of subclinical ascites in chronic liver disease.Patients and methodsTen cirrhotic patients, five with subclinical ascites and five without, were selected during ultrasound examination performed with a high performance equipment for screening of hepatocellular carcinoma. Five post graduate medical doctors residents in Gastroenterology or Internal Medicine underwent a brief, 8-h theoretical and hands-on examinations training. The methodology to assess the correct competence consisted in two phases defined by actions and answers to questions.ResultsThe evaluation of the technical efficacy was positive in all five students. The diagnostic efficacy for the ten patients examined consisted in no false positive diagnosis of ascites and one false negative.ConclusionsIn this preliminary experience, the use of a pocket ultrasound device (echoscope) for diagnosis of subclinical ascites in the context of a short structured teaching program and examination was efficient.RiassuntoAbbiamo valutato l’efficacia didattica di un breve corso della durata di 8 ore secondo l’esame clinico strutturato ed oggettivo (OSCE) per l’uso di un ecografo tascabile (ecoscopio) per la diagnosi al letto dell’ascite subclinica in pazienti con epatopatia cronica. Pazienti e Metodi: Dieci pazienti cirrotici, cinque con ascite subclinica e cinque senza, sono stati selezionati durante esami ecografici effettuati per la sorveglianza dell’epatocarcinoma con apparecchiatura ecografica di alto livello. Cinque medici specializzandi in Gastroenterologia o Medicina Interna hanno ricevuto otto ore di insegnamento teorico e pratico. Il metodo per accertare la competenza acquisita ha consistito in due fasi definite da specifiche azioni e risposte a domande. Risultati: La valutazione della efficacia tecnica ha dato risultato positivo in tutti gli studenti. La efficacia diagnostica sulla presenza o assenza di ascite subclinica nei dieci pazienti esaminati è risultata in nessun caso falso positivo e un caso falso negativo. Conclusioni: in questa esperienza preliminare l’uso di un ecografo tascabile appreso nel contesto di un breve programma didattico strutturato per la diagnosi di ascite subclinica si è dimostrato efficace.
