Resumo

Se realizó un estudio transversal, se incluyeron 3 residentes no cardiólogos y se les dio formación básica en ecocardiografía (horas teóricas 22, horas prácticas 65), con recomendaciones de la Sociedad Americana de Ecocardiografia y aportes del aprendizaje basado en problemas, con el desarrollo de competencia técnicas y diagnósticas necesarias, se realizó el análisis de concordancia entre residentes y ecocardiografistas expertos, se recolectaron 122 pacientes hospitalizados que cumplieran con los criterios de inclusión y exclusión, se les realizo un ecocardiograma convencional por el experto y una valoración ecocardiográfica por el residente, se evaluó la ventana acústica, contractilidad, función del ventrículo izquierdo y derrame pericárdico. La hipótesis planteada fue obtener una concordancia moderada. Resultados: Se analizó la concordancia entre observadores para la contractilidad miocárdica (Kappa: 0,57 p=0,000), función sistólica del ventrículo izquierdo (Kappa 0,54 p=0.000) siendo esta moderada por estar entre 0,40 – 0,60 y con una alta significancia estadística, para la calidad de la ventana acústica (Kappa: 0,22 p= 0.000) y presencia de derrame pericárdico (Kappa: 0,26 p= 0.000) se encontró una escasa concordancia ubicándose entre 0,20 – 0,40. Se estableció una sensibilidad de 90%, especificidad de 67%, un valor predictivo positivo de 80% y un valor predictivo negativo de 85% para el diagnóstico de disfunción sistólica del ventrículo izquierdo realizado por los residentes.

A cross-sectional study, three residents not included cardiologists and were given basic training in echocardiography (theoretical hours 22 hours 65 practices), with recommendations of the American Society of Echocardiography and contributions of problem-based learning, with the development of technical competence and necessary diagnostic, analysis of agreement between residents and experts echocardiography was performed, 122 hospitalized patients who met the inclusion and exclusion criteria were collected, they were performed by conventional echocardiography and echocardiographic assessment expert by the resident, the acoustic window, contractility and left ventricular function, pericardial effusion was assessed. The hypothesis was to obtain a moderate agreement. Results: The inter observer agreement for myocardial contractility (Kappa: 0.57 p = 0.000) was analyzed left ventricular systolic function (Kappa 0.54 p = 0.000) where this moderate to be between 0.40 to 0.60 and with high statistical significance for the quality of the acoustic window (Kappa: 0.22 p = 0.000) and presence of pericardial effusion (Kappa: 0.26 p = 0.000) was found poor concordance was reaching between 0.20 - 0.40. A sensitivity of 90%, specificity 67%, positive predictive value of 80% and a negative predictive value of 85% for the diagnosis of left ventricular systolic dysfunction performed by residents was established.
