Resumen
Objetivo: Evaluar el efecto inmediato del uso de vodcasts (vídeos a demanda) sobre el desempeño cognitivo en reanimación cardiopulmonar (RCP) y sobre la motivación de estudiantes de Medicina, mediante un diseño cuasi-experimental de pre-test y post-test. Métodos: Estudio cuasi-experimental de tipo pre-test y post-test, realizado con 14 estudiantes de tercer año de Medicina. Los estudiantes vieron un vodcast sobre RCP dividido en tres capítulos, y el desempeño cognitivo fue evaluado con preguntas de opción múltiple antes y después de la intervención. La motivación se midió con la versión brasileña validada del Instructional Materials Motivation Survey (IMMS-BRV), en cuatro dimensiones: interés, confianza, atención y expectativa. El estudio fue aprobado por el Comité de Ética en Investigación. Resultados: Hubo mejora significativa del desempeño tras la intervención, con tamaño de efecto elevado. Los estudiantes que dedicaban de una a dos horas diarias a los medios digitales para estudios médicos presentaron mayor ganancia y mayor puntuación en el post-test que aquellos que declararon más de tres horas. La motivación fue elevada y homogénea en las cuatro dimensiones, sin diferencias significativas entre ellas, y no se asoció con el desempeño. Conclusión: En la muestra evaluada, el uso de vodcasts se asoció a una mejora inmediata del desempeño cognitivo en RCP; los hallazgos deben interpretarse con cautela debido al tamaño reducido de la muestra y al origen en una única institución.
