Aprendizaje basado en la simulación: valoración de los objetivos docentes en un programa de abdomen agudo y oclusión intestinal en cirugía general / Simulation-based learning: assessment of the teaching objectives in a program of acute abdomen and intestinal occlusion in general surgery, in medicine degree students

Introducción y objetivo: Analizar el logro de los objetivos docentes desarrollados durante el escenario de los casos de simulación a través de la valoración del profesor, los participantes observadores y quien realiza la propia simulación. Sujetos y métodos: Estudio observacional, prospectivo, descriptivo y unicéntrico, realizado con estudiantes de tercer curso de Medicina de la Universitat Autònoma de Barcelona. Se evalúan los objetivos docentes para cada caso clínico simulado por parte de los estudiantes que realizan la simulación, los observadores y el profesor. La evaluación numérica sigue una escala de tipo escala visual analógica y la categórica los clasifica en conseguidos, parcialmente conseguidos y no conseguidos. El estado nervioso y la comodidad de los alumnos también se evalúan numéricamente. Resultados: Se ha registrado la valoración de los objetivos de 929 participantes. La evaluación de los objetivos tiene un valor medio superior a 7 para cada uno de ellos. Existe una diferencia de 1,5-2 puntos en la valoración media entre el primer caso y el último, y no hay ningún alumno que no consiga los objetivos en el último caso. Se describe un estado de nervios alrededor de 4,5 y de comodidad alrededor de 7, sin diferencias entre los distintos evaluadores. Conclusiones: El logro de los objetivos se consigue de forma notable. Entre el primer caso y el último existe una significativa diferencia en el grado de obtención de los objetivos. No hay una relación entre el estado emocional de los participantes y la consecución de los objetivos.(AU)

Introduction and aim: To analyze the achievement of the educational objectives developed during the scenario of the simulation cases through the assessment of the teacher, the observer participants and the person who performs the simulation itself. Subjects and methods: Observational, prospective, descriptive and single-center study, carried out with 3rd year Medicine students at the Universitat Autònoma de Barcelona. The teaching objectives for each simulated clinical case are evaluated by the students who carry out the simulation, the observers and the teacher. The numerical evaluation follows a VAS-type scale and the categorical one classifies them as achieved, partially achieved and not achieved. The nervous state and comfort of the students are also evaluated numerically. Results: The evaluation of the objectives of 929 participants has been registered. The evaluation of the objectives has an average value greater than 7 for each one of them. There is a difference of 1.5-2 points in the average assessment between the first case and the last, with no student not achieving the objectives in the last case. A state of nerves around 4.5 and comfort around 7 is described, with no differences between the different evaluators. Conclusions: The achievement of the objectives is achieved in a remarkable way. Between the first case and the last, there is a significant difference in the degree of achievement of the objectives. There is no relationship between the emotional state of the participants and the achievement of the objectives.(AU)

Single-dose intravenous ferric carboxymaltose infusion versus multiple fractionated doses of intravenous iron sucrose in the treatment of post-operative anaemia in colorectal cancer patients: a randomised controlled trial.

BACKGROUND: Recent clinical guidelines suggest that treatment of postoperative anaemia in colorectal cancer surgery with intravenous iron reduces transfusion requirements and improves outcomes. The study aimed at comparing two intravenous iron regimens in anaemic patients after colorectal cancer surgery. MATERIALS AND METHODS: This was a single-centre, open-label, randomised, controlled trial in patients undergoing elective colorectal cancer surgery. Patients with moderate to severe anaemia (haemoglobin [Hb] <11 g/dL) after surgery were randomly assigned 1:1 to receive ferric carboxymaltose (FC; 1,000 mg, single dose) or iron sucrose (IS; 200 mg every 48 hours until covering the total iron deficit or discharge). Randomisation was stratified by Hb level: <10 g/dL (Group A) or ≥10-10.9 (Group B). The primary endpoint was the change in Hb concentration at postoperative day 30. Secondary endpoints included iron status parameters, transfusion requirements, complications, and length of hospital stay. RESULTS: From September 2015 to May 2018, 104 patients were randomised (FC 50, IS 54). The median intravenous iron dose was 1,000 mg and 600 mg in the FC and IS groups, respectively. There were no between-group differences in mean change in Hb from postoperative day 1 to postoperative day 30 (FC: 2.5 g/dL, 95% CI: 2.1-2.9; IS: 2.4 g/dL, 95% CI: 2.0-2.8; p=0.52), in transfusion requirements or length of stay. The infection rate was lower in the FC group compared with the IS group (9.8% vs 37.2%, respectively). DISCUSSION: The administration of approximately 500 mg of IS resulted in an increase in Hb at postoperative day 30 similar to that of 1,000 mg of FC, but it was associated with a higher infection rate. Future research will be needed to confirm the results, and to choose the best regime in terms of effectiveness and side effects to treat postoperative anaemia in colorectal cancer patients.
