La formación de grado en enfermedades infecciosas, resistencia y uso de antibióticos desde la perspectiva de los estudiantes de Medicina

Introducción: Una de las principales herramientas para optimizar el uso de los antibióticos es la formación de los prescriptores. El objetivo de este trabajo es conocer la opinión de los estudiantes de Medicina españoles sobre la formación en enfermedades infecciosas. Material y métodos: Se distribuyó un cuestionario on line anonimizado entre estudiantes de sexto curso a través de distintos canales. El cuestionario incluyó 45 preguntas sobre conocimientos, actitudes y percepciones sobre el diagnóstico, resistencia antimicrobiana, uso de antibióticos y la formación de pregrado en enfermedades infecciosas. Resultados: Se recibieron un total de 441 encuestas de 21 facultades. Se obtuvieron 374 respuestas (84, 8%) de las 8 facultades más representadas, con una tasa de respuesta del 28, 9%. La mayoría de los alumnos se sentían preparados para identificar los signos clínicos de infección (418; 94, 8%) y para interpretar correctamente las pruebas de laboratorio (382; 86, 6%). Reconocieron saber elegir un antibiótico con seguridad sin consultar libros ni guías (178; 40, 4%). Solo 107 alumnos (24, 3%) consideraron haber recibido suficiente formación en el uso prudente de los antimicrobianos. Respecto a los métodos de aprendizaje, se percibieron como más útiles la discusión de casos clínicos, los rotatorios en servicios o unidades de enfermedades infecciosas y los talleres de pequeños grupos: se evaluaron favorablemente en un 76, 9; en un 76 y en un 68, 8% de los casos, respectivamente. Conclusión: Los estudiantes de Medicina se encuentran más seguros en el diagnóstico de enfermedades infecciosas que en el tratamiento antibiótico. Asimismo, sienten la necesidad de recibir mayor formación en antibioterapia y uso prudente en antibióticos. Introduction: One of the main tools to optimize antibiotics use is education of prescribers. The aim of this article is to study undergraduate education in the field of infectious diseases, antimicrobial resistance and antibiotic stewardship from the perspective of Spanish medical students. Material and methods: An anonymous online questionnaire was distributed among sixth grade students using different channels in Europe, within the ESGAP Student-Prepare survey. The questionnaire included 45 questions about knowledge, attitudes and perceptions about diagnosis, bacterial resistance, use of antibiotics and undergraduate training in infectious diseases. We present here the Spanish results. Results: A total of 441 surveys were received from 21 medical schools. A total of 374 responses (84.8%) were obtained from the 8 most represented faculties, with a response rate of 28.9%. Most students felt adequately prepared to identify clinical signs of infection (418; 94.8%) and to accurately interpret laboratory tests (382; 86.6%). A total of 178 (40.4%) acknowledged being able to choose an antibiotic with confidence without consulting books or guidelines. Only 107 (24.3%) students considered that they had received sufficient training in judicious use of antibiotics. Regarding learning methods, the discussion of clinical cases, infectious diseases units rotatories and small group workshops were considered the most useful, being evaluated favorably in 76.9%, 76% and 68.8% of the cases. Conclusion: Medical students feel more confident in the diagnosis of infectious diseases than in antibiotic treatment. They also feel the need to receive more training in antibiotics and judicious antibiotic use

Role of age and comorbidities in mortality of patients with infective endocarditis

Purpose: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. Methods: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015. Patients were stratified into three age groups:<65 years, 65 to 80 years, and = 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. Results: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 = 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients =80 years who underwent surgery were significantly lower compared with other age groups (14.3%, 65 years; 20.5%, 65-79 years; 31.3%, =80 years). In-hospital mortality was lower in the <65-year group (20.3%, <65 years;30.1%, 65-79 years;34.7%, =80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%, =80 years; p = 0.003).Independent predictors of mortality were age = 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI = 3 (HR:1.62; 95% CI:1.39–1.88), and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared, the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. Conclusion: There were no differences in the clinical presentation of IE between the groups. Age = 80 years, high comorbidity (measured by CCI), and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group
