Situación funcional tras un ictus y experiencia acumulada de una unidad de ictus / Functional outcome of stroke and the cumulative experience of a stroke unit

Objetivo: Los pacientes con un ictus tienen más probabilidades de supervivencia e independencia si son atendidos en una unidad de ictus. La información disponible en nuestro entorno acerca de la influencia del aprendizaje sobre estos resultados es escasa. Analizamos la situación funcional y mortalidad en nuestros pacientes en función de la experiencia acumulada en una unidad de ictus. Pacientes y métodos: Estudio de cohortes retrospectivo de pacientes ingresados en una unidad de ictus. Diferenciamos 2 grupos según el año de ingreso: grupo A (julio 2007-diciembre 2009) y grupo B (enero 2010-diciembre 2011), analizando la evolución precoz en función de la puntuación en la escala de ictus del National Institute of Health y la mortalidad al alta y la situación funcional a medio plazo en función de la mortalidad y estado funcional según la escala Rankin a los 3 meses. Resultados: Se incluyó a 1.070 pacientes. No se obtuvo diferencias entre los grupos ni en la evolución favorable (68,3% vs. 63,9), ni en la mortalidad tanto hospitalaria (5,1% vs. 6,6%), como a los 90 días (12,8% vs. 13,1%), siendo mayor el porcentaje de independientes a los 90 días en el grupo B (56,3% vs. 65,5%: p = 0,03). El análisis multivariante ajustado por subtipo de ictus y tratamiento fibrinolítico mantuvo la asociación entre la independencia y el período de ingreso. Conclusiones: La probabilidad de independencia funcional de nuestros pacientes aumentó con la experiencia acumulada de nuestra Unidad de Ictus sin observarse diferencias en la mortalidad

Objective: Patients with acute stroke are more likely to survive and achieve independence if they are treated in a stroke unit. Available information in our setting is scarce. We analyse the outcomes of our patients on the basis of cumulative experience in a stroke unit. Patients and methods: A retrospective cohort study of patients admitted to a stroke unit. We differentiate between two groups according to the year of admission: group A (July 2007-December 2009) and group B (January 2010-December 2011), analysing early outcome based on the score on the National Institute of Health stroke salce and mortality at discharge, and medium-term outcome in terms of mortality and functional status according to the modified Rankin scale at three months. Results: A total 1070 patients were included. There were no differences between groups with respect to favourable outcome (68.3% vs 63.9), hospital mortality (5.1% vs 6.6%), or 90-day mortality (12.8% vs 13.1%). The percentage of patients who were independent at 90 days was greater in group B (56.3% vs 65.5%, P = .03). In the multivariate analysis adjusted for stroke subtype and fibrinolytic therapy, the association between patient independence and admission period remained present. Conclusions: The probability of functional independence in our patients increased alongside accumulated experience in our stroke unit with no differences in mortality

Functional outcome of stroke and the cumulative experience of a stroke unit.
