Valoración de la concordancia entre la escala CAM-ICU y la nursing delirium screening scale en el postoperatorio de cirugía cardiaca en una unidad de críticos / Assessment of concordance between CAM-ICU scale and nursing delirium scale in postoperative period of ICU patients after cardiac surgery

Objetivo: Evaluar la concordancia entre la escala de valoración del delirio CAM-ICU y la Nursing Delirium Screening Scale (NDSS) en el postoperatorio de cirugía cardíaca. Material y métodos: Estudio prospectivo en hospital terciario con selección consecutiva de pacientes postoperados de cirugía cardiaca. Durante la estancia en la Unidad de críticos se administraron las escalas CAM-ICU y NDSS por el mismo investigador. Se realizó estadística descriptiva de variables demográficas y factores de riesgo preoperatorios de delirio. La concordancia se evaluó mediante el índice Kappa. Resultados: Se incluyeron 106 pacientes, realizándose 214 valoraciones. La incidencia de delirio con la escala CAM-ICU fue del 8,4%, y en la NDSS del 16,8%. La concordancia expresada por el índice Kappa fue de 0,541. Conclusiones: La concordancia entre la escala CAM-ICU y la NDSS en el postoperatorio de cirugía cardiaca y durante la estancia en la Unidad de Críticos es baja. Actualmente se recomienda la utilización de la CAM-ICU en este contexto, no debiendo sustituirse por la NDSS

Objective: To evaluate concordance between the scale of delirium assessment CAM-ICU and the Nursing Delirium Screening Scale (NDSS) in postoperative cardiac surgery. Material and methods: Prospective study in tertiary hospital with consecutive selection of patients after cardiac surgery. During the stay in the Intensive Care Unit, CAM-ICU and NDSS were administered by the same researcher. For demographic and preoperative risk factors of delirium, descriptive statistical analysis was performed. Concordance was assessed using kappa index. Results: 106 patients were included, performing 214 evaluations. Incidence of delirium with the CAM-ICU scale was of 8.4%, and of 16.8% with NDSS. The concordance expressed by the index Kappa was of 0.541. Conclusions: The concordance between the CAM-ICU scale and the NDSS in the postoperative cardiac surgery and during the stay in the Intensive Care Unit is low. Currently, the use of the CAM-ICU was recommended in this context, but it must not be replaced for the NDSS
