Descriptors used for LILACS, MedLine and PubMed were delirium and intensive care unit, while for the CINAHL database, delirium and intensive care were used. From 293 articles, 35 were selected. The aspects analyzed disclosed, different types of delirium in different intensive care units. Variation in sensitivity was of 93% to 100% and variation in specificity, 89% to 100% of the Confusion Assessment Method for Intensive Care Unit, an important tool for detection, characterization and control of delirium and its impact. The aspects of delirium studied by means of the Confusion Assessment Method for Intensive Care Unit were: the performance index, identification, management, cost of treatment, morbidity and mortality due to delirium.
