Abstract
Objective: to describe the incidence of delirium at the intensive care units at Organización Sanitas Internacional from Bogotá and determine the related risk factors. Methods: This is a descriptive, prospective and multicentre study that was developed at 3 different intensive care units at Organización Sanitas Internacional Bogotá. Adult patients, 18 year-old and older with criteria for ICU were included. The diagnostic tool CAM-ICU was applied to these patients to detect the presence of delirium. The incidence of delirium in the population was later determined and the variables related to the incidence of the pathology were defined using multivariate analysis. Results: The incidence of delirum in the study population was 11.76% and it was prevalent in hypoactive form in 6.55% of the cases. The average duration of delirium was 2.8 +/- 0.7 days, which was diagnosed in average to 4.27 +/- 1.8 days since entry to the unit. The average age of the patients who developed delirium was 70 years old vs. 62 years old for those who did not develop delirium. No statistical difference in terms of gender, mortality, infection, cardiovascular disease, cancer, trauma, neurological disease and APACHE II was found. Patients who enter the unit because of pulmonary pathology and postoperative patients presented a higher level of delirium which may be related to the use of mechanical ventilation. The relation between development of delirium and the need for sedation and analgesia, particularly in relation to benzodiacepines, were documented. Conclusions: the incidence of delirium at the intensive care units at Organización Sanitas Internacional during the period of March 1st and November 31st 2010 was 11.76%. The conditions related with the development of delirium were: the needing of sedation and analgesia, use of benzodiacepines, needing of mechanical ventilation, pulmonary and surgical pathology. Similarly, the number of days of stay at the unit were higher in the group that developed delirium, however the mortality was not affected due to the presence of such condition.
