Abstract
Delirium is an acute disturbance of consciousness, with changes in cognitive functioning, inattention, perceptual disturbances and fluctuation of symptoms during the course of the day. In elderly patients, delirium is associated with longer hospital stays, increased mortality and an increased rate of institutional care. It is often reversible if the underlying cause is identified and treated. Objective: determine frequency of delirium in Intensive Care Unit (ICU) patients, aged 65 years old and over, that were hospitalized in the Special Care Unit of the Reina Sofía Clinic in Bogotá (Colombia) between January and June 2006. Also, clinic and sociodemographic characteristics were described. Methodology: case and control study based in a cohort, being the cohort ICU patients older than 65 years, of this group were extracted as cases subjects with diagnosis of delirium established by CAM scale (Confusion Assessment Method), and controls were patients without this diagnosis. Results: sample was 44 patients; frequency of delirium was 20.4%. Finding that certain variables, such as longer hospital stays, older patients and the diagnosis of an infection, had and statistically significant association to develop delirium. Conclusions: the main conclusion of the present study is that there exist clinical elements that are potentially changeable and that they could be associated with an increase in the risk of developing delirium during hospitalization. All these elements should be kept in mind in order to take care of the patients and to develop further studies that quantify the impact of these changes on the risk of delirium in the geriatric patients hospitalized in intensive care units.
