Abstract
Introduction: We thought that the presence of delirium precipitating factors, added to risk factors, may significantly increases the risk to develop delirium during hospitalization.
Objetives: For this reason the study was designed, in which patients were included over a 2 years period in order to identify the most frequent predisposing and precipitating delirium factors in our fourth category hospital. Methods: Over a two year period in the Hospital San Ignacio in Bogota, an observational, analytical and prospective case-control study was designed. Fifty-six (56) patients of ages more than 60 years old were included. Twenty-eight (28) patients developed delirium during hospitalization. In order to analyze predisposing and precipitating delirium factors in these patients, we compared this group with an equal number of twenty-eight (28) control patients with no delirium criteria.
Results and conclusions: It was found that among the most frequent predisposing factors were the use of lenses, base Chronic Obstructive Pulmonary Disease (COPD), Congestive Heart Failure (CHF), base cancer and medicine use, but it was not significantly determined that these factors increased the risk of delirium, while among the precipitating factors, the presence of infections, particularly urinary tract infection and pneumonias increased the risk significantly by an OR of 3.66 and a p = 0.028.
