Delirium in the hospitalized elderly: evaluation of precipitating factor
Abstract
Objective: To evaluate the association of precipitating factors with the occurrence of delirium in hospitalized elderly. Method: Quantitative, longitudinal, exploratory study conducted in a public hospital in northern Paraná in patients aged 60 years or older. The sample collected was 315 elderly, of which 67 had delirium during the study. Patients with a minimum hospitalization of 48 hours were included, and the data collected with the elderly, companion, health professional or in the medical record, daily, during the first week of hospitalization or until hospital discharge, transfer, death or diagnosis of delirium. Results: In the logistic regression analysis, there was an association of delirium with the precipitating factors: longer hospital stay in the emergency room, physical restraint, presence of a companion, disease severity, changes in urea, creatinine and C-reactive protein, presence of infection; deprivation of natural light, use of oxygen therapy and urinary catheterization. There were 26 significant correlations between the precipitating factors associated with delirium triggering. There was an association of delirium with worsening prognosis, longer hospital stay and death. Conclusion: Multiprofessional interventions controlling the occurrence of precipitating factors may contribute to the reduction of delirium cases, impacting the length of hospitalization, morbidity and mortality of the hospitalized elderly.
