Abstract
The aim was to identify the incidence and protective and risk factors for delirium in mechanically ventilated patients in an intensive care unit. Prospective cohort carried out in a public intensive care unit, from September 2019 to February 2020. Results were initially described using absolute and relative frequency. Cox regression was used to identify protective and risk factors for delirium, considering a 95% confidence interval. Protective factors for delirium were the variables of the ABCDEF bundle: assessment, prevention and management of pain, choice of analgesia and sedation (dexmedetomidine), assessment, prevention and management of delirium, and family involvement. The risk factors were alcohol consumption, use of physical restraint, longer hospital stay and mechanical ventilation. The incidence of delirium identified is high and the risk factors deserve immediate intervention, as well as the use of the ABCDEF bundle is suggested to reduce the incidence of delirium in the unit. However, training and qualification of the multidisciplinary team are essential for the assessment and early diagnosis of delirium, as well as for the assessment of daily awakening, type of sedative used, daily decrease in sedation, mechanical ventilation time and permanence of patients in the intensive care unit.
