About this study

A consecutive series of patients scheduled for elective cardiac surgery is included in the study. Delirium screening is performed using Intensive Care Delirium Screening Checklist. Preoperative cognitive state is evaluated with Mini-Mental State Examination. Information of possible risk factors is collected from patient's history and chart. The Snoring, Tiredness, Observed apnea, high blood Pressure-Body mass index (BMI), Age, Neck circumference and Gender questionnaire (STOP-BANG questionnaire) is used for obstructive sleep apnea screening.

Inclusion criteria

elective cardiac surgery
patient spends more than 1 day in the intensive care unit after the surgery

Exclusion criteria

refusal to participating in the study
documented severe central nervous system, cognitive or psychiatric disorder
unable to be screened with Intensive Care Delirium Screening Checklist up to 6th postoperative day (e.g. deeply sedated, intubated patients)

Treatment and study plan

Primary outcomes

Incidence of early postoperative delirium in intensive care patients after cardiac surgery

Time frame: Within 5 days after the surgery

Secondary outcomes

Perioperative risk factors for delirium after cardiac surgery

Time frame: Up to 5 postoperative days or occurence of delirium if it develops earlier

Preoperative risk factors include demographic data, comorbidities and standard preoperative laboratory and instrumental testing results as well as preoperative cognitive status evaluation, performed a day before the surgery. If the patient does not develop delirium, information on intraoperative and postoperative risk factors is collected up to discharge from intensive care unit or maximum 5 postoperative days, whichever happens earlier. If delirium occurs, data on risk factors is collected up to the beginning of delirium.
