Abstract

Background: The overall evidence base regarding delirium has been growing steadily over the past few decades. There has been considerable analysis of delirium concerning, for example, mechanically ventilated patients, patients in the general intensive care unit (ICU) setting, and patients with exclusively postoperative delirium. Nevertheless, there are few studies regarding delirium in a cardiovascular ICU (ICCU) setting and especially scarce literature about the particular features of delirium relating to patient age and gender.

Aim: We aimed to determine particular features of non-alcohol and other psychoactive substances induced delirium relating to patient age and gender in an ICCU setting.

Methods: An observational cross-sectional study was conducted to evaluate patients with delirium in a Lithuanian ICCU. From a sample of 19,007 ICCU admissions, 337 (1.8%) had documented delirium diagnosed through liaison and consultation with a psychiatrist and were included in the final analysis. The obtained data was then evaluated and analysed according to patients’ gender and four categorized age groups: <65 years, 65–74 years, 75–84 years, and ≥85 years.

Results: Female patients who experienced delirium demonstrated a higher prevalence of hypertension, hyponatraemia, heart failure, cardiac rhythm and conduction disorders, myocardial infarction (MI), and dementia. Men, who were on average seven years younger than women, significantly more often had hypokalaemia, double or triple-vessel coronary artery disease, as well as sepsis. Furthermore, MI, ST-segment elevated MI, and Killip class 4 were most frequent amongst patients less than 65 years of age. Moreover, the youngest patient group demonstrated the highest mortality.

Conclusions: Our investigation presented a number of associated peculiarities related to gender and age. It was shown that delirium is a severe complication that more often affects men amongst patients <65 years, while more frequently affects women in the age group of ≥85 years. Male patients <65 years who develop delirium should be treated with more caution, as they tend to have more serious forms of disorder and a poorer prognosis.
