Abstract

Delirium in intensive care units increases morbidity and mortality risk. The incidence and risk factors of delirium vary among studies. This study therefore aimed to determine the incidence and risk factors of delirium in Thai university-based surgical intensive care units. A multi-center, prospective cohort study was conducted. All patients who had been admitted to surgical intensive care units (SICU) between April 2011 and January 2012 were enrolled. Delirium was diagnosed using the Intensive Care Delirium Screening Checklists (ICDSC). The univariable and multivariable risk regression analyses were analyzed and presented as risk ratio (RR) and 95 % confidence interval (CI). The overall incidence of delirium was 3.6 % (162 of 4450, 95 % CI 3.09-4.19 %) whilst the incidences of delirium for patients being admitted ≤48 and >48 h were 0.7 % (21 of 2967, 95 % CI 0.41-1.01 %) and 8.3 % (141 of 1685, 95 % CI 7.04-9.68 %), respectively. The incidence of delirium on each study site was significantly different (range between 0 and 13.9 %, P < 0.001). Delirious patients had a significantly higher age (65.3 ± 15.6 versus 61.8 ± 17.3 years, P = 0.013), higher Acute Physiology and Chronic Health Evaluation II score (APACHE II score) (16 (12-23) versus 10 (7-15), P < 0.001), and higher sequential organ failure assessment score (5 (2-8) versus 2 (1-5), P < 0.001). The median duration of delirium was 3 (1-5) days. Delirious patients had significantly longer duration of ICU stay (8 (5-19) versus 2 (1-4), P < 0.001) and higher ICU mortality rate (23.5 versus 8.1 %, P < 0.001). Sepsis (RR = 3.70, 95 % CI 2.33-5.90, P < 0.001), exposure to sedative medications (RR = 3.54, 95 % CI 2.13-5.87, P < 0.001), higher APACHE II score (RR = 2.79, 95 % CI 1.98-3.95, P < 0.001), thoracic surgery (RR = 1.74, 95 % CI 1.09-2.78, P = 0.021), and emergency surgery (RR = 1.70, 95 % CI 1.09-2.65, P = 0.019) were independent risk factors of delirium in SICU. Sepsis, exposure to sedative medications, higher APACHE II score, thoracic surgery, and emergency surgery were independent risk factors of delirium in Thai university-based surgical intensive care units.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 15 January 2024.
All research outputs
#7,713,391
of 25,371,288 outputs
Outputs from Journal of Intensive Care
#311
of 579 outputs
Outputs of similar age
#110,357
of 395,281 outputs
Outputs of similar age from Journal of Intensive Care
#9
of 18 outputs
Altmetric has tracked 25,371,288 research outputs across all sources so far. This one has received more attention than most of these and is in the 69th percentile.
So far Altmetric has tracked 579 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 13.9. This one is in the 45th percentile – i.e., 45% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 395,281 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 71% of its contemporaries.
We're also able to compare this research output to 18 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 55% of its contemporaries.
