Delirium is common and dangerous among elderly inpatients. Yet it is underdiagnosed and thus undertreated. This study aims to test the diagnostic characteristics of a noninvasive point-of-care device with two-channel (bispectral) electroencephalography (EEG) for the screening of delirium in the hospital.
Patients admitted to the University of Iowa Hospitals and Clinics were assessed for the presence of delirium with a clinical assessment, the Confusion Assessment Method for Intensive Care Unit and Delirium Rating Scale. Subsequently, we obtained a 10-minute bispectral electroencephalography (BSEEG) recording from a hand-held electroencephalogram device during hospitalization. We performed power spectral density analysis to differentiate between those patients with and without delirium.
Initially 45 subjects were used as a test dataset to establish a cut off. The BSEEG index was determined to be a significant indicator of delirium, with sensitivity 80% and specificity 87.7%. Additional independent validation dataset with 24 patients confirmed the validity of the approach, with a sensitivity of 83.3%, specificity of 83.3%.
In this pilot study, (bispectral) electroencephalography was able to distinguish delirious patients from non-delirious patients. Our data showed the feasibility of this technology for mass screening of delirium in the hospital. This article is protected by copyright. All rights reserved.
This research output has an Altmetric Attention Score of 13. 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 February 2023.
All research outputs
#3,671,066
of 34,526,284 outputs
Outputs from Psychiatry & Clinical Neurosciences
#220
of 2,041 outputs
Outputs of similar age
#56,661
of 393,495 outputs
Outputs of similar age from Psychiatry & Clinical Neurosciences
#1
of 13 outputs
Altmetric has tracked 34,526,284 research outputs across all sources so far. Compared to these this one has done well and is in the 89th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,041 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.6. This one has done well, scoring higher than 89% of its peers.
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 393,495 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 85% of its contemporaries.
We're also able to compare this research output to 13 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 92% of its contemporaries.
