Triage: limitations in predicting need for emergent care and hospital admission

Annals of Emergency Medicine
J C BrillmanB J Skipper

Abstract

Little is known about the accuracy and reliability of current triage methods. We examined agreement among observers with regard to the need for ED care and the ability to predict at triage the need for admission to the hospital and compared these findings with admission rates after medical evaluation and management. We used a crossover design in which each subject was subjected to nurse or computer-guided triage first, the other type of triage second, and physician triage last. Our null hypothesis: Triage methods will yield the same results. Our patients were a consecutive sample of patients at the ED of a university-affiliated county referral center. Critically ill patients were excluded. Triage categorization was examined for interobserver agreement (kappa-statistic) and prediction of admission (sensitivity, specificity, and predictive values). Of the 5,106 patients enrolled in the study, 289 (6.2%) were admitted. With regard to the agreement of triage categorizations, we found kappa-values of .452 and .185, respectively, for physician triage compared with nurse (SE +/- .012) and computer triage (SE +/- .012)(P = .001 for the difference between the kappa values). Sensitivity and specificity in predicting admission were 41.3 a...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
