Exploring the Predictors of Emergency Department Triage Acuity Assignment in Patients With Sepsis

Abstract

Background and purpose

Evidence suggests that septic patients, who require prompt medical attention, may be undertriaged, resulting in delayed treatment. The purpose of this study was to examine patient and contextual variables that contribute to high- versus low-acuity triage classification of patients with sepsis.

Methods

Data were abstracted from the medical records of 154 adult patients with sepsis admitted to hospital through a Canadian Emergency Department. Logistic regression was used to explore the predictors of triage classification.

Results

Language barriers or chronic cognitive impairment (odds ratio 5.7; 95% confidence interval 2.15, 15.01), acute confusion (odds ratio 3.4; confidence interval 1.3, 8.2), unwell appearance (odds ratio 3.4; 95% confidence interval 1.7, 7.0), and hypotension (odds ratio 0.98; confidence interval 0.96, 1.0) were predictive of higher acuity classification. Temperature, heart rate, respiratory rate, and contextual factors were not related to triage classification.

Conclusions

Several patient-related factors were related to triage classification. However, the finding that temperature and heart and respiratory rates were not related to triage classification was troubling. Our findings point to a need for enhanced education for triage nurses regarding the physiological indices of sepsis. The sensitivity of the Canadian Triage Assessment Scale, used in Canadian Emergency Rooms, also needs to be examined.
