The eTRIAGE tool accurately predicts emergency department resource use and costs. This validated decision support system aligns patient acuity with healthcare resource allocation for improved efficiency.

Area of Science:

  • Emergency Medicine
  • Health Informatics
  • Health Services Research

Background:

  • Emergency department (ED) triage is crucial for prioritizing patient care based on urgency.
  • eTRIAGE is a web-based decision support tool utilizing the Canadian Triage and Acuity Scale (CTAS).

Purpose of the Study:

  • To validate the eTRIAGE tool by assessing its correlation with resource utilization and costs.
  • To determine if eTRIAGE accurately reflects patient acuity in an emergency setting.

Main Methods:

  • Collected data on CTAS scores, specialist consultations, CT scans, ED length of stay, disposition, and costs for 29,524 patients.
  • Utilized logistic regression, ANOVA, and Kruskal-Wallis tests to analyze correlations between CTAS scores and outcomes.
  • Employed a multivariate regression model to identify interactions and the association with cost.

Main Results:

  • eTRIAGE scores showed significant correlations with consultations, CT scans, length of stay, and disposition (p < 0.001).
  • Higher CTAS levels (1-2) were associated with increased odds of consultation, CT scan, and admission compared to CTAS 3.
  • Costs significantly correlated with acuity, with CTAS 1 patients incurring median costs of $2,690, demonstrating a clear cost-acuity relationship.

Conclusions:

  • eTRIAGE demonstrates strong predictive validity for resource utilization and associated ED and hospital costs.
  • The tool effectively measures patient acuity, supporting efficient resource allocation in emergency departments.
  • Future research should explore specific presenting complaints to further refine eTRIAGE's validity.
