ED Triage Acuity Scale (ESI):


Hospitals consistently struggle with triage accuracy, prolonged ED wait times and inappropriate disposition. The lack of consistent triage acuity category assignment and comprehension of a triage scale’s theoretical elements and implementation inevitably lead to poor outcomes, reduced efficiency in throughput, and increased risk to patients, staff, and hospital emergency departments. This course is designed specifically to improve triage acuity category assignment and appropriate disposition and treatment for presenting complaints in a highly interactive online environment.


  1. Summarize the advantages of a valid and reliable five-level triage acuity scale.
  2. Discuss causes of mistriage.
  3. Discuss the subjective nature of acuity scales.
  4. Distinguish goals, outcomes, and expectations associated with a valid and reliable five-level triage scale as they relate to all stakeholders.
  5. Differentiate elements of the Triage Assessment Process and their relationship before, during, and after assigning a triage acuity designation.
  6. Comprehensively define each acuity level and any pediatric specific considerations.
  7. Discuss factors associated with triage drift.
  8. Use a systematic approach to accurately and consistently prioritize patients by assigning triage acuities based upon clinical presentation, discriminators, criteria and any applicable algorithm
  9. Analyze factors that could escalate the triage acuity level.
  10. Verify the necessity of a triage reassessment policy and identify circumstances that may hinder meeting that policy.
  11. Employ triage acuity scale resource tools efficiently.
  12. Demonstrate the ability, using a comprehensive systematic evidence-based approach, to safely manage multiple patients arriving to triage simultaneously.
