Emergency Severity Index (ESI) defines triage levels based on which two factors?

The main idea is that Emergency Severity Index uses a five-level scale that blends two factors: how sick the patient appears (illness severity or acuity) and how many clinical resources the patient is expected to need to treat them (such as labs, imaging, medications, or procedures). This combination drives the triage level and the treatment order. For the most urgent cases, immediate life-saving interventions are required, placing them at the highest level. If a patient is worried but not in immediate danger, their level depends on whether the anticipated resources are few or many. In short, acuity and resource use together determine how quickly a patient is seen and what level of care they’ll receive, rather than age, a single symptom, or ignoring resource needs.
