In the emergency department, the first medical decision isn’t made by a doctor—it’s made at triage.
That initial classification, often by a nurse or advanced practice provider, determines how quickly a patient is seen, whether they get immediate diagnostics, and sometimes, whether they live or die. In litigation, it’s increasingly where plaintiff attorneys start their story.

A 2023 BMJ Quality & Safety study found that triage misclassification contributed to diagnostic delay in nearly 18% of ED malpractice cases, most often in patients with subtle presentations of sepsis, stroke, or myocardial infarction. The liability doesn’t stop with the triage nurse; it extends to how the hospital structures and supervises its triage system.

In Evans v. Memorial Health (2024), a 62-year-old woman with abdominal pain and tachycardia was assigned an ESI level 4: “non-urgent.” She waited nearly three hours before being evaluated and was later found to be in septic shock. The plaintiff’s attorney argued not just negligence in triage judgment, but corporate negligence for lack of oversight: there was no policy for mandatory re-triage when vital signs changed, and no secondary nurse review. The jury agreed, awarding $4.9 million.

Triage liability arises from two key failures:

  1. Systemic design flaws: inadequate training, absent re-evaluation triggers, or delegation of triage to inexperienced staff. 
  2. Documentation gaps:  missing rationale for triage level, absent physician notification of abnormal vitals, or lack of re-assessment intervals. 

Best practices now emphasize “dynamic triage,” where patient acuity is re-evaluated at set intervals or when vitals change. The ACEP Clinical Policy (2023) and ENA Triage Standards (2022) recommend institutional policies that define supervision, documentation, and escalation pathways.

From a medicolegal standpoint, triage errors often reflect not bad judgment, but bad systems – hospitals that prioritize throughput metrics over clinical vigilance. When attorneys reconstruct timelines, those first few minutes of triage often become the strongest evidence of neglect.

In the courtroom, the triage sheet is small, but it carries enormous weight.
