Bias Analysis: A Patient With Slurred Speech Triaged as Intoxicated Before the Glucose Was Checked, What the Triage Nurse Could and Could Not Perceive in the First Minutes and Why the First Category Held

The Case

At the triage desk of an emergency department that belongs to no real hospital, a man in his fifties arrived on a Friday evening, brought by a security guard from a nearby parking garage. He was unsteady, his speech was slurred and he smelled faintly of something the guard described as alcohol. He could not give a clear history. The triage nurse assigned him a lower acuity level with a note reading "likely ETOH" and sent him to a hallway bed to wait. Forty minutes later, a second nurse checked his blood glucose as part of a routine set of vital signs. It was 38 mg/dL. He received glucose and recovered within minutes. He had type 1 diabetes, had skipped dinner after a long shift and had taken his evening insulin. The smell was likely acetone or simply misidentified.

What the Nurse Could Perceive

In the first minutes, the nurse had a cluster of cues: unsteadiness, slurred speech, a reported smell of alcohol, a Friday evening arrival and a security escort from a parking garage. She did not have a glucose reading, a medical history or a medical alert bracelet, which he was not wearing. Every cue she had was consistent with intoxication. Several were also consistent with hypoglycemia, stroke or head injury, but the cluster as a whole matched the picture of intoxication she had seen many times on Friday nights.

How the First Category Formed

Tversky and Kahneman (1974) described heuristics that people use to judge under uncertainty. The representativeness heuristic judges a case by how closely it resembles a familiar category. To an experienced triage nurse, this patient resembled the intoxicated patients she sees often, and the resemblance was strong. The availability heuristic treats whatever springs readily to memory as more likely, and Friday-night intoxication is highly available in an emergency department. Neither heuristic is irrational. Both usually produce the right answer quickly, which is why experienced clinicians rely on them.

Why the Category Held

Once the label "likely ETOH" was written, it shaped what happened next. Croskerry (2003) described a set of cognitive errors common in clinical diagnosis, including anchoring, holding to an initial impression despite new information, and premature closure, settling on a diagnosis nobody has yet confirmed. He also described diagnosis momentum: a label, once attached, tends to be passed along and accepted by others without question. The hallway placement, the lower acuity and the note all signaled to later staff that the patient's problem was known. The second nurse checked glucose as a routine step, not because she questioned the label.

Was This Bias Against the Patient?

The analysis does not need to prove that the nurse held a prejudice against people who drink, or against this patient. The errors described here operate in anyone making fast judgments with incomplete information. They can be amplified by stereotypes, and patients who appear intoxicated may receive less careful assessment. But the case can be explained fully by heuristics and anchoring, without assuming bad intent. Ross (1977) noted that observers tend to explain others' behavior by dispositions; here the disposition inferred, drunkenness, was a story about the patient's choices that made a medical cause seem less likely to anyone reading the note.

Why Recommend a Glucose Check Rather Than Bias Training

The most effective fix targets the gap in information, not the nurse's attitudes. A rule that every patient with altered mental status receives a fingerstick glucose at triage, before an acuity level is assigned, would have supplied the one piece of information that contradicted the label. It takes less than a minute and does not depend on anyone recognizing that they might be biased. Croskerry (2003) argued for strategies such as forcing functions and checklists that make the correct step automatic. Training clinicians to be aware of bias may have value, but it relies on people noticing their own errors in the moment, which is exactly what anchoring makes difficult.

A Wider Point

The label also traveled. Diagnosis momentum means that a triage note shapes the thinking of everyone downstream. A second safeguard would require that "likely ETOH" never be recorded as an assessment until glucose and neurological screening are documented, so the label cannot be passed along before it is checked.
