Module 4 — Boundary Drill

By William Aird

Severe Anemia in the Hospitalized Patient
Where Does This Information Belong?

1. How this module fits in Consult Practice

LensWhat it contributes here
OrientationDefines terrain
ThinkingAssigns stance
ExecutionMakes behavior and communication explicit

2. What this module is for

To help clinicians practice assigning clinical information into the correct cognitive domain.

3. How to use this module

Use this as a quick teaching or reflection drill:

  • during rounds
  • during consult handoffs
  • when reasoning feels blurred
  • when trainees are conflating interpretation with action

4. Why this matters

Most consult errors arise from category confusion, not knowledge deficits.

When terrain, stance, and action blur together:

  • urgency is misjudged
  • uncertainty is mishandled
  • and premature closure becomes more likely

This drill reinforces cognitive boundary discipline.

5. Core Content

Sorting Exercise

StatementDomainWhy
“Hemoglobin fell from 8.5 to 5.0 overnight.”Orientationdefines tempo
“This is a reserve-threat problem requiring vigilance.”Thinkingdefines stance
“We will transfuse now to stabilize oxygen delivery.”Executionvisible behavior
“Platelets and WBC are also declining.”Orientationbroadens terrain
“We will revise our concern as the counts stabilize.”Thinkingrevisability posture

Teaching prompt
Which findings define the terrain, which define posture, and which define what must become visible?

6. Bottom line

This module reinforces the discipline of separating:

  • terrain from stance
  • and stance from action

That separation is a core skill of expert consult judgment.
