Coma scale total with intubated verbal component: intubated verbal substitution · case 01

Intubated patients are graded one point too severe.

Verified by executionVariant 1 · 10 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The intubated verbal component contributes 0 instead of the stipulated 1.

VERIFIED REPAIR

Count an intubated verbal as 1 for severity.

Unsuccessful approach: Assuming the best verbal response (5) grades intubated patients far too mild.

Case contract

Input {eye 1-4, verbal 1-5 or "T" (intubated), motor 1-6}. Out-of-range components return {error INVALID}. Toy rule: an intubated verbal counts as 1 for severity but the display is "<eye+motor>T"; otherwise the display is the total. Severity: 13-15 MILD, 9-12 MODERATE, 3-8 SEVERE. airway_alert is true for totals <= 8 unless already intubated. Return {display, severity, airway_alert}.

Why this case matters

Coma scale tooling mixes numeric totals with an intubation marker; validation, display and severity bands fail independently.

Verification & scope

A deterministic toy software model with explicitly stipulated thresholds and formulas; it is not clinical guidance, not a validated medical calculator, and makes no claim of conformance to any published protocol. Numbered variants vary patient and order inputs. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
