FA-64356 / Clinical triage scoring / Open access

Aggregate early warning score with oxygen scale: temperature low band edge · case 01

A temperature of exactly 36.0 scores 0 instead of 1.

Verified by executionVariant 1 · 11 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The 35.1-36.0 band excludes its inclusive upper edge.

VERIFIED REPAIR

Compare temperature in tenths with t <= 360.

Unsuccessful approach: Flooring to whole degrees scores every 36.x reading as low.

Case contract

Input {rr, spo2, on_o2, scale2, temp (1 dp), sbp, hr, avpu}. Toy points: RR <=8:3, 9-11:1, 12-20:0, 21-24:2, >=25:3. SpO2 scale 1: <=91:3, 92-93:2, 94-95:1, >=96:0. Scale 2: <=83:3, 84-85:2, 86-87:1, 88-92:0, and >=93 scores 0 on air but on oxygen 93-94:1, 95-96:2, >=97:3. Oxygen +2. Temp <=35.0:3, 35.1-36.0:1, 36.1-38.0:0, 38.1-39.0:1, >=39.1:2. SBP <=90:3, 91-100:2, 101-110:1, 111-219:0, >=220:3. HR <=40:3, 41-50:1, 51-90:0, 91-110:1, 111-130:2, >=131:3. AVPU "A" 0, any other (C new confusion, V, P, U) 3. Risk: total >=7 HIGH, >=5 MEDIUM, else LOW_MEDIUM if any single parameter scores 3, else LOW. Return {score, risk}.

Why this case matters

Aggregate early warning scores drive escalation; each parameter table, the oxygen scale switch and the single-parameter trigger are separate failure points.

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.
