FA-64591 / Clinical triage scoring / Open access
Upper gastrointestinal bleed risk score and disposition: female haemoglobin table · case 01
Women with haemoglobin 11 g/dL score 3 points.
ROOT CAUSE
The male haemoglobin table is used for women as well.
VERIFIED REPAIR
Use the female bands (>=12:0, 10-11.9:1, <10:6).
Unsuccessful approach: Keeping the female thresholds but scoring < 10 g/dL as 3 under-weights severe anaemia.
Case contract
Input {urea (mmol/L), hb (g/dL), sex, sbp, hr, melena, syncope, hepatic, cardiac}. Toy points: urea < 6.5:0, 6.5-7.9:2, 8.0-9.9:3, 10.0-24.9:4, >=25:6. Hb male >=13:0, 12-12.9:1, 10-11.9:3, <10:6; female >=12:0, 10-11.9:1, <10:6. SBP >=110:0, 100-109:1, 90-99:2, <90:3. hr >= 100:1, melena 1, syncope 2, hepatic disease 2, cardiac failure 2. Disposition: 0 DISCHARGE, 1-6 ADMIT, >= 7 URGENT. Return {score, disposition}.
Why this case matters
Bleeding risk scores combine sex-specific laboratory tables with haemodynamic bands; each table edge is a separable defect.

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.
