FA-64366 / Clinical triage scoring / Open access
Sepsis screen from inflammatory criteria and bedside score: temperature criterion · case 01
A temperature of exactly 38.0 counts as an inflammatory criterion.
ROOT CAUSE
Both temperature thresholds are treated as inclusive.
VERIFIED REPAIR
Count temperature only when strictly above 38.0 or strictly below 36.0.
Unsuccessful approach: Dropping the hypothermia clause misses low temperatures entirely.
Case contract
Input {temp (1 dp), hr, rr, paco2 (or null), wbc, bands_pct, sbp, gcs, suspected_infection}. Toy inflammatory criteria (count): temp > 38.0 or < 36.0; hr > 90; rr > 20 or paco2 < 32 when measured; wbc > 12 or < 4 or bands > 10%. Bedside score: rr >= 22, sbp <= 100, gcs < 15. Without suspected infection the alert is NONE; otherwise SEPSIS_ALERT when the bedside score >= 2, else SIRS_ALERT when criteria >= 2, else NONE. Return {sirs, qsofa, alert}.
Why this case matters
Screening rules count criteria with open and closed thresholds and combine two scores with precedence; each 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.
Observations recorded using Python 3.12.14 at 2026-09-29T14:47:23.831327+00:00.
