Version de la méthode

Conventional Ranson 1982 two-variant historical raw-count arithmetic v1. Non-gallstone variant (raw integer 0–11): at admission, completed age >55 years, peripheral white-blood-cell count >16,000 cells/mm³, blood glucose >200 mg/dL, serum LDH >350 U/L, and serum AST >250 U/L; over the complete first 48 hours, admission-to-nadir hematocrit fall >10 percentage points, admission-to-peak BUN rise >5 mg/dL, nadir measured uncorrected total serum calcium <8 mg/dL, nadir arterial PaO2 <60 mmHg, maximum positive base-deficit magnitude >4 mEq/L, and clinician-verified estimated fluid sequestration >6 L. Gallstone variant (raw integer 0–10): at admission, completed age >70 years, peripheral white-blood-cell count >18,000 cells/mm³, blood glucose >220 mg/dL, serum LDH >400 U/L, and serum AST >250 U/L; over the complete first 48 hours, hematocrit fall >10 percentage points, BUN rise >2 mg/dL, nadir measured uncorrected total serum calcium <8 mg/dL, maximum positive base-deficit magnitude >5 mEq/L, and clinician-verified estimated fluid sequestration >4 L. Arterial PaO2 is not a gallstone component and must be omitted. Every printed inequality is strict, exact equality contributes zero, paired hematocrit and BUN changes are derived without rounding, and the raw count is the unrounded sum of all applicable booleans. Fixed source-native identities and units only; no conversion, substitution, partial count, historical threshold, category, probability, or care logic is supplied.

Population

Adults age 18 through 120 years for whom acute pancreatitis and exactly one conventional non-gallstone or gallstone etiology variant are independently established as applicable. This age restriction is a conservative app boundary, not a claim that every historical source excluded younger patients. Admission values and all required nadirs, peaks, maximum positive magnitude, and estimated sequestration must belong to one index hospital-admission record through the complete and final first 48 hours. Hematocrit and BUN must be explicit paired series from that same record; all source values, extrema, analyte identities, assay context, units, timing, and completeness must be verified independently outside the app.

Limites et exclusions

Unknown, mixed, or indeterminate etiology; a transfer-arrival or symptom-onset time substituted for the index admission; an admission-only, partial, still-evolving, later, mismatched, or different-episode record; a missing, inferred, imputed, default-normal, carried-forward, rounded-before-scoring, or nonquantitative source value; or a partial component count. · Serum urea substituted for BUN; corrected or ionized calcium substituted for measured uncorrected total serum calcium; SpO2, SaO2, venous oxygen, or an inferred oxygen value substituted for arterial PaO2; base excess, pH, or a signed negative value substituted for maximum positive base-deficit magnitude; administered-fluid volume or an app-derived balance substituted for clinician-verified estimated sequestration; or any converted, unsupported, or unverified unit or measurement identity. · Arterial PaO2 supplied to the gallstone variant; omission of arterial PaO2 from the non-gallstone variant; an inconsistent paired record with hematocrit nadir above admission hematocrit or BUN peak below admission BUN; altered component definitions, thresholds, variants, timing windows, or source coefficients. · The historical published >=3 interpretation, any cutoff, threshold interpretation, result group or category, severity statement, probability, mortality or survival estimate, diagnosis or diagnostic confirmation, prognosis, reassurance, disposition, ICU or surgical decision, imaging, monitoring, feeding, fluid, analgesia, antibiotic, management, treatment, or recommendation.
