Version de la méthode

Blamey–Imrie 1984 source-locked eight-factor modified Glasgow–Imrie historical raw-count arithmetic v1 (raw integer 0–8): one point each for completed age >55 years; maximum peripheral white-blood-cell count >15 ×10^9/L; maximum blood glucose >10 mmol/L only when pre-existing diabetes history at index admission is absent; maximum serum urea >16 mmol/L only when clinician-established nonresponse to initial IV fluid is present; maximum serum LDH >600 U/L; minimum measured total serum calcium <2.00 mmol/L; minimum arterial PaO2 <60 mmHg; and minimum serum albumin <32 g/L. All extrema come from one index hospital admission through the complete first 48 hours, inclusive. Every inequality is strict, exact equality contributes zero, and the raw count is the unrounded sum of the eight booleans. This is the 1984 modification: the AST/ALT component from the original 1978 nine-factor version is omitted. Fixed source-native units and identities only; no conversion, imputation, partial count, historical threshold, category, probability, or care logic is supplied.

Population

Adults age 18 years or older for whom primary acute pancreatitis, exclusion of secondary acute pancreatitis, and applicability of the historical Blamey–Imrie 1984 source context are independently established. The 1984 prospective study included 347 patients with 405 episodes. The complete final record must span one index hospital admission through the inclusive first 48 hours; maxima and minima must be selected from that same window. Pre-existing diabetes history and clinician-established urea response to initial IV fluid must be explicitly verified outside the app. Every required value, status, analyte, specimen, measurement identity, source-native unit, assay context, timing, and record-completeness fact must be verified.

Limites et exclusions

A patient younger than 18 years; secondary acute pancreatitis; an unverified source context; symptom onset or transfer arrival 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. · BUN substituted for serum urea; corrected or ionized calcium substituted for measured total serum calcium; SpO2, SaO2, venous oxygen, or inferred oxygen substituted for arterial PaO2; another glucose, LDH, albumin, or white-cell identity; converted or unsupported units; or an unverified analyte, specimen, assay, or measurement identity. · Unknown pre-existing diabetes history; diabetes inferred from the glucose value; unknown urea response; urea nonresponse inferred from a concentration or an app-created fluid protocol; incomplete observation-window extrema; or treating an unmeasured component as absent. · The original 1978 nine-factor system, AST or ALT input, a later hybrid, altered component definitions or thresholds, the historical published >=3 interpretation, any cutoff, threshold interpretation, result group or category, severity statement, probability, mortality or survival estimate, diagnosis, prognosis, reassurance, disposition, ICU or surgical decision, imaging, monitoring, fluid protocol, management, treatment, or recommendation.
