Version de la méthode: Blatchford et al. 2000 original Glasgow-Blatchford Bleeding Score arithmetic v1 (raw integer 0–23): blood urea contributes 0, 2, 3, 4, or 6 points, scored directly in one explicit native pathway—urea mmol/L: <6.5 = 0, >=6.5 to <8.0 = 2, >=8.0 to <10.0 = 3, >=10.0 to <25.0 = 4, and >=25.0 = 6; or BUN mg/dL: <18.2 = 0, >=18.2 to <22.4 = 2, >=22.4 to <28.0 = 3, >=28.0 to <70.0 = 4, and >=70.0 = 6. The approximate factor 1 mmol/L urea = 2.8 mg/dL BUN is audit-display only and never selects a score bin; whole-urea mass in mg/dL is excluded. Hemoglobin normalizes g/L to g/dL using 10 g/L = 1 g/dL and uses an independently established explicit source category: male >=13 = 0, >=12 to <13 = 1, >=10 to <12 = 3, <10 = 6; female >=12 = 0, >=10 to <12 = 1, <10 = 6. Systolic blood pressure >=110 mmHg = 0, 100–109 = 1, 90–99 = 2, <90 = 3; heart rate >=100 beats/min = 1; melena = 1; true syncope = 2; hepatic-disease evidence = 2; cardiac-failure evidence = 2. The raw total is the unrounded sum of all eight complete component assignments; no partial score, threshold, category, probability, outcome estimate, disposition, endoscopy or transfusion decision, management, or treatment logic is supplied.
Population: People aged at least 15 years with independently established suspected acute upper-GI bleeding at one initial pre-endoscopy presentation for whom applicability of the original western-Scotland source setting is independently established. The score was developed from 1748 admissions across all 19 hospitals in west Scotland and prospectively locally validated in 197 consecutive patients admitted across three west-Scotland hospitals. Blood urea identity/unit, hemoglobin value/unit and source-defined male/female scoring category, systolic blood pressure, heart rate, melena, true syncope, hepatic-disease evidence, and cardiac-failure evidence must be explicit, complete, and anchored to the same presentation; all analyte, specimen, unit, source-value, timing, and category identities must be verified. The four qualitative markers must be explicitly clinician assessed, and the source-defined hemoglobin category and age boundary must be independently established and explicitly confirmed. This arithmetic does not establish the bleeding diagnosis, source-population applicability, or any clinical action.
Limites et exclusions: Any published or later cutoff or threshold, low/high or other result category, individual probability or prediction of intervention, death, rebleeding, transfusion, endoscopic therapy, or surgery, prognosis, reassurance, disposition, admission, discharge or outpatient-care decision, transfusion or endoscopy recommendation, monitoring, management, treatment, or any other clinical decision. · Patient age below 15 years; no independently established suspected acute upper-GI bleeding; lower-GI or nonacute bleeding; a post-endoscopy assessment; use outside the original west-Scotland source setting without independent transportability assessment; values from different episodes, presentations, or time points; or substitution of later or post-intervention values. · Missing, inferred, imputed, default-normal, carried-forward, rounded-before-scoring, nonquantitative, or otherwise unverified inputs; an unknown qualitative marker treated as absent; or a partial score. · Whole-urea mass in mg/dL, BUN in mmol/L, a generic or unverified urea identity, conversion-derived bin assignment instead of direct scoring on the selected native pathway, unsupported hemoglobin units, or inference of the source-defined male/female hemoglobin scoring category. · Unassessed qualitative markers; substitution of dizziness or presyncope for true syncope; or automatic inference of hepatic disease or cardiac failure. The original score report did not publish precise operational definitions for those comorbidities; later definitions may supply supporting context but must not be represented as original source definitions.
