Version de la méthode: Oakland et al. 2017 original canonical seven-variable point arithmetic, oakland-2017-seven-variable (raw integer 0–35): completed age <40 years = 0, 40–69 = 1, and >=70 = 2; published source sex category female = 0 and male = 1; any previous lower-GI-bleeding episode resulting in hospital admission = 1 and no such admission = 0; blood found on an actual digital rectal examination = 1 and no blood = 0; heart rate <70 beats/min = 0, 70–89 = 1, 90–109 = 2, and >=110 = 3; systolic blood pressure 50–89 mmHg = 5, 90–119 = 4, 120–129 = 3, 130–159 = 2, and >=160 = 0; hemoglobin >=36 to <70 g/L (>=3.6 to <7 g/dL) = 22, >=70 to <90 g/L (>=7 to <9 g/dL) = 17, >=90 to <110 g/L (>=9 to <11 g/dL) = 13, >=110 to <130 g/L (>=11 to <13 g/dL) = 8, >=130 to <160 g/L (>=13 to <16 g/dL) = 4, and >=160 g/L (>=16 g/dL) = 0. The raw total is the unrounded sum of all seven complete component assignments, bounded 0–35. The original table does not assign systolic pressure below 50 mmHg or hemoglobin below 36 g/L (3.6 g/dL), so this implementation fails closed instead of extrapolating. No partial score, cutoff, threshold, category, probability, outcome estimate, disposition, or care logic is supplied.
Population: People age 16 years or older at one initial presentation with acute overt bleeding independently assessed as lower-GI in the original source context, for whom the canonical 2017 seven-variable Oakland model is independently established as applicable. The original derivation included 2,336 prospectively identified acute admissions across 143 UK hospitals in 2015; the first independent UK validation included 288 presentations and enrolled people age 18 years or older, so ages 16–17 have derivation but not that first independent-validation coverage. Completed age, the independently established published female/male source category, any previous lower-GI-bleeding episode resulting in hospital admission, blood found on an actual digital rectal examination, and the first verified heart rate, systolic pressure, and hemoglobin from the same initial assessment must all be explicit, complete, and verified with their identities, units, timing, and source values.
Limites et exclusions: Age below 16 years; bleeding not independently assessed as acute overt lower-GI bleeding; an established upper-GI source; inpatient-onset bleeding; an interfacility transfer; or values from a different episode, presentation, or time point. · A DRE-omitted or otherwise modified Oakland model, a continuous probability model, an unperformed or undocumented digital rectal examination, patient-reported blood substituted for the examination finding, or an unknown examination finding treated as no blood. · Missing, inferred, imputed, defaulted, carried-forward, rounded-before-scoring, later, worst, best, post-transfusion, discharge, or otherwise unverified inputs; unsupported hemoglobin units; systolic pressure below 50 mmHg; hemoglobin below 36 g/L or 3.6 g/dL; or extrapolation outside a published point row. · Inference of the published female/male source category from name, gender identity, anatomy, laboratory values, or therapy; changing hemoglobin bins according to that category; or representing the category as a broader clinical identity determined by this calculator. · Any cutoff, threshold, low/high or other result category, individual probability, outcome estimate, diagnosis, prognosis, reassurance, disposition, current-admission or discharge decision, outpatient-care claim, endoscopy or transfusion decision, monitoring, management, treatment, recommendation, or other clinical action.
