Oakland Score for Lower GI Bleeding

The Oakland score (0–35) predicts safe discharge in acute lower GI bleeding from age, sex, prior LGIB admission, rectal exam blood, heart rate, systolic BP and hemoglobin. A score ≤8 predicts a 95% probability of safe discharge for outpatient investigation (BSG 2019).

  • Age (years)
  • Sex: Male; Female
  • Previous admission with lower GI bleeding (yes/no, +1)
  • Blood on digital rectal examination (yes/no, +1)
  • Heart rate (/min)
  • Systolic blood pressure (mmHg or kPa)
  • Hemoglobin (g/dL or g/L)

Interpretation

ResultMeaning
≤ 895% probability of safe discharge (outpatient colonoscopy)
> 8Admit; risk rises with score

Formula

Age <40 = 0, 40–69 = 1, ≥70 = 2 · Male 1 · Prior LGIB admission 1 · Blood on DRE 1 · HR <70 = 0, 70–89 = 1, 90–109 = 2, ≥110 = 3 · SBP 50–89 = 5, 90–119 = 4, 120–129 = 3, 130–159 = 2, ≥160 = 0 · Hb (g/L) 36–69 = 22, 70–89 = 17, 90–109 = 13, 110–129 = 8, 130–159 = 4, ≥160 = 0

Clinical pearls

  • Hemoglobin bands are in g/L (×10 for g/dL).
  • Higher thresholds (≤10) have been validated in some cohorts and increase the proportion discharged.
  • Not for upper GI bleeding; use Glasgow-Blatchford.

FAQ

What Oakland score is safe to discharge?

A score of 8 or less predicts a 95% probability of safe discharge; BSG guidance supports outpatient investigation for these patients.
