Oakland score for lower gastrointestinal bleeding

The Oakland score uses age, sex, prior lower GI bleeding, rectal exam, heart rate, blood pressure and hemoglobin to identify patients with acute lower GI bleeding who are safe for discharge.

What goes into the Oakland score

  • Age: < 40 (0); 40–69 (1); ≥ 70 (2)
  • Sex: Female (0); Male (1)
  • Previous admission for lower GI bleeding (+1)
  • Blood on rectal exam (+1)
  • Heart rate: < 70 (0); 70–89 (1); 90–109 (2); ≥ 110 (3)
  • Systolic BP: ≥ 160 (0); 130–159 (2); 120–129 (3); 90–119 (4); 50–89 (5)
  • Hemoglobin: ≥ 16 g/dL (0); 13–15.9 g/dL (4); 11–12.9 g/dL (8); 9–10.9 g/dL (13); 7–8.9 g/dL (17); < 7 g/dL (22)

How to interpret the result

  • ≤ 8: about 95% probability of safe discharge
  • > 8: admit

Clinical pearls

  • Hemodynamically unstable hematochezia may be an upper GI bleed: check BUN and consider upper endoscopy.
  • Colonoscopy is not usually urgent; CT angiography first if bleeding is brisk.
  • Use the Glasgow-Blatchford score for suspected upper GI bleeding instead.
