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.
