Oakland Score for Lower GI Bleeding

Facilitates deciding whether safe discharge of patients after Lower GI Bleeding (LGIB) is possible or not.

Refer to the text below the calculator for more information about the score and its application in clinical practice.


The Oakland Score helps risk-stratify patients presenting with lower gastrointestinal bleeding who are at low risk of adverse outcomes and likely to not need any in-hospital intervention.


  • Safe discharge is defined as absence of rebleeding, blood transfusion, therapeutic intervention, 28-day readmission, or death.
  • For scores 0 – 8: Consider discharge, with appropriate precautions.
  • For scores >8: Admission with further workup and resuscitation as necessary.

The Oakland Score for LGIB Explained

The Oakland Score is used in emergency and primary care settings to determine whether safe discharge and outpatient management is feasible in the case of patients presenting with lower gastrointestinal bleeding.

Safe discharge is defined as absence of rebleeding, blood transfusion, therapeutic intervention, 28-day readmission, or death.

The Oakland Score was developed from prospective data obtained from 2,336 patients with LGIB across 143 hospitals in the United Kingdom. Multivariable logistic regression modelling was used to identify predictors of safe discharge.

Further validation took place in 288 patients (out of which 184 were safely discharged) across 2 hospitals.

Age, sex, previous admission for lower gastrointestinal bleeding, rectal examination findings, heart rate, systolic blood pressure, and haemoglobin concentration strongly discriminated safe discharge in the development cohort (C statistic 0·84, 95% CI 0·82–0·86) and in the validation cohort (0·79, 0·73–0·84).

Oakland Scores range from 0 to 35. As a rule of thumb, patients with minor, self-limiting bleed (characteristic of scores of 8 points or less) may be discharged for urgent outpatient investigation. Patients with major bleed (scores greater than 8 points) should be admitted for colonoscopy and in case they are or become hemodynamically unstable should be admitted for urgent CT angiography.
