Oakland Score for Safe Discharge After Acute Lower GI Bleeding
x402
Oakland Score for Safe Discharge After Acute Lower GI Bleeding is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Computes the Oakland 2017 risk score (0–35) to determine whether a patient with acute lower gastrointestinal bleeding can be safely discharged from the emergency setting.

How this service works
Oakland 2017 risk score for safe discharge after acute lower gastrointestinal bleeding. Points from age (0-2), sex (male 1), previous LGIB admission (1), caller-assigned blood on digital rectal examination (1), heart rate (0-3), systolic BP (0-5), and hemoglobin g/dL (0-22); max 35. safe_discharge when score ≤8 (derivation cutoff, not a later US validation). Not a discharge order or LGIB diagnosis. magent does not examine the rectum or assay hemoglobin. Hemoglobin g/dL or g/L.
Output
Returns the total Oakland score (integer 0–35) and a safe_discharge flag (true when score ≤8, based on the original derivation cutoff). May also return individual point contributions per variable (age, sex, previous LGIB, DRE blood, heart rate, systolic BP, hemoglobin).
Example use cases
ED triage for rectal bleeding patient
“Can you calculate the Oakland score for a 68-year-old female presenting to the ED with fresh rectal bleeding — heart rate 82 bpm, systolic BP 128 mmHg, hemoglobin 11.4 g/dL, no prior LGIB admissions, and no blood on DRE?”
Elderly male with prior LGIB history
“Score this patient for safe discharge: 81-year-old male, previous LGIB admission, blood found on rectal exam, heart rate 112 bpm, systolic BP 88 mmHg, hemoglobin 7.5 g/dL — using the Oakland 2017 criteria.”
Automated EMR documentation support
“For our discharge review workflow, compute the Oakland 2017 LGIB score for a 45-year-old male with heart rate 66 bpm, systolic BP 145 mmHg, hemoglobin 13.8 g/dL, no previous LGIB, and negative rectal exam.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/oaklandWhen to prefer
Use this endpoint when you need to programmatically compute the Oakland 2017 score for acute lower gastrointestinal bleeding and assess whether a patient meets the derivation-defined safe-discharge threshold (≤8 points). Prefer this over manual calculation when integrating into clinical decision-support workflows, EMR automation, or agent-driven triage pipelines. Note that this is a scoring aid, not a discharge order — clinical judgment is required.
Side effects
- Missing required parameter (age, sex, heart rate, systolic BP, previous_lgib_admission, or dre_blood) returns a validation error
- Hemoglobin value below 3.6 g/dL (after conversion) is rejected with an out-of-range error
- Providing both hemoglobin_g_dl and hemoglobin_g_l simultaneously is rejected
- Age outside 16–120 or heart rate outside 30–220 fails input validation
- Invalid enum for sex (not 'male' or 'female') returns a schema error
