Mortality Probability Model III (MPM III) Calculator

Clinical context

Estimates hospital mortality risk based on ICU admission criteria using logistic regression (Higgins et al., 2007). All inputs should be evaluated within 1 hour of ICU admission. • Zero factors: Mark yes if no other risk factors (besides age) are present • Full code: Full resuscitation status without any limitations (not DNR) • Medical or unscheduled surgery: Exclude elective surgeries scheduled ≥24h in advance • Coma or deep stupor: GCS ≤ 4; not due to sedation, drug overdose, or anesthesia • Heart rate ≥150 bpm: Measured within 1 hour before/after ICU admission • Systolic BP ≤90 mmHg: Measured within 1 hour before/after ICU admission • Chronic renal compromise: Documented creatinine >2 mg/dL (>175 μmol/L) and chronic in history • Cirrhosis: Biopsy-proven or clinical signs like varices from portal hypertension • Metastatic neoplasm: Stage IV disease or hematologic malignancies with systemic signs • Acute renal failure: Acute tubular necrosis or acute diagnosis on chronic renal dysfunction • Cardiac dysrhythmia: Include only unstable arrhythmias like VT, VF with rapid ventricular response, 2nd/3rd degree block, not chronic benign ones • Cerebrovascular incident: Acute stroke, infarction, or hemorrhagic event • GI bleeding: Hematemesis, melena, or active upper GI source — not just Hb drop • Intracranial mass effect: CT findings of shift, ventricle compression, or mass > 4 cm • CPR within 24h: Any CPR event including compressions or defibrillation • Mechanical ventilation: Patient is on ventilator at/before ICU admission
