PROMISS Score (Postoperative Mortality) Calculator

  • Age (years)
  • ASA Physical Status (1-5)
  • Emergency Surgery (0 = No, 1 = Yes)
  • Cardiac Failure (0 = No, 1 = Yes)
  • Renal Failure (0 = No, 1 = Yes)
  • PROMISS Score (Postoperative Mortality): Explanation and Clinical Context
    The PROMISS score is a validated tool to predict 30-day postoperative mortality in adult surgical patients. It incorporates patient age, ASA physical status, emergency surgery, cardiac failure, and renal failure.
    The model uses logistic regression to calculate the predicted probability of postoperative death, allowing clinicians to identify high-risk patients and optimize perioperative management.
    Risk interpretation: a higher percentage corresponds to higher predicted mortality, guiding preoperative counseling, resource allocation, and potential interventions.
