BISAP Score Calculator

The BISAP Score estimates the severity of acute pancreatitis. Simply enter patient details like blood test results, age, and symptoms to find the score and risk level. This estimate helps doctors understand how sick a patient might be. This calculator also calculates estimated mortality risk.

Enter the BUN value from the blood test (e.g., 24)
Select Yes if the patient is confused or disoriented
Select Yes if the patient meets SIRS criteria
Enter the patient's age in whole years
Select Yes if imaging shows fluid around the lungs

What Is BISAP Score

The BISAP Score is a simple checklist doctors use at the bedside. It looks at five specific signs in a patient with pancreatitis. Each sign adds a point to the total score. A higher score usually means the illness is more serious. It helps predict the chance of death from the disease.

How BISAP Score Is Calculated

Formula

Score = (BUN > 25) + (Mental Status) + (SIRS) + (Age > 60) + (Pleural Effusion)

Where:

  • BUN = Blood urea nitrogen level
  • Points added for each condition present (1 point each)

The score adds up points from five different checks. You get one point if your blood urea nitrogen is high. You get points for being confused, having signs of body-wide inflammation, being older than 60, or having fluid around the lungs. Adding these points gives a total from 0 to 5.

Why BISAP Score Matters

Knowing this score helps medical teams decide where a patient should get care. It helps them spot who might need extra help right away.

Why Early Detection Is Important for Patient Care

Finding severe cases early is very important. If the score is high, the patient may need to go to the intensive care unit. Early care can help prevent serious problems. However, this score is just one tool and does not tell everything about a patient's health.

For Older Patients

Older people often have higher scores because age is a factor in the calculation. They might get sicker faster than younger people, so doctors watch them closely. A high score in an older patient suggests a greater need for careful monitoring.
