Modified Marshall Scoring System for Organ Dysfunction

(For early phase of acute pancreatitis (first week ± second week of disease).)

Partial pressure of oxygen, PaO2
%
For non-ventilated patients, enter FiO2 value for the supplemental oxygen levels:
  • 21 (Room air)
  • 25 (2 L/minute)
  • 30 (4 L/minute)
  • 40 (6-8 L/minute)
  • 50 (9-10 L/minute)

The patient has
organ failure.

 

Formula

Scoring table

scoring table
  • A score of 2 or more in any system defines the presence of organ failure.
  • If organ failure affects more than one organ system, it is termed multiple organ failure (MOF).

Grades of severity by Modified Marshall scoring system

  • Mild acute pancreatitis
    - No organ failure
  • Moderately severe acute pancreatitis
    - Organ failure that resolves within 48 hours (transient organ failure)
  • Severe acute pancreatitis
    - Persistent organ failure (>48 hours)
