• A number of systems exist to identify severity and prognosticate pancreatitis
    • Considered advantageous over clinical judgement alone
    • Useful in determining optimum location of care
  • Limitations exist with many of the scoring systems:
    • Cumbersome to complete
    • Require 48 hours to gather variables for some scores
    • Lack accuracy in early stages
    • Limited clinical value
Classification Systems

Atlanta Criteria

  • Divides pancreatitis in to two pathophysiological types:
    • Interstitial oedematous pancreatitis
    • Necrotising pancreatitis
    • Classifies severity as mild, moderate and severe
  • Determined by presence of local features and organ failure
Prognostic Scoring Systems
Disease Specific


  • Ransoms:
    • Originally designed for gallstone-induced pancreatitis
    • Uses age, nine laboratory parameters plus fluid requirements to calculate a score over 48 hours
    • A score of >3 at 48 hours indicates the presence of severe pancreatitis
  • Glasgow-Imrie:
    • Requires 48 hours to complete
    • Uses age and seven laboratory parameters to predict severe pancreatitis


  • Balthazar CT grade
    • A score of >8 at 24 hours defines severe acute pancreatitis
