Glasgow Prognostic Criteria in Acute Pancreatitis (Imrie Criteria)

Purpose: To identify patients with acute pancreatitis who have severe disease based on information collected during the first 48 hours from admission.

Description

The Glasgow system is a simple prognostic system that uses the data collected during the first 48 hours following an admission for pancreatitis. The criteria for point assignment is that a certain breakpoint be met at anytime during that 48 hour period, so that in some situations it can be calculated shortly after admission. It is applicable to both biliary and alcoholic pancreatitis.


The original system used 9 data elements. This was subsequently modified to 8 data elements, with removal of assessment for transaminase levels (either AST (SGOT) or ALT (SGPT) greater than 100 U/L).

 

Parameters used:

(1) age in years

(2) serum albumin

(3) PaO2 on room air

(4) serum calcium

(5) blood glucose

(6) serum LDH

(7) BUN

(8) WBC count

modified Glasgow prognostic criteria =

= SUM(points for all 8 parameters)

 

Interpretation:

• minimum score 0

• maximum score 8

• If the score >=3, severe pancreatitis likely.

• If the score < 3, severe pancreatitis is unlikely.
