Ranson's criteria is one of the first scoring systems used to assess prognosis in acute pancreatitis. It consists of 11 parameters,5 assessed at admission and 6 more during the next 48 hours

The criteria are well known and of historical interest, though a meta-analysis of 110 studies found the Ranson score to be a poor predictor of severity and performed no better than clinical judgement.
