Highest sensitivity and specificity in distinguishing mild from severe pancreatitis
Can be used to estimate the risk of ICU mortality based on worse set of labs during a patient's first 24hrs
A extension of the Balthazar score with stratification of severity based on score.
Balthazar grading of pancreatitis
Pancreatic necrosis
The maximum score that can be obtained is 10.
Consist of 11 parameters. Five of the factors are assessed at admission, and six of the factors are assessed during the next 48 hours. 
Score of 3 or more indicates severe<unk> .
Bedside Index for Severity in<unk> 
Decreased sensitivity, but outperforms in specificity as compared to Ranson and<unk> ACHE II
Clinically more manageable to obtain, especially in the ED setting
BUN > 25 mg/dL
Impaired mental status, defined as disorientation, lethargy, somnolence
≥2 SIRS Criteria
Age > 60 years
Pleural effusion
Interpretation
Score of 0-2 had mortality < 2%
Score of 3-4 has mortality > 15%
Score of 5 has 22% mortality
