Performance of the Bedside Index for Severity in Acute Pancreatitis (BISAP), Acute Physiology and Chronic Health Examination (APACHE)‐II, and Ranson scores in 18 studies with a pooled pre‐test probability of 18.7% for severe acute pancreatitis. The post‐test probabilities when the scores were positive were similar: 48% for BISAP, 46% for APACHE‐II, and 50% for Ranson. However, when the scores were negative, the post‐test probability dropped to 7% for BISAP, 6% for Ranson, and 5% for APACHE‐II.
