BISAP Score Cutoff for Severe Acute Pancreatitis and In‑Hospital Mortality
A BISAP score cutoff of ≥3 is supported as a statistically significant early threshold for predicting severe acute pancreatitis and death. [1]
Recommended BISAP Cutoff for Predicting Severe Disease
In a prospective observational cohort (n=60), BISAP ≥3 served as the identified cutoff associated with severe acute pancreatitis. [1]
Recommended BISAP Cutoff for Predicting In‑Hospital Mortality
In the same prospective observational cohort, BISAP ≥3 was also reported as the statistically significant cutoff for prediction of mortality. [1]
Predictive Accuracy Versus APACHE II for Severe Disease
In the prospective observational cohort, the diagnostic/prognostic discrimination (AUC) for severe acute pancreatitis was reported as:
- BISAP: 0.875
- APACHE II: 0.891 [1]
Predictive Accuracy Versus APACHE II for In‑Hospital Mortality
In the prospective observational cohort, the discrimination (AUC) for death was reported as:
- BISAP: 0.740
- APACHE II: 0.769 [1]
Cross‑Study Support for Mortality Discrimination Using BISAP
An additional retrospective evaluation of consecutive acute pancreatitis admissions reported high discrimination for mortality with BISAP, with BISAP mortality AUC = 0.940 (definition of severe disease differed across studies). [2]
Practical Interpretation of the BISAP ≥3 Threshold Relative to APACHE II
Across published early-evaluation cohorts, BISAP ≥3 is associated with meaningful risk stratification for severe disease. [1]
Across the same cohort, APACHE II demonstrated slightly higher AUC for mortality than BISAP, while AUCs for severe disease were very close. [1]
