BISAP — Acute pancreatitis

BISAP — Acute pancreatitis

Principle

Initial prognostic stratification of confirmed acute pancreatitis.

Scope

Adult with diagnosed acute pancreatitis. Data from the first 24 h of hospitalisation, including the emergency department; worst laboratory and vital-sign measurements in that window.

Interpretation limits

In-hospital mortality prognosis after acute pancreatitis diagnosis; not a diagnosis or automatic disposition or critical care decision. The total 0–5 does not supply an individual probability. The study imputed missing data as normal; this capsule refuses that imputation and produces no incomplete total, without prescribing investigations to complete the score. Do not confuse BUN and total urea.

Formula and logic

BUN > 25 mg/dL + altered mental status + SIRS + age > 60 years + pleural effusion: one point per criterion.
