How this service works
Wu 2008 BISAP for early mortality prediction in acute pancreatitis: BUN >25 mg/dL, caller-assigned impaired mental status, caller-assigned SIRS, age >60, and caller-assigned pleural effusion; 1 point each, max 5. BUN 25.0 and age 60 do not score. Score only; no mortality percentages. Not a diagnosis. Not Ranson, APACHE II, or CTSI. magent does not recompute SIRS, assign mental status, or read imaging.
Output
An integer BISAP score from 0 to 5 reflecting the number of positive criteria (BUN >25 mg/dL, impaired mental status, SIRS, age >60, pleural effusion). No mortality percentages are included. The score does not constitute a diagnosis.
Example use cases
ED triage of acute pancreatitis
“My patient in the ED is 72 years old, BUN is 38 mg/dL, they have SIRS, no impaired mental status, and imaging shows a pleural effusion — what's their BISAP score?”
ICU admission severity documentation
“I need to document a BISAP score for a 55-year-old pancreatitis admission: BUN is 20 mg/dL, no SIRS, no mental status changes, and no pleural effusion.”
Comparing severity across pancreatitis patients
“Score BISAP for two pancreatitis patients — patient A is 61 years old, BUN 26, SIRS positive, mentally intact, no pleural effusion; patient B is 58, BUN 22, no SIRS, altered mental status, pleural effusion present.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/bisapWhen to prefer
Use this endpoint when you need a deterministic, published BISAP score per Wu 2008 and have already assessed SIRS, mental status, and imaging yourself — this endpoint does not recompute SIRS from vitals, assign mental status, or interpret imaging. Prefer this over Ranson, APACHE II, or CTSI when you want a simple bedside 5-point score validated for early mortality prediction in acute pancreatitis. Not appropriate if you need mortality percentage estimates or a diagnostic conclusion.
Side effects
- Missing required parameters (age, bun_mg_dl, impaired_mental_status, sirs, pleural_effusion) returns an error
- BUN value outside valid range 1–200 mg/dL may be rejected
- Age outside valid range 18–120 may be rejected
- Non-boolean values for sirs, impaired_mental_status, or pleural_effusion cause schema validation failure
- Boundary values (BUN exactly 25.0, age exactly 60) correctly score 0 — callers may be surprised these do not score
