Harmless Acute Pancreatitis Score (HAPS)

Identifies patients with harmless acute pancreatitis who can be managed without intensive monitoring. All three negative criteria must be absent to classify as harmless.

Used in: Acute Pancreatitis

Score interpretation

Harmless Acute Pancreatitis 0

All HAPS criteria negative — harmless acute pancreatitis predicted (negative predictive value >98%)

→ Regular ward care; oral diet as tolerated; no ICU admission needed

Potentially Severe 1–3

≥1 HAPS criterion positive — harmless pancreatitis cannot be predicted

→ Full assessment with Ranson/BISAP/APACHE-II; CT imaging if indicated; consider HDU/ICU

Interpretation bands for the HAPS. Apply clinical judgement and local guidance.
