How it works
HAPS identifies patients unlikely to develop severe pancreatitis when all three clinical/laboratory criteria are absent at assessment.
Limits
Does not replace imaging, scoring systems for severe disease, or ICU criteria; not for identifying high-risk pancreatitis.
Educational tool only—not for diagnosis or treatment decisions.
