Atlanta Classification of Acute Pancreatitis

Atlanta Classification of Acute Pancreatitis

A clinical risk stratification tool to gauge the severity of disease in patients with acute pancreatitis. It consists of measurements of the patient's blood pressure, serum creatinine level, and oxygenation. These are combined with evidence of hemorrhage, abscess formation, pseudocyst formation, or necrosis along with Ranson criteria, C-reactive protein levels, and APACHE-III scores.
