Severe acute biliary pancreatitis requiring Intensive Care Unit admission: Evaluation of severity score for the prediction of morbidity and mortality

Severity of pancreatitis is an important consideration for ED clinicians making admission judgments. The early identification of severe AP is important for the management and for improving outcomes. Validated scoring systems can be a helpful tool in this process. A multitude of predictive models has been developed to predict the severity of AP based on clinical, laboratory, and radiologic risk factors, various severity grading systems, and serum markers. This study aimed to evaluate the comparative usefulness of the Acute Physiology and Chronic Health Evaluation‐II (APACHE‐II),[1] computed tomography imaging scoring systems (CTSI) score,[1] Bedside Index of Severity in Acute Pancreatitis (BISAP) score,[1,2] Ranson score,[3] and IMIRIE score[3] to predict the prediction the morbidity and mortality in acute severe biliary pancreatitis requiring Intensive Care Unit admission.
