The Comparative Accuracy of BISAP and PANC3 Scoring System for the Disease Severity and Outcome in Acute Pancreatitis in Tertiary Care Hospital from North India.

Background Acute pancreatitis has local and systemic manifestations, so it's important to assess the severity by various scoring system. Among them bed side index for severity of acute pancreatitis and pancreatitis three score have been considered to be more predictive and easier. Objective To determine the comparative prognostic value of bed side index for severity of acute pancreatitis and pancreatitis 3 score and its correlation with the outcome. Method A prospective observational study was conducted on 50 cases of acute pancreatitis. The patients were assessed clinically, radiologically and biochemically and were categorised into mild, moderate and severe category as per Atlanta Classification. Bed side index for severity of acute pancreatitis and pancreatitis 3 score was calculated at the time of admission and followed till the time of discharge or they had mortality. Result Receiver operating characteristic curve, showed bed side Index for severity of acute pancreatitis score had sensitivity (66.67%), specificity (84.09%), diagnostic accuracy (84%) while pancreatitis 3 score had sensitivity (50%), specificity (81.82%), diagnostic accuracy (80%) for the severity of acute pancreatitis. Bed side index for severity of acute pancreatitis had sensitivity (100%), specificity (66.67%) and Pancreatitis 3 score had sensitivity (66.67%), specificity (80.85%) for predicting the mortality in acute pancreatitis. Conclusion Bed side index for severity of acute pancreatitis and pancreatitis 3 score are both simple, bedside tool for assessing the severity and mortality but bed side index for severity of acute pancreatitis score had better sensitivity, specificity for assessing the severity and mortality as compared to pancreatitis three score.
