title: A prospective study of the Bedside Index for Severity in Acute Pancreatitis (BISAP) score in acute pancreatitis: an Indian perspective.
abstract: BACKGROUND
  A simple and easily applicable system for stratifying patients with acute pancreatitis is lacking. The aim of our study was to evaluate the ability of BISAP score to predict mortality in acute pancreatitis patients from our institution and to predict which patients are at risk for development of organ failure, persistent organ failure and pancreatic necrosis.
  
  
  METHODS
  All patients with acute pancreatitis were included in the study. BISAP score was calculated within 24 h of admission. A Contrast CT was used to differentiate interstitial from necrotizing pancreatitis within seven days of hospitalization whereas Marshall Scoring System was used to characterize organ failure.
  
  
  RESULTS
  Among 246 patients M:F = 153:93, most common aetiology among men was alcoholism and among women was gallstone disease. 207 patients had no organ failure and remaining 39 developed organ failure. 17 patients had persistent organ failure, 16 of those with BISAP score ≥3. 13 patients in our study died, out of which 12 patients had BISAP score ≥3. We also found that a BISAP score of ≥3 had a sensitivity of 92%, specificity of 76%, a positive predictive value of 17%, and a negative predictive value of 99% for mortality.
  
  
  CONCLUSIONS
  The BISAP score is a simple and accurate method for the early identification of patients at increased risk for in hospital mortality and morbidity.
