Assessment of accuracy of BISAP score as a predictor of severe acute pancreatitis: a retrospective study

Abstract

Background: The prevalence of acute pancreatitis (AP) has increased in the past 20 years. Most patients with AP experience a clinical course that is mild and self-limited. However, 10% to 20% of patients develop a rapidly progressive inflammatory response necessitating prolonged length of hospital stay and high rates of morbidity and mortality. There are various scoring systems already in place to assess the severity of acute pancreatitis. However, they have significant drawbacks. Since the BISAP score offers the advantages of being inexpensive, rapid, and simple, we conducted this study to gauge its usefulness. Methods: This study enrolled 138 patients with AP admitted in surgical wards of McGann District Teaching Hospital, during a time period between January 2022 to June 2022, meeting the various inclusion criteria. Results: We found that the percentage of severity, necrosis, organ failure, death, and hospital stay increased as the BISAP score increased. In terms of sensitivity and specificity, the accuracy of the BISAP score for predicting severe acute pancreatitis was 76.2% and 63.4%. According to our study, patients with severe acute pancreatitis had BISAP scores of 3 or above. Conclusions: BISAP can be used to identify the patients who are at risk, and this information can serve as an early guidance for appropriate and necessary therapy, improving patient outcomes. Present study concludes the increased accuracy of BISAP score for risk stratification.
