A comparative study between BISAP score and HAPS score as predictors of severity in acute pancreatitis

Abstract

Introduction: Acute pancreatitis (AP) is a potentially life-threatening condition, with early prediction of severity being crucial for better management and outcomes. Various scoring systems exist to assess the severity of AP. The Bedside Index for Severity in Acute Pancreatitis (BISAP) and Harmless Acute Pancreatitis Score (HAPS) are two commonly used tools. This study aims to compare the accuracy of BISAP and HAPS scores in predicting the severity of AP.
Methodology: A hospital-based comparative study was conducted on 60 patients diagnosed with acute pancreatitis at a tertiary care center. Patients were evaluated using both BISAP and HAPS scoring systems within 24 hours of admission. The scores were then compared with clinical outcomes, including the development of organ failure, necrosis, intensive care unit (ICU) admission, and mortality rates. Data analysis was performed to determine the predictive value of each scoring system in relation to severity indicators.
Results: The BISAP score showed a higher sensitivity and specificity in predicting severe acute pancreatitis compared to the HAPS score. BISAP score >3 was significantly associated with complications like organ failure and ICU admission, while HAPS score had a lower predictive accuracy. Mortality was better predicted by BISAP, while HAPS was more effective in ruling out severe cases in mild presentations.Conclusion: The BISAP score is more effective than the HAPS score in predicting the severity of acute pancreatitis, especially in high-risk patients. Early use of BISAP can aid in better management and improved outcomes.
